Bralorne Gold Mines Ltd. (the "Company") provides the following update of results at the Bralorne mine project located 240 km north of Vancouver, British Columbia, where the Company is exploring, developing and building a new gold mining operation.
BK-3 DEVELOPMENT UPDATE
Underground development is being done in the BK-3 zone to define the mineralized sections and prepare for stope mining. Three sublevels have been developed at 100 foot intervals, the 3700, 3800 and 3900 sublevels, named according to their elevations above sea level in feet. For clarity, this naming convention is different than in the historic Bralorne mine, where the levels are at 125 to 150 foot vertical intervals and are numbered sequentially downward from surface (1st through 45th level or 100 to 4500 level). The BK-3 sublevels 3900, 3800 and 3700 are situated above the main 800 mine level and would equate to historic mine levels 470,550 and 620 respectively.
The 3900 sublevel was driven a total of 213 metres and encountered high grade mineralization over a strike length of 63.6 metres in its western part. Channel sample results for this section range up to 324.4 grams gold per tonne over 2.4 metres width (9.46 ounce per ton over 9.1 feet thickness), and average 59.0 grams gold per tonne uncut over 0.9 metres (1.72 ounce per ton over 2.8 feet thickness). The average grade over a 1.2 metre minimum width is 15.7 grams gold per tonne over 1.3 metres (with high assays cut to 103 grams per tonne or 3 ounce per ton). This section lies above the intercept in drill hole UB12-015 that averaged 409.5 grams gold per tonne over a 2.1 metre core interval (11.94 ounce gold per ton over 7.0 feet) that was announced in a news release dated December 17, 2012.
Channel sample results for the 3800 and 3700 sublevels were announced previously in a news release dated June 18, 2012. The 3800 sublevel was developed along strike a total of 183 metres, and high grade mineralization was encountered over a strike length of 160.0 metres that averaged 68.7 grams gold per tonne (un-cut) over 0.8 metres true thickness (525 feet grading ). The 3800 level is now being extended further westward to test beneath the mineralized section on 3900 sublevel.
The 3700 sublevel was driven a total of 118.9 metres and exposed two parallel veins. East of the cross-cut, the average grade of the main structure over a length of 64.0 metres is 16.9 grams gold per tonne (un-cut) over 0.6 metres true thickness (210 feet grading 0.493 ounce per ton over a 2.0 foot width). West of the cross-cut, the average grade of the main structure over a length of 64.0 metres is 22.2 grams gold per tonne (un-cut) over 0.7 metres width (210 feet grading 0.65 ounce per ton over 2.3 foot width). A parallel vein located 10 metres to the south was exposed over a length of 30.5 metres and averages 44.8 grams gold per tonne (un-cut) over 0.5 metres true thickness (100 feet grading 1.31 ounce per ton over a 1.6 foot width).
Several raises have now been competed between the sublevels and extraction drifts and draw points have been completed on the priority sections on 3700 and 3800 sublevels to provide access for mining. This work has enabled nine blocks to be outlined for mining so far, which could be sufficient for at least one year mill feed at the current milling rate.
Thorough QA/QC protocols are followed on the project by monitoring the results of blank and standard samples inserted at a frequency of 1 in 20 each and re-analysis of check samples at a second laboratory. Drill core and underground channel samples are submitted for preparation and analysis at either ALS Laboratory Group in North Vancouver or SGS Laboratory in Vancouver, both of which are ISO certified and accredited. Gold analyses are conducted on 1 assay-ton aliquots using the fire assay method with a gravimetric finish. Metallic sieve assays are done on all mineralized vein samples. The project is under the technical supervision of Dr. Matt Ball, P.Geo., President and Chief operating Officer of the company and qualified person ("QP") as defined by National Instrument 43-101, who has reviewed the technical content of this release.
