Ground gravity survey in the Ring of Fire

Posted by on Tuesday, 28 February, 2012

MacDonald Mines Exploration Ltd. announces results of a ground gravity survey over the Company’s VMS targets on the Butler Property in the Ring of Fire.

The presence of density anomalies associated with and adjacent to the feeder/stockwork sulphides intersected to date on Butler 3 suggests either:

  • An  increased presence of sulphides or
  • A different rock type of greater density or
  • a combination of both

The measurement of gravity is an effective technique for defining geometry, structure, and a proven tool in mapping intrusions in sedimentary and volcanic terrains. The use of ground gravity surveys, have historical success in the search for volcanogenic massive sulphide (VMS) deposits.  The technique has been attributed to the discovery of the Sunridge Gold Embra Derho deposit in early 2007 (Approx 62.5 m/tonnes) in Eritea.

The gravity data collected over the Butler property by the Ontario Geological Survey (“OGS”) and Geological Survey of Canada (“GSC”) survey confirmed the Company’s interpretation of a large mafic – ultramafic package that exists along the eastern portion of the property (Butler 5).  This insight prompted MacDonald to utilize the technique over the highly prospective Butler 3 zone.

Ground Gravity Survey

At Butler 3, three distinct density anomalies coincident with anomalies from other geophysical techniques have been identified by Abitibi Geophysics.    These density anomalies add credence to the interpretation of a large VMS system in the Zone identified as Butler 3.  This system is associated with the stringer materials in diamond drill hole BP11-Cu06 which intersected 167 metres of 0.39% Cu and 1.13% Zn. Results for Butler 4 and Butler 5 are pending and data collection continues as exploration is ongoing.

Butler 3 – Characteristics of a Volcanic Hosted Massive Sulphide Deposit (VMS)

The Butler 3 targets are quantified by the following geological characteristics:

  1. The volume of alteration is exceptional, indicating that a very large volume of hydrothermal fluid discharged in this region.
  2. Butler 3 is contained in a felsic-dominated sequence.
  3. The alteration zone is Cu-enriched, and the Cu content increases stratigraphically upwards towards the mineralized horizon.  Cu tenor is high (greater than 3%).
  4. Zinc mineralization is less than expected – indicating a higher temperature system (Cu-enrichment).

Geophysically the targets have physical properties commonly identified with massive sulphides.  These are:

  1. The Butler 3 targets are Electrically Conductive – indicative of metallic content.
  2. Elevated magnetic susceptibility – signifying structure and potential sulphides.
  3. Dense – suggesting the presence of sulphides.

In summary Butler 3 exhibits a multitude of exploration vectors and proximity indicators of a VMS system.  These include but are not limited to:

  • Geophysical properties – conductive, dense, magnetic.
  • Mineral zonation – stringer mineralization with elevated Cu values have been intersected over significant lengths.
  • Alteration Indicies – the drilling has identified a large alteration system with sodium depletion.  This is an indication of lateral distance from the core of the discharge zone.
  • Mineral chemistry vectors – these are coincident with the geophysical anomalies (conductance and density)
  • Structural controls – the stringer zone is capped by a key marker horizon comprised of a siliceous relatively impermeable, black felsic unit

Deep Penetration and High Resolution IP Resistivity Survey

Insight Geophysics Inc. has been retained to apply their technology over Butler 3, Butler 4, Butler 5 and the Sanderson properties in the Ring of Fire.  This array is currently being utilized in the Ring of Fire by Noront Resources who have commented on the success of the technique to identify zones of nickel sulphide in their recent press release.

Preliminary results of this survey over Butler 3 have confirmed chargeability anomalies coincident with the gravity results.  Chargeability measures the ability of the sub-surface to temporarily maintain an electrical charge – sulphides are typically chargeable.  The survey is expected to be completed in early March, 2012.

