BRALORNE GOLD MINES LTD: WESTERN BK RAISE AVERAGED 35.23 G/T AU OVER A LENGTH OF 36.5 METERS WITH A TRUE WIDTH OF 0.79 METERS
Bralorne Gold Mines Ltd. has released results from the second (western) of two raises driven on the BK vein to define the gold mineralized shoots above the 800 level. The two raises were driven from the drift level to confirm the grade and the limits of potentially economic mineralization encountered in two sections of the drift in 2008.
Western BK raise
The western raise was driven to a total of 36.5 metres (120 feet). The grade of the vein from 15 assay traverses ranges from 1.54 to 136.97 grams per tonne gold (0.045 to 3.995 ounces per ton) with an average grade of 35.23 grams per tonne gold (1.028 ounces per ton) over a true width of 0.8 metre (2.6 feet). The grade of the zone over a minimum mining width of 1.2 metres (four feet) averages 25.2 grams per tonne gold (0.736 ounce per ton) uncut, or 22.9 grams per tonne gold (0.668 ounce per ton) using the historical mine cutting procedure of reducing assays over three to three ounces per ton. The results are comparable with the average grade of the same mineralized shoot on the 800-level drift, which is 24.8 grams per tonne gold over 1.3 metres (0.722 ounce per ton over 4.4 feet) along a strike length of 53.9 metres (177 feet). The vein at the top of the raise is mineralized, indicating that the raise did not reach the upper limit of the gold mineralization.
BK extraction drift
Two hundred eighty feet of the extraction drift has been complete on the BK extraction drift during February, 2010, and also the draw points No. 1 through No. 4. Draw points No. 5 through No. 12 consist of another 360 feet of developments to be completed. When the extraction drift and draw points are done the crews will be ready to start stoping the ore zone. Upon completion the crews will begin to stockpile the company’s target of 30,000 tons of ore to have a year’s worth of production ahead.
Eastern BK raise
As reported in Stockwatch news on Feb. 1, 2010, the eastern raise was driven to a length of 29 metres (96 feet). The grade of the vein from 11 assay traverses ranges from 2.78 to 60.7 grams per tonne gold (0.081 to 1.770 ounces per ton) with an average grade of 20.7 grams per tonne gold (0.604 ounce per ton) over a true width of 0.6 metre (1.9 feet). The average grade of the zone over a nominal mining width of 1.2 metres (four feet) is 11.9 grams per tonne gold (0.348 ounce per ton).
New vein
A new unexpected vein was cross cut in the new 400-level adit, which was recently broken through to the Bralorne 400 level. The vein was encountered at 60 metres from the portal, just east of historic workings on the Coronation or 77 vein. The vein showed a banded texture that is characteristic of ore-bearing veins in the camp so it was explored by drifting to the east 7.3 metres and west 11 metres of the crosscut. The grade of the vein from 10 assay traverses ranges from 0.79 to 66.65 grams per tonne gold (0.023 to 1.944 ounces per ton) with an average grade of 9.95 grams per tonne gold (0.290 ounce per ton) over a true width of 0.8 metre (2.7 feet). The grade of the zone over a minimum mining width of 1.2 metres (four feet) averages 4.4 grams per tonne gold (0.129 ounce per ton) over an average width of 1.3 metres (4.2 feet). Top cutting was not required as there were no extremely high assays. The vein is interpreted to be a split off of the main Coronation (77 vein). Further investigation is planned to determine its potential extensions.

The Bralorne mine is located 150 air miles from Vancouver. The company is redeveloping the former and very successful Bralorne, Pioneer and King gold mines which rich with history, data and potential. From 1928 to 1971, these three operations produced 4.15 million ounces of gold from 7.9 million tons of ore (equalling a grade of 0.53 ounce per ton). Bralorne, Pioneer and King represent the largest historic gold producers in the Canadian cordillera.
