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.


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

Posted by on Friday, 21 February, 2014

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

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

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

Neighboring explorer, Pele Mountain Resources (TSX VENTURE:GEM), has provided the results of an updated economic review of its Eco Ridge Mine rare earth and uranium project in Elliot Lake, Ontario. In its news release dated September 12, 2013, Pele Mountain reports the economic review concludes that the recent increase in mineral resources extends mine life and improves project economics. While this improvement is offset by a reduction in rare earth price forecasts, the net result demonstrates that Eco Ridge economics remain positive.

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


3-D seismic survey to define shape and size of unprecedented PGE mineralization

Posted by on Thursday, 17 October, 2013
Ivanhoe Mines reports unprecedented 90-metre intersection of 4.51 grams of platinum, palladium, rhodium and gold per tonne, plus 0.37% nickel and 0.20% copper, at its Flatreef exploration and development project on South Africa’s Bushveld Complex
Intercept includes a 40-metre section grading 6.88 grams of platinum, palladium, rhodium and gold per tonne, plus 0.51% nickel and 0.21% copper.

Chief Executive Officer, has announced that the company has intersected mineralization containing 4.51 grams per tonne of platinum, palladium, rhodium and gold (4PGE) over 90.64 metres (297 feet) at a 1 g/t 3PE cut-off in a recently drilled hole at the underground Flatreef platinum, palladium, nickel, copper, gold and rhodium discovery, which is part of the company’s Platreef Project in South Africa’s Bushveld Complex.

The 90.64-metre intersection in Hole TMT006 also includes:

  • a 40.79-metre (134-foot) section grading 6.88 grams per tonne 4PGE at a 3g/t 3PE cut-off;
  • additional nickel and copper mineralization grading 0.37% nickel and 0.20% copper, plus a platinum-to-palladium ratio of approximately 1 to 1, over the entire 90-metre intersection.

“This is an extraordinary drill hole,” said Mr. Friedland. “The 90-metre thickness of the intercept, which roughly is the same height as a 30-storey building, is unprecedented at Flatreef and I believe it also is without precedent in an underground platinum discovery in South Africa.

“The scale of the mineralized intercept has obvious implications for the contained PGMs and base metals in the open-ended Flatreef poly-metallic discovery. The combined grade and thickness of the PGMs and base metals mineralization seen in this hole far exceeds anything we’ve previously encountered in all of our years of delineating resources on our Platreef Project.”

The gentle dips in the Flatreef Discovery area mean that the drilled thickness approximates true thickness.

3-D seismic survey to better define shape and size of Flatreef Discovery

Ivanhoe Mines will undertake a 3-D geophysical seismic survey over the Flatreef Discovery before beginning site preparation work for the bulk-sample shaft. The seismic survey is expected to begin later this week and be completed in early November 2013.

Mr. Johansson said that it has become standard practice at many South African mines to conduct 3-D seismic surveys prior to sinking new shafts or beginning major underground developments. The seismic survey will provide Ivanhoe’s engineers with high-resolution imaging of the Flatreef mineralized zones ahead of the planned mining development.

About the Platreef Project

The Platreef Project is a Tier One discovery of platinum-group elements, nickel, copper and gold that contains the Flatreef underground deposit, on the Bushveld’s Northern Limb, north of the town of Mokopane and approximately 280 kilometres northeast of Johannesburg. The project is located on two contiguous rights, Turfspruit and Macalacaskop, which adjoin Anglo Platinum’s Mogalakwena mining operations.

In June 2013, Ivanhoe Mines filed a Mining Right Application (MRA) for the Platreef Project with the Department of Mineral Resources. A Mining Right allows a company to mine and process minerals optimally from the mining area for a period of 30 years, which may be extended upon application.

The Flatreef Mineral Resource, with a strike length of six kilometres, predominantly lies within a flat to gently dipping portion of the Platreef mineralized belt at relatively shallow depths of approximately 700 to 1,100 metres below surface.

The Flatreef Deposit is characterized by its very large vertical thicknesses of high-grade mineralization and the platinum-to-palladium ratio of approximately 1:1, which is significantly higher than other PGM discoveries on the Bushveld’s Northern Limb. The grade shells used to constrain mineralization in the Flatreef Indicated Resource area have average true thicknesses of approximately 24 metres at a 2.0 grams per tonne (g/t) 3PE (platinum-palladium-gold) cut-off grade, with an equivalent average resource grade of 4.1 g/t 4PE (platinum-palladium-gold-rhodium), 0.34% nickel and 0.17% copper. Flatreef’s Indicated Mineral Resources of 214 million tonnes contain an estimated 28.5 million ounces of platinum, palladium, gold and rhodium, 1.6 billion pounds of nickel and 800 million pounds of copper.

