Bison Resources Limited has commenced a ground-based gravity geophysical survey across its four project areas in Elko County, Nevada.

Field crews from contractor Zonge International have mobilized to complete the survey on a 200-meter by 200-meter grid spacing across the Ruby Lake, Cherry Springs, Bald Peaks, and Medicine Range projects. The program covers 312 unpatented lode mining claims spanning approximately 26.1 square kilometers.

Prior to commencing the gravity survey, Bison Resources completed a maiden high-resolution airborne magnetic and radiometric survey covering more than 4,000 line-kilometres across all four project areas. The company will use the new gravity data alongside these airborne magnetic readings and existing spectral, geochemical, and geological datasets to refine litho-structural interpretations and constrain the extents of intrusions at Cherry Springs and Ruby Lakes.

“This is an important first step for the Company's ground-based exploration program. The gravity survey will sharpen our understanding of the geology beneath all four Nevada Projects, and combined with our airborne magnetic and spectral datasets, will directly guide target generation for our maiden drill program”

— Tim Mackellar, Chief Executive Officer

The survey is designed to delineate potential blind mineralisation and high-density targets associated with intrusive bodies, providing the data needed to guide drill target generation for a maiden drilling program. Results from the survey are expected in October 2026.
