Alexandria Minerals Corporation  reports on preliminary results from the recently completed, down-hole Induced Polarization (“IP”) Survey on its Akasaba property. Survey results yielded several strong targets on both the main Akasaba Mine Trend and the nearby parallel North Zone, adding to high priority drill targets in preparation for this summer’s drill program.

The principal geophysical targets on the main Akasaba and North Zones are up to 400m long along strike, open to the east, and open at depth. The anomalies, located below and to the east of the Akasaba Current Resources, are similar to those intersected by previously completed gold-bearing drill holes that contain 11.35 g/t Au over 6.0 m, 6.19 g/t Au over 5.05 m, and 4.69 g/t over 5.00 m (see Figures 1 and 2 below).

To view Figure 1, please visit the following link: http://media3.marketwire.com/docs/Figure1_AZX.pdf.

Eric Owens, President and CEO, stated “These are very encouraging results, and we are looking forward to testing these targets with drill holes. Through geophysical surveys and this past winter’s drilling, we have generated several strong targets for this summer’s 10,000 m drill campaign in an effort to build on our existing gold resources. We are still awaiting further geophysical results and drill assay results, which should provide further targets for testing.”

The borehole geophysical (Hole-to-Hole Resistivity/IP) survey was conducted during the winter by Abitibi Geophysics. The survey was designed to investigate potential targets at depth around the Akasaba Current Resources. The survey used a conventional induced polarization technique, with a borehole-to-borehole array based on 19 pairs of holes. Once all the data combinations are collected, a 3D inversion uses all the readings simultaneously in order to estimate the location and volume of the anomalies. Validation of the geophysical results are provided by past Alexandria drill hole assays, which show excellent correlation between well mineralized gold-bearing zones and strong Induced Polarization anomalies.

Elsewhere, the Company is awaiting assay results from the recently completed 4,000 m drill program on its Sleepy project, located 12 km east of the Akasaba project.

GEOLOGY

The Akasaba property straddles the Cadillac Tectonic Zone (CTZ) and is underlain by the Val d’Or Formation, Heva Formation, Cadillac, Piche and Pontiac Groups. The main Mine Horizon lies approximately 600 m north of the CTZ and consists of basalt-andesite-rhyolite volcaniclastic rocks, tuffs and flows intruded by gabbro and diorite sills, and is bound on the south by massive dacite.

Akasaba hosts polymetallic mineralization, with widespread silver (up to 50 g/t) and copper (generally 0.2-0.4%, locally up to 1-2%), and local high grade zinc (up to 6.35% Zn over 0.3 m in a massive sphalerite-pyrrhotite layer), and local molybdenum. The following characteristics are pertinent to the any operating model:

  • Gold and gold-copper resources are hosted in a shear zone (the “Mine Horizon”)
  • There are numerous similar sub-parallel gold mineralized zones in addition to the Mine Horizon
  • The Callahan tonalite intrusion, which is located a short distance northwest of the deposit has a prominent metamorphic/metasomatic halo, characterized by widespread and locally intense calcium and iron metasomatism (“Skarn”), in the form of epidote, chlorite, magnetite, amphibole, garnet
  • The Mine Horizon, with gold , copper and molybdenum, and other base metals, occurs within the metasomatic halo
  • Within the Mine Horizon, there is an east west zonation relative to the Callahan Intrusive: proximal Au-Cu-Mo, medial Gold (+/- Ag, Cu), distal Ag, Zn
  • Host volcanic rocks contain up to 30% or more pyrrhotite (+/- Chalcopryite, Sphalerite) as lenses, pods and layers, and massive layers of intergrown pyrrhotite and sphalerite, suggesting a component of synvolcanic mineralization probably unrelated to gold.

Such characteristics are similar to those found in the La Ronde-Doyon-Bousquet district 45 km to the west, a gold-copper-zinc enriched mining district which has seen more than 26 million ounces of gold produced from a 7 km long trend, a trend that is 1/5 of the size of Alexandria’s property.


Ground geophysics in Greenland for nickel-copper-cobalt-PGM project

Posted by on Tuesday, 29 April, 2014

North American Nickel Inc. announces that Crone Geophysics of Mississauga, Ontario have mobilized their crews to the Imiak Hill Conduit Complex (IHCC), part of the Company’s 100% owned Maniitsoq nickel-copper-cobalt-PGM project in southwest Greenland.

Geophysical Surveys Underway

The geophysical survey work now underway consists of surface time-domain PEM and gravity surveys in the Imiak Hill Conduit Complex, where significant nickel-copper-cobalt PGE mineralization has been intersected in drill holes by the company over the past two drill seasons. These intersections include:

  • Imiak Hill DDH MQ-13-028: 24.75 metres of near massive to massive sulphide grading 3.19% Ni, 1.14% Cu, 0.11% Co, including; 17.91m of 3.80% nickel, 1.42% copper, 0.13% cobalt and 0.01 g/t PGM;
  • Imiak North DDH MQ-13-029: 55.75m of disseminated to near massive and massive sulphide grading: 1.28% nickel, 0.36% copper, 0.04% cobalt, and 0.03 g/t PGM, including;9.99m of 4.65% nickel, 0.33% copper, 0.13% cobalt and 0.08 g/t PGM; and
  • Spotty Hill DDH MQ-12-005: 123.94 meters of disseminated, net-texture, to near massive and massive sulphide grading 0.81% nickel, 0.21% copper, 0.03% cobalt & 0.26 g/t platinum (Pt) + palladium (Pd) + gold (Au), including: 24.20 m @ 1.75% Ni, 0.34% Cu, 0.06% Co & 0.52 g/t Pt+Pd+Au.

Geological Team Meeting April 8-10, 2014 in Winnipeg

As preparation for the 2014 field and drill program all norite-hosted nickel sulphide mineralized drill targets were reviewed by the NAN Geological team and four invited geoscientists familiar with nickel sulphide deposits and advanced methods of interpretation of geophysical responses to nickel sulphide mineralization. The review was undertaken at a meeting convened in Winnipeg by North American Nickel with a view to expanding discovery possibilities and then confirming and prioritizing drill targets for this year’s drill program.

President Dr. Mark Fedikow P.Geo. states: “Our deepest hole to date at Imiak Hill in the IHCC intersected high-grade massive sulphide nickel-copper mineralization 185 m below surface. The new geophysical ground surveys are designed to look below that depth and define the extent and shape of our high-grade mineralized zones providing plunge, strike and dip attitudes for the mineralization. The results from these 2014 ground geophysical surveys coupled with the airborne surveys and drill results from 2012 and 2013 will assist with drill targeting at the IHCC. Our team worked last week with four seasoned and internationally experienced nickel sulphide geoscientists. The agenda included a thorough review of the IHCC and all the regional norite-hosted nickel sulphide targets identified as a priority for the 2014 season. We look forward to including them again along the path to discovery at Maniitsoq.”