At the same cut-off of 2.0 g/t 4PE, the latest Flatreef estimate includes Inferred Mineral Resources of 415 million tonnes grading 3.5 g/t 4PE, 0.33% nickel and 0.16% copper, containing an estimated additional 47.2 million ounces of platinum, palladium, gold and rhodium, 3.0 billion pounds of nickel and 1.5 billion pounds of copper. Inferred mineral resource estimates, under the CIM guidelines, do not have demonstrated economic viability and may never achieve the confidence to be mineral reserve estimates or to be mined.


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.


Hawk Ridge Exploration Program Successfully Completed under the Geophysical Support

Posted by on Wednesday, 11 September, 2013

Nickel North Exploration Corp. announces the successful completion of its $5 Million 2013 integrated drilling, geophysical, and geological program at its 100% owned Hawk Ridge Ni-Cu-PGE Project in Northern Quebec. This year’s exploration program was initiated on May 26th with diamond drilling commencing on June 6th with a second drill added at the mid-season sealift. The helicopter supported program consisted of 7,330 meters of diamond drilling in 38 drill holes, complimentary ground geophysical programs (CRONE Pulse EM and “Walkmag”Magnetometer surveys) with requisite field mapping and prospecting.

This year’s program focused on two of the largest stratiform layered mineralized zones (Hopes Advance Main and Gamma) and regional exploration following up on numerous new targets selected from proprietary geophysical algorithms applied to the 2012 VTEM Airborne Survey. The diamond drilling program consisted of 38 drill holes totaling 7,330 meters. The drilling included 1,350 meters (4 drill-holes) in the historical Hopes Advance Main Zone and 1,240 meters (5 drill-holes) in the Gamma Zone, 1,300 meters (8 drill-holes) in regional exploration and 3,430 meters (21 drill-holes) in the newly discovered Falco 7 Zone.

The company’s geochemical protocol includes sampling the entire length of the drill core (greater than 7,600 samples collected) is being assayed. The geophysical program comprised of five ground Pulse EM grids and two high resolution ground magnetic surveys were completed. Bore-Hole EM geophysics was completed in all available drill holes.

In August the Company initiated a metallurgical study and a 43-101 resource study, both of which are expected to be completed in the fall of this year. The Metallurgical study is to be completed by “XPS Consulting and Testwork Services” of Falconbridge, Ontario and the 43-101 Resource Study will be completed by “P&E Mining Consultants” of Toronto, Ontario.

The Falco 7 Zone is located less than 3 kilometers from tide water in the northern portion of the Hawk Ridge Ni-Cu-PGE Belt. The new mineralized zone has a minimum strike length of 1.2 kilometer striking north-south and is over 600 meters in width with a gentle 18° eastward dip that is open at depth down dip. The zone was identified early in the season through the interpretation of the 2012 airborne VTEM survey and later confirmed from ground follow-up work which led to the discovery of surface exposures of mineralized boulders and outcrop. The zone was mapped on surface and aggressively drilled with 21 holes outlining a series of highly mineralized zones comprising ultramafic and mafic zones. Mineralization at Falco 7 is similar to what has been encountered in the other major Hawk Ridge Ni-Cu-PGE mineralized zones such as Gamma and Hopes Advance Main. However, the exception at Falco 7 is the wide spread and consistent nature of the amount of magmatic sulphide encountered; comprising of interstitial to semi massive to massive magmatic sulphides, and the zone’s near-surface, shallow dipping nature of the mineralized stratigraphy.

The company considers this year’s program a very successful exploration season. Significant progress was made in all aspects of the Cu-Ni-PGE Hawk Ridge Project including the discovery of a new mineralized zone called “Falco7″. The Company’s service providers were once again highly effective with overall cost efficiencies and project effectiveness surpassing the planned drilling meterage and was completed under budget. Assays are pending and will be announced as received and appropriately reviewed and compiled.


DRILL TEST Airborne EM TARGETS IN THE ALLEN LAKE AREA

Posted by on Friday, 1 March, 2013

Canadian Platinum Corp. announces the commencement of a drilling program to drill test two VTEM anomalies associated with the Allen Lake Magnetic anomaly in the Peter Lake Project for the presence of Cu/Ni/PGE mineralization.  The program will test the anomaly with three drill holes totaling 1000 m.

