Auro Metals intercepts 625.12 m grading 0.64 g/t Au, 0.10% Cu at Santa Barbara

Vancouver, British Columbia--(Newsfile Corp. - July 13, 2026) - Auro Metals Inc.  (TSXV: AURO) (OTC Pink: AURFF) ("Auro" or the "Company") is pleased to announce the second batch of drill assay results for three drillholes from the 2026 Phase I Drill Program at its 100%-owned Santa Barbara Gold-Copper Project (the "Project") located in the Zamora-Chinchipe Province in southeastern Ecuador. Since the commencement of the drill program, 16 holes have been completed and assay results for the first six holes (including the three holes released on June 22, 2026) have been received. SUMMARY OF DRILL RESULTS These three holes were drilled at the southern part of the known mineralized porphyry system of the Project ("Santa Barbara South") which is believed to be the core area of the known porphyry mineralization system.

These holes were designed to test the continuity of mineralization between historical drill intercepts and the extension of mineralization in up-dip and down-dip directions. Results of the drilling are as follows: Drillhole DSB-59 intersected 625.12 metres ("m") grading 0.64 grams per tonne ("g/t") gold ("Au") and 0.10% copper ("Cu") from 81.43m to the end of hole. This hole terminated in mineralized porphyritic diorite due to drilling difficulties.

Drillhole DSB-58 intersected 130m grading 0.60 g/t Au and 0.09% Cu from 12.0m right below overburden sediments. Drillhole DSB-57 intersected 59 m grading 0.67 g/t Au and 0.10% Cu from surface, and 37.5m grading 0.5 g/t Au and 0.10% Cu from 92.5m. All three holes intersected wide mineralization starting from surface or near-surface, with drill intercepts summarized in Table 1 below.

These drill results demonstrate that mineralization is open in both up-dip and down-dip directions, and show good consistency of gold-copper grades. Drillhole specifications of all completed drillholes are pr