The PEM Survey

The PEM system operates by placing a large loop of insulated wire on the ground through which a precisely-controlled changing current induces magnetic responses from conductors hundreds of metres deep in the ground. It can be used to detect and discriminate between a wide range of conductivities from poor (zinc), to excellent (copper and nickel). Due to its unique transmitted current waveform and its receiver’s measuring system, Crone has developed a step-response transformation of the data which extends this range of detection and discrimination into the extremely high conductance that is seen in nickel exploration. This feature has made the Crone PEM system an important part of the exploration efforts in nickel exploration camps around the world, such as the Raglan camp, Voisey’s Bay, Sudbury, Alaska, Tanzania, Western Australia, and now Greenland.

The Gravity Survey

In addition to the Pulse EM survey, Crone will carry out a gravity survey with a 2 person crew consisting of a gravity operator and a GPS operator with extensive experience in precision gravity surveys. The equipment consists of LaCoste & Romberg model G gravity meters with a reading resolution of 0.01 mGal. The differential GPS (DGPS) system is the Leica – model 1230 Dual Frequency, Dual Constellation (GPS & GLONASS) RTK, rover and Base Station with an accuracy of 1 cm + 1 ppm in separation from the base station to the rover. The crew has extensive worldwide experience and is capable of reducing the data to bouguer mGal values nightly in the field. Gravity surveys measure extremely small variations in the Earth’s gravitational field, which can be used to locate high density material such as nickel sulphide-bearing rock.


Strong EM Targets Have Been Detected Downhole Geophysics at Yepleu and Samapleu Deposit

Posted by on Monday, 24 March, 2014

Sama Completes Downhole Geophysics on Five Drill Holes at Yepleu and Samapleu Deposit (West Africa); Strong EM Targets Have Been Generated

Sama Resources Inc./Ressources Sama Inc. announces the completion of the Downhole Electromagnetic Geophysical (“DHEM”) survey on five (5) holes at the Samapleu and newly discovered Yepleu nickel-copper-palladium Deposits in Côte d’Ivoire, West Africa.

Abitibi Geophysics Inc. from Val d’Or in Canada performed the survey and the interpretation is performed by Mr. Daniel Card, Senior Geophysicist for Southern Geoscience Consultants, Australia.

Three holes were surveyed at the Yepleu deposit, one hole at the Samapleu Main and one hole at the Samapleu Extension 1 deposits.

Preliminary inspection of the data indicate strong Electromagnetic (“EM”) responses on all holes surveyed. Detailed interpretation and modelling is in progress for the following geophysical anomalies:

 
Hole         Location       Response: Depth from surface in meters ("m") 
SM34-570407  Extension 1    - EM anomaly at around 280-320 m 
SM44-525290  Samapleu Main  - EM anomaly at around 150 m 
YE31-637117  Yepleu         - EM anomaly at around 120 m 
YE31-694543  Yepleu         - EM anomaly at around 160 m 
YE23-398223  Yepleu         - EM anomaly at around 40 m

“The survey was performed extremely well by Abitibi Geophysics,” stated Dr. Marc-Antoine Audet, President and CEO. “We look forward to some very good drilling targets from the modelling.” “We are working on this as top priority,” added Mr. Card, Senior Geophysicist for Southern Geoscience Consultants.

The Yepleu discovery is located 18 kilometers (“km”) southwest of the Samapleu nickel-copper-palladium deposits. Regional geological mapping has identified that the geological host of the newly discovered Yepleu nickel-copper-palladium mineralization extends beyond the original 3 km by 600 to 800m to an area as vast as 6 km x 4 km (Refer to News Release dated February 03, 2014).

A total of 18 diamond drilling holes for 3,320m were drilled at the Yepleu discovery testing the large sub-horizontal mineralized layer associated with pyroxenite, gabbro-norite and diorite units been part of the newly identified and described Yacouba Layered Complex (Gouedji et al., submitted to Bulletin de la Société Géologique de France (BSGF), January 24, 2014). Exploration results for all drilled holes at Yepleu will be announced in a subsequent press release.

Exploration Model and Targets

Exploration to date has focused mostly on shallow targets (<150m) at the Samapleu and Yepleu deposits. Sama believes that mineralization at the Samapleu deposits could plunge deeper and could extend laterally as suggested by responses obtained from the Helicopter Electromagnetic survey completed in January 2013 and by the current DHEM survey.

At Yepleu, the Company is chasing embayments or structural features that would have trapped mineralised pyroxenite within the sub-horizontal layered complex assemblage.

The technical information in this release has been reviewed and approved by Dr. Marc-Antoine Audet, P.Geo and President and CEO of Sama, and a ‘qualified person’, as defined by National Instrument 43-101, Standards of Disclosure for Mineral Projects.

For more details, the reader is invited to review Sama’s updated compilation on its website at: http://www.samaresources.com/i/pdf/Sama_Corporate_Presentation.pdf

 

amapleu Project

“Samapleu poly-metallic deposits will give Sama the opportunity to become the first poly-metallic producer in West Africa.”

The Samapleu deposit is comprised of disseminated and semi-massive to massive sulphide mineralization hosted by a mafic-ultramafic intrusion located in the southern border of an early Proterozoic age deformation zone affecting the Archean Charnockitic shield. Mineralization is strata bound within pyroxenite layers of the Samapleu mafic-ultramafic complex.

The disseminated mineralization is typically characterized by fine isolated grains to large granular aggregates of iron, nickel and copper sulphides. Sulphide phases observed so far include pyrrhotite, chalcopyrite, pentlandite and minor pyrite. Pentlandite occurs as inclusions in pyrrhotite. Disseminated sulphide occurs as fine grains of 0.5 to 1 mm in diameter, showing a high ratio of pyrrhotite versus chalcopyrite. Sulphide veinlets and fine filaments are also present. Composite grains of sulphide material are dominant, forming sulphide masses of odd shapes ranging from a few millimeters up to several centimeters in any one dimension.


Coincident Geochemical and Geophysical Data Pinpoints Drill Targets, Greyhound, Nunavut

Posted by on Saturday, 1 March, 2014

Aura Silver Resources Inc. announces the results of a comprehensive report completed by L.E Reed Geophysical Consultant Inc. (“Reed”) which supports, from a geophysical standpoint, drill targets established geochemically by Activation Laboratories Ltd. (Actlabs) Spatiotemporal Geochemical Hydrocarbon (“SGH”) technology for the Aura Lake area as well as the Dingo prospect north-west of Aura Lake, both part of the Greyhound Project, NU.

As reported by Reed, “Correlations between the geochemistry and various geophysical data suggest support for the possible identification of gold and silver deposits at Aura Lake and a gold and copper deposit at Dingo”. This report may be accessed at the Company’s web-site (http://www.aurasilver.com/s/Home.asp) under the section Projects / Canada.

