Alamos Gold Announces Completion of Construction and Initial Production at

La Yaqui Grande

Toronto, Ontario (June 20, 2022) – Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or

the “Company”) is pleased to announce initial gold production from the La Yaqui Grande mine,

following the completion of construction this month, ahead of schedule. Stacking rates

continue to ramp up with leaching activities beginning earlier in June.

To mark the occasion, the Company held a ceremony at site with President and Chief

Executive Officer John A. McCluskey, members of the Alamos Gold Board of Directors, and

employees from the La Yaqui Grande mine.

“This represents a significant achievement with construction of La Yaqui Grande having been

completed ahead of schedule while navigating a challenging environment over the past few

years with COVID-19. On behalf of Alamos, I would like to congratulate our entire team at

Mulatos. La Yaqui Grande represents another in a long line of discoveries that have continued

to extend the mine life of the overall Mulatos Complex since it began producing in 2005. Given

its higher grades and recoveries, La Yaqui Grande underpins a strong outlook for Mulatos with

higher production and lower costs driving growing free cash flow in the second half of this year

and beyond,” said Mr. McCluskey.

A total of 991 ounces of gold were produced from the initial pour. La Yaqui Grande is

expected to produce approximately 3,000 ounces in June which is already factored into

second quarter consolidated production guidance of between 100,000 and 110,000 ounces of

gold. Consistent with full year 2022 guidance, stacking rates at La Yaqui Grande are expected

to ramp up through the second half of the year driving production higher and costs lower at

Mulatos and company-wide starting in the third quarter. Combined with lower capital spending

with construction of La Yaqui Grande completed, Mulatos is expected to generate strong

mine-site free cash flow starting in the second half of the year. Costs are expected to continue

to improve into 2023 reflecting a full year of production from La Yaqui Grande.

First announced in July 2020 as Alamos Gold’s next low-cost, high-return project in the

Mulatos District, this large-scale construction project will extend the life of mine for at least five

years thus sustaining the Company’s presence and importance in the production of gold in the

state of Sonora, Mexico. La Yaqui Grande was completed ahead of schedule generating more

than 1,000 jobs during the construction phase and will continue to sustain 450 direct jobs.

Cautionary Note to U.S. Investors

Alamos prepares its disclosure in accordance with the requirements of securities laws in effect in Canada. Unless

otherwise indicated, all Mineral Resource and Mineral Reserve estimates included in this document have been

prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”)

and the Canadian Institute of Mining, Me tallurgy and Petroleum (the “CIM”) - CIM Definition Standards on Mineral

Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). NI 43 -101 is a

rule developed by the Canadian Securities Administrators, which establishe d standards for all public disclosure an

issuer makes of scientific and technical information concerning mineral projects. Mining disclosure in the United

States was previously required to comply with SEC Industry Guide 7 (“SEC Industry Guide 7”) under the United

States Securities Exchange Act of 1934, as amended. The U.S. Securities and Exchange Commission (the “SEC”)

has adopted final rules, to replace SEC Industry Guide 7 with new mining disclosure rules under sub -part 1300 of

Regulation S -K of the U.S. Securities Act (“Regulation S -K 1300”) which became mandatory for U.S. reporting

companies beginning with the first fiscal year commencing on or after January 1, 2021. Under Regulation S-K 1300,

the SEC now recognizes estimates of “Measured Mineral Resourc es”, “Indicated Mineral Resources” and “Inferred

Mineral Resources”. In addition, the SEC has amended its definitions of “Proven Mineral Reserves” and “Probable

Mineral Reserves” to be substantially similar to international standards.

Investors are cautioned that while the above terms are “substantially similar” to CIM Definitions, there are differences

in the definitions under Regulation S-K 1300 and the CIM Standards. Accordingly, there is no assurance any mineral

reserves or mineral resources that the Company may report as “proven mineral reserves”, “probable mineral

reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI

43-101 would be the same had the Company prepared the mineral reserve or mineral resource estimates under the

standards adopted under Regulation S -K 1300. U.S. investors are also cautioned that while the SEC recognizes

“measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under Regulation S-K

1300, investors should not assume that any part or all of the mineralization in these categories will ever be converted

into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has

a greater degree of uncertainty as to its existence and feasibility than mineralization that has been characterized as

reserves. Accordingly, investors are cautioned not to assume that any measured mineral resources, indicated mineral

resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable.

Cautionary non-GAAP Measures and Additional GAAP Measures

Note that for purposes of this section, GAAP refers to IFRS. The Company believes that investors use certain non-

GAAP and additional GAAP measures as indicators to assess gold mining companies. They are intended to provide

additional information and should not be considered in isolation or as a substitute for measures of performance

prepared with GAAP.

“Cash flow from operating activities before changes in non -cash working capital” is a non -GAAP performance

measure that could provide an indication of the Company’s ability to generate cash flows from operations, and is

calculated by adding back the change in non-cash working capital to “Cash provided by (used in) operating activities”

as presented on the Company’s consolidated statements of cash flows. “Free cash flow” is a non-GAAP performance

measure that is calculated as cash flows from operations net of cash flo ws invested in mineral property, plant and

equipment and exploration and evaluation assets as presented on the Company’s consolidated statements of cash

flows and that would provide an indication of the Company’s ability to generate cash flows from its min eral projects.

“Mine site free cash flow” is a non-GAAP measure which includes cash flow from operating activities at, less capital

expenditures at each mine site. Return on Equity is defined as Earnings from Continuing Operations divided by the

average Total Equity for the current and previous year. “Mining cost per tonne of ore” and “Cost per tonne of ore”

are non-GAAP performance measures that could provide an indication of the mining and processing efficiency and

effectiveness of the mine. These measures are calculated by dividing the relevant mining and processing costs and

total costs by the tonnes of ore processed in the period. “Cost per tonne of ore” is usually affected by operating

efficiencies and waste-to-ore ratios in the period. “Total cash c osts per ounce”, “all -in sustaining costs per ounce”,

and “mine-site all-in sustaining costs” as used in this analysis are non -GAAP terms typically used by gold mining

companies to assess the level of gross margin available to the Company by subtracting th ese costs from the unit

price realized during the period. These non-GAAP terms are also used to assess the ability of a mining company to

generate cash flow from operations. There may be some variation in the method of computation of these metrics as

determined by the Company compared with other mining companies. In this context, “total cash costs” reflects mining

and processing costs allocated from in-process and doré inventory associated and associated royalties with ounces

of gold sold in the period. Total cash costs per ounce are exclusive of exploration costs. “All-in sustaining costs per

ounce” include total cash costs, exploration, corporate and administrative, share based compensation and sustaining

capital costs. “Mine-site all-in sustaining costs” include total cash costs, exploration, and sustaining capital costs for

the mine-site, but exclude an allocation of corporate and administrative and share based compensation.

Additional GAAP measures that are presented on the face of the Company’s consoli dated statements of

comprehensive income and are not meant to be a substitute for other subtotals or totals presented in accordance

with IFRS, but rather should be evaluated in conjunction with such IFRS measures. This includes “Earnings from

operations”, which is intended to provide an indication of the Company’s operating performance, and represents the

amount of earnings before net finance income/expense, foreign exchange gain/loss, other income/loss, and income

tax expense. Non -GAAP and additional GAA P measures do not have a standardized meaning prescribed under

IFRS and therefore may not be comparable to similar measures presented by other companies. A reconciliation of

historical non-GAAP and additional GAAP measures are available in the Company’s latest Management’s Discussion

and Analysis available online on the SEDAR website at www.sedar.com or on EDGAR at www.sec.gov and at

www.alamosgold.com.
