Tigray Resources Inc. announces assay results from preliminary diamond drill-hole tests of the VTEM09 VMS Prospect on the Harvest Property and the Adi Gozomo Gold target on the Adyabo Project, in Northern Ethiopia. Single diamond drillholes tested both targets as an initial appraisal of prospectivity.

The results include:

  • 10.69 metres grading 3.47% copper, 4.2 grams per tonne gold, 3.69% zinc, and 91 grams per tonne silver from 19.81 metres, including 3.06 metres grading 5.75% copper, 8.00 grams per tonne gold, 0.70% zinc, and 107 grams per tonne silver (TVD001), at VTEM09
  • 7.5 metres grading 2.04 grams per tonne gold from 15.1m (AD001) at Adi Gozomo.

VTEM09 prospect

The high-grade copper and precious-metal enriched VMS mineralization intersected by TVD001 compares favourably with the metal tenor encountered at the Terakimti and Mayshehagne discoveries, and marks the third significant VMS discovery made at Harvest.

The VTEM09 prospect, located 5 kilometres ENE and along strike of Terakimti, was identified by an Airborne VTEM survey, and is characterized by a >200m strike length bedrock conductor. VTEM09 was further defined through mapping, soil sampling and trenching (refer to Tigray’s news release dated Jan 24th, 2013), and is interpreted to be a southwest-dipping, eastward-plunging mineralized VMS shoot. Additional drilling is required to test this prospect along strike, down dip and down plunge.

Adi Gozomo

One short diamond drillhole was targeted below the main artisanal workings, and encountered gold mineralization associated with the upper contact of a granodiorite hosted within mafic volcanic rocks. As the results to date indicate that gold mineralization appears directly proportional to the amount of pyrite present, additional ground exploration will be required prior to further drill testing at Adi Gozomo.

Airborne EM for VMS on ARMSTRONG BROOK PROJECT, NEW BRUNSWICK

Posted by on Friday, 31 May, 2013
The 2013 exploration program on the Armstrong Brook project commenced in early May. Highlights include the discovery of additional clusters of high-grade massive sulphide boulders in multiple locations (namely VMS Valley 4 & 5) and the completion of an airborne geophysical survey (VTEM) that identified intriguing anomalies in the vicinity of the primary boulder clusters.
The Armstrong Brook project comprises a number of high-grade polymetallic volcanogenic massive sulphide (VMS) prospects located in the Bathurst Mining Camp of northeastern New Brunswick, situated approximately 15 kilometres northwest of the Brunswick No. 12 Zn-Pb-Ag-Au deposit. Brunswick No. 12 is one of the world’s premier VMS deposits, having produced zinc, lead, silver and gold over a mine life of some 60 years.
VMS Valley 4:
The new discoveries at VMS Valley 4 occur as 2 boulder clusters located approximately 300 metres apart. Samples from the first cluster (AR13-0007-1 and 2) and the second cluster (AR13-0008-1 through 6), have returned high-grade mineralization with combined zinc+lead average assays of 13.68% and 10.33%, respectively, with impressive precious-metals as high as 459 grams per tonne silver and 1.07 grams per tonne gold. Complete assay results from the new boulder discoveries .
VMS Valley 5:
Additional prospecting has been completed in the vicinity of a recently discovered cluster of boulders located in the northwestern portion of the property. This work resulted in the discovery of 5 massive sulphide boulders in the vicinity of a discovery reported earlier in 2013, that yielded high-grade results with assays of up to 13.07% Zn, 6.07% Pb, 0.76% Cu, 251 g/t Ag and 0.66 g/t Au (see Wolfden news release dated March 20, 2013). These discoveries occur over an intermittent strike length of close to 700 metres and occur coincident to a significant geophysical anomaly that was identified in the recently completed VTEM airborne geophysical survey.
Assays remain pending for the new massive boulders from VMS Valley 5.
Preliminary results obtained from the VTEM survey indicate that the massive sulphide boulders are intimately associated with the eastern margin of a strong electromagnetic anomaly (EM conductor). This hook-shaped conductor attains a strike length of approximately 2 kilometres (see Image 1). Additionally, the cluster of massive sulphide boulders at VMS Valley 5 is centred within a broad circular-shaped magnetic high (total magnetic intensity) that has a radius of approximately 2.5 kilometres (see Image 2). Clearly, this anomaly requires detailed follow-up in the way of ground geophysical surveys prior to diamond drilling.

Drilling program after airborne geophysics for VMS

Posted by on Saturday, 8 December, 2012

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

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

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

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

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

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


The New VMS Discovery in the Ring of Fire

Posted by on Thursday, 16 August, 2012

MacDonald Mines Exploration Inc. announces results from the most recent drill program on the Butler 3 target on its Butler property located just 36 kilometres west of the Big Daddy Chromite deposit.

  • The last drill program hit zinc-rich massive sulphide mineralization with tenors typical of past and current producing VMS mines – the zinc rich sulphides are generally found on the periphery of these types of deposits
  • VMS systems typically get more copper-rich the closer one gets to the centre of extrusion
  • VMS mineralization identified on the Property suggests there are multiple centres of extrusion, and therefore the potential for multiple VMS deposits (i.e. a VMS camp)
  • Geophysics indicates there is ample room for deposits in excess of 20 MT
  • Company geoscientists believe the constraining geologic markers bounding VMS mineralization have been identified on the Property, and that future exploration should be able to vector into more copper-rich mineralization.

Butler 3 Section Showing Mineralized Zones

Geophysical Model

The current geophysical data set includes:

  • Airborne, Surface and Borehole Time Domain EM
  • Airborne and Ground Magnetics
  • Surface and Airborne Gravity
  • IP and Complex Resistivity

A model of this data constrained by the current mineralized intersections, geochemistry and geology indicates the potential of the Butler Property to host not only VMS occurrences of size but also multiple centres.Plan maps of this compilation for Butler 2 and 3 are below.

