Highlights:

• Auriginal aims to make a new discovery with this 5,200 m drill program, testing for volcanogenic massive sulphide (VMS) mineralization beneath the existing Rogers gold resource.

• All exploration work permits (ATI) have been received, all holes have been spotted in the field, and drill site preparation is underway.

• Drilling will also probe the depth continuation of the historical porphyry-hosted Cu-Au deposit at the 500-m vertical level.

• New drilling will be probed using Borehole EM survey methods to locate the center of gravity of the VMS mineralized system.

Toronto, Ontario--(Newsfile Corp. - February 10, 2026) - Auriginal Mining Corp. (TSXV: AUME) ("Auriginal" or the "Company") is pleased to announce that all necessary work permits have been received and drill site preparation has commenced. The drilling is anticipated to begin March 5.

Drill Program Rationale

The Roger deposit has long been viewed as a porphyry-style Au-Cu system. Auriginal's recent reinterpretation, based on relogging, resampling, geochemistry, and age dating, now suggests that the historical gold-copper deposit may sit below a deeper gold-rich VMS system up stratigraphy.

A continuous, sulphide-bearing marker horizon has been traced 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 depth.

Downhole EM surveys completed on nine historical holes have identified multiple strong off-hole conductors directly beneath and adjacent to the deepest drilling at Roger.

Roger Project Drill Program

Auriginal is planning a diamond drill program to intersect the gold-rich massive sulphide horizon, targeting newly defined conductor plates with the explicit objective of making a new VMS discovery south of the historical intrusive-hosted copper-gold system on the property. All necessary work and site preparation permits are in hand, and drill site preparation is well underway for a March 5 program start.

The 2026 program includes:

• Minimum 5,200 m of diamond drilling of the Roger mineralized system.
  
  
• Testing conductive plates at the 500 m vertical level across 1.5 km of strike (see Figure 1).
  
  
• Downhole EM in every new hole to tighten vectoring toward the core of the VMS system.

This is the first focused drill campaign designed specifically to test this new VMS interpretation and the high-priority targets defined by borehole electromagnetic surveys (BHEM). Drilling will also test the deep continuation of the historical porphyry-style or intrusion-related Au-Cu deposit on the property, which is still open at depth.

3D Resource Model Indicated Strong Potential for Expansion

A preliminary 3D model has been developed using the digital exploration database for the Roger project and rendered using Leapfrog^®. The intent of this exercise was to provide preliminary validation of the historical drillhole data for the property and to identify additional targets of opportunity that enhance the value proposition of the Roger.

A series of 3D plans, geological and resource wireframe cross-sections and longitudinal sections were created. Additional validation of the model using all historical exploration information was also undertaken.

The longitudinal section created from the data shows a significant thickening of the Roger mineralization (see Figure 2) believed to be the axis of an interpreted volcanic dome or cryptodome, the required heat source for a VMS mineralizing system. The most important basemetal sulphide intersections returned from historical drilling (see Kintavar Press Release - November 12, 2025) occur along the NE and SW flanks of the interpreted dome structure axis, in support of the VMS model develop for the property.

We believe that this is strong indication that the Roger porphyry mineralization remains open towards the NE and at depth. A strong Borehole EM (BHEM) was detected from our earlier survey work (see Press Release, November 12, 2025), believe to be related to massive basemetal sulphide mineralization has also been observed in that direction.
