Airborne EM and down-hole gravity for gold intersection in NW Ontario

Posted by AP on Thursday, 16 May, 2013

Northern Shield Resources Inc. announces the intersection of significant visible gold during the first phase of a 3,000 metre drilling program being carried out this spring at the Wabassi VMS (volcanogenic massive sulphide) project located in northwestern Ontario. The Wabassi project is being explored under a 49/51 JV with Discovery Harbor Resource Corp.

In the process of drill testing Anomaly “N” (a high priority VTEM conductor defining a massive sulfide target), a quartz-carbonate alteration zone with a veinlet of visible gold was intersected from 98.8 to 98.95 metres in drill-hole 13WA-33. The 0.15 metre sample assayed 2,530 g/t Au (73.8 ounces/ton). A second interval assayed 5.86 g/t Au over 1.1 metre from 100 to 101.1 meters. The auriferous zone appears to be related to an intermediate intrusive dike or sill and occurs at the contact of this intrusive and the altered mafic volcanic rocks. Photos of the core containing the gold veinlet can be seen on Northern Shield’s website at www.northern-shield.com.

This intersection of gold is the fourth gold discovery that has been made to date within the Wabassi-Tempest properties and the second to contain visible gold. Globally, gold mineralization is present in a majority of VMS districts.

In total, four drill holes were completed in the first phase of the program, which was aiming at testing three VTEM targets (K, M and N). No other significant mineralization was identified nor was anything intersected to explain the VTEM anomalies.

A down-hole gravity survey (Gravilog) was also recently completed by Abitibi Geophysics at Anomaly E. The results from the survey show dense masses in the subsurface that are coincident with and ‘off hole’ from drill intercepts where strong zinc-copper-silver mineralization is present. The upcoming drill program will include the testing of these newly defined targets at Anomaly E, including tests to determine whether the modeled shallow mineralization is present as well as the mineralization modeled at depth. Sketches representing 3D models of the gravity survey results are posted on Northern Shield’s website.

The second phase of drilling is planned to resume immediately after the spring breakup period, likely at the end of May, 2013. Much of the second phase will be focused on continuing to define the copper-zinc-silver-gold mineralization at “E.” This includes several gravity anomalies, which support previous geophysical interpretation that the mineralization extends at depth. Additional drilling will also be planned to test this exciting new gold discovery at “N”.

The Wabassi project is being overseen by Christine Vaillancourt, Chief Geologist for Northern Shield and a Qualified Person under National Instrument 43-101. The drilling was conducted by Vital Drilling Ltd. of Sudbury, Ontario. Samples were analyzed by ALS Minerals laboratories in Vancouver, BC for Au by fire assay with ICP-AES finish and base metals by four acid digestion and ICP-AES. Ore grade gold was analyzed with ALS’s Au-GRA21 method, a fire assay with gravimetric finish. Down-hole gravity was completed by Abitibi Geophysics Ltd. of Val d’Or, Quebec.

Northern Shield is an innovative, results-driven Canadian company focused on Platinum Group Element (PGE) and nickel-copper-(PGE) exploration in Canada and Greenland and copper-zinc-silver exploration on its Wabassi and Storm properties in northern Ontario. Its mission is to create a successful mineral exploration company through technical excellence and efficient management, where success is measured by the identification and development of high-quality mineral exploration projects, which may ultimately be optioned, sold or developed for maximum return on investment.


Graphite discoveries in Northeastern Ontario

Posted by AP on Thursday, 16 May, 2013

Zenyatta Ventures Ltd. announced a drilling update on the 100% owned Albany (Hydrothermal) Graphite Deposit, located in northeastern Ontario, Canada.

The first drill hole (Z13-4F10) intersected 363 metres (‘m’) of graphite mineralization from 47.0 m to 410.0 m.  This represents the widest zone of graphite material intersected to date on the Albany deposit.  The hole, which was drilled at a 180 azimuth and -65 dip, was designed to test between previously drilled holes 5 and 9.  From surface to 41.0 m hole 10 intersected overburden and from 41.0m to 47.0 m intersected Paleozoic limestone.  Graphitic overprinting was encountered from 47.0 m to 87.0 m, while the strongest graphitic mineralization was intersected from 87.0 m to 410.0 m. Drilling shows different types of graphite mineralization consisting of clasts of graphite vein material, disseminated graphite matrix and discrete graphite veins / veinlets as part of a large breccia pipe.  Geometry and true width of the graphite breccia pipe is difficult to determine at this point and will require much more drilling.

