Glenstar Minerals Inc. (CSE: GSTR) announced on September 29, 2026 that polymetallic mineralization has been confirmed in all 10 completed holes of its Phase 1 drill program at the Wildhorse Project in Mineral County, Nevada. Assay highlights include grades of greater than 1.0% zinc, 31.2 g/t silver, and 0.422% copper across five-foot downhole intervals. Gold assays from selected intervals at both the Coca Cola and Rattlesnake Zones remain pending, making further results a key near-term focus for investors watching the project.

  • Top assay highlights include >1.0% Zn, 31.2 g/t Ag, and 0.422% Cu; 71 samples from Hole RTZRC-6 and gold assays from selected intervals remain outstanding
  • Investors should watch for pending gold assay results and overlimit zinc analysis from Hole CCZRC-3

Phase 1 Drill Results Confirm Mineralization at Coca Cola and Rattlesnake Zones

Glenstar's Phase 1 reverse circulation drill program comprised 10 holes — four at the Coca Cola Zone and six at the Rattlesnake Zone. The release states that mineralization occurs over downhole intervals of approximately 50 to 100 feet, containing elevated silver, copper, lead, and zinc values, as well as within narrower higher-grade intervals of approximately 5 to 25 feet. All mineralized intervals are associated with intense iron oxide flooding of the host rocks, with locally abundant sulfides including pyrite, chalcopyrite, and sphalerite identified in both drill areas. True widths have not yet been determined.

Highlight Assay Grades and Pending Results from Wildhorse Drilling

Standout five-foot downhole interval results reported in the announcement include greater than 1.0% zinc in Coca Cola hole CCZRC-3, 31.2 g/t silver in Rattlesnake hole RTZRC-3, 0.422% copper in Coca Cola hole CCZRC-1, 0.171% copper in Rattlesnake hole RTZRC-5, and 12.5 g/t silver in Rattlesnake hole RTZRC-4. A total of 71 samples from Hole RTZRC-6 remain under assay, and the company is also awaiting overlimit zinc analysis on the greater-than-1.0% zinc sample from CCZRC-3. Gold fire assay results for selected intervals from both zones are also outstanding.

Glenstar to Relinquish 28 Peripheral Claims, Retaining 61-Claim Wildhorse Core

The company disclosed it will not renew 28 peripheral claims staked in September 2025 to the west, south, and southeast of the Coca Cola and Highland Zones. Following trenching and drilling, those claims were determined to no longer be priority areas for expansion exploration. Upon their expiry, the core Wildhorse Property will continue to comprise 61 mineral claims covering approximately 1,220 acres (494 hectares) in Mineral County, Nevada.
