CAVAN VENTURES INC.  announces it has exposed graphite-rich zones as a result of trenching on its 100%-owned Buckingham graphite property, located adjacent to the historic Walker Graphite Mine in Buckingham Township, Quebec. Graphite-rich zones were exposed in six trenches, and channel samples were collected from two trenches over a combined distance of 59.5 meters. Graphite-rich outcrops at the same location as one of the trenches assayed at 21.7% C.

Peter Swistak, President of Cavan states, “We are extremely pleased that many of our airborne EM anomalies identified last year are now confirmed as graphite mineralization. Our ground geophysics was able to confirm the anomalies in real-time, which allowed us to quickly expose the mineralization and collect samples for assay. We anticipate highly positive results and intend to return for further exploration in the coming weeks.”

In May the Company engaged Magnor Exploration Inc. (La Baie, QC) to conduct a short exploration work program. Ground-based geophysics was used to ground-truth airborne EM anomalies identified last year using the PhiSpy portable TDEM system. PhiSpy generates real-time EM profiles of the area being surveyed, and can detect buried conductors to approximately 10m depth. Dube & Desaulniers Geoscience (Ottawa, ON) was engaged to collect 3.3 line-km of survey data over priority airborne EM anomalies using the PhiSpy system. The real-time interpretation of TDEM data allowed the Company to execute trenching on several high priority targets.

A total of six trenches ranging from four to 48 meters in length and two meters in width were completed. Trench 22C was cut for 24 meters in a northwest direction, with a second perpendicular trench cut at its southeast end for 20.5 meters. Graphite-rich zones were exposed in both directions, and channel samples were collected over most of both trench lengths for a total of 33.9 meters. Mineralization at Trench 22C is still open to the north, with some visible flakes in the trench up to one centimeter in diameter. A rock grab sample assayed previously from this location returned 21.7% C (see news release, July 8, 2013). Trench #1 was cut in a west-northwest direction, with visible graphite channel-sampled over 25.6 meters. Because of the rich nature of the mineralization, these samples and those from Trench 22C were immediately shipped for assay.

A new graphite zone was also discovered roughly 150 meters east of Trench 22C, where graphite-rich veinlets in granitic-pegmatitic rocks contain graphite flakes over 5 mm in diameter. Additionally, an airborne anomaly approximately 400 meters north of the main set of conductors was confirmed by PhiSpy, but the program ended before this new target could be tested through trenching.


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.


Geophysics indicates conductive core at Mary March in Central Newfoundland

Posted by on Wednesday, 26 March, 2014

Canstar Resources  provides an update on the current exploration activity for its Mary March Project, located near Buchan’s Junction in Central Newfoundland.
The Company’s recent borehole geophysical program conducted on holes drilled during 2013 has provided results that distinguish a high priority drill target near the Mary March massive sulphide zone. All of the holes surveyed clearly point to a more conductive zone downdip and to the east of holes MM13-29 and MM13-30, suggesting the mineralization is open for expansion in these directions.

 

 

 

 

 

 

 

 

 

————————————————————————————————————

The Mary March zone is the initial discovery area drilled by Phelps Dodge in 1999 where they encountered impressive grades of 10.1% Zn, 1.68% Pb, 0.64% Cu, 122.1 grams per tonne (g/t) Ag, and 4.2 g/t Au over 9.63 meters. The drilling completed by the Company in the Mary March area successfully added to these results, encountering massive sulphide zones with two separate holes. In drillhole MM13-30, 11.6 meters of mineralization containing 3.6% Zn, 0.1% Cu, 0.8% Pb, 25 g/t Ag, and 1.5 g/t Au; including a 3.6-meter high-grade zone containing 7.5% Zn, 0.04% Cu, 1.37% Pb, 26.1 g/t Ag, and 1.7 g/t Au, and extended the Mary March Zone to depth. In MM13-29, 5.0 meters of mineralization was encountered, containing 4.82% Zn, 0.38% Cu, 1.04% Pb, 71.3 g/t Ag, and 1.8 g/t Au, including 3.5 meters of 6.21% Zn, 0.13% Cu, 1.42% Pb, 82.8 g/t Ag, and 1.9 g/t Au (see Company Press Release dated January 21, 2014).
Results for surveys completed for holes in the Nancy April area, which is located approximately 500 meters southwest of the Mary March zone require more data and investigation, remaining relatively underexplored compared to the Mary March zone.

“This is exciting news for our shareholders and for the Mary March project,” stated Danniel Oosterman, President and CEO of Canstar. “In an area where mineralization is known to give weak responses, we are encouraged to find such an obvious anomaly offhole to known mineralization. Needless to say the company regards this as a high priority target for its next drilling program.”


