ALLIED GOLD PROVIDES UPDATE ON CONTINUED VALUE CREATION ACROSS ITS PORTFOLIO IN

PARALLEL WITH NORMAL COURSE PROGRESS WITH ZIJIN GOLD ARRANGEMENT

TORONTO, ON - June 10, 2026 — As previously announced by Allied Gold Corporation (“Allied Gold” or

the “Company”) (TSX: AAUC, NYSE: AAUC) on May 29 and Zijin Gold International Company Limited ("Zijin

Gold") on May 31, both parties remain fully committed to fulfilling the conditions for completion of the

Arrangement by the extended outside date of July 29, 2026.

In parallel, Allied has also remained focused on advancing the Company's mining assets and delivering on

its commitment to host-nation Governments and local stakeholders to advance its mine optimizations

and project development.

The Company is pleased to provide an update on mine life extension, mineral inventory growth, and

optimization initiatives across its Cote d’lvoire operations (“CDI Complex”), along with an update on the

significant development progress at the Kurmuk Gold Project in Ethiopia, and operational and growth

initiatives at the Sadiola Mine in Mali.

With respect to the CDI Complex, this update follows the maiden Mineral Reserves estimate for Oumé

announced earlier this year. As noted in the Company’s first quarter results, an updated production plan

integrating Oumé and the other mining zones around Bonikro was expected to be completed by mid-year.

This work has now been completed, confirming Oumé’s role as a meaningful contributor to the operation.

This outcome will be complemented by the anticipated update on mine life extension at Agbaou, the

result of which is expected to materially advance the Company’s objective of ten years of mine life at the

CDI Complex.

With regard to Sadiola and Kurmuk, this update reflects the progress the Company has made since early

this year, including the significant milestone of commencing pre-commissioning at Kurmuk and advancing

optimizations and further expansions at Sadiola.

These updates underscore continued execution of the Company’s strategy of enhancing its production

profile, expanding mineral inventories, strengthening cash flow generation, and advancing

transformational growth projects. Moreover, the extension of Bonikro’s mine life to 2036, continued

growth in Mineral Reserves and Mineral Resources at Agbaou, the advancement of Kurmuk toward first

gold, and ongoing optimization initiatives at Sadiola reinforce the quality, scale, and longevity of the

Company’s asset portfolio.

As Allied Gold and Zijin Gold remain committed to satisfying the conditions for completion of the

Arrangement, the Company is continuing to advance operational, optimization and growth initiatives

across the business. These achievements demonstrate both the Company portfolio's strong foundational

value and its continued potential for further growth and value appreciation.

Highlights

CDI Complex

e Integrated production plan for Bonikro extends mine life to 2036 based on the_2025 Proven and

Probable Mineral Reserves and supports average production of over 120,000 gold ounces per year,

representing a production increase of approximately 400% compared to the life-of-mine production

profile outlined in the 2023 Technical Report.

e Studies are also underway to increase Bonikro processing capacity to 3.0—3.2 Mtpa with modest

capital requirements.

e The Bonikro porphyry-style mineralization is still open to the west and below the current Mineral

Reserves with potential for the discovery of both higher-grade structures and wider lower-grade

zones.

e Agbaou Mineral Resources and Mineral Reserves updates are in progress, with both expected to

increase materially from year-end 2025.

e Ongoing near-mine exploration work is continuing to demonstrate significant potential for additional

increases to the mineral inventories and increases in mine life at Agbaou, which is expected to be

significantly extended.

e Further exploration continues to identify additional mineralization at Oumé and Ditula, among other

targets, which supports further inventory growth.

e Overall, Allied Gold has advanced its previously announced objective of increasing mine life across the

CDI Complex to at least ten years of production, with a consolidated production for the CDI Complex

projected to increase to approximately 200,000 ounces of gold per year, with Bonikro now exceeding

its target contribution to production and mine life, and Agbaou advancing toward that objective.

