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.

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.

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
