Prime Mining Corp. announced additional positive results from its continuing 15,000-metre first phase drill program at its wholly owned Los Reyes gold-silver project in Sinaloa state, Mexico. The results include new drill core assays from the Guadalupe East and Zapote South deposits which are two of eight known gold-silver deposits that comprise the current mineral resource at Los Reyes. Twelve drill holes are being reported on, including seven holes from Guadalupe East, and five holes from Zapote South. An additional four drill holes have also been completed at Guadalupe East, each encountering the Estaca vein, with assays pending. A seventh drill rig has been added to the project as the Company pursues completion of Phase 1 drilling prior to the upcoming rainy season. Key Highlights: Drill hole 21GE-03 targeted the Estaca vein at Guadalupe East in an area with no known historic mining or previous drilling to gain more geologic and structural controls and aid in further planning of step-out drilling. Access and topography constraints required hole 21GE-03 to be drilled at a high angle to the interpreted mineralized system. The drill hole successfully intercepted the Estaca vein with a drill core length of 58.0 metres (“m”), 11.6 m estimated true width (“etw”), returning 8.12 grams per tonne (“gpt”) gold (“Au”) and 724.6 gpt silver (“Ag”). Contained within this intercept are three discrete mineralized zones: two upper vein breccia zones separated by 3.5 m (0.7 etw) of waste and a lower mineralized stockwork unit separated from the lower vein breccia by 4.5 m (0.9 m etw) of waste. The first vein breccia intercept was 28.0 m (5.6 m etw) of 11.95 gpt Au and 1,122.1 gpt Ag and the second vein breccia intercept was 10.0 m (2.0 m etw) at 11.17 gpt Au and 909.3 gpt Ag. The lower stockwork unit intercept was 12.0 m (2.4 m etw) at 2.00 gpt Au and 120.9 gpt Ag; Drill hole 21GE-03 intersected the Estaca vein approximately 125 m higher in elevation and nearly 70 m northwest of previously reported hole 21GE-01 which intersected 20.1 m at 3.25 gpt Au 380.0 gpt Ag, including 6.5 m at 6.51 gpt Au and 587.5 gpt Ag. These intercepts, and the historic intercepts in drill holes 12GV-02 and 12GV-03, establish that significant mineralization persists at shallower, open pit depths and the resource has expansion potential to the southeast; Drill holes 21GE-09 and 21GE-10 have also intersected the Estaca vein in previously undrilled areas below historic mining. Drill holes 21GE-11 and 21GE-13 intersected the Estaca vein westwards toward the boundary of the current Guadalupe East pit-constrained Inferred resource. Assays are pending for these four drill holes; and Drill holes 21GE-05 and 21GE-07 intersected new mineralized structures adjacent to the Estaca vein. Hole 21GE-05 intercepted 1.5 m (1.4 m etw) at 10.50 gpt Au and 300.0 gpt Ag and hole 21GE-07 intersected 0.9 m (0.6 m etw) at 93.80 gpt Au and 829.0 gpt Ag. These new structures also potentially expand the current Guadalupe East pit-constrained Inferred resource.
