Auro Metals Inc. (TSX-V: AURO) (OTC Pink: AURFF)  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 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 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 grading 0.64 grams per tonne gold and 0.10% copper 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 provided in Table 2, and a drill plan view is shown in Figure 1.

“This second batch of drill assay results from our Phase I Drill Program at Santa Barbara South continue to highlight the scale and consistency of the Project,” said Victor Feng, CEO of Auro. “DSB-59 intersected 625 metres of continuous gold-copper mineralization starting from near surface and ended in mineralization at depth. The gold grade from this hole is roughly 23% higher than the gold grade of the inferred resource from our Mineral Resource Estimate. DSB-57 and DSB-58 both confirm that mineralization remains open in the up-dip direction towards surface. To date, geochemical analysis of 6 holes has been completed, 10 holes are pending assays and the 4 rigs on site continue turning. We look forward to sharing assay results when they become available.”

Notes:

1. Drill location, altitude, azimuth, and dip of drill holes are provided in Table 2.
2. Drill intercept is core length, and grade is length weighted. True width of mineralization is unknown.
3. A cut-off of 0.2 g/t Au is applied for calculation of drill intercept.
4. Calculation of gold equivalent (“AuEq”) is defined as AuEq (g/t) = Au (g/t) + Cu (%) x 0.259, based on a gold price of US$3,200/oz, and copper price of US$12,000/t metal, assuming average processing recoveries of 85.5% Au and 19.6% Cu.

DESCRIPTION OF HOLES

Hole DSB-57 was drilled to a depth of 315.7m to test the up-dip extension of the mineralized zone intercepted by historical holes DSB-23 and DSB-33A at the southern portion of Santa Barbara South, and intersected 59m (from 0.00m to 59m) grading 0.67 g/t Au and 0.10% Cu, and 37.5m (from 92.5m to 130.0m) grading 0.50 g/t Au, 0.10% Cu. Drill results from this hole indicate gold-copper mineralization is open in the up-dip direction to surface (Figure 2).

Lithology in the upper half of the hole is aphanitic basaltic andesite which is cut by quartz-hematite veining associated with potassic, chlorite and epidote alteration in patches and along fractures (Figure 3). Mineralization is characterized by pyrite and chalcopyrite in fine dissemination and narrow veinlets. The low portion until the end of the hole is dominated by volcano-sediments with disseminated primary pyrite and local patchy epidote and jasperoid alteration cut by calcite veining, but generally lacks potassic alteration and chalcopyrite. Between the mineralized basaltic andesite and unmineralized volcano-sediment sequence is interpreted to be a roughly north-south striking subvertical fault.

Hole DSB-58 was drilled to a depth of 274.80m to test the up-dip extension of the mineralized zone intercepted by the historical hole DSB-34 at the north end of Santa Barbara South, and intersected 130m (from 12.0m to 142m) grading 0.60 g/t Au and 0.09% Cu. Drill results from this hole indicate gold-copper mineralization is open in the up-dip direction to surface (Figure 4).

Lithology in the upper portion of the hole is dominated by dark aphanitic basaltic andesite sporadically cut by narrow lighter color post-mineralization andesite dykes. From surface to a depth of 12m is overburden sediments. Basaltic andesite extends from a depth of 12m throughout to a depth of 142m and is contacted by porphyritic diorite intrusion which continues to the end of the hole at a depth of 274.80m. Gold-copper mineralization occurs in the upper portion of dark basaltic andesite, characterized by quartz veining (Figure 5) with pyrite and chalcopyrite in forms of both dissemination and veinlets in surrounding basaltic andesite, usually with patchy secondary biotite (potassic alteration). In the lower diorite intrusion pyrite is identified as dissemination and narrow veinlets, but the amount of chalcopyrite is much less than in the upper basaltic andesite, which well explains the generally barren nature.

Hole DSB-59 was drilled in the approximately central area of Santa Barbara South from the top of the western hilltop in an easterly dipping direction to test the up-dip and down-dip extension of the mineralized zone intercepted by historical hole DSB-21 and intercepted 625.12m (from 81.43m to 706.55m at the end of hole) grading 0.64 g/t Au and 0.10% Cu. This hole terminated in mineralization due to drilling difficulties (Figure 6).

Lithology of the first 84 metres from surface is conglomerate and fine volcano-sediment with disturbed laminations. From 84m to 505m is dominated by dark basaltic andesite sporadically cut by dykes of andesite and diorite. Between the shallow sediments and the basaltic andesite is interpreted to be a fault. The basaltic andesite generally mineralized, cut by quartz and quartz-hematite veining (Figure 7), associated with alteration of potassic, chlorite and epidote. From 505m depth to the end of hole at 706.55m depth is porphyritic diorite with pervasive sericitic alteration plus local patchy potassic alteration and cut by numerous quartz veining, with mineralization of pyrite and chalcopyrite in forms of both dissemination and narrow veinlets (Figure 8). Hole DSB-59 is very important as it signifies that diorite intrusion is also an important host to mineralization in addition to the basaltic andesite. However, the extent of mineralization in the diorite intrusion remains unknown as the hole is terminated in mineralization due to drilling difficulties.