Large IP Anomaly at Baffin Island Gold Property

Posted by on Friday, 3 February, 2012

Commander Resources Ltd. announces that results from the deep sensing, 3-D Induced Polarization (IP) Survey conducted at the Kanosak gold prospect in the 2011 field season have been reported. The survey results indicate the presence of a steeply dipping, cross-cutting zone of high chargeability and low resistivity below gold anomalous strata bound sulphide mineralization hosted in flat lying sediments over a 3 km strike length. The IP anomaly is interpreted as a possible feeder to the extensive surface mineralization. Trenching and shallow drilling has previously found widespread free gold in quartz veins and associated with disseminated arsenopyrite and pyrite.

The survey was conducted by Abitibi Geophysics of Val d’Or, Quebec, who also prepared all plans and interpreted the results. The report states that a large, sub-vertical anomaly commences about 150 metres directly below the surface gold showings at Kanosak. The IP chargeability anomaly underlies the entire 3 km strike extent of the grid. Additionally, the anomaly is open to the south, with the strongest response at the southern most grid line.

The report states that the intensity of the anomaly increases with depth, with primarily background chargeability values (15-30 mv/V) from surface to 50 metres, increasing to some of the highest recorded values (300 mv/V) at 150 metres. The high values are interpreted to be attributable to sulphides, as there is no graphite recorded in this area.

The IP results are presented with maps on the Company’s website. Three plan maps show chargeability values at 50-100-150 metre depths and a surface interpretive plan shows the IP anomaly, along with completed and proposed drill holes. Most of the holes (shown in grey) were drilled west of the target or were too shallow to reach the top of the interpreted source. This previous drilling was designed to test surface gold showings and early stage, shallow (less than 75 metre depth) IP response. Proposed holes, (shown in green) are designed to test the new, deep responses.

The interpretation of the IP response from the deep, 3-D survey indicates that a very large, strong disseminated sulphide source dips sub-vertically below 150 metres depth from surface. This may be the feeder system which produced the very high grade, but irregularly distributed gold veins scattered over 3 km’s on surface at Kanosak.

The chargeability anomaly is associated with a resistivity high, which is also reflected in the surface showings at Kanosak. Here, gold is associated with the arsenopyrite and minor pyrite, which are good IP sources. As the IP source is associated with magnetic lows, the source is not expected to be magnetic pyrrhotite or magnetite.

A 3,000 metre drill program has been proposed to test these strong, deep targets. A camp is established and permits are in place.

Testing IP anomaies on Rice Lake Gold Belt, Manitoba

Posted by on Monday, 23 January, 2012

Harvest Gold Corporation announces that a diamond drilling program is set to commence on its 100% owned CUD claim Property, located 8-kms east of San Gold’s operating gold mine in the Town of Bissett, Manitoba.

The drill program will test two strong Induced Polarization (IP) geophysical anomalies associated with a shear zone developed within volcanic rocks of the Rice Lake Gold Belt. The favourable volcanic package that hosts the San Gold 1 zone and San Gold # 2-3 zones extends onto our property.

A 9.3 km IP survey was completed last summer by Abitibi Geophysics outlining six strong chargeability anomalies (C-01 to C-06) and four discrete anomalies (C-07 to C10). The most promising targets are C-04 and C-05 which form a somewhat continuous east-west trend across the grid. Anomaly C-04 is the strongest chargeability anomaly observed on the property.

A prospecting program was completed in the fall, following up the IP targets recommended by Abitibi Geophysics. The C-04 IP anomaly comprises quartz vein material within a silicified and sericitized altered shear zone. Two holes are planned to test the strongest conductivity sections of this target (see Figure 2).

Downhole Geophysical Survey on Magistral Deposits in Peru

Posted by on Wednesday, 26 October, 2011

Trevali Mining Corporation announces the results of an in-hole geophysical survey (DownHole ElectroMagnetics – DHEM) designed to image and target the geophysical responses from the Magistral deposits at depth and along-strike. Results of the survey conducted by Val D’Or Geophysics are interpreted to reflect the presence of a large mineralized body extending approximately 500 metres from known mineralization in the Magistral Deposits including drill hole SAN-173 which intercepted high-grade silver-lead-zinc mineralization at approximately 450 metres below the Magistral North deposit at 750 metres vertical depth (see NR 11-26 for details).

