Sun Summit Minerals Corp. (TSX-V: SMN; OTCQB: SMREF) is pleased to provide an update from its current drill program at Buck Main and results from its recently completed property-wide exploration program across the Buck Property, central British Columbia.
- Drilling ongoing: Nine holes have so far been completed at Buck Main.
- Testing for high-grade structures and the limits of the Buck Main hydrothermal system: Six holes have been completed in the core of the Buck Main and three holes on the western margin.
- Discovery of strong copper and silver mineralization: A zone of strong copper (Cu) and silver (Ag) mineralization was discovered approximately 1.5 km west of Buck Main where assays of up to 302 grams per tonne (g/t) Ag and 0.47% Cu have been returned in rock chip samples.
- Soil geochemical anomalies to be evaluated with VTEM: Numerous multi-element soil geochemical anomalies have been identified, which may have additional detailed exploration subsequent to the upcoming property-wide VTEM (Versatile Time Domain Electromagnetic) geophysical survey
Sharyn Alexander, Sun Summit’s President, commented: “We are very pleased with our drilling progress so far. We have completed nine holes with many more holes planned. The focus for drilling is to build on our significant grid-based program and to investigate new target areas as well as the potential for additional high-grade structures within the Buck Main area.
“We are also very excited to announce the discovery of an outcropping zone of strong silver and copper mineralization just west of the Buck Main target known as the CC zone. Sampling there returned impressive results such as 302 g/t silver and up to 0.47% copper. The zone is open in all directions and clearly warrants significant follow-up surveys.
“The Buck property is surrounded by current and past-producing mines as well as multiple advanced-stage development assets. The region has seen a recent resurgence in exploration for copper-molybdenum porphyries as well as epithermal-related gold and silver systems. Our recent reconnaissance-level exploration program across the property has identified multiple geochemical anomalies that suggest proximity to concealed porphyry and epithermal systems. Outcrop is very limited across the property, therefore these prospective areas will be further evaluated with an upcoming property-wide VTEM geophysical survey to develop new drill targets.”
Buck Main Drill Program
The current drill program is designed to follow-up significant results from the recently completed, grid-based 10,327 metre drill program across Buck Main (see news releases dated
Nine holes have so far been completed. Three holes have tested the western extent of the Buck Main system where previous results suggested the system remained open (e.g., holes BK21-059 and BK21-065; news release Feb, 2022), two holes have tested for high-grade structures central to the Buck Main target (e.g., BK20-012; news release January, 2021), and four holes have focused on testing the eastern-extent of breccia-hosted and disseminated mineralization (e.g., BK21-017; news release May, 2021).
Core samples from the first four holes are in the lab and results will be released once received and interpreted.
The focus of the 2021 summer reconnaissance-style exploration program was on the approximately 24 kilometre long, northwest-trending, fault-bound belt of Late Cretaceous Kasalka Group volcanic and volcaniclastic rocks, host to epithermal-related mineralization at the Buck Main target area. The program consisted of geological mapping and prospecting, soil geochemical surveys, and rock-chip sampling in areas of outcropping bedrock.
The CC Zone is centered approximately 1.5 kilometres west of the Buck Main target along the banks of an incised creek. The zone consists of a brecciated and well-mineralized contact between two volcanic units. Mineralization comprises multiple approximately 5 cm wide veins containing variable amounts of copper oxides and silver-bearing sulfosalts and has been traced for 25 metres where the contact is obscured by overburden. Rock chip samples taken in proximity to the contact returned up to 302 g/t Ag, 0.47% Cu as well as 162 g/t Ag, 0.25% Cu (Figure 1). Follow-up work, including grid-based soil-geochemical surveys, detailed geological mapping and prospecting, and IP geophysics, are being planned for CC target area.
Soil Geochemical Surveys
Rocks are poorly exposed across the Buck Property due to the presence of widespread overburden, therefore, the geochemistry of soils are used as a proxy for bedrock geochemistry. Soil samples were collected along property-wide transects and also on focused grids.
Epithermal and porphyry-related pathfinder elements (e.g., antimony, arsenic, zinc, copper, molybdenum) are used to identify areas of high-prospectivity and define footprints of hydrothermally altered bedrock. Areas with high zinc and arsenic are considered priority as a similar element association is associated with Buck-style mineralization.
Numerous open-ended, multi-element pathfinder anomalies were identified (e.g., single line anomalies; Figure 2) and represent key areas that require significantly more sampling to define the extent of the geochemical footprints. These anomalies will also be further investigated during the upcoming property-wide VTEM geophysical survey. This heli-borne survey is designed to map changes in conductivity of the underlying bedrock to help focus exploration on zones of potential hydrothermal-related alteration and mineralization. A full compilation of all exploration data will be reported upon its completion.
