Allied GOLD Announces 2025 Guidance and Near-Term Outlook

Corporate Updates

NEWS RELEASE

ALLIED GOLD ANNOUNCES 2025 GUIDANCE AND NEAR-TERM OUTLOOK

TORONTO, ON – February 20, 2025 ─ Allied Gold Corporation (TSX: AAUC, OTCQX: AAUCF)

(“Allied” or the “Company”) herein provides its 202 5 operating guidance and medium-term

outlook, including updates to Mineral Reserves and Mineral Resources.

Highlights

• The Company's producing mines are expected to produce between 375,000 and 400,000 gold

ounces per year, as evidenced by the run rate delivered in the fourth quarter of 2024 of 99,632

gold ounces, which is consistent with Allied’s previously provided guidance and outlook for

production at its producing mines. Mine-site level All-In Sustaining Costs(1) (“AISC”) for 2025

are expected to be between US$1,690 and US$1,790 per ounce , reflecting operational

improvements and the implementation of the changes to the mining code in Mali.

• At Kurmuk, earthworks and structural fills at the plant terrace are near completion, while civil

works and SMPP (structural, mechanical, plate, and piping) contractor mobilizations are in

progress. Main camp construction, along with engineering and procurement activities remain

on track and on budget. Mining activities are planned to start in the latter part of the first quarter

and continue through the year and into 2026 with the objective of preparing the mine and

building ore stockpiles to support the start of operations. Capital expenditures of US$280

million are anticipated for Kurmuk in 2025, with the remaining capital to completion and the

first gold planned for the first half of 2026. Kurmuk is expected to deliver 175,000 gold ounces

for the partial year of production in 2026, an average production level of approximately

290,000 gold ounces per annum over the first four years and 240,000 gold ounces per annum

over the life of the mine at industry-leading All-In Sustaining Costs(1) (“AISC”) costs below

US$950 per ounce.

• The first phase of expansion at Sadiola commenced in the fourth quarter of 2024 and is

advancing on schedule and on budget, with earthworks and structural fill, along with

engineering, procurement, and mobilization for mechanical contractors progressing well.

Continued investment in the first phase expansion, including planned plant modifications and

infrastructure upgrades, is consistent with prior estimates at US$70 million in 2025. The first

phase plant expansion involves installing additional crushing and grinding capacity in one of

the Sadiola’s processing lines , which will be dedicated to processing fresh ore. These

modifications will allow Sadiola to treat up to 60% of fresh rock at a rate of up to 5.7 Mt/y in

the modified process plant starting the fourth quarter of 2025. With the completion of plant

modifications in the first phase, Sadiola is expected to produce between 200,000 and 230,000

ounces of gold per year in the medium term, ahead of the next phase of expansion. This

second phase expansion is expected to be completed in late 2028 and will target a production

level of 400,000 gold ounces per annum over the first four years and 300,000 gold ounces

per annum over the life of the mine, with AISC(1) expected to decrease to below US$1,200 per

gold ounce.

2025 Guidance

In 202 5, Allied anticipates producing 375,000 to 4 00,000 ounces of gold , representing a

meaningful increase in production year-over-year. Achieving the higher end of this guided range

primarily hinges on capturing opportunities to increase oxide ore feed in Agbaou from the Hire

area, which are currently being studied.

Total Gold Production 343,817 358,090 99,632 375,000 – 400,000

Certain optimizations improved performance throughout 2024, resulting in higher production in

Q4 2024. Similarly, production in 2025 is expected to be back -half weighted, with a first-

half/second-half split of 45%/55%. Due to mine sequencing, the first quarter of 2025 production

is expected to be below the levels of the first quarters of 2023 and 2024, while production in Q4

2025 is expected to be meaningfully higher than the first three quarters of the year. This is driven

by improvements to feed grades resulting from stripping and sequencing at Bonikro and the

completion of the first phase of expansion at Sadiola in the third quarter. Production in the fourth

quarter is expected to be 56% higher than in the first quarter of 2025.

Regarding costs, the projected mine-site level AISC(1) for 2025 is expected to be US$1,690-

US$1,790 per ounce, reflecting operational improvements at Bonikro and Sadiola. At Agbaou the

Company is pursuing opportunities to increase oxide feed from exploration targets located in the

Hire area mentioned above, providing an opportunity to reduce AISC . At Sadiola, the cost

guidance reflects the implementation of the previously announced Protocol Agreement with Mali

over the entire year of operations.

