Vizsla Copper Corp. Provides Exploration Update From The 2026 Diamond Drill Program at the Palmer VMS Project In Alaska
Vizsla Copper Corp. has provided an exploration update from its ongoing drill program at the Palmer Copper-Zinc VMS Project located in Southeast Alaska. The 2026 program is advancing on schedule with two diamond drill rigs currently operating. Initial drilling has intersected thick intervals of semi-massive and massive sulphide mineralization within the South Wall Zone while continuing to refine the Company's understanding of the geological and structural controls on mineralization. Assay results from the initial drill holes are pending. Five drill holes have been completed, totaling 2,242 meters of the planned 10,000 meter fully funded program. Thick semi-massive and massive sulphide mineralization intersected in both Zone 1 and Zone 2 of the South Wall Zone. Zone 1 intersected 49.2 meters (estimated true thickness of 39 meters) of sulphide mineralization, including thick copper-rich and zinc-rich massive sulphide intervals. One additional drill hole is planned within the South Wall Zone before drilling advances to the HG and Waterfall regional exploration targets. The 2026 program is designed not only to expand and better define the Palmer Deposit and surrounding prospects, but also to continue advancing the technical, environmental and engineering knowledge required to support future project evaluations. The Company's drill program at Palmer continues to progress on schedule and according to the plan outlined in the June 18, 2026, new release. To date, the Company has completed five drill holes, totaling 2,242 meters, as part of its fully funded 10,000-meter 2026 exploration program. Initial drilling has focused on the South Wall Zone, where the 2023 exploration program identified a high-grade copper-rich core within Zone 1. Two drill holes totaling 750 meters targeted the high-grade Zone 1 and intersected a thick sequence of semi-massive to massive copper-rich (chalcopyrite-pyrite) mineralization. The mineralized interval extended 49.2 meters with 14 meters of massive copper-rich sulphide mineralization with an estimated true thickness of 39.0 and 11.2 meters respectively. A second drill hole successfully intersected the upper portion of the mineralization before entering a highly fractured and faulted area and was terminated early due to drilling difficulties. A third drill hole targeting the high-grade core downdip is currently in progress. Two drill holes also tested the deeper Zone 2 horizon, providing important geological and structural information that will be incorporated into the updated geological model. Samples from completed drill holes have been submitted for laboratory analysis, with assay results pending. Following completion of the South Wall program, drilling will transition to the Company's two highest-priority regional exploration targets, the HG Prospect and the Waterfall Prospect, located between the existing Palmer and AG deposits. Regional exploration will continue throughout the field season and include geological mapping, structural interpretation, high-resolution photogrammetry and target refinement across Mount Henry Clay, Christmas Creek and several additional underexplored areas of the Palmer district. Follow-up drilling will be completed where warranted. All fieldwork activities and work areas have been reviewed and approved under authorizations from the Department of Natural Resources and the Bureau of Land Management. Beyond advancing the geological understanding of the mineralization, the 2026 program is expected to support the broader technical, environmental and engineering evaluation of the project. The first phase of drilling has provided valuable geological information that continues to improve understanding of the Palmer deposit and the structural controls responsible for the high-grade copper mineralization identified in the 2023 exploration program. At the same time, the team continues to advance the engineering, environmental and technical studies necessary to support the long-term evaluation of the Palmer Project. This includes engineering studies evaluating alternative approaches for transportation access, port infrastructure, power supply, workforce availability and supporting infrastructure requirements. These studies will continue over the coming years and will form an important component of future technical studies and evaluations. The Company's exploration activities at the Palmer Project are being conducted under approved State and Federal operating plans. These approvals establish the framework for the Company's multi-year exploration program and authorizes activities including diamond drilling, geological and geophysical surveys, environmental baseline studies, access road maintenance, camp operations and other supporting exploration activities required to responsibly advance the project. These approvals followed established regulatory review processes, including public notice, comment periods, and agency consultation. The most recent approval from the Department of Natural Resources and associated public record are available through the Alaska Department of Natural Resources.
