Copper Reef Mining Corporation is pleased to announce results from the "screen metallic" gold assays as well as silver assays on three of the drill holes into the Alberts Lake Gold Zone located in the central Flin Flon Belt of Manitoba. Screen metallic assays is a way to capture coarse gold in drill core samples by pulverizing the entire sample then screening out all the coarse gold before carrying out regular assays on the fine gold that went through the screen. To some extent, this removes the nugget effect. The screen metallic assays of gold were only slightly higher in some holes indicating coarse gold is present only locally and that most of the gold is of fine grain size. This is positive in the sense that wide variations in grade will be minimal and that generally assay results should reflect closely the true grade of the intersection.

From these drill holes, results indicate that only minor coarse gold exists locally and that most of the gold is finely disseminated throughout the deposit. An example of coarse gold portion would be a 4.5 m intersection of DDH-AL1157Btw, which when assayed with the screen metallic method, increased from 10.76 g/t to 12.19 g/t. These recent drill holes were twin holes using HQ of smaller BQ sized core of holes drilled during the 1980's. The larger HQ core is approximate 3 times larger by volume of the older BQ core. The size of the core also appears to have had little effect on the grade between the new and smaller older holes again suggesting that the gold is for the most part uniformly finely distributed throughout the Alberts Lake Deposit.
Regular assays are assays using a 2 assay ton charge.
New Drilling
Copper Reef has finished this portion of the drill program and is awaiting results from the remaining drill holes. A new drill program of 30 drill holes to expand the deposit is planned to start later this fall.
Management is encouraged by: the grade consistency of this twinned hole; the sheer size of the width of gold zone and high grades that are present at Alberts Lake. ,
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 1.0 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 should provide a reasonable sample size to represent the true grade of the deposit.
Commercially prepared standards representing 3 ranges of gold grades are inserted at intervals of 1 in 10 samples. A blank standard 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.