Six drill-holes were surveyed for a total of 7,914 metres using a 21-channel Crone EM Transmitter/Receiver unit with readings collected every 10 metres.

Petrophysical modeling – that is the measurement of the geophysical properties and characteristics of representative geological units and known mineralization (magnetic susceptibility, electromagnetic conductivity, galvanic resistivity and chargeability) – was also measured to aid in subsequent modeling and interpretation.

The DHEM results display a strong correlation (direct relation) with mineralization (pyrrhotite gangue) within which significant quantities of zinc-lead and silver mineralization occur in the defined Magistral deposits (Figure 2).

To view the two Figures associated with this News Release, please click the following link:

The geophysical response (EM) in the three deepest Magistral holes drilled to date (SAN-0170, 0173 and 0174 – see NR 11-26 for details) is constant and suggests the presence of a large geophysical conductor at depth and extending from and to the south-east for approximately 500 metres (Figure 1 & 2). The core of geophysical anomaly as presently defined is centred to the south of Magistral North and below the Magistral Central and South deposits suggesting that mineralization may merge at depth.

It should be noted that the geophysical anomaly remains open – the size of the anomaly and the distance it can be imaged or ‘seen’ is a limitation of the geophysical method – simply the amount of power available to charge the conductive body.

While the presence of a large geophysical anomaly spatially associated with known mineralization is encouraging the Company strongly cautions that the anomaly requires drill testing and geochemical analysis of any results in order to confirm whether significant mineralization may be present – no value may be assigned to the anomaly at this juncture in time – that is it remains an early stage exploration target.

Two exploration holes are currently targeting the anomaly at approximately 600-700 metres vertical depth and contingent on results additional drilling and geophysical surveying may be required going forward.

Property Background

The former Santander Mine is classified as a polymetallic High Temperature Carbonate (HTC) or Carbonate Replacement Deposit (CRD). Modern mining activities commenced on the principal Santander Pipe from 1958 until 1991 to an approximate depth of 480 metres.

Total production is estimated to be about 8 million tonnes averaging +7% zinc, 1 to 4% lead and 60 g/t silver with additional copper credits. Mineralization remains open at depth with reported zinc grades of 11% in multiple replacement or manto bodies.

An initial due diligence study in late 2007 undertaken by the Company confirmed the high-grade nature of the former producer with values up to 39.8% zinc, 8.98% lead, 324 g/t silver and 1.6% copper (see NR-07-01 for details) determined through re-sampling of outcropping mineralization and historical drillholes.

Typically, such Carbonate Replacement Deposits (CRDs) comprise multiple lens and orebodies and have the potential to form significant mining camps.

The 4,455-hectare (44 km2) property contains numerous outcropping polymetallic mineralized bodies (Magistral North, Central, South and Puajanca South).

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.

Mag/IP anomalies in Red Lake

Posted by on Monday, 20 June, 2011

Abitibi Geophysics presented the results of its walking magnetic survey and its IP survey that utilized its advanced “3D – IPower” technology. The presenters focused on two primary land based targets, one on each of the Dome and McManus properties.

Significant results of the geophysical work include the identification of the highest priority target of a zone at the north east part of the McManus patents claims of anomalous chargeability 810 meters in strike length by 330 meters in width by 450 meters in depth which may extend deeper as the IP’s survey‘s limit was to a depth of 450 meters is coincident with structural and lithologic projections based on observed alteration, veining and sulfide mineralization.

Much of the Property overlies a large quartz diorite intrusion which is host to several past-producing gold mines and numerous gold occurrences. In addition, diamond drilling and surface exploration by Sabina Resources Limited and Wolfden Resources Limited (Press Releases – 2005) reported significant high grade gold mineralization from their Follansbee Property, located about 2 km north of the Property. Sulphide associated gold with values as high as 5.05 g/t Au over 34.95 m occur in metasedimentary rocks in contact with metavolcanic rocks of the Balmer Assemblage. This significant new discovery represents a previously unrecognized environment for gold mineralization in the Red Lake Camp. This suggests that opportunities exist for the discovery of gold in areas previously thought to be non-prospective. It is important to note that there are two sequences of metasedimentary and metavolcanic rocks inferred to occur within the northwestern portion of the Property under Red Lake (that may be associated with a possible projection of the unconformity between the Confederation assemblage rocks and the older Balmer assemblage rocks) and within the southernmost portion of the Property. These areas should be considered as key targets for any future exploration program.