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.


Exploration on Éléonore Gold project, Québec

Posted by on Friday, 14 March, 2014

Midland Exploration Inc.  reports the beginning of its exploration activity on its 100% owned James Bay Éléonore Gold project located in James Bay, Québec. The first phase of the 2014 exploration program consists of a helicopter airborne magnetic geophysical survey over the Éléonore Centre property.

The Eléonore project, which encompasses the Éléonore Centre and West properties, is constituted of a total of 247 claims covering 128 square kilometres, and is located approximately 30 kilometres southwest from and in a geological environment similar to Goldcorp Inc.’s Éléonore deposit. This world-class gold deposit contains reserves of 4.03 Moz Au (proven and probable categories), combined measured and indicated resources of 4.84 Moz Au and inferred resources estimated at 4.10 Moz Au. (Source: Goldcorp press release dated February 13, 2014).

Prospecting conducted by Midland from 2009 to 2013 on the Éléonore Centre property identified the presence of several gold showings associated with quartz-tourmaline pyrite bearing veinlets occurring in sheared metasediments, as well as mafic and felsic metavolcanics which returned up to 18.8 g/t Au. These results strongly suggest that an auriferous hydrothermal system is present on the property by a strong abundance of quartz-tourmaline veins over a plurimetric area. In addition, the 2013 ground induced polarisation (“IP”) survey identified many north-south trending IP anomalies and several remain unexplained. The 2011 soil geochemistry survey permitted to delineate a series of As-Cu-Sb anomalies clustered along a north-south-trending axis. Finally, a series of parallel northeast trending AeroTEM II conductors were outlined by the 2010 airborne geophysical survey which targeted sulfide bearing Éléonore-type sediments on the northern part of the Éléonore Centre property. Some of these conductors coincide with uncovered gold-bearing disseminated to semi-massive sulfides zones identified by Midland and several EM anomalies still remain unexplained.

A high definition airborne magnetic survey covering the Éléonore Centre property was just completed, including the area covered by the 2013 IP survey. The results and interpretation of this survey, totalizing 386 linear kilometres, are pending. Furthermore, preparation for the upcoming 2014 summer exploration program on the Éléonore Centre property currently underway.

Location:

  • The Eleonore property is located about 450 kilometres north of the town of Matagami, in the Opinaca Reservoir area, James Bay, Quebec.

Property:

  • The Eleonore property consists of two claim blocks (Centre and West). The Centre Block consists of 121 claims covering a surface area of about 63 square kilometres, whereas the West Block consists of 109 claims covering about 57 square kilometres. The two blocks are located about 30 kilometres southwest of the Roberto deposit on the Eleonore property held by Goldcorp, where measured and indicated resources are estimated at 3.15 million ounces of gold and inferred resources at 6.25 million ounces of gold.

Highlights:

  • Covers a major N-S-trending structure between metasedimentary rocks and metavolcanic rocks interpreted as the extension of the structure occurring near the Eleonore gold deposit.
  • Prospecting work has uncovered many new gold showings associated with metasedimentary rocks (conglomerates and greywackes):
    • Golden Gun showing: 18.8 g/t Au, 13.6 g/t Au, 0.76 g/t Au
    • Golden Gun West showing : 1.69 g/t Au
    • Aston Martin showing : 1.63 g/t Au
    • Gold Finger showing: 1.01 g/t Au, 0.82 g/t Au
    • Golden Eye showing: 1.90 g/t Au, 0.90 g/t Au
    • Casino showing: 0.76 g/t Au, 0.64 g/t Au
  • Located along a regional metamorphic gradient, typical of the contact between the La Grande and Opinaca groups.
  • New soil (humus) geochemistry anomalies identified in the south part of the Eleonore Centre Block.

Recent investigations of geophysics abilities in aquifer mapping and resource evaluation

Posted by on Thursday, 13 March, 2014

Buried beneath the glaciated terrain, valleys filled with coarse-grained permeable sediments  potentially are great sources of fresh ground water. During the last several years Geological Survey of Canada has been investigating geophysical methods potential, particularly airborne electromagntics, for mapping and resource evaluation of buried valleys.   Spiritwood valley aquifer in southern Manitoba has been chosen for the investigations. Heliborne AeroTEM, VTEM, fixed-wing TEMPEST and MULTIPULSE, ground electrical resistivity and time-domain methods, seismic reflection and borehole data have been involved into the complex analysis. Recently collected ground TEM data for Spiritwood and the report (G.A. Oldenborger and K. Brewer, 2014) has been released: http://geoscan.nrcan.gc.ca/starweb/geoscan/servlet.starweb?path=geoscan/fulle.web&search1=R=293700.

