Alamos Gold Reports First Quarter 2023 Results

Strong operational performance drives record quarterly revenues and growing cash flow from operations

TORONTO, April 26, 2023 -- Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today reported its

financial results for the quarter ended March 31, 2023.

“Following up on a strong performance in 2022, we had an excellent start to the year operationally and financially. Production

exceeded our first quarter guidance and costs were once again in line with guidance. All three operations continue to perform

well, including another standout performance from La Yaqui Grande, the key driver of our expected production growth and

decrease in costs this year,” said John A. McCluskey, President and Chief Executive Officer.

“Financially, we generated record quarterly revenues and our operating cash flow increased 16% from the fourth quarter,

marking the fourth consecutive quarterly increase. With declining costs and expanding margins over the next several years,

this is a trend we expect to continue, supporting strong free cash flow generation while completing the Phase 3+ Expansion at

Island Gold. Our growth initiatives continue to advance with the Phase 3+ Expansion on track for completion in 2026 and

having achieved a significant permitting milestone with the approval of the Environmental Impact Statement for Lynn Lake, an

important part of our longer-term growth strategy. With all of this growth coming in Canada, we remain uniquely positioned as

a growing intermediate gold producer with declining costs, increasing profitability, and one of the lowest political risk profiles in

the sector,” Mr. McCluskey added.

First Quarter 2023

• Produced 128,400 ounces of gold, exceeding quarterly guidance and marking a 30% increase from the first quarter of

2022, driven by a significant increase in production from the Mulatos District

• Mulatos District production more than doubled from the first quarter of 2022 to 50,500 ounces, at substantially lower

costs, with La Yaqui Grande driving a significant increase in mine-site free cash flow to $36.8 million

• Island Gold produced 32,900 ounces, a 34% increase from the first quarter of 2022, while continuing to make significant

progress on the Phase 3+ Expansion including the start of construction of the hoist house and other shaft infrastructure

• Young-Davidson produced 45,000 ounces and generated mine-site free cash flow 1 of $16.3 million with mining rates

averaging 8,010 tonnes per day, in line with guidance

• Sold 132,668 ounces of gold at an average realized price of $1,896 per ounce, for record quarterly revenues of $251.5

million. The average realized gold price was $6 per ounce above the London PM fix for the quarter

• Total cash costs 1 of $821 per ounce, and all-in sustaining costs ("AISC" 1) of $1,176 per ounce were 17% and 14%

lower than the first quarter of 2022, respectively, reflecting low-cost production growth from La Yaqui Grande. Total cash

costs were slightly below annual guidance, while AISC were at the top end of annual guidance, reflecting higher stock

based compensation charges resulting from the increase in the Company's share price in the period

• Realized adjusted net earnings 1 for the quarter of $45.4 million, or $0.12 per share 1. Adjusted net earnings includes

adjustments for net unrealized foreign exchange gains recorded within both deferred taxes and foreign exchange of $4.1

million, partially offset by other losses totaling $1.1 million

• Reported net earnings of $48.4 million

• Generated cash flow from operating activities of $94.3 million ($127.2 million, or $0.32 per share, before changes in

working capital 1). Working capital in the quarter was impacted by a temporary build up of sales tax receivables in

Canada, of which $20 million was collected subsequent to quarter end in April

• Free cash flow 1 of $10.5 million was impacted by the above noted delay in collecting sales tax receivables. The $20

million collected in April is expected to contribute to stronger free cash flow in the second quarter. The Company

expects to continue generating strong free cash flow over the next several years while funding the Phase 3+ Expansion

at Island Gold

• Paid a quarterly dividend of $9.8 million, or $0.025 per share (annualized rate of $0.10)

• Cash and cash equivalents increased to $133.8 million, and equity securities increased to $25.8 million. The Company

remains debt free

• Achieved a significant permitting milestone for the Lynn Lake project with a positive Decision Statement issued by the

Ministry of Environment and Climate Change Canada based on the completed Federal Environmental Impact

Statement, and Environment Act Licenses issued by the Province of Manitoba

• Reported year-end 2022 Mineral Reserves of 10.5 million ounces of gold, a 2% increase from the end of 2021 having

more than replaced mining depletion for the fourth consecutive year. Mineral Reserve grades also increased 3% driven

by higher grade additions at Island Gold and Mulatos. Additionally, Measured and Indicated Mineral Resources

increased 14% to 3.9 million ounces and Inferred Mineral Resources increased 2% to 7.1 million ounces

• Announced that the Company has entered into a definitive agreement to acquire Manitou Gold Inc., which is expected

to more than triple the regional land package adjacent to and along strike from Island Gold, adding significant

exploration potential across the Michipicoten Greenstone Belt

• Announced the appointment of Greg Fisher as Chief Financial Officer effective May 1, 2023

(3) Cost of sales includes mining and processing costs, royalties, and amortization expense, and is calculated based on the

mid-point of total cash cost guidance.

