The Bonanza Ledge Mine at Barkerville Mountain is BGM's initial production unit. On April 23rd, 2015 BGM announced the completion of Phase I test mining via open pit, with 91,234 tonnes processed at a head grade of 8.66 grams per tonne, yielding 23,726 ounces and a total recovery of 93.4 %.
A new underground mine at Bonanza Ledge was recently permitted (March 2017), which contains a measured and indicated resource of 684,900 tonnes at 7.21 grams per tonne and 158,800 ounces with 18,600 ounces in the inferred category. Bonanza Ledge is situated on the southwest flank of Barkerville Mountain, about two kilometers northwest of the historical Williams Creek, which yielded 85,000 oz of alluvial production. This mine is an underground operation and will focus initially for about three years on the remaining underground resources at both Bonanza Ledge and BC Vein with the potential to develop other deposits nearby on Barkerville Mountain utilizing the same infrastructure.
Bonanza Ledge contains disseminated gold mineralization in a calcareous siltstone while BC Vein is a typical fault hosted quartz pyrite vein hosted mineralization style BC Vein is open at depth and along strike. Further exploration is planned to follow up on several new targets on Barkerville Mountain in the KL Zone and on the 2016 acquired Williams Creek tenements, which will add to the BC Vein strike length.
