All amounts are in United States dollars, unless otherwise stated.
TORONTO, Feb. 18, 2020 -- Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today reported its
updated Mineral Reserves and Resources as of December 31, 2019. For a detailed summary of Mineral Reserves and
Resources by project, refer to the tables below.
Highlights
◾ Island Gold’s Mineral Reserves and Resources increased by a combined 921,000 ounces, net of mining
depletion, including:
◦ 21% increase in Proven and Probable Mineral Reserves to 1.22 million ounces (3.6 million tonnes (“mt”)
grading 10.37 grams per tonne of gold (“g/t Au”)), net of mining depletion
◦ 46% increase in Inferred Mineral Resources to 2.30 million ounces (5.4 mt grading 13.26 g/t Au) with
grades also increasing 13% reflecting higher grade additions in Island East
◦ Combined Mineral Reserves and Resources now total 3.70 million ounces, double the 1.84 million ounces
at the time of acquisition in 2017, net of 364,000 ounces of mining depletion
◾ Global Proven and Probable Mineral Reserves of 9.73 million ounces of gold (203 mt grading 1.49 g/t Au), up
slightly from 9.70 million ounces at the end of 2018 with increases primarily at Island Gold offsetting 576,000 ounces of
mining depletion
◾ Global Measured and Indicated Mineral Resources of 7.04 million ounces of gold (199 mt grading 1.10 g/t Au),
down 3% reflecting the conversion to Mineral Reserves at Young-Davidson
◾ Global Inferred Mineral Resources increased 10% to 5.98 million ounces of gold (130 mt grading 1.43 g/t Au),
with grades also increasing 10% driven by the 725,000 ounce increase at Island Gold
◾ Global exploration budget of $36 million in 2020, a 24% increase from the $29 million spent in 2019. This includes
$21 million at Island Gold focused on defining additional near mine Mineral Reserves and Resources, $7 million
budgeted at Mulatos and $5 million budgeted at Lynn Lake
“We had another tremendous year at Island Gold on all fronts with the asset continuing to evolve into a world class ore body.
Over the past two years we have added more than two million ounces of Mineral Reserves and Resources, before mining
depletion, with the deposit now approaching four million ounces in all categories. We see strong potential for this growth to
continue with the deposit open laterally and down-plunge across multiple areas of focus,” said John A. McCluskey, President
and Chief Executive Officer.
“The majority of this growth is being incorporated into a Phase III expansion study of Island Gold supporting what we expect
will be a larger, increasingly profitable, long-life operation in one of the best mining jurisdictions in the world,” Mr. McCluskey
added.

Mineral Reserves
Global Proven and Probable Mineral Reserves total 9.73 million ounces of gold as of December 31, 2019. This is up slightly
from 9.70 million ounces at the end of 2018 with increases at Island Gold, Young-Davidson, La Yaqui Grande and Kirazlı
offsetting mining depletion of 576,000 ounces in 2019.
Island Gold continues to be the driver of Mineral Reserve and Resource growth within Alamos with another significant increase
in high-grade ounces. Mineral Reserves increased 21% in 2019 to 1.2 million ounces despite the focus being on extending
high-grade mineralization and adding near mine Mineral Resources. A total of 361,000 ounces of Mineral Reserves were
added, more than offsetting mining depletion of 153,000 ounces. Mineral Reserve grades also increased slightly to 10.37 g/t
Au with higher grade additions more than offsetting the higher grades mined in 2019. Since the acquisition of Island Gold in
November 2017, Mineral Reserves have increased 62%, net of depletion, with Mineral Reserve grades also increasing 13%.
Young-Davidson’s Mineral Reserve of 3.15 million ounces decreased 116,000 ounces from 2018 with mining depletion partially
offset by an increase in Mineral Reserves in the lower mine. The additions were driven by conversion of existing Mineral
Resources through stope definition drilling below current mining horizons. This contributed to a slight decrease in the Mineral
Reserve grade to 2.60 g/t Au, from 2.67 g/t Au, at the end of 2018. No exploration drilling has been conducted at Young-
Davidson since 2013 given the large Mineral Reserve base and the costly nature of drilling from surface. With the deposit open
at depth and access now available to drill from the bottom of the mine, this will be an increasing focus going forward.
Mineral Reserves at Mulatos decreased 154,000 ounces to 1.56 million ounces with mining depletion partially offset by an
81,000 ounce increase at La Yaqui Grande. The majority of the exploration activities conducted in 2019 were focused on
earlier stage work. The 2020 exploration budget has been increased to $7 million at Mulatos with more drilling planned around
near mine targets as well as at La Yaqui Grande and El Carricito.
Mineral Reserves at Kirazlı increased 87,000 ounces to 0.75 million ounces reflecting the conversion of existing Mineral
Resources. The conversion was the result of an optimized pit design which incorporated lower costs than utilized in the 2017
Feasibility Study, reflecting the weaker Turkish Lira and lower mining costs confirmed with the 2019 mining contract.