The Company’s objective is to operate a sustainable business model that can support growing returns to all stakeholders over

the long-term through growing production, expanding margins, and increasing profitability. This includes a balanced approach

to capital allocation focused on generating strong ongoing free cash flow while re-investing in high-return internal growth

opportunities and supporting higher returns to shareholders.

Following a successful 2022, the Company continues to execute operationally with production of 128,400 ounces exceeding

first quarter guidance and costs consistent with annual guidance. All three operations performed well, including another strong

quarter from Mulatos driven by low-cost production growth from La Yaqui Grande. This contributed to a solid quarter financially

with record quarterly revenues and strong ongoing free cash flow while continuing to reinvest in organic growth. Second quarter

gold production of 2023 is expected to be between 120,000 and 130,000 ounces, with costs expected to be within the annual

guidance range.

The Company continues to advance its growth initiatives supporting its strong outlook with growing production and declining

costs. The Phase 3+ Expansion at Island Gold is progressing well, with construction of the hoist house well underway and

shaft sinking on track to begin in the latter part of the year. In addition, a significant permitting milestone was achieved at the

Lynn Lake Project with the receipt of a positive Decision Statement for the Federal Environmental Impact Statement (“EIS”).

The Company also continues to add value through exploration including a 70% increase in Mineral Reserves at Puerto Del Aire

("PDA") in the Mulatos District to 728,000 ounces with grades also increasing 4%. An expanded exploration program is

underway at PDA during the first half of 2023 with excellent potential for further growth with the deposit open in multiple

directions. This growth will be incorporated into a new development plan for PDA to be completed in the fourth quarter of 2023

which is expected to outline a significant mine life extension at Mulatos.

As outlined in the three-year production and operating guidance provided in January 2023, the Company expects higher

production at significantly lower costs over the next three years. Refer to the Company’s January 12, 2023 guidance press

release for a summary of the key assumptions and related risks associated with the comprehensive 2023 guidance and three-

year production, cost and capital outlook. Production is expected to increase to between 480,000 and 520,000 ounces in

2023, a 9% increase from 2022, and remain at similar levels in 2024 and 2025. Additional upside potential exists in 2025 as

production guidance excludes the higher-grade PDA project in the Mulatos District. Company-wide AISC is expected to

decrease 4% in 2023 and 17% by 2025 to between $950 and $1,050 per ounce.

In the first quarter of 2023, Young-Davidson achieved mining rates of 8,000 tpd, in line with guidance, driving production of

45,000 ounces. Production is expected to be between 185,000 and 200,000 ounces for the year, with an increase in future

quarters driven by higher grades mined. The operation generated mine-site free cash flow of $16.3 million, slightly lower than

previous quarters, reflecting a delay in the collection of sales tax receivables.

Island Gold produced 32,900 ounces in the first quarter at total cash costs and mine-site AISC in line with annual guidance.

Island Gold is expected to produce between 120,000 and 135,000 ounces, consistent with 2022 given similar grades and

processing rates. As outlined in the Phase 3+ Expansion study released in June 2022, grades mined are expected to increase

in 2024, driving production higher. A further increase in grades and an increase in mining rates toward the latter part of 2025 is

expected to drive an increase in production and reduction in costs.

Combined gold production from the Mulatos District (including La Yaqui Grande) more than doubled from the first quarter of

2022, totaling 50,500 ounces driven by low-cost production growth at La Yaqui Grande. With the strong start to the year,

Mulatos is well positioned to meet production guidance of between 175,000 and 185,000 ounces in 2023. Total cash costs and

mine-site AISC were below annual guidance in the first quarter driven by a higher proportion of production coming from La

Yaqui Grande, but are expected to be in line with guidance for the year.

Capital spending, including capitalized exploration, of $83.8 million in the quarter was in line with annual guidance of $317

million to $357 million. The most significant spending is expected at Island Gold as the Phase 3+ Expansion ramps up, with

full year capital spending expected to be between $221 and $246 million in 2023, inclusive of capitalized exploration. Capital

spending at Island Gold is expected to remain at similar levels in 2024 and 2025 and then drop considerably in 2026 once the

expansion is complete.

The global exploration budget for 2023 is consistent with spending in 2022. The Mulatos District accounts for the largest

portion with an increased budget of $21 million, followed by $14 million at Island Gold, $8 million at Young-Davidson and $5

million at Lynn Lake. The exploration focus in 2023 will follow up on a successful year in 2022, with Mineral Reserves

increasing for the fourth consecutive year to 10.5 million ounces of gold, and grades increasing 3%.

The Company's liquidity position remains strong, ending the quarter with $133.8 million of cash and cash equivalents, $25.8

million in equity securities, and no debt. Additionally, the Company has a $500 million undrawn credit facility, providing total

liquidity of $633.8 million. As part of a balanced approach to growth and capital allocation, the current focus of growth capital

is the Phase 3+ Expansion at Island Gold. With no significant capital expected to be spent on developing Lynn Lake until the

Phase 3+ Expansion is well underway, the Company remains well positioned to fund this growth internally while generating

strong free cash flow over the next several years. The Company expects a further increase in free cash flow in 2026 with the

completion of the Phase 3+ Expansion.

