Midland Exploration Inc.  reports the beginning of its exploration activity on its 100% owned James Bay Éléonore Gold project located in James Bay, Québec. The first phase of the 2014 exploration program consists of a helicopter airborne magnetic geophysical survey over the Éléonore Centre property.

The Eléonore project, which encompasses the Éléonore Centre and West properties, is constituted of a total of 247 claims covering 128 square kilometres, and is located approximately 30 kilometres southwest from and in a geological environment similar to Goldcorp Inc.’s Éléonore deposit. This world-class gold deposit contains reserves of 4.03 Moz Au (proven and probable categories), combined measured and indicated resources of 4.84 Moz Au and inferred resources estimated at 4.10 Moz Au. (Source: Goldcorp press release dated February 13, 2014).

Prospecting conducted by Midland from 2009 to 2013 on the Éléonore Centre property identified the presence of several gold showings associated with quartz-tourmaline pyrite bearing veinlets occurring in sheared metasediments, as well as mafic and felsic metavolcanics which returned up to 18.8 g/t Au. These results strongly suggest that an auriferous hydrothermal system is present on the property by a strong abundance of quartz-tourmaline veins over a plurimetric area. In addition, the 2013 ground induced polarisation (“IP”) survey identified many north-south trending IP anomalies and several remain unexplained. The 2011 soil geochemistry survey permitted to delineate a series of As-Cu-Sb anomalies clustered along a north-south-trending axis. Finally, a series of parallel northeast trending AeroTEM II conductors were outlined by the 2010 airborne geophysical survey which targeted sulfide bearing Éléonore-type sediments on the northern part of the Éléonore Centre property. Some of these conductors coincide with uncovered gold-bearing disseminated to semi-massive sulfides zones identified by Midland and several EM anomalies still remain unexplained.

A high definition airborne magnetic survey covering the Éléonore Centre property was just completed, including the area covered by the 2013 IP survey. The results and interpretation of this survey, totalizing 386 linear kilometres, are pending. Furthermore, preparation for the upcoming 2014 summer exploration program on the Éléonore Centre property currently underway.

Location:

  • The Eleonore property is located about 450 kilometres north of the town of Matagami, in the Opinaca Reservoir area, James Bay, Quebec.

Property:

  • The Eleonore property consists of two claim blocks (Centre and West). The Centre Block consists of 121 claims covering a surface area of about 63 square kilometres, whereas the West Block consists of 109 claims covering about 57 square kilometres. The two blocks are located about 30 kilometres southwest of the Roberto deposit on the Eleonore property held by Goldcorp, where measured and indicated resources are estimated at 3.15 million ounces of gold and inferred resources at 6.25 million ounces of gold.

Highlights:

  • Covers a major N-S-trending structure between metasedimentary rocks and metavolcanic rocks interpreted as the extension of the structure occurring near the Eleonore gold deposit.
  • Prospecting work has uncovered many new gold showings associated with metasedimentary rocks (conglomerates and greywackes):
    • Golden Gun showing: 18.8 g/t Au, 13.6 g/t Au, 0.76 g/t Au
    • Golden Gun West showing : 1.69 g/t Au
    • Aston Martin showing : 1.63 g/t Au
    • Gold Finger showing: 1.01 g/t Au, 0.82 g/t Au
    • Golden Eye showing: 1.90 g/t Au, 0.90 g/t Au
    • Casino showing: 0.76 g/t Au, 0.64 g/t Au
  • Located along a regional metamorphic gradient, typical of the contact between the La Grande and Opinaca groups.
  • New soil (humus) geochemistry anomalies identified in the south part of the Eleonore Centre Block.

Geophysical exploration program in Nicaragua

Posted by on Tuesday, 18 February, 2014

Caza Gold Corp. announces that the Company has initiated the 2014 exploration program at the Los Andes and Pochote properties in Nicaragua. The Company is planning a large airborne geophysical survey and a drilling program which will test 2 of the highest priority gold targets.

