Zinc social inventories shrank 1,100 mt on week

King Global Critical Minerals reported results from systematic sampling of the historic Golden Turkey tailings at its Black Canyon project in Arizona. A total of 76 near-surface tailings samples collected on an approximately 30-foot grid returned arithmetic averages of around 3.85 g/t gold, 76.2 g/t silver, 0.44% lead and 0.42% zinc. The company explicitly states that these results characterise only the sampled near-surface population and should not be interpreted as the average grade of the entire Golden Turkey tailings deposit or combined with historical tailings-volume estimates to calculate contained metal. King plans additional vertical sampling, representative bulk-density measurements and metallurgical testing while continuing discussions with the U.S. Forest Service and other regulators regarding potential removal, off-site processing and reclamation of the historic tailings.

Glenstar Minerals reported assay progress from Phase 1 reverse-circulation drilling at the Wildhorse project in Nevada. Ten holes were completed—four at the Coca Cola Zone and six at Rattlesnake—and results received to date show silver-copper-lead-zinc polymetallic mineralisation in all completed holes. Mineralised downhole intervals are approximately 50–100 feet, including narrower higher-grade intervals of around 5–25 feet. One five-foot sample from Coca Cola hole CCZRC-3 returned more than 1.0% zinc and is awaiting over-limit analysis. Seventy-one samples from Rattlesnake hole RTZRC-6 remain under assay, while selected gold assays are also pending. Glenstar states that the reported intervals are downhole lengths and true widths have not yet been determined.

Masivo Silver reported assays from CC-26-001, the first hole of its 2026 drilling program at the Cerro Colorado project in Sonora, Mexico. The hole intersected 32.50 metres from 226.30 to 258.80 metres grading 0.271% zinc, 0.141% lead, 7.0 g/t silver, 0.025% copper and 0.010 g/t gold. A separate 5.10-metre interval from 215.10 metres graded 0.611% zinc, 0.121% lead and 24.0 g/t silver. The hole was terminated at 259.5 metres because of technical drilling difficulties while still within altered and mineralised rock. Masivo plans to integrate the assays with geological, structural, alteration and geophysical information to guide follow-up drilling testing lateral and vertical continuity. The company states that all reported intervals are drilled lengths and true widths have not yet been determined.
