The Larder Lake Project covers 84 km² over a series of mining claims. Rosor embarked on an ambitious exploration project covering the entire project, which included 2,000 line-km of drone-borne magnetic data, 1,285 line-km of high-resolution Lidar data, and a geophysical interpretation of the area. The drone project started on May 21, 2024, with the 2,000 line-km of magnetic data acquired over 14 days, and the Lidar data acquired over 10 days. Raw data was processed using Oasis Montaj, as well as a newly developed in-house levelling technique specific for drone-borne magnetic data which vastly improved the final magnetic grids. This levelling technique is still used and improved upon for all surveys Rosor flies.
Geophysical interpretation of the project included full lithological and structural interpretations of the area. This comprehensive study was done using a combination of machine-learning techniques to find linear structures, and qualitative interpretation from magnetics, Lidar, geological maps, and drillhole data. The interpretation was done using in-house techniques to carry out the interpretation efficiently and effectively.
The survey significantly improved the magnetic resolution over the OGS Abitibi Supergrid, highlighting structures and anomalies previously not visible. The geophysical interpretation was successful in highlighting major structures and potential mineralized bodies that enhanced Gatling Exploration's understanding of the geology of the property, with the inversion models successfully mapping out magnetic bodies.
The delivered products, including the selected priority areas, provided to Gatling enhanced their drilling targets, improved site selection for the 2024 field season, and assisted in planning for future exploration projects.