Plans are underway to complete a geophysical survey along a 12 kilometer long trend of continuous alteration within the Los Andes and Pochote claims, followed by a drilling program to test two gold targets not previously drill tested during the 2012 Pedregal program. The upcoming drilling will test the Quisaltepe and San Francisco gold zones. Access agreements have been obtained for the San Francisco area and drill access road construction is underway. Negotiations for access in the Quisaltepe area are being finalized. The drilling program is expected to begin, pending contractor scheduling, by April and is planned to complete approximately 10 to 15 holes each 200 to 250 meters deep. A dedicated budget of approximately CDN$1.3 million has been set aside from the proceeds of the December 2013 CDN$2.5 million financing to execute the exploration program.

The Company has contracted Aeroquest Airborne to complete the helicopter based geophysical survey which will cover approximately 36 square kilometers over the Pedregal, Quisaltepe and San Francisco gold targets acquiring versatile time domain electromagnetic (VTEM) and magnetic data along approximately 530 line kilometers at 100 meter line spacing. The survey is scheduled to begin in March pending the importation of the survey equipment and final scheduling of personnel and equipment. Geophysical survey results in conjunction with geochemical results, structural and alteration mapping will further define the drilling locations.

The VTEM and magnetic data are targeting the conductive massive sulfide horizons and the resistive silicified zones associated with large faults and possible areas of gold mineralization. The magnetic portion of the survey will provide additional information identifying the fault zones and deeper porphyry style mineralization and intrusive bodies. The survey will cover the Pedregal area, drilled in 2012, which intersected thick horizons of sulfide mineralization and strongly silicified zones with elevated but sub- economic gold concentrations (refer to Nov. 29, 2012 news release for details) and along the 10 kilometer trend to the San Francisco target at the south end of the zone.

Los Andes High Sulfidation Gold Property, Nicaragua

The Los Andes Property is located approximately 1 hour east of Managua on Highway 7 with excellent access. The property covers approximately 6,575 hectares and is strategically located within the Central Nicaragua Gold Belt between the El Limon and La Libertad Mines of B2 Gold.

The Los Andes property is a high-sulfidation style of gold mineralization.  High-sulfidation gold systems host some of the largest gold deposits in the world with examples such as Yanacocha and Pierina in Peru.  Favorable alteration and mineralization has been traced along the regional northeast trending Los Andes structure for at least 11 km on the Los Andes property.  The extensive alteration system is exposed on the surface and consists of very strong silicification associated with zoned alteration from higher temperature advanced argillic zones surrounded by successively lower temperature argillic, and propyllitic alteration.  The alteration is associated with anomalous values of gold, silver, and highly anomalous levels of indicator metals such as bismuth, tellurium, selenium, arsenic, antimony, and mercury.


Planned airborne geophysical survey looking for an economic graphite deposit at Blackflake property

Posted by on Monday, 10 February, 2014

Xmet Inc. announces that it has engaged Aeroquest International to complete a new round of Versatile Time Domain Electromagnetic (“VTEM”) and Magnetic Gradiometer Survey on its newly acquired 20,000 acres of 100% owned claims which expanded Blackflake’s total area to 29,400 acres. The airborne survey will begin in the next few days.

“This will be our third round of EM aerial surveys and with the exploration success Xmet achieved with its first two EM surveys, we are excited about the potential for this next round of VTEM,” said Xmet’s Chairman and CEO Alexander Stewart.

He continued by saying, “Our primary objective remains to drill test our prime anomaly, disclosed in our news release of December 12, 2013, for which permits for ground geophysics and drilling are expected to be received this month. However this newly acquired land and the further upside potential that the VTEM can deliver is equally exciting.”

Embedded in this news release is a MAP depicting Blackflake’s Eastern Claim Block. As per the map’s legend, the yellow portion within Xmet’s claim block denotes Xmet’s land package prior to January 30th, 2014 News Release and the horizontal grid lines within Xmet’s claim block denotes the 20,000 acres of new claims staked along with the area that will be flown in this round of VTEM.

VTEM Max Survey Commenced by TAD on Uranium Prospect in the Athabasca Basin

Posted by on Wednesday, 29 January, 2014

 

 

 

TAD Mineral Exploration Inc.  announces that the initial work program consisting of a VTEM max program over its uranium block in the Patterson Lake Area of the Athabasca Basin, Saskatchewan has commenced. This survey will assist in locating the basement indicators on the property.

