Almadex Samples 0.59% copper and 0.18 g/t gold in Outcrop at Newly-Acquired Porphyry Target in Nevada, USA
VANCOUVER, British Columbia, Feb. 22, 2024 (GLOBE NEWSWIRE) — Almadex Minerals Ltd. (“Almadex” or the “Company”) (TSX-V: “DEX”) is pleased to announce that, further to its news releases of July 11th and December 14th 2023 describing the identification of new targets, it has acquired by staking a 100% interest in the Radio porphyry copper-molybdenum-gold exploration target in Mineral County Nevada, USA.
The Radio project covers a roughly 2.8 by 1.3 kilometre area of hydrothermal alteration developed in volcanic and intrusive rocks and crosscut by mafic intrusive dykes. The observed hydrothermal alteration and zoning is characteristic of porphyry copper systems. To date Almadex has completed a preliminary surface alteration and geologic mapping program along with surface outcrop rock sampling.
First pass surface rock chip sampling has returned important values of copper, molybdenum and gold. A total of 32 samples were collected and assayed during this field campaign, including 31 outcrop samples and 1 talus sample. Of 31 outcrop samples, a total of 5 samples returned greater than 0.05% Cu, and up to 0.59% Cu and 0.18 g/t Au, and three samples returned higher than 100 ppm Mo, and up to 276 ppm Mo (Table 1). The base and precious metal values occur within malachite-stained mafic dykes and magnetite veined intrusive rocks. Fluid inclusion petrography was carried out on select samples of vein material. This work confirmed the fluid inclusion signature of a porphyry system with one sample displaying the distinctive characteristics of A-type porphyry veins.

The alteration mapping has identified minor zones of pyrophyllite and kaolinite alteration considered representative of an advanced argillic altered zone interpreted to be the remnants of an eroded lithocap. Importantly a 2.8 km phyllic alteration trend was also defined which is characterised by high crystallinity muscovite and paragonite. The phyllic zone is bordered by propylitic chlorite and epidote alteration. These alteration minerals were identified using a Terraspec mineral spectrometer. This interpretation suggests that a potential porphyry deposit could be located at shallow depths from the current surface.
J. Duane Poliquin, Chairman of Almadex commented, “Radio is the result of first principals based conceptual exploration. We hope to make more additions to our project portfolio in 2024 and to advance Radio towards a drill decision. Our CAD$17 Million cash position as of Q3 2023 gives us the luxury of advancing these projects in the manner best suited for shareholders. We have a track record of discoveries, and we feel the varied and exciting projects in our portfolio have the potential to add to that record.”
Lithocaps are extensive areas of hydrothermally altered rocks that occur above or adjacent to intrusive rocks and related porphyry deposits. The hydrothermal alteration forms when ascending high temperature magmatic fluids are released from the source intrusion below and alter permeable and reactive rocks occurring above and or adjacent. Lithocaps can be over 10 by 10 km in surface area and over 1 km thick. The alteration mineral assemblages vary, usually with distance from the intrusive source. Often more neutral and higher temperature stable alteration mineral assemblages are seen at depth, closer to the source intrusion and potential porphyry deposit. More acid and lower temperature stable assemblages generally occur higher up and farther away. Mapping of alteration minerals and geochemical analysis using soil and rock samples can map these changes in mineralogy. This mapping can then provide a vector towards potential underlying porphyry systems. If large areas of lithocap alteration are well preserved, they can obscure deep unexposed porphyry and other styles of mineralisation. If no mineralisation is present at surface, drilling based on vectors provided by geochemical and alteration vectors is the best way to explore for buried deposits.