In late 2011 CPC carried out a 1513.4 km VTEM survey targeting the Swan Lake, Allen Lake and Rutherford Lake areas of the Peter Lake Property (see CPC News Release July 31, 2012). The strongest EM/Magnetic anomaly in the survey is the Allen Lake anomaly. The anomaly consist of two electro-magnetic (EM) anomalies with strike lengths of approximately 1000 m and 600 m that appear to be bounding a strong magnetic anomaly which may represent a buried mafic intrusive body, similar to that which hosts the Swan Lake mineralization. The EM conductors and magnetic anomaly have a modeled depth of approximately 250 to 300 m. A TDEM Survey confirms the presence of complex, early time conductors. Geological mapping in the area of the magnetic anomaly confirms the presence of gabbro. Samples from a prospecting program in the area magnetic anomaly assayed 0.188% Cu, 0.055% Ni, 41 ppb Pt, 49 ppb Pd. Samples from the area of the magnetic anomaly taken by previous workers and reported in assessment files give values of 905 ppm Cu and 100 ppb Pt.

President and CEO of CPC, states “Given the understanding gained by our work in identifying and delineated the Cu/Ni/PGE mineralization at the Swan Lake deposit, we consider the Allen Lake target a very strong target for the presence of a Cu/Ni/PGE deposit”

The Peter Lake Project is located in Northern Saskatchewan. The southwestern boundary of the property is approximately 240 KM north-north east of La Ronge, Saskatchewan and approximately 110 km south of Points Landing. The project is now comprised of 31 mining claims totalling 141,863 hectares of land encompassing the Swan Lake complex. This Complex represents the largest ultra mafic complex in North America. To date, Canadian Platinum has drilled 43 holes for a total of 13,316 meters. The GSC has picked the Swan Lake ultra mafic complex as the number one exploration target for platinum group metal in Canada.

During 2011, the Corporation focused on delineating the mineralization and its geological controls, and followed up on the geochemical anomalies identified in the 2010 program. Work on the claims involved detailed geological mapping of the Swan Lake grid in order to identify stratigraphy internal to the gabbro/pyroxenite. To identify structures, the area was surveyed with these techniques to define drill targets and target geometry. Examination of the surface geology and drill core was completed and drill testing of the anomalies outlined was completed.

The best assay results to date is 81.5 meters of 0.632g/t Au+Pt+Pd and 0.4803% Cu and in addition 0.276% Ni. The Swan Lake mineralization represents a polymetallic metallurgy of copper, nickel, cobalt, gold, platinum, palladium, rhodium and iridium.


Airborne EM and Magnetic Gradiometer for Palladium-Platinum-Gold Project in Timmins

Posted by on Friday, 14 December, 2012

Gold Dynamics Corp. contracted with Geotech Ltd. to complete a helicopter borne Versatile Time Domain Electromagnetic (VTEM Plus) and Horizontal Magnetic Gradiometer Geophysical Survey on the Hoyle North Palladium-Platinum-Gold Project located in Timmins, Ontario. A total of 84 line kilometers of geophysical data were acquired, flown at 100 meter spacing on the property.

Analysis of the preliminary data from the VTEM Plus indicate mineralized targets exist in the eastern portions and also a mineralized trend from the southeast to the northwest of the property at approximate depths of 200 meters. The survey also identifies a system of dykes which are very common in mineralized zones on this trend and are also common to the known geology of this area.

Further results and analysis are expected in the next few weeks. This information will be evaluated to select targets for ground follow-up in order to help prioritize anomalies for drilling.

Gary Kirk, CEO/President of Gold Dynamics Corp. said, “I am extremely pleased that we were able to contract with Geotech Ltd. who are a leader in their field, utilizing state of the art technology to help us build our base of knowledge on the Hoyle North project. With targets in hand, knowing the depth and location of these targets brings us much closer to finally drilling. The known geology common to the areas where other major international mining companies (Goldcorp, Xstrata Copper, Lakeshore Gold and Brigus Gold), whom are adjacent to our project, are currently producing large quantities of gold and other precious metals out of geologic structure very similar to what the VTEM Plus has identified in ours; is very encouraging for us.”