Each occurrence consists of an underlying copper-rich stringer zone that is separated by a ~20m massive black felsic “marker” flow from several overlying horizons of zinc-silver-copper massive sulfide. The footwall rocks are all intensely altered, characterized by widespread sodium (Na) depletion and more localized manganese (Mn) enrichment (typical of VMS camps like Sturgeon Lake).


Drill Program after Interpretation of Airborne EM Data on Flin-Flon (Manitoba)

Posted by on Friday, 13 July, 2012

Foran Mining Corporation announces the results of a spring 2012 regional drill program (the “Regional Program”) on its  McIlvenna Bay and Bigstone properties.

The Regional Program consisted of a total of eight diamond drill holes (2,387 metres), with four holes drilled on each of the two properties. The Regional Program was designed as an initial test of the numerous electromagnetic conductors identified from the interpretation of a helicopter-borne, versatile time domain magnetic and electromagnetic (“VTEM”) survey completed by Foran in fall 2011 (see Foran news release dated November 23, 2011).

Results for the Regional Program were positive, with sulphide conductors intersected on both properties. Pyrrhotite-dominant volcanogenic massive sulphide (“VMS”) style mineralization and associated alteration was encountered, with minor amounts of base metal sulphides and locally elevated concentrations of zinc, copper, and gold.

Patrick Soares, President and CEO of Foran commented: “Encountering VMS-style mineralization and alteration in this limited initial test of conductors is very encouraging. The Regional Program was both a technical success and an endorsement of these methods towards the discovery of new zones of VMS mineralization in Foran’s large and highly prospective landholdings surrounding our 100% owned McIlvenna Bay VMS deposit.”

The McIlvenna Bay and Bigstone properties are located in east central Saskatchewan. The 20,382 hectare (“ha”) McIlvenna Bay property, which hosts Foran’s McIlvenna Bay deposit, is located 65 kilometres (“km”) west of Flin Flon, Manitoba. The 11,126 ha Bigstone property is located a further 25 km to the west. Past exploration by previous operators on the Bigstone property has outlined zones of both copper- and zinc-rich VMS mineralization, including a 2002 historic mineral resource at the Bigstone deposit.

The Regional Program was conducted between April 9, and May 5, 2012, following the successful completion of a winter 2012 drill program on the McIlvenna Bay deposit (see Foran news release dated June 4, 2012). The Regional Program was helicopter-supported due to unseasonably warm weather though the winter and spring.

McIlvenna Bay Property

Four holes (1,211 metres) were drilled to test VTEM conductors on the McIlvenna Bay property; the holes were collared 1 to 7 km away from Foran’s McIlvenna Bay deposit (Figure 1).

To view Figure 1: Location of Regional Program drill holes, please visit the following link:http://media3.marketwire.com/docs/FOMF1.pdf.

Drill holes MR-12-01 and -02 targeted stratigraphically discordant VTEM conductors up to 2 km east and southeast of the McIlvenna Bay deposit, within interpreted hangingwall stratigraphy. Both holes intersected iron sulphide-bearing iron formation and felsic tuffs with trace amounts of sphalerite and chalcopyrite. No significant assay results were obtained (Table 1).

Drill holes MR-12-03 and -04 targeted north-trending conductors with coincident magnetic highs. The holes were collared 830 metres apart and approximately 7 km southwest of the McIlvenna Bay deposit. Volcanic stratigraphy intersected in both holes appears to be upright, west facing and bimodal-pyroclastic in character. Intervals of iron sulphide-mineralized carbonaceous mudstone, siliceous exhalite and attendant silica-carbonate-amphibole+/-magnetite alteration were intersected in both drill holes. Sulphide mineralization consists principally of banded and brecciated pyrrhotite with local semi-massive (up to 35%) sulphide. These intervals contained lesser amounts of pyrite, with trace amounts of sphalerite and chalcopyrite. Locally elevated gold concentrations in the sulphide zones ranged up to 870 ppb Au (0.87 g/t Au) over 0.73 metres in MR-12-03, within a broader interval averaging 236 ppb Au (0.24 g/t Au) over 8.17 metres.

Bigstone Property

Drilling on the Bigstone property consisted of four holes (1,176 metres) targeting three north-south oriented VTEM conductor trends in the northern part of the property. This target area was previously tested in the 1970’s and 1980’s by predecessor companies and referred to historically as the Freeport Zone.

Regional Program drilling intersected iron sulphide-rich mineralized horizons in three of the four holes drilled, all of which contained traces amounts of sphalerite and chalcopyrite. Sulphide host rocks are felsic volcanic, within intermediate to mafic dominated volcanic stratigraphy.

Drill hole BG-12-01 tested the westernmost conductor trend. No significant base metal sulphide mineralization was noted in this hole, which ended in granite at a downhole depth of 324 metres.

Approximately 170 metres northeast of BG-12-01, drill holes BG-12-02 and BG-12-03 were drilled from a common collar location. These holes intersected several massive pyrrhotite-dominant sulphide horizons, each approximately 1 metre in downhole thickness, within an overall iron sulphide-mineralized felsic volcanic package ranging from 12 to 23 metres true thickness. In holes BG-12-02 and BG-12-03, iron sulphide mineralization began at downhole depths of 158.82 metres and 216.79 metres, respectively, and contained trace to 1% sphalerite-chalcopyrite within massive, semi-massive and finely laminated to disseminated pyrrhotite and lesser pyrite. Massive sulphides occur as a fine- to medium-grained matrix to rounded and sub-rounded felsic volcanic clasts. Footwall alteration to this zone is moderate intensity fracture- and foliation-controlled black chlorite.

