Auro intersects 542 m grading 0.60 g/t Au and 0.12% Cu at Santa Barbara

Vancouver, British Columbia--(Newsfile Corp. - July 28, 2026) - Auro Metals Inc. (TSXV: AURO) (OTC Pink: AURFF) ("Auro" or the "Company") is pleased to announce the third batch of assay results, of four 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 program, 19 drill holes have been completed and assay results of ten holes (including the six holes released on June 22 and July 13, 2026) have been received. SUMMARY OF DRILL RESULTS These four holes were drilled at the southern part of the known mineralized porphyry system ("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. All four holes intersected wide mineralization starting from surface or near-surface, with highlights of the drilling are as follows: Drillhole DSB-60 intersected 542 metres ("m") grading 0.60 grams per tonne ("g/t") gold ("Au") and 0.12% copper ("Cu") from 198m to 740m, and weak mineralization continued to the end of hole. Drillhole DSB-62 intersected 149.5m grading 0.66 g/t Au and 0.06% Cu from 24.0m right below overburden sediments, including 29.4m 1.53 g/t Au and 0.11% Cu from 34.0m.

Mineralization continues at the end of hole. Drillhole DSB-63 intersected 143m grading 0.74 g/t Au and 0.10% Cu from surface, including 36.5m grading 1.25 g/t Au and 0.14% Cu from 30.0m, and 85.1m grading 0.44 g/t Au and 0.08% Cu from 165.9m. Weak mineralization continues at the end of hole.

Drillhole DSB-64 intersected 121.65m grading 0.44 g/t Au and 0.07% Cu from 20.5m right below overburden. These drill results, with