Every US$100/oz increase in the price of gold is expected to result in US$15/oz higher AISC(1) on

a consolidated basis, primarily due to certain royalties based on gold price. Given the Ad-Valorem

tax at Sadiola, this gold price impact is proportionally higher. Guidance AISC(1) is defined at a gold

price of US $2,500 per ounce . Primarily due to certain royalties based on gold price, every

US$100/oz increase in the price of gold is expe cted to result in US$15/oz higher AISC(1) on a

consolidated basis with most of that attributable to Sadiola, at which the gold price impact to

AISC(1) is proportionally higher. Corporate items are expected to add approximately US$100 per

ounce sold to arrive at the corporate-level AISC(1), with this impact decreasing in future periods

as costs decline and production rises.

Bonikro will incur an anticipated US$60 million of capital expenditures related to production

stripping during 2025, further exposing higher-grade ore and leading to robust free cash flows in

the years that follow when the rock movement and stripping ratio meaningfully decreases. As the

waste stripping benefits not only 2025 but also the following two years of production, the AISC

per Ounce Sold figure accounts for the allocation of the stripping spend over the ounces it benefits

through 2027. Waste stripping at Bonikro during 2026 and 2027 is expected to be negligible.

Similarly, Agbaou will incur an anticipated US$25 million of capital expenditures related to

production stripping during 2025, which is expected to lead to improved performance in future

years.

Approximately 70% of the Company’s expected exploration spend is capital in nature.

Outlook 2026-2027

In 2025, Allied is focused on delivering increased oxide feed at Sadiola and completing the first

phase expansion, advancing construction activities at Kurmuk while also continuing its exploration

efforts to extend mine life, particularly in Côte d'Ivoire. Alongside this, the Company is dedicated

to finding operational improvements to increase production and reduce costs.

While not currently reflected in Allied's official one -year guidance, the operating trends clearly

support the Company's strategic vision of achieving significant growth at substantially lower costs

and underpin the outlook for 2026 and 2027.

At Sadiola, gold production is anticipated to increase sequentially in 2026 and 2027, with a goal

of achieving between 200,000 and 230,000 ounces of production per annum. The improvement

over the previous year's production levels is expected to be driven by the inclusion of additional

oxide ores from targets such as Sekekoto West, FE4, and FE2.5, and others, alongside the

positive impacts from treating higher-grade fresh rock as the result of the implementation of the

first phase expansion . These developmen ts are anticipated to offer further opportunities for

production increases and cost reductions.

Bonikro is expected to achieve stable gold production during the outlook period, with a goal of

averaging 100,000 ounces annually. This projection does not account for the potential additional

benefits from mining sequence optimizations, ore feed from Oume, and other exploration targets.

As previously noted, the waste stripping executed in 2024 and continuing in 2025 is expected to

expose higher-grade ore in 2025 and beyond, significantly reducing the mine-site AISC(1) to below

US$1,500 per ounce starting in 2026. At Oume, exploration and infill drilling efforts continue, with

the potential for further extensions of the mineralization areas and advanced resource drilling at

Oume West and North. The program’s objective is to increase the mineral inventories by the end

of the year in connection to the advancement of the project.

For Agbaou, gold production is expected to remain consistent each year throughout the outlook

period, not falling below 87,000 ounces annually. The improvements are attributed to the mining

sequence improvement and the identification of additional Mineral Reserves in Agbalé, as well as

operational optimizations. These enhancements enable the mill to handle relatively harder rock

blends more effectively while also offering the opportunity to increase oxide feed from Agbalé and

other targets.

Kurmuk is expected to start production by mid-2026, contributing an estimated 175,000 ounces

of gold to the latter half of the 2026 forecast. For 2027 and 2028, the mine is expected to increase

production sequentially year over year, with an average target production of approximately

265,000 ounces over that period and nearly 290,000 ounces per annum on average over the first

four years of production. Significant exploration potential at near -mine locations around Dish

Mountain and Ashashire, along with the regional Tsenge prospect and other targets, supports a

strategic mine life of at least 15 years at a mine-site AISC(1) below US$950 per ounce.

