The new Key Lake SW Airborne Survey Results

Posted by AP on Tuesday, 17 August, 2010

Kirrin Resources Inc. today announced the results of the evaluation and interpretation of the 1,076 line-km magnetic-electromagnetic (Tempest(R) EM) airborne survey of the Key Lake Southwest (‘Key Lake SW’) uranium property located on the southeastern margin of the Athabasca Basin in Saskatchewan. The Condor Consulting Inc. report identified 7 first priority, 5 second priority and 7 third priority targets that warrant follow-up assessment. Some of these anomalies correlate with geological, geophysical or geochemical anomalies identified from prior exploration, whereas others are newly identified. All are prospective for ingress style (i.e., basement hosted) uranium deposits along the geologically favourable Wollaston Group basement trend.

Commenting on the results, Kirrin President and CEO, Derek J Moran said: “These results have added substantial value to the Key Lake SW uranium project, and show clearly its potential for another eastern Athabasca uranium discovery.”

Processing, interpretation and correlation of the results with magnetic response and geology define two main types of conductors, discrete plate-type and broader, flat lying wide zones (Note 1). These have been further grouped by Condor into 19 target zones and subjectively ranked, according to their conductivity, magnetic association, strike extent and geological association, from high to low priority, with 7 target zones being ranked first priority. Historic wide-spaced drilling on parts of four of the 19 target zones identified prospective geology, including a possible sub-Athabasca Group regolith that was logged in several holes which are located within a Wide Zone EM conductor.

The number one priority target zone has good potential for uranium mineralization because significant uranium values within wide zones of graphitic pelites have been intersected in drill holes targeted along the northeastern extension of this conductor lying within Triex’s Riverlake and Forum Uranium’s Orchid properties. There are 9 other target zones (for a strike length of 52.9 km) which display similar geological and geophysical conductive and magnetic characteristics as observed on adjoining properties and over other uranium deposits in the region and thus are ranked as having high potential for uranium mineralization. The survey also showed that some target zones at Key Lake SW have potential for base metal mineralization or iron formation similar to the geological horizons mapped in the McArthur River mine.

Kirrin is planning the next stage of exploration at Key Lake SW. Follow-up fieldwork at selected first priority targets is likely to comprise (a) systematic prospecting of anomalous conductive trends to prioritise drill targets along those trends, (b) follow-up geochemical lake sediment and possibly soil surveys, (c) magnetic and electro-magnetic surveys on grid areas established over first priority target zones in order to locate conductive axes and attitudes for drill collar positioning, and (d) drill testing of selected targets.

Note1: Magnetic surveys, structural geology, drill and surface geochemistry compiled over the eastern portion of the Athabasca Basin indicate that uranium enrichment and deposits are associated with conductive horizons, located within or along magnetic low troughs, which typically represent graphitic and sometimes magnetite rich iron formations and associated contacts. These horizons are flanked or sandwiched between magnetic highs, which represent underlying Archean type granitoid domes or arches. The reduced magnetism is caused by regional faults, which provide control and form traps for uranium enrichment. The graphitic rich pelite horizons in the basement rock are excellent conductors and host uranium mineralization. They act as markers as they can be located with electromagnetic surveys and targeted with drill holes.


PEREGRINE’s new discovery

Posted by AP on Sunday, 8 August, 2010

Peregrine Diamonds Ltd. reports the discovery of two new kimberlites, named Q1 and Q2, by prospecting on the Company’s 854,000 hectare Qilaq project (“Qilaq” or “the Project”) on Baffin Island, Nunavut, Canada. Qilaq is located on Hall Peninsula, northeast of Iqaluit, the capital of Nunavut, and is adjacent to Peregrine’s Chidliak project (“Chidliak”) where, as reported in a news release on August 4, 2010, the Company has discovered 32 kimberlites in the past two years.