The potential sources of high-grade gold boulders (up to 28 g/t) and high-grade silver (up to 5,300 g/t) have been identified in close proximity to Aura Lake. The gold and copper targets at the Dingo prospect area north-west of Aura Lake are surface showings. New interpretation of geophysical data and SGH has refined the drill targets. This geophysical analysis has identified multiple structures/contacts with the use of three-dimensional inversion imagery of airborne VTEM EM and magnetic responses and ground Induced Polarization and Resistivity data. These structures/contacts at Aura Lake may have provided a pathway for fluids carrying mineralization and are interpreted to support the drill targets originally defined by geochemical analysis.

Robert Boaz CEO and President of Aura Silver states that, “The detailed geophysics analysis undertaken by Reed gives us further comfort that we are zeroing in on the source of high-grade surface gold, silver and copper mineralization. Despite the difficult market for all junior exploration companies we continue to enhance the value of our properties.”

During the fall of 2006, an airborne MEGATEM® geophysical survey was flown on the initial property by Fugro Airborne Surveys Corp. In 2007, further prospecting of MEGATEM anomalies took place. Samples collected in 2007 contained up to 2.4% zinc (Zn), 1.02% copper (Cu), 8.1% lead (Pb), 10g/t gold (Au) and 51 g/t silver (Ag) highlighting the potential for discovery of VMS (volcanogenic massive sulphide) ores.

During 2008, Fugro completed the flying of a GEOTEM® survey over the new Greyhound claim group. Results from this survey were utilized in an on-the-ground field program to complete geological mapping and sampling. Samples prospected during 2008 contained up to 4.1% Cu, 13.4% Zn, 8% Pb, 2,700 g/t Ag and 28g/t Au and to the northeast of Aura Lake a series of boulders contained up to 18.5% Zn and 9.2% Cu.

In late 2009, a high precision VTEM® helicopter borne electro-magnetic survey was completed.


The renewed Interest in Pecors Magnetic Anomaly-Serpent River Property Near Elliot Lake, Ontario

Posted by on Friday, 21 February, 2014

International Montoro Resources Inc. – The Serpent River Property, Elliot Lake, Ontario claims consist of 10 mining claims (115 units) covering approximately 1,840 hectares located in Gaiashk & Joubin Townships. Recent renewed interest has been shown in the 3 upper northwest claims known as the Pecors Anomaly. Click following for maps/regional geophysical overview http://ow.ly/tNTbz.

Montoro congratulates Kelly Strong, V.P. of Ontario and UK Operations -Vale, in the recent startup of the Totten Mine (Totten lies 40 km to the west of Sudbury and approx. 50 km from Pecors). This is Vale’s sixth operating mine in the Sudbury Basin. A polymetallic orebody with good nickel and copper grades as well as precious metals. Click following for the complete story: http://ow.ly/tLq2T. (See page 1 & 19-34 re the Totten Mine and page 15 re the KGHM Victoria Mine Projects)

The Uranium and Rare Earths discovered in the southwest portion at Serpent River may prove to be a sideshow to another deposit type. In a 2009 summary of the Ontario Geological Survey field work, a strong geophysical anomaly on the claims that was previously thought to be caused by an iron formation was reexamined. The new interpretation on the Pecors anomaly concludes it may be the result of contact style nickel-copper-PGE mineralization similar to that found to the east at Sudbury. Sediment sampling from Pecors Lake has shown high levels of nickel and chromium, lending further weight to this analysis. The total field magnetic anomaly strikes northwesterly and is about 15 km long and about 4 km wide.

In its news release dated September 12, 2013, Pele Mountain reports the economic review concludes that the recent increase in mineral resources extends mine life and improves project economics. While this improvement is offset by a reduction in rare earth price forecasts, the net result demonstrates that Eco Ridge economics remain positive.

Int. Montoro is also seeking interested parties in continuing the development of the Serpent River southern portion of its rare earth and uranium property adjoining Pele Mountain’s claims east of Eco Ridge.


Geophysical Program at Mary March in Newfoundland

Posted by on Monday, 10 February, 2014

Canstar Resources (Canstar)  announces the commencement of a borehole electromagnetic survey (“BHEM”) at its Joint Ventured Mary March Project, located near Buchans Junction, Newfoundland. The survey will test for the continuation of the massive sulphide mineralization and thick stockwork mineralized zone encountered in its fall 2013 drilling program (see Company’s press release dated January 21(st) , 2014).

Danniel Oosterman, President and CEO, remarks “With the completion of a successful drilling program that intercepted different styles and widths of mineralization, there is now a strong indication from the geology that we are proximal to the volcanic centre where one would expect these types of deposits to form. An off-hole anomaly from this survey would support this hypothesis and generate excellent targets for future drilling programs.”

The drillholes that will be surveyed cover the two primary areas of the project, Nancy April and Mary March, which have returned significant mineralization and strong indications of a sizeable, long-lived, hydrothermal system. The fall 2013 drilling program successfully proved that both the Mary March mineralization and the Nancy April mineralization extend at least in one direction, with a possibility for further extension in a number of directions.

The design of the survey, which involves loop-wire configurations through which an electric current is charged, has been tailored to suit massive sulphide and stockwork mineralization of this type. Geophysical anomalies in these areas would represent very high priority targets for future exploration on the property.

Discovery holes drilled by Phelps Dodge in 1999 and 2000 produced some of the highest grade base and precious metal intersections ever achieved in the area outside the Buchans mine. The Buchans mine produced 16.2 million tonnes averaging 14.50 per cent Zn, 7.56 per cent Pb, 1.33 per cent Cu, 126 grams per tonne (g/t) Ag and 1.37 g/t Au over its 56-year mine life. By comparison, the discovery holes drilled at Mary March by Phelps ran 10.33% Zn, 118.1g/t Ag, 1.62% Pb, 4.1 g/t Au, 0.66% Cu over 9.23 m; 16.8% Zn, 660 g/t Ag, 12.2 g/t Au, 5.44% Pb, 0.18% Cu over 0.91m; and 3.02% Zn, 1.08% Pb, 72.4 g/t Ag, 0.13% Cu, over 20.6m.

The drill program completed in January 2013 yielded sulphide mineralization containing significant values in copper, lead, zinc, gold, and silver was encountered in 4 of the 8 holes completed. Values were generally lower and over lesser core lengths than in the original drill program conducted over ten years ago


IP data analysis at copper-gold project in Mongolia

Posted by on Monday, 10 February, 2014

Kincora Copper Limited  provides an overview on an internal interpretations of last years exploration programme at Kincora’s flagship Bronze Fox license (Oyu Tolgoi South Gobi porphyry copper belt in southeast Mongolia) having integrated them with previous geology and geophysical results. This follows the recent receipt of positive findings from three independent consultants, further reinforcing an independent groups’ technical review late 2012, advancing and refining multiple bulk tonnage copper porphyry targets.

