Hannan Stavträsk drills 27.8 g/t Au over 0.6 m and 1.3 g/t Au over 9.2 m across 650 m strike

Hannan Stavaträsk Maiden Drilling Hits Gold in Every Hole Across 650 m Strike; High-Grade 0.6 m at 27.8 g/t Au and Broader Target of 9.2 m at 1.3 g/t Au Confirm Large-Scale System; IP Geophysics Next

Vancouver, British Columbia--(Newsfile Corp. - August 13, 2026) - Hannan Metals Limited (TSXV: HAN) (OTC Pink: HANNF) ("Hannan" or the "Company") announces the first assay results from its maiden diamond drill program at the Stavaträsk gold project in the Skellefteå district of northern Sweden (Figure 1). The program comprised seven holes for a total of 1,040 m drilled over a strike length of 650 m that is located within a 7 km trend. Results from the first 5 drillholes are reported here (ST2601-ST2605; refer to Tables 1-3 herein), while assay results for the final two holes (ST2606 and ST2607) remain pending.

Gold mineralization was intersected in all drillholes reported here (ST2601 - ST2605). Highlights so far include 9.2 m at 1.3 g/t Au (including 0.4 m at 5.6 g/t Au ) and 1.1 m at 15.6 g/t Au (including 0.6 m at 27.8 g/t Au ). In addition, a poly-metallic sample in hole ST2601 returned 0.5 m @ 8.9 g/t Au, 47.5 g/t Ag and 0.74% Cu.

Key Points:

The drill program comprised seven holes for a total of 1,040 m drilled over a strike length of 650 m.

Results reported are from the first five holes (ST2601–ST2605), with assays for the final two holes pending. Gold mineralization was intersected in every hole released.

Best drill intercepts in each hole (0.5 g/t Au cut-off, maximum 2 m internal dilution; higher-grade sub-intervals reported at a 3.0 g/t Au cut-off) are as follows: ST2601: 4.5 m @ 1.4 g/t Au, 8.2 g/t Ag from 80.0 m, including:

0.5 m @ 8.9 g/t Au, 47.5 g/t Ag

ST2602: 5.6 m @ 1.4 g/t Au, 1.3 g/t Ag from 79.4 m, including: 0.4 m @ 9.9 g/t Au, 4.4 g/t Ag

ST2603: 1.3 m @ 2.6 g/t Au, 1.9 g/t Ag from 12.0 m

ST2604: 9.2 m @ 1.3 g/t Au, 0.7 g/t Ag from 29.9 m, including: 1.0 m @ 3.7 g/t Au , 2.0 g/t Ag

0.8 m @ 5.0 g/t A u, 1.8 g/t Ag

ST2605: 1.
