Crowflight to Commence Major Surface and Underground Drilling Program at Bucko Deposit Within the Thompson Nickel Belt
|TORONTO, ONTARIO - CROWFLIGHT MINERALS INC. (TSX Venture Exchange:CML) is initiating a major surface and underground drilling program to upgrade historical (pre NI 43-101) resources (2.5 million tonnes grading 2.23% Nickel and 0.17% copper within a global resource of 19 million tonnes grading 1% Nickel) at the Bucko Deposit in the Thompson Nickel Belt to the Measured and Indicated Mineral Resource categories, which would be used to proceed with a feasibility study (refer to Figure 1 Location Map). |
The initial work by Crowflight in 2004-2005 will include the following :
- a compilation of the existing data to produce a 3D model of the known mineralization,
- outlining a detailed surface and underground diamond drilling to define the ultimate size and grade of the resources down to the 1,000 metre level to NI43-101 standards for Measured and Indicated Mineral Resources,
- acquiring the necessary permits with regards to the development work for the underground diamond drilling, that would include installing a power supply and surface infrastructure to gain underground access, as well as dewatering and rehabilitating the workings,
- Diamond drilling - a minimum 10,000 metre underground drill campaign (complemented by a minimum 5,000 metre surface drilling program),
- Producing an updated mineral resource estimate compliant with NI 43-101,
- Completion of metallurgical and geotechnical studies, as well as investigating the Platinum Group Metals content and distribution,
- Initiating preliminary mine planning and economic analysis for an underground project.
The work is expected to commence in September 2004 and be completed by the second quarter 2005. Crowflight's. Rick Adams, P. Eng., will supervise the engineering and development work required for the underground exploration program; whereas, Peter Karelse, P. Geo., will supervise the exploration work.
GEOLOGICA Inc. of Montreal is currently completing a NI43-101 report for the Bucko Deposit, and it will be available shortly on Crowflight's website at www.crowflight.com and under Crowflight Minerals Inc. on the SEDAR website at www.sedar.com. The report will summarize the historical work and results to date, as well as details of the planned work program.
2004-2005 Program at the Bucko Deposit
The initial discovery hole at Bucko Lake was drilled by Consolidated Marbenor in 1961 - M77B intersected 1.54% Nickel over 6.3 metres. Falconbridge acquired the property in 1962, and conducted numerous ground geophysical surveys and 51 surface diamond drill holes for 20,725 metres (in 1964) to a -610 metre vertical depth. Between 1970 and 1972, Falconbridge excavated a three compartment shaft to -357 metres below surface and completed 1,067 metres of drifting on the 1000 Level (at -305 metre depth). This was followed by 12,690 metres of diamond drilling in 61 underground holes at between 30 and 50 metres spacing. Nickel mineralization was intersected in drilling within an ultramafic unit along a 460 metre strike length. There are 4 Nickel-sulphide lenses, three of which have been followed (by surface diamond drilling in 1990) to a vertical depth of nearly -890 metres. The Nickel sulphide mineralization (contained in pyrrhotite-pentlandite) appears as net-textured and disseminated sulphides, typically containing 0.5 to 2.5% Nickel, and within stringers and massive sulphides, typically containing 10 to 15% Nickel.
A number of separate resource estimates were done by Falconbridge between 1968 and 2000 for the Bucko Deposit using different combinations of surface and underground diamond drill holes and parameters. The most widely used historical resource estimate for the Bucko Deposit was estimated in 1992 (prior to NI 43-101) at 2.5 million tonnes grading 2.23% Nickel and 0.17% Copper included within a global resource of 19 million tonnes grading 1% Nickel. In the opinion of Mr. Alain-Jean Beauregard, Geol., of GEOLOGICA Inc. of Montreal, an independent Qualified Person under NI 43-101 who has reviewed the data and estimation procedures, as outlined in a letter to the Company dated August 19, 2004, the historical resource (both higher grade and global resource) would be reportable as an Inferred Mineral Resource under the guidelines of NI 43-101.
Two scoping studies were previously completed for the Bucko Deposit :
- A 1994 study by Falconbridge, in a report titled Bucko Lake Project, 1994 Pre-Feasibility Study, June 1994, by Francois Pronovost, Falconbridge Project Engineer, for a combined open pit and underground mining operation, and
- A 2001 study by Nuinsco Resources Limited/Micon, in a report titled Review of the Mineral Resources, infrastructure and Operating Plans of the Bucko Lake Nickel Project, March 2001, by Micon international Limited, for a strictly underground mining operation. This study relied on a report titled Resource Estimate of the Bucko Lake Property, Northern Manitoba, by Roscoe Postle Associates Inc. dated June 2000.
Both studies will serve as guidelines for work program and preliminary economic analysis. Crowflight's Sudbury exploration team under Peter Karelse, P. Geo., will undertake the geological work portion of the study, whereas Rick Adams, P. Eng., will supervise the engineering work.
The Bucko Deposit forms part of the recently optioned 190 square kilometre property package located in the Wabowden segment of the Thompson Nickel Belt (TNB), located 100 kilometres south of Inco's producing mines of Thompson and Birchtree. Both operations yielded more than 100 million pounds of Nickel in 2003 along the same mineralized belt, and currently host reserves reported to be 34 million tonnes grading 2.19% Nickel and 0.15% Copper. Crowflight and Falconbridge are focussed on outlining significant Nickel mineralization in the Measured and Indicated Mineral Resource categories on all the properties that have the potential to advance to reserves in the relatively short term at the known historical occurrences (at Bucko and Bowden) and from new targets.