The Company will continue to define the size and grade of this rare, ‘vein-type’ or hydrothermal-style graphite deposit.  The goal of the current program will be to expand on a 2012 drilling campaign that intersected a large mineralized zone of graphitic breccia and veining from widely spaced drill holes.  This previous nine (9) hole drill program succeeded in establishing widespread graphite mineralization laterally for several hundred metres and to a vertical depth of 400m, where it remains open. The current drilling will consist of a minimum of 10,000m and will further test the extent of the Geotech VTEM airborne conductor. The program will require 40 holes and is expected to continue until August, after which a NI 43-101 resource estimate will be calculated. The Company anticipates a steady flow of information from drilling activities and continued metallurgical work from this fully funded $4 million exploration program for the balance of 2013.

14 May 2013

Zenyatta Ventures Ltd. announced the following significant assay results from the first hole (#10) of the current campaign on the 100% owned Albany (Hydrothermal) Graphite Deposit, located in northeastern Ontario, Canada.   Drill hole 10 intersected 360.8 metres (‘m’) of graphite mineralization from 49.0 m to 409.8 m yielding an average grade of 5.1% Carbon (‘C’).  This represents the widest zone of graphite material intersected to date on the Albany deposit.  The hole, which was drilled at a 180° azimuth and -65° dip, was designed to test between previously drilled holes 4, 5 and 9.  Five more holes have since been completed, all of which yielded broad intervals of graphite mineralization from visual observations of drill core as described below.  Holes 11 through 15 have been designed to start outside the limit of the indicated anomaly and were angled to help define and confirm the overall geometry of the pipe-like body.  Drill hole data from all 15 holes is shown in a table at the end of this press release.

• Drill hole 11 intersected 202.0 m of graphite mineralization from 393.0 m to 595.0 m.

• Drill hole 12 intersected 195.0 m of graphite mineralization from   90.0 m to 285.0 m.

• Drill hole 13 intersected 219.0 m of graphite mineralization from   96.0 m to 315.0 m.

• Drill hole 14 intersected 286.9 m of graphite mineralization from 108.8 m to 395.7 m and a second zone of 127.3 m of graphite mineralization from 431.3 m to 558.0 m

• Drill hole 15 intersected 301.9 m of graphite mineralization from   63.3 m to 365.2 m.   (All lengths reported are drill intersected core lengths and do not represent true widths)

Aubrey Eveleigh, President and CEO stated “These latest results confirm the exceptional size potential of the Albany graphite deposit and along with the previously announced ultra-high purity (>99.99% C) values, underpins Zenyatta’s extraordinary graphite project. Hole 10 represents the best grade drill intersection obtained to date and the more recent drill holes are confirming both the internal continuity and the extent of the deposit.”   Graphite mineralization appears to consist of graphitic breccia pipes which are typically surrounded by a zone of graphite overprinted syenite. Carbon analyses for drill holes 11 through 15 will be released once received.  Drill hole 16 has commenced, and the current campaign will continue until sufficient drill holes have been completed, following which a NI 43-101 compliant resource estimate will be prepared.  A plan map, section and drill hole table will be placed on the website today.

The Company has also completed a ground geophysical survey to better define the geometry of the Albany graphite breccia pipes and expects the full data to be released in the next few days once a final report has been completed by Crone Geophysics and Exploration Ltd. The survey has defined two adjacent, strongly conductive, geophysical (EM) anomalies that are roughly circular in shape.  Holes 10 through 15 were drilled on the eastern most anomaly (Eastern breccia pipe), and are suggesting an oval shaped body approximately 200 metres in a NW-SE long axis by approximately 125 metres NE-SW.  Additionally, hole 11 intersected mineralization at approximately 500 metres vertical depth.  Drill intercepts appear to be correlating well with the shape of the ground geophysical anomaly with additional drilling required to confirm this model. The western anomaly (Western breccia pipe), which appears to be larger, will also be fully tested during the current drill campaign.


Drilling in the Snow Lake greenstone belt

Posted by AP on Thursday, 2 May, 2013

MS Ventures Inc. updates shareholders on the progress of its winter drill programs.

The Company has completed drill testing its 100%-owned base metal massive sulphide-type targets in the Snow Lake greenstone belt of Manitoba and several targets in the North Range of the Sudbury Basin, Ontario. All targets in Manitoba have been selected for drill testing subsequent to the integration of airborne VTEM or ground EM-magnetic geophysical surveys and Mobile Metal Ions (“MMI”) soil geochemistry coupled with a review of historic exploration databases. The Company completed 13 holes with two holes abandoned due to low water supply for a total of 3,259.9 metres. In Sudbury, the Company completed three skid mounted drill holes following up TDEM, VLF-EM and MMI anomalies on the Terra Incognita project for a total of 440.6 metres.

Drill testing of Manitoba targets began on the Reed East project and finished on our Copper project. All targets were confirmed as uneconomic iron sulphide mineralization, generally associated with graphitic argillite within basaltic host rocks.