Recent Airborne EM Survey close to Albany project

Posted by on Wednesday, 12 March, 2014

Xmet Inc. has successfully completed a Versatile Time Domain Electromagnetic Surveying (“VTEM”) survey, comprising 437 line kilometres, over 20,000 acres of recently staked 100% owned Xmet claims on its Blackflake project.
Three electromagnetic (“EM”) bedrock targets were delineated during the latest survey, including a more detailed survey over the Prime Target discovered and announced in Xmet’s December 12th, 2013 news release. Geotech, who flew the survey and assisted in interpreting the results, have concluded that all three of the anomalies extend into the bedrock beneath overburden and limestone cover.
“A tightly spaced VTEM grid survey was flown over our Prime Target in order to obtain higher resolution over the original TDEM anomaly which was originally defined over a length of 1500 meters,” said Alexander Stewart, Chairman and CEO of Xmet Inc. He continued by saying, “VTEM technology provided much deeper penetration than the TDEM survey flown over the Prime Target in late 2013. With this latest round, the conductivity and the size of the Prime Target is confirmed. The Prime Target is defined by an electromagnetic anomaly in bedrock with an associated magnetic low. The target is geologically constrained between two major diabase dykes. Two new bedrock conductors were also discovered which have similar geophysical characteristics. We are very excited about the potential of these targets, and with our ground permits now in place we are getting closer to drilling these targets.
Xmet’s Blackflake Project comprises over 29,000 acres of 100% owned claims approximately 60km to the northwest of Hearst, Ontario and is adjacent to Zenyatta’s Hydrothermal Graphite Deposit. Xmet has now conducted three airborne electromagnetic surveys, VTEM and TDEM, which discovered multiple electromagnetic conductors making the targets highly prospective for further exploration. Xmet has developed an excellent working relationship with the Constance Lake First Nation, with whom the company signed an ongoing Exploration Agreement.


Exploration drilling for gold initiated by airborne geophysics results in Ghana

Posted by on Friday, 14 February, 2014

Asante Gold Corporation  announces final results and interpretation of the exploration drilling completed to date on the Fahiakoba gold concession in Ghana.

Drill holes were spotted to test sections of airborne geophysical (MAG/VTEM) and ground auger soil geochemical anomalies. Initial drill holes were spaced from 400m to over 1km apart and later tightened to 100m step-outs where gold mineralization was noted. A total of 30 drill holes were completed in two phases, for 4985 m. A collar map is available at:http://www.goknet.net/Asante/FAHcollarsNRJan20.pdf.

Geotech conductivity depth inversion

With the exception of four significant gold intersections (to 0.50 m @ 295 g/t Au), initial sampling results were low. VTEM conductors correspond with favourable graphitic shear zones in meta-greywacke or regional scale graphitic meta-phyllite/argillite units. Weak gold anomalies in core from saprolite have generally accounted for the anomalous auger soil geochemical targets tested in the program.

However, wide zones of moderate to strongly quartz veined meta-greywacke, and carbonate alteration were noted in the program. These zones correspond with elevated to locally significant gold values, as noted in the table below, and are considered high priority targets for additional drilling.

Further drilling is also required along the trend to the NE of Perseus Mining Ltd’s discovery hole NSRC010 located ~1 km south of the Asante Fahiakoba concession boundary and which yielded 30m at 2.2 g/t Au, including 4m at 9.0 g/t Au (Perseus Quarterly Report, December 30, 2012 – true width unspecified).

 

Property Geology

The property is underlain by favourable Birimian meta-sediments, with more than 70% of the Fahiakoba concession covered by transported alluvial material. No modern exploration or drilling has taken place to date. Recent airborne geophysical surveys have outlined some 20 km of strong NE trending shear and fold zones, some of which have associated VTEM conductors. These type of structural targets at Perseus and elsewhere in Ghana host significant gold deposits and will be the target of our ongoing exploration efforts. Anomalous gold values have been noted in a pit with quartz stockwork in granite that is associated with one of the airborne geophysical targets. Phase 1 auger drilling to test below the alluvial cover has been completed with anomalous gold trends identified.


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


Planned airborne geophysical survey looking for an economic graphite deposit at Blackflake property

Posted by on Monday, 10 February, 2014

Xmet Inc. announces that it has engaged Aeroquest International to complete a new round of Versatile Time Domain Electromagnetic (“VTEM”) and Magnetic Gradiometer Survey on its newly acquired 20,000 acres of 100% owned claims which expanded Blackflake’s total area to 29,400 acres. The airborne survey will begin in the next few days.

