Sun Summit Minerals Corp. announced the discovery of high-grade gold (Au) and silver (Ag) mineralization on the Buck Property, central British Columbia. The 22,000 hectare property, approximately 12 kilometres south of Houston, British Columbia, has excellent nearby infrastructure and allows for year-round road-accessible exploration. Sun Summit recently completed 4,180 metres of drilling in 10 diamond drill holes. Results from all holes are reported. A significant high-grade Au discovery has been made in an area previously untested between the Horseshoe and Trench zones: BK20-012 intersected multiple high-grade Au intervals, 17 metres of 5.86 grams per tonne (g/t) Au including 3 metres of 23.05 g/t Au, and 7.5 meters of 10.19 g/t gold Au including 1.5 metres of 49.60 g/t Au. These new zones are open in all directions. Extensive zones of near-surface Au + Ag mineralization characteristic of the Horseshoe Zone confirms the bulk-tonnage potential of the Buck property. BK20-006 intersected 46 metres of 1.12 g/t gold equivalent (AuEQ) including 24.7 metres of 1.69 g/t AuEQ and BK20-012 intersected 40.5 meters of 1.03 g/t AuEQ. All holes drilled to date intersected significant intervals of Au + Ag mineralization and many holes ended in mineralization. BK20-010 cut 8.1 metres of 1.25 g/t AuEQ and 5.6 metres of 1.95 g/t AuEQ near the bottom of the hole. BK20-012 ended in 12.7 metres of 1.05 g/t AuEQ. The drill program will resume this month with three primary objectives, 1) target new high-grade Au mineralization peripheral to BK20-012, 2) drill new geophysical targets interpreted to be associated with Au mineralization, and 3) expand drilling footprint in zones of near-surface bulk- tonnage style mineralization. This discovery of high-grade gold mineralization is the result of technical team's hard work to develo and apply new exploration models at Buck and commend them on this discovery. Based on new interpretations, changes made during this program included deeper drill holes with different orientations compared to historic drilling. Deeper holes succeeded in intersecting new gold zones below historic drill depths and most of these are wide open for expansion. Better hole orientations have encountered several significant gold intervals at or near surface. Buck Property Drill Program: The primary aim of the recent 2020 drill program was to test the lateral and vertical extent of epithermal- related Au + Ag mineralization outlined by previous drilling and new geological and structural mapping. Ten diamond drill holes totalling 4,180 metres were completed primarily focused on the Horseshoe and the Buck North zones. Horseshoe to Trench Zone: One drill hole tested a large gap in historic drill data between the Trench Zone and the Horseshoe Zone. BK20-012 collared in sphalerite + pyrite + quartz + carbonate cemented dacite clast-bearing breccias with near-consistent Au + Ag mineralization and intersected 19.5 metres of 1.66 g/t AuEQ from near the top of the hole. The hole transitioned into bedded-ash to crystal tuffs cut by quartz-feldspar porphyritic dikes. Peripheral to the dikes and associated with broad zones of pervasive sericite + quartz alteration with disseminated and stringer-controlled pyrite + sphalerite are local zones of high-grade Au mineralization (e.g., 17 metres of 5.86 g/t Au and 7.5 metres of 10.19 g/t Au). The hole ended in 12.7 metres of 1.05 g/t AuEQ hosted in similar sericite + quartz altered lapilli tuffs below a quartz + feldspar porphyritic dike. Additional drilling is clearly warranted to investigate the nature of the structural and/or lithological controls to the high-grade Au mineralization and to further test the near-surface and depth potential for bulk-tonnage Au + Ag mineralization. Assays from BK20-012. Horseshoe Zone: Six holes targeted the extent and potential structural and/or lithological controls on disseminated Au + Ag mineralization in the Horseshoe Zone previously investigated in Phase 1 of the program (BK20-001 and BK20-002). Holes BK20-006, BK20-007, and BK20-009 intersected zones of near-surface, sulfide cemented breccias similar to the top of BK20-012 (e.g., BK20-006, 46 metres of 1.12 g/t AuEQ). These north- west trending breccia bodies are spatially related to the margins of much larger magmatic-hydrotherma polymictic breccias with clast compositions varying from dacite to andesite. Breccia matrix is predominantly composed of quartz + feldspar porphyritic dacite and hydrothermal cement varies from carbonate-dominant to sulfide + quartz + carbonate dominant. All phases of breccias contain Au + Ag mineralization associated with clotted and disseminated sphalerite and pyrite (e.g., BK20-009, 111 metres of 0.52 g/t AuEQ). At depth, all holes intersected thick intervals of dacitic crystal to lapilli tuffs and local intercalations of andesite flows. Hole BK20-010 ended in pervasive sericite altered lapilli tuff with local intrusive clasts with significant Au + Ag mineralization near the bottom of the hole (e.g., 8.1 metres of 1.25 g/t AuEQ and 5.6 metres of 1.95 g/tAuEQ). Mineralization is open in most directions and further drilling is warranted to test the extent of near-surface bulk-tonnage mineralization. Assays from the Horseshoe Zone. Buck North Zone: Three holes targeted the lateral extent of disseminated Au + Ag mineralization north of Bob Creek in the Buck North Zone.
