Bralorne Gold Mines Ltd.: BK Zone 4th Lift Assays Range up to 5906.8 g/T of Au Over a Width of 0.4 Meters
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 09/23/10 -- Bralorne Gold Mines Ltd. (TSX VENTURE: BPM)(PINK SHEETS: BPMSF)(BERLIN: GV7)(FRANKFURT: GV7)(WKN: A0B75M) (the 'Company') is pleased to report on results at its Bralorne Pioneer Mine property, where high-grade assay results were recently received from on-going surface and underground exploration.
Underground Exploration - BK VEIN
Underground development continues with trial mining (shrinkage stoping) up from the 800 level. The fourth lift averaged 32.2 g/T gold (0.938 oz/ton) over 0.9 meters (1.1 ft) for the vein, with assay results ranging up to 5906.8 g/T gold (172.3 oz/ton) over a width of 0.4 meters (1.4 ft). This high-grade assay supersedes a previous high-grade assay of 799.9 g/T gold (23.33 oz/ton) obtained from lift 3. The full mining width for lift 4 averaged 8.26 g/T gold (0.241 oz/ton) over 1.6 meters (5.3 ft), with the stope ranging from 1.0 to 3.0 meters (3.2 ft to 9.8 ft) wide.
Underground Exploration - North VEIN
The North vein, situated in the historic King mine, is being explored by raises and sublevels to confirm a resource block situated between the 800 and 700 levels. Results so far indicate an average grade of 45.6 g/T gold (1.33 oz/ton) over an average width of 0.5 meters (1.5 ft) for the vein, or 14.6 g/T gold (0.425 oz/ton) over 1.7 meters (5.5 ft) for the development width. Individual vein assays range up to 277.3 g/T gold (8.088 oz/ton) over a vein width of 0.5 meters (1.6 ft). A mineralized zone extending 60 meters in length and 35 meters in height is being explored. Trial mining by modified room and pillar method is planned to follow.
Stockpile and Mill Start-up
As of 15 September, approximately 6400 tons of material at an estimated grade of 12.1 g/T gold (0.352 oz/ton) has been stockpiled at the main 800 level portal and approximately 5200 tons remains in broken inventory underground. The Company is planning to re-start the gold mill this fall at a rate of 100 tons per day. Once the stockpile has been processed successfully, the Company plans to continue mining and milling of all the material available from the North and BK areas. Plans are to continue operations by doing further exploration development of resources identified on four separate veins.
The high variation in assay results is characteristic of the lode-gold style of mineralization and the significant nugget effect due to the presence of coarse particulate gold. As such, all samples of quartz veins are assayed by the metallics screen method, which provides a more reliable assay than standard fire assays. A quality control program is also being followed for all assays, which involves monitoring results of blank and certified standard samples that are inserted in the sample stream at a frequency of 10%. The stockpile grade was determined from assays of approximately 700 samples that were analyzed at the mine laboratory (60%) or at Ecotech Laboratory in Kamloops (40%) by the fire assay method using 1 assay ton charges.
Surface Exploration
Surface diamond drilling has intersected high-grade gold mineralization on the upper part of the BK vein. Holes 165 through 174 were drilled to follow-up previous holes, with positive results obtained for holes 165-169 and 174. Visible gold was noted in five of these holes. The best intercept was in hole 169, which assayed 140.46 g/T gold (4.096 oz/ton) over 0.6 meters. Visible gold was observed in the last hole drilled (hole 174). The holes were drilled to follow-up hole 149 which assayed 43.51 g/T gold (1.269 oz/ton) over 0.9 meters (check assay 104.5 g/T gold), and hole 151 which contained visible gold and assayed 9.5 g/T gold (0.277 oz/ton) over 0.5 meters (1.8 ft). Significant assay results received to date are summarized in Table 1 below.
The Company is excited because these drilling results indicate a new mineralized shoot above the one currently being developed. This new zone could be mined from the decline that was initiated in 2009 to explore the BK vein at the 575 Level.
All holes were drilled at NQ size and the recovered core was split for sample collection. One half of the core was sent for analysis and the other half is stored at the core facility located at the mine site. Samples were shipped to Eco Tech Laboratory Ltd. at Kamloops, BC, and gold geochemical analyses were done by the fire assay method using a 1 assay ton charge. All samples of quartz vein are assayed by the metallics method. Quality control is being achieved by inclusion of reference standards and blank samples in 10% of the samples, and by repeat analyses on selected pulps. Additional analyses of selected samples will be done at a second commercial laboratory as a further check. All assay rejects are being retained at the site for further analysis if required.