Drill hole BG-12-04 intersected approximately 2 metres of semi-massive to massive iron sulphide starting at a downhole depth of 198.9 metres. Rounded felsic volcanic clasts occur in massive pyrrhotite with lesser pyrite and trace to 1% sphalerite-chalcopyrite.

Past exploration by previous operators on the Bigstone property has outlined zones of both copper- and zinc-rich VMS mineralization. In 2002, Aur Resources Inc. outlined a mineral resource at the Bigstone deposit in the southern part of the property, with 1.45 million tonnes grading 2.90% Cu in a copper-rich zone and 308,000 tonnes grading 11.2% Zn in a separate zinc-rich zone. The Bigstone deposit mineral resource is historic and the Company is not treating it as current; Foran has not done sufficient work to classify it as a current resource estimate. A program of drill hole re-surveying, re-logging and drill core QAQC is required to qualify the historic resource and identify areas for expansion through exploration drilling. The Bigstone property is subject to a back-in held by Teck Resources Ltd.


Mining IQ: airborne TEM for VMS discoveries

Posted by on Friday, 1 June, 2012

Mining IQ recently interview Neil Richardson, P. Geo. Chief Operating Officer. In this interview Neil speaks frankly about new advancements in exploration technology as well as the impact of VTEM on their current projects.

What is your role at VMS and experience?

I am the COO and oversee all the exploration for VMS.  I have over 24 years’ experience in the exploration and mining business – in Manitoba as well as Ontario. I have also worked in the volcanic terrain up in Manitoba for the last 18 years.

How and why did you embark on a career in mining?

I started off in a small mining town and got involved in staking claims and helping the guys blaze and cut lines and that got me interested in the geology side of things. From there I went to college and got my geology certificate and my career in the industry.

In terms of exploration – can you comment on insights from your current projects?

With respect to our Reed Copper project – which is our flagship project – we are currently under JV with HudBay Minerals. Percentage wise it splits 70% them and 30% us. We are carried to production in that project, and have recently announced a preliminary feasibility study that came out early earlier in the year.  We are delighted to have shown the project is robust, so we are looking forward to production in early 2014 and reaping some of the benefits for the next 6-7 years of production.

Are you using VTEM technology on these projects and why?

The Reed Copper deposit was a VTEM(Versatile Time-domain electromagnetic) anomaly discovery. There are lots of systems out there (we use Geotech’s platform) to choose from so you have to determine which one is right for you. What mattered to us was a good noise to data ratio so you don’t get a lot of noise in the data. We selected on that basis and continue to use it.

What is VTEM technology? And why is it revolutionizing the way you and others are conducting your exploration activities?

It works by using a very low flying and slow flying helicopter that charges a current into the ground and that current generates an electromagnetic field.

The sulphides themselves are conductors and generate their own EM field – and then when the current is cut off the sulphide bodies emit their own electrical current decay field and that’s how anomalies are measured. Where sulphides are not present, no electrical field is present, therefor no anomaly, but when you fly over a sulphide body (or even graphite) they emit their own EM field,  so you can detect these EM anomalies.

Massive sulphide bodies are very conductive and have little to no resistance. It’s like having a piece of wire except it’s in a rock mass and that’s how well the EM current will flow.

How does that affect exploration activities?

These anomalies are unusual and when we find them we are then able to plan our drilling. Graphite also is a good conductor and this presents a challenge for a geologist who has to differentiate between graphite and sulphide anomalies. There is no geophysical way to differentiate between the two types of anomalies.. However, there are a number of ways you can assess a target – look at historical drilling in the area, regional geology etc. that might help prioritise some targets.

Also a lot of the deposits are occurring with a magnetic anomaly too and you can also use that as criteria to assist you in deciding which target to drill first. So you can decide to drill where there is EM and Mag or just EM. Chances are that you will go with the EM and Mag target first.

Using this technology you are able to be more focused and targeted with your exploration activities?

Exactly.  It also helps to hone in on your property package significantly. If you are looking for VMS (volcanic hosted massive sulphide deposits) in particular areas where there are no anomalies tell you that the top 200 – 300 metres of the rock formations don’t have any EM anomalies, therefore no massive sulphides, so very quickly you can look at just focusing on select regions in your property packages. It helps with efficiency and productivity of exploration.

It tells you that there is something interesting there / something out of the ordinary and something electromagnetically is causing that anomaly and response. It could be a mix of many things – it could be a mixture of sulphide bodies, or sulphide bodies with graphite or mixture of sulphide bodies with ore bearing minerals.  If you are above the Paleozoic cover (dolomite) then you can prospect your targets, but if they are below the dolomititic rock you are forced to drill it or apply soil geochemistry over the top of the anomalies to see if you can decipher the responses.

What’s the potential for VTEM in terms of future opportunities?

It’s going to become more widely used. Lots of systems are now out there and they are all really applicable and useful. These guys will be able to generate more powerful instruments and work on the data to noise ratio – and with that in mind we might be able to see a bit deeper with more surveys. Also if we have VTEM anomalies we are able to go over the ground and do ‘time domain EM survey’s – and this means that we can generate even deeper power because you are actually on the ground generating large loops of EM current to detect deposits.

Any final tips and tricks you’d like to share based on your experience of using this type of survey technology?

No tricks but some tips…always match your survey method to your deposit model especially geophysically. If you are looking for massive sulphide you should always use EM. You might even want to look at some frequency EM surveys instead of just time domain EM but match the method to your deposit model. Also be clear on the type of target you are looking for.

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.


Down-hole and ground EM surveys for VMS in Australia

Posted by on Saturday, 18 February, 2012

Southern Cross Goldfields Limited has identified a series of new drill targets from recently completed geophysics at its Copper Bore VMS Copper-Gold Project, located 400km NE of Perth in WA, as drilling activity for 2012 ramps up.