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.

Geophysical Survey to Commence on historic Regcourt Gold Mine

Posted by on Monday, 9 May, 2011

Galahad Metals Inc. announces that a cut-grid has been established in the area of the historic Regcourt Gold Mine shaft and Abitibi Geophysics Ltd. of Val-d’Or, Quebec is slated to complete a ground IP survey of the area by mid-May. These data will be integrated with the existing down-hole, 3D-IP survey data obtained this past winter. A second grid will be established over a granodiorite intrusion underlying the eastern part of the Regcourt Property in preparation for an upcoming, detailed exploration programme.

In addition, Phase II diamond-drilling is proceeding on schedule and has intersected the targeted hydrothermal quartz-tourmaline veins and stringers associated with fractures and shear-zones, in the first four (4) holes of the program. Assay results are pending.

The Regcourt Property consists of 53 claims covering over 32 km2 in the eastern part of the Abitibi Greenstone Belt. The 2010-2011 exploration programme is designed to: 1) corroborate historic drill- and underground-intersections around the abandoned Regcourt Mine; 2) to validate the historic resource of 61,000 tons of 6.49 gpt Au, and; 3) to expand the dimensions and volume of the resource.

These historical estimates provide a conceptual indication of the potential of the property and are relevant to ongoing exploration.

The Regcourt Property hosts a small gold deposit discovered on surface by trenching in 1944. During this early prospecting period erratic gold values were obtained from a stripped outcrop exposing the veins yielding an average grade of 8.13 g/t gold over an average width of 0.76meters along a strike length of 67 meters. Subsequent work and drilling indicated an historical tonnage of 61,000 tonnes grading 5.49 g/t gold (1983, non NI 43-101 compliant). This deposit is hosted by a granodiorite stock which intrudes mafic to intermediate volcanic of the Malartic Group. Geologically the mineralization is described in the records as fracture-filled quartz-tourmaline veins and veinlets containing fine grained pyrite and free gold similar to other Quebec gold deposits such as to Beaufort Mine owned and operated by Richmont Mines.

Induced Polarization Geophysical Work at the Dome Property in Red Lake

Posted by on Friday, 15 April, 2011

Sphere Resources Inc. along with its partner Duncan Park Holdings Corporation  in the Dome project have completed the survey of geophysical ground magnetics and the revolutionary IPower 3D induced polarization conducted by Abitibi Geophysics. The data, which is being transferred into a 3D model, will form the basis for selecting priority targets for a diamond drill program in the coming months. The analysis of data in the 3D model should be ready to review in about 3 weeks.

The Company is currently organizing a field crew and driller for the upcoming Phase 1 drill program. The drilling program should commence in late spring or early summer on targets on the land based claims and any targets on the water based claims will be drilled when ice conditions on the lake are favourable for safe drilling.

RED LAKE Dome Gold Project:

The Dome property consists of 16 unpatented mining claims that cover approximately 500 hectares within the townships of Dome, Heyson and Byshe. The Property is located about 1 km east of the Town of Red Lake and 3 km southwest of Balmertown, Ontario, located in the Municipality of Red Lake, Ontario.

Much of the Property overlies a large quartz diorite intrusion which is host to several past-producing gold mines and numerous gold occurrences. In addition, diamond drilling and surface exploration by Sabina Resources Limited and Wolfden Resources Limited (Press Releases – 2005) reported significant high grade gold mineralization from their Follansbee Property, located about 2 km north of the Property. Sulphide associated gold with values as high as 5.05 g/t Au over 34.95 m occur in metasedimentary rocks in contact with metavolcanic rocks of the Balmer Assemblage. This significant new discovery represents a previously unrecognized environment for gold mineralization in the Red Lake Camp. This suggests that opportunities exist for the discovery of gold in areas previously thought to be non-prospective. It is important to note that there are two sequences of metasedimentary and metavolcanic rocks inferred to occur within the northwestern portion of the Property under Red Lake (that may be associated with a possible projection of the unconformity between the Confederation assemblage rocks and the older Balmer assemblage rocks) and within the southernmost portion of the Property. These areas should be considered as key targets for any future exploration program.