James Nelson, a director of TAD stated, “We are pleased to be underway on this project. When you consider the exposure that the Athabasca Basin has garnered, especially in the light of the recent significant new discovery made by Fisson at the Patterson Lake South property, we are excited to be active on a prospect in this uranium district.”

According to Aeroquest, “The VTEM max or Versatile Time Domain Electro Magnetic system is the most innovative and successful airborne electromagnetic system to be introduced in more than 30 years. The proprietary receiver design using the advantages of modern digital electronics and signal processing delivers exceptionally low-noise levels. Coupled with a high dipole moment transmitter, the result is unparalleled resolution and depth of investigation in precision electromagnetic measurements. The system was designed to be field configurable to best suit a large variety of different geophysical requirements from deep penetration to optimizing the discrimination within a narrow range of resistivity values.”

TAD has added three new prospects. One new prospect is located in the world renowned uranium district of the Athabasca Basin in Saskatchewan in close proximity to the Alpha/ Fission Patterson Lake South discovery. Another new prospect is the Iskut copper/gold prospect near Colorado Resource’s ‘North Rok’ discovery in British Columbia. A third new project is a hydrothermal graphite prospect bordering Zenyatta Ventures Ltd.’s recently discovered deposit.


Radon Survey Commences to Prioritize Untested Conductors for uranium in Athabasca basin

Posted by on Monday, 13 January, 2014

FISSION URANIUM CORP. announces it has commenced a new large coverage, $500,000 Radon in lake survey at its 100% owned Patterson Lake South (PLS) property in Canada’s Athabasca Basin. The survey is following up on ten geophysics-identified basement electromagnetic (EM) conductors. Fission’s lake bottom technique survey, conducted in the winter beneath the ice, and analysis has proved key in identifying radioactive anomalies and assisting accurate drill targeting in the previous two drill programs at PLS (>86% mineralization hit rate). To date, Fission’s highly successful Radon survey and analysis has been used systematically on only 1 EM conductor (PL3B conductor) on a property which hosts over 100 such basement EM conductors.

The ten conductors are located in 4 separate areas (Area A, B, C and D) beneath Patterson Lake and Forest Lake.

Ross McElroy, President, COO, and Chief Geologist for Fission, commented,

Our lake bottom, winter radon survey and analysis techniques were critical elements in targeting the first strike holes at six of the seven zones and numerous successful step-outs. PLS is a hugely prospective property with a multitude of conductors and just as our understanding of the geology has evolved in the past two exploration programs, so too has our use of Radon survey technology. With approximately 20% of the upcoming drilling focusing on exploring new areas of interest, we expect this radon survey to play an important role in targeting and prioritizing new holes.”

News Highlights

  • 10X expansion of radon survey coverage at PLS
  • Areas to be targeted include a total of ten high priority EM conductors
  • Survey has already commenced and is expected to take five to six weeks to complete
  • Fission’s use of radon has been instrumental in targeting the first holes at six zones found to date and successfully hitting step outs as large as 390m
  • A total of 2,300 samples will be taken from 4 areas covering discrete identified EM conductors. Areas A, B and C cover EM conductors within Patterson Lake. Area B covers EM conductors within Forrest Lake, located immediately to the south of Patterson Lake – all areas are on the PLS property
  • Forest Lake Radon Survey Area

An EIC (Electret Ionization Chamber) survey to measure radon, will be conducted by RadonEx Exploration Management, of St Lazare, Quebec. The survey will comprise primarily samples of measurements of radon in water.

Area A

Area A is comprised of a group of 4 main north-east trending EM conductors, including the PL3B EM conductor (which is associated with the high-grade “R” zones). The upcoming survey will cover 3 parallel interpreted time domain electromagnetic (TDEM) conductors, each discrete conductor ranging in strike length between 1.0km – 1.9km strike length. A total of 743 samples will be collected.

Area B

Area B is located approximately 2 to 3km north-east of the PL-3B conductors. The survey will cover a single 1.2km long north-east trending EM conductor. A total of 231 samples will be collected.

Area C

Area C encompasses two discontinuous north-east oriented and segmented airborne EM conductors (VTEM). The northern conductor is interpreted to be segmented in 2 sections, of strike length of 1.2km and 0.3km respectively. The southern conductor is similarly segmented in 2 sections of 0.7km and 0.3km each. A total of 305 samples will be collected.

