Almadex Announces Staking of Epithermal Precious Metals Prospect, Idaho USA
VANCOUVER, British Columbia, June 16, 2026 (GLOBE NEWSWIRE) -- Almadex Minerals Ltd. ("Almadex" or the "Company") (TSX-V: “DEX”) is pleased to announce that it has acquired the Fountain Ridge epithermal precious metals prospect in western Idaho by staking. The project is located in a region with significant known epithermal gold-silver deposits such as Grassy Mountain, Oregon and DeLamar, Idaho. The DeLamar deposit in Idaho is located approximately 27 kilometers away from the Fountain Ridge prospect and had reported historic production of ~1 million ounces of gold and 50 million ounces of silver1. The Grassy Mountain deposit is located roughly 58 kilometres from the Fountain Ridge prospect. The information disclosed from nearby properties is not necessarily indicative to the mineralization on the Fountain Ridge property.
The Fountain Ridge prospect covers an area of high level (paleo water table) alteration including replacement silicification, argillic alteration and hot spring deposits including features interpreted to be sinter deposits. The alteration is developed in volcano sedimentary and lacustrine units that are overlain by basaltic flows. No significant gold or silver assays were returned from initial grab samples of alteration taken; however, the alteration is consistent with the paleo water table environment of a fossil geothermal system where significant precious metals values are not expected (photos of various outcrops are shown below). Further sampling, mapping and some preliminary induced polarisation (“IP”) geophysical surveys are planned for the coming months to see if initial drill targets can be generated.
J Duane Poliquin, Chairman of Almadex commented, “We are pleased to further expand our exploration portfolio by acquiring the Fountain Ridge epithermal prospect. We look forward to reporting advances as exploration progresses.”
