Prime Mining Corp. reported new results from its ongoing drill program at the Company’s Los Reyes gold-silver project. Reported results are from the first holes drilled into a major new discovery, Mina 20/21 (Mina), located 1.3 kilometres northeast of the Guadalupe East deposit, currently the most eastern of the eight-known gold-silver deposits at Los Reyes. Phase 1 drilling of 74 holes, comprising 15,061 metres (“m”), is now complete and 32 drill holes have been reported. Reporting on the remaining 42 holes is forthcoming, pending assays. Highlights: 4.44 grams per tonne (gpt) gold (Au) and 1,060.1 gpt silver (Ag) over 7.5 m (4.8 m estimated true width) etw from 142.5 m downhole; including 3.15 m (2.0 m etw) at 6.62 gpt Au and 1,397.8 gpt Ag and 1.85 m (1.2 m etw) at 6.3 gpt Au and 1,881.0 gpt Ag (drill hole 21Mina-02); 3,243 gpt Ag over 1.15 m (0.74 m etw) with no associated gold from 81.7 m downhole (21Mina- 05); 1.45 gpt Au and 29.3 gpt Ag over 3.7 m (1.85 m etw) from 91.0 m downhole (21Mina-05); 1.72 gpt Au and 29.6 gpt Ag over 3.85 m (3.20 m etw) from 23.7 m downhole (21Mina-06); Six holes were completed at Mina during Phase 1 drilling. 2021 Los Reyes Drill Program: 4 drill rigs currently active at Prime’s 100%-owned Los Reyes project, down from 7 with the onset of the rainy season; 15,000 m Phase 1 drilling is complete, and the 30,000 m Phase 2 program has been started; Permitting activities underway for Phase 2 roads and drill pads. Mina represents an entirely new area within Los Reyes that was unknown to the Company prior to the on-going regional mapping program. As announced March 18, 2020, rock chip sampling of adularia bearing banded quartz veins and quartz breccias at the Mina 20 and Mina 21 adits returned several mineralized intervals including 3.0 m at 29.8 gpt Au and 1,132 gpt Ag; This initial drilling demonstrates the potential for substantial new mineralized zones to be defined at elevations that are near the top of the “boiling zone” and over 250 m higher than the top of the Estaca Vein at Guadalupe East. Geological and structural relationships between the drill intersections and surface geology at the adits are still unclear with only six holes drilled. Mina will be a high priority Phase 2 target with follow-up drilling currently scheduled to start in November 2021, subject to drill permits and new road and drill pad construction for the expanded program; Drill holes 21MINA-01 and 21MINA-02 targeted an east-west structure, one of two structures seen in the adits. 21MINA-02 is the deepest of the six holes completed in this drill program and intersected the mineralized structure at an elevation of 964 m asl.
