Foremost Clean Energy Ltd. announced a ground-based gravity survey will commence in December over its Hatchet Lake Uranium Property ("Hatchet"), located in the eastern Athabasca Basin region (the "Basin") of northern Saskatchewan. The gravity survey is focused on the southern extent of the Richardson Trend where there has been limited drilling. The survey will be conducted by MWH Geo Survey ("MWH"), a leading geophysical contractor with more than 40 years of experience throughout the Basin.
Gravity Survey Details: The program is anticipated to comprise approximately 788 gravity stations collected at 100-metre station intervals on 200-metre line spacing across priority structural corridors on the southeast extension of the Richardson trend extending beyond the Athabasca Basin margin. These measurements will assist in refining subsurface interpretations, mapping density contrasts, and identifying potential zones of hydrothermal alteration associated with uranium-bearing structures. The Hatchet Lake Project covers a significant portion of the Richardson Trend, a well-established basement structural corridor known to host uranium mineralization both on the property and along strike.
Importantly, the southeast extension of the Richardson Trend contains more than 6 km of under-tested conductor strike length. The trend hosts brittle-ductile sheared, graphitic basement conductors, which when reactivated, serve as enhanced hydrothermal fluid pathways that create favourable conditions for the development of basement-hosted and unconformity-related uranium deposits. The structural setting is analogous to other major uranium systems along the eastern Basin margin, such as the La Rocque Corridor which is host to ISO Energy's Hurricane Deposit, and Cameco's La Rocque Lake Uranium Zone.
Historic drilling along the Richardson Trend conducted by Denison Mines Corp. ("Denison", NYSE American: DNN,TSX: DML) returned multiple uranium-bearing intervals and strong alteration consistent with a fertile mineralizing system. Significant past results include: 1.52% U3O8 over 0.15 m in hole RL-13-131; 0.45% U3O8 over 2.3 m in holeRL-13-161.
The 2025 ground gravity survey is designed to identify gravity lows and gradients associated with hydrothermal alteration halos and fault-controlled fluid pathways. Gravity anomalies that overlap with graphitic shear zones, magnetically interpreted structures, and geochemical anomalies will be prioritized for drill testing. The company is planning for an anticipated drill program to commence in early 2026, which will focus on priority targets including those along the Richardson Trend and Tuning Fork Target Area.