The new drill targets have been generated from down-hole electromagnetic (“DHEM”) and surface moving loop electromagnetic (“MLEM”) surveys completed in December and January, highlighting the potential of the Copper Bore Project to host multiple accumulations of base metal mineralisation.

Details: http://www.scross.com.au/downloads/announcements/sxg20120216.pdf

Southern Gossan

At Southern Gossan, where recent drilling has extended the previously discovered zone of VMS copper-gold mineralisation, a well defined DHEM conductor has been identified immediately below previous drill hole SGRC004D, which intersected 2.6 metres @ 3.0% Cu, 0.9g/t Au, 4.2% Zn and 19.2g/t Ag from 265m down-hole.

The Southern Gossan prospect has returned a number of shallow drill-hole results over the previous 15 years (most of which did not extend below the base of oxidation). In 2011 SXG completed three reverse circulation (RC) and three diamond drill holes.

A Long Projection of these drill holes and the results of recent down-hole EM surveys completed in January 2012 shows the current understanding of the emerging VMS-style sulphide mineralisation, which has now been defined over a strike length of approximately 130 metres and to a vertical depth of approximately 280 metres.

EM conductors from ground and down-hole surveys are evident across the Southern Gossan prospect, including a well defined conductor immediately to the south of existing drilling which extends over an estimated strike length of 800m (ASX Announcement – 15 December, 2011).

This southern conductor will be tested by drilling in Q1 of 2012.

Copper Bore VMS Horizon

Project-wide ground EM surveys were completed along the entire 10km long prospective VMS horizon extending from Copper Bore to Southern Gossan in December 2011 and January 2012, resulting in the identification of several Moving Loop Electromagnetic (MLEM) conductors. A number of these conductors are coincident with aeromagnetic and soil geochemical anomalies.

Base metal mineralisation has already been confirmed at several locations along this horizon.

Importantly, a review of historic soil geochemical surveys has also identified copper anomalism parallel to the Southern Gossan-Copper Bore horizon. These new areas of interest will be followed up with new soil geochemical surveys, mapping and potentially EM.

A number of additional targets have also been generated from the project-wide ground EM surveys and acquisition of previous and recent soil geochemistry.

Next Steps

The Company has this week commenced an initial RC and diamond drilling programme to test some of these newly identified targets along the Copper Bore trend. Further drilling will also be undertaken at Southern Gossan, which is the most advanced prospect, located at the southern end of the 10km long prospective VMS horizon.

Other key activities to be undertaken by SXG at Copper Bore include:

· completing analysis of the surface EM results across the entire 10km strike of the host horizon and particularly across two aeromagnetic bullseye anomalies on the host horizon;

· completing soil sampling along the existing prospective VMS horizon; and

· undertaking soil sampling along the potential new prospective VMS horizon.
SXG’s Managing Director, Mr Glenn Jardine, said the recent work undertaken by the Company had opened up the entire Copper Bore project area, highlighting the potential for additional base metal discoveries.

“We are currently embarking on a new focused program of drilling to follow-up some of these exciting targets and further test the mineralisation at Southern Gossan,” Mr Jardine said. “We also remain confident that the comprehensive mapping, EM and soil sampling campaign may define additional walk-up drill targets to be tested later in the year.

“This is a project which is still at a very early stage in its exploration life, and we are very much looking forward to progressing it over the coming months.”

Ring of Fire – continued exploration

Posted by on Wednesday, 18 January, 2012

Bold Ventures Inc.  announces that a National Instrument 43-101 (“NI-43-101″) Technical Report (the “Bold Technical Report”) has been completed for Bold’s Ring of Fire Claims located in the northeastern portion of the Ring of Fire Area, northeast of Webequie, Ontario. The Bold Technical Report was completed by John C. Archibald, B.Sc. (Hons.) Geol., P.Geo. (“Archibald”) of Toronto, Ontario. .

Bold holds 46 claims (five groups of claims being 52, 53, 54, 55 and 56, totalling 677 claim units comprising approx. 10,832 ha.) covering high-potential airborne geophysical anomalies. The project area lies west of the Hudson Bay Paleozoic platform covering the eastern edge of the Oxford Stull Domain of the North Caribou Superterrane in the Attawapiskat First Nations (“AFN”) and Kasabonika Lake First Nations (“KLFN”) area of Ontario within the Mining Districts of Porcupine and Thunder Bay. The Bold claims are strategically located to the northeast of the main Ring of Fire structure that hosts a number of Ni-Cu-PGE MMS deposits, Cu-Zn-Pb VMS deposits as well as Cr and Fe-Ti-V magmatic oxide deposits. Prior to staking properties in this area, Bold evaluated public domain airborne Magnetic and Electromagnetic surveys that had been conducted within the main Ring of Fire structure. Since it appeared that the regional geology as defined by airborne magnetic interpretation extended as a large acuate structure and some of these structures may have influence beyond the actual Ring of Fire, Bold’s management determined this ground had potential for hosting VMS and MMS sulphide deposits. The idea was to follow-up on airborne anomalies such as that done on the Noront Resources Ltd. ground around the Ring of Fire and drill-test a number of conductors that showed high magnetic responses as well as coincident electromagnetic conductances mirroring the targets that were found at the Eagle-One, AT-12 Ni-Cu and Black Thor style chromite deposits found by Freewest Resources Canada Inc. Bold commissioned Geotech Ltd. to fly a number of their claim groups using airborne geophysics (Magnetic and VTEM-Electromagnetics).

Scott Hogg & Associates Ltd. analyzed the airborne survey results provided by Geotech Ltd., and selected at least 23 high priority anomalies on the five groups of claims. Dr. James Mungall’s two Interpretive Reports recommended diamond drilling on 12 of these anomalies for 1,760 meters to determine if the anomalies represent bedrock conductors caused by sulphide bodies that might indicate VMS or MMS type mineralized deposits.

