W inte r 2020 27 29 m of a planned 80 m drift to the next drill station. Results from drilling included 0.8 m grading 71.73 g/t Ag, 1.09 per cent Pb and 0.21 per cent Zn. Rokmaster Resources Corp. optioned the Revel Ridge (J&L) property and began underground drilling late in the year to test Au-Ag extensions beyond the historical mine workings and drill sites. The company released a NI43-101 report early in the year and completed preliminary metallurgical test work. The property consists of underground workings and several zones that were historically mined, with previous life of mine average head grades of approximately 6.4 g/t Au, 69.8 g/t Ag, 2.2 per cent Pb and 3.6 per cent Zn. Industrial mineral projects Phosphate exploration continued in the southeast. High Brix Manufacturing Inc. completed an additional 1000 t bulk sample at its Cro project, for testing as fertilizer. Coal projects Teck Coal Ltd. continued exploration drilling in active pits at the Fording River, Greenhills, Elkview and Line Creek mines and continued exploration in their expansion areas. Additional coal projects are also in various stages of environmental assessment. Environmental baseline work continued at the Michel Coal project (North Coal Limited) and at Crown Mountain (Jameson Resources Limited). Both projects also continued design studies on treatment options to comply with water quality guidelines. Jameson also released a bankable feasibility study for Crown Mountain, outlining 1.7 Mty of saleable coal and 57.5 Mt over a mine life of 15 years. SOUTHEAST REGION Precious metal projects After pausing to develop COVID-19 protocols, Osisko Gold Royalties Ltd. began drilling in existing resource and new areas of the Cariboo Gold project, following up on earlier results. The company planned about 40,000 m of drilling and, in October, to increase the number of rigs from three to eight and place the project in a new company (Osisko Development Corp.). To date, the highest grade intersection is 6,530 g/t Au along 0.50 m. The company started a bulk sample at Cow Mountain using underground access from the Bonanza Ledge Access Road. The project is in the early engagement phase of a provincial environmental assessment. Osisko updated the project description in 2020 with an increase in proposed average production rate from 4,000 tpd to 4,750 tpd and a mine life of up to 15 years. Before the most recent drilling, Measured and Indicated resources were 19.531 Mt grading 4.7 g/t, with Inferred resources of 19.252 Mt grading 4.0 g/t. The smaller Bonanza Ledge II mine is in development and expected to produce in 2021 with a two-year mine plan. In an early spring round of drilling at FG, Kore Mining Ltd. reported intersections of 32 m of 3.0 g/t Au near surface, 11.0 m SOUTH CENTRAL AND SOUTHWEST REGIONS 10:31 AM golder.com We thrive on challenges Mines go deeper. Regulations are more complex. Stakeholders are paying attention. We're not in mining because it's easy.
