92 ENER 92 Energy Limited announced highly promising results from a recent geophysical program completed at the Gemini uranium project in Canada's Athabasca Basin. In October 2022, Discovery Geophysics International completed 23.4 line-km of ground based electromagnetic (EM) surveying, starting over the GMZ uranium discovery and continuing approximately 600 m to the north. Three high-priority EM conductors have been identified by the survey, which are interpreted to reflect the presence of graphite.
One of the EM conductors is located directly at the GMZ and appears closely associated with the graphite altered basement rocks directly underlying the uranium mineralisation. Two additional EM conductors have been identified north of the GMZ (the GMX) and are interpreted to be a 600 m extension of the EM conductor at the GMZ. The third conductor was identified 350 m east of the GMZ, in an area which based on nearby drilling by 92 Energy, may be overlain by sedimentary rocks of the Athabasca Supergroup.
The combination of Athabasca Supergroup sedimentary rocks overlying a graphitic fault zone represents an attractive exploration area to host high-grade uranium at the unconformity. Additionally, a review by the Company of a historical VLF electromagnetic survey conducted by Uranerz Exploration and Mining Limited in 1979 has relocated a series of significant north-east trending EM conductor axes in the western GMX. In addition to the EM survey, 288 line-km of drone magnetic surveying was completed over an area starting south of the GMZ and extending 4 km to the north through the GMX.
A structural interpretation of the magnetic survey results has identified a 2.8 km-long fold trend extending north of the GMZ where prospective interpreted flexures in the basement geology are crosscut by regional magnetic lows, interpreted to be faults. Locations where these flexures in the basement geology are coincident with interpreted faults and EM conductor axes present analogues to the structural setting and geophysical expressions of the GMZ. Based on the results of the EM and magnetic surveying, a number of high priority targets have been identified for testing during the upcoming winter 2023 Gemini drill program.
Additional ground EM coverage is planned along the western limb of the newly recognised fold trend to aid in drill planning. Next Steps: Processing and interpretation of the geophysical data is ongoing. The 92 Energy technical team intends to mobilise to the Gemini project in late January with an initial 4,000 m of diamond drilling scheduled for early February.
Prior to the start of winter drilling, Discovery Geophysics International will conduct additional ground EM coverage over the western GMX to aid in drillhole planning.