Based on the interpretations by Scott Hogg & Associates Ltd. and Dr. James Mungall, a Phase 1 and 2 diamond drill program is recommended to test the top-12 geophysical anomalies on the five claim groups located in the KLFN and AFN Territories. The anticipated cost for this program which includes 12 drill-holes for 1,760 meters of diamond drilling is $1,833,740. Phase 1 comprised of 400 meters of drilling at a cost of $377,906 should be commenced first since an Exploration Agreement with the KLFN is in place (see Press Release dated October 27, 2011). Once an exploration agreement has been signed with the AFN, Phase 2 can proceed. Phase 2 is comprised of 1,360 meters of drilling at a cost of $1,455,834. These two programs are not dependant on one another since they are separate, discrete programs located in two unique areas of the Ring of Fire in Ontario.


Magnetic and radiometric survey in Colombia

Posted by on Thursday, 27 October, 2011

CuOro Resources Corp. announces that it has received the final data, maps, and report on the airborne magnetometer and radiometric survey which was conducted by MPX Geophysics Ltd (“MPX”) over the Company’s 100% owned Santa Elena Project, located in the Department of Antioquia, Colombia.

Highlights Include:

  • A large magnetic feature over 1km in length over the outcrops in the current exploration area
  • A new large 1km by 500m intense magnetic anomaly in the southwest corner of the property several kilometers from the current exploration area
  • Several smaller yet intensely magnetic bodies have been mapped on the Company’s northern concession

The airborne magnetometer and radiometric survey was flown with a helicopter and covered the entire 1287.5 hectare project area. Lines were orientated east-west and flown at a 50 meter line spacing with north-south tie lines every 500 meters. A total of352 line-kilometers of data were collected.

The objectives of the airborne magnetic and radiometric survey were to provide information to facilitate geological mapping and to assist in the delineation of target areas for future ground geophysical surveys and guide the current diamond drilling program. Prioritization will be the interpretation of anomalies which may represent massive sulphide mineralization.

VMS deposits typically contain pyrrhotite, an iron sulphide that is magnetic and can be detected by magnetometer surveys. Tests by Company geologists confirm the presence of pyrrhotite within the massive sulphides at Santa Elena.

Within the current area of exploration a large magnetic feature has been delineated from the southern most massive sulphide outcrops to the northern most edge of the Santa Elena Property. The magnetic feature is over a kilometer in length and is on strike with the existing massive sulphide outcrops.

A large highly intense magnetic anomaly has been mapped on the southwest corner of the property several kilometers from the current area of exploration. This magnetic feature is approximately one kilometer in length and five hundred meters in width. It is unknown whether this magnetic anomaly is part of a larger magnetic body, or if it is an independent geological feature. This anomaly warrants further investigation, and field crews will be deployed to this area immediately. No prior exploration or field mapping has been conducted in this area however recent work has discovered two new massive sulphide outcrops that are currently being channel sampled.

Several smaller yet intensely magnetic bodies have been mapped on the Company’s northern concession. These anomalies will be targeted for field exploration.

This data – used in combination with the recently completed phase one IP and resistivity survey -will greatly enhance the Company’s interpretation and understanding of the regional geology and structural system within the Santa Elena Project area, along with the identification of additional drill target areas.

Santa Elena is classified as Porphyry and poly-metallic deposits project containing 1,287.5 hectares near the north end of the Antioquia batholiths, in sequence of Cretaceous marine sediments and basaltic volcanic. Contains a large stockwork system, with an iron cap on top of the massive sulphide outcrops (Gossan) which potentially indicates an underlying porphyry system. Excellent infrastructure including paved road access, two hydroelectric plants within 5 km, and abundant water supply. Geological mapping and sampling has identified 2 VMS areas of outcropping (Azufral & Arroyo), and gossans. Ground geophysics has identified 4 strong conductors with good vertical extent, 2 of which are coincident with the Azufral & Arroyo outcrops. Artisanal underground workings exposed mineralized, sheared and brecciated mineralization with up to 2. 50% sulphides, from 0.5% to +2% Cu & from 0.2% to +1% Zn.


Airborne TEM impels VMS discoveries in Manitoba

Posted by on Thursday, 29 September, 2011

VMS Ventures Inc. announces follow-up results from the new copper zone discovery “Reed North” on its Super Zone property located 1.8 kilometres northeast of the Reed Copper deposit. The Super Zone is part of a parcel of four property packages adjacent to the Reed Copper deposit which are under option to HudBay Minerals Inc.  Reed North was previously referred to as the Super Zone Discovery.

To view “Figure 1. VTEM EM Anomalies” and “Figure 2. VTEM Anomalies with Magnetic Tilt” accompanying this press release, please click on the following link: http://media3.marketwire.com/docs/vms929i.pdf

HIGHLIGHTS

  • Hole RLE021 Intersects 3.95 m of 9.31% Cu, 1.87% Zn, 3.59 g/t Au, and 35.53 g/t Ag
  • Hole RLE022 Intersects 4.15 m of 2.16% Cu, 0.18% Zn, 0.71 g/t Au, and 8.01 g/t Ag

Neil Richardson, VMS’ Chief Operating Officer states: “The drilling results and the follow-up borehole pulse electromagnetic surveys on the Reed North discovery support our interpretation that this is a highly prospective area. The mineralization is at, and around, bimodal volcanism. This is especially encouraging as it is the setting in which the larger deposits tend to be located, in VMS camps around the world.”

