Vancouver, British Columbia--(Newsfile Corp. - July 9, 2026) - Americore Resources Corp. (TSXV: AMCO) | FSE: 5GP | OTC: AMCOF) ("Americore" or the "Company") is pleased to report that interpretation of the recent hyperspectral study has identified additional targets for potential expansion of the mineralization at its 100%-owned Trinity Silver Project in Pershing County, Nevada.
Additionally, the Company has contracted SRK Consulting to complete a new NI 43-101 Technical Report which will include data from lands not in the Company's possession when the October 16, 2025 NI 43-101 Technical Report was prepared (see Company release November 18, 2025).
Hyperspectral study
The Company contracted Apollo Mapping Inc, of Denver Colorado, to acquire 30 cm Maxar Imagery and 3.7-meter SWIR Maxar Imagery over the full property. This imagery, also known as WorldView 3 (WV3) is considered to be the gold standard for satellite imagery. World-leading hyperspectral specialist, Dr. Neil Pendock, of Cape Town, South Africa was contracted to interpret the imagery. The end product is an interpretation of a package of 12 alteration patterns over the property. The package includes opal/chalcedony, calcite, chlorite, alunite, kaolinite, montmorillonite, sericite, buddingtonite, hematite, goethite, jarosite and iron oxide gossans.
Chris M. Healey, P.Geo., Chief Geologist for Americore commented; "The comprehensive detailed nature of the data obtained will require extensive review to determine the best targets for on-going and future exploration. However certain preliminary observations can be made at this time. Newly identified areas, especially to the SE of the Trinity pit appear to be prime targets. The area to the SE of the pit appears to coincide with a significant deep anomaly from an historic IP survey."
For his interpretation, Dr. Pendock has developed a series of indices, as follows;
The Feldspar Hydrolysis and Potassic Index. Approaching a major subvolcanic intrusive core or an intense structural fluid pathway, primary plagioclase is destroyed via base-exchange reactions causing this index to spike. This maps broad, intermediate-to-proximal, alteration envelopes;
The Core Conduit and Acid Leaching Index. This index narrows the focus onto the inner structural pathways, targeting zones where extreme acid leaching and high-temperature boiling took place. It peaks directly over breccia pipes, fault walls, and high-temperature upflow paths where hydrothermal fluids overprinted the original host rhyolite.
The Empirical Classifier-Weighted Alteration index. This index incorporates the empirical machine learning results from the historic open pit centre. By taking linear weights derived from the quadratic classifier and normalizing them against the background country rock, we can project a "Pit Core" signature across the entire 6-km structural corridor. This then serves as a primary target-generation index.