Kurmuk

e The project remains on schedule and on budget.

e As of the present date, overall project completion supports pre-commissioning activities, which are

now underway.

e = First gold remains expected in mid-2026.

e The project is meeting key execution milestones, and is now advancing its pre-commissioning phase,

significantly strengthening visibility on outcomes and significant value creation.

e Exploration efforts continue to advance, demonstrating extensions to the known deposits and

discovery of new mineralized areas, both of which are expected to further increase the intrinsic value

of the Kurmuk asset.

Sadiola

e Operations at Sadiola, including its supply chain, continue to progress normally and without

interruption. Consequently, the mine remains on track to meet its production guidance, with second-

quarter gold production expected to be approximately 50,000 ounces, consistent with plan.

e Processing optimization initiatives continue to advance.

e Expansion and metallurgical recovery improvement programs are progressing and are expected to

enhance operating performance and cash flow generation through a progressive, scalable approach.

e Exploration continues to discover new oxide to fresh rock mineralization while also demonstrating

depth extensions to known zones with a goal of continuing to increase Mineral Resources and to

supply new oxide feed to the mill.

CDI Complex - Mine Life Extension and Continued Inventory Growth

The CDI Complex continues to demonstrate strong operating momentum and long-term growth potential.

Following the previously disclosed increase in Mineral Reserves to approximately 1.55 million ounces of

gold as of year-end 2025 (see Allied news release dated Feb. 18, 2026), the Company has completed

updated mining planning and optimization work supporting a substantially enhanced production outlook.

This update demonstrates the Company’s significant progress on the previously announced objective of

increasing mine life across the CDI Complex to at least ten years of production, with a consolidated

production for the CDI Complex now exceeding the previous objective of 180,000 ounces per year. With

Bonikro now exceeding its target contribution to production and mine life and Agbaou advancing toward

its own objective, the strategic target production for the CDI Complex is now 200,000 gold ounces per

year for 10 years or more. A map of the CDI mining areas is available here: /ink to CDI Mining Areas.

As such, the CDI Complex now demonstrates that it delivers significantly greater value and complements

the transformational value-creation efforts at the Company’s other assets.

Select drill intercepts discussed below are presented to highlight the potential for local higher grades in

four select zones and are not necessarily representative of these deposits and zones as a whole. Collar

locations and a composite summary are available here: /ink to exploration tables.

Bonikro—Hiré—Oumé

The updated integrated production plan for Bonikro incorporates production from Hiré, Oumé, and

Bonikro and demonstrates a mine life extension to 2036 based on the 2025 Proven and Probable Mineral

Reserves, supporting average production of approximately 120,000 gold ounces per year.

The Company is completing studies to increase the Bonikro plant’s processing capacity to 3.0—3.2 million

tonnes of ore per annum. The expansion is expected to provide additional operating flexibility, support

future production opportunities, and facilitate the incorporation of additional mineral inventory from

exploration sources across the district. This increase is expected to build on the previously guided and

ongoing processing plant throughput upgrades of approximately 0.5 million tonnes of ore per annum,

intended to bring forward the processing of low-grade stockpiles at a rate of 15,000 to 20,000 gold ounces

per annum, beginning in late 2026 to early 2027.

Exploration activities continue to identify additional mineralization, supporting further inventory growth.

At Bonikro, the porphyry-style Au-Mo mineralization is still open to the west and below the current

Mineral Reserves with intercepts to 151.1 m @ 0.713 g/t Au, including 18.0 m @ 3.24 g/t Au in hole

BODD053 and 201.0 m @ 0.91 g/t Au in hole BRDD230 (assays capped at 30 g/t Au, true width unknown),

with potential for defining higher grade structures with the additional planned drilling. This type of

mineralization has been noted at the Oumé deposit, some 20 km to the north, suggesting potential for

additional discovery. At Oumé, multiple high-grade drill results (including 2.39 m @ 50.71 g/t Au in hole

DNDD127, estimated true width 1.4 m) and mineralization remain open both to depth and along strike.