“This will be our third round of EM aerial surveys and with the exploration success Xmet achieved with its first two EM surveys, we are excited about the potential for this next round of VTEM,” said Xmet’s Chairman and CEO Alexander Stewart.

He continued by saying, “Our primary objective remains to drill test our prime anomaly, disclosed in our news release of December 12, 2013, for which permits for ground geophysics and drilling are expected to be received this month. However this newly acquired land and the further upside potential that the VTEM can deliver is equally exciting.”

Embedded in this news release is a MAP depicting Blackflake’s Eastern Claim Block. As per the map’s legend, the yellow portion within Xmet’s claim block denotes Xmet’s land package prior to January 30th, 2014 News Release and the horizontal grid lines within Xmet’s claim block denotes the 20,000 acres of new claims staked along with the area that will be flown in this round of VTEM.

To view the map accompanying this press release please click on the following link: http://media3.marketwire.com/docs/XME0204.pdf

Bill Yeomans, P. Geo, states, “Given the highly conductive nature of graphite deposits, VTEM is a very effective method for locating potential graphite and massive sulphide type deposits. The new VTEM survey, which will cover approximately 473 line kilometres, is excellent for locating conductive anomalies as well as for identifying lateral and vertical variations in resistivity.”

Drilling and Discovery Update at the Miller Graphite Project with airborne and ground geophysics

Posted by on Friday, 7 February, 2014

Canada Carbon Inc.  provides an update on the advancement of its winter exploration program on the Miller Mine property. Shortly after drilling began in December, it was halted due to the discovery of VN3, a graphite vein that is two metres thick on surface and continuous along strike for five metres. Drilling was re-directed to the VN3 discovery, and real-time electromagnetics (“EM”) were employed to identify new drill targets in the area.

R. Bruce Duncan, CEO & Director of Canada Carbon Inc. stated, “We continue to be pleasantly surprised by the prolific nature of graphite mineralization at Miller. The VN3 discovery is a wide graphite vein at surface over a large airborne EM anomaly, making it a high priority for re-evaluating graphite potential in this area. We continue to investigate this area using real-time ground geophysics to rapidly identify targets for drilling in the second phase of our winter program.”

Previously, the Company announced a minimum 1000-metre drill program of NQ-sized diamond drill holes to test several VTEM anomalies (see news releases, December 3, November 14, 2013). Drill hole DDH13-09 confirmed that the E2 anomaly is associated with a sulfide-rich intersection with minor disseminated graphite. Drill hole DDH13-10 targeted the E3 anomaly and encountered a wide intersection of minor and disseminated graphite in marble. During movement of the drill to the E3 drill site, a graphite-rich vein (VN3) was exposed over two metres in width and along strike for five metres before pinching out.

The VN3 discovery was subjected to drilling with six shallow drill holes targeting the vein at depth and along its projected extension on strike and at depth. The winter campaign encountered bad weather, which slowed down the overall drilling production. A total of 547 metres in nine holes was completed in this phase of the program. Maps showing the DDH location can be found at:

DDH Location Link: www.canadacarbon.com/miller-graphite-project

The most significant results are from the new vein discovery VN3 where drilling in core hole DDH13-15 encountered 48.60% C graphite (Cg) over 1.8 metres, including 63.20% Cg over 0.5 metres. This intersection of graphite occurs 4.6 metres (vertically) beneath the VN3 showing. DDH13-14 intersected a graphite vein grading 50.50% over 0.30 metres in 3.50 interval metre interval grading 6.80% Cg between the surface and the DDH13-15 graphite mineralization. The VN3 showing remains open at depth.

The other hole of interest is hole DDH13-11, which targeted a wollastonite-graphite pod located 22.5 metres southeast of the VN2 showing in the trench area. The hole was successful in extending the mineralization hosting the pod to a depth of 8.19 metres (vertically) beneath the surface showing. Grades similar to other graphite pods (see news release dated November 25, 2013), specifically 8.10% Cg over 2.3 metres including 11.00% Cg over 0.90 metres. The pod southeast of the VN2 showing is suspected to be within the same mineralized corridor that extends to at least 39.3 metres (vertically) beneath the VN2 showing. The mineralized corridor also remains open at depth.

The new vein (VN3) discovery triggered the Company to halt the drill campaign and perform a ground electromagnetic survey over the large VTEM anomaly surrounding target E3 to find the best targets before drilling resumes. Dubé & Desaulniers Geoscience Ltd. (Ottawa) was engaged to perform a ground electromagnetic survey using the PhiSpy system. This portable time-domain EM system enables the detection of conductive rocks at optimum depths of 10 to 20 metres, with the results seen in real time on a display screen. This allows for the strongest anomalies to be immediately identified for further testing.