Neil Richardson, COO states: “The cold winter and spring have been exceptionally good for skid mounted drilling with frozen ground providing good access to many of our planned targets. The cold weather created some problems with small ponds frozen solid, providing an inadequate water source for drilling of two targets. We continue to see excellent correspondence between our geophysical targets and the drill results in explaining the anomalies.”

The drilling for this season was completed on April 17, 2013. The final assay results for the last few holes are outstanding at the time of writing.

Airborne and ground geophysics on Swayze Gold Property

Posted by AP on Thursday, 14 March, 2013

GoldON Resources begins 2013 Exploration on Swayze Gold Property in Ontario’s Abitibi Greenstone Belt – Video Summary on www.investmentpitch.com

Based on interpretation of airborne geophysical data, GoldON Resources’ independent geological consultant has identified a priority area for the next phase of exploration on the company’s 100% owned Swayze Gold Property.

The 6,640 hectare Swayze Project, comprised of three non-contiguous claim blocks, is located half way between Timmins and Sudbury, Ontario in the Swayze greenstone belt, which is the southwestern extension of the Abitibi greenstone belt. These properties either adjoin or are surrounded by Iamgold’s multi-million ounce Cote Gold Project. Iamgold is GoldON’s largest shareholder, holding two million or approximately 10% of the outstanding shares.

The geological interpretation focused on the 6,000 hectare Neville Potier claim block, and while there were several areas that show good promise in terms of geology and structure, one area reportedly stood out above the rest as shown on the Aeromag map. Of particular significance is a major magnetic low that includes the historical Chester gold operations and the Côté Gold deposit and extends north into GoldON’s Neville Potier claims. This geophysical feature could be indicative of a major alteration system

Previous drilling on the Chester property encountered anomalous gold and similar alteration and fracturing as found at the Côté Gold deposit less than 1 kilometre to the south.

Access to the priority area of the Neville Potier claims is excellent year round with a paved road through the middle of the claims.

The company is arranging an equity financing to further fund the next phase of exploration on this property and Iamgold has expressed an interest in participating.

Line cutting and an IP /resistivity geophysical survey will commence shortly. The results of this survey will be used to identify the highest priority drill targets.


New Airborne and Ground Geophysical Surveys on Detour Gold Trend Properties

Posted by AP on Friday, 1 March, 2013

Adventure Gold Inc. announces the commencement of a significant exploration program on its 100%-owned Detour Quebec project along the Detour Gold Trend (“DGT”) in Abitibi, Quebec. The exploration program will consist of airborne and ground geophysical surveys on the best targets identified last year following a comprehensive geological modeling of the DGT. A helicopter-borne electromagnetic VTEM-type survey (VTEM) totalling 575 km, 400 km of detailed ground magnetic surveys and 30 km of Induced Polarization (IP) surveys are currently underway or will start soon.

Since last year, the Company has been actively exploring its Detour Quebec properties by completing 103 kilometres of IP surveys, 365 kilometres of detailed ground magnetic surveys, and 912 kilometres of high-definition helicopter-borne magnetic surveys. This work has highlighted new and very promising drilling targets by identifying IP anomalies close to strong gold anomalies in till, along strike from positive gold results intersected by historical drill holes. Geological modeling outlined nine possible distinct bedrock source areas along the Sunday Lake, Massicotte, and Lower Detour/Grasset gold deformation zones on our properties. Three possible bedrock source areas were covered by geophysical surveys (IP and Mag) in 2012 and nine new ground geophysical surveys will be completed over the other areas this year (see Figure 1 and press release dated November 14, 2012).

On the two northernmost claim blocks (Manthet and Martigny) respectively located 15 and 25 kilometres from the Detour Lake mine, adjacent and close to the Ontario border, two VTEM surveys totalling 575 km will be completed. Historically, very little exploration work has been completed on these claims and limited drilling in one area outlined VMS-style gold, zinc and copper mineralization. This geological environment shows some similarities with the Martiniere project located further east, where Balmoral Resources Ltd is actively exploring the Martiniere West, Bug Lake, and Martiniere East zones. In this emerging gold play, very high-grade drill intersections were recently reported, namely 273.0 g/t Au over 3.9 metres and 11.7 g/t Au over 8.9 metres (see Balmoral Resources Ltd press releases dated August 16, 2012 and January 28, 2013). The VTEM-type survey is known for its exceptional depth penetration and provides a more accurate definition of electromagnetic anomalies than conventional systems. At the Detour Lake mine, the original discovery of the main zone is directly credited to the presence of an airborne electromagnetic anomaly detected during an Input-type survey in 1974. On the Manthet and Martigny claim blocks, new east-west and northwest trends outlined last year and interpreted as subsidiary faults of the Sunday Lake deformation zone will be covered by the VTEM survey.

