Auriginal drills 32.6 g/t Au over 1.2 m at Roger

Highlights: Gold-rich VMS thesis confirmed: massive sulphides intersected in Hole AUR-26-03, directly above the Roger porphyry deposit, returned 1.55 g/t Au, 41.2 g/t Ag and 0.18% Cu over 4.2 m, including 2.27 g/t Au, 83.9 g/t Ag and 0.47% Cu over 1.5 m, and 1.64 g/t Au, 11.7 g/t Ag, 0.29% Cu and 0.11% Zn over 4.0 m . High-grade gold intersected at depth: hole AUR-26-04A returned 32.6 g/t Au over 1.2 m . Drilling has expanded the Roger porphyry system 600 m NE and 500 m SW of the historical porphyry-style mineralization and clearly defines the fault offset of the porphyry zone as previously interpreted.

Downhole geophysical surveys identified a strong coincident gravity and electromagnetic anomaly 175 m south of hole AUR-26-06, likely related to a sulphide body. The hole is currently being extended a further 200 m to evaluate the geophysical target in the hanging wall. To date, 7 holes have been completed for 4,857 m, with three holes remaining and one hole extension (AUR 26-04A) in the current program.

An additional $2.0 million is budgeted for a follow-up drill program at Roger later this summer or fall. Toronto, Ontario--(Newsfile Corp. - July 14, 2026) - Auriginal Mining Corp. (TSXV: AUME) (" Auriginal " or the " Company ") is pleased to report updated results from its drill program at the 100%-owned Roger Project. Drilling has expanded the known porphyry copper-gold system and, as the Company predicted, has confirmed a second, distinct style of mineralization on the property: a gold-rich volcanogenic massive sulphide ("VMS") system.

"Our thesis that Roger hosts a gold-rich VMS system is confirmed," said Peter Cashin, Auriginal's CEO. "The massive sulphide mineralization in hole AUR-26-03, together with the visuals from other holes for which assays remain outstanding, gives us the confidence to call this what it is, a VMS system. We are seeing pockets of high-grade mineralizat