A $1,250 per ounce gold price assumption was used in estimating 2019 Mineral Reserves, unchanged from 2018. A detailed
summary of Proven and Probable Mineral Reserves as of December 31, 2019 is presented in Table 1 at the end of this press
release.
Mineral Resources
Global Measured and Indicated Mineral Resources (exclusive of Mineral Reserves) totaled 7.0 million ounces as of December
31, 2019. This is down 206,000 ounces, or 3%, from 2018 largely reflecting the conversion of Mineral Resources to Reserves
at Young-Davidson and Kirazlı.
Global Inferred Mineral Resources totaled 6.0 million ounces as of December 31, 2019, a 10% increase from 2018 with grades
also increasing 10%. This was driven by the addition of 725,000 high-grade ounces at Island Gold.
The Company’s $1,400 per ounce gold price assumption for estimating Mineral Resources is unchanged from 2018. Detailed
summaries of the Company’s Measured and Indicated Mineral Resources and Inferred Mineral Resources as of December 31,
2019 are presented in Tables 3 and 4, respectively, at the end of this press release.
Island Gold
Exploration drilling at Island Gold continues to successfully extend high-grade mineralization and add near mine Mineral
Resources across the down-plunge and lateral extensions of the Island Gold deposit. This was particularly successful in the
eastern portion of the deposit (“Island East”) where the bulk of the 2019 Mineral Resource growth occurred, including in the
new area of focus.
Island Gold’s Mineral Reserves increased to 1.2 million ounces, a 208,000 ounce or 21% increase from the end of 2018, net of
mining depletion. This included a 361,000 ounce increase in Mineral Reserves, less mining depletion of 153,000 ounces, in
2019. Mineral Reserve grades also increased 1% to 10.37 g/t Au from the end of 2018 with the higher grade additions more
than offsetting the higher grades mined in 2019 of 12.28 g/t Au. All of the gains were made within the Island Main and Island
East portions of the deposit. (See Figure 1 at the end of this press release.)
Based on throughput rates of 1,200 tonnes per day (“tpd”), Island Gold has a current Mineral Reserve life of approximately
eight years. With ongoing exploration success, an already large Mineral Resource base, and strong track record of conversion
to Mineral Reserves, the Company expects Island Gold’s ultimate mine life will be significantly longer.
Measured and Indicated Mineral Resources decreased 6% to 184,000 ounces with grades also decreasing to 6.51 g/t Au from
the end of 2018 reflecting the conversion to Mineral Reserves, primarily in the upper portion of Island East.
Inferred Mineral Resources increased 46%, or 725,000 ounces, to 2.3 million ounces with grades also increasing 13% to 13.26
g/t Au compared to the end of 2018. The strong increase in Mineral Resources and grade were driven by higher grade
additions in Island East, including:
• An initial Inferred Mineral Resource of 301,000 ounces grading 16.06 g/t Au in the new area of focus. This area is
located 180 m down-plunge from Mineral Reserves in Island East and had not seen any drilling prior to 2019. All 17
holes drilled to date in this area have intersected the Island Gold Main Zone with this area open both up- and down-
plunge (see Figure 2)
• A 443,000 ounce increase in Inferred Mineral Resources, 200 m down-plunge from the new area of focus in the lower
portion of Island East. This area now contains 720,000 ounces grading 18.74 g/t Au. This east plunging high-grade ore
shoot remains open laterally, and up- and down-plunge
Testing the continuity of high-grade mineralization between the Mineral Reserves in the upper portion of Island East to Mineral
Resources in the lower portion will be an ongoing focus of both surface and underground exploration drilling in 2020.
Since the acquisition of Island Gold in 2017,
◾ Mineral Reserves have increased 827,000 ounces before mining depletion, or 463,000 ounces net of mining
depletion, with Mineral Reserve grades increasing 13%
◾ Measured and Indicated Mineral Resources have increased 102% or 93,000 ounces, with grades increasing
10%
◾ Inferred Mineral Resources have increased 131%, or 1,302,000 ounces, with grades increasing 30%
Reflecting the ongoing exploration success, the 2020 exploration budget at Island Gold has been increased to $21 million, up
from $17 million spent in 2019. The ongoing focus remains on adding near-mine Mineral Resources and extending high-grade
mineralization in the Western, Main and Eastern portions of the Island Gold deposit with each open laterally and down-plunge.