Further, Oumé is expected to benefit from increased processing capacity at Bonikro, underscoring its

potential as a meaningful contributor to the Company's value creation.

Agbaou-Ditula

Agbaou Mineral Reserves updates are in progress and are expected to increase materially from year-end

2025. Ongoing exploration continues to demonstrate significant potential for additional increases in mine

life. The preliminary results of this work indicate improvements in the resource model and its underlying

data, providing a stronger foundation for ongoing updated mine optimization and design. New drill results

at Agbaou (3.96 m @ 33.43 g/t Au in hole ABDD288, estimated true width 3.2 m) both support deepening

of the pits and provide a solid rationale supporting testing for underground Mineral Resources at Agbaou

and in other areas within the CDI Complex. These also include recent drill intercepts at Hiré, Akissi So

Deposit, which returned 21.57 m @ 4.76 g/t Au in hole AKDD032 (estimated true width 15.3 m) and 1.98

m @ 33.64 g/t Au in AKRCDO65 (estimated true width 1.4 m).

These results are expected to meaningfully increase Mineral Reserves, reflecting continued successful

exploration activity, Mineral Resource conversion, and updated optimization parameters. Mine design

and planning activities are underway to support a target mine-life extension beyond 2030 while preserving

flexibility to incorporate future discoveries such as Ditula.

Ditula remains a high-priority near-mine target. Recent drilling continues to identify economic-grade

mineralization and supports the potential development of both oxide and fresh-rock Mineral Resources.

Historic results, which returned to 30 m @ 3.09 g/t Au in oxide in hole HRC2642 (true width unknown),

are being tested in the current program. Together with other satellite targets, Ditula provides a

meaningful pipeline of future growth opportunities for the Agbaou processing hub, aligned with the

updated objective of producing over 200,000 ounces of gold from the CDI Complex.

Kurmuk Development Progress

Kurmuk continues to advance well toward first production.

As of the present date, overall project completion supports pre-commissioning activities, which are now

underway.

The project is meeting key execution milestones, and it remains on budget and on schedule, and is now

advancing its pre-commissioning phase, significantly strengthening visibility on outcomes and significant

value creation. Exploration efforts continue to advance, demonstrating extensions to the known deposits

and discovery of new mineralized areas, both of which are expected to further increase the intrinsic value

of the Kurmuk asset.

Construction activities remained focused on mechanical, piping, electrical, instrumentation and control

systems. Mining activities continue to advance in support of building at least three months of ore

stockpiles ahead of start-up. The Ethiopian Electric Power Company continues to advance power line

construction, which is expected to be completed prior to commissioning.

Pre-commissioning activities began in the second quarter, with first gold expected in mid-2026.

Following start-up, Kurmuk is expected to produce an average of approximately 290,000 ounces per year

during the first four years and 240,000 ounces per year over the life of mine, with industry-leading cost

performance.

Sadiola Operations and Growth Initiatives

Operations at Sadiola, including its supply chain, continue to progress normally and without interruption.

Consequently, the mine remains on track to meet its production guidance, with second-quarter gold

production expected to be approximately 50,000 ounces, consistent with plan.

The Stage 1 grinding circuit is performing in line with design expectations, while the new crushing plant is

expected to further improve operating efficiency and reduce costs. Additional optimization initiatives,

including automation upgrades, recovery enhancement programs and installation of a pre-leach

thickener, continue to advance.

Ongoing processing-circuit optimizations include instrumentation and automation upgrades aimed at

improving recoveries and reducing costs, as well as the addition of a pre-leach thickener during 2026,

which is expected to allow the plant to process more than 90% fresh ore, increasing operational flexibility

and potentially increasing production. Together, these initiatives are expected to enhance processing

performance, improve recoveries, reduce reagent consumption, and lower operating costs. They are also

expected to establish a sustainable long-term operating platform for Sadiola at 200,000 to 230,000 ounces
