Copper Reef Mining Corporation is pleased to announce results from the second of four holes twinned on the Alberts Lake Gold Zone located in the central Flin Flon Belt of Manitoba. Drill Hole AL-11-57btw drilled with HQ core was drilled to twin previous Drill Hole AL-57 which had been drilled with small diameter BQ-sized core. The assay results are regular assays using a 2 assay ton charge. Screen metallic assays which capture coarse gold remain to be completed. The Table below is a comparison of the old drill hole and the new twinned hole drilled from the same location and with the same dip and azimuth.
AL -57 (old BQ Drill Hole) AL-11-57btw (New Twin HQ Hole) at the 200m level
25.8 m 4.5 g Gold/t 27.9 m 3.2 g Gold/t
Including 8.5 m 9.6 g Gold/t 12.4 m 6.1 g Gold/t
Higher grade sections returned values in the new hole assaying 10.8 g gold/t over 4.5 m and a separate zone of 13.5 g gold/t over 1.4 m. The overall 27.9 m intersection, reported above, has a true width of approximately 22.0 m (72 feet).
The Alberts Lake deposit has been previously tested over a 500-metre strike length and to a depth of 400 metres and remains open in all directions. Values up to 125 grams per tonne were noted in drill core with the best intersection over all, assaying 10.89 g/t gold over nine metres (9 m) at 225 metres vertical depth. Visible gold was noted in a number of drill sections in association with pyrite and minor chalcopyrite
New Drilling
Currently the Company is drilling a minimum of 10 drill holes into the "Wally zone", a high grade but narrower (2 metre wide) parallel structure to the north and east of the Alberts Lake Zone. The Wally Zone is characterized by galena, chalcopyrite and pyritic "crack and seal" quartz veins, which are different from the predominantly pyritic, intensely sheared quartz veins of the Alberts Zone. All structures in both the Alberts Lake and the Wally Zone remain open along strike and at depth on Copper Reef's 100-per-cent-owned Alberts Lake property, which is comprised of over 88 mining claims totaling 7,500 hectares.
Preliminary assays from Drill Hole AL-11-57btw which twinned the old hole AL-51 drilled in the 80's confirms the high grade nature and wide widths of this earlier intersection .
Quality Control
The Company employs QA/QC protocol on all aspects of its analytical procedures. Core samples are sawn and one half of the HQ core is restored to the core boxes for future reference and one half sent for analysis. Samples of veining or mineralization are taken in approximately 50 cm intervals or less. Sample preparation and analytical work is conducted at TSL labs in Saskatoon, Saskatchewan utilizing fire assaying with a two assay ton charge, with an AA finish. In addition, pulps of the samples are analysed using a multi-acid digest/ ICP-AES and AAS techniques for trace elements. Gold assays above 0.5 g/ t are then re-assayed by the screen metallic method where the entire sample of the sawn core sent for assay is pulverized and screened with a 150 mesh screen to remove the coarse gold and is then assayed separately by fire assay technique, the remaining pulverized core material that passes through the screen will be assayed by four separate two assay ton charges. The average of the 4 assays will be combined, on a weighted basis, with the assay of coarse gold that was captured by the screen to obtain an overall average grade. This method should give a high level of reliability in representing the contained gold in the core. The large size of core and the closely spaced holes should provide a reasonable sample size and spacing to represent the grade of the vein.
Commercially prepared standards representing 3 ranges of gold grades are inserted at intervals of 1 in 10 samples. A blank rock sample of granite is inserted every 20 samples. Stephen Masson M.Sc., P.Geo. President of Copper Reef is the Qualified Person for the Company. He has reviewed the drill core and confirms the assay results.
We seek Safe Harbor.
