09:40 AM EDT, 10/09/2025 (MT Newswires) -- Almadex Minerals ( AAMMF ) announced Thursday that it acquired a 100% interest in the Rattlesnake early-stage exploration project by staking.

A statement noted the Project is located in Arizona and was identified as part of Almadex's ongoing regional exploration program in the western US.

The company said that the Rattlesnake Property covers "a currently mapped area of both quartz alunite and argillic hydrothermal alteration developed in andesite volcanic rocks which are crosscut by altered dykes and dyke swarms."

It added that assay results have been received for 39 of the 96 grab rock samples collected on the Property to date.

Almadex said that of the 39 samples for which results have been received, seven of these samples returned over 100 ppm copper (up to 401 ppm copper and averaging 152 ppm copper for all 39 samples), and one grab sample of vein material in the dyke area returned 326 g/t silver and 1.52% zinc. The rest of the samples were either below detection or not significant, added the company.

The company said it is planning an aggressive soil sampling and induced polarization (IP) geophysical program along with further geological mapping and sampling for the winter of 2025/26 at the Rattlesnake Project to define drill targets for preliminary testing.

"This preliminary work at Rattlesnake has identified a large area of alteration we interpret to be part of a porphyry lithocap," said Almadex's chairman J Duane Poliquin. "We will continue to move all our early-stage projects forward this year along with our plans for drilling our more advanced properties."