The PhiSpy survey was performed over a 0.11 square kilometre area centered on VN3 with line spacing between 10-20 metres for a total of 12.7 line kilometres. The survey identified 14 anomalies ranging between 5 and 54 metres in maximum dimension. The widest anomaly was discovered in the vicinity of the E3 target identified previously by Geotech, and the Company is currently working with Geotech to re-interpret their results to include the PhiSpy data. Additional data from the core and surface showings will also be incorporated to identify drill targets in this area.

Winter field work including trenching, beep-mat and TDEM surveys, and prospecting is currently underway on the new PhiSpy anomalies in the VN3 area. Drilling will resume once reinterpretation of all results are complete. Existing targets include the new VN3 showing, the trench area where the VN2 surface mineralization is established to a depth of 39.3 metres, and the E1 anomaly, located 800 metres north of the Miller mine pit. Geophysical maps indicate that E1 lies between two magnetic anomalies that may correspond to a lithologic contact of two geological units having a similar geological context to that of the known Miller mineralization (see news release, November 14, 2013).


THE NEW NICKEL DISCOVERY WITHIN THE FOSSILIK NORITE AT MANIITSOQ PROJECT in GREENLAND

Posted by on Thursday, 26 September, 2013

North American Nickel Inc. announces that the Company has made a new discovery at drill hole MQ-13-018, which is ~9 km south of the Imiak Hill Conduit Complex(IHCC). It intersected three new zones of nickel sulphide; all hosted by the Fossilik intrusion, which is the largest norite body in the Greenland Norite Belt at ~8 sq. km. MQ-13-018 is associated with NAN’s 2012 VTEM conductor P-04.

This new discovery is within a 10km radius from the Imiak Hill Conduit Complex, which the Company believes to be a reasonable distance to truck mineralization to a potential central mining / concentrating complex at, or near, Imiak Hill (see map 1).

NAN CEO, Rick Mark states. “This discovery is only 9 km from our recently announced near solid to solid sulphide intersections at Imiak Hill and Imiak North. It has significant near surface Ni-Cu-Co & PGM mineralization which is disseminated, similar to mineralization at Spotty Hill within the IHCC. The Fossilik norite also contains historical mineralized zones with grades of up to 2.24% Ni and 0.63% Cu. It creates a new area of focus for the company and bolsters our belief that the Maniitsoq conduit system has potential to produce multiple deposits.”

MQ-13-018 HIGHLIGHTS:

  • 32.19m @ 0.59% NI, 0.18% Cu, 0.02% Co, 0.21 g/t PGM (Zone 1)

Including:

  • 4.53m @ 1.06% Ni, 0.23% Cu, 0.04% Co, 0.33 g/t PGM

The mineralization was intersected between 35 and 160 m vertically below surface and it consists mainly of disseminated and blebby sulphides with occasional short intervals of inclusion bearing sulphide. All of the sulphides are hosted in massive melanocratic norite.

The Fossilik intrusion also hosts several historical showings including the Fossilik I and II occurrences:

  • Fossilik II includes historical drill holes with grades of up to 2.24% Ni and 0.63% Cu over a core length of 12.89 metres in drill hole FoIl-1
  • Fossilik I includes historical drill holes with grades of 1.07% Ni and 0.46% Cu over a core length of 25.10 metres in drill hole F-3.

Table 1 below summarizes the assay results for MQ-13-018. All three mineralized zones are hosted in massive, non-foliated, melanocratic norite.

The 2013 exploration program at Maniitsoq has come to an end, with 25 diamond drill holes completed for a total of 4266 metres. The drilling focused on numerous VTEM anomalies and existing Ni – Cu occurrences within the Greenland Norite Belt (GNB). A total of 1541 core samples have been submitted for analysis. All 2011 and 2012 targets (116) have been field checked by NAN geologists with a total of 238 field locations reviewed for mineralization and geological information. A total of 104 rock samples were analyzed and the NAN exploration team collected a total of 150 channel samples over mineralized areas of interest.


