2025 Guidance

In 2025, Allied anticipates producing 375,000 to 400,000 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.

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, the 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 expected 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.

The following table presents expansionary capital, sustaining capital, and exploration spend expectations by mine and company-level for 2025:

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.

The following table presents other expenditure expectations for 2025:

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 developments 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 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, along 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.

CAUTIONARY NOTE TO U.S. INVESTORS REGARDING ESTIMATES OF MEASURED, INDICATED AND INFERRED RESOURCES

This press release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ in certain material respects from the disclosure requirements promulgated by the U.S. Securities and Exchange Commission (the "SEC"). For example, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are Canadian mining terms as defined in accordance with Canadian NI 43-101 and CIM Standards. These definitions differ from the definitions in the disclosure requirements promulgated by the SEC. Accordingly, information contained in this press release may not be comparable to similar information made public by U.S. companies reporting pursuant to SEC disclosure requirements.

CAUTIONARY STATEMENT REGARDING NON-GAAP MEASURES

The Company has included certain non-GAAP financial performance measures and ratios to supplement its Consolidated Financial Statements, which are presented in accordance with IFRS, including the following:

• Cash costs per gold ounce sold;

• AISC per gold ounce sold; and

The Company believes that these measures, together with measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company.

Non-GAAP financial performance measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures employed by other companies. Non-GAAP financial performance measures are intended to provide additional information, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS and are not necessarily indicative of operating costs, operating earnings or cash flows presented under IFRS.

Management's determination of the components of non-GAAP financial performance measures and other financial measures are evaluated on a periodic basis, influenced by new items and transactions, a review of investor uses and new regulations as applicable. Any changes to the measures are duly noted and retrospectively applied, as applicable. Subtotals and per unit measures may not calculate based on amounts presented in the following tables due to rounding.

The measures of cash costs and AISC, along with revenue from sales, are considered to be key indicators of a company's ability to generate operating earnings and cash flows from its mining operations.

CASH COSTS PER GOLD OUNCE SOLD

Cash costs include mine site operating costs such as mining, processing, administration, production taxes and royalties which are not based on sales or taxable income calculations. Cash costs exclude DA, exploration costs, accretion and amortization of reclamation and remediation, and capital, development and exploration spend. Cash costs include only items directly related to each mine site, and do not include any cost associated with the general corporate overhead structure.

The Company discloses cash costs because it understands that certain investors use this information to determine the Company's ability to generate earnings and cash flows for use in investing and other activities. The Company believes that conventional measures of performance prepared in accordance with IFRS do not fully illustrate the ability of its operating mines to generate cash flows. The most directly comparable IFRS measure is cost of sales, excluding DA. As aforementioned, this non-GAAP measure does not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures employed by other companies, should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS, and is not necessarily indicative of operating costs, operating earnings or cash flows presented under IFRS.

Cash costs are computed on a weighted average basis, with the aforementioned costs, net of by-product revenue credits from sales of silver, being the numerator in the calculation, divided by gold ounces sold.

AISC PER GOLD OUNCE SOLD

AISC figures are calculated generally in accordance with a standard developed by the World Gold Council ("WGC"), a non-regulatory, market development organization for the gold industry. Adoption of the standard is voluntary, and the standard is an attempt to create uniformity and a standard amongst the industry and those that adopt it. Nonetheless, the cost measures presented herein may not be comparable to other similarly titled measures of other companies. The Company is not a member of the WGC at this time.

AISC include cash costs (as defined above), mine sustaining capital expenditures (including stripping), sustaining mine-site exploration and evaluation expensed and capitalized, and accretion and amortization of reclamation and remediation. AISC exclude capital expenditures attributable to projects or mine expansions, exploration and evaluation costs attributable to growth projects, DA, income tax payments, borrowing costs and dividend payments. AISC include only items directly related to each mine site, and do not include any cost associated with the general corporate overhead structure. As a result, Total AISC represent the weighted average of the three operating mines, and not a consolidated total for the Company. Consequently, this measure is not representative of all of the Company's cash expenditures.

Sustaining capital expenditures are expenditures that do not increase annual gold ounce production at a mine site and exclude all expenditures at the Company's development projects as well as certain expenditures at the Company's operating sites that are deemed expansionary in nature, such as the Sadiola Phased Expansion, the construction and development of Kurmuk and the PB5 pushback at Bonikro. Exploration capital expenditures represent exploration spend that has met criteria for capitalization under IFRS.

The Company discloses AISC as it believes that the measure provides useful information and assists investors in understanding total sustaining expenditures of producing and selling gold from current operations, and evaluating the Company's operating performance and its ability to generate cash flow. The most directly comparable IFRS measure is cost of sales, excluding DA. As aforementioned, this non-GAAP measure does not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures employed by other companies, should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS, and is not necessarily indicative of operating costs, operating earnings or cash flows presented under IFRS.

AISC are computed on a weighted average basis, with the aforementioned costs, net of by-product revenue credits from sales of silver, being the numerator in the calculation, divided by gold ounces sold.