Some of the Key findings include:

  • Previous results coincident with lower priority Induced Polarization (IP) chargeability anomalies supporting IP being an effective exploration tool
  • Multiple large-scale copper porphyry targets with favourable geology and geophysics drill ready supporting the possibility of bulk tonnage ore mineralization in “finger type” porphyries similar to Oyu Tolgoi or Northparkes in New South Wales
  • Happy Geo prospect has emerged as an attractive, earlier stage, at or near surface follow up exploration target, plus the potential for porphyry targets at depth

 

 

 

 

 

 

 

 

Commenting on today’s announcement, Sam Spring, President and CEO of Kincora, said:

“Internally we are very pleased because drilling in late 2012 was extremely encouraging with localized higher grade, for example over 4% copper in our last hole, and broad lower grade intersections, including at least 800m @ +0.40% CuEq, with 37m @ +1% CuEq, in an earlier hole. Our 2013 field season deployed some of the same wide ranging and detailed exploration techniques used at Oyu Tolgoi to significantly increase the confidence in high priority, and large scale targets that demonstrated exceptional corresponding prospectivity. Last years’ activities, independent consultants analysis and discussions with various industry groups have assisted to “explain” previous results, convincingly prove a fertility signature for copper porphyries and in de-risking multiple drill ready targets.

Considering the size of the anomalies and advance stage of target areas, two key attractions and relatively unique characteristics of Bronze Fox, successful proof of concept activities in 2014 could provide visibility of significant copper-gold resource potential of Oyu Tolgoi or finger style copper porphyries. While earlier stage, the Happy Geo prospect has too emerged as an attractive exploration target, reinforcing that Bronze Fox continues to look better as more activities are undertaken. Kincora is persisting with additional measures to add shareholder value and is encouraged by initial, and further proposed, reform to the Mongolian mineral sectors legislative environment, amongst other efforts to provide additional advantages to the private sector.”

 

 

 

 

 

 

 

 

 

Copper-gold porphyry targets refined and de-risked

Since 2010, Kincora has undertaken soil geochemistry, Vector IP and some sections of DDIP, ground magnetic surveys, and drilled a further 70 holes inside of the Bronze Fox license area. Drilling has expanded the known mineralization footprint to about 40km2, remaining open, confirming porphyry style of copper-gold resource potential with extensive lower grade intersections from at or near surface and proven to 1,360 metres. Results of the last drilling programme, in late 2012 were extremely encouraging with a number of porphyry intersections confirming the potential for a high-grade deposit (localized +4% Cu in our last hole – F72 – drilled into a new target area based upon then recent IP analysis) with broad lower grade (eg +800m @ +0.40%CuEq, including 37m @ greater than 1% CuEq – F62) intersections.

Previous geology and geophysics supported the potential of a copper-gold resource. Indeed early stage studies had commenced on a potentially small scale near production heap-leach SX-EW operation utilising near surface oxide mineralization, and deeper drilling results at the end of the 2012 confirmed the potential for high-grade copper porphyry mineralization. However, the lack of IP data below 400 metres depth, and only in certain areas, limited the ability to reconcile previous drilling and indications of significant scale hydrothermal fluids that support potential concealed higher grade copper porphyry mineralization. Given the limited zones of outcropping primary mineralization, known regional (block) faulting and target of Oyu Tolgoi (‘OT’) or finger porphyry style copper systems, Induced Polarization, coupled with existing magnetics, has been proven to be an effective exploration tool when integrated with proper geological information and interpretation. The success of similar IP programmes at OT and the technical successes experienced by Kincora in late 2012, with drilling at previous IP anomalies returning alteration, sulfides and copper mineralization (+4% localized copper intersection in F72), adds significant substance to IP analysis particularly given existing geological data available at Bronze Fox, which is one of the most advance copper exploration projects in Mongolia.

OT style mineralization generally features relatively narrow (comparing with North and South American porphyries), long strike orebodies, and good extension to depth. As such, the Search IP system, utilized in the 2013 IP survey, which has penetrated to over 800m to 1000m, was selected as the optimal tool to assist locating the mineralization or alteration zone with disseminated sulfides (which is normal for porphyry mineralization) with good extension to depth which may indicate disseminated pyrite/sulfides channels, and support the possibility of ore mineralization based on the comparison of previous drilling results and the distribution of the IP chargeability anomalies. It is thought that those mineralization or alteration zones with good extension to depth have a better chance to host higher-grade mineralization, and economic orebodies.

At Bronze Fox, the 2013 IP analysis illustrates that prior drilling failed to adequately test most large chargeability high anomalies with previous encountered mineralization coincident with lower priority IP chargeability zones. Prior to the 2013 programme earlier geophysics could not provide an adequate guide for either depth extension potential of identified mineralized zones nor for targets below 400m below surface, with drilling being largely lead from encouraging mineralization encountered in previous core. For example the aforementioned holes, F62 and F72, illustrate the grade of CuEq and IP chargeability co-relationship, which support that high chargeability is coincident with sulfides of mineralization zones. The new IP results coupled with the latest alteration and veining studies have “explained” previous results, particularly the extensive 0.20 to +0.30% copper intersections to date, and lead to a reinterpretation and refinement of targets. In F62, over 800m graded at least 0.4% CuEq with subsequent IP analysis indicating the hole only interested the periphery of a relatively weak anomaly target (noting higher grades, including 37m @ +1%CuEq, were coincident with being within less than 500m from the interpreted IP anomaly zone) and subsequent alteration and veining studies indicate a less prospective portion of the interpreted porphyry system. The application of the 2013 Search IP programme, coupled with existing geology and geophysics, and independent analysis undertaken by Professor Tony Crawford and Plus Minerals (Imants Kavalieris) has advanced and refined target generation.

A number of analogies between the current stage of exploration and results at Bronze Fox and Oyu Tolgoi pre “discovery hole” have emerged after our 2013 field season, including geophysical anomalies remaining largely untested with favourable mineralization coincident nearer surface and lower priority IP targets. At Oyu Tolgoi, previous BHP and Ivanhoe drilling failed to reach the geophysical targets, with a change in exploration approach to test the geophysical and hypogene potential resulting in OTD 150, between previous shallow holes (BHP 9 and BHP 10), being the first ‘deep’ hole and credited as the “discovery hole”.

At Bronze Fox nine drilling target zones have been identified following the latest IP survey results being integrated with geology, soil geochemistry, rock chip assay result, ground magnetic survey and historical drilling results. IP survey results illustrate multiple significant strike (+1-2km) chargeability high anomalies with good extension to depth that may indicate disseminated pyrite/sulfides channels.

Two targets of particular note are:

  • Sophie North – a classical geophysical circular feature ~2km x 3km from an estimated ~300-500m depth to +900m. Previous drilling failed to enter IP target zones but returned anomalous copper and gold mineralisation (holes lost in an alteration zone).
  • Eastern West Kasulu/Leca Pass – Numerous holes close to IP targets have returned favourable grades but have failed to test the target zone. Multiple specific +1-1.5km anomalies targeted for potential drilling with regional scout holes and geology providing favourable results.