The Hoyle North property is contiguous to Goldcorp’s Hoyle Pond mine and is within short distances to significant resources such as Owl Creek and Bell Creek. The Hoyle North property remains relatively unexplored near to expansive mining and exploration efforts by significant companies such as, Goldcorp, Xstrata, Lakeshore Gold, San Gold, Osisko Mining and VG Gold and others.


Extending the Cu-Pt-Au zone near Sudbury with IP

Posted by on Wednesday, 31 October, 2012

Wallbridge Mining Co. of Toronto reports that it has found new copper-platinum-palladium-gold occurrences on its 78% owned Wisner joint venture with Xstrata Nickel near Sudbury. One sample, said Wallbridge, assayed 5.59% Cu and 5.39 g/t TPM (Pt+Pd+Au).

The new occurrences extend the Southwest zone trend over 80 metres along an IP geophysics anomaly that includes a 400-metre stretch that has not been drill tested. They are part of a 1.0-km-long trend of mineralization and anomalous geophysics that is along strike from Walbridge’s Broken Hammer Cu-PGE development project.

Wallbridge has defined four drill ready target areas including the immediate discovery upside surrounding the Broken Hammer Cu-PGE deposit, the large trend of anomalous mineralization at the Southwest occurrence, and two other areas with similar geology and geophysical anomalies.

Marz Kord, President and CEO of Wallbridge, stated “These new Cu-PGE occurrences along the same strike trend of our Broken Hammer deposit demonstrate the strong potential of Wallbridge’s Wisner Area Property Package, which extends over 10 kilometres of favourable geology.”

See WallbridgeMining.com for more information about the Broken Hammer project.


Testing geophysical anomalies in north-eastern Ontario

Posted by on Thursday, 20 October, 2011

Zenyatta Ventures Ltd.  provides an update on the Phase II drill program at the Albany Project near Hearst in north-eastern Ontario which started on September 1.

Three (3) drill holes, testing three separate geophysical anomalies, have been completed for a total meterage of 1400 with approximately 450 samples sent to ALS Chemex for analysis. A fourth drill hole was started today to test a strong magnetic anomaly with an associated EM conductor. The program will continue until Christmas break to test several high priority Magnetic and Electromagnetic geophysical targets identified by Geotech’s VTEM 35 airborne system in 2010. It is anticipated that 10 of greater than 30 geophysical targets will be tested by year-end.

In one of the recent drill holes four separate and extensive brecciated zones have been intersected consisting, predominantly, of variably sized granite gneiss clasts set in a fine grained black matrix of, among other minerals, graphite with trace to 1% pyrite and pyrrhotite locally. A full chemical and petrographic analysis will be completed to determine the economic significance of these newly discovered breccia zones. Breccia pipe formations are often associated with mineral deposit of varying types around the world.

Another hole, just completed, intersected a coarse grained layered mafic-ultramafic intrusion (norite-gabbro) containing 1-3% pyrrhotite and trace amounts of local chalcopyrite. The observed cumulate textures and mineralization is encouraging given that Zenyatta is targeting new magmatic sources of nickel, copper, and platinum group metals related to the Mid-Continent Rifting. This validates the original theory upon which the Albany Project was based.

The Albany Project is believed to represent a deep seated Proterozoic structure that may be related to the 1.1 Billion year old Mid-Continent Rifting. The Mid-Continent Rift is a known deep seated structural environment that hosts a number of significant mineral deposits around Lake Superior, including the recently discovered Rio Tinto’s Eagle and Tamarack Cu-Ni deposits and Magma’s TBN PGM deposit. Rifting environments around the world are host to many large mineral deposits due to a tapping of the copper-nickel rich mantle by way of the structural conduits and traps for metal transport and deposit.

The Albany Project consists of approximately 300,000 acres in 28 separate claim blocks in an area highly prospective for copper, nickel, PGM’s and other mineral deposit types of magmatic origin. The 2010 airborne system identified greater than thirty anomalies on the various claim blocks. The majority of the high priority geophysical targets are to be drill tested during this Phase II program. The Phase I drilling, from March to June, encountered very encouraging results from previously unidentified sulphide bearing intrusions, favourable ultramafic rocks and a new iron discovery as noted in the news release dated June 28.


Testing EM targets in Sudbury, Ontario

North American Nickel Inc.  announces that the 1,500 m drill program targeting modeled plates derived from a ground EM (“InfiniTEM”) survey undertaken by Abitibi Geophysics that was initiated September 14, 2011 was completed October 8, 2011.  Drilling was done by Chenier Drilling Services.

