Cambria Gold expands Mt. Margaret, plans spinout

CAMBRIA GOLD MINES ANNOUNCES EXPANSION OF CLAIM PACKAGE AT THE MT. MARGARET COPPER AND GOLD PORPHYRY DEPOSIT AND INTENTION TO SPIN OUT THE ASSET INTO A NEW US FOCUSED COMPANY

Cambria Gold Mines Inc. has completed additional claim staking at the Mt. Margaret copper-gold porphyry deposit near Randle, Wash. 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 U.S. 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 chief executive officer 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 400 m 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 U.S.-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 kilometres southwest of Randle, Wash. Duval Corp. actively explored the project from 1971 to 1980, completing a total of 20,729 m over 105 diamond drill holes. In 2010, Cambria's predecessor, Ascot Resources Ltd., completed 4,880 m of infill diamond drilling over 11 holes, which confirmed and expanded the mineralized zones defined by Duval's drilling (see Jan. 12, 2011, press release).

A historical resource estimate was completed by Duval for the Mt. Margaret deposit, with 577 Mt (million tonnes) grading 0.36 per cent Cu (copper), 0.24 gram per tonne Au (gold), 0.011 per cent Mo (molybdenum) and 1.58 g/t Ag (silver). This historic estimation work predates the implementation of National Instrument 43-101 -- Standards of Disclosure for Mineral Projects guidelines and was not classified based on currently accepted reserve and resource classifications as set forth by the Canadian Institute of Mining and Metallurgy, Aug. 20, 2000 (Canadian Institute of Mining 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 drill holes, 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 National Instrument 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-per-cent ownership of patented federal mining claims covering the Mt. Margaret deposit, with the other 50 per cent held by the federal U.S. government. In March, 2010, the company signed an option agreement, whereby it acquired a 100-per-cent interest in General Moly Inc.'s 50-per-cent interest in the Mt. Margaret property. Cambria has the right to earn a 100-per-cent interest in the Mt. Margaret property subject to a 1.5-per-cent NSR (net smelter returns) 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 per cent of the net present value of the NSR.

Qualified person and technical information

The scientific and technical information within this news release was reviewed and approved by Blaine Smit, PGeo, vice-president, exploration, for Cambria Gold Mines and is therefore not independent. Mr. Smit is a qualified person as defined under National Instrument 43-101 and visited the Mt. Margaret project in March of 2026 to review 2010 drill core, property geology and monumented drill collars. Mr. Smit was not involved with the 2010 drill program by Ascot Resources and is relying on the publicly available disclosures and internally available assay and QA/QC (quality assurance/quality control) files, along with physical review of drill core, to verify the results of the 2010 drilling.
