Avanti Gold Corp. (CSE: AGC) (FSE: X370) (OTCQB: AVTGF) is pleased to report additional 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.

Diamond drill holes MSDD0151, MSDD0152 and MSDD0153 intersected multiple zones of gold mineralisation within and below the US$1,500/oz pit shell used to constrain the current Akyanga Mineral Resource Estimate. Partial results from MSDD0153 also returned a significant higher-grade interval within the interpreted hanging wall of the Akyanga mineralised system.

The results provide additional geological and grade information on the distribution and geometry of mineralisation at Akyanga and will be incorporated into the Company’s evolving geological model to refine follow-up drilling. Exploration activities are also continuing across priority targets elsewhere within the broader Misisi Project.

• 5.70 m at 0.75 g/t Au from 290.60 m; and
• 5.00 m at 1.19 g/t Au from 304.70 m.

MSDD0152

• 13.60 m at 2.00 g/t Au from 86.00 m, including 0.48 m at 31.06 g/t Au from 87.70 m;

• 1.57 m at 5.23 g/t Au from 191.66 m; and
• 1.17 m at 1.68 g/t Au from 202.18 m.

MSDD0153 — Partial Results

• 4.60 m at 1.94 g/t Au from 118.00 m;
• 2.90 m at 0.50 g/t Au from 157.00 m;
• 11.50 m at 6.50 g/t Au from 166.30 m, including 1.40 m at 12.68 g/t Au from 166.30 m and 3.00 m at 11.99 g/t Au from 170.70 m; and
• 3.85 m at 0.51 g/t Au from 183.15 m.

Mohamed Cisse, Chief Executive Officer of Avanti commented: “These latest results continue to strengthen our geological understanding of the Akyanga mineralised system and demonstrate the presence of multiple gold-bearing zones across the areas currently being tested. We are particularly encouraged by the combination of width and grade returned in MSDD0153 and MSDD0151, including 11.50 metres grading 6.50 g/t Au and 5.70 metres grading 8.01 g/t Au, respectively.

“Importantly, the drilling is providing additional information both below the pit shell used to constrain the current Mineral Resource and within the interpreted hanging wall. As the Phase I program progresses, we will continue integrating these results into the geological model to refine follow-up drilling and systematically evaluate the potential for additional mineralisation 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 the commercial port of Kalemie on Lake Tanganyika . 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 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 MSDD0151, MSDD0152 and MSDD0153 totalled 981.35 metres and generated 463 samples for analysis at the SGS laboratory in Mwanza, Tanzania. Additional 150 samples from MSDD0153 (233.3 m to 385.5 m) have now been shipped to the Laboratory. The results from MSDD0151, MSDD0152 and the partial results from MSDD0153 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, 3 and 4 illustrate cross-sections through MSDD0151, MSDD0152 and MSDD0153, and show the spatial relationship between the newly reported mineralized intervals, historical drilling and the current pit-constrained Mineral Resource.

MSDD0151 intersected multiple mineralized zones over a broad downhole interval, including 5.70 m at 8.01 g/t Au from 268.10 m. MSDD0152 returned multiple intervals, including 13.60 m at 2.00 g/t Au from 86.00 m. Partial results from MSDD0153 returned 11.50 m at 6.50 g/t Au from 166.30 m within the interpreted hanging wall of the mineralized system. Together, the results provide additional information on the geometry, distribution and grade characteristics 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.
