Cambria Gold retains Mt. Margaret copper-gold; names Colloton director, Rueckert VP

VANCOUVER, British Columbia, Sept. 17, 2026 (GLOBE NEWSWIRE) -- Cambria Gold Mines Inc. ( TSXV: CAMB; OTCQX: CAMVF ) (“ Cambria ” or the “ Company”) announces that due to the opportunity to realize significant value for shareholders as a potential Tier 1 asset, the Company will retain its ownership in the Mt. Margaret copper and gold porphyry deposit located in Washington State (“ Mt. Margaret ”), deferring the proposed spinout. Based on ongoing discussions with strategic partners, feedback from Cambria’s investors and the strong fundamentals for copper, the Company believes significantly more value can be added by advancing Mt. Margaret as a significant asset within the portfolio, in addition to the Premier Gold Mine Complex and the Red Mountain Gold Deposit located in the Golden Triangle of British Columbia. Cambria will provide updates on the continued drilling, engineering and construction advancements at the Premier Mine Complex and the Red Mountain Gold Deposit in the near future.

To support Cambria’s new vision of advancing Mt. Margaret, the Company is pleased to announce the immediate addition of an exceptional US-based director to the Cambria board: Kim Colloton.

As previously announced, Asa East, Vice-President of Exploration (USA), David Thomas, Vice-President Projects (USA) and Orla Abrahams, Manager, Stakeholder Relations (USA) will continue in their current roles.

“ We see the opportunity to build an exceptional growth-oriented company at Cambria, anchored by near-term gold production at the Premier Gold Mine Complex in Canada and a potential Tier 1 copper deposit at Mt. Margaret. With over one square kilometer of outcropping mineralization at surface, open for expansion in most directions and at depth below 500 meters, the Mt. Margaret deposit represents a unique opportunity in the United States. Through systematic goals including: permitting milestones, infill and exploration drilling, Mineral Resource Estimates and Economic Studies, we feel that we can add substantial value for our shareholders by keeping our portfolio together ,” said Robert McLeod, CEO of Cambria Gold Mines. “ Our Company will be supported by the highly accretive addition of US-based team members, including our new director Retired Major General Kim Colloton, as well as ex-Barrick Vice-President Cleve Rueckert.”

“I am excited about this expanded opportunity, working with an exceptional team focused on building something special,” said Cleve Rueckert. “We think there is substantial value embedded in Cambria’s portfolio of assets and I look forward to helping unlock that value for the benefit of our stakeholders, importantly the communities where we work, our employees and our shareholders.”

Cambria’s US-based management team continues to advance permit applications and environmental studies supporting additional exploration drilling at Mt. Margaret in the near future. The Company has also begun engagement with local communities and county, state, federal and Tribal representatives regarding Mt. Margaret. These early discussions are intended to establish open communication, understand stakeholder priorities, and inform the Company’s environmental, technical and socioeconomic work as the project is evaluated. Additionally, Cambria has completed relogging and geological modelling of available core from the deposit, reaffirming its view of Mt. Margaret as a unique and exceptional copper-gold porphyry deposit.

About the Mt. Margaret Copper-Gold Deposit

The Mt. Margaret deposit is a calc-alkaline porphyry deposit hosting high-grade copper, gold, and molybdenum mineralization located approximately 22 km southwest of Randle, Washington State. The Mt. Margaret Project is primarily located on patented federal mineral claims that are held by Cambria and the United States Federal Government Bureau of Land Management (“ BLM ”) and located on Forest Service land. Through its US entity, Ascot USA Inc. (“ Ascot US ”), Cambria controls 50% mineral rights of select patented claims centered over the deposit with the Federal Government controlling the remaining 50%, as well as other patents in the area. Cambria also controls 100% interest in 184 lode claims surrounding the property. The Company has been advancing discussions with various US Federal Government Departments, including the BLM, regarding future direction for the deposit.

This porphyry system was discovered and actively explored by Duval Corporation (“ Duval ”) from 1971-1980, completing a total of 20,729m over 105 diamond drill holes (Taylor, 1980) 1 . In 2010, Cambria’s predecessor, Ascot Resources Ltd., completed 4,880m of infill diamond drilling over 10 holes, which confirmed and expanded the mineralized zones defined by Duval’s drilling (See Cambria’s News Releases dated October 13, November 3, November 23, and December 1, 2010 and January 12, 2011).

A historical mineral resource was completed by Duval for the Mt. Margaret deposit, totaling 577Mt grading 0.36% Cu, 0.24 g/t Au, 0.011% Mo, and 1.58 g/t Ag (Taylor, 1980) 1 . This historic estimate predates the implementation of National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“ NI-43-101 ”) guidelines and is not compliant with 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 ”). 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. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves and the Company is not treating the historical estimate as current mineral resources or mineral reserves. Further work including quality assurance / quality control procedures, geological modelling, and assay certificate and collar validation by a Qualified Person 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.

Qualified Person The scientific and technical information within this news release has been reviewed and approved by Asa East, CPG, Vice President Exploration (USA) for Cambria Gold Mines Inc. and a non-independent Qualified Person as defined by National Instrument 43-101. Mr. East is a Certified Professional Geologist in good standing with the American Institute of Professional Geologists (AIPG).