Successful “proof of concept” activities at the identified targets, including Sophie North and Eastern West Kasulu/Leca Pass, with economic grade (or high grade) intersections, could support a significant copper ore resource. Collectively there is large-scale copper-gold resource potential which is one of the underlying attractions of Bronze Fox. Previous phases of exploration have been favourable, refined and de-risked target generation, and while there is no certainty of exploration success, numerous drill ready targets have been defined, with few other activities that could meaningfully further de-risk these targets (ex-Happy Geo, discussed further below) based on previous experience at Bronze Fox and other porphyry exploration projects.

Happy Geo prospect

Following the very high and large chargeability anomalies identified by the Search IP surveyed in 2013 and 3D IP undertaken in 2012, a further 68 rock samples were collected in late 2013 from various alteration zones focused around the Happy Geo prospect. This region is a relatively early stage exploration area, activities really only commenced in 2013. Favourable soil and rock chip samples, with good gold anomalies and outcrop, were returned during the 2012 and 2103 field seasons. Plus Minerals’ short wave infra-red (SWIR) spectrometer analysis of the 68 recent samples confirmed zones of argillic, sericitic and and silicification alteration with pyrite coincident with the IP chargeability anomalies. The SWIR analysis indicates alteration maybe related to an underlying porphyry system but further analysis is planned and required to confirm this.

Further integration of data and analysis on this area is ongoing and while early stage, and very different to the more advanced northern targets, it could indicated some additional resource potential besides the known copper potential areas in Sophie North, West Kasulu, Leca Pass etc. Two zones of outcrop, both with at least a 1-1.5km strike, have been identified at Happy Geo with rock chip samples of up to 91g/t gold.

Seismic and airborne geophysics for copper project in southeast Arizona

Posted by on Saturday, 14 December, 2013

Millrock Resources Inc. recently completed a seismic geophysical survey and drilling of a single reverse circulation borehole at its Monsoon copper project in southeast Arizona. The survey results and the drill hole indicate that it is unlikely that a large porphyry copper deposit exists within 500 m of surface. The project was the subject of an option agreement with FQM (Akubra) Inc, formerly Inmet Mining Corporation, a wholly owned subsidiary of First Quantum Minerals Ltd. (“FQML”) whereby FQML may have earned a 70% joint venture interest. FQML has advised Millrock that it will withdraw from the option agreement. Millrock believes there is potential for discovery of a porphyry copper deposit at greater depth and intends to seek a new funding partner to further test the targets developed.

Prior to the recent exploration phase Millrock had carried out property-wide biogeochemical sampling, soil sampling, water well sampling, and airborne ZTEM and magnetic surveys. The work was designed to search for buried porphyry copper deposits along the projected trend of the Safford copper deposits in Laramide-aged rocks that host copper mineralization in the district.

Reprocessing and interpretation of historic seismic data had led Millrock to believe that an upthrown structural block of Laramide-aged rock may be present, and that copper mineralization may exist in the shallow subsurface. A modern 2D seismic reflection survey was carried out to confirm the historic survey in an area where Millrock had discovered polymetallic anomalies in various geochemical surveys. Two lines totaling approximately 17 km were surveyed. Two possible interpretations could be made from the seismic data. One interpretation indicated the favourable Laramide contact was at an approximate depth of 500 m below surface. Another interpretation indicated a depth of approximately 1,000 m.

A vertically-oriented 500 m reverse circulation hole was drilled as a stratigraphic test and to determine the source of the geochemical anomaly. Results of the drilling suggest that an upthrown structural block does exist in the area tested. Tertiary volcanic rock was intersected at only 100 m below surface; a much shallower level than in holes drilled by prior explorers elsewhere on the property. However, the contact with the Laramide aged rocks must lie deeper than 500 m; most likely at an approximate depth of 1,000 m.

The technical information within this document has been reviewed and approved by Gregory A. Beischer, President & CEO of Millrock. Mr. Beischer is a Qualified Person as defined in NI 43-101.

Target: The target at the Monson property is a giant high-grade porphyry copper deposit (± gold and molybdenum). The project is located approximately 50 km (31 mi) south of the Morenci Mine and 50 km (31 mi) southeast of the Safford Mine, both giant porphyry copper deposits actively being mined by Freeport McMoran.

The property is covered by post-mineral Tertiary volcanic rocks or alluvium and remains largely untested for porphyry copper mineralization. Geochemical, geophysical and geologic data, however, suggests potential for the discovery of a buried porphyry copper deposit at Monsoon.

Location and Setting: The Monsoon property is located near Duncan in southeastern Arizona approximately 50 km (31 mi) southeast of Safford, Arizona. Topography varies from moderate to flat. Paved highway 70 passes just east of the property with good access to the property provided by dirt roads.

Geology and Mineralization: The Monsoon property is located southeast of the Safford Mine along the Safford porphyry copper trend as defined by known mineralization at the Safford (Dos Pobres, Lone Star, San Juan and Sanchez), Sol and San Jose porphyry copper properties. Geochemical and geophysical data further defines the Safford trend through the Monsoon property

The project area is covered by post-mineral Tertiary volcanic rocks and alluvium, however geochemical, geophysical and geologic data suggests potential for the presence of a buried porphyry copper deposit. Past drilling is limited to two shallow holes drilled in the 1990′s by Noranda. Neither hole penetrated Laramide-aged basement, drilling only post mineral alluvium. Zones containing anomalous copper and molybdenum values were intersected in both holes. The Laramide-aged geology of the property remains largely unknown and the porphyry copper potential unexplored.


The new MT anomalies near Paulatuk, Northwest Territories

Posted by on Tuesday, 10 December, 2013

Darnley Bay Resources Limited (“Darnley Bay” or the “Company”) announces the discovery of two new large magneto-telluric (MT) anomalies at its 100% owned Darnley Bay Property, located near Paulatuk, Northwest Territories. Like the first MT anomaly – reported (see October 13, 2013 press release), the new anomalies are spatially coincident with previously-discovered gravity anomalies, are considered good to moderate conductive zones and appear to be hosted by prospective Proterozoic rocks. They are located respectively two and twelve kilometres east of the first MT anomaly.

Darnley Bay received the latest 3D inversion results from EMpulse Geophysics Ltd, the geophysical contractor. The new inversions not only used the magnetic field tipper data, but also included static shift analysis to minimise near surface geologic noise and to better image the apparent resistivity distribution at depth (see EMpulse web site for more details http://www.empulse.ca/).