The targets tested are associated with the CJ Structure, a belt of partial melt and quartz diorite-dominated breccias with less than 5 percent pyrrhotite, chalcopyrite and pyrite in outcrop. The breccia has been interpreted as one component of a previously unrecognized embayment structure, host to significant nickel-copper-platinum group metal ore deposits in the Sudbury mining camp.

Drill holes PC-14, -15 and -16 were designed to test EM targets within the CJ Structure breccias, PC-17 to serve as a geophysics platform, PC-18 and -19 for stratigraphy and down-hole geophysics and PC-20 to test a weak ground EM anomaly at the southern boundary of the property but on-trend with the Whistle Offset Structure, host to the currently producing Podolsky nickel-copper-PGM mine.

Drill core has been logged, cut with a diamond saw and sampled for assay. Assays will be undertaken by AGAT Laboratories, an ISO-certified laboratory. Full results are expected within five weeks.

To date, three drill holes have been surveyed with a down-hole pulsed EM system by Lamontagne Geophysical Services. Three drill holes are scheduled for the survey and will be completed within 10 days.


Expanding Disseminated and Stockwork Mineralization with ground EM survey

Posted by on Friday, 16 September, 2011

North American Nickel Inc. announces that ongoing field work on its Post Creek and Halcyon properties has resulted in the expansion of the recently discovered Footwall Embayment Structure.

President and C.O.O., Mark Fedikow, states, “Our newly interpreted Footwall Embayment Structure and the area of associated stockwork and disseminated mineralization at Post Creek/Halcyon is expanding as our field work continues. The embayment now measures approximately 600 x 300 metres, and we have adjusted our 1,500 metre drill program accordingly. The drill program is now underway.”

Post Creek Embayment Structure and Associated Stockwork Zone

North American Nickel’s ongoing exploration program in the vicinity of the CJ#1 and CJ#2 zones, recently interpreted as a zone of stockwork and disseminated mineralization associated with a possible Footwall Embayment Structure, has been enlarged due to beep mat and general prospecting activities. The zone of brecciation characterized by fragments and inclusions of quartz diorite and partial melt material and mineralized with disseminated pyrrhotite and chalcopyrite, has now been observed in outcrop, historic trenches and in float material for a distance of 600 metres in an east-west direction and 300 metres in a north south orientation.

The general configuration of this zone has evolved from two distinctive linear features (CJ#1 and CJ#2) to an ovoid-shaped area of mineralized breccia that abuts, and partially encapsulates, ground electromagnetic anomalies defined by a recently completed InfiniTEM ground EM survey. In its survey, Abitibi Geophysics have interpreted the CJ#1 and CJ#2 anomalies as “massive to near-massive sulphide mineralization at approximately 55 metres below surface”. These anomalies are targets in the current drill program. See http://explorationgeophysics.info/?p=1821.

The extent of the Footwall Embayment associated zone of stockwork and disseminated mineralization on the Post Creek and Halcyon properties, the CJ#1 and CJ#2 zones and location of proposed drill holes“, please visit the following link:http://northamericannickel.com/Theme/NAN/files/Maps/POS%20QD%20Locations%20on%20GE_v001_r1y0o4.JPG.

The Halcyon property is located 35 kilometres north-northeast of Sudbury in the SE corner of Parkin Twp. at latitude 46º 48′ N and Longitude 80º 50′W. It consists of 46 unpatented mining claim units and is readily accessible by paved, all-weather gravel and bush roads. The property is situated approximately 2 kilometres north and along trend from Quadra-FNX’s, currently producing copper-nickel-PGE Podolsky Mine and is adjacent to the Post Creek property. The property is underlain by a suite of Huronian aged sedimentary rocks in uncomfortable contact with an older Archean volcanic assemblage that includes mafic and felsic volcanic rocks and iron formation. Only minimal exploration has been undertaken, although results have documented I.P., electromagnetic and magnetic geophysical targets with associated and coincident geochemical anomalies for Ni, Cu, Co, Au and Zn.

The Post Creek project is located 35 km east of Sudbury in Norman and Parkin townships and consists of 35 contiguous unpatented mining claims and one isolated claim covering an area of 688 hectares. The property is strategically located adjacent to the producing Podolsky North and Podolsky copper-nickel-platinum group metal deposit of FNX Mining. The property lies along the north-east extension of the Whistle Offset Dyke Structure which is a major geological control for Ni-Cu-PGM mineralization.


