Discovery Mining Reports Positive Drill Results At Key Growth Projects and Provides Resource Estimates for Dome and Tvz
Discovery Mining Ltd. reported results from ongoing exploration at the Company’s advanced stage growth projects, Dome, TVZ and Owl Creek. The results, which include assays from a combined total of 55 holes (17,845.5 m) completed between Fourth Quarter 2025 and Second Quarter 2026, continued to expand mineralization, indicated excellent correlation of widths and grades to previous drilling and clearly demonstrated the upside that exists at all three projects. 9.09 gpt over 17.3m including 14.76 gpt over 7.8m, 3.86 gpt over 18.0m including 15.39 gpt over 2.6m, 13.49 gpt over 3.5m, 1.03 gpt over 17.8m, 4.89 gpt over 2.8m, 2.26 gpt over 4.2m; 5.04 gpt over 8.4m, 11.20 gpt over 3.0m; 0.79 gpt over 11.9m; 1.72 gpt over 7.0m, 0.76 gpt over 10.8m; 0.79 gpt over 6.0m, 3.26 gpt over 4.1m; 1.89 gpt over 12.1m; 1.48 gpt over 12.0m; 1.38 gpt over 17.0m; 1.61 gpt over 16.0m; 22.0 gpt over 1.0m; and 278.48 gpt over 1.1m. New intersections indicate strong correlation of mineralized zones and grades with previously drilled holes as well as potential grade upside: Samples shipped for Metallurgical testing; Initial National Instrument 43-101 (“NI 43-101”) Resource estimate expected before year end. 1210 Level: 5.13 gpt over 18.2m; 7.04 gpt over 16.9m; 5.17 gpt over 21.0m; 5.73 gpt over 23.2m; 6.93gpt over 11.7m; 5.65 gpt over 30.5m; 9.05 gpt over 13.2m and; 4.40 gpt over 14.0m, including 7.03 gpt over 6.8m; 5.24 gpt over 12.9m; and 5.46 gpt over 12.5m; 4.59 gpt over 25.0m; 4.54 gpt over 18.4m. 1680 Level: 4.51 gpt over 9.0 m; 4.30 gpt over 24.4m, including 5.73 gpt over 12.4m.

All assays are reported uncut. Intervals are reported using core lengths only as true widths are not known at this time. In this news release, “gpt” refers to grams per tonne, and “m” refer to metres. The current mineral resource at Dome includes 222,300,000 tonnes with an average grade of 1.49 gpt for a total of 11,000,000 ounces in the Inferred category. The resource assumes a large-scale, open-pit concept to expand the historic pit along strike and to depth. Significant results include: 1.89 gpt over 12.1m, in hole DOM26-033; 1.48 gpt over 12.0m, in DOM26-030; 1.38 gpt over 17.0m, in hole DOM26-034; 0.79 gpt over 11.9m, in hole DOM26-024; and 1.72 gpt over 7.0m, 0.76 gpt over 10.8m; 0.79 gpt over 6.0m and, 3.26 gpt over 4.1m, in hole DOM26-026. Drilling in the north portion of the property included 8 holes (4,349 m) to evaluate the mineralization below the north wall of the resource pit and was also very successful. Significant results include 9.09 gpt over 17.3m including 14.76 gpt over 7.8m, 3.86 gpt over 18.0m including 15.39 gpt over 2.6m, 13.49 gpt over 3.5m in hole DOM26-050; 1.03 gpt over 17.8m, 4.89 gpt over 2.8m and, 2.26 gpt over 4.2m, in hole DOM26-006A; 1.61 gpt over 13.2m and 22.0 gpt over 1.0m in hole DOM26-011; 3.04 gpt over 2.0m in hole DOM26-015; 1.51 gpt over 3.8m in hole DOM26-016 and; 5.04 gpt over 8.4m, including 11.20 gpt over 3.0m, in hole DOM26-008. Drilling to the northeast included one new hole (495 m) which tested near the northeast limit of the resource pit and intersected a quartz vein structure containing 278.48 gpt over 1.1m, including 951.0 gpt over 0.3m. Drilling at the project is continuing with two drills, one located in the southwest portion of the historic open pit and the other on the north side. Work is also continuing to evaluate additional drill targets to the north, south and west sides of the pit. Considering results and progress to date, the project remains on track for the planned resource update in late 2026. Selected intervals from these holes have been sampled and submitted to XPS Laboratories in Sudbury, Ontario, for metallurgical testing. Results are expected late 2026. Significant results from holes drilled near the 1210 level include: 5.13 gpt over 18.2m and 5.15gpt over 12.0m, in hole 27967; 7.04 gpt over 16.9m, in hole 27970; 5.17 gpt over 21.0m, in hole 27971; 5.73 gpt over 23.2m, in hole 27972; 6.93gpt over 11.7m and 4.54 gpt over 22.9m, in hole 27974; 5.65 gpt over 30.5m, including 9.05 gpt over 13.2m, in hole 27976; and 4.40 gpt over 14.0m, in hole 27977. Significant results from holes above the level include: 5.84 gpt over 10.6m, in hole 27889 and 5.13 gpt over 5.3m, in hole 27888 and significant results from below the level include: 5.24 gpt over 12.9m, in hole 27891; 3.45 gpt over 15.0m and 4.59 gpt over 25.0m in hole 27969; 2.73 gpt over 19.9m and 4.54 gpt over 18.4m in hole 27968; 3.06 gpt over 15.1m and 6.80gpt over 8.0m in hole 27894; 4.41 gpt over 13.4m in hole 27890 and 5.46 gpt over 12.5m and 4.43 gpt over 4.4m, in hole 27892. Review of results indicates good correlation of mineralized zones and grades within the new holes and previously drilled holes with local upsides in grade noted due to unsampled core in older holes. Drilling from the 1680 level includes 2 holes (720.5 m) to continue testing the lower part of the target model which also obtained very favourable results including: 4.51 gpt over 9.0 m, in hole 27849 and; 4.30 gpt over 24.4m, including 5.73 gpt over 12.4m, in hole 27899. The Owl Creek open pit is located approximately 1.5 kilometres west of the Hoyle Pond Ramp Portal and along the south side of the Hoyle Pond belt near the contact between metasedimentary and metavolcanic rocks. The pit, as well as two underground ramps below it, were developed by Falconbridge Gold in the 1980's and were utilized to recover approximately 237,000 ounces of gold at an average grade of 3.75 gpt. Significant results include: 7.09 gpt over 17.0m, including 23.12 gpt over 3.9, in hole OC26-036B; 6.35gpt over 9.4m, 2.69 gpt over 30.9m, including 9.31 gpt over 2.0m and, 2.86 gpt over 17.4m, in hole OC26-038; 3.41 gpt over 17.0m, including 7.45 gpt over 3.1m;5.96 gpt over 7.0m in hole OC27-042; 5.73 gpt over 4.2m and 2.74 gpt over 30.4m in hole OC26-046; 4.72 gpt over 24.0m, including 12.26 gpt over 6.8m, in hole OC26-040; 4.86 gpt over 8.4m in hole OC26-044; and 19.35 gpt over 5.4m, including 270.0 gpt over 0.3m in hole OC26-045A.
