Cambria Gold Mines Intersects 17.95 g/t Au over 22.0 m, Including: 552.0 g/t Au over 0.5 m from Premier Mine Infill Drilling

Vancouver, British Columbia--(Newsfile Corp. - April 21, 2026) - Cambria Gold Mines Inc.(TSXV: CAMB) (OTCID: AOTVF) ("Cambria" or the "Company") is pleased to announce the first results from ongoing infill drilling at the Premier Gold Project ("PGP"), located in northwestern British Columbia. Highlights include:

• 73.86g/t Au over 5.0 m (incl. 552.0 g/t Au over 0.5 m) within 17.95 g/t Au over 22.0 m in P26-2686
• 19.63 g/t Au over 1.6 m within 3.98 g/t Au over 15.4 m in P26-2690
• 8.23 g/t Au over 2.0 m within 3.35 g/t Au over 6.0 m in P26-2689

"This drilling at the 602 Zone is delineating high-grade mineralization, which could be accessed with additional development from the recently constructed underground workings at the historic Premier Mine," said Robert McLeod, President and CEO of Cambria Gold Mines. "Two underground drills are currently delineating the Prew Zone at Premier; our objective is to establish the strong continuity similar to the nine primary shoots that were historically mined at the deposit."

Results from the first five diamond drillholes completed, totalling 1,815m are reported herein from the "602 Zone" of the Premier-Northern Lights ("PNL") deposit. Drilling is focused on infill of Indicated and Inferred Resources at the Premier deposits to provide the necessary drill spacing for development planning. The Company is of the opinion that the lack of infill drilling during development was a critical factor in the difficulties encountered during the mining operations that led to a shut down of operations in 2024.

Gold mineralization is hosted within zones of quartz breccia, with sulfide infill and veining both within and outside the breccia zones. Sulfide mineralization includes pyrite, sphalerite, and galena with lesser amounts of chalcopyrite. Visible gold was identified in 2 of the 5 holes reported in this news release, including an intercept of 552.0 g/t Au over 0.5m in P26-2686 (see Figure 3(a)). This intercept occurs within a wider interval of 17.95 g/t Au over 22.0m represented by a well-defined zone of quartz-sulfide-cemented breccias and veins. Gold veining is interpreted as a later stage event occurring within the wider mineralized zone.

The 602 zone plunges gently to the northwest, and the lower part of the zone is truncated at depth by an interpreted off-setting fault, highlighting a potential future exploration opportunity. The zone remains open down plunge.

The Company is also pleased to announce the commencement of underground drilling, with two diamond drills currently turning at the Prew Zone. Surface drilling will recommence in mid-May when winter conditions end, targeting additional zones of the PNL deposit before moving to the Big Missouri and Silver Coin deposits. The Company intends to complete a total of 27,000m of infill development drilling this year across the Premier Project deposits.

Table 1: Drill Results - Significant Intersections:

1 - ETW = Estimated True Width. All reported intervals are down-hole lengths, with true width estimates ranging from 96-99% of the reported interval. True widths are estimated based on the angle of the drill hole with the interpreted trend of the mineralized zones. 

Composite Calculations for Significant Intersections
Composites for significant intersections were calculated using a 1g/t gold (Au) cut off grade and maximum 3m internal waste. "Including" results are reported at a 10g/t Au cut off grade with maximum 3m internal waste.

Quality Assurance/Quality Control and Sample Preparation

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 most samples for multielement analysis by four-acid digest with an ICP finish (ME-ICP61).

Samples over 10ppm 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, certified reference materials to assess analytical accuracy, and core duplicate samples to infer sampling precision.