The bimodal volcanism and the strong alteration over a large area suggest a large hydrothermal mineralizing system. HudBay has now drilled twelve (12) holes, for a total of 3,591 metres, on this discovery. Two mineralized horizons have been recognized and a possible third, a deeper target, has been identified by deep penetrating geophysical surveys over the area. Drilling will continue to focus on this area where the geophysical anomaly associated with the mineralization has been traced for more than 1 kilometre. The mineralization seen to date is semi-massive to stringer (remobilized) type sulphides. Variable amounts of pyrrhotite and chalcopyrite occur, with lesser amounts of sphalerite and magnetite.

PREVIOUSLY RELEASED SUPERZONE HIGHLIGHTS

  • Hole RLE004 Intersects 0.34 m of 5.41% Cu, 0.27% Zn, 1.58 g/t Au,
    and 7.57 g/t Ag (May 17, 2011)
  • Hole RLE006 Intersects 7.18 m of 7.44% Cu, 0.23% Zn, 0.48 g/t Au, and 7.57 g/t Ag
    and 44.9 m of 0.79% Cu, 0.39% Zn, 0.16 g/t Au and 1.58 g/t Ag (May 17, 2011)
  • Hole RLE007 Intersects 2.23 m of 5.94% Cu, 0.27% Zn, 0.40 g/t Au and 5.50 g/t Ag
    and 24.70 m of 0.21% Cu, 1.18% Zn, 0.08 g/t Au and 0.79 g/t Ag (August 9, 2011)

VMS UPDATES PROGRESS ON ITS 2011 EXPLORATION PROGRAMS IN THE FLIN FLON – SNOW LAKE GREENSTONE BELT, MANITOBA

VMS Ventures Inc. updates its shareholders on the Company’s ongoing exploration programs on its extensive land package in the Flin Flon – Snow Lake  Greenstone Belt, Manitoba.

Twenty-five (25) diamond drill holes have been completed to date targeting Versatile Time Domain Electromagnetic anomalies (VTEM), surface pulse electromagnetic anomalies and magnetic features on the option and joint venture properties.  Most of the drilling has been focusing on a VTEM anomaly located approximately 2.0 kilometres northeast of the Reed Copper deposit which hosts an indicated resource of 2.6 million tonnes grading 4.52% copper, 0.91% zinc, 0.64 g/t gold, 7.86 g/t silver (NI 43-101, April 2011).  Results from earlier drilling on the target 2 km north of the Reed Copper deposit, have returned 7.18 metres of 7.44% copper (May, 2011) and 2.23 metres of 5.94% copper (August, 2011) on this target.  Drilling was suspended for two weeks in July for holidays and has now returned to full operation.  Assays are pending, and are expected shortly. (see figure 1 – Superzone Area)

HudBay is continuing to drill VTEM anomalies on the option properties and conduct additional Time-Domain Electromagnetic ground surveys (TDEM) and borehole pulse electromagnetic surveys (BHPEM) for follow-up drilling programs.


Copper occurances discovery after TEM airborne survey

Posted by on Tuesday, 2 August, 2011

The second copper occurance at the Cowan Project in Manitoba, near the Reed Project ( http://explorationgeophysics.info/?p=1767 ) , is approximately 2 km from the first discovery there announced earlier in the year (6.59m of 2.25% copper, including 9.81% copper over 1.39 m). The map below shows you the location of the two copper occurances at Cowan and the large grid being constructed to run a deep looking geophysical survey, to be undertaken shortly.

John Roozendaal, President & Director of VMS Ventures Inc.:

“When the VMS deposits of this belt were formed about 2 billion years ago, there was an ancient sea floor with volcanic activity taking place. Scientists can actually see these same physical processes occurring today by way of deep sea submarines traveling to areas of today’s oceans where this activity is taking place now. As a result, geologists have learned a great deal about how these deposits formed, the spatial relationships between deposits and the key features that tell us when we are in a hydro-thermal vent field and thus potentially close to a VMS deposit. The copper mineralization at Cowan occurs as sulphide mineral veinlets in hydrothermally altered rock, which is a key feature for explorationists looking for Volcanogenic Massive Sulphide deposits.

When the hot fluids, laden with metals rise through the ocean crust, through fractures in the rock, they alter the rocks to form the very  minerals which tell geologists that such a system was active in these ancient ocean rocks and also leave behind sulphide minerals as veins. From studies of modern vent fields, and also of mines that have formed in these ancient rocks, we know that these vents don’t generally come up alone, but as part of a greater vent field with multiple vents issuing the hot fluids which provide the metal for these copper-zinc-silver-gold rich deposits.

The Cowan discovery was our first indication of finding another vent field in the Reed Lake area. This new second occurrence, announced this morning, confirms to our geologists that this area is highly prospective and capable of hosting multiple vents over a large area, thus has the potential for one, or many, deposits. The challenge as always is locating the vents that produced the larger and richer deposits worthy of mining.

A deep looking ground geophysical survey, with lines spaced every hundred meters over this 2 km area, is the next step towards finding these deposits. The fact that both occurances have high copper values along with highly anomalous zinc-silver-gold values is very encouraging, as that is what makes Flin Flon – Snow Lake VMS deposits so valuable.”


Completion Of Airborne Geophysical Survey In Northwestern British Columbia

Posted by on Thursday, 23 June, 2011

Romios Gold Resources Inc.  announces the completion of a 743 line-kilometre airborne geophysical survey over the Company’s wholly owned Dirk and Andrei properties in the Galore Creek area, Northwestern British Columbia. The geophysical survey employed Fugro Airborne’s “DIGHEM” system, measuring multiple frequency electromagnetic fields to produce high-resolution electromagnetic resistivity and magnetic anomaly maps of the top 150 metres of the earth’s crust. The DIGHEM system, in development and use for over 40 years, is widely used in the mining and exploration industry and has aided mineral exploration at other properties in the area such as Newmont Lake, Trek, Galore Creek, and Copper Canyon.

