Vizsla Copper Corp. (TSXV: VCU; OTCQB: VCUFF) reported initial assay results from its 2026 diamond drilling program at the Palmer copper-zinc project in southeast Alaska.
Hole CMR26-199 intersected 49.2 meters grading 4.7% copper equivalent from 305 meters downhole. The interval averaged 3.05% copper, 4.85% zinc, 21.88 grams per tonne silver and 0.33 g/t gold.
It included 27 meters grading 8.4% CuEq, including a 13.1-meter copper-rich section grading 10.3% CuEq. That narrower interval contained 9.03% copper, 1.83% zinc, 42.74 g/t silver and 0.78 g/t gold.
Second Hole Supports Downdip Continuity
Hole CMR26-201 tested the targeted high-grade core approximately 50 meters downdip from CMR26-199. It returned 40.4 meters grading 3.0% CuEq from 349.3 meters downhole.
The interval included 25.6 meters at 3.7% CuEq and 12.2 meters at 4.9% CuEq.
Vizsla Copper said the two holes confirmed the high-grade copper core within South Wall Zone 1 and extended the mineralized system downdip. Both intersections will be incorporated into the company’s geological model for the Palmer deposit.
However, the reported intervals are downhole lengths. True widths have not been determined.
Palmer Drill Program Expanded
Vizsla Copper expanded its 2026 drilling program from 10,000 meters to approximately 12,250 meters following improved drilling productivity and encouraging geological observations.
Two rigs are currently operating at the HG Prospect and Palmer Extension target. Results from another 15 holes across the HG, AG, South Wall Zones 2–3 and Waterfall targets are expected from late September through early November, subject to laboratory turnaround times and technical review.
Previously disclosed visual observations from some of those holes are preliminary and do not indicate the grades that assays may ultimately return.
Existing Resource Predates New Drilling
Vizsla Copper acquired full ownership of Palmer in December 2025. The project hosts an indicated Mineral Resource of 4.77 million tonnes grading 1.69% copper and 5.17% zinc.
It also contains an inferred Mineral Resource of 12 million tonnes grading 0.57% copper and 3.92% zinc. Both categories include additional silver, gold, lead and barite.
The estimate has an effective date of Jan. 13, 2025 and predates the current drilling. The new results do not automatically increase the resource; further modeling and an updated estimate would be required.
Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
CuEq Assumptions Require Context
The reported CuEq grades incorporate copper, zinc, lead, silver and gold using assumed prices of $4.50 per pound for copper, $1.50 per pound for zinc, $0.95 per pound for lead, $28 per ounce for silver and $2,100 per ounce for gold.
The calculation applies estimated recoveries ranging from 76.1% for gold to 90.3% for copper, based on metallurgical locked-cycle flotation tests completed in 2018. Barite was excluded from the CuEq calculation.
While the assays add information about grade and continuity within Zone 1, they do not establish a Mineral Reserve or demonstrate that Palmer can be developed economically.