Area D

Area D encompasses three intermittent north-east trending VTEM conductors. Two conductors cover a strike length of 4.1km, while the 3rdcovers a length of 1.3km. A total of 1,031 samples will be collected.

Patterson Lake South Property

The 31,039 hectare PLS project is 100% owned and operated by Fission Uranium Corp. PLS is accessible by road with primary access from all-weather Highway 955, which runs north to the former Cluff Lake mine and passes through the nearby UEX-Areva Shea Creek discoveries located 50km to the north, currently under active exploration and development.

 


Linking Porphyry Deposit Geology to Geophysics via Physical Properties

Posted by on Tuesday, 7 January, 2014

Geoscience BC Releases the Report:

Linking Porphyry Deposit Geology to Geophysics via Physical Properties: Adding Value to Geoscience BC Geophysical Data
by Dianne Mitchinson, MDRU; R.J. Enkin, GSC; and C.J.R. Hart, MDRU.

Regional geophysical surveys were flown in 2007 and 2008 as part of the QUEST and QUEST-West projects to improve geological understanding in Quaternary sediment-covered areas and thereby encourage mineral exploration. As part of the ongoing process of adding value to Geoscience BC datasets, Project 2009-001, “Integrated Geological & Geophysical Porphyry Models: Adding Value to Geoscience BC Geophysical Data (NTS 93E, 93K, 93L, 93M, 93N)” was undertaken to define relationships between geophysical datasets collected as part of these QUEST surveys and porphyry deposit geology at six known porphyry deposits. The deposits chosen for investigation include: Mount Milligan, Endako, Huckleberry, Bell, Granisle and Morrison. 
Geoscience BC Report 2013-14 presents physical rock property data from the six above-listed BC porphyry deposits, and discusses observed trends within the detailed QUEST and QUEST-West geophysical datasets and mapped geology. The resulting physical rock property data compilation has implications for improving interpretations of geophysical data from porphyry deposits. A synopsis of physical property criteria defining hydrothermally altered or mineralized rocks in BC porphyry settings is provided, which can ultimately be used for ranking similar mineral exploration targets throughout BC, thereby minimizing exploration risk.

Airborne Geophysical Survey Along Trend Of The Alpha/Fission Patterson Lake Discovery

Posted by on Tuesday, 28 May, 2013

Forum Uranium Corp. announces the commencement of an electromagnetic and magnetic survey of its 100% owned Clearwater Project. Forum’s claims, staked immediately adjacent to the southwest of the Alpha Minerals/Fission Uranium claim boundary is interpreted to be on strike with the fertile conductive trend that hosts the high-grade uranium discovery on the Patterson Lake South project. Forum’s property lies only four kilometres southwest of the high grade boulder train on the Alpha/Fission property.

Figure shows historical electromagnetic trends, a magnetic map and lake sediment geochemical surveys in the Patterson Lake South area. The electromagnetic (EM) surveys stopped at Forum’s claim boundary, however EM conductors from these historic surveys trend in the direction of Forum’s ground. Of particular note is that the highest lake sediment value in the area lies on Forum’s southwest claim with a value of 8.3 ppm U. Most values are between 1 to 3 ppm U and the lake sediment sample taken down-ice from the Patterson lake boulder field was 3.2 ppm U.

An Aeroquest Airborne helicopter-borne time domain electromagnetic survey with Bfield-VTEM Plus and magnetic gradiometer system will be flown on 200 metre line spacings for a total of 647 line kilometres over Forum’s 99 square kilometre property. The VTEM Plus system has been chosen for its depth penetration and vertical/spatial resolution of graphitic conductors that are prospective hosts for unconformity-style uranium deposits.

This is the first phase of this year’s summer exploration program. Plans are to conduct an airborne radiometric survey and a detailed prospecting survey to search for any boulder fields similar to that found on the Alpha/Fission ground.


Airborne EM Survey over the Blu Starr Flake Graphite Property in BC

Posted by on Monday, 22 October, 2012

Anglo Swiss Resources Inc. has announced plans to commence an airborne electromagnetic (EM) survey over its Blu Starr Flake Graphite Property located near Nelson in southeastern BC. The property adjoins Eagle Graphite Corporation’s flake graphite operation which is one of only two natural flake graphite mines in North America. Next to Eagle Graphite, Anglo Swiss holds the largest land package covering 6,473 hectare (~65 sq. km) in the southern part of the favourable Valhalla Metamorphic Complex (see attached maps).