“Following recent successes in identifying quality drilling targets, firstly by outlining the best areas using our comprehensive geological model and secondly by performing detailed geophysical surveys, we have great expectations for the 2013 geophysical surveys, which will be mainly conducted over new claims acquired in April 2012. Once this work has been completed, we will plan a substantial drilling program scheduled to start next winter”, stated Marco Gagnon, President and CEO of Adventure Gold Inc.

The Detour Quebec project includes nine properties, 100%-owned by the Company, totalling 747 claims and covering a surface area of 40,397 hectares or 404 km2. The Detour Quebec properties are strategically located along the DGT over 80 km strike length and encompass three major proven gold structures, namely the Sunday Lake, Massicotte, and Lower Detour/Grasset deformation zones. The DGT hosts the Detour Lake gold deposit with NI 43-101 proven and probable reserves of 15.6 M ounces of gold (from global measured and indicated resources of 23.3 M ounces and inferred resources of 5.8 M ounces: see Detour Gold Corporation press release dated January 25, 2012). Adventure Gold’s Detour Quebec properties are adjacent to Detour Gold Corporation properties located on the Ontario border.

Jules Riopel, P.Geo., Vice-President Exploration and Acquisitions, acting as the Company’s “Qualified Person” as defined by NI 43-101, has reviewed this press release and supervised the exploration program on the Detour Quebec properties.


Down Hole Geophysics Confirms Significant Conductor at New Morning in Western Australia

Posted by AP on Saturday, 2 February, 2013

Western Areas Ltd provides an update from ongoing exploration activities at the new high grade discovery at New Morning, within the company’s

flagship Forrestania Nickel Operation.

Highlights

  • Assays have confirmed and extended the high grade discovery increasing the initial Niton estimate of 2.7m at 5.5% nickel to 3.0m at 6.3% nickel, including 2.4m at 7.6% nickel;
  • A down hole electro-magnetics survey (DHEM) has confirmed the company’s initial expectation that the high grade discovery hole has only intersected the edge of the mineralised zone with initial modelling indicating a plate approximately 150m x 250m wide; and
  • Forward work program being rapidly defined – initial steps to expand the discovery will see an immediate second drill hole commenced from the parent hole, targeted towards the centre of the modelled DHEM plate, followed by further DHEM tests to further refine targeting.

Western Areas Managing Director, Dan Lougher, said the Company was eager to follow up the recent geophysics and high grade assays with a sustained drilling program.

“We have previously stated that we believe the 6km between our two high grade mines of Spotted Quoll and Flying Fox are the most prospective for identifying a new high grade nickel deposit. Whilst drilling is still at an early stage, it is pleasing for the entire team to see the strategy starting to deliver results,” said Mr Lougher.

“The Forrestania Nickel Operation is a fully developed brownfields site, with power, water, roads and associated infrastructure all located along the prospective 6km belt meaning that any new deposit can be turned into an operating mine quicker and cheaper than any new greenfield discovery.

“We look forward to providing the market with updates as we continue drilling at New Morning,” said Mr Lougher.

Assays

Assays have now been received and have confirmed the high grade nature of the intercept, with improved intersection length and grade from the Niton measurements previously announced. NMD177 now measures 3.0m at 6.3% nickel, including 2.4m at 7.6% nickel. Deleterious elements (principally arsenic) are very low, and similar to the levels seen at Flying Fox.

Down Hole Electro-Magnetics

A DHEM test has been conducted on the lower portion of NMD177 with Newexco implementing the geophysical survey. The initial interpretation of the data by Western Areas’ exploration staff and Newexco indicates that a significant off-hole conductor exists to the south and slightly higher than the intersection announced. Whilst it is difficult to define the extent of the conductor from one hole, modelling of the DHEM data indicates a plate of approximately 150m by 250m. The DHEM data also indicates the current drill hole has not intersected the central portion of the plate, confirming our expectation that we may have only intersected the edge of this discovery.

The New Morning deposit is a medium grade nickel deposit, lying between the high grade Flying Fox and Spotted Quoll deposits.

The company believes that the potential for further Flying Fox or Spotted Quoll style mineralisation in this area is high, and significant exploration resources have been devoted to testing this area.


Seismic, gravity and magnetotelluric dataset from Geoscience Australia

Posted by AP on Thursday, 31 January, 2013

The final seismic, gravity and magnetotelluric dataset from Geoscience Australia’s Onshore Energy Security Program has been processed and released.

The data were acquired in 2011 by Geoscience Australia in conjunction with the Geological Survey of Western Australia (GSWA) as part of the Western Australian Government’sRoyalties for Regions Exploration Incentive Scheme. The 484 kilometres of data were obtained over the Yilgarn Craton, Officer Basin and Musgrave Province of Western Australia. This survey will provide precompetitive data for energy and mineral exploration, and for potential water resources. These data, combined with the 2001 Northern Yilgarn Survey, and the 2010 Capricorn and Youanmi Surveys result in a complete cross section of central Western Australia.