In the spring of this year, Peregrine conducted a 670 line-kilometre helicopter airborne geophysical survey on what represents less than 2% of Qilaq’s area. The 12 geophysical anomalies that were found from this limited survey were prospected and will be prioritized for ground geophysics to be followed by drilling next year. A larger airborne geophysical survey is also being planned for next spring.

Mr. Eric Friedland, Peregrine’s CEO stated “The recent discovery of two kimberlites at surface at Qilaq by prospecting shows that the kimberlite district we have discovered on south Baffin Island continues to expand substantially in area and that this region has excellent potential to host another Canadian diamond mine. Our targeting and exploration methods are producing new kimberlite discoveries at a very rapid pace in Nunavut, and we look forward to more discoveries at Qilaq in the near future. The fact that Qilaq is wholly-owned by Peregrine is especially exciting for our shareholders as it allows us to benefit fully from the value that could result from the potential development of the Project.”

Q1 KIMBERLITE

The spring 2010 helicopter-borne magnetic/electromagnetic geophysical survey revealed a magnetic high anomaly with an estimated diameter of 150 metres associated with a topographic depression that measures approximately 60 metres by 50 metres. Subsequent prospecting led to the discovery of the Q1 kimberlite, represented by large concentrations of coarse-grained KIMs, and kimberlite cobbles and boulders on the surface. Both magmatic kimberlite and probable weathered kimberlite breccia boulders were identified. Pyrope garnet, picroilmenite and chrome diopside grains over 10 millimetres in size were observed on the surface. Clasts of limestone, shale and sandstone, interpreted to have weathered from the kimberlite, are also present on the surface.

Q2 KIMBERLITE

The Q2 kimberlite is located approximately four kilometres south of the Q1 kimberlite and outside of the 2010 airborne geophysical survey. Q2 was discovered through the identification of kimberlite boulders by a field crew that was collecting a follow-up till sample. Subsequent prospecting led to the discovery of two kimberlite outcrops within a surface depression that is more than 80 metres in diameter. At least two phases of kimberlite were identified. One phase is described as being magmatic without limestone xenoliths and the other phase has coarser grained olivine and KIMs and contains limestone xenoliths. Both phases contain olivine, picroilmenite, pyrope garnet and chrome diopside macrocrysts.

Samples from the Q1 and Q2 kimberlites are being sent to the Saskatchewan Research Council for diamond analysis by caustic fusion and results will be reported as they become available. If the diamond results are positive, Q1 and Q2 will be scheduled for drilling as early as possible next year. An exploration summary showing the two new kimberlite discoveries is available athttp://www.pdiam.com/i/pdf/qilaq632.pdf.

QILAQ EXPLORATION UPDATE

Over 300 follow-up sediment samples, related to the seven KIM anomalies identified in 2009, are currently being collected in addition to the prospecting of anomalies revealed from the 2010 airborne geophysical survey in anticipation of a drilling program that is being planned for the next field season. Follow-up geochemical and rock sampling, prospecting and mapping related to precious metals anomalies identified in 2009 is also underway this field season.


Exploration Update on Key Lake SW Uranium Project in the Athabasca

Posted by AP on Tuesday, 6 July, 2010

Kirrin Resources Inc. today announced the completion of a 1,076 line-kilometre magnetic-electromagnetic (EM) airborne survey of the Key Lake Southwest (‘Key Lake SW’) uranium property located on the southeastern margin of the Athabasca Basin in Saskatchewan, Canada. Fugro Airborne Surveys Corp. of Ottawa, Ontario (‘Fugro’) was contracted to complete the survey. In addition, a review of the technical disclosures following the January 10, 2010 announcements by Delta Uranium Inc. (‘Delta’) and Denison Mines Corp. (‘Denison’) of the expansion of their Phoenix Discovery, just 60 km from Key Lake SW, has revealed many geological similarities between Phoenix and Key Lake SW.

