Avanti Gold Grows Footprint of Akyanga Deposit with Multiple High-Grade Intersects Including 3.85 m at 12.30 g/t Au and 3.55 m at 7.73 g/t Au

HIGHLIGHTS

• Ongoing 2026 Phase 1 drilling at the Akyanga Deposit continues to intersect multiple zones of gold mineralization within and below the US$1,500/oz pit shell used to constrain the current Mineral Resource Estimate.

• MSDD0147 returned multiple higher-grade intervals, including:

• 3.55 m at 7.73 g/t Au from 170.15 m; including 2.10 m at 12.50 g/t Au from 170.60 m;
• 3.85 m at 12.30 g/t Au from 274.7 m; Including 2.85 at 16.58 g/t Au from 274.70 m;
• 2.84 m at 6.12 g/t Au from 288.23 m; Including 0.97 m at 15.35 g/t Au from 288.23 m; and
• 1.10 m at 17.58 g/t Au from 320.70 m.

• MSDD0150 returned:

• 6.00 m at 1.04 g/t Au from 109.00 m;
• 3.00 m at 5.38 g/t Au from 184.00 m, Including 0.90 m at 12.22 g/t Au from 184.00 m; and
• 5.40 m at 1.81 g/t Au from 189.85 m, Including 0.85 m at 5.39 g/t Au from 189.85 m

• The results provide additional geological and grade information across the Akyanga mineralized system and support continued follow-up drilling aimed at testing mineralization within and below the current pit-constrained Mineral Resource.

Vancouver, British Columbia–(Newsfile Corp. – August 26, 2026) – Avanti Gold Corp. (CSE: AGC) (FSE: X370) (OTCQB: AVTGF) (“Avanti” or the “Company“) is pleased to announce additional assay results from its 2026 Phase 1 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 MSDD0147 and MSDD0150 intersected multiple zones of gold mineralization within and below the limits of the US$1,500/oz pit shell used to constrain the current Akyanga Mineral Resource Estimate. The results include several higher-grade intervals and provide additional geological and grade information to support the Company’s interpretation of the Akyanga mineralized system and planning of follow-up drilling. Exploration activities continue across additional priority targets within the broader Misisi Project.

Selected drill intersections from diamond drill holes MSDD0147 and MSDD0150 are further detailed in Table 1 and include:

• MSDD0147

• 4.40 m at 1.37 g/t Au from 140.00 m;

Mohamed Cisse, Chief Executive Officer of Avanti commented: “These latest results continue to build our understanding of the Akyanga mineralized system and include several encouraging higher-grade intervals across multiple zones. Hole MSDD0147 is particularly notable, with multiple mineralized intervals encountered over a substantial vertical extent, including 3.85 metres grading 12.30 g/t Au and 3.55 metres grading 7.73 g/t Au. Our Phase I program is designed to systematically test mineralization both within and below the pit shell used to constrain the current Mineral Resource Estimate. As drilling progresses, these results will be incorporated into our geological interpretation to refine follow-up targets and evaluate the potential for additional mineralization at Akyanga.”

QUALITY CONTROL AND QUALITY ASSURANCE

Drill core was sampled at intervals of up to one metre and cut longitudinally using a diamond saw. One-half of the core was retained for reference, while the other half was placed in sealed sample bags under the supervision of Company geologists and transported to the independent SGS laboratory in Mwanza, Tanzania. Samples were crushed to 80% passing 2 mm, after which a split of up to 1.5 kg was pulverized to 90% passing 75 microns. Gold analysis was completed by fire assay using a 50-gram aliquot. Screen fire assays were used as check assays for selected high-grade samples. As part of the Company’s QA/QC program, certified reference materials, blanks and duplicates were inserted into the sample stream prior to submission to SGS.

ABOUT THE AKYANGA DEPOSIT
The Misisi Project site is located in the Fizi territory of South Kivu province, in the DRC, approximately 250 kilometers south of Bukavu and 180 kilometers north of Kalemie. The Akyanga Deposit, located centrally in the Misisi Project, hosts an NI 43-101 compliant Inferred Mineral Resource of 40.8 million tonnes averaging 2.37 g/t gold containing 3.11 million ounces which was based on 19,956 metres of historic drilling, including 105 diamond drillholes (“DD”) totalling 19,070 meters and six reverse circulation (“RC”) drillholes totalling 887 meters. The Akyanga resource is determined from surface to a vertical depth of 350 meters over a strike length of 2,100 metres, using a US$1,500/oz pit shell. The mineralisation remains open at depth and along strike.

As shown in Figure 1, drill holes MSDD0147 and MSDD0150 totalled 620.4 metres and generated 383 samples for analysis at the SGS laboratory in Mwanza, Tanzania. The results provide additional geological and grade information within and below the US$1,500/oz pit shell used to constrain the current Mineral Resource Estimate and support continued testing of the Akyanga mineralized system at depth.

Figures 2 and 3 illustrate cross-sections through MSDD0147 and MSDD0150 and show the spatial relationship between the reported mineralized intervals, previously drilled holes and the current pit-constrained Mineral Resource.
MSDD0147 intersected multiple mineralized zones over a broad downhole interval, including several higher-grade intersections between approximately 170 metres and 321 metres downhole. MSDD0150 also returned multiple mineralized intervals, including 3.00 metres at 5.38 g/t Au from 184.00 metres. Together, the results provide additional information on the distribution and geometry of mineralization in these sections of the Akyanga Deposit and will inform follow-up drilling.

¹Intercepts are reported as downhole lengths. True widths are estimated to be approximately 85% of reported downhole lengths based on current geological interpretation. Grades are calculated as length-weighted averages of uncut assay results.

GEOLOGY AND MINERALISATION
The geology of the Misisi project area is dominated by Proterozoic meta-sediments comprising interbedded quartz muscovite schists, schistose arkoses, muscovite quartzites, and quartzites; pebble conglomerates and foliated mafic intrusion. Gold mineralisation is associated with numerous zones of stacked quartz veins that occur sub-parallel to bedding. The mineralised zones have strike lengths of up to 2,000 m and are generally less than 10 m thick. At the southern end of the Akyanga deposit the vein zones dip moderate to shallowly to the southeast. In the central and northern part, the deposit steepens at surface, such that at the northern end the mineralisation is near vertical at surface and flattening out down dip. The depth of weathering is estimated to be approximately 30 m. Mineralisation is structurally and lithologically controlled, in association with local deformation zones, and occurs along north-south striking structures. The current interpretation is that the base of a mafic unit provides a contact with hardness contrast along which there has been structural movement.

ACCELERATED EXPLORATION STRATEGY
The Company has adopted a phased exploration strategy designed to maximize drilling productivity while rapidly advancing resource growth.

• Expand the existing resource footprint;
• Upgrade confidence in the current resource;
• Test extensions of known mineralization; and
• Generate geological data to support future resource growth.

UPCOMING NEWS FLOW
The Company expects a strong pipeline of exploration milestones over the coming months, including:

• Commencement of Phase 2 drilling
• Ongoing drill assay releases;
• Resource growth drilling of the Akyanga mineral resource; and
• Continued advancement toward future resource updates and initial drilling results from regional exploration targets across the Misisi Project and technical studies leading to the upcoming PEA study.