Overall, more than 6500 kilometres of deep crustal seismic data were acquired during the Onshore Energy Security Program, providing valuable structural information for the Australian crust from the near surface to the Moho, boundary between the Earth’s crust and the mantle. As well as providing precompetitive data, the surveys have helped to expand understanding of the complex structures and geology of the Australia continent.

The processed SEGY data, images and ancillary information are now available for free download.

Interpretation of the seismic and magnetotelluric models undertaken by GSWA and Geoscience Australia geoscientists will be presented at a public workshop in Perth in June 2013.

Induced Polarization Survey on Abitibi Greenstone Belt, Northwestern Quebec

Posted by AP on Thursday, 10 January, 2013

Belmont Resources Inc. updates the progress on the Berthiaume (the “Be”) property.

Geosig Inc. of Quebec completed approx. 46.2 km. of induced polarization (TDIP) geophysical survey with a dipole-dipole electrode configuration on the three areas line cut, and as recommended in the NI 43-101 Report to establish the potential of the structural features of the property. A provision for drilling has been budgeted to test the IP anomalies from the IP survey interpretation, which is expected in a couple of weeks.

The Be Property is located halfway between the towns of Matagami and Lebel-sur-Quevillon, located in the prolific Abitibi greenstone belt of northwestern Quebec. It consists of two designated claim blocks of eight claims covering 447.84 ha (West Block) and 23 claims covering 1,287.56 ha (East Block).

Regional and local geology

The Berthiaume property is located in the Harricana-Turgeon Belt, an Archean volcano-sedimentary and plutonic rocks assemblage that constitutes the northern part of the Abitibi sub-province, Superior Province (Hocq, M. DV 89-04). Volcanic and sedimentary rocks of the Berthiaume area (Joly, M., MB 93-13) occur as a homoclinal sequence striking east-west, dipping steeply to the north with a polarity also to the north. From bottom to the top (from south to north), the belt starts by massive to pillowed mafic volcanites known as the southern volcanites. These are surmounted by a thick sequence of clastic sediments and iron formations that belong to the Taïbi Group. Farther north lies a thick bimodal sequence of felsic lavas and pillowed, vesicular and porphyric mafic lavas. These are referred as the northern volcanites. The north and south borders of the Harricana-Turgeon Belt are composed of large felsic, mafic and ultramafic intrusive bodies. One of these is the Bell River anorthositic complex, which covers the northern part of Berthiaume Township. The metamorphic equivalents of the lavas and sediments are observed along the borders of the
intrusions as amphibolites (metavolcanites) and biotite-quartz schists (metasediments). NNE striking diabase dykes of kilometric extension constitute the younger geological unit as they cut all the other formations.
A penetrative E-W and sub-vertical schistosity is observed everywhere. The most extensive structures are E-W shear zones, followed by NE to NS striking faults.
The only mineralization reported on this property consists of massive pyrite and pyrrhotite horizons containing sphalerite and chalcopyrite locally in quantities ranging from trace to a few percent. In Umex drill holes, in the northeast part of the East Block, such mineralization was hosted by various graphitic rocks including argillites, breccias and conglomerates. As mentioned previously, highly-oxidized outcrops containing up to 70% pyrite and pyrrhotite with low values in Cu and Zn were also found in the same area during geological mapping by Falconbridge.

Joutel Property – Exploration Planning

The Company will also be considering recommended line cutting and IP work next on its Joutel Township optioned property. Significant activity has been announced recently by other exploration companies in the Joutel area such as: Bold Ventures Inc. (“BOL”)-December 7/12 nr; Visible Gold Mines (“VGD”)-December 4/12 phase 2 drilling nr; and Globex Mining (“GMX”)-November 5/12 nr announcing recent acquisition of 100% interest in the former Joutel copper mine (copper, zinc, silver) where Globex already has landholdings that include the 100% owned Eagle gold (gold, silver) and Poirier mines (copper, zinc, silver, gold), and a large package of prospective claims with excellent exploration potential.


Results from Induced Polarization (IP) Survey in the Dominican Republic

Posted by AP on Thursday, 20 December, 2012

GoldQuest presents the initial data from an extensive IP survey and a summary of the 2012 drilling at Las Tres Palmas project, in the Dominican Republic, which includes the Romero and Escandalosa discoveries. The company has ordered a fourth drill rig, capable of reaching 700 metres, which will be mobilized in January 2013 to drill new targets. Assays from the remaining 9 holes drilled at Romero in late 2012 will be released in January 2013.

