Round 18 Geophysics and Drilling Collaborations Program Final Report Mountain Home Gravity Project

Abstract

E79 Gold Mines Limited, through its wholly owned subsidiary Iguana Minerals, completed a large-scale airborne gravity survey to improve understanding of the structural framework within the Mountain Home Project. The program was designed to identify structures associated with known mineralisation at the Mountain Home Gossan and to highlight additional structural settings with potential to host similar mineralisation across the ~1,300 km2 project area. Traditional field-mapping approaches have proven insufficient due to limited access and the scale of the terrain. The survey acquired gravity data at 400-m line spacing over 540 km2 of prospective stratigraphy within the Mountain Home Inlier, complemented by new magnetic data and a digital terrain model. Preliminary Processing and interpretation of these datasets have delineated numerous structural lineations and trends previously unrecognised. These results have mostly come from the magnetic data. These results significantly enhance the structural understanding of the region and provide a basis for targeted reconnaissance and follow-up exploration, enabling efficient prioritisation of high-potential areas independent of surface access constraints.