Results of IP Survey at Cache River

Posted by on Saturday, 19 February, 2011

Wolverine Exploration Inc. announces an update to the ongoing exploration program on its Cache River copper-gold property in Labrador.

The final report on the recently completed induced polarization (IP) survey by Abitibi Geophysics has been received and reviewed by Wolverine. The report outlines a number of chargeability anomalies that require follow-up by prospecting and drilling. Some additional IP work is suggested to further outline newly detected targets that are open along strike and extend beyond the survey grids.

The Abitibi report outlines a chargeability anomaly (CR1-01) on Grid One that is located adjacent to an airborne electromagnetic (EM) conductor that was detected from a 2007 AeroTEM survey and is located close to previous drillhole DDC04-10. Further prospecting will be undertaken to establish the strike extent and composition of this combined EM-IP target. The CR1-01 anomaly extends from Line 68,800E to 70,600 on Grid One for a strike length of 1.8 km and is present on 13 of 19 survey lines. A second target CR1-05 is located approximately 650 m north of CR1-01 and extends for a strike length of 1 km as an anomalous chargeability response continuous on 10 of 11 survey lines. CR1-05 is a Priority One target. A third target CR1-06 is located about 150 m south of CR1-05 and extends for a strike length of 1.5 km, also a Priority One target.

On Grid Two are located several chargeability anomalies with high associated resistivity that is more suggestive of bedrock sulphide conductors than overburden. These targets are generally shallow (within 10 – 15 m of surface) and could be targeted by shallow drilling. Anomalies CR2-06 and CR2-07, for example, have strike extents of 1.3 km and 1.0 km respectively and are both Priority One targets. Both anomalies are open to the southwest and extend beyond the survey grid.

Also on Grid Two are a series of chargeability anomalies (CR2-01, CR2-02 and CR2-03) that are located in close proximity to previously discovered malachite showings in rock cuts along the Trans Labrador Highway. These three anomalies could represent copper-carrying sulphide mineralization that has leached out the malachite. These anomalies are all open to the northeast ad have strike lengths ranging from 325 m to 900 m.

The Abitibi report recommends a total of 11 drillholes (or 600 m of drilling) to test the best targets with additional trenching and more IP surveying to fully delineate IP anomalies that remain open along strike or are still unexplained. Ground-checking is recommended prior to drilling to ensure the proposed drill collars can be accessed.

Commenting on the report, Wolverine President & CEO Lee Costerd commented, “The report has identified specific areas that can be directly targeted by drilling. These targets could represent disseminated sulphide carrying copper and gold. This is our target at Cache River and we intend to follow-up with a drill program to test all the targets that have been identified from this survey.”

Wolverine is currently negotiating the drill contract and will plan to test the IP targets as early as March 2011.

IP/Resistivity Geophysical Survey on Ti-Pa-Haa-Kaa-Ning

Posted by on Friday, 4 February, 2011

Abitibi Geophysics of Val-D’Or, Quebec, has re-mobilized to Ti-Pa-Haa-Kaa-Ning project (Rainy River and Northern Superior)  to complete the 80 line-kilometre Induced Polarization (IP)/Resistivity Geophysical Survey. This survey will cover diamond drill Targets 1–4, with a 100-metre line spacing. Severe winter cold has slowed progress however crews should complete the survey within the next 10 days.

The property is located approximately 470 km northeast of Thunder Bay and 190 km northeast of Pickle Lake, Ontario. The property is located in the Traditional Area of the First Nations Community of Neskantaga, which is situated about 30 km southwest of the Property on the southwest corner of Attawapiskat Lake.