The Company is currently undertaking an IP survey covering the complete Las Tres Palmas trend and outlying areas in the Company’s extensive land position, including Los Comios, Romero West, and Jengibre. This survey, conducted by Insight Geophysics, will investigate to a depth of approximately 500 metres, which is almost twice the depth of the 2011 IP survey that identified the Romero mineralization. Initial results of the current survey at Romero and north of La Escandalosa have identified deeper chargeability anomalies, where higher readings appear to correlate with sulphide mineralization (http://goldquestcorp.com/images/romero_map_new_insight_ip_lines.jpg).

“The 2011 IP program which led to the Romero discovery identified the overall trend, and the new, deeper penetrating IP shows strong correlation with the high grade copper/gold intersections and provides further guidance about the geometry of the targets,” commented Julio Espaillat, GoldQuest’s President and CEO. “Drilling in the new year will continue at Romero, which remains open at depth and along strike, and will test new targets around the Las Tres Palmas Trend.”

The IP survey at Romero, which is located in the most northerly lobe to date of the Las Tres Palmas trend, displays enhanced detail of resistivity and chargeability anomalies, allowing the Company to refine their planned drilling targets, and to gain a greater understanding of the mineralization style and attitude of controls on emplacement of gold, copper and other metals (seehttp://goldquestcorp.com/images/romero_200w.jpg). The East-West mineralized trend in the northern part of the Romero chargeability anomaly, identified in 2012 by drilling, is visible in this survey, and appears to shows a strong vertical element, strengthening at depth. The Company intends to undertake further drilling in January to test the high chargeability occurrences with three diamond drill rigs, closely followed by testing further refined IP targets as they are generated.

Several IP survey lines have been completed directly north of La Escandalosa outcropping gold occurrence, 2 kilometres south of the Romero discovery, where the company reported a NI 43-101 compliant inferred resource of 3.1 million tonnes grading 3.14 g/t gold (see release of Aug 20th, 2012). The first IP survey lines show a strong chargeability anomaly and La Escandalosa mineralized horizon dips towards this untested anomaly which is open at depth and to the north (see http://goldquestcorp.com/images/escandalosa_IS100N-IP-UTM.jpg). Drilling will commence here with a deep rig, slated to arrive in the Dominican Republic in late January.

The San Juan project was discovered by GoldQuest geologists during the Gold Fields-funded regional exploration programme in an area believed to have no previous history of mining or exploration. The project occurs in the Cretaceous Tireo Formation which comprises of a mixed volcanic package dominated by lavas and volcanoclastics.


Electrical Resistivity Tomography for placer gold deposit in Quebec

Posted by AP on Wednesday, 19 December, 2012

Uragold Bay Resources Inc. announces that the INRS (Institut National de la Recherche Scientifique) will be conducting a Syscal-Pro electrical resistivity tomographic survey and a Promis-10 electromagnetic FDEM survey on the Rang Chaussegros claims of UBR Beauce Gold property located in the municipality of Saint-Simon-les-Mines in the Beauce region of southern Quebec.

The INRS team, led by Dr. Marc Richer-LaFlèche, Ph.D (Geo) will perform a geophysical program that will include geoelectrical tomographic and frequency domain electromagnetic surveys. The geoelectrical tomographic survey will generate high resolution cross section images of the Quaternary overburden and the volcano-sedimentary layering of the bedrock formations of the Beauce Property. The result of the geoelectrical tomography will be correlated with Uragold’s sonic and other historical drilling data, in order to provide a 3D model of the placer gold channel composed of saprolite and brown basal till.

The aim of the program is to enable Uragold to evaluate, in greater detail, the shape, size, potential of the placer gold channel and to measure potential target extensions of the deposit. The program started last week with the cutting and picketing of a total of 7,500 meters of lines in order to form a rectangular grid on the property, between the Rang Chaussegros road to the west and Saint-Gustave road to the east. The grid will be used to perform the geoelectrical tomographic surveying.

Patrick Levasseur, president and COO of Uragold stated. “We are very proud that the special nature of our Beauce Gold project has attracted the scientific interest of the Quebec University INRS research team. This partnership will not only increase the overall understanding of the unique geological phenomenon of the region, but it will also allow us to establish an optimum mining plan for our Beauce Gold property.”

The Beauce Placer property was the site of Canada’s first gold rush in the 1850′s, years before the Klondike gold rush. Two of Canadada’s largest gold nuggets, the Kilgour nugget at 52 ounces and the McDonald nugget at 45 ounces, came from the Gilbert River, which flows through the property.

In the early 1960′s, the property was the site of a major placer gold mining operation. The Beauce Placer Company was the only commercial placer gold mining operation in eastern North America. The placers where mined with a floating Yuba dredge. The Company mined 56,000 oz of gold from an area representing less than 20% of the placer channel near St-Gustave road.

