Overview
Arrowhead is surrounded by ground held by Agnico Eagle. Mineralized intercepts on the property point to several styles of gold mineralization, including quartz-carbonate veins associated with east-west trending faults and shear zones.
2026 drill strategy
Opawica holds drill permits covering 25 drill-pad locations and has outlined a strategy of about 10,000 metres of high-priority drilling. The 2022 program tested 13 targets; 11 of 14 holes returned gold zones above 1.0 g/t Au along about one kilometre of strike, and nine target zones from that program remain untested. The property adjoins Agnico Eagle’s LaRonde Complex.
Net proceeds of the August 2026 placement are to be used to drill new high-priority targets at Arrowhead (company news release, August 25, 2026).
How the 10,000 metres break down
Targets were generated with ALS GoldSpot Discoveries' Smart Targeting, which identified 20 high-priority drill-ready zones.
- Western Zone, 4,500 m15 drill targets, high-grade continuity
- Eastern Zone, 2,000 m3 holes, Z-shaped fold hinge linked to IP anomalies
- Seismic targets, 2,000 m2 deep holes of 1,000 m each, from Echo-Geotech's 2021 2D seismic survey
- Historic follow-up, 1,500 m4 holes, near historic hole 95-04
Planned program; subject to change. Total 10,000 m. Source: company news release, November 4, 2025.

Historical results
Historic drill holes on the property intercepted 40 gold-copper mineralized zones, and fine visible gold was reported throughout the historical drilling and on surface. A 2015 geochemical survey showed VMS-style signatures and alteration.
Historical results predate Opawica’s work, are reported as core lengths as disclosed by the Company, and should not be relied upon as current results.
2022 drill program
14 holes, 4,306 metres, 1,590 core samples.

Gold values above 0.5 g/t Au are spread over 800 metres east to west, from surface to 200 metres depth, in the western part of the property. Mineralization is open laterally and at depth.