Kirrin’s airborne magnetic-EM survey at Key Lake SW utilised Fugro’s fixed-wing Tempest(R) Digital Time Domain Electromagnetic (DTDEM) system which provides maximum quantitative discrimination of relatively near surface (upper 200 to 300 m) conductivity variations. Kirrin has appointed Condor Consulting, Inc. of Lakewood, Colorado,  to undertake the processing and analysis of the airborne EM and magnetic data acquired by Kirrin. Condor anticipates submitting its report by July.

On January 10, 2010, Delta and Denison reported that high-grade uranium mineralization continues to be encountered on the Phoenix discovery on the Wheeler River Property located in the Athabasca Basin of northern Saskatchewan, and that the results of the fall 2009 drilling program have confirmed that the Phoenix discovery has the potential to host an economically significant, high-grade uranium deposit.

The Key Lake SW property is at the southwest end of the geologically favourable trend that hosts numerous uranium mines and important deposits, including the Phoenix and Millennium deposits, and the former Key Lake mine. Although the Key Lake SW property is believed to be somewhat southwest of the margin of the current Athabasca Basin, there is evidence (regolith encountered in some old drill holes) that indicates the Athabasca Supergroup-Wollaston Group basement unconformity was not far above the present ground surface within the property. Discovery of several ‘Ingress style’ uranium deposits, such as Phoenix (up to 117 m below unconformity), Millennium (up to 100 m below unconformity), Eagle Point (up to 450 m below the unconformity) and some other deposits within the Athabasca Basin, indicate that important uranium deposits can occur from several tens of metres up to a few hundred metres below the unconformity. Hence, there is potential for important basement-hosted uranium deposits to exist within the Key Lake SW property. Regional aeromagnetic data show the Phoenix discovery is associated with a fault which cross-cuts the P2 Rift Fault.

Important features at the Phoenix basement-hosted uranium discovery which are similar to the geological setting at the Key Lake SW property include the geological composition of the host basement rocks, the spatial association with the projected regional P2 fault, and the localization of the Phoenix uranium prospect on cross-cutting faults. Gracie (2009) has postulated that the Key Lake SW property is along the projected extension of both the P2 fault, which extends southerly from the McArthur River mine, and the Key Lake fault, which extends southwesterly from the former Key Lake mine.

The eastern margin of the Athabasca Basin is home to the most productive uranium mines in the world with roughly 25% of the world’s uranium production coming from this area. Kirrin’s target at Key Lake SW is basement-hosted unconformity-type uranium deposits, similar to Cameco’s basement-hosted Millennium deposit, located about 50 km to the northeast; the Phoenix discovery, located about 60 km northeast; and the former Key Lake mine, located about 35 km east-northeast.


2010 Frontier Exploration with airborne geophysics

Posted by AP on Monday, 5 July, 2010

Royal Roads Corp.

The 2010 Long Range exploration program is focussed on two areas of activity, the first being the more advanced exploration on the Portage nickel discovery and the second being frontier airborne geophysics and follow-up prospecting over the newly acquired claims recently incorporated into the Long Range property. As of June 17th, 2010, the frontier airborne geophysical surveys over the newly acquired claims was completed with results anticipated to be available in August 2010.  Once received, data will be reviewed to select targets for immediate follow-up by ground prospecting. Areas surveyed by the 1,400 line kilometre Fugro HELITEM® airborne surveys include several properties underlain by unexplored gabbro bodies recently recognized to be prospective for magmatic nickel-copper sulphide deposits. Depending on results, it is hoped that the prospecting activities will help evaluate targets for further work including testing by diamond drilling.

The Long Range property, located 64 kilometres to the southwest of Buchans, covers 381,500 hectares (381.5 km2). The exploration philosophy at Long Range is centered around the potential for discovery of a magmatic nickel sulphide deposit broadly analogous to Vale Inco’s Voisey’s Bay mine in Labrador and Kennecott’s Eagle deposit currently being developed in northern Michigan

An airborne geophysical survey flown over the initial property in 2008 detected a number of anomalies in prospective gabbro. Follow up work ultimately resulted in the discovery of the Portage Nickel prospect and the Range Copper prospect highlighted below. Additional frontier exploration is ongoing to identify new prospects in this highly prospective and un-explored region of Newfoundland.


