Crowflight Provides Update on 43-101 Report
|TORONTO: CROWFLIGHT MINERALS INC. (TSX-V: CML), at the request of the TSX Venture Exchange, wishes to clarify the press release of October 13, 2004, where the Company reported that it had received the Bucko Deposit Report, titled 43-101 Technical Evaluation Report of the Bucko Lake Property, Northern Manitoba, dated September 24, 2004 from Alain-Jean Beauregard (P. Geo.) and Daniel Gaudreault (P. Eng.), both from Geologica Groupe-Conseil Inc. of Val-d'Or, independent Qualified Persons under NI 43-101 standards. The Geologica report states that Roscoe Postle Associates Inc. (RPA) in their report titled Resource Estimate of the Bucko Lake Property, Northern Manitoba, Prepared for Nuinsco Resources Limited, dated June 15, 2002, and validated by Micon International Limited in their report titled Review of the Mineral Resource, Infrastructure and Operating Plans of the Bucko Lake Nickel Project, dated March 2001, produced the most complete and recent resource calculation of the Bucko Deposit.|
RPA classified the resources at the time in accordance with the definitions provided in a September 1996 report entitled "Mineral Resource/Reserve Classification: Categories, Definitions and Guidelines" prepared by the Ad Hoc Committee on Mineral Resource Classification of the Canadian Institute of Mining, Metallurgy and Petroleum (CIM).
The 2000 mineral resources parameters and estimation method were reviewed by Geologica and confirmed that RPA's resources did conform to NI 43-101 standards reportable in the Indicated and Inferred Resource categories. The current Mineral Resources are:
-------------------------------------------------------------------- MINERAL RESOURCE SUMMARY Tonnes % Nickel Undiluted Mineral Resource Summary(a) Indicated Resources 1,218,000 2.71 Inferred Resources 455,000 2.23 (a) 6.2 metres average horizontal thickness Diluted Mineral Resource Summary(b) Indicated Resources 1,461,000 2.36 Inferred Resources 547,000 1.99 (b) 7.4 metres average horizontal thickness, diluted 20% at the average wall rock grade --------------------------------------------------------------------The estimates are primarily based on Falconbridge Limited database from the 1960's thru to the 1990's, with a limited contribution of 13 drill holes from Nuinsco Resources Limited. The data was compiled into a GEMCOM database and consisted of:
The resource calculation was done using a conventional longitudinal polygonal method after performing geological interpretations on cross-sections and longitudinal sections constructed in GEMCOM. After interpretation on cross-section, longitudinal sections were constructed for each mineralized zones (Lower, Middle, Upper and Hinge zones) and drill hole intercepts that met minimum width and cut-off grade (greater than 1.5% Nickel and greater than 3.0 metres horizontal width) were plotted and grouped into blocks representing individual shoots of higher grade mineralization on each horizon. The blocks were established from inspection of diluted grade and horizontal thickness values of the drill intercepts. Each block was numbered thereby giving it an alpha-numeric designation such as M5 (Middle Zone, 5th block).
Mineral resource tonnages were determined by measuring the area of each block on digitized outlines and multiplying by the average of the horizontal thicknesses of all drill holes in each block. The grade of each block was determined from the weighted average grade of the intercepts. Dilution was added by increasing the horizontal width of each intercept by 20% at the grade determined by the wall rock assays. No top cutting of assays were performed.
For resource estimation in the Hinge Zone, RPA performed the initial geological interpretation on plan views to account for the geological complexity in the area related to a steeply south plunging fold on the east-west striking ultramafic unit. Four zones of mineralization were interpreted to occur on four planes parallel to the axial plane of the fold. Otherwise, longitudinal sections techniques similar to those employed on the western limb, were used. The results were tabulated by zone and block, as well as by elevation.
Crowflight is not aware of any material issues, whether be geological, environmental, or legal that could adversely affect the current level of Mineral Resources. In addition, the current Mineral Resources do not have demonstrated economic viability.