Young-Davidson produced 45,000 ounces of gold in the first quarter, lower than the prior year period reflecting both lower

tonnes and grades processed.

Underground mining rates were in line with guidance, averaging 8,010 tpd in the first quarter. Grades mined averaged 2.22 g/t

Au in the first quarter, consistent with annual guidance of between 2.15 and 2.35 g/t Au. Grades mined are expected to remain

at similar levels in the second quarter, and increase through the second half of the year.

Mill throughput averaged 7,799 tpd in the first quarter with grades processed averaging 2.22 g/t Au. Tonnes milled were lower

than mined as planned, given a scheduled liner change in January. With mining rates exceeding milling rates during the

quarter, surface stockpiles increased and will be processed throughout the remainder of the year. Mill recoveries averaged

90% in the quarter, in line with guidance and the prior year period.

Financial Review

First quarter revenues of $86.3 million were 11% lower than the prior year period reflecting less ounces sold, partially offset by

a higher realized gold price.

Cost of sales (which includes mining and processing costs, royalties, and amortization expense) of $61.9 million in the first

quarter were consistent with the prior year period, due to less ounces sold offset by higher unit mining and milling costs.

Underground unit mining costs were CAD $52 per tonne in the quarter, in line with budget and higher than the prior year period

reflecting cost inflation. Inflationary pressures on mining and milling costs have been in line with expectations and incorporated

into 2023 cost guidance.

Total cash costs of $941 per ounce in the first quarter were towards the higher end of guidance due to mine sequencing with

lower grades mined. Grades mined are expected to increase in the second half of the year driving total cash costs lower. Total

cash costs were 12% higher than the prior year period reflecting the higher unit mining costs and lower grades processed,

partially offset by the weaker Canadian dollar. Mine-site AISC of $1,233 per ounce in the first quarter were 18% higher than the

prior year period, consistent with the increase in total cash costs, and slightly higher than guidance due to lower grades

mined.

Capital expenditures in the quarter included $13.2 million of sustaining capital and $2.8 million of growth capital. In addition,

$1.4 million was invested in capitalized exploration in the quarter.

Young-Davidson continues to consistently generate strong free cash flow, including mine-site free cash flow of $16.3 million in

the first quarter of 2023. Mine-site free cash flow in the quarter was impacted by a temporary build up of $8 million of sales tax

receivables for Young-Davidson which were collected in April and will benefit the second quarter. Young-Davidson has

generated over $100 million in mine-site free cash flow in each of the past two years. Young-Davidson is well positioned to

generate similar free cash flow in 2023 and over the long-term, with a 15 year Mineral Reserve life.

(5) Includes capital advances of $1.4 million for the three months ended March 31, 2022.

Island Gold produced 32,900 ounces in the first quarter of 2023, a 34% improvement from the prior year period reflecting higher

grades mined and tonnes processed.

Underground mining rates averaged 1,204 tpd in the first quarter, in line with annual guidance and higher than the prior year

period. Grades mined averaged 9.56 g/t Au in the quarter, consistent with annual guidance.

Mill throughput averaged 1,195 tpd, consistent with annual guidance, and 7% higher than the prior year period. Mill recoveries

averaged 97% in the quarter, slightly above the prior year period.

Financial Review

Island Gold generated revenues of $63.9 million in the first quarter, 46% higher than the prior year period, driven by more

ounces sold and a higher realized gold price.

Cost of sales (includes mining and processing costs, royalties and amortization expense) of $30.9 million in the first quarter

were 28% higher than the prior year period, reflecting more tonnes processed and higher mining and processing costs,

partially offset by a weaker Canadian dollar. Inflationary pressures on mining and milling costs have been in line with

expectations.

Total cash costs of $629 per ounce in the first quarter were in line with annual guidance, and lower than the prior year period,

primarily due to 18% higher grades processed and a weaker Canadian dollar. Mine-site AISC of $970 per ounce were also in

line with guidance and lower than the prior year period.

Total capital expenditures were $57.0 million in the first quarter, including $2.4 million of capitalized exploration. Spending on

the Phase 3+ Expansion continued through the first quarter with construction activities focused on shaft site surface

preparation and erection of the hoist house. In addition, capital spending was focused on lateral development and other surface

infrastructure.

Mine-site free cash flow was negative $20.5 million in the first quarter given higher capital spending related to the Phase 3+

Expansion. Mine-site free cash flow at Island Gold was also impacted by a temporary build up of $11 million of sales tax

receivables, which were collected in April and will benefit the second quarter. At current gold prices, Island Gold is expected to

largely self-finance the Phase 3+ Expansion capital over the next three years. The operation is expected to generate

significant free cash flow from 2026 onward with the completion of the expansion.
