Vizsla Copper’s Palmer silver hits: resource growth lens for mine planners

30 Second Briefing
New drilling at Vizsla Copper’s Palmer volcanogenic massive sulphide project in southeast Alaska has returned high-grade silver from the AG deposit, with hole CMR26-215 cutting 21 metres at 4.79% zinc, 0.14% copper, 116.9 g/t silver and 0.27 g/t gold from 180.3 metres, including 7 metres at 207.5 g/t silver. A second hole, CMR26-211, intersected 37.2 metres at 3.62% zinc and 26.1 g/t silver, including 12.8 metres at 7.79% zinc from 169.5 metres. The results will feed into a Q1 2027 resource update for Palmer, which currently hosts 4.77 million indicated tonnes and 12 million inferred tonnes in a copper-zinc-lead-silver-gold-barite system.
Technical Brief
- Palmer VMS district covers ~330 sq. km in southeast Alaska, ~60 km from tidewater export options.
- More than 96,000 m of historical drilling and US$116 million (C$164 million) invested pre-Vizsla acquisition.
- AG deposit drilling in 2026 is the first activity there since 2019, targeting infill continuity.
- Hole CMR26-211 mineralisation starts at 145.1 m depth, with higher-grade zinc from 169.5 m downhole.
- Existing 2025 indicated resource: 4.77 Mt at 1.69% Cu, 5.17% Zn, 0.14% Pb, 28.4 g/t Ag, 0.29 g/t Au, 20.6% barite.
- Indicated metal inventory equates to 178 Mlb Cu, 543 Mlb Zn, 14.2 Mlb Pb, 4.35 Moz Ag, 43,900 oz Au, 980,400 t barite.
- Inferred resource: 12 Mt at 0.57% Cu, 3.92% Zn, 0.47% Pb, 66.3 g/t Ag, 0.33 g/t Au, 25.5% barite, dominated by AG silver.
- Inferred metal totals 151.5 Mlb Cu, 1.04 Blb Zn, 125.2 Mlb Pb, 25.6 Moz Ag, 128,100 oz Au, 3.1 Mt barite.
- No PEA/PFS has yet been published, so mining method, plant scale and CAPEX remain unconstrained.
Our Take
Vizsla Copper’s Palmer polymetallic resource in southeast Alaska sits alongside the Delta and Helm Bay assets it is acquiring from Agnico Eagle Mines (US$32 million in shares), signalling a deliberate build-out of a regional copper‑zinc‑silver portfolio rather than a single-asset play.
With Palmer already carrying significant contained copper, zinc, silver and barite, the added graphite exposure in this piece via Titan Mining’s planned Anniston Army Depot facility highlights how Augusta Group–linked vehicles are spreading across both base metals and US-designated critical minerals supply chains.
In our database of 1267 Mining stories, relatively few US copper projects combine sizeable barite credits with high-grade silver like Palmer, which could be important for future flow-sheet design and by-product economics if barite and silver pricing remain supportive.
