Scout drilling at SWT returned local zones of anomalous Au-Cu compatible with proximity to a porphyry Cu-Au system (e. g. 78 m of 0.08% CuEQ (0.02% Cu, 0.11 g/t Au, 0.4 g/t Ag) in JP22028, as well as local vein-hosted Au-only mineralization (2.7 m of 3.7 g/t Au) in JP22024. At the adjacent Wrich occurrence, Au-Ag-Cu mineralization (108 m of 0.20% CuEQ (0.03% Cu, 0.23 g/t Au, 6.4 g/t Ag) in JP22044 is associated with advanced argillic alteration zones and may represent a higher-level signature of a porphyry Cu-Au system (Amarc March 2, 2023 release).

The 2023 field program was designed to inform the 2024 drilling plans; it included extensive airborne and surface exploration surveys focused on detailed refinement of multiple porphyry Cu-Au deposit targets clustered along mineralized trends across the JOY District (Amarc October 26, 2023 release). In addition to facilitate future drilling, rehabilitation of exploration trail and bridge access to the PINE Cu-Au Deposit in the centre of the JOY tenure and other deposit targets was also completed.

Recent Work

2024 Program

Three deposit discoveries have been made in the JOY District over the past four years. These include the new AuRORA Deposit discovery made in 2024, the Twins Cu-Au Discovery also made in 2024, and the Canyon Cu-Au Discovery made in 2022. The work has also expanded the Canyon Discovery and PINE porphyry Cu-Au deposit (the “ PINE Deposit”), which remain open, and established a pipeline of other porphyry Cu-Au targets across the District.
