Cambria Gold Mines Inc. (TSXV: CAMB; OTCQX: CAMVF) announced new assay results from the ongoing infill drilling program at the Premier Gold Project (“PGP” or the “Premier Project“), located near Stewart in northwestern British Columbia. Results from a total of 6,923 metres from 70 surface and underground drillholes are reported herein. Highlight intervals include:
- 166.22 g/t Au and 3383 g/t Ag over 3.1 m (incl. 467 g/t Au & 9510 g/t Ag over 1.1 m) in hole P26U-0095
- 18.26 g/t Au and 34 g/t Ag over 9.2 m (incl. 36.70 g/t Au & 48 g/t Ag over 0.9m) in hole P26-2705
- 14.68 g/t Au and 32 g/t Ag over 10.0 m (incl. 57.20 g/t Au & 112 g/t Ag over 2.0 m) in hole P26U-0049
- 37.38 g/t Au and 134 g/t Ag over 5.0 m (incl. 46.18 g/t Au & 165 g/t Ag over 4.0 m) in hole P26U-0051
- 42.88 g/t Au and 207 g/t Ag over 3.0 m (incl. 126.5 g/t Au & 599 g/t Ag over 1.0 m) in hole P26U-0052
- 31.26 g/t Au and 94 g/t Ag over 4.0 m (incl. 135.5 g/t Au & 218 g/t Ag over 0.8m) in hole P26U-0084
“Ongoing infill drilling is showing strong continuity of high-grade mineralization; we are highly encouraged by excellent silver results, in addition to gold. Areas of PNL that were mined historically had high silver content, with over 40 million ounces produced,” said Robert McLeod, President and CEO of Cambria Gold Mines. “Additionally, Cambria is expanding our infill drilling program, currently targeting areas of wide, potentially bulk mineable mineralization within the Premier Mine Complex. With excellent discovery potential throughout the Premier Project and limited drilling outside of the major deposit areas, we will also be testing exploration targets, including a potential new, parallel zone to PNL that was discovered in 2025.”
Infill drilling at the Premier Project is on average 12.5 meter spaced centres to provide the necessary drill spacing for accurate mine planning and increased Mineral Resource confidence. Results continue to define the continuity of gold-bearing semi-massive to massive sulfide and visible gold mineralization that forms within and along the contacts of primary quartz breccia domains. The northeastern extent of the Prew Zone drilling is defining an area of high grade silver and gold associated with silver sulphosalts and native silver or electrum, as represented in hole P26U-0095 (Figures 3 & 5).
Reported results are from underground drilling at the Prew Zone, as well as surface holes infilling other areas of the Premier-Northern Light Deposit. These additional areas are being evaluated and prioritized for the development of stope and underground drilling access in Q4 2026. This includes areas along the main Premier structure to the southwest of Prew Zone, where P26-2705 intersected 18.26 g/t Au over 9.2 metres, ten metres beyond the end of the historic workings. This zone is believed to be continuous with the 602 Zone drilled earlier in 2026 and will be targeted for further follow-up from underground platforms to better define grade and continuity.
Cambria is also pleased to announce an expansion of the Premier Mine Complex infill program to 42,000 planned metres. The increased program scope will include additional infill drilling at the Silver Coin deposit, where visual results so far show impressive intercepts of structurally controlled quartz breccia and sulfide mineralization, often with visible gold. Initial results from the Silver Coin drilling are expected to be released in October 2026. The drilling program is expected to continue until the end of 2026, with additional infill drilling as well as some exploration drilling planned at the Premier-Northern Lights Deposit over the winter months. Exploration drilling will include follow up of hole P25-2673, which was drilled to the north of the mill in 2025 and intersected 16.20 g/t Au over 3.9 meters in mineralization similar to the Premier deposit (see Figure 1 and Cambria News Release dated March 3, 2026).

1 – ETW = Estimated True Width. All reported intervals are down-hole lengths, with true width estimates ranging from 50-99% 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 1 g/t gold (Au) cut off grade and maximum 3 metre internal waste. “Including” results are reported at a 10 g/t Au cut off grade with maximum 3 metre internal waste.

Quality Assurance/Quality Control and Sample Preparation
All samples reported in this news release were obtained from NQ sized drill core. 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.