Preliminary results of the Fugro survey over the Dirk property suggest a coincidence between a broad, northeasterly striking magnetic anomaly of moderate intensity with a megacrystic syenite porphyry, similar to those found at Galore Creek. Surface mineralization on the Dirk property is reflected as geophysical anomalies exhibiting a high-magnetic, low-resistivity signature within and adjacent to a larger magnetic anomaly outlined in the Fugro Airborne Survey. Together, the broad magnetic anomaly and the anomalies reflecting surface mineralization, cover an area approximately 9.6 km long by 3.0 km wide. A 2010 mapping project from the British Columbia Geological Survey (BCGS) supported Romios’ contention that the Dirk property mineralization is analogous to and may be as large as the Galore Creek Project.

The Dirk and the recently staked Andrei property are described by the BCGS as holding the potential for VMS (volcanic massive sulphide) – related mineralization. Known silver, zinc, and copper- mineralization within rhyolite ash flows on the Andrei property are manifested in the Fugro surveys as geophysical anomalies which exhibit low to moderate resisivity and moderate magnetic signatures similar to those recorded over the National Instrument 43-101 Inferred Resource of the Northwest Zone on the Newmont Lake property.

A more comprehensive analysis of the Dirk and Andrei geophysical surveys will be conducted upon receipt of the completed and final results from Fugro Airborne Surveys. Maps of the preliminary results will be posted on Romios’ website.

The airborne geophysical survey is part of the $6+ million 2011 exploration program which also includes approximately 10,200 metres of diamond drilling on the Trek property, 1,200 metres on the Dirk property, and 400 metres on the Newmont Lake property.

Drilling commenced on June 2, 2011 on the Tangle and North Zones at the Trek Property. The first hole has been completed on the Tangle Zone and has encountered variable amounts of sulphide mineralization. This mineralization correlates well with the IP (induced polarization) and MT (magnetotelluric) anomalies identified in the 2010 Titan 24 Survey. Drilling on the second hole on the Tangle Zone is in progress.

Drilling has also commenced on the first hole of the 2011 season in the North Zone targeting the near surface mineralization and the deeper MT anomaly identified by the 2010 Titan Survey. All drilling results will be announced as soon as they are available.


TEM and IP on Flin Flon – Snow Lake Greenstone Belt properties

Posted by on Monday, 9 May, 2011

VMS Ventures Inc. updates its shareholders on the Company’s ongoing exploration programs on its extensive land package in the Flin Flon – Snow Lake Greenstone Belt, Manitoba.

VMS EXPLORATION PROPERTIES

Tower Zone, Super Zone, Northeast and Northwest

Airborne surveys (VTEM), data compilation and limited soil geochemistry (MMI) over specific targets have been completed on the option properties. Four drill holes have now been completed, testing VTEM and BHPEM anomalies. Hole RLE002 tested BHPEM target from hole RN-10-07, hole RLE003 tested a weak VTEM with magnetic coincidence located 1.1 km west of the Reed Lake deposit, and RLE004 targeted VTEM anomaly VT119 with magnetic coincidence located on the Super Zone option and deepened TZ-09-11 to test BHPEM targets. Assays are pending.

HudBay is continuing to drill VTEM anomalies on the option properties and is conducting additional Time-Domain Electromagnetic ground surveys (TDEM) for follow-up drilling programs.

Reed Lake

The Reed Lake deposit is a base metal, polymetallic, massive sulphide-type deposit and is located approximately 100 kilometres from HudBay’s concentrator in Flin Flon, Manitoba. Geotechnical drilling is on-going and being supervised by Golder Associates, with results expected in the coming months. Hole RLE001 was designed to test the magnetic anomaly just west of the deposit. However, while this hole intersected magnetite, no economic sulphides were present. Diamond drilling is currently on-going with hole RD-08-42 be deepened to approximately 1,200 metres. The drill is testing a broad approach borehole pulse electromagnetic anomaly. A prefeasibility study is proposed with an underground bulk sample for metallurgical work and ore resource reconciliation.

Cowan River

The Cowan River Project is located 45 kilometres southwest of the town of Snow Lake, and 8 kilometres east of our Reed Lake discovery. VMS Ventures announced a copper discovery on April 13, 2011, in hole RE-11-001, grading 9.81% copper over 1.37 metres. To date, a total of 834 metres in three holes have been completed on this new discovery and additional 666 metres in two holes have been completed on additional VTEM targets in the area. Additional drilling on this discovery and other un-tested VTEM anomalies will take place in summer 2011.

Sails Lake

On January 11, 2011, the Company announced a gold discovery at its Sails Lake Project featuring an intercept of 56.89 metres (186.65 feet) grading 1.21 grams/tonne gold. The mineralized zone occurs within 40 metres of the surface. The Sails Lake Project is located 25 km east of the town of Snow Lake.

A follow-up program of line-cutting and Induced Polarization (IP) geophysical surveys is now complete with the final interpretations forthcoming. Diamond drilling is currently being carried out near the discovery and will be followed up with trenching and geological mapping later this summer.

Copper

A total of 2,560 metres were drilled in 7 holes on the Company’s Copper Project located approximately 30 km south of the mining community of Snow Lake, Manitoba. On April 27, 2011, the Company announced a new zinc discovery in hole CP-11-006, grading 1.76% zinc over 2.04 metres and follow-up hole CP-11-012 intersected anomalous zinc, gold and silver. The company is now reviewing data and assessing additional VTEM targets in the vicinity of this discovery. Additional drilling is being planned for summer 2011.

