Vancouver, British Columbia — December 1, 2025 — Avanti Gold Corp. (CSE: AGC) (FSE: X370) (“Avanti” or the “Company”) is

pleased to report that it is making rapid progress to rapidly launch exploration activities in Q1-2026 at its Misisi Project, a high-

quality gold project located in the Democratic Republic of the Congo (“DRC”).

The newly appointed management team has recently completed an in-country field visit, including visits to Kinshasa,

Lubumbashi, Kalemie and the Misisi access road, where they held key meetings with suppliers, government, civil society groups,

traditional leaders, and some parties from Misisi Village.

Efforts are being focused on three parallel tracks: (1) reviewing and negotiating tenders for the 2026 Phase 1 exploration

programme, (2) establishing in-country supply chains, security measures, and community relations aided by the hiring of key

management positions, and (3) evaluating previous drilling and sampling data through a desktop review to inform the Phase 1

exploration programme. All workstreams are rapidly proceeding, with signed drilling and laboratory contracts expected in late

Q4-2025 to early Q1-2026, key hiring decisions expected in the coming weeks, and the start of exploration activities targeted in

Q1-2026.

Sir Samuel Jonah, Chairman, Avanti Gold Corp, “The Board is encouraged by the decisive progress made over the past several

weeks as Avanti re-establishes operations at Misisi. The work underway to strengthen local partnerships, secure critical

services, and mobilise for phase 1 drilling demonstrates a disciplined and execution-focused approach. We are confident that

the leadership team are positioning the Company to unlock the significant potential of the Misisi Project.”

Martin Pawlitshek, Incoming CEO of Avanti, commented: "We have just completed a successful field visit in the DRC to establish

supply chain logistics and engage with key stakeholders of the Misisi Project, having met directly with government officials, local

authorities, national and local suppliers, and community representatives across Kinshasa, Kalemie, Lubumbashi, and the Misisi

Village. An pre-mobilization team is currently at the Misisi site engage constructively with the community and lay the groundwork

for future collaboration.

The field visit confirmed a workable environment with respect to local supply chains, security measures, and community relations.

Through the visit, we were able to assess the broader site access and security conditions and to start engaging local contractors

to support the refurbishment of facilities and improvements to road access to Misisi and the Lulimba airstrip. These assessments

underpin our ongoing negotiations with drilling tenders, as we seek to secure a robust supply chain to site.

During meetings in Kalemie and Lubumbashi, we started negotiations with national and regional suppliers regarding drilling,

laboratory services, and logistics. Several tenders have now been received, and we are systematically evaluating the technical

and operational requirements to ensure we select partners who can support the programme effectively.

With a defined 3.1 million ounce Inferred Mineral Resource at a grade of 2.37 g/t gold and in-country logistics confirmed, we

have solidified a robust foundation to underpin the Misisi Project. We are well positioned to unlock significant upside value as we

progress our Phase 1 exploration programme across several identified targets on three contiguous long-term mining leases

covering 133 km² of the highly prospective Kibara Gold belt. Our focus now is on advancing the project in a disciplined manner,

supported by thorough preparation, responsible practices, and meaningful engagement with stakeholders.

We were also honoured to meet with his Excellency, Louis Watum Kabamba, Minister of Mines, which allowed us to formally

introduce our new team to the authorities and to discuss our plans to re-start operations at the project. The meeting was well

received by both parties."

The key priority for the field visit was to establish local supply chains, community relations & security plans, and define key

partnerships to accelerate the phase 1 exploration drill programme. During the visit, it was confirmed that Kalemie provides the

most logical and advanced point of entry to facilitate access to the Misisi project site for equipment and personnel given its ease

of accessibility by air, boat and road in addition to ongoing refurbishment works undertaken by other companies active in the

region. Heavy equipment, transport trucks, lowbeds, generators and containers are all readily available in sufficient quantities

in Kalemie, significantly de-risking mobilization for drilling and refurbishment efforts while drill rigs are available to be brought

to site through to Kalemie, via Lubumbashi or Tanzania.

› Road Access: Misisi is located 5km from the N5 national highway, which links the project area to Kalemie in the south by

180km of laterite highway. Ongoing refurbishment measures are currently underway at the 35Km, 80km and 135km marks

from Kalemie to Misisi, funded by tenement holders adjacent to Avanti’s mining licenses. Avanti plans to commence the

refurbishment of the 12km road access to the Lulimba airstrip to the north of site, as well as points on the road from

Kalemie, so that heavy equipment can be brought to site.

› Workforce: Management met with personnel of Avanti’s local subsidiary, LEDA Mining Congo S.A. in Kalemie, Lubumbashi

and Kinshasa, initiating the work to recommence exploration activities in Q1-2026.

› Security: Initial security assessments have been carried out across the Kalemie –Misisi–Lulimba corridor with the support

of national and local security service companies. Security personnel and consultants are engaged to finalize plans for the

start up of the operation and ongoing support which will be closely tied to working with local communities.

› Water: Water required for exploration activities, including drilling, is readily available from bore holes and surface water.

› Power: The Misisi region is not connected to the national power grid, with on -site generators required to power the

exploration camp. Nevertheless, the site is located close to ongoing national power projects, including a hydroelectric

facility in Bendera, approximately 45- kilometers to the south of the project area, and power from local grids as shown in

Figure 5 above.

Furthermore, several pre-mobilization steps required for the phase 1 exploration programme launch were progressed,

including; (1) completion of steps to obtain export permits for the historic samples at Misisi, (2) completing required surface

fee payments, and (3) conducting initial security, community, and administrative visits in the region.