Discovery with deep-looking EM survey

Posted by on Monday, 5 September, 2011

North American Nickel Inc.  announces the discovery of a second mineralized quartz diorite offset dyke within the Whistle Offset Structure on its North Range Post Creek property in Sudbury, Ontario.

Based on the results of Abitibi Geophysics deep-looking EM surveys, it is now recognized that the new Offset dyke, CJ#2, also has a coincident electro-magnetic anomaly and the source of this anomaly is estimated to be within 55 metres of surface. The geophysical interpretation by Abitibi Geophysics is that the EM anomaly can be attributed to “massive to semi-massive sulphide mineralization”. http://media3.marketwire.com/docs/nan816_F3.pdf

President and C.O.O. Mark Fedikow states, “Continued exploration by our ground team in the immediate vicinity of our newly discovered CJ#1 offset dyke at Post Creek, has resulted in the discovery of a second Offset dyke. It occurs approximately 135 metres east of the initial CJ#1 Offset, announced in June. Prospecting and mechanical excavators have exposed additional outcrop along the trend of this new dyke which provides additional exposure to assist in the definition of drill targets for our planned September program. The new offset dyke, also discovered by NAN prospector Mr. Cecil Johnson, is now called the CJ#2 Offset.”

Post Creek Whistle Offset Quartz Diorite Dyke-New Discovery, CJ#2

The CJ#2 and the CJ#1 Offset dykes are located approximately 2.8 km north of the currently producing Quadra-FNX Podolsky copper-nickel-PGE Mine and are along the projection of the Whistle Offset structure. Significant copper-nickel-PGM ore bodies in the Sudbury mining camp are associated with Offset dykes such as those discovered on the Post Creek property.

A small outcrop with textures and mineralogy diagnostic of offset dyke material was exposed beneath the roots of an overturned tree and observed by NAN prospector Cecil Johnson during ongoing Beep Mat magnetometer and general prospecting activities. Subsequent mechanical stripping and power washing has now exposed 100 m of the east-west trending CJ#2 offset dyke.

The association between CJ#1 and CJ#2 dykes is unknown at this time. It is conceivable that these two dykes are portions of a much larger and extensive offset dyke. Both the CJ#1 and CJ#2 dykes have similar textures and lithologic associations and both are mineralized with disseminated pyrrhotite and chalcopyrite (Figure 2).

Preliminary Geologic Interpretation of CJ#1 and CJ#2

Current interpretation of the CJ#1 and CJ#2 dykes by NAN field staff, based on recently acquired geologic information; suggest the discoveries may represent the keel of an offset dyke or the footwall expression of an embayment structure. Both dykes can be described as pods of quartz diorite associated with a broad corridor of partial melt material developed during the formation of the Sudbury Intrusive Complex (“SIC”). The localization of mineralization at, or near, constrictions in the dykes and/or abrupt changes in direction will be assessed in the near future with a drill program. It is planned for September and will assess the CJ#1 and CJ#2 Offset dyke-associated shallow EM anomalies, including the seven InfiniTEM targets defined on the Post Creek property.


Yukon: the successful PGM project

Posted by on Friday, 15 July, 2011

Yukon Wellgreen project promises to be one of the largest Platinum Group Metals projects in Canada.

Geotech Helicopter-borne Versatile Time Domain Electromagnetic (VTEM) and magnetic survey flown in 2007  provided a window to bedrock geology through overburden covered areas of the property while outlining several new areas of exploration interest. A Fugro helicopter-borne Mag and EM survey conducted in 2008 demonstrated that the magnetic signature of the peridotite extends approximately 6 km on Prophecy Platinum’s ground.

Prophecy Platinum Corp.  announces the receipt of an independent National Instrument (NI) 43-101 compliant report and mineral resource estimate for its Wellgreen PGE-Ni-Cu property located in the Yukon Territory, Canada.  The independent study incorporated drill data from 701 diamond drill holes (182 surface and 519 underground) totalling over 53,222 metres. Using a 0.4% NiEq (nickel equivalent) cut-off grade, the Wellgreen deposit now contains a total inferred resource of 289.2 million tonnes at an average grade of 0.53 g/t platinum, 0.42 g/t palladium, 0.23 g/t gold (1.18g/t PGM+Gold), 0.38% nickel, and 0.35% copper. Separately, the deposit also contains an indicated resource of 14.3 million tonnes at an average grade of 0.99 g/t platinum, 0.74 g/t palladium, 0.52 g/t gold (2.25 g/t PGM+Gold), 0.69% nickel, and 0.69% copper. The resource includes both the East Zone and the West Zone of the Wellgreen project.