The planned ~550 line-kilometre survey will complete EM geophysical coverage over the entire property expanding on the 2010 survey completed by the Company. The earlier survey outlined a three kilometre long, shallow south-dipping conductor on the north side of Perry Peak which correlates well with numerous outcrops of large flake graphite occurrences known as the Tedesco showing. At this time the total thickness of the graphite bearing units is unknown as this conductor has not been drill tested. The new EM survey will cover the southern half of Perry Peak and central part of the property with the goal of identifying the possible southern extension of Tedesco as well as new large EM conductors. Aeroquest Airborne Limited will be conducting the EM survey utilizing the AeroTEM IV system.

Geology – Property

The varied geology of the property has been extensively mapped. Metamorphic rocks of the Valhalla Complex in the Passmore Dome area belong to the “upper sheet,” lying between the Airy quartz monzonite sheet dated at 62 Ma and the underlying Mulvey granodioritic gneiss sheet dated at 100 Ma. Graphite and minor sulphidebearing carbonate and calc-silicate layers lie at a structurally higher level in the the upper sheet, than that of the cordierite (iolite) and corundum (sapphire) bearing lenses that appear to lie within or near to the Gwillim Creek shear zone.

The Tedesco area geological map units cannot be directly correlated with other areas of the Slocan property. The Tedesco area hosts distinctive graphitic marble layers not known to occur on other areas of the property. During mapping and surveying, five distinct rock unites were observed.

Research –  Geophysical Survey

IP surveys of this property have identified a pronounced anomalous chargeability, possibly attributed to flat-lying marble or calc-silicate horizons containing concentrations of conductive graphite, possibly with other associated sulphide minerals such as pyrrhotite and pyrite.

The total magnetic field survey produced dissimilar but conspicuous magnetic features that might be attributed to either magnetite or pyrrhotite in the host rock.


Butler Project – Exploration Overview with Geophysics

Posted by on Tuesday, 14 February, 2012

MacDonald Mines Exploration Ltd. provides an exploration update in the mineral-rich Ring of Fire region of the James Bay Lowlands.

MacDonald began exploring in the Ring of Fire starting in 2003, shortly after the first volcanogenic massive sulphide (VMS) discovery at McFaulds Lake by Spider Resources and KWG Resources. The McFaulds VMS discovery is characterized by very high-grade intersections of VMS mineralization (McF-04-57 intersected 18.8 meters of 8.02% Copper (Cu), Mc-03-18 averaged 4.83% Zinc (Zn) over 25.75 meters) and at 250 meter-plus depths.

Exploration in the James Bay Lowlands is challenging due to the area being almost entirely a wetland. As a result, there is minimal outcrop, helicopter support is required and exploration time lines are longer. Over $18 million dollars has been spent to date on the Butler property and we have discovered six zones of multi-element mineralization with copper-zinc VMS systems, vandiferous titano-magnetite and magmatic nickel sulphide. This was accomplished through comprehensive exploration programs including geophysics, diamond drill holes and geochemistry.

Magnetic map (TF) of the Butler Property showing the location of identified multi-element, mineralized zones.

The lack of outcrop requires that a significant amount of attention and detail has to be paid to the geophysical techniques used in the area. Historically the programs focused on shallow targets; however down-hole surveys, ground magnetic and gravity surveys have indicated that the potential deposit(s) of interest lies deeper in the structural sequence.

A comprehensive suite of geophysical tools has applied at Butler:

Airborne EM, Magnetics & Gravity

  • 2004 VTEM – 2138.9 line kilometers of data were collected
  • 2008 VTEM – 1325.6 line kilometers of data were collected
  • 2010 AeroTEM IV – 261 line kilometers of data were collected
  • 2011 HeliGeoTEM – 261 line kilometers of data were collected
  • OGS/GSC Airborne Gravity Gradiometer

Surface EM

  • Butler 1 – 13 line kilometers of data were collected
  • Butler 3 – 39.3 line kilometers of data were collected
  • Butler 5 – 12.5 line kilometers of data were collected
  • Butler 3, 5, 6, and 7 – 30.17 line kilometers of data were collected

Surface Magnetics

  • 7 Ground Magnetic surveys completed in 2011 covering 81.1 line kilometers

Down hole EM

  • 64 diamond drill holes probed and modeled

The Company is currently enhancing the geophysical model to include the geochemistry data results. Collectively, all of the above geophysical results have consistently shown that an electrically conductive unit with magnetic properties and high density lies below those prospective zones.  These are the characteristics expected from a sulphide rich zone.

