Vancouver, British Columbia--(Newsfile Corp. - April 22, 2026) - Cambria Gold Mines Inc. (TSXV: CAMB) (OTCID: AOTVF) ("Cambria" or the "Company") is pleased to announce the completion of additional claim staking at the Mt. Margaret copper-gold porphyry deposit near Randle, Washington. The new staking consists of approximately seven square kilometres of unpatented lode claims surrounding the Company's patented federal claims. The patented claims are held in partnership with the United States Federal Government Bureau of Land Management. The Company has been advancing discussions with various US Federal Government Departments regarding future direction for the deposit.
"The Mt. Margaret deposit is a significant copper-gold porphyry system," said Robert McLeod, President and CEO of Cambria Gold Mines. "With a mineralized footprint starting at surface and spanning over one square kilometre with multiple drill holes ending in mineralization over 400m below surface, this deposit has the potential to be one of the most significant undeveloped copper deposits in the United States. It is our intention to spin this asset out into a new US focused listed entity in the near future."
About Mt. Margaret
The Mt. Margaret deposit is a calc-alkaline porphyry deposit with copper, gold, and molybdenum mineralization located approximately 22 km southwest of Randle, Washington. Duval Corporation ("Duval") actively explored the project from 1971-1980, completing a total of 20,729m over 105 diamond drill holes. In 2010, Cambria's predecessor, Ascot Resources Ltd., completed 4,880m of infill diamond drilling over 11 holes, which confirmed and expanded the mineralized zones defined by Duval's drilling (see January 12, 2011 Press Release: Ascot Resources Drills 496.0 Meters of 0.459% Copper in drill hole eleven on the Mt. Margaret Property7).
A historical resource estimate was completed by Duval for the Mt. Margaret deposit, with 577Mt grading 0.36% Cu, 0.24 g/t Au, 0.011% Mo, and 1.58 g/t Ag (Taylor, 1980 & Derkley et al, 1990).1,2 This historic estimation work predates the implementation of National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI-43-101") guidelines and was not classified based on currently accepted reserve and resource classifications as set forth by the Canadian Institute of Mining and Metallurgy, August 20, 2000 (CIM Guidelines) or the United States Securities and Exchange Commission's Regulation Subpart 1300 of Regulation S-K ("S-K 1300"). Cambria cautions it is not treating the historic Duval work as a current mineral resource estimate, and there has been insufficient work completed by a Qualified Person to do so at any point in the project's history. Furthermore, uncertainty regarding cut off grade, metal prices, modelling methodology, or other parameters and assumptions used in the Duval work could impact the reliability of the historic estimation. Cambria still considers the Duval work relevant given the number of supporting historical drillholes, many of which were confirmed by subsequent Ascot drilling in 2010. Further work including additional infill drilling, geological modelling, and assay certificate and collar validation by a Qualified Person pursuant to NI 43-101 would be required to produce a NI-43-101 or an S-K 1300 compliant resource. There are no guarantees that this additional work would confirm the historical resource estimate defined by Duval.
In addition to the recently staked unpatented lode claims, Cambria retains 50% ownership of patented federal mining claims covering the Mt. Margaret deposit, with the other 50% held by the federal US government. In March 2010 the Company signed an option agreement, whereby it acquired a 100% interest in General Moly Inc.'s 50% interest in the Mt. Margaret property. Cambria has the right to earn a 100% interest in the Mt. Margaret property subject to a 1.5% NSR and a negotiated federal royalty. The Company may purchase one-half of the NSR upon completion of a preliminary economic assessment. The purchase price is negotiable but shall not be less than 50% of the net present value of the NSR.