The MT survey was performed in August 2013 and consisted of a total of 73 line-kilometres, with stations every 500 metres, over three different lines (North, South and East). See http://www.darnleybay.com/news/Figure_1.html andhttp://www.darnleybay.com/news/Figure_2.html, 1:250,000-scale plan views, showing the location of the surveyed lines and of the MT anomalies over gravity and magnetic models backgrounds. http://www.darnleybay.com/news/Figure_3.html is a stack of three vertical profiles along the North Line; the two upper profiles show the MT anomalies over a gravity and a magnetic models background; the lower profile show the MT anomalies over a 2D geological model that honours the gravity, the magnetic and the seismic data of this sector. The new 3D-inversion model revealed:

  1. On the North Line, 12 kilometers east of the first anomaly, a 1.5×3.5 kilometres anomaly with a maximum thickness of 800 metres, its center being at elevation -2,000 metres (below sea level), It is considered to be a moderate to good conductive zone with apparent resistivity values ranging from 32 to 8.9 Ohm-m
  2. On the North Line, two kilometres east of the first anomaly, a 1.0 x 2.0 kilometres anomaly with maximum thickness of 600 metres, centered at elevation -1,300 metres with apparent resistivity between 32 Ohm-m and 15.1 Ohm-m
  3. On the South and East Lines, three weaker anomalies (80 to 45 Ohm-m), with dimensions of 1.0×1.0-3.0 kilometres between elevations -1,000 to -2,400 metres.

The extent, depth, conductivity and the geological setting of the three MT anomalies on the North line fit the metallogenic exploration models Darnley Bay is exploring for: either a copper-nickel magmatic model (example: Sudbury in Ontario or Noril’sk in Russia) or an Iron Oxide Copper Gold model (example: Olympic Dam in Australia).

“I am pleased by these latest results,” says Jamie Levy, President of Darnley Bay, “we now see two new conductive magneto-telluric (MT) anomalies, along with our previously announced anomaly, on the North line. In addition, three less conductive MT anomalies have been interpreted on the East and South lines. We believe the north line has identified priority drill targets with favourable geological and geophysical settings.

The Darnley Bay Property covers a total of 456,000 hectares with a series of mineral concessions and prospecting permits obtained from the Inuvialuit Regional Corporation and the Canadian Government. The Property encompasses what is considered one of the largest and strongest coincident regional gravity and magnetic anomalies in the world with dimensions of 80 x 100 kilometers. The regional gravity anomaly has absolute amplitude of 132 mGal (milli-gals), while the magnetism reaches 1,350 nT (nano-teslas). Darnley Bay staff believes the source of this anomaly is a large and deep mafic-ultramafic intrusion, the type underlying other base metal mining camps, with the potential for mineralization being at shallower depth than the main intrusion itself. It is thought that it was formed during the regional Franklin or the Mackenzie magmatic events, both Proterozoic in age (720 million years and 1,270 million years respectively).

Magneto-tellurics is a geophysical method of imaging the Earth’s subsurface by measuring natural variations of electrical and magnetic fields at the Earth’s surface. In the 1990′s, MT was successfully used to locate mineral deposits as deep at 1,750 metres in the Sudbury nickel mining camp. In the last 10 years, the technique has seen many improvements, particularly with the development of modern 3D inversion. In the oil industry, it is now routinely used, in conjunction with seismic, to better define deep drilling targets.

At the Voisey’s Bay nickel mine, magneto-telluric survey data detected the nickel-copper mineralization at depth, with apparent resistivities between 10 and 25 Ohm-m (http://www.cemi.utah.edu/appls/mt/) similar to the range of values of the three MT anomalies detected on the North line last August on Darnley Bay Property. Resistivity from the Darnley Bay MT anomalous zones may decrease once the final processing of additional low frequency data is completed. Readers are cautioned that the similarity of the survey results is not necessarily indicative of mineralization on the Property. The magneto-telluric method only measures variations in resistivity in the earth and MT anomalies can also be caused by variations in resistivity due to large scale variations in lithology, structure, and/or conductivity of disseminated minerals or pore fluids as in sedimentary rocks. However, the fact that all the anomalies detected so far are closely related to gravity anomalies (http://www.darnleybay.com/news/Figure_1.html and http://www.darnleybay.com/news/Figure_2.html) suggests that the MT anomalies could be produced by denser material than the surrounding rocks; metal-rich lithologies and/or alteration zones being possible sources.

Darnley Bay is waiting for more results from EMpulse; particularly the processing and inversion of the extended bandwidth time series (to 1Hz) that should provide information to depth of 3 to 5 kilometres. Darnley Bay is planning to do more detailed MT surveying on each side of the North line, in order to better define the attitude and orientation of the anomalies for an eventual drilling program. Darnley Bay is also planning more MT surveying over other selected areas on the Property.

The 2013 MT survey on the Darnley Bay Property was performed by EMpulse Geophysics Ltd, from Dalmeny, Saskatchewan (http://www.empulse.ca/). The technique used for this survey is Transient Audio-Magneto-Telluric, with proprietary SFERIC II instrumentation and Adaptive Polarization Stacking algorithm. David Goldak, M.Sc. (Physics), President of EMpulse Geophysics, was in charge of the survey in the field and responsible for the 3D-inversion and the data processing. The technical information of this Press Release has been prepared, reviewed and approved by Mr. J. Gauthier, P. Eng., P. Geo., the Qualified Person as defined by National Instrument 43-101.

The Company is very pleased to announce the hiring of Alan King as a senior technical adviser. Mr. King is a geophysicist who most recently served as the Chief Geophysicist for Vale’s global exploration operations. Alan holds a B.Sc. in geology from the University of Toronto and a M.Sc. in geophysics from Macquarie University. Mr. King has worked as a geophysicist in exploration and resource development globally, including in Canada, Australia, and Brazil, since 1976.

Airborne Geophysical Survey Underway at Brahma/Austral Project

Posted by on Wednesday, 18 September, 2013

Condor Resources Inc.announces that MMG Chile Exploration SPA (“MMG”), a subsidiary of MMG Limited, has commenced an airborne geophysical survey over Condor’s Brahma/Austral porphyry copper project in southern Chile.

The survey is being conducted by New-Sense Geophysics Limited and includes airborne radiometrics and magnetometer surveys utilizing a Eurocopter AS350 B3. Approximately 3000 line-kilometres will be flown at 150m line-spacings, and it is anticipated that the survey will be completed before the end of September.

Condor recently signed an agreement giving MMG a 270 day exclusivity period to conduct a mandatory due diligence program at Brahma/Austral, which due diligence includes the airborne survey, and follow up mapping and sampling. If MMG decide to proceed with an option agreement, they will be required to complete cumulative exploration expenditures of US$7 million, and complete a Preliminary Economic Assessment, both within 6 years of execution of the option agreement, in order to earn a 70% interest in Brahma/Austral.

The Brahma/Austral concessions cover some 186 sq km situated southeast of the city of Talca in southern Chile. The project is located on the southern extension of the West Fissure fault system, the continental scale structure which controls most of the large world class copper deposits located within the central Andes of Chile, including the El Teniente mine located 200 km to the north.

