Bison Resources (ASX:BSR) has identified a 1.5km arsenic-antimony surface geochemical anomaly at its Bald Peaks Project in Nevada.
The anomaly is associated with decalcification of host carbonates, silicification, gossanous breccias, and jasperoidal alteration, which indicate a potential Carlin-type mineral system.
The company says the results stem from the first 66 rock chip and float samples collected during preliminary reconnaissance sampling, with the geochemical anomaly also featuring coincident mercury, sulphur, lead, and zinc.
CEO Tim Mackellar says the team is encouraged by the ‘strong’ geochemical anomaly returned from the first reconnaissance sampling program.
“Surface arsenic-antimony anomaly, coupled with strong iron-silica alteration and decalcification are precisely the ingredients we were hoping to find to indicate the presence of a Carlin-type mineral system,” Mackellar says.
“The field crews will now progress with detailed mapping and surface sampling to define high-tenor targets that will be drill-tested for gold mineralisation later in the year.”
The Bald Peaks Project sits directly adjacent to Torex Gold Resources‘ (TSX:TXG) Medicine Springs Silver Project and proximal to Sun Silver‘s (ASX:SS1) 539 million ounce silver equivalent Maverick Silver Project.
The initial fieldwork has validated the company’s targeting model, with the observed geochemical anomalism correlating closely with vectors defined through hyperspectral mapping.
Bison plans to advance a systematic soil sampling program with multi-element analysis for follow-up detailed mapping and sampling.
Other workstreams include geological mapping and airborne magnetic and ground gravity geophysical surveying.
Bison’s Nevada projects comprise 312 unpatented lode mining claims covering approximately 26.1km², situated roughly 80km southeast of Elko within the Carlin Trend.
Bison Resources is a mineral explorer and developer focused on gold, silver, and copper deposits within Nevada’s Carlin Trend.
