Highlights:
- An additional $2.0 million, 6,000-m definition drilling program has been budgeted for late summer or fall. Planning for the expanded program will commence upon completion of the Phase 1 program and receipt of the remaining assay results.
- Drilling to date has shown good depth and strike continuity of the Roger porphyry Cu-Au system as well as extensions to the interpreted VMS horizon.
- A second drill has been mobilized to the property to fast track the current program and to test the SW continuation of the Roger porphyry Cu-Au resource above the 500 m vertical level and to test the continuity of the VMS horizon.
- Strong assays of 1.55 g/t Au, 41.2 g/t Ag, 0.18% Cu over 4.2 m and 1.64 g/t Au, 11.7 g/t Ag, 0.29% Cu and 0.11 % Zn over 4.0 m were returned from the VMS intersections so far.
- Multiple gold intersections have so far been returned from the porphyry zone, the best of which returned 4.01 g/t Au over 2.8 m including 5.39 g/t over 1.5 m, 32.6 g/t Au over 1.2 m and 12.2 g/t over 1.1 m.
Toronto, Ontario–(Newsfile Corp. – July 16, 2026) – Auriginal Mining Corp. (TSXV: AUME) (“Auriginal” or the “Company“) is pleased to report that a second drill has been mobilized to the Roger project to fast track our Phase 1 drill program and prepare for definition drilling of the newly expanded porphyry Cu-Au mineralized system and to better define VMS mineralization intersected to date. Planning for the $2.0 million, Phase 2 program will commence upon receipt of all assay results from the current program and is anticipated to start in late summer or early fall.
“Drilling to date has supported our view of an expanded porphyry Cu-Au resource at Roger below the deepest historical drilling on the property and has confirmed the presence of an overlying gold-rich VMS horizon,” said Peter Cashin, Auriginal’s CEO. “Our work has shown good porphyry-style mineralization characteristic of the historical Cu-Au resource in all holes, which remains open below and to the southwest of the previous limits of Roger zone. Given success of our Phase 1 drilling at Roger, an additional $2.0 million has been allocated to undertake definition drilling to expand the historical resource on the property to the Inferred category. In addition, we intend to reassess the historical resource estimate published in 2018 in consideration of the significant increases we have seen in commodity prices. The expanded Phase 2 program will start later this summer or early fall upon receipt and compilation all data from this summer’s work. The Auriginal Team firmly believes that the best part of the Roger story is yet to come.”

Drill Program Rationale and Results
The Roger deposit has long been viewed as a porphyry-style Au-Cu system. Auriginal’s reinterpretation, based on relogging, resampling, geochemistry, and age dating, suggested that the historical gold-copper deposit sits below an overlying gold-rich VMS system – an interpretation the current drill program has now confirmed. To date, drilling has also confirmed continuity of the Roger porphyry along strike to the southwest by at least 750 m and down to a vertical depth of 525 m.

A continuous, sulphide-bearing marker horizon had previously been defined for at least 1.5 km, hosted in altered felsic to intermediate volcanic rocks typical of VMS environments. Geochemical and geological signatures show strong similarities to Agnico Eagle’s LaRonde 20N massive sulphide deposit, reinforcing the potential for a second, high-grade base-metal deposit at above and to the south of the Roger Cu-Au zone. Digital modeling of the Roger Zone shows the historical resource to be open at depth and along strike and has, thus far, been confirmed by the drilling program.
Expanded Phase 2 Definition Drilling Program
The Company intends to update the historical mineral resource estimate on the Roger Zone to reflect the significantly higher commodity prices since the 2018 estimate and to incorporate the depth and strike extensions of the porphyry zone defined by 2026 drilling (see Figure 1). At the same time, Auriginal will continue to test for further economic zones and vector towards the core of the VMS system. Once the current program is complete and all results have been compiled and integrated, the Company will return to Roger later this summer or fall with a fully funded follow-up program backed by an additional $2.0 million in budget.