Norwegian Continental Shelf is under the survey

Posted by AP on Monday, 14 June, 2010

TGS announced another season of acquisition of long offset data on the Norwegian Continental Shelf (NCS) in cooperation with Fugro.  The data to be collected (shown on the attached map) include approximately 15,000 km for the North Sea Renaissance (NSR) survey in Holland, Norway and UK, approximately 10,000 km for the Mid-Norway Regional (MNR) survey in the Norwegian Sea and approximately 15,000 km for the Norwegian Barents Sea Regional (NBR) survey in the Barents Sea.

TGS will dedicate two vessels, Bergen Surveyor and Northern Genesis, during the summer season to acquire the NSR project.  The data acquired by these vessels will be processed at TGS’ imaging center in Bedford, England.  Fugro will also contribute two vessels, Geo Arctic and Akademik Lazarev, to acquire the MNR and NBR data, respectively.  Fugro will process the data acquired on those two projects.

With the 2010 acquisition program, TGS’ total long offset grid on the Norwegian Continental Shelf (NCS) increases to approximately 260,000 km, constituting the most important 2D seismic dataset for the oil industry in the NCS. Data from the three surveys will be available for customers from Q4-2010.


Airborne geophysical project in the Republic of Equatorial Guinea

Posted by AP on Thursday, 10 June, 2010

Sillenger Exploration Corp. has received the historical geological and geophysics data for the Rio Muni region of the Republic of Equatorial Guinea.

Preliminary assessment of the data shows a number of different areas within Rio Muni that indicate the presence of minerals, most notably gold, iron ore, diamonds, colombo-tantalum and bauxite. Except for some artisanal placer gold extraction, the Country currently has no commercial mining activity. The data was provided by the Ministry of Mines, Industry and Energy in advance of the airborne geophysical survey that is expected to commence in July.

Sillenger has retained the services of Fugro Airborne Surveys Corp, to conduct the airborne geophysical survey of the Rio Muni. The upcoming survey will help to reveal the locations of potential deposits, and provide a detailed reading of the subsurface structures.

Fugro Airborne Surveys Corp is a subsidiary of Fugro Group, which was founded in the Netherlands in 1962.

As previously announced, Sillenger, through its relationship with FCMI Global Inc. and its African affiliates, has entered into a contract with the Government of the Republic of Equatorial Guinea to conduct an airborne geophysical survey of Rio Muni region (27,000 sq. km) of Equatorial Guinea, as well as 30 km of Continental Platform (4,500 sq. km) off the Atlantic coastline. Under the contract, Sillenger (FCMI) will be granted exploration mining concessions, including oil and gas concessions, which are revealed by the survey.

Equatorial Guinea, a major offshore oil producer, has a democratically elected government, and is one of the fastest growing economies in Africa. The Government of Equatorial Guinea has a strong desire to diversify its economy by developing its mining industry, and wishes to obtain a geological and geophysical database that will enable the detection of mineral, hydrocarbon and groundwater resources.


The continuing life of old data

Posted by AP on Friday, 4 June, 2010

Bellhaven Copper & Gold Inc. announces that re-interpretation of the 2008 induced polarization (“IP”) data identified multiple areas of relatively low resistivity and high chargeability interpreted to represent potential feeder-zone structures within the high-sulphidation epithermal gold system at Pitaloza. These areas are extensive in size, typically ranging from 100 to >800 m in length, and 25 m to >200 m in width. All of these inferred structures are proximal to weathered silica-altered outcrops. Past sampling has demonstrated a strong association between silica-altered rocks and the presence of gold.