EM CONDUCTORS AT BUCKINGHAM GRAPHITE PROPERTY, QUEBEC

Posted by on Wednesday, 25 September, 2013
CAVAN VENTURES INC. announces that airborne geophysics has identified a 1,300 meter-long conductor on its 100%-owned Buckingham graphite property in Quebec. The anomaly is oriented roughly north-south, and is divided by an east-wend trending dyke into a 700-meter long southern segment and 600 meter long northern segment. This conductor coincides very well with a conductor identified in a 1982 government survey, and with graphite mineralization previously reported as having up to 11% C in grab samples. A second significant conductor was also identified that extends to about 300 m in length, and corresponds to an area where prospecting by the Company included a grab sample returned 21.70% C from a schistose paragneiss (see news release, July 8, 2013). West of this smaller conductor, five significant conductive anomalies or groups of anomalies were detected of lesser length extents, but with a response that is characteristic of strong conductors such as graphite or sulfide mineralization.
These excellent results support the potential of the Buckingham property to host significant graphite deposits. The Company will shortly undertake a second phase of exploration that will comprise a surface geophysical survey to resolve the airborne anomalies, followed by a phase of stripping and trenching and later the investigation at depth by diamond drilling of what is discovered on surface.
The helicopter-borne survey covered about 50% of the area of the property. Prospectair (Gatineau, QC) carried out the survey, with Magnor Exploration Inc. (La Baie, QC) engaged to manage the project. Both high-resolution magnetic and time-domain electromagnetic (‘TDEM’) data were collected, for a total of 135 line-kilometers. This cost effective geophysical configuration is particularly well-adapted for reconnaissance surveys, with the objective of delineating graphitic conductors to a depth of about 125 meters while maintaining good spatial resolution.

300 Metre Long Electromagnetic Anomaly on Miller Hydrothermal Lump/Vein Graphite Property

Posted by on Monday, 23 September, 2013

Canada Carbon Inc. announces that preliminary VTEM airborne survey results from Geotech Ltd. (Aurora, ON), have identified multiple anomalies over the 20.7 square kilometre Miller hydrothermal lump/vein graphite property. Of greatest significance is a large anomaly that extends from the previously announced (VN1) graphite vein discovery for 285 meters (m) to the southeast and 15 m to the northwest. This large anomaly, located within the eastern claim block, is elongated towards the east and also correlates with a magnetic gradient. This can be explained by the main source of the anomaly dipping east or by the presence of other smaller anomalies on the east flank. The VN1 discovery is located on the eastern flank of the anomaly and this area is now being surveyed by beep-mat combined with trenching. To date, 40 m of the anomaly’s 300 m length has been trenched by working on the vein discoveries. The main anomaly is still being explored; however geophysical modeling should give the location and depth of its source.

R. Bruce Duncan, CEO & Director of Canada Carbon, stated, “The fact that our largest and strongest electromagnetic anomaly leads right to our active trenching at the VN1 vein system is very exciting. It points to significant upside for further expansion of the VN1 vein system, as well as for additional discoveries as we look for the source of the 300 meter anomaly. In addition, other anomalies revealed through the survey show enough size to further justify exploration over each of them. The Company is very pleased with the high-precision and high-quality data collected to date which will allow us to focus on the most promising targets for additional graphite vein discoveries.”

Geotech is expected to produce the final data maps, along with the selection of high priority anomalies which will allow us to choose specific targets to model within the next 4 weeks. The Company’s technical team found three additional anomalies in the immediate vicinity of the VN1 anomaly, for a total of four anomalies, which are completely or partly on land where a surface access agreement has been obtained (see news release, September 5th) and so are the subject of exploration at this moment. Two are located 360 m and 680 m to the southeast of the trenching area and are 240 m and 80 m long, respectively. Many old exploration pits with graphite blocks are in the area of these anomalies. The fourth anomaly is 730 m north east of the trenching area and will be explored by drilling since no outcrop is present on site. That anomaly is 150 m long.

The Company’s west claim block shows seven anomalies but the interpretation of Geotech will be important in confirming those anomalies as being from a bedrock source, since many other anomalies are related to cultural effects. Initial prospecting will be conducted on each target area to determine a priority for future work. The completion of the modeling by Geotech will also help in determining targets to explore while trenching continues.

Regional geology and claim potential

The Miller-Graphite Mine is classified as a skarn deposit. The contact between a pegmatite intrusion anda marble unit has been mineralized by fluids coming out of the intrusive body. The claims are inside the same major geologic unit where marbles and pegmatite are present.

Another past worked zone is east of the deposit and its location is unknown (Maurice, 1984) but would probably be inside the property. A prospecting phase in 1989 also found a mineralized zone 100 meters east of the deposit, on the property, (Blair, 1988) but it is unknown if this is the same zone as noted in Maurice (1984). The same prospecting phase also found ancient pits in the area but they were unexplored by the team. (GM47971) The presence of multiple graphite zone suggests a very interesting context for more graphite discoveries.