Mineral Reserves and Mineral Resources Update

Allied’s near-term guidance and longer-term outlook are supported by its Mineral Reserves and

Mineral Resources, which ensure the reliability and sustainability of the Company’s production

platform while also providing the flexibility to increase near-term production and cash flows from

high-yield near-mine targets. This year, Allied has conducted a thorough review of its mining

design parameters, leading to the adoption of more conservative assumptions, especially

regarding operational factors such as mining selectivity and dilution. This strategic adjustment

aims to improve ore control procedures and the short -term predictability of operations. It also

serves to offset the impact of increased Mineral Reserves together with the depletion resulting

from mining activities in 2024. The Company is optimistic that its exploration efforts will continue

to increase mineral inventories, with a goal to achieve additional growth by the end of 2025.

As of December 31, 2024, the Proven and Probable Mineral Reserves were reported at 10.8

million ounces of gold, contained within 237 million tonnes at a grade of 1.42 g/t. This figure

remained relatively unchanged compared to the previous year. The stable reserve balance

reflects the addition of new Mineral Reserves, the depletion of reserves due to production in 2024,

and adjustments to the economic and design parameters outlined above. Similarly, the total

Measured and Indicated Mineral Resources stood at 15.7 million ounces of gold, contained within

327 million tonnes at a grade of 1.49 g/t. This is nearly the same as the previous year's figure of

16.0 million ounces, with the slight decrease attributed to the conversion of Inferred Mineral

Resources, which at year-end 2024 totaled 1.4 million ounces contained within 33.7 million tonnes

at a grade of 1.33 g/t.

At Sadiola, the Company updated its economic parameters to reflect the new mining code in Mali,

which introduced higher royalties and operating costs. However, the impact of these increases

- 5 -

was largely offset by higher gold price assumptions. Notably, the partial inclusion of the newly

discovered oxide mineralization at Sekekoto West has been incorporated into the 2025 mine plan,

as part of it was successfully converted into Mineral Reserves. Furthermore, Sekekoto West

remains open to the north and is currently being drilled, testing for extensions of the mineralization

to realize further growth potential. Additionally, mineralization at FE2.5 remains open along strike,

with sub-parallel structures identified that could potentially reduce the stripping ratio, allowing

access to deeper mineralization. One of the key focuses for 2025 will be further defining the FE2.5

zone along strike and converting the Inferred Mineral Resources into Indicated Resources. To the

southwest of Sadiola Main, the Tambali South zone continues to show significant potential at

depth. An ongoing infill drilling program, alo ng with geotechnical and hydrogeological

investigations, is expected to convert Tambali South Mineral Resources into Mineral Reserves

during 2025 in order to integrate it into the mine new life of mine plan.

At Bonikro, the net results remained in line with expectations. Although slight reductions in Mineral

Reserves resulted from refinements to the mine design parameters, these were largely offset by

an increase in stockpiled material, which adds flexibility to the operation. During 2024, exploration

efforts at Oume successfully converted a significant amount of Inferred Mineral Resources into

Indicated Resources, with a more refined geological understanding of the mineralization and

grade distribution in support of advancing the project to its next phase of development. Moreover,

geotechnical and hydrogeological drilling programs are planned for 2025 to support a Pre -

Feasibility Study at the site. The results of this study are expected by the end of 2025.

Similar to Bonikro, design parameters at Agbaou were adjusted to improve operational efficiency

and reduce dilution. The mining sequence has been optimized to balance the intensity of waste-

stripping pushbacks. Ongoing infill drilling has confirmed the geometry, width, and grade of the

mineralized structures currently being mined at Agbaou, significantly de-risking the mine plan for

2026 and 2027.

At Kurmuk, work to refine the geological framework of the mineralization in anticipation of the start

of mining operations in the next months is ongoing. A detailed litho-structural surface map of Dish

Mountain has been generated, utilizing numerous rock exposures uncovered during construction.

This information, along with drilling being done to extend mineralization in Dish Mountain, is

currently being integrated into the three -dimensional litho -structural model. Infill drilling is

progressing well, and by Q3 2025 Allied expects an updated Mineral Resources and Mineral

Reserves statement that will further define Proven and Probable Mineral Reserves, Measured

and Indicated Mineral Resources. This update will be followed by a revised life of mine plan with

a focus on the start of operations and is targeted to de-risk the ramp -up and further improve

production levels at Kurmuk, particularly in the first years of operations. Although not expected to

be included in the Q3 2025 update, drilling at Tsenqe continues to return encouraging

intersections, and the Company anticipates declaring an initial Mineral Resource for this area in

late 2025.
