Alamos Gold Announces Significant Permitting Milestones at Lynn Lake Gold

Project

TORONTO, March 06, 2023 -- Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today announced that

the federal Environmental Impact Assessment (“EIS”) for the Lynn Lake Gold Project (“Lynn Lake”) has been completed and a

positive Decision Statement has been issued by the Minister of Environment and Climate Change Canada. As well, in

accordance with the Environment Act, the Province of Manitoba has issued Environment Act Licenses for the MacLellan and

Gordon sites.

“Achieving both of these important regulatory milestones for the Lynn Lake Gold Project represents a multi-year, collaborative

effort by our team and our commitment to environmental sustainability,” said John A. McCluskey, President and Chief

Executive Officer. “Lynn Lake is a significant opportunity to drive the future growth of our business in Canada, with the potential

to increase our annual production to approximately 800,000 ounces of gold per year.”

Having achieved these milestones, the Company will continue obtaining other project related permits. The negotiation of formal

agreements with directly affected First Nations will also continue.

Since the completion of the 2017 Feasibility Study on the Lynn Lake Project, exploration success around the Gordon and

MacLellan deposits have driven a 27% increase in Mineral Reserves to 2.1 million ounces of gold (36.5 million tonnes (“mt”)

grading 1.75 grams per tonne of gold (“g/t Au”)). This growth along with additional exploration success over the past several

years will be incorporated into an updated Feasibility Study which is expected to be completed during the first half of 2023.

With a large underexplored land package with significant potential, exploration will remain a key ongoing focus with $5 million

budgeted at the Lynn Lake Project in 2023. This includes 8,000 metres of drilling focused on several advanced regional

targets, expansion of Mineral Reserves and Resources in proximity to the Gordon deposit, as well as targeting and evaluation

of the Burnt Timber and Linkwood deposits. Burnt Timber and Linkwood contain Inferred Mineral Resources totaling 1.6 million

ounces grading 1.1 g/t Au (44.4 mt) as of December 31, 2022 and represent potential future upside.

The other key area of focus for 2023 is the continued evaluation and advancement of a pipeline of prospective exploration

targets within the 58,000-hectare Lynn Lake Property including the Tulune greenfields discovery and the Maynard target.

“will” be taken, occur or be achieved or the negative connotation of such terms.

Forward-looking statements in this news release include, but may not be limited to, statements, expectations and information

pertaining to: the development of the Lynn Lake Gold Project; the Lynn Lake Gold Project’s potential to drive future growth of

the Company’s business; the potential for an increase in the Company’s annual production of gold and the expected number of

yearly ounces of increase per year that would be attributed to the Lynn Lake Gold Project if developed; the Company’s intent

to continue obtaining other project related permits; the expected receipt of other project related permits; ongoing negotiations

with affected First Nations; the expected completion of an updated Feasibility Study for the Lynn Lake Gold Project and the

expected timing of its completion; intentions with respect to exploration, including budgets, targets and the potential future

upsides relating to intended exploration; the potential expansion of Mineral Reserves and Resources in proximity to the

Gordon deposit; the Company’s intent to target and evaluate the Burnt Timber and Linkwood deposits and the expected

Inferred Mineral Resources and gold grades contained therein; expected focus on the continued evaluation and advancement of

a pipeline of prospective exploration targets surrounding the Lynn Lake property; and, other statements that express

management’s expectations or estimates of future plans and performance, operational, geological or financial results,

estimates of amounts not yet determinable and assumptions of management.

Alamos cautions that forward-looking statements are necessarily based upon a number of factors and assumptions that, while

considered reasonable by Alamos at the time of making such statements, are inherently subject to significant business,

economic, technical, legal, political and competitive uncertainties and contingencies. Known and unknown factors could cause

Note to U.S. Investors – Mineral Reserve and Resource Estimates

Mineral Resource and Mineral Reserve estimates referenced in this news release are made in accordance with National

Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy

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

established 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 Resources”, “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 or referenced 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.
