Vancouver, British Columbia--(Newsfile Corp. - April 23, 2026) - Avanti Gold Corp. (CSE: AGC) (FSE: X370) (OTCQB: AVTGF) ("Avanti" or the "Company") is pleased to announce that it has commenced drilling activities at its flagship Misisi Gold Project in the Democratic Republic of Congo ("DRC").

Two diamond drill rigs are currently active on site (See Figure 1) with activities set to further ramp-up as two additional rigs expected to be mobilized in the coming weeks. The drill programme is expected to total 42,000-metre of drilling and is designed to grow the current resource base while systematically testing targets across the 55-kilometre Kibara Gold Belt, where the Akyanga deposit already hosts an NI 43-101 compliant Inferred Mineral Resource of 40.8 million tonnes at 2.37 g/t gold containing 3.1 million ounces. At least 6 high priority targets are expected to be drill tested. Results will be reported on an ongoing basis throughout 2026.

Mohamed Cisse, Chief Executive Officer of Avanti, commented: "Misisi is one of DRC'S most compelling undeveloped gold systems, located on a highly prospective and largely unexplored 55-kilometre belt, and we are thrilled to have relaunched drilling after nearly a decade without significant activity.

Phase 1 focuses on expanding and upgrading the existing resource, while Phase 2 introduces multiple new targets across the broader Misisi belt that have not been previously drilled. With four rigs operational in the coming weeks and 42,000 metres planned across two phases, this is the most significant exploration campaign in the Company's history and the first step in defining the broader scale of the Misisi system."

ABOUT THE MISISI PROJECT
The Misisi Project site is located in the Fizi territory of South Kivu province, in the DRC, approximately 250 kilometres south of Bukavu and 180 kilometres north of Kalemie. The project comprises three contiguous 30-year mining leases covering 133 square kilometres along the 55-kilometre Kibara Gold Belt.

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 meters of historic drilling, including 105 diamond drillholes ("DD") totalling 19,070 meters and six reverse circulation ("RC") drillholes totalling 887 meters. The resource extends from surface to a vertical depth of 350 metres over a strike length of approximately 2,100 metres, using a $1,500/oz pit shell. The mineralisation remains open at depth and along strike.

The 2026 exploration program comprises approximately 42,000 metres of diamond and RC drilling across two phases, as outlined in Table 1 below.

Table 1: 2026 Misisi Project Drilling Programme - meterage by target

Phase 1 targets approximately 15,000 meters of diamond and reverse circulation drilling at Akyanga and Akyanga East. The programme prioritizes an increased footprint expansion at Akyanga and high-priority target testing at Akyanga East, which is located 500 metres east of the main deposit and has returned historic intercepts with grades consistent with the high-grade core of Akyanga. Ground truthing, sampling, and mapping on the four Phase 2 targets- Ngalula, Tulonge, Lubitchako and Kilombwe, will be conducted concurrently to optimize Phase 2 drill targeting.

Phase 2, expected to commence in Q3 2026, will include approximately 27,000 metres of drilling across those four additional targets along the broader Misisi belt, while continuing to test extensions at Akyanga and introducing drilling onto the high priority targets. The phased approach allows for systematic target development while ramping up drilling capacity across the broader belt.

NEXT STEPS
A number of activities are currently underway to support sustained exploration activities, as described below. Our focus is on maintaining the highest standards of safety and performance as drilling is underway.

• Geological Logging & Sampling Workflow: a team of geologists have been mobilized to site, and will conduct core logging (lithology, structure, alteration) and sampling and QA/QC protocols.
• Stakeholder & Community Engagement: Maintain communication with local communities and authorities.
• Mobilization of two additional drill rigs to Misisi: The drilling contractor is in the process of mobilizing two additional drilling rigs to site, expected to arrive in Kalemie in the coming weeks
• Site Preparation for Additional Rigs: While the first two rigs are operating, preparation for the incoming rigs will include:
  • Construction of additional drill pads
  • Ensuring access roads are ready
  • Expansion of water and fuel storage
  • Scaling up camp capacity and workforce