MacDonald’s upcoming drill program will focus on the Butler property: Prior to drilling, the targets will first be refined using a deep penetrating geophysical method, similar to that used to detect the HudBay – Lalor deposit at Snow Lake, Manitoba.


Radiometric and magnetic survey for REE

Posted by on Saturday, 15 October, 2011

Arctic Star Exploration Corp. announces that Aeroquest International Ltd. has completed airborne magnetic and radiometric surveys on three properties located in the Carbo area of ‘The Rocky Mountain Rare Metal Belt’ of northern British Columbia.

The Cap, Seebach and Javorsky rare earth element (“REE”) and rare metal properties are all located within the immediate vicinity of Spectrum Mining Corporation’s Wicheeda REE Discovery as well as the Carbo Project which has been drilled by Canadian International Minerals Inc. Arctic Star is conducting exploration under its option to earn up to 100% interest in these properties. The group of claims are located 80 km northeast of Prince George and together comprises 20 mineral claims covering approximately 9,129 hectares, making it one of the largest land positions in the camp.

The heli-borne AeroMAG magnetic gradient and radiometric survey consisted of approximately 1,500 line kilometres on the three properties. The preliminary results of the survey have identified several radiometric anomalies on the Cap property, which are considered to be high priority with respect to the other surveyed properties in the Carbo area. The magnetic component of the survey further defined the strong magnetic anomaly as previously defined by the regional magnetic survey.

The preliminary results of the airborne survey, in combination with the 2010 prospecting program which located outcrops of syenite with anomalous values of Nb and Zr (see November 17th News Release) are very encouraging. In the Carbo area, syenite is often found in close proximity to REE bearing carbonatite.

A detailed mapping and prospecting program, in combination with soil sampling has commenced on the Cap Property in order to verify the geophysical anomalies and define drill targets.

Publicly available records show that the nearby Wicheeda REE Discovery owned by Spectrum Mining showed encouraging results for REE in 2008 and 2009 drilling.

Airborne surveys for uranium in Athabasca Basin

Posted by on Tuesday, 27 September, 2011

Unity Energy Corp.  announces that it has acquired through staking a prospective uranium exploration property known as the Milliken Lake Property. The 1,941 hectare claim lies on the eastern edge of the Athabasca Basin, adjoining to the southeast, UEX’s Hidden Bay and to the west Hathor’s Milliken Creek Project. The project area has seen significant exploration activity, including an Aeroquest AeroTEM III time domain helicopter electromagnetic survey in 2005 (UEX) and boulder prospecting survey (Denison) in 2006. With this acquisition, Unity now controls eight quality uranium exploration projects (27,500 hectares) in the most productive region in the world.

Aeroquest’s Mag/EM survey was successful at detecting a northeast trending moderately conductive anomaly, spanning ~4.5km of the Milliken Lake Project. The Milliken Conductor, which appears to be a subtle anomaly that may represent an alteration zone corresponding with a magnetic low, is the Company’s primary exploration target at Milliken Lake. In 1997, Cameco tested a gravity anomaly in the northern portion of the Project, which was then part of the Park Creek Project. The unconformity was intersected at 97.4m (hole GL-1) and 87.95m (hole GL-2). Neither hole intersected alteration or mineralization; the holes were approximately one kilometer north of the Milliken Conductor.

The Company also covered the Milliken Lake Project in its 2011 VTEM survey; an interpretation on the results should be available in the near term.

Unity Energy Corp. has completed a heliborne VTEM geophysical survey over its Close Lake, Lampin Lake, Hoppy Lake, Kirkpatrick Lake and Dickens Lake projects in the northeastern Athabasca basin and La Ronge gold belt. The survey consisted of about 3,385 line kilometres with 100-metre spacing. Unity is awaiting preliminary interpretation and will use the data to refine target zones.