Geology/Mineralization:

In 2006, Dr. Richard Culbert discovered a highly anomalous stream sediment sample at a location called Los Boldos Creek. In 2007 Condor geologists, attempting to locate the source of the copper anomaly within the creek, identified and traced float boulders containing finely-disseminated chalcopyrite and covellite in a pervasive quartz-sericite (“phyllic”) altered quartz feldspar porphyry intrusive (QFP) to a tributary of the main creek and then to an outcrop where copper sulphides occur as disseminations, localized stockwork veinlets and fracture coatings. Subsequent prospecting approximately 300 m vertically above this outcrop located additional pervasive-altered and leached QFP in bedrock, with hematite and lesser jarosite occurring as disseminations, in stockwork veinlets and on fracture surfaces within the intrusive. This type of alteration closely resembles the leached capping commonly occurring above most Chilean porphyry copper deposits. Abundant finely disseminated chalcopyrite, covellite and pyrite occur at the base of the intensely-altered system.


Zanthus Ni-Cu Project in Australia

Posted by on Monday, 19 August, 2013

The Zanthus Ni-Cu Project is located approximately 60km along strike from the Sirius Resources’  Nova-Bollinger Ni-Cu discovery in the emerging Fraser Range Nickel Province, Western Australia. The project covers an area of 367km2. Gravity data was gathered over an area of 137km2 of the potential gneiss units interpreted as being similar to those that host “the Eye” mafic – ultramafic intrusive that contains the Nova-Bollinger deposit.

Buxton commenced a VTEM survey over the Zanthus (E28/1959) Project in August 2013. The survey covered 145km² and was flown at 250m spacing using the VTEM max system. If conductors indicating potential sulphide bodies are encountered, additional infill lines will be considered.

The survey area is focused on possible mafic‐ultramafic intrusive bodies identified in the recent gravity survey. From the 15 targets identified from the gravity survey, 3 have been designated as high priority (priority 1) targets and include.

  • Z‐01: Very strong remanent magnetisation with coincident gravity high located on fold axis of dome structure and margin of a large intrusive body. Surface copper geochemistry high 112ppm.
  • Z‐02: Magnetic features including discrete positive anomalies and remanent magnetisation. Localised gravity high located along fold axis of large dome‐type structure on the margin of intrusive body.
  • Z‐06: Moderate to weak magnetic remanence on the margin of intrusive body. Located along regional shear zone with both broader and discrete gravity highs. Surface nickel geochemistry high 95 ppm.

Once preliminary results are received, a first pass geochemistry program will commence.

Initial Drill Program Successfully Extends Blackbird and Black Horse Chromite Zones in Ring of Fire

Posted by on Tuesday, 23 July, 2013

Bold Ventures Inc. and KWG Resources Inc. announce jointly the following drilling results from the initial diamond drill program on their Koper Lake Joint Venture in the Ring of Fire (ROF) Northeastern Ontario, which is under option from Fancamp Exploration Ltd. (FNC) (see Bold’s press release dated January 7 2013). In turn KWG has optioned the property from Bold on terms that are described in a Bold press release dated March 4, 2013.

Drilling with three drills commenced early in March 2013. The drilling was briefly halted in early April 2013 pending the issuance of an Exploration Permit by the Ontario Ministry of Northern Development and Mines pursuant to the revised Ontario Mining Act.

In late May while drilling the last two holes of the program a forest fire, in close proximity, threatened the drill camp which housed the project personnel. All personnel were evacuated from the area until the fire was brought under control. As a result, the program budget was exhausted and the last two holes were stopped short of the target depth. Casing for holes FNCB-13-35 and FNCB-13-37 was left in place and capped for access at a later date.

During the program a total of ten holes (FNCA-13-29 and 29W1, and FNCB-13-30 to 37) totaling 6040.8 metres were drilled.

Drill Results Nickel/Copper Massive Sulphide Potential

Hole FNCA1329 was collared in the northwest corner of the Fancamp property to provide a platform for down hole geophysical surveying in a northerly oriented ultramafic conduit feeding the northeast-southwest striking Ring of Fire (ROF) ultramafic complex. A similar north-south striking conduit further west hosts the Eagle’s Nest copper-nickel base metal deposit previously discovered by Noront Resources Ltd. in 2007. The hole encountered poor ground conditions and had to be halted before reaching its target depth and was wedged off at 1015 metres. This wedge hole, FNCA-13-29W1, was advanced as far as 1051 metres when the hole was stopped and surveyed with a down-hole electro-magnetic system. Results did not warrant any further drilling from this platform.

Drill Results Chromite

Holes FNCB-13-30 to 37 were drilled to further explore the Black Horse chromite mineralization previously discovered by FNC (see Fancamp’s press release dated May 24th, 2011) as well as to test for the eastern extension of the Blackbird chromite mineralization located on the adjoining Noront Resources Ltd. claims (see Noront’s press release dated March 20th, 2012). The holes were drilled to test an approximate 800 metre strike length of the Blackbird – Black Horse horizon on the western most claim of the four-claim Koper Lake Property. The program was successful in confirming that chromite mineralization does exist within the Koper Lake property directly to the east of the adjoining Blackbird deposit owned by Noront Resources and also in extending the Black Horse mineralization outwards from previously drilled (2010) holes FN1025 and FN1026. Further drilling is required in order to understand the spatial relationship of the Blackbird and Black Horse horizons and the continuity and orientation of those mineralized zones.

Highlights

Holes FNCB1330, 32 and 33 were drilled to test the downplunge continuity of chromite mineralization delineated on the adjacent Noront Resources property.

Hole FNCB1330 intersected 45.76 metres of chromite mineralization from 655.5 to 701.26 metres consisting of disseminated, heavily disseminated, semi-massive and massive chromite. This intercept contains two intervals dominated by massive chromite: from 664.67 to 677.65 metres (12.98 metres) and from 685.67 to 696.32 metres (10.65 metres). The weighted average percentage of Cr2O3 of these two intervals is 26.44% and 31.89% respectively.

Hole FNCB1332 encountered a thin band of massive chromite between 656.13 and 659.0 metres. The intercept assayed 34.48% Cr2O3 over 2.87 metres.

Hole FNCB1333 intercepted two intervals dominated by massive chromite, from 695.48 to 721.07 metres (25.59 metres) and from 753.0 to 813.26 metres (60.26 metres). The weighted average percentage of Cr2O3 of these two intervals was 27.98% and 28.31% respectively. These zones were encountered within a broader low-grade horizon of chromite mineralization.

Diamond drill holes FNCB1334 and 36 from the same collar location were drilled to test a shallow gravity anomaly which was interpreted to possibly represent the updip extension of the Black Horse mineralization.