Morton Lake

The Morton Lake Project is located 25 km west of Snow Lake and within 500 metres of the past-producing Dickstone copper-zinc deposit. A deep-penetrating, ground based Time Domain Electromagnetic geophysical survey was completed by Koop Geotechnical Inc. during the first quarter of 2011. The 54 line kilometre survey assessed a long portion of favourable stratigraphy that hosted the nearby Dickstone copper-zinc deposit. Geotech Ltd. completed 340 line kilometres “Versatile Time Domain Electromagnetic” (VTEM – plus) airborne survey over our recently acquired southern claim blocks. A total of 957 metres in 3 holes have been completed to date, assay results pending.

Ruttan and Fox

The Ruttan and Fox Projects are located in the Lynn Lake – Leaf Rapids Greenstone Belt in northern Manitoba. This belt is part of the northern Trans-Hudson orogeny and hosts the past producing Ruttan mine (69.8 MT at 1.28% Cu and 1.40% Zn) and Fox mine (10.8 MT at 1.81% Cu and 1.77% Zn) historical geological resource, non NI 43-101 compliant. The company is currently compiling historical information and integration of a recent VTEM survey to augment our MMI soil survey which is scheduled for Q3. Exploration targeting will commence shortly.


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.


Ground and airborne time-domain for Rocky Lake project

Posted by on Saturday, 30 April, 2011

QMC Quantum Minerals Corp. provides an update and announce that the Company has received permits for drilling on the Rocky Lake, Manitoba, Canada project from the Ministry of Innovation, Energy and Mines. Drilling is scheduled to start in the latter half of June, 2011 and it is intended to source drilling equipment available locally.

The Rocky Lake project is well situated in the mineral prolific region of the province some 50 km North West of The Pas. And, the city of Flin Flon with its smelter, is 65 km to the north with the Namew Lake Ni-Cu mine 1 km North West. The Pas – Flin Flon highway passes 14 km east of the property and the Hudson’s Bay rail line is 15 km to the East. The project is accessible the majority of the year by 4 wheel drive and year-round by all terrain vehicles (ATV). Important infrastructure including human, goods, services and supplies are all readily available.

QMC’s Rocky Lake property is composed of Mineral Exploration License No. 219A (5,000 hectares) and Jaln 1 Claim No. MB 7972 (256 hectares). The adjacent area surrounding 219A and the Jaln 1 are held as the Rocky-Namew Project, composed of Manitoba exploration licenses No. 358A, 359A and the Namew Lake Property is composed of exploration licenses 360A and 361A.

QMC’s drilling program will initially target the strong Pulse Domain Electromagnetic (PEM) conductor anomalies delineated by the 21 line km Crone geophysics survey completed on license no. 219A by QMC.  These PEM anomalies could well represent hidden massive sulphide bodies at depth. Total drilling footage is anticipated to be 5000 meters.

The Rocky Lake Copper prospect was discovered in June of 1987, when airborne geophysical surveys detected a 5 km. long conductor and further ground EM surveys outlined a 1500 meter long conductor associated with a magnetic high. Hudson Bay diamond drilled 10 NQ and BQ holes totaling 2,292 meters in three programs; five in 1987, three in1990 and two in 1991. The ground was subsequently acquired by QMC from 4920776 Manitoba Ltd. as Mineral Exploration License 219A. This Manitoba company, on behalf QMC, cut a new grid over the Hudson Bay anomaly and completed the Crone survey.

The main target on the Rocky Lake VMS property will be the copper occurrence because of the pertinent grades intersected by Hudson Bay Exploration and Development in the late 1980’s and early 1990’s. A total of ten holes were drilled over a length of 1 km., with the best intersection encountering 10.3 meters grading 0.38% Cu (including 4.3 metres @ 0.67% Cu) in RES-122. This intersection contained high-grade sections (up to 3.0% Cu across 0.3m) within the 10.3 m. The Crone PEM survey suggests that some of the strongest portions of the original Hudson Bay electromagnetic anomaly were not adequately tested. The drilling appears to have been carried out on the footwall side of the potential mineralized body, thereby missing the main target. Copper mineralization intersected in the Hudson Bay drilling is present as stringers and could represent footwall stringer mineralization adding credence that the main massive sulphide mineralized body may well have been missed.

In 1980, INCO conducted the initial exploration of Precambrian VMS deposits South of Flin Flon Snow Lake that is covered by Paleozoic sedimentary strata. Following on airborne electromagnetic-magnetic surveys and follow-up ground geophysical surveys, a limited number of diamond drill holes were completed. The Hudson Bay team completed airborne EM-magnetic surveys south of Flin Flon (Menard et al 1996) in the early 1980’s that delineated several conductors. Subsequent drilling led to the discovery of the Namew Lake metamorphosed magmatic Ni-Cu deposit in 1984. The Namew Lake mine was developed by Hudson Bay (60%) and Outukumpu Mines Ltd. (40%) and when the mine closed in 1993, it had produced 2.57 million tonnes grading 0.63% Cu and 1.79% Ni as well as 0.1 g/t Au, 4.1 g/t Ag, 0.5 g/t Pd and 0.6 g/t Pt (Menard et al, 1996).

QMC commissioned airborne Geotech VTEM plus survey to cover Rocky Lake project licenses and claims for a total of 2142 line kilometers. This is a follow-up of the PEM survey. As mentioned above the PEM survey returned strong conductor anomalies. It will be important to note comparisons of any potential Geotech VTEM anomalies to the PEM survey anomalies. This will aid identifying similar potential drilling targets on the other licenses.

Geotech’s VTEM plus Time Domain EM system has been shown to locate discrete conductive anomalies as well as mapping lateral and vertical variations in resistivity. The VTEM plus system is equipped with a high-sensitivity magnetic gradiometer for mapping geologic structure and lithology. Geotech is a leading innovator in the airborne electromagnetics industry through the development of new and progressive airborne geophysical technologies. These conductors could represent hidden volcanogenic massive sulphide mineralized bodies at depth.