VTEM is highly effective at locating discrete conductive anomalies, magnetic features extending to the basement. It is also highly effective at mapping lateral and vertical variations in resistivity and is a leading-edge solution for uranium exploration in the basin. VTEM is an evolving technology and this latest generation boasts a higher sensitivity achieved by noise reduction and the optimization of transmitter current waveform, along with dipole-moment increases. The low noise level significantly extends conductance aperture and conductance discrimination.

The Athabasca Basin is an ancient sedimentary basin which hosts the World’s most significant uranium mines and produces almost 30% per cent of the current world uranium production of 108 million pounds U3O8. Athabasca uranium deposits also have grades substantially higher than the world average grade of about 0.2% U3O8. The two dozen or so known uranium deposits within the Athabasca Basin have average grades of more than 3.0% U3O8. The two largest deposits, Cigar Lake and McArthur River have average grades of 20% and 24% U3O8 respectively. The near surface uranium mines in the Cluff Lake mine area produced more than 60 million pounds of uranium with gold as a by-product.

The Athabasca Basin is host to unconformity-associated type Uranium deposits. Mineralization occurs at, above or below the unconformity which separates the Proterozoic Athabasca Sandstone Group from the underlying metamorphosed gneissic rock. Uranium mineralization within the Athabasca Basin is primarily hosted by meta-sediments including pelites and calc-silicates and by sandstone of the Athabasca formation. The pelites are commonly graphitic (free carbon) which may have acted as a chemical reductant, fixing uranium from water circulated by large hydrothermal systems. Some Athabasca uranium deposits are associated with faults and these faults may cause displacements of the basal unconformity.


AIRBORNE SURVEYS OVER BC RARE EARTH PROSPECTS

Posted by on Friday, 9 September, 2011

MONTORO RETAINS AEROQUEST FOR AIRBORNE SURVEYS OVER BC RARE EARTH PROSPECTS

International Montoro Resources Inc. has retained Aeroquest International Limited to conduct multiple large scale geophysical and radiometric airborne surveys over the highly prospective “Tacheeda NW” and “Chuchinka NW” Rare Earth Element prospects located in ‘The Rocky Mountain Rare Metal Belt’of northern British Columbia. Both of Montoro’s newly acquired properties are on trend with properties held by Spectrum Mining Corp. (the “Wicheeda” discovery), who announced a 48.64 metre interval which averaged 3.55% REE, a 72.0 metre interval that averaged 2.92% REE, and a 144 metre interval which averaged 2.20% REE in three separate drill holes.

These airborne surveys will assist in identifying and prioritizing Rare Earth Element drill targets for multiple planned upcoming drill programs. The surveys will consist of approx. 1400 line kilometres and will be flown at 50 metre line spacing. The AeroMAG (Gradient & Radiometrics) system is ideal for its superior ability to contour in northern BC’s rugged terrain.

Montoro’s President and CEO, Gary Musil, stated “Several significant anomalies have been discovered on our Chuchinka REE property, using airborne geophysical surveys. Our upcoming 2011 surveys will encompass the newly acquired Tacheeda NW and Chuchinka NW claims. The previous airborne surveys conducted in the area by numerous other companies (ie. Bolero Resources Corp., Canadian International Minerals Inc., Commerce Resources Corp., and Electric Metals Inc.) have all discovered numerous anomalies that have encouraged further advancing those projects into successful sampling and drilling programs, as well as additional discoveries of REE zones”.

Phase 2 exploration at the “Chuchinka” REE property is now underway and will be focused on defining priority drill targets within several anomalies discovered by joint venture partner, Electric Metals Inc. (EMI – TSX.V) through an airborne geophysical survey in 2010. The largest of these targets, measuring over 4 km by 1 km, is located near the centre of the property and is defined by a broad magnetic low associated with coincident conductive anomalies. Geochemical sampling of soils and bedrock, together with ground-based geophysics in the form of precision magnetometer and scintillometer surveying, are being applied to identify the most prospective portions of this and other REE targets in preparation for drilling.


EXPLORATION AT CHUCHINKA REE-CARBONATITE PROPERTY

Posted by on Sunday, 26 June, 2011

ELECTRIC METALS INC. and Montoro Resources Inc announce it has commenced exploration on the Chuchinka REE-Carbonatite property, located in the Wicheeda-Carbo district north of Prince George, British Columbia.