Young-Davidson
Mineral Reserves at Young-Davidson decreased 116,000 ounces to 3.2 million ounces of gold. This reflects mining depletion of
203,000 ounces, partially offset by an increase of 88,000 ounces in the lower mine through the conversion of existing Mineral
Resources. The conversion of the Mineral Resources was at lower grades contributing to a slight decrease in the Mineral
Reserve grade to 2.60 g/t Au from 2.67 g/t Au. Exploration has not been a priority the last several years given the large
existing Mineral Reserve base and with the focus on completing the lower mine expansion. With the lower mine expansion
expected to be completed in June 2020 and underground drill platforms now available at depth, exploration activities are
expected to resume in 2020. With the deposit open at depth and to the west, Young-Davidson has excellent exploration
potential.
Measured and Indicated Mineral Resources of 1.2 million ounces and Inferred Mineral Resources of 0.1 million ounces both
decreased slightly from a year ago, in part reflecting the conversion of Mineral Resources to Reserves. The Company expects
to continue converting Mineral Resources to Reserves through additional stope definition and infill drilling.
Based on expected underground mining rates, the remaining Mineral Reserve life of the Young-Davidson mine is approximately
13 years as of December 31, 2019.
Mulatos
Total Mulatos District Mineral Reserves (including La Yaqui Grande and Cerro Pelon) decreased 154,000 ounces to 1.6 million
ounces with grades increasing slightly to 1.18 g/t Au. This reflects mining depletion partially offset by additions at La Yaqui
Grande.
Mineral Reserves at La Yaqui Grande increased 13% to 724,000 ounces with Mineral Reserve grade decreasing 7% to 1.17 g/t
Au. The increase was driven by an optimization of the open pit design which brought additional ounces into the mine plan, at
slightly lower grades. La Yaqui Grande’s higher grades (relative to the Mulatos Mine) are expected to support lower cost
production than currently from the Mulatos Mine. The Company expects to finalize the project economics for La Yaqui Grande
and make a construction decision during the second quarter of 2020.
The remaining Mineral Reserve life of the Mulatos District is approximately six years as of December 31, 2019.
Measured and Indicated Mineral Resources of 2.6 million ounces and Inferred Mineral Resources of 0.3 million ounces at
Mulatos are largely unchanged from a year ago.
The 2020 exploration budget for Mulatos has increased to $7 million and includes 14,000 m of drilling focused in the Mulatos
near-mine, Carricito and La Yaqui Grande areas. A number of regional exploration targets have been identified in 2019 from the
property-wide VTEM geophysical survey that was completed in late 2018. A focus of the 2020 regional exploration program will
be to further evaluate these targets through systematic mapping, sampling, and ground geophysics.
Kirazlı
Mineral Reserves at Kirazlı increased 13%, or 87,000 ounces, to 752,000 ounces with grades decreasing 13% to 0.69 g/t Au.
The increase was driven by an optimization of the open pit design through the application of lower mining contract rates and
updated pit slope parameters.
Measured and Indicated Mineral Resources decreased reflecting the conversion to Mineral Reserves. Inferred Mineral
Resources increased reflecting a larger Mineral Resource pit resulting from the new optimization parameters.
Lynn Lake, Ağı Dağı, Çamyurt, Esperanza and Quartz Mountain
Mineral Reserves and Resources for the Lynn Lake, Ağı Dağı, Çamyurt, Esperanza and Quartz Mountain projects are
unchanged from a year ago.

This news release includes certain statements that constitute forward-looking information within the meaning of applicable
Canadian and U.S. securities laws ("forward-looking statements"). All statements other than statements of historical fact,
which address events, results, outcomes or developments that Alamos expects to occur are forward-looking statements.
Forward-looking statements are generally, but not always, identified by the use of forward-looking terminology such as
“continue”, "expect", "plan", "estimate", “target”, “budget” or “potential” or variations of such words and phrases and similar
expressions or statements that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or

to planned exploration programs, costs and expenditures, project economics, changes in mineral resources and conversion of
mineral resources to proven and probable reserves, and other information that is based on forecasts of future operational or
financial results, estimates of amounts not yet determinable and assumptions of management.
Exploration results that include geophysics, sampling, and drill results on wide spacings may not be indicative of the
occurrence of a mineral deposit. Such results do not provide assurance that further work will establish sufficient grade,
continuity, metallurgical characteristics and economic potential to be classed as a category of Mineral Resource. A Mineral
Resource that is classified as "inferred" or "indicated" has a great amount of uncertainty as to its existence and economic and
legal feasibility. It cannot be assumed that any or part of an "Indicated Mineral Resource" or "Inferred Mineral Resource" will
ever be upgraded to a higher category. Investors are cautioned not to assume that all or any part of mineral deposits in these
categories will ever be converted into Proven and Probable Reserves.
Alamos cautions that forward-looking statements are necessarily based upon several factors and assumptions that, while
considered reasonable by the Company at the time of making such statements, are inherently subject to significant business,
economic, legal, political and competitive uncertainties and contingencies. Known and unknown factors could cause actual
results to differ materially from those projected in the forward-looking