Gold production stopped in 1962 due to two major problems. First, they underestimated the depth of the overburden due to a westward dip of the bedrock. Therefore, the bucket-lined dredge of the Yuba dredge could no longer reach the auriferous pay zone. After modify the dredge by extending the bucket-lined boom, production-changed location to mine from west to east. Secondly, the Yuba dredge was designed to mine placer gold from sand and gravel. The pay zone in the western part of the channel consisted of clay (auriferous basil till). The dredge wasn’t equipment to separate gold from clay.

Induced Polarization Survey in Ghana

Posted by AP on Saturday, 8 December, 2012

Castle Peak Mining Ltd. announces Promising Surface Sampling Results at the Dansuom Target on the Pow Concession at the Company’s Akorade Project in the Southern Ashanti Belt in Ghana, West Africa. the Reported Results Represent Approximately 25% of the Road Samples Collected to Date. Concurrently a Gradient Induced Polarization Survey and Subsequent Pole-Dipole Induced Polarization Survey was Completed in Order to Better Refine Drill Targets in the Area.

Highlights of the Sampling Include:

  • Channel POWCS008: 70.0m of 1.01 g/t Au including 26.0m of 1.76 g/t Au;
  • Channel POWCS007: 12.0m of 0.54 g/t Au;
  • Channel POWCS005: 2.0m of 2.38 g/t Au.

Highlights of the geophysical survey include several kilometer scale coincident resistivity and chargeability anomalies. Two of these significant anomalies are spatially associated with the large, 1,500m by 250m, Dansuom gold in soil anomaly defined by soil values greater than 0.2 g/t gold. (To see Figure 1: Anomalies in Dansuom Target Area, please visit the following link: http://media3.marketwire.com/docs/cap1205i.pdf)


Commenting on the results Darren Lindsay stated, “Although dealing with a less than predictable rainy season this year, we have been able to forge ahead with geophysical surveying, mapping and sampling to better determine the resource potential in the Dansuom target area. Strong geophysical anomalies coincident with our existing geochemical anomalies and new road cuts exposing vein stock works, alteration zones and contact zones are showing the promise of this exceptional target.”

Update on Regional Exploration

A total of 690 samples for multi-element analysis have been collected across the Akorade project area, with approximately 300 samples remaining to be collected across the mineral licenses at 400m by 400m spacing. To date all samples from Enyinase, Bonsaso, Kedadwen and Dompem have been collected, while mapping and sampling still continues across the POW and Great Yorkshire licenses. Mapping from these efforts is being compiled to refine our existing base map.

Geology & Mineralization

The properties are underlain by NNE-SSW Birimian Age metavolcanics and Tarkwaian metasediments of the Ashanti Belt of southwestern Ghana. These rocks are intruded by two (2) chemically distinct granitic suites which consist of: 1) Belt associated Dixcove intrusive and 2) Basin associated Cape Coast intrusions.

Deformation and metamorphism of Birimian metavolcanics and Tarkwaian metasediments (conglomerates, arkose, sandstones, siltstones and shales) are related to the Eburnean II orogeny with five (5) distinct successive deformation phases, (D1 to D5) with D2 faults and D5 reactivation for major deformation events such as strike slip, dilatants breccias, quartz veins and lens networks with pinch and swells (boudinage) hosted within faults and shear zones.

Shear zones on the property are developed within the metavolcanics. The granitoid intrusions have been accompanied by hydrothermal activity evidenced by the numerous lenses of quartz veins and veinlets within the metavolcanics. The most prominent quartz structure, in a shear zone and within the metavolcanics on the Apankrah hills, has a NE-SW orientation and dips steeply to the southeast. The quartz vein, more than 1 metre in width and strike length of more than 100 metres is shattered and pyritized in few places.

The most favourable areas of gold mineralization in the Birimian and the Tarkwaian are found:

  1. In a major shear system in early Proterozoic rocks, e.g., Prestea and Obuasi
  2. In intermediate and mafic intrusions, mainly within the “greenstone” belts
  3. In mafic volcanics in some areas, especially in the Ashanti belt, e.g., Konongo
  4. In transitional zones between the belts and the basins
  5. The banket conglomerates of the Tarkwa district
  6. Oxide and laterite occurrences

The Bonsaso concession is dominated by well-foliated Birimian metasedimentary units. Detailed geological mapping of the concession is ongoing, but is hindered by the presence of a significant weathering profile. The geology is currently thought to be similar to that of the Iduapriem mine.

Gold mineralization in the area has been observed in shallow dipping quartz stockworks and veins. Quartz veins occur as a series of shallow dipping, thin, en-echelon quartz veins up to and greater than 10 centimetres wide. The veining is also associated with a quartz-pyrite alteration halo that extended several metres into the hanging wall and foot wall of the veins. This is thought to represent the type of deposit that typically forms along regional fault and fracture systems within Ghana, whereby fractures act as pathways for Au-bearing hydrothermal fluids. Precipitation of gold and quartz then results from changes in pressure, temperature and/or wall rock interaction. Mineralization is also associated with Tarkwaian conglomerates, probably of the Banket series and representative of placer mineralization, which is analogous to that at the Iduapriem mine. 


