In Q2/24, exploration efforts at Cabin Creek focused on drilling, geologic modeling, and resource assessment to evaluate the economic feasibility of near-term mining of shallow oxide resources. Assay results from the Phase 1 drilling over 17 holes demonstrated 40 feet of oxide gold mineralization, grading 0.58 g/t, starting at a depth of 70 feet.

At Gold Bar South, the Q2/24 drilling program was focused on three areas: North Zone, East Zone, and East Deep Zone. In the North Zone, additional near-surface mineralization was followed by Phase 2 drilling, potentially expanding our mineral resource. These results are expected to be included in geology and block model updates later in 2024. Drilling in the East Zone revealed extensions of mineralization from the existing pit, prompting further testing. In the East Deep Zone, assay results indicated higher-grade oxidized gold mineralization, prompting additional drilling planned for Q3/24.

At the Hunter Target, exploration drilling across six holes was targeting the geologic controls and potential for near-surface mineralization in legacy drill holes. Q2/24 drilling results demonstrated indicated higher-grade oxidized gold mineralization, with additional drilling planned to continue in Q3/24.