Borehole InfiniTEM® survey

Posted by on Saturday, 11 December, 2010
Puma Exploration  provides an update on the current exploration program undertaken on the company’s Turgeon Copper property (New-Brunswick). Following
the drilling of hole F10-01, Puma conducted surface and borehole geophysical surveys to better characterize the geophysical signature of the copper and zinc lenses and to define first priority targets to be drilled in December, 2010.

Three holes were surveyed during the geophysical InfiniTEM® survey for a total of 1,261 meters. The first priority targets selected consist of Off-hole anomalies located near mineralized intercepts. For example, the survey conducted in hole F00-01 indicates that at a depth of 190 meters the drill hole intercepted only the edge of a good conductor located 10-20 meters away and extending down-dip. The assay result at that depth was of 3% Cu over 9.5 meters within a zone of 2.3% Cu over 19.3 meters.

Other drill targets were defined by the surface geophysical survey (6.7 km-line) and are located  within 100 meters from surface. From the seven  surface anomalies defined, the first one to be drilled is in strike with known copper mineralization along a favourable fault contact that is  extending for more than 600 meters. This geophysical anomaly, extending for more than 100 meters, has never been tested and is open down dip.

The deposit consists of four lenses of rich zinc-copper mineralization, which outcrop on surface. By way of example, drill intersections with 12.4% Zn and 1.8% Cu over 8.7 metres, and 10.7% Zn and 0.7% Cu over 10.1 metres have been encountered in one of the zinc-rich lenses. Spectacular copper intersections are also found, e.g., holes E82-77 with 2.5% Cu over 34.1 metres, E82-54 with 2.7% Cu over 36.2 metres, and E82-46 with 7.9% Cu over 7.5 metres. The massive to semi-massive mineralization, consisting mainly of chalcopyrite, pyrite, and sphalerite, is located in basalts forming the uppermost portion of an Ordovician ophiolitic complex.

Geophysical program on the Duquesne-Ottoman property in Quebec

Posted by on Thursday, 2 December, 2010

Xmet Inc. reports that both airborne and ground geophysics surveys will be completed on the Duquesne-Ottoman property during the month of December. A detailed helicopter airborne geophysics survey will be completed by Geophysics GPR International Inc of Longueuil, Quebec using a GPS controlled flight line spacing of 100 meters across the entire property. This survey will be flown in conjunction with a larger, more regional survey being flown by Osisko Mining Corporation (TSX-OSK) and its partner Clifton Star Resources (TSXV-CFO). The survey will utilize the advanced TDEM EMosquito II high resolution time domain transient electromagnetic system that will provide deep penetration. A Geometrics high resolution caesium magnetometer will also be utilized to provide detailed magnetic coverage. Final products will be generated by experienced geophysicists. This survey is meant to provide refined direct detection of gold-bearing conductive sulphide zones and will improve geological and structural interpretations of known gold deposits along the Porcupine-Destor Fault.

The airborne survey will be followed by a detailed ground geophysics survey targeting high grade gold mineralization associated with disseminated sulphides at Xmet’s Nip Zone (see Xmet news release dated September 24, 2010). A hole to hole 3-D IP survey will be completed by Abitibi Geophysics of Val D’Or, targeting gold mineralization surrounding drill holes DQ-09-09 (5.25 g/t Au over 16.5m), DQ-10-17 (2.95 g/t Au over 17.0 meters), DQ-02-09 (9.00 g/t Au over 3.00m) and DQ10-18 (5.60 g/t Au over 3.00 m). The down-hole IP survey targets a radius of up to 400m around the mineralization as well as beyond the end of the hole. Future drill holes planned at the Nip zone will test all major IP targets generated by this survey.

Mag for Iron-T Vanadium Project at 11630000 Tonnes

Posted by on Sunday, 21 November, 2010

Apella Resources Inc.  announces that Abitibi Geophysics Inc. from Val d’Or, Quebec has completed the contracted 250 line km Magnetic-GPS survey on Apella’s Iron-T Vanadium-Iron-Titanium project near Matagami, Quebec.

Patrick D. O’Brien, ICD.D, Apella’s CEO stated, “This survey is expected to increase the number of drill-ready targets significantly.”