An inferred electromagnetic zone was discovered in 1988 and is on the property, south-west of the Miller-Graphite deposit. (Blair, 1987) Another electromagnetic anomaly is also present 70 meters east of the deposit and the anomalous spot was also stuck by lighting while a survey was being done which indicate a conductor body around the area. (Blair, 1988)


Continuing of geophysical investigations at Patterson Lake for uranium

Posted by on Tuesday, 17 September, 2013

Forum Uranium Corp. announces further exploration of its 100% owned Clearwater Project on trend and immediately adjacent to the southwest of the Alpha Minerals/Fission Uranium Patterson Lake South discovery. Forum conducted ground radiometric prospecting, lake sediment geochemical surveys and soil gas radon surveys in late August/early September.

As a result of this program, further prospecting of airborne radiometric anomalies and expansion of the radon survey will take place. The radon survey has outlined a number of anomalous zones on two grids immediately southwest of the Alpha/Fission claim boundary. These results are very encouraging so the grids will be expanded to cover areas with airborne electromagnetic conductors on strike with the Patterson Lake South conductive trend. Upon completion of this follow-up program, Forum will conduct ground electromagnetic surveys this fall and ground gravity in early winter to outline targets for drilling in late January 2014.


Results from Spring Exploration on Ring of Fire

Posted by on Friday, 9 August, 2013

MacDonald Mines Exploration has received the results from its Spring 2013 drill program targeting volcanogenic massive sulfides (“VMS”) in the Ring of Fire (“ROF”).

The history of geophysical investigation of the property can be found here.

Two drill targets were tested during the program over the Butler 3 and Butler 4 targets respectively. The Butler 3 drilling did not hit appreciable copper or zinc mineralization, but did intersect hydrothermally altered felsic and intermediate volcanic rocks that are indicative that the drill holes are proximal to a large VMS body. The Butler 4 drilling intersected copper and zinc mineralization that Company geoscientists believe to be associated with stratabound mineralization that extends to depth.

“MacDonald is keenly aware that the market, especially today, is only motivated by huge success. James Bay exploration is tough, it is a wetland with little outcrop. Consequently we must utilize drill results for ongoing quantification that further exploration is warranted. The Butler 3 and Butler 4 targets have all the necessary components for discovery:

  • A large heat source (ultramafics, proven komatiates)
  • Laterally extensive alteration (a large system)
  • Known mineralization; zinc, copper, silver and lead
  • Secondary mineralization typically associated with larger VMS systems – tin, enrichment of P2O5 “icelandite”
  • Geophysical signatures (EM, IP, magnetics, and gravity)

We believe we are now moving to the final stages of our exploration efforts. We have quantified geochemical, geophysical and geological (structural) targets and are working on prioritizing these for the next stage of exploration. We expect to be drilling in the fall of 2013 after a full compilation of the data.” – Kirk McKinnon, President & CEO

Two drill holes (BP13-CU19 and CU20), were drilled on the Butler 3 geochemical/geophysical anomaly. No appreciable copper or zinc mineralization was intersected within these drill holes, however the lithologies intersected sodium depleted intermediate and felsic volcanic rocks. This geochemical signature represents a classic alteration vector for VMS mineralization, and leads Company geoscientists to the conclusion that VMS mineralization is to the south-west.

The targeting of the south-west likely represents the extension of the mineralized zone intersecting in drill hole BP12-Cu14. It appears that BP12-Cu19 and BP12-Cu20 are lateral to the mineralized zone.

  • Hole BP12-Cu14 intersected 41.5m of 0.4% Cu, 3.26% Zn and 6g/t Ag
    • Including:
    • 12.5m of 8.54% Zn and 6.24 g/t Ag
    • 5.0m of 1.18% Cu, 3.86% Zn and 14.48 g/t Ag

The target area to the south-west is corroborated by a coincident EM and IP anomaly. Before drilling this target however, the Company intends to conduct a robust structural analysis of the existing drill holes under the direction of Rogerio Noal Monteiro, Ph. D. (Vektore Exploration and Consulting). This data will be used in conjunction with the geochemical and geophysical vector analysis to guide drill targeting.

Drill holes BP13-CU21 and CU22 were drilled on the Butler 4 geophysical anomaly (with coincident IP and EM geophysical anomalies). BP13-CU22 intersected 7.50% zinc over a 3 metre interval, and 0.23% copper over 2 metres. Drill hole BP13-CU21 intersected 0.15% copper over a 12 metre interval. These drill intersections are significant in that they pierced the upper edge of a large sub-vertical electromagnetic plate that was postulated to be associated with VMS mineralization. Now that the Company has verified that this geophysical target is associated with copper and zinc mineralization, a detailed analysis of the structural geology will be undertaken on the target. This information, in conjunction with geochemical and geophysical analysis will be used to develop discrete drill targets.