Key upcoming catalysts include:

› Drilling and laboratory service contracts: announcement of signed contracts for exploration service providers for the Misisi

Project.

› Refurbishment of camp: Increase capacity of exploration camp facilities at the Misisi Village to support increased

exploration activities.

› Review of existing data: Existing data is being evaluated with the goal of optimizing the phase 1 drilling program and

priorities.

› Key appointments: Key in-country management appointments including Security & HSE, Admin & Logistics, Exploration and

Community managers

› Launch of Phase 1 exploration programme : A proposed 15,000m drill programme covering previously identified high-

priority targets.

› Assay results: Assay results from 2,100-meter of historic diamond core that targeted both the northwest extension and the

high-grade southern zones of the Akyanga deposit

ABOUT THE MISISI PROJECT AND ITS UPCOMING EXPLORATION PROGRAMME

The Misisi Gold Project is located 180km north of Kalemie and spans three contiguous 30- year mining leases covering 133km 2

along 55km of structure in the Kibara Gold Belt, a prominent metallogenic province known for hosting significant gold deposits.

Avanti owns a 73.5% interest in the Misisi Project, with the remaining minority interests held 21.5% by MMG Limited, and a 5%

free-carried interest held by the DRC government, under the 2002 Mining Code. Within the license area, a number of exploration

targets have been delineated through artisanal mining, soil and rock chip geochemistry, trenching, geophysics and limited

diamond drilling including the Akyanga, Akyanga East, Ngalula, Lubitchako, Tulonge, and Kilombwe targets.

The Misisi Project area is dominated by interbedded quartz–muscovite schists, schistose arkoses, muscovite quartzites,

quartzites, pebble conglomerates and foliated mafic intrusions. The Akyanga deposit is the primary deposit on the licenses

property, which comprises an overturned meta-sedimentary sequence intruded by dolerite and gabbro. Historical exploration

has delineated several sub-parallel mineralised zones with strike lengths of up to 2,000m. These zones, generally less than 10m

thick, dip moderately to shallowly to the southeast in the southern portion of the deposit. Toward the central and northern

sections, the mineralisation steepens, becoming near-vertical at surface in the north before flattening at depth. Mineralisation

is structurally and lithologically controlled, hosted along north–south striking deformation zones.

Phase 1 exploration programme

Following a tender process, several proposals have been received for drilling services from a diverse group of suppliers at the

local, regional and national level. Tenders for laboratory services have been received from in-country and neighbouring labs.

Avanti is currently evaluating and negotiating tenders with the expectation of signing agreements in late Q4-2025 to early Q1-

2026.

In parallel, Avanti is reviewing and re-evaluating prior exploration data, including trenching, soil samples, airborne magnetics

and drilling, to prioritize targets across the three contiguous 30-year mining licenses. The tentative drilling programme, as

outlined in Table 1 below, will prioritize footprint expansion at the Akyanga deposit, and target testing across the other high-

priority targets with a particular focus on Akyanga East, due to its close proximity to Akyanga, and at Ngalula, due to its significant

gold-in-soil anomaly results and large 8km identified strike length, of which there is an identified 3km main zone with widths up

to 600m.

Metallurgical testwork of samples from Akyanga indicates good recoveries with standard processing techniques. Cyanide bottle

roll testing on early drill core confirmed significant free-milling, coarse gold, with only minor sulphide content, yielding potential

recoveries in excess of 91% across all tested samples.

As shown in Figure 8 below, mineralisation remains open at depth below the $1,500/oz conceptual pit shell, dipping towards the

southeast towards the Akyanga East structure. Notably, historical wide-space drilling confirms strong continuity in both grade

and thickness of the mineralised package, while high-grade intercepts have been identified at depth.

Other High Priority Targets

Through 2011-2012, an extensive soil geochemical program was completed across the Misisi Project, collecting approximately

5,439 samples across the 55km strike length of the property. Initial sampling was conducted on 1km spaced lines with 50m

intervals, followed by infill sampling on 200m and 100m lines in priority areas. This work identified 16 significant soil anomalies

outside the Akyanga resource area, defined as coherent clusters of samples with gold values above 100 ppb. Only limited follow-

up exploration drilling has been completed on three of these anomalies: Akyanga East, Tulonge and Lubitchako.

1) Akyanga East

The Akyanga East Target is defined over a 5.5 -kilometer strike and situated approximately 1 -kilometer east of the Akyanga

Deposit. The mineralisation can be traced along strike for approximately 5.5 km, primarily through artisanal workings. Ten

diamond drill holes were completed on the target in 2013 with spacing between 200 and 500 meters apart. The proximity and

potential continuity with the Akyanga Deposit represent a significant upside opportunity.

Notable intercepts from the historical drilling programme including:

› MSDD0059: 5.1 meters at 8.50 g/t Au

› MSDD0064: 11.1 meters at 1.56 g/t Au and 7.9 meters at 3.30 g/t Au

› MSDD0090: 13.3 meters at 1.33 g/t Au and 1.3 meters at 4.41 g/t Au

2) Lubitchako

The Lubitchako Target is defined over a 1.2-kilometer strike and situated approximately 7-kilometers south of the Akyanga

Deposit. The target was identified through a soil sampling program, and further supported by positive trench results in a follow-

up program. Four diamond drill holes were completed on the target in 2013 encountering a series of stacked quartz veins which

warrant further exploration.