Paul Zweng, Bellhaven’s Interim CEO and Director, commented as follows:

“The re-interpretation of the 2008 IP survey provides greater understanding of the large chargeability and resistivity anomalies measured at Pitaloza. These data suggest that the dimensions outlining these feeder zones are potentially quiet large. In addition, the new geophysical interpretation will aid our exploration efforts going forward. This is because the challenge for geologists exploring high-sulphidation epithermal gold prospects like Pitaloza is to find the gold-bearing feeder structures occurring within widespread areas of steam-heated, acid-sulphate alteration. We have exposed feeder structures in the exploration trenches and they correlate well with the geophysical anomalies. As such, we can now better infer their positions in areas with little-to-no outcrops or exploration trenches. We are currently working to pinpoint these feeder structures by integrating the geophysical data with the geological observations in advance of the upcoming drilling campaign.”

Re-Interpretation of the 2008 IP Survey

In 2008, Bellhaven contracted Fugro Ground Geophysics (Lima, Peru) to conduct a dipole-dipole induced polarization (“IP”) ground survey over the Pitaloza gold project. The survey consisted of a single 1,800-m long line and six 1,000-m long lines over the Bejucosa, Cementerio, and Caracucho prospects at Pitaloza. The IP lines were oriented NE-SW to cross the W-NW trending, structurally-controlled, gold-bearing zones. The dipole-dipole survey used 25-m transmitting dipoles with separations up to 250 m (n = 10), achieving an average depth of penetration of about 125–175 m.

This past April, Bellhaven engaged Dr. Jovan Silic of Jovan Silic and Associates, Australia, to re-interpret the IP data in an effort to define drill-ready targets (see the press release of April 13th, 2010). To interpret the geophysical signature over Pitaloza, Mr. Silic first considered the general alteration-mineralization features of high-sulphidation epithermal gold deposits.

High-sulphidation epithermal deposits result from fluids (dominantly gases) channelled directly from a magma source into overlying wall rocks. These gases alter the country rocks, producing widespread acid-sulphate alteration. The fluids interact with ground water, forming strong acids, which dissolve the surrounding rock and leave behind a residuum of silica (this wall-rock alteration is commonly referred to as “vuggy silica”). Metal-rich brines that also ascend from the magma may then precipitate gold, copper, and other metals within the vuggy-silica bodies as well as the feeder structures.

The use of IP data to identify the various rock types hosting gold within high-sulphidation epithermal deposits proceeded as follows:

1) Vuggy silica and/or massive silica zones, depending on how much of the original porosity remains from the unaltered host rock, may form areas of higher resistivity. If not oxidised (weathered), then these areas may be associated with elevated levels of chargeability.

2) The feeder structures (faults or breccia pipes) may be recognized as zones with relatively low resistivity with moderate-to-high chargeability due to the increase in porosity from fracturing and/or alteration of the rock.

3) Distal clay alteration (typical devoid of gold) is characterized by low resistivity devoid of chargeability.

Based on these criteria, the principal conclusions of the re-interpretation of the Pitaloza 2008 IP data include:

1) The near-surface resistivity patterns are characterized by a number of isolated high-resistivity zones, corresponding to outcropping silica-altered rocks. These near-surface zones are generally devoid of highly anomalous chargeability as a result of the near-surface oxidation of the sulphides to limonite.

2) The deeper resistivity and chargeability patterns highlight a distinct correlation between the relatively low-resistive zones and higher chargeability zones. Some of these higher chargeability zones extend into higher resistivity areas which are bound or “sandwiched” between these deeper zones or relatively low zones of resistivity. These zones may be interpreted as the feeder faults or breccia pipes within the high-sulphidation epithermal system. These feeder faults or breccia pipes constitute the primary exploration target at Pitaloza. Because we do not know the resistivity of the enclosing rocks prior to hydrothermal activity, we cannot be certain if indeed the higher resistivity zones which bound these inferred structures are indeed the product of the alteration, thereby reflecting zones of vuggy or massive silica.