Widespread nickel-copper-PGE mineralization on the property is related to a swarm of Triassic aged mafic-ultramafic sills that extend over a lateral distance of 4.5 km and a stratigraphic interval of at least 1.5 km. The sills are preferentially emplaced along the contact between Pennsylvanian to Permian Station Creek Formation volcanic rocks and Early Permian Hasen Creek Formation sedimentary rocks. The sills are thickest along a northerly trending ridge that bisects the central part of the property and this area may be near the intrusive centre.

Best grades of mineralization occur in the west part of the property where relatively thin but laterally extensive sills that are elsewhere dominated by peridotite give way to a greater proportion of gabbro. Mineralization consists of disseminated sulphides in gabbro, which to date have received little attention, and banded to massive sulphide mineralization along the sheared contact between gabbro and country rock. The banded to massive sulphides are enriched in the rare PGEs rhodium, osmium, iridium and ruthenium.


THE NEW NI-CU-PGE ZONE in Quebec after Mag-EM heliborne survey

Posted by on Thursday, 16 June, 2011

Midland Exploration Inc. announces the discovery of a new mineralized zone with nickel, copper and platinum group elements (« PGE »), intersected at the end of the drilling program recently completed on its Laflamme Property.

Hole LA-11-08, drilled in the northeast part of the property to test a combined magnetic and electromagnetic (VTEM) anomaly, intersected an ultramafic rock sequence about 200 metres thick, which hosted a mineralized interval from 90.6 to 98.6 metres, grading 0.66% Ni, 0.35% Cu, 0.17 g/t Pt, 0.16 g/t Pd, 0.11 g/t Au and 1.4 g/t Ag over 8.0 metres. This zone includes a higher-grade interval, at 1.55% Ni, 0.53% Cu, 0.26 g/t Pt, 0.28 g/t Pd, 0.13 g/t Au and 1.9 g/t Ag over 1.6 metres from 91.1 to 92.7 metres. Disseminated, net-textured and locally semi-massive styles of mineralization are observed. This new zone was intersected at shallow depth, i.e. at about 60 metres vertical depth, and remains wide open in all directions. In addition, helicopter-borne magnetic and electromagnetic (VTEM) anomalies associated with the discovery extend over several kilometres and thus represent an extensive prospective area that remains completely untested.

In light of these very encouraging results, Midland and North American Palladium intend to begin an aggressive exploration campaign shortly, which will include a Pulse EM survey in hole LA-11-08, ground-based geophysical surveys, and additional drilling to assess the new discovery and to test the remaining targets across the property.

This extensive land position is strategically located between the Sleeping Giant gold mine, which has produced more than 960,000 ounces of gold to date (Source: IAMGOLD website), and the Comtois high grade gold deposit held by Maudore, where uncut inferred resources are estimated at 524,000 ounces of gold in the Osbourne and Bell zones (Source: May 2002 NI-43-101 compliant technical report by Roscoe Postle Associates Inc.).

The bedrock in the area is dominated by porphyritic, pillowed and locally magnetic basalts, cut by diorite intrusions, felsic porphyry intrusions, and a swarm of NE-trending diabase dykes. This sequence is bounded to the north by the Marest granodioritic pluton. Several major structures trending EW to ENE-WSW occur in the south part of the property.


Deep-Looking Ground Geophysical Survey on Sudbury Basin

Posted by on Saturday, 4 June, 2011

North American Nickel Inc. announces the commencement of new ground geophysical surveys at its flagship Sudbury property, Post Creek. The property is located 1.5 km northeast of Quadra-FNX’s producing Podolsky copper-nickel-platinum group element mine and covers the extension of the Whistle Offset Structure, which is the host rock to the Podolsky mine. North American Nickel has focused exploration on this property since acquisition and has recently completed prospecting, geophysical surveys and geochemical sampling programs.

Abitibi Geophysics will undertake an InfiniTEM ground geophysical survey on Post Creek. In preparation for the survey, a 35-km grid has been cut and chained and encapsulates all areas of exploration interest on the property. The survey will take approximately 8 days to complete and results are expected within a month of completion.

The purpose of the survey is to assess the Post Creek property at depths of up to 400 m for conductive targets associated with the Whistle Offset Structure and to compliment the results of shallow-looking geophysical surveys and prospecting activities that the Company has undertaken over the past several months. These deposits are typically very conductive and magnetic in character.