Induced Polarization geophysical survey at the Idaho Gold Project

Posted by AP on Saturday, 8 December, 2012

Premium Exploration Inc.  reports that a ground-based Induced Polarization (“IP”) geophysical survey at the Idaho Gold Project (“IGP”) has successfully outlined a new target at the X Zone. This new IP target exhibits coincident highly anomalous gold-in-soil and airborne mag/EM signatures. These characteristics are similar to those associated with the three known deposits along the IGP and suggest potential for the discovery of new gold mineralization at the Idaho Gold Project. Details.

This is the 12th advanced target identified on the project. These twelve targets all exhibit highly anomalous geochemical signatures associated with strong airborne magnetic and electromagnetic and ground IP geophysical anomalies. The majority of the targets are yet to be drill tested.

Drilling program after airborne geophysics for VMS

Posted by AP on Saturday, 8 December, 2012

VMS Ventures Inc.  announces plans for a 2013 winter drilling program on its 100% owned Manitoba properties.

Neil Richardson, VMS Ventures COO states: “We have many quality targets this winter, but we are particularly excited to get the drills turning on our newly acquired Reed East and Reed West properties. We consider them highly prospective as they cover a large area of the same volcanic rock package that hosts our high grade Reed Copper Deposit and Reed North base metal occurrences. VMS deposits tend to occur in clusters, within a specific package of these types of volcanic rocks.”

Diamond drilling is scheduled to begin in February and is expected to continue through April. Plans call for a budget of approximately $1.2 million which includes drilling 3,000 to 3,400 metres in 16 to 20 diamond drill holes. All target areas are within the Flin Flon – Snow Lake VMS greenstone belt of Manitoba.

Reed East and Reed West are adjacent to our Joint Venture property with Hudbay Minerals, which hosts the Reed Copper Deposit, currently being developed into a mine. These properties include targets with coincident Mobile Metal Ion (MMI) zinc anomalies and VTEM anomalies. Details.

–             The other winter 2013 targets on VMS Ventures’ 100% owned properties vary in their specific characteristics, but all are associated with geophysical EM conductors generally with associated magnetic anomalies and within interpreted volcanic host rocks. More detail will be provided on these targets in the New Year.

Applications for drill permits have been submitted to the Manitoba government. After drilling is concluded, holes with favourable mineralization, alteration or geology, will be surveyed with down the hole TEM using Koop Geotechnical. Koop will utilize borehole pulse electromagnetic equipment manufactured by Crone Geophysics.


CSAMT for gold in Paraguay

Posted by AP on Saturday, 8 December, 2012

Latin American Minerals Inc.  announces the commencement of CSAMT geophysical surveys at the Paso Yobai Project in Paraguay, an early start to the 2013 exploration campaign to drill the project’s multiple geochemical gold targets. The ground-based geophysical survey will initially focus on the X-Mile Trend prior to covering the Discovery Trend and multiple outlying target areas. The intensive geophysics program is expected to require 2 to 3 months. To follow up the initial deep reconnaissance survey results, the Company will implement the second phase of the program with targeted diamond drilling, expected to start by mid-February 2013.

CSAMT (Controlled Source Audio Frequency Magneto-Tellurics) is a rapid, high-resolution variant of the magneto-telluric class of geophysical surveys, designed to provide detailed section views of lithology and structural features, and to delineate any contrasting zones of hydrothermal alteration. The geophysics survey contract was awarded to Canadian company Quantec Geoscience Limited after a competitive bid process. Quantec is the world leader in deep magneto-telluric and electrical survey technologies for mineral exploration.

Miles Rideout, President and CEO of the Company, stated, “We have seen CSAMT surveys employed with excellent results on many gold systems over more than two decades. Applying this imaging technology at Paso Yobai, prior to drill testing many of our surface gold targets, will allow us to employ better structural information in the initial drill targeting, and will extend our targeting ability to more than 300 metres depth. The high resolution of CSAMT will allow us to better understand the nature, depth and orientation of major mineral targets. The potential benefits to the Paso Yobai gold project include: increased exploration depth, improved drill target identification, reduced reconnaissance drilling cost and improved target prioritization.”

About the Paso Yobai Gold Project:

The Paso Yobai Project is a 15,020 hectare exploration and mining property with multiple large gold showings mapped at surface. The two primary gold bearing structures at Paso Yobai include the 4500 metre Discovery Trend and the 14,800 metre X-Mile Trend. Additional oblique trends and outlying gold zones have been delineated by the Company’s work programs, producing a gold system footprint approaching 100 sq. km. in area.