About the Pitaloza high-sulphidation epithermal gold project, Panama

The Pitaloza project, owned 100% by Bellhaven, hosts three high-sulphidation epithermal gold-(copper) prospects: Bejucosa, Cementerio, and Caracucho. High-sulphidation epithermal deposits host half of the known gold resources (80 Moz) in the Caribbean Basin and yield annual production in excess of 3 Moz of gold in Peru, alone.

The current fieldwork program at Pitaloza is directed toward the Bejucosa and Cementerio prospects. At Bejucosa, acid-sulphate leach alteration has been mapped over a 1000 m by 500 m area by previous workers. Bellhaven dug exploration trenches at Bejucosa in 2006 which yielded the following results: Trench 1—52 m of 2.3 g/t Au; Trench 2—16 m of 1.8 g/t Au; Trench 3—12 m of 8.9 g/t Au, and Trench 4—34 m of 0.6 g/t Au. At Cementerio, located 2 km to the north of Bejucosa, acid-sulphate leach alteration has been mapped over an area 1000 m in length by 200 m in width by previous workers. Four trenches dug by Cyprus Minerals in 1993-1994 delivered the following results: Trench 1—15 m of 0.69 g/t Au, Trench 2—127 m of 0.39 g/t Au (including 25 m of 1.28 g/t Au), Trench 3—55 m of 0.23 g/t Au, and Trench 4—25 m of 0.23 g/t Au.


The expanding of Geophysical Surveys at Alicia Project in Peru

Posted by AP on Thursday, 27 May, 2010

Strait Gold Corporation  reports that it is expanding geophysical surveys at its Alicia copper- gold project in Peru to determine the extent of an iron-copper skarn zone (Zone 4) where historical trenching returned 20.2 metres along strike grading 1.7% copper and 0.94 grams per tonne (g/t) gold.

The geophysical program was expanded based on observations in the field during a program of mapping and sampling that is currently under way. Potential for further iron-copper skarn mineralization has been identified to the east of Zone 4, including isolated outcrops of iron-copper skarn. Since much of this area lies below cover, a ground magnetic survey will be conducted over the potential target and an induced polarization survey will be extended to the east of Zone 4 prior to selecting drill targets.

“Zone 4 returned the best gold values on the property as well as good copper values, and if it extends to the east, it could increase the tonnage potential at Alicia significantly,” said Strait Gold President Jim Borland. “Geophysical surveys, along with the mapping and sampling programs we have been conducting to date, will allow us to pinpoint drill collars on the most prospective of several targets we have now identified on the property.”

More than three-quarters of samples at Alicia from a recent program conducted by the Company returned values greater than 1% copper (see news release of March 23, 2010). One set of samples from a new zone (the Extension Zone) returned 5.65% copper, 0.95 g/t gold, and 45.25 g/t silver over 6.0 metres and resampling of one trench (Zone 5) returned 2.35% copper, 0.38 g/t gold and 15.14 g/t silver and 0.015% molybdenum over 16.5 metres.

The Alicia project is located within the Andahuaylas-Yauri Belt, which stretches across much of southern Peru. This highly prospective belt hosts numerous porphyry and skarn deposits, including Xstrata’s Las Bambas deposit (1.1 billion tonnes grading 0.77% copper), Antapacay deposit (720 million tonnes grading 0.56% copper) and Tintaya Mine (78 million tonnes of reserves grading approximately 1.1% copper and 0.16 g/t gold).

The Company is conducting a two-phase exploration program at Alicia. Phase 1 consists of community engagement, surface mapping, sampling and geophysical surveys to identify drill targets. Phase 2 will consist of drilling to test for mineralization at depth. Baseline environmental studies and preparation of an inventory of old mine workings on the property are also being conducted as required for issuance of a drilling permit.