Phase 1 exploration has commenced to define drill targets within several anomalies discovered by Electric Metals with an airborne geophysical survey in 2010 (Aeroquest). The largest of these targets, measuring over 4 km by 1 km, is located near the centre of the property and is defined by a broad magnetic low associated with coincident conductive anomalies. Geochemical sampling of soils and bedrock, together with ground-based geophysics in the form of precision magnetometer and scintillometer surveying, are being applied to identify the most prospective portions of this and other targets.

Phase 2 exploration consisting of trenching and drilling will follow upon receipt of results of the Phase 1 program.


Large geophysical Survey Project in Afghanistan

Posted by on Monday, 9 May, 2011

Aeroquest International Limited reports that it has been selected by the U.S. Geological Survey to undertake a large airborne geophysical survey in Afghanistan. The work will be done at the request of the Task Force for Business and Stability Operation (TFBSO), U.S. Department of Defense, in connection with the TFSBO 2010 mineral resource assessment for Afghanistan1. Aeroquest and the U.S. Geological Survey will immediately commence negotiation of a definitive contract for provision of the survey. While the parties expect that negotiations will conclude satisfactorily within approximately three weeks, no assurance can be given that the result will be a definitive contract.

The contract under final negotiation is expected to call for Aeroquest to provide a minimum of US$3.0 million and up to US$10.0 million of airborne geophysical services in Afghanistan. Aeroquest expects to mobilize two of its proprietary AeroTEM™ systems to Kabul, Afghanistan, and to start collecting data as soon as possible after execution of the definitive contract. Aeroquest expects to spend approximately 60 days in-country; total revenue under the contract will depend somewhat on whether Aeroquest is able to complete all of the survey in the allotted period. Aeroquest expects to record substantially all of the revenue from this project in fiscal 2011.

The planned survey areas comprise up to six blocks totalling just less than 3,500 square kilometers. Over the course of the surveys, Aeroquest expects to operate out of several bases within Afghanistan. In addition to the work to be completed by Aeroquest personnel, some security and survey support will be provided by the United States Government, organized by the TFSBO.

As surveys will be flown in a zone of active conflict, the Company will be incurring additional costs for security and related support to protect its employees and assets. All precautions recommended by TFSBO, the U.S. Geological Survey and supporting contractors will be taken to ensure that Aeroquest employees remain safe and well-protected during the work.

“We are privileged to have an opportunity to take part in the rebuilding of Afghanistan,” said Roy Graydon, President and CEO, of Aeroquest. “Afghanistan has some of the world’s largest unexploited world-class deposits of gold, copper, iron ore and other minerals, estimated by the U.S. Geological Survey to have a value in excess of US$1 trillion.”


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.


Universal HTEM module from Aarhus

Posted by on Wednesday, 3 November, 2010

Aarhus Geophysics announces the release of a general HTEM module that allows complete advanced processing and inversion of virtually every helicopter TEM system on the market today, e.g., VTEM, AeroTEM, HeliTEM. You can now enjoy the full capability of the Aarhus Workbench software for detailed data editing, inversion to smooth and blocky models, results evaluation and display, production of final pdf maps. In true Aarhus Geophysics Aps style, the aim is to go beyond bump anomaly finding, fast approximate transforms or inversions, or any other forms of qualitative appraisal of the AEM data, and to produce quantitative results instead. The aim is to take you … from Data to Knowledge Import your AEM data in the GIS environment of the Aarhus Workbench, describing th e full System Transfer Function, and perform:

-advanced processing of navigation, altimeters and tilt metres data

-decoupling, filtering, and noise assessment of the EM data

-full non linear quasi-3D spatially constrained inversion

-constrained inversion with prior information from boreholes or other geophysics-derived layer boundary

-results evaluation, in terms of Data Residual, Model Parameter Sensitivity, Depth of Investigation

-model display, as horizontal maps in depth and/or elevation, and cross sections

-custom searches of model space and thematic maps, e.g., depth to good conductor.


HIGH GRADE INFILL DRILLING RESULTS AT EAGLE’S NEST

Posted by on Thursday, 14 October, 2010

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

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