Hole FNCB1334 drilled at -68 degrees encountered disseminated to layered chromite between 127.44 and 144.14. Assay results included 5.66 metres grading 18.51% Cr2O3 (from 137.58 metres to 143.24 metres).

Hole FNCB1336 drilled at -45 degrees intersected massive to heavily disseminated chromite between 126.44 and 132.84 metres. Assay results included 4.01 metres grading 18.56% Cr2O3 (from 126.44 metres to 1304.5 metres)

Holes FNC1335 and 37 were stopped short of target depth. Future plans will include continuing those holes to their completion.


TEM Geophysics for Maniitsoq Ni-Cu-Co & PGE Sulphide Project in Greenland

Posted by on Friday, 12 July, 2013

North American Nickel Inc. announces that diamond drilling has begun on its 100% owned Maniitsoq project. A minimum of 3,000 meters is planned and it will focus on testing high priority VTEM electromagnetic (EM) anomalies defined within the 70 km-long Greenland Norite Belt and on following up the multiple high-grade nickel sulphide intersections drilled by NAN last year at Imiak Hill and the Spotty Hill discovery.

NAN CEO Rick Mark states: “The full team is now in Greenland and helicopter supported fieldwork, including channel sampling and ground truthing of anomalies is underway. The drill team has also begun its work and is supported by a second helicopter. The plan is flexible allowing us to stay in areas that produce core of interest to the geologists on site. COO Neil Richardson is leading the crew. We are planning to ship core samples weekly out of Maniitsoq. It will be an exciting summer for all of us.”

The drilling will be done with a helicopter-portable drill contracted from Westcore Drilling Ltd. A borehole pulse EM (BHEM) system, supplied and operated by Crone Geophysics & Exploration Ltd., is on site. It is anticipated that most holes will be surveyed with the BHEM system, which greatly increases the search radius of the holes, allowing geologists to target follow-up holes more precisely. The system can also be used for surface surveying in the event that an EM anomaly requires more detailing prior to drilling.

Throughout the summer field crews will continue to map, prospect, sample and evaluate VTEM anomalies on surface. Approximately 660 line-km of VTEM helicopter time domain EM surveying is planned for later in the season. The survey will be flown by Geotech Ltd. and will cover several areas of interest outside the main norite belt.

Montoso zone in Mexico drilling intersects pyrite-rich porphyry alteration containing broad intervals enriched in silver

Posted by on Tuesday, 9 July, 2013

Westminster Resources Ltd. has compiled results from five core holes drilled on the Montoso Target of the Company’s Cumbral-San Bartolo project in Sonora, Mexico. This portion of Westminster’s concessions is being explored through an earn-in Option Agreement with Capstone Mining Corp. (“Capstone”) who have 49% interest in the project having funded $3.3 million to date on exploration. A further contiguous 9,615 hectares of new mineral concessions have been added to the project.

A total of 4,163 meters was drilled in the five holes to test a complex geophysical anomaly system coincident with variably anomalous soil geochemistry and extensive leached gossanous zones. The geophysical surveys produced strong IP chargeability/resistivity responses associated with both high and low magnetic anomalies. The holes were designed to test various gradations in IP response intensity. All holes were drilled on angled (not vertical) projections. This drilling was a portion of the second phase of the project’s exploration with Capstone which also included alteration mapping, prospecting, soil geochemical sampling and geological mapping.

All holes encountered abundant pyrite as disseminations, on fractures and in veinlets in intrusive host rocks (granodiorite, feldspar porphyry, igneous breccia and magnetic mafic intrusive) which exhibit weak to moderate porphyry-related alteration (potassic-phyllic) and sparse veining to minor sheeted vein and stockwork development (“B and D veins”) occasionally containing molybdenite. The nature of the metal content, and geologic interpretation of the core suggests that this first phase of drilling at the Montoso Zone has encountered a pyritic peripheral silver-enriched halo component of a laterally extensive porphyry hydrothermal system.

The Montoso Zone drilling showing elevated results. Holes 1, 2 and 5 tested the central and south high chargeability and magnetic high and low patterns while holes 3 and 4 were designed to test the northern edge of the Montoso target and a blanket-like conductivity anomaly extending further to the north.

Mineralization is characterized by high-grade, gold-copper-silver veins, breccias associated with porphyry deposit-style systems and hematite-magnetite-sericitized zones and structures containing copper-gold-silver mineralization in an IOCG / Porphyry setting.

Recent airborne VTEM and MAG geophysical survey results for the newly-discovered Cumbral-San Bartolo area identified district-scale alteration and magnetic highs and lows associated with regional structures and intrusive emplacements. Completed ground magnetic highs and lows associated with regional structures and intrusive emplacements. Completed ground magnetic and IP geophysical surveys confirmed airborne anomalous patterns and mapping identified surface mineralization associated with a large hydrothermal system.

Completed aggressive exploration in 2012 included expanded 3D-IP and ground MAG coverage (219 Line kilometers), soil sampling (5,000 samples), mineralization mapping and diamond drilling (7 holes, 1,641 meters). The new 3D-IP chargeability survey identified the 1 X 1-1/2 kilometer high chargeability Montoso target and numerous other copper-silver-gold mineralized zones. 2013 drilling at Montoso is directed at this large porphyry system.


Magnetic and IP surveys for copper-gold porphyry target in BC

Posted by on Thursday, 20 June, 2013

COLORADO RESOURCES LTD. reports the results of ground magnetic geophysical surveys recently completed and also announce the start of a 5,000 m drill program on its 100% owned North ROK Property (Porphyry copper-gold) located 15 kms northwest of Imperial Metals Red Chris Mine in NW British Columbia.

As previously reported in news release dated June 12, 2013 Colorado discovered a new Induced Polarization (I.P) chargeability anomaly that is 1 km north of the discovery drillhole in an area of limited outcrop. Preliminary modeling of the recently completed geophysics indicates that this new I.P chargeability anomaly measures 500-800 m wide and 1400 m long. Ground magnetic surveys conducted over the same area revealed two anomalies flanking the I.P chargeability anomaly and one anomaly in the core of the I.P anomaly. The magnetic anomalies flanking the I.P anomaly measure approximately 300 m by 750 and 200 m by 700 m; the magnetic anomaly in the core of the I.P chargeability anomaly measures approximately 500 m by 700 m. See map attached (to view, visit the following link:http://media3.marketwire.com/docs/Colorado_North_ROK.pdfand Company’s website www.coloradoresources.com for details.

The Company is encouraged that these new coincident I.P and magnetic anomalies appear to have a similar geophysical signature to areas of known mineralization on the Property.

The Company is also pleased to announce that a 5000 m diamond drill program has commenced on the property within the existing permits.

Adam Travis, the Company’s President and CEO stated “I’m very pleased with the progress our technical team has made on our North ROK property to not only fine tune our next phase of drilling but to also advance other exploration targets on our claims. I look forward to a very exciting next round of drilling.”
