Auriginal Mining drills wide gold and copper intersections at Roger Project in Chibougamau, Quebec

Auriginal Mining Corp. [TSXV: AUME] reported that encouraging results continue to be returned from Phase 1 diamond drilling at the Roger Project, Chibougamau-Chapais district, Quebec. The new results, in combination with our Phase 2 definition drilling, will supplement an expanded Mineral Resource for the historical Roger Zone being undertaken.

The new assays continue to demonstrate the two features that define Roger’s investment case, exceptional width and consistent grade near surface, punctuated by high-grade gold. Hole AUR-26-07 returned the standout intercept of the program to date, 125.3 metres grading 0.67 g/t gold from 346.0 metres, including 20.0 metres at 1.94 g/t gold, this single intersection extends the Roger zone by at least 125 metres at depth.

Higher in the system, AUR-26-06 cut 34.5 metres of 0.69 g/t Au and 0.14% Cu beginning just 70.5 metres downhole, including 6.0 metres at 1.85 g/t Au and 0.34% Cu, confirming that meaningful copper-gold mineralization starts near surface.

AUR-26-05 added 23.5 metres of 1.12 g/t Au, including a high-grade interval of 12.2 g/t Au over 1.1 metres, while late intercepts of 50.4 g/t Au over 0.5 metres at 572.7 metres and 9.1 g/t Au over 2.5 metres at 596.0 metres depth in AUR-26-06 demonstrates that the high-grade gold endowment persists well below the historical resource.

Each hole reported intersected mineralization over broad intervals, the system remains open in all directions, and each of these intercepts falls above the 0.2 g/t Au cut-off being applied to the revised Mineral Resource Estimate, meaning this drilling is not just extending the geology, it is directly adding to the resource base currently being calculated.

“Drilling continues to support our view of a significantly expanded porphyry Cu-Au resource at Roger below and along strike from historical drilling on the property and has confirmed the presence of an overlying gold-rich VMS horizon,” said Peter Cashin, CEO of Auriginal Mining. “We are seeing strong mineralization in all holes, which remains open below and to the southwest and northeast of the previous limits of Roger zone. Phase 2 drilling is well underway and is showing some of the strongest sulphide mineralization observed to date.”

Auriginal’s Phase 1 drilling program was designed to test extensions of the historical Roger copper-gold mineralization and further evaluate the company’s geological interpretation of the broader mineralized system.

Drilling to date has extended the known porphyry-style mineralization approximately 700 metres southwest and 400 metres northeast of the historical drilling limits, while also extending the depth limits of mineralization by more than 100 metres. The Roger mineralized system remains open in all directions. A total of ten drillholes for 7,325 metres were completed in this Phase of the Roger program.

Auriginal Mining’s Roger Project is surrounded by a growing concentration of large, advanced mineral resources in the Chibougamau-Chapais district. The historic mining camp has produced more than 6.5 Moz of gold and 1.6 billion lbs of copper and is attracting renewed investment from major international mining companies.

Nearby projects include the Nelligan Mining Complex – IAMGOLD: 4.3 Moz Indicated +7.5 Moz Inferred gold, Croteau East Project – IAMGOLD: 640,000 oz. Inferred gold, Chibougamau Project – Central Asia Metals: 14.9 Mt at 3.3% CuEQ_, Windfall – Gold Fields: 7.4 Moz gold resources, including 4.1 Moz M&I and Opemiska – XXIX Metals Corp.: 2.4 billion lbs. at 0.74 % CuEQ.

Following the expansion demonstrated during Phase 1, Auriginal has allocated an additional $2.0 million to Phase 2 definition drilling at Roger. The program is designed to provide sufficient drill density across the newly identified extensions of the Roger mineralized system to support their potential inclusion in a future MRE. Based on PLR’s initial review, drilling at approximately 125-metre spacing has been recommended across portions of the newly defined mineralized extensions to support evaluation for potential classification within an Inferred Mineral Resource.

The company expects the broader resource work incorporating the expanded drilling footprint to follow the October update, with additional resource work tentatively targeted for later in 2026 or early 2027. All currently planned Phase 2 drilling and associated technical work is fully funded.

The Phase 2 drilling is currently of the fourth hole of a twelve-hole, 6,250 m program (see Figure 2). The drilling is planned to intersect the Roger porphyry zone above the Phase 1 drilling at the 375 m and 150 m vertical level. Some of the strongest pyrite-chalcopyrite mineralization was intersected. This new drill core will be sent to our lab for analysis soon.

Auriginal is a Quebec-focused copper and gold company with one of the province’s largest and most diversified exploration portfolios. Its 100%-owned flagship Roger Project hosts a known gold-copper deposit with strong potential to host volcanic-hosted polymetallic massive sulphide deposits.