North American Nickel President and C.O.O. Mark Fedikow states, “The InfiniTEM survey is designed to look deeper in key areas of the property that we have identified, but where we are unable to explore using surface based Beep Mat surveys and/or historic geophysics. We have been successful in identifying multiple geological, geophysical and geochemical drill targets near surface and now have the tool to assist us in generating deeper targets at Post Creek.”

The property lies along the extension of the Whistle Offset Dyke Structure which is a major geological control for Ni-Cu-PGM mineralization.

Airborne VTEM geophysical survey results and ground IP and magnetic surveys undertaken by previous operators were obtained from the geophysical contractors in digital formats and these data will form individual “layers” for integration with geological and geochemical datasets.


Progress on Semple-Hulbert and Butler Lake properties with geophysics

Posted by on Monday, 9 May, 2011

MacDonald Mines Exploration Ltd. announces the commencement of a 3,000 meter diamond drill program on its Semple-Hulbert Property in the James Bay Lowlands of Northern Ontario. The program follows the Butler Lake drill program which consisted of 3800 metres of drilling over 17 diamond drill holes targeting volcanogenic massive sulphide (VMS), nickel-copper-platinum group element (Ni-Cu-PGE), and vanadium targets.

The Semple-Hulbert drill program will focus on high priority Ni-Cu-PGE targets in a never-before-drilled geologic complex that geophysically has been interpreted to resemble the Voisey’s Bay Ni-Cu deposit.

Semple-Hulbert Property

Drilling has commenced on the highly prospective Semple-Hulbert Property, located within the traditional territory of the Kasabonika Lake First Nation.

The Semple-Hulbert claim group was initially targeted by MacDonald’s because it had:

The strongest regional magnetic anomaly;

The strongest regional gravity feature;

Been mapped as an ultra-mafic feature on regional geology maps.

The primary catalyst for this information was a Geotech VTEM survey of the claim group in 2008, interpreted by Quentin Yarie, P.Geo., Hadyn Butler, P.Geo. and Larry Hulbert, D.Sc.

Geophysical Interpretation of Semple-Hulbert

- The geophysical data exhibits the characteristics of an intact intrusive body.

- Modeling of the magnetic data outlined a magnetic feature, which is dimensionally about >10km long by 3-4km wide and extending to at least 3km below surface.

- 8 electromagnetic targets (conductors) located within the interpreted intrusive are targeted for drilling;

- Within this body the magnetic response varies spatially – suggesting multiple geologic events.

- This interpretation fits the analogy to the Voisey’s Bay deposit; that being multiple magma pulses over time.

- The modeling also exhibits features similar in nature to four of the Voisey’s Bay intrusive components; the Eastern Deeps, Discover Hill Zone, the Ovoid, and the Reid Brook Zone (feeder sheet).

Butler Lake Property

The recently completed drill program on the Butler Lake Property consisted of 17 diamond drill holes, 7 targeted VMS mineralization, 2 targeted Ni-Cu-PGE mineralization, and 8 targeted vanadium.

VMS – (Copper/Zinc)

Stringer, semi-massive, and massive sulphides consisting of pyrite, pyrrhotite, chalcopyrite, and sphalerite were intersected in 6 of the 7 VMS drill holes. Samples have been submitted to Activation Laboratories Ltd. (ActLabs) in Thunder Bay for analysis, with assay results expected by May 16.

Nickel

Disseminated magmatic sulphides were intersected within each of the 2 Ni-Cu-PGE drill holes. Samples have been submitted to ActLabs for analysis, with assay results expected by May 16.

The Company will be conducting the next phase of drilling on the Butler Lake property once all of the current exploration data and assays have been received and analyzed.  Geochemical and geophysical signatures will be utilized to direct the drill program which is anticipated to begin in July, 2011.


HIGH GRADE INFILL DRILLING RESULTS AT EAGLE’S NEST

Posted by on Thursday, 14 October, 2010

Noront Resources Ltd. reports the remaining assay results from the infill drilling program at the Eagle’s Nest deposit at the Company’s McFaulds Lake Project in the James Bay lowlands, Ontario.

Noront’s President and CEO, Wes Hanson, states: “The Company is pleased with the results. Nickel, copper, platinum and palladium grades were higher than expected in the majority of the holes completed. Most of the holes targeted the inferred resource and the Company believes that a large percentage of the inferred resource has been upgraded as a result of this drilling.”
