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.

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

Posted by on Tuesday, 18 October, 2011

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

To view “Figure 1. 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:

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”.

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.


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.

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.”
