Rae Copper Project

Danvers Prospect – High Grade at Surface Copper

Nunavut, Canada

Danvers High-Grade Copper

Danvers is the most advanced discovery within Rae and the Company’s clearest pathway to a maiden resource. The system carries a historic resource of 4.16 Mt @ 2.96% Cu and has been materially expanded through successive drilling campaigns. Mineralisation sits along the Teshierpi Fault Zone, extends from surface, and remains open along strike and at depth.

The 2026 regional campaign has now confirmed Danvers as a district-scale copper sulphide system, with visible copper observed in every hole drilled into the main structure.

2026 Regional Drilling – District-Scale Confirmation

Wide-spaced step-out drilling along the Teshierpi Fault Zone returned copper across every tested interval, taking the total assayed and mineralised footprint beyond >6 km and confirming copper mineralisation over >3.1 km of contiguous strike.

Geological logging from the most recent step-out holes suggests the prospective corridor may already extend beyond 4.1 km. The system remains open along strike, towards surface and at depth.
