Sun Summit Minerals Corp. announced that it has commenced a new phase of drilling at its 100% controlled Buck Property, central British Columbia. Two drill rigs are currently on site, and another rig may be added later, dependent on availability. Over 30 drill holes are planned within a footprint of approximately 600 metres by 300 metres. The drill program has three primary objectives: Investigate the extent and continuity of high-grade gold mineralization characteristic of the Trench Zone. All previous Trench Zone holes (e.g., 31.6 g/t gold over 4.0 metres including 246 g/t gold over 0.5 metres; BK21-020) were designed based on results from discovery hole BK20-012 (5.86 g/t gold over 17 metres including 23.05 g/t gold over 3.0 metres). Updated modelling has defined broad northwest trends to high-grade gold mineralization within the target area. New drill holes, all with northeast oriented azimuths, are designed to systematically test these trends for continuity of mineralization. Tightly-spaced step-out holes peripheral to areas of known mineralization together with wider-spaced step-out holes along and across trends will be completed. Twenty four drill holes are initially designed for the Trench Zone. Investigate the strike-extent of near surface, bulk-tonnage gold mineralization characteristic of the Horseshoe Zone. All previous holes in the Horseshoe Zone hit near- continuous, broad zones of breccia-hosted and disseminated gold mineralization (e.g., 1.13 g/t gold equivalent over 87 metres within 0.52 g/t gold equivalent over 409 metres; BK21-033). The zones are unconstrained, and modelling suggests further drilling is warranted to define the extent of bulk-tonnage mineralization. All new drill holes are designed to test the extent of, and the structural relationship between the two key styles of gold mineralization observed within the Horseshoe Zone, being sphalerite-rich sulfide-cemented hydrothermal 'mosaic' breccias (e.g., 1.04 g/t gold over 46 metres including 3.76 g/t gold over 5.7 metres; BK20- 006) and, disseminated throughout volcanic breccias (e.g., 0.58 g/t gold over 127.2 metres; BK20-001). Seven holes are initially planned in the Horseshoe Zone. Investigate the limits of the mineralized hydrothermal footprint. Epithermal-related alteration and mineralization has been intersected in drill holes covering a footprint of approximately 900 metres by 950 metres, including below post-mineralization basalts. The true extent of this footprint is unknown. Additional holes are designed to explore for new mineralized centres within, and outside of the known footprint. Exploration update Property-wide exploration is ongoing (see SMN news release dated August 4th, 2021). Numerous soil- geochemical grids and long property-scale soil transects have been completed totalling over 2,600 samples. Over 220 systematic rock-chip samples have also been collected from newly identified areas of widespread hydrothermal alteration as well as targets identified from a thorough compilation of all available historic exploration data. Soil and rock samples are currently in the lab and results will be released once all data are received and have been interpreted. Management believes this work will yield additional priority drill targets outside the Trench-Horseshoe area.