The magnetic survey comprised approximately 250 km of transversal lines, base lines and tie lines over the entire western part of the property from Shallow Lake to the Bell River. This represents about 50% of the total area of the Iron-T Project. The central part of the Iron-T which was the subject of the 2009-2010 exploration drilling campaigns, as well as the eastern part, have been surveyed by Apella over the years from 2007 (17 original claims) to March 2010.

Now that this survey is complete the entire Iron-T project consisting of 146 claims totaling 3,995.57 hectares has been covered by ground magnetic survey.

Results of the new magnetic survey will be available to Apella around the beginning of December 2010 and are expected to provide an abundance of drill targets which collectively, once drilled, should confirm the size of this World-Class magmatic V-Fe-Ti oxide deposit(s) covering the Iron-T.

In the past, the Iron-T area was covered by a regional airborne magnetic and electromagnetic INPUT MK VI survey which was conducted in 1977. Regional magnetic data over the Iron-T project from that airborne survey was acquired at a nominal lines spacing of 200 metres and a nominal mean terrain clearance of 125 metres. In addition, the western half of the Iron-T Vanadium-Titanium-Iron property, now being ground surveyed by Apella was covered by a regional airborne gradiometric survey carried out in 1984. Magnetic data in that survey was acquired at a nominal lines spacing of 300 metres and a nominal mean terrain clearance of 150 metres. The two airborne magnetic surveys outlined a broad magnetic anomaly up to 4 000 nT above the background level which is continuous over some 25 km in a WNW direction.

To date, the ground magnetic surveys undertaken by Apella have shown a direct relationship with the Vanadium, Iron and Titanium mineralization discovered. They have also provided more precise locationing of the anomalies and more accurate shapes of the targets.

This latest ground magnetic was carried over lines at 100 spacings with readings every 2 seconds. The diurnal corrections are made with a synchronized Mag base station. Observation of the Total Magnetic Field (TMF) was recorded and will be treated with Geosoft software. The Vertical Gradient will be calculated from the TMF.

The survey was also planned to confirm the lengths and widths of a number of specific airborne anomalies. It covered a 3 km long NW oriented magnetic axis which starts near the southwest shore of Shallow Lake and which seems to joins the main magnetic axis. This magnetic “South Branch” is about 3 km long and has never been drill tested.

In other news, Apella has received from Viasat Geo Technologies Inc. all data permitting it to address a topographic map of the whole Iron T mining property. The data includes geo-referenced rivers, roads and lakes; as well as level curves at 1 m interval. The base of this topographic map is a mosaic of satellite images from Worldview-2 at 50 cm resolution. The base topographic map was released in jpeg format at a scale of 1: 25 000. The cartographic reference system used for local mapping and drawing is Universal Transverse Mercator projection for Canada (NAD 83), Zone 18.

This work will provide the exploration team with the tools necessary to prepare the longitudinal and transversal geological sections with an accuracy of 0.35 m in all directions. Those sections will be used for 3D modelling and for the ongoing resource calculations; as well as provide qualification with a better accuracy.

In addition, this topographic information will later be used by the mining engineers for future open-pit design and planning, the localisation to the concentrator and waste piles and all infrastructures necessary for a mining operation (power line, telecommunications, water supply, drainage, etc…).

The present satellite image taken in August 2010 clearly shows all drill sites and strippings made since 1998. The grid of cut lines made in 2009 is also well visible.

The Iron-T Vanadium-Titanium-Iron property is located in the Matagami area in the west-central part of the Province of Quebec, Canada, approximately 780 km north of Montreal. Matagami, situated in the administrative region of Northern Quebec, is the major town in the area and can provide housing, servicing, supplies, consumable and transport facilities including railway access for an efficient mining operation. The property is accessible via Matagami located approximately 780 km of Montreal, 250 km from Val d’Or and 185 km from Amos along regional highways. Matagami is accessible via Regional Highway 109 which links Amos to the Bay James Highway. The central part of the Iron-T Vanadium-Titanium-Iron property is located 10 km ESE of the town of Matagami. Access to the property itself is via all-weather gravel road N805 which links Lebel-sur-Quévillon to Matagami.
