Avanti Gold extends Akyanga system to 2.98 m at 6.20 g/t Au at depth

HIGHLIGHTS

Phase I drilling intersects gold mineralization below US$1,500/oz pit shell constraint, confirming the 3.11 Moz Akyanga gold system extends beneath the current Mineral Resource and remains open at depth

MSDD0145 returned: 4.30 m at 1.71 g/t Au from 262.40 m; and

6.80 m at 1.59 g/t Au from 276.00 m, including 0.50 m at 12.60 g/t Au from 282.30 m.

MSDD0146 returned: 20.43 m at 0.91 g/t Au from 297.92 m, including 7.00 m at 1.48 g/t Au from 311.35 m; and

a separate interval of 2.98 m at 6.20 g/t Au from 325.27 m, including 2.00 m at 9.05 g/t Au from 326.25 m.

Results support continued resource growth anticipated ahead of 2027 Preliminary Economic Assessment

Additional rigs now dedicated to site; Phase 2 program imminent, with more assay results to follow

Vancouver, British Columbia--(Newsfile Corp. - August 11, 2026) - Avanti Gold Corp. (CSE: AGC) (FSE: X370) (OTCQB: AVTGF) (" Avanti " or the " Company ") is pleased to report initial assay results from its 2026 Phase I diamond drilling program at the Akyanga Deposit, part of the Company's Misisi Gold Project in the Democratic Republic of the Congo ("DRC"). Diamond drill holes MSDD0145 and MSDD0146 intersected multiple zones of gold mineralization below the limits of the US$1,500/oz pit shell used to constrain the current Akyanga Mineral Resource Estimate. The results provide additional geological and grade information at depth and will assist the Company in refining its interpretation of the Akyanga mineralized system and planning follow-up drilling. Exploration activities are also continuing across additional priority targets within the broader Misisi Project.

Intersects from Diamond Drilling at the Akyanga Deposit include: MSDD0145

4.30 m at 1.71 g/t Au from 262.40 m; and

6.80 m at 1.59 g/t Au from 276.00 m, including 0.
