Cambria Gold Mines Announces 24.36 g/t Au over 6.3 Meters from Prew Zone; Announces Start of Infill Drilling at Big Missouri and Silver Coin Deposits

Vancouver, British Columbia--(Newsfile Corp. - July 28, 2026) - Cambria Gold Mines Inc. (TSXV: CAMB) (OTCQX: CAMVF) ("Cambria" or the "Company") is pleased to announce additional assay results from the underground infill drilling program at the Prew Zone of the Premier-Northern Light deposit at the Premier Gold Project ("PGP" or the "Premier Project"), located near Stewart in northwestern British Columbia. Results from a total of 3,151 metres over 42 underground drillholes are reported herein. Highlight results include: 24.36 g/t Au over 6.3 m (incl. 76.70 g/t Au over 1.8 m) in hole P26U-0023 13.17 g/t Au over 10.6 m (incl. 64.66 g/t Au over 1.9 m) in hole P26U-0026 8.31 g/t Au over 11.0 m (incl. 22.13 g/t Au over 2.8 m & 17.70 g/t Au over 1.0 m) in hole P26U-0033 3.30 g/t Au over 25.0 m (incl. 42.90 g/t Au over 1.0 m) in hole P26U-0034 7.89 g/t Au over 8.0 m (incl. 17.00 g/t Au over 3.0 m) in hole P26U-0014 "Drilling continues to define wide, high-grade areas as well as important understanding of post mineral faults at the Prew Zone; additional underground infill drilling will recommence subsequent to proposed additional underground development planned for Q4 at Premier-Northern Lights, located adjacent to the Company's 2,500 tonnes per day mill," said Robert McLeod, President and CEO of Cambria Gold Mines. "At the Silver Coin and Big Missouri deposits, our geological teams have remodelled wide zones of gold mineralization associated with contiguous quartz and sulphide breccias that were historically mined in the 1940s and 1990s. Infill drilling is underway on these structures." The 2026 infill program at the Premier Project is focused on providing the drill spacing required for accurate mine planning and development decisions as Cambria advances toward a potential restart of the Premier mill and mining operations at the Premier and Red Mountain Projects. The Company believes that a significant contributor to the difficulties encountered during previous mining operations under Ascot Resources was the lack of sufficient definition drilling as well as accurate geological modelling prior to production. Drilling at 12.5 metre average spacing is proving successful in defining continuity of higher-grade mineralization along a primary quartz-breccia sulfide domain identifiable both in drilling and the existing underground workings. Higher grades (>10 g/t Au) are often associated with visible gold or massive sulfide mineralization hosted in a wider halo of gold-bearing base metal sulfide mineralization. Sections shown in figures 3 and 4 illustrate the continuity of higher grades between drillholes on and along section. These appear to be analogous to what were defined as "ore shoots" during historic mining of the Premier-Northern Light Deposit. The first phase of underground infill at the Prew Zone is now complete, with assay results from an additional 86 drill holes expected over the coming weeks. Once all assays have been returned, the information will be used to develop underground mining plans and guide additional infill drilling for the Prew Zone. The focus of the infill program has moved to two other priority deposits within the Premier Project, with three drills currently turning at the Silver Coin and Big Missouri deposits. Similar to the drilling at Prew Zone, high priority zones at each deposit will be drilled with a tight spacing utilizing surface drill platforms.

The Company maintains a rigorous sampling and QA/QC procedure for the 2026 drill program. Core samples are prepared at the ALS preparation lab in Terrace, BC. The samples are dried and then crushed to specifications of 70% passing 2mm. Crushed samples are riffle split to 1000g and pulverized to 85% passing 75µm. Analytical work for all results is completed by ALS Canada Ltd. which maintains an internal quality assurance and quality control (QAQC) program and is ISO:17025 certified for the analytical methods used in this release. Pulp splits are sent directly from the Terrace preparation facility to the ALS Canada Ltd. geochemistry laboratory facility in North Vancouver for analysis. Each sample is analyzed for gold by conventional 50g fire assay with atomic absorption finish (Au-AA26) and multielement analysis by four-acid digest with an ICP finish (ME-ICP61). Samples over 100ppm gold are re-analyzed by an overlimit 50g fire assay with a gravimetric finish (Au-GRA22). Samples over 100ppm silver are re-analyzed with an ore grade method (ME-OG62) which is a four-acid digest method followed by an ICP-AES finish (up to 1,500ppm). Samples over 1,500ppm silver trigger the overlimit silver fire assay method (Ag-GRA21) which uses a 30g aliquot and gravimetric finish. Sampling and storage activities are conducted at the Company's secure facility in Stewart, British Columbia. The Company maintains a QAQC program that includes the submission and review of coarse blank materials to monitor contamination and certified reference materials to assess analytical accuracy. Core duplicates, crush duplicates and pulp duplicates are used to infer sampling precision and nugget effect.
