Bison Resources Limited has completed its maiden high-resolution airborne magnetic and radiometric survey across all four of its project areas in Elko County, Nevada.

The program covered more than 4,000 line-kilometres on 100-metre-spaced east-west lines, providing a new dataset to support geological interpretation and exploration targeting. The survey encompassed the 1.5-kilometre-strike antimony-arsenic anomaly at the Bald Peaks project, where previous reconnaissance sampling identified pathfinder elements and alteration styles indicative of a Carlin-type system.

Bison Resources holds 312 unpatented lode mining claims covering approximately 26.1 square kilometres across the Ruby Lake, Cherry Springs, Bald Peaks, and Medicine Range projects. Nearby project operator Sun Silver Limited reported high-grade silver intercepts beyond its current mineral resource estimate at the Maverick Springs project within the surrounding district in August 2026.

“The completion of our first geophysical survey program marks an important step in advancing our priority prospects towards drilling. As the first high-resolution geophysical survey undertaken across our project areas, the program provides a valuable new dataset to complement our existing spectral data and ongoing surface sampling. Integrating these datasets will allow us to further refine our geological models, prioritise targets and define drill locations ahead of our maiden drilling campaign.”

— Tim Mackellar, Chief Executive Officer

Processing of the magnetic survey data is underway, with inversion modelling and litho-structural basement mapping planned to determine the depth and geometry of subsurface anomalies. Results from this work are expected in early September 2026 to support target ranking and the planning of a maiden drilling campaign across priority prospects.

Contractor selection and program planning are also ongoing for an upcoming ground gravity survey across all four project areas.
