Sun Summit Minerals Corp. announced surface sampling results from the summer 2023 exploration program at its Buck Project in central B.C. The field campaign focused on exploration at several high-priority targets at the Mount Morice and CR areas and resulted in the discovery of a new zone of copper mineralization. Exploration Program: Extensive surface exploration was conducted in the area of Mount Morice and the newly acquired CR project.

This work included detailed geological mapping, sampling, and prospecting, with a total of 230 surface samples collected in high-priority areas (203 rock samples, 17 silt samples, and 10 soil samples). Rock sample highlights from the 2023 program include: Sample J031024: 1.00% Cu & 3.2 g/t Ag, rhyolite/andesite breccia with strong silicification and copper oxide alteration; Sample J030700: 0.94% Cu & 4.1 g/t Ag, similar to sample J031024, strongly Cu-oxidized rhyolite; Sample J030681: 0.64% Cu & 8.1 g/t Ag, drusy quartz veins with disseminated chalcopyrite and strong copper oxides in epidote altered rhyolite; Sample J030756: 0.39% Cu & 2.1 g/t Ag & 81 g/t Mo, hydrothermal breccia with disseminated pyrite ± chalcopyrite-molybdenite and moderate Cu oxides. Other significant copper results from the 2023 program include: Sample J030746: 0.36% Cu; Sample J030667: 0.30% Cu; Sample J030755: 0.19% Cu; Sample J030713: 0.19% Cu; Sample J030718: 0.18% Cu; and Sample J030719: 0.17% Cu.

The Mount Morice target is one of a number of high-priority targets selected for follow-up. This key area is located approximately eight kilometres west of Buck Main on the eastern slopes of Morice Mountain. Field work at Mount Morice included geological mapping, prospecting, and infill silt sampling.

Stream sediment samples from eastern drainages on Mount Morice, downslope from the mapped alteration and vein zones, display highly anomalous gold and silver. Samples from 2022 exploration returned results well above background based on regional stream sediment sampling programs, including 0.26 g/t Au and 0.6 g/t Ag (sample F193428), and 0.25 g/t Au and 0.4 g/t Ag (sample F193427). These results, together with results from mapping and previous selective sampling, suggest the potential of a high-level epithermal system peripheral to a porphyry system.

The anomalous gold+silver in silt samples are downstream of widespread propylitic alteration and local zones of strong phyllic alteration with associated quartz stockworks and sulfide-cemented breccias., The CR area adjoins the Buck project on its western edge and expands the overall property footprint for a contiguous area of 55 mineral claims totalling 52,000 hectares (520 square kilometres). This year represented the first time the CR area was accessed by Sun Summit after its acquisition, and consisted of a first pass reconnaissance assessment of the geological environment and the known zones of mineralization. A large IP chargeability anomaly, located in the northern section of CR at the North Zone, has seen limited exploration.

The anomaly is associated with strong zinc in soils, as well as historic rock samples that have returned values of up to 0.4 g/t Au and 31.7 g/t Ag (sample 3233760). Previous exploration campaigns in the CR area included soil, rock, and silt sampling, airborne and ground geophysics, as well as diamond drilling. The most significant drill intercepts to date are reported from the South Zone, and include 68 metres1 at 0.50% Cu, 0.015% Mo in CR05-03; and 168 metres at 0.37% Cu, 0.017% Mo in CR07-142.

The CR area contains priority targets that warrant detailed systematic follow-up. All known targets show strong porphyry-related mineralization and alteration (distal and proximal assemblages) and are open for expansion. Drill Program Completion: The expansion drill program at Buck Main has been completed, consisting of 13 drill holes for 3,736 metres.

These holes were targeting new zones of potential high-grade and bulk-tonnage mineralization in previously untested areas, both laterally and at depth. Updated 3D modelling at Buck Main led to an improved understanding of the geological and structural controls of mineralization, and drill holes were designed to test fault structures and veins that are often associated with high-grade mineralization elsewhere within the Buck Main zone. Initial drill results indicated significant gold, silver, and zinc mineralization extend laterally and at depth, and support the potential for depth extension of bulk tonnage-style disseminated mineralization being delineated at Buck Main.

The remaining drill holes are being processed for assay and geochemical analysis at the lab. Analytical results will be reported as they become available and undergo QA/QC.