Airborne EM and radiometric surveys for Saskatchewan uranium exploration

Posted by on Thursday, 8 August, 2013

Noka Resources Inc. announces that the members of the Western Athabasca Syndicate; Noka Resources Inc.Skyharbour Resources Ltd., Athabasca Nuclear Corp., & Lucky Strike Resources Ltd.(“the Syndicate”) have completed large-scale VTEM plus and radiometric geophysical surveys on the Western Athabasca Syndicate Project located near Alpha Minerals’ and Fission Uranium’s  Patterson Lake South (“PLS”) uranium discovery. The original airborne coverage was expanded to provide for the infill and extension of conductive anomalies and structural features identified by a preliminary review of the geophysical data. Based on this initial encouraging data, the Syndicate has elected to immediately commence the second phase of its summer program consisting of follow-up field work and ground-truthing of geophysical targets.

Western Athabasca Syndicate Project Claims Map: http://www.nokaresources.com/images/NX-Western-Basin-Syndicate.jpg

Completion of Regional Airborne Geophysical Survey:

A total of 4,840 line kilometres was flown for the VTEM plus time domain survey with an additional 4,400 line kilometres flown for the radiometric survey all of which was on the Syndicate’s Preston Lake Property. The VTEM plus system has been used successfully to locate basement conductors similar to the structures that host the high-grade uranium discoveries at the nearby PLS project. The high resolution radiometric survey was flown to locate uranium boulder trains, in-situ uranium mineralization and alteration associated with uranium mineralization which is what ultimately led to the PLS discovery by Alpha and Fission. Phil Robertshaw (P.Geo., Saskatchewan) is reviewing the collected data and will be providing detailed interpretation of the VTEM plus and radiometric surveys shortly.

Western Athabasca Syndicate Airborne Survey Coverage: http://nokaresources.com/images/NX-Geophysics-coverage.jpg

The areas flown include two blocks in the northern part of the Preston Lake Property. The Preston Lake South block is contiguous with Fission Uranium and NexGen Energy and includes a large area of partially exposed pre-Cambrian shield rocks. The Preston Lake West block claims are contiguous with claims controlled by Aldrin Resources and Forum Uranium. The claims are underlain by Phanerozoic rocks (limestone and sandstone) similar to the PLS discovery area. At Fission and Alpha’s PLS high-grade discovery it is interpreted that the uranium has been mobilized along the fault zones and has been concentrated in the sandstone under the limestone. A review of historic data on the Preston Lake Property has identified a sample collected by the Geological Survey of Canada which returned a value of 5.4 ppm U3O8, considered to be significant in an area with a background uranium value of 1 ppm U3O8. This high U3O8 value may indicate either the down-ice glacial transport of uranium boulders from source or an in-situ source of uranium. For comparison, the highest value down-ice from the PLS discovery is 3.2 ppm U3O8. Management cautions that past results or discoveries on proximate land are not necessarily indicative of the results that may be achieved on the Western Athabasca Syndicate Project.

Commencement of Field Program at Preston Lake Property:

The initial data and results from the airborne surveys have led the Syndicate to expedite the planned summer field program with a number of high-priority targets at the Preston Lake Property being the focus of the work. A sophisticated targeting matrix is being used to further identify and prioritize areas for ground-based follow-up. Field work will include ground-truthing of high-priority geophysical targets using water and soil radon sampling, biogeochemistry, geochemical lake sediment and soil sampling, prospecting, and scintillometer surveying. The Syndicate will employ a systematic, proven and cost-efficient exploration methodology that has led to numerous uranium discoveries in the region and throughout the Athabasca Basin. By the end of this summer’s field program, a total of $1.5 million will be spent in exploration on the project between airborne geophysical surveys and follow-up ground work.

Uranium and the Athabasca Basin:

The Athabasca Basin of northern Saskatchewan hosts the world’s largest and richest high-grade uranium deposits accounting for just under 20% of global primary uranium supply. Athabasca uranium deposits have grades substantially higher than the world average grade of about 0.1% U3O8. The Patterson Lake area has received escalating exploration attention and claim acquisition activity as a result of the new, shallow discoveries made by Alpha and Fission which includes the recently reported drill interval of 6.26% U3O8 over 49.5 metres in drill hole PLS 13-053. This mineralized zone is located approximately 400 metres to the northeast of discovery hole PLS 12-024 which returned 2.49% U3O8 over 12.5 metres. Consistent high grade, near surface U3O8 assays from Alpha and Fission demonstrate the potential for high grade uranium mineralization on the margins of the western side of the Athabasca Basin. There are still areas in the Athabasca region that are highly prospective and underexplored for high grade uranium as illustrated by Alpha’s and Fission’s recent discovery.
