King Global Critical Minerals samples gold and silver at Golden Turkey tailings, Arizona

Vancouver British Columbia – September 29, 2026 – TheNewswire - King Global Critical Minerals Inc. ("King" or the "Company") is pleased to report results from a systematic near-surface sampling program completed over the historic Golden Turkey tailings at the Company's Black Canyon Project in Yavapai County, Arizona.

The 2026 program was designed to characterize the lateral distribution of precious and base metals across the exposed near-surface portion of the historic tailings and builds upon an earlier sampling program completed in April 2024 under the supervision of the Company's independent Qualified Person ("QP").

A total of 76 tailings samples were collected on an approximately 30-foot grid. The samples returned arithmetic averages of approximately 3.85 g/t gold ("Au") and 76.2 g/t silver ("Ag"), with individual results ranging from 0.08 to 22.6 g/t Au and 6 to 601 g/t Ag. The samples also returned average concentrations of approximately 0.44% lead ("Pb") and 0.42% zinc ("Zn").

Of the samples, 17 returned greater than 5 g/t Au, including six samples exceeding 10 g/t Au.

Selected Golden Turkey Tailings Results

Sample J454978 returned the highest gold value of the current program at 22.6 g/t Au, together with 254 g/t Ag, 1.14% Pb and 1.12% Zn. Sample J454974 returned 14.6 g/t Au, 601 g/t Ag, 2.33% Pb, 1.67% Zn and 400 ppm Sb, illustrating the polymetallic character of portions of the sampled near-surface tailings.

The reported averages are arithmetic averages of the 76 near-surface samples and characterize only the sampled population. They should not be interpreted as the average grade of the entire Golden Turkey tailings deposit and should not be combined with the historical estimate of tailings quantity to calculate contained metal.
