Stewart, BC — Mountain Boy Minerals Ltd (“Mountain Boy”) reports that metallurgical studies were completed on core from DDH-12-MON-61 from the Red Cliff property located in the “Golden Triangle” area of British Columbia. Samples were from cut core and included the interval from 173.93 to 190.24 m (Red Cliff #1) and 200-208.99 m (Red Cliff #2). Within the intervals, gold is associated with sphalerite-galena stringers as well a separate pyrite-chalcopyrite stockwork. A summary of the work by SGS Minerals Ltd is quoted below:
“Gravity tests were conducted on the two composites by passing the ground pulp to a Knelson concentrator followed by Mozley table upgrading. The composites responded well to gravity concentration and 54.2% and 78.2% of gold on average were recovered into gravity concentrate at 447 g/t Au and 1618 g/t Au grade respectively for Red Cliff 1 and Red Cliff 2.
Batch cleaner flotation tests were performed on whole ore from the two composites to produce a Cu-Pb bulk concentrate and a zinc cleaner concentrate. The composites responded well to conventional flotation. For Red Cliff 1, the Cu/Pb bulk cleaner concentrate assayed 25.8% Cu, 7.86% Pb, 4.12% Zn and 323 g/t Au at recoveries of 88.1% copper, 79.2% lead and 81.7% gold. For Red Cliff 2, the concentrate assayed 25.7% Cu, 6.98% Pb, 3% Zn and 256 g/t Au at recoveries of 93.1% copper, 67.1% lead and 76.0% gold. The results were achieved from batch cleaner tests and the recoveries will be higher when locked cycle flotation tests are conducted. Optimization is needed to improve zinc flotation for both composites.
Pre-concentration and flotation tests were performed on the two composites and very good results were obtained. The copper grades were 25.2-25.4% at recoveries of 80.8-81.9%. The lead grades in the bulk cleaner concentrates were 6.95-8.58% at recoveries of 66.6-71.5%. The combined Pb recoveries (gravity + flotation) were 76% and 83.1% respectively for Red Cliff 1 and Red Cliff 2. Gold recoveries were high for the two composites and the total gold recoveries (gravity + Cu-Pb Conc) were 90.4% and 96.4% respectively for Red Cliff 1 and Red Cliff 2. The zinc rougher tailings were subjected to cyanidation and additional 4.4% and 1.2% of gold were leached out. The overall gold recoveries were 94.8% and 97.6%, respectively for Red Cliff 1 and Red Cliff 2.”
Ed Kruchkowski, president of the Company states: “We are extremely pleased with the gold recoveries as well as the recoveries for lead and copper. Our view was that only the gold would be a significant credit to the project but it appears that other metals will be as well”.
Drilling is continuing on the north side of Lydden Creek and it is expected that the last hole will be completed in the next few days. Road construction is underway to fix an existing road and create pads for 8 to 10 holes on the Waterpump zone. In addition a surveyor is creating a data base with GPS locations for all holes as well as the elevations. This data will be used to create a new model that shows grade shells. The Company will also use the existing 2007-2012 and 2017 data to prepare a preliminary resource calculation for the Montrose zone.
