VANCOUVER, British Columbia, April 23, 2025 (GLOBE NEWSWIRE) -- Almadex Minerals Ltd. ("Almadex" or the "Company") (TSX-V: 'DEX') is pleased to provide a summary of recent exploration results from the Company's wholly owned New Hope copper porphyry project in Arizona. A focussed one line IP chargeability and resistivity survey was recently carried out. The line was surveyed using the Company's highly experienced in house team and equipment, a 5 kW GDD transmitter and Iris Elrec-6 receivers using a 100 m dipole in a pole-dipole array on 8 levels. Pseudo sections were prepared and the data was inverted using RES2DINV software. The line was surveyed across the approximately 600 metre diameter area where sheeted quartz +/- magnetite veining was previously mapped. This veining has been interpreted to represent the upper portion of a shallowly emplaced and highly preserved porphyry copper system. The results of the geophysical survey outlined an anomaly over 1 kilometre wide defined by elevated chargeability, and coincident with the area of outcropping veins. Almadex is very encouraged by these results which provide further focus for a potential future first pass drilling program to test for a copper porphyry at depth. Almadex has an approved drill permit to conduct first pass drilling on the project. Compiled geophysical, geochemical and geological results will be posted to Almadex's website. Geophysical surveys are not definitive, and the results are still at an early stage of interpretation, with no guarantee of a mineral discovery.
J. Duane Poliquin, Chairman of Almadex commented, 'Project level exploration continues to advance our newly acquired portfolio of high-quality porphyry lithocap targets in the western USA. It is exciting to define a strong geophysical target at New Hope in the same area where mapping at surface has outlined an area of high level porphyry veining. We look forward to further advancing the New Hope project in 2025.'
About the New Hope ProjectThe 958.7 hectare New Hope project is located in southeastern Arizona, near several large porphyry copper deposits currently being mined including Lone Star (approximately 35 kilometres away) and Morenci (approximately 50 kilometres away). The project covers a roughly 3.5 by 1.5 kilometre area of intense hydrothermal alteration developed in volcanic rocks and crosscutting intrusive dykes. The observed hydrothermal alteration is characteristic of the upper levels of a porphyry system. The project was acquired in 2023 by staking and broad scale mapping of the lithocap has been carried out over much of the property. Within the area mapped, exposed advanced argillic alteration was identified to the northeast, and to the southwest an exposed set of porphyry-related veinlets was defined in limonitic alteration. This zone of quartz veining is currently interpreted to represent a potential centre to the porphyry system at New Hope. The observed zone of veining is an approximately 600 metre in diameter semi-circular area. The veins and veinlets are sheeted light to dark grey, semi-translucent quartz and magnetite with banded textures. Fluid inclusion petrography on these veinlets indicate that they were formed by vapour rich fluids. These types of veinlets are interpreted to be typical of shallow-level emplaced porphyry systems and above the level at which main stage porphyry-style copper-gold mineralisation is to be expected. Within this broader area, two inner zones about 200 metres and 100 metres in diameter were mapped where veinlet densities of greater than 10 per metre were observed (see Almadex new release of April 8, 2024).
About Lithocap Alteration ZonesLithocaps 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. 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 acidic and lower temperature stable assemblages generally occur higher 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 porphyries and other styles of mineralisation. If no mineralisation is present at surface, drilling based on geochemical and alteration vectors aided by geophysical data is the best way to explore for buried deposits.