The geophysical surveys are being conducted by Fugro Ground Geophysics Pty. Ltd.

A ground magnetic and TEM geophysical survey was performed over the main skarn area. The results of the magnetic survey are very useful in mapping the intrusive body and indicate magnetic anomalies where no intrusive outcrop has been mapped but has been observed in the field by Strait geologists. The TEM survey produced a few wide, poorly defined anomalies at depth, some of which were drill tested with no significant results (AL-03, not assayed).


About airborne geophysical survey in Nigeria in the last Earth Explorer issue

Posted by AP on Saturday, 1 May, 2010
The survey was initiated by Professor Siyan Malomo, Director General of the NGSA, and it was conducted in two phases. Phase 1 was financed entirely by the Government of Nigeria. All of the airborne geophysical work – data acquisition, processing and interpretation, was carried out by Fugro Airborne Surveys. Phase 1 was completed in September 2007 and included 826,000 line-km of magnetic and radiometric surveys flown at 500 m line spacing and 80 m terrain clearance; and 24,000 line-km of time-domain electromagnetics surveys flown at 500 m line spacing and 80 m terrain clearance using the TEM PEST system. Phase 2, completed August 2009, surveyed blocks not covered in Phase 1. It included 1,104,000 line-km of magnetic and radiometric surveys flown at 500 m line spacing and 80 m terrain clearance. These levels of survey are intensive: often a total of seven aircraft of three different types were active at one time.
“Comprising some two million line-km of three-sensor magnetic data and 256 channel gamma-ray spectrometry, this was not a job to be taken on by the faint-hearted, impatient or ill-equipped,” says Sally Barritt of GeoWitch.
“Full coverage (almost) of the country was achieved using several aircraft over a series of blocks and sub-blocks, the flying of which needed to be coordinated to accommodate the quirks of the Harmattan and rainy seasons, while minimizing the effects of environmental variations on the quality of the data.”

Kirrin Resources is waiting for airborne EM results

Posted by AP on Wednesday, 21 April, 2010

At the end of March Kirrin Resources Inc. announced that it has appointed Fugro Airborne Surveys Corp. of Ottawa to complete a 1,076 line-kilometre magnetic-electromagnetic (EM) airborne survey of its recently acquired Key Lake Southwest uranium property. The Key Lake SW property is located on the southeastern margin of the Athabasca Basin, about 40 km south-west of Cameco’s Key Lake uranium mill, in northern Saskatchewan, Canada.

The airborne survey will utilise Fugro’s fixed-wing Tempest(r) Digital Time Domain Electromagnetic (DTDEM) system which provides maximum quantitative discrimination of relatively near surface (upper 200 to 300 m) conductivity variations. Airborne magnetic surveys map the variation in magnetic susceptibility, which predominantly results from changes in the percentage of magnetite and some other magnetic minerals in the bedrock. The magnetic variations thus allow the mapping of differing lithologies, faults, potential alteration zones, etc. DTDEM surveys map the three-dimensional variation in conductivity that is caused by one or more of mineralogy (e.g., conductive minerals such as graphite or sulphides), intensity of alteration, water content or changes in salinity. The correlation of the magnetic responses with the EM conductive trends enables the indirect geological mapping of bedrock under overburden and possible Athabasca Basin sandstone outliers. As well, the airborne geophysical data can identify anomalies and potential geological targets that may be spatially associated with uranium deposits or alteration zones near such deposits.

Fugro will commence the survey forthwith and Kirrin anticipates receiving data within four weeks and a full analysis and interpretation about another four weeks thereafter.

The eastern margin of the Athabasca Basin is home to the most productive uranium mines in the world with roughly 25% of the world’s uranium production coming from this area. Kirrin‘s target at Key Lake SW is basement-hosted unconformity-type uranium deposits, similar to Cameco’s basement-hosted Millennium Deposit, located 65 km to the northeast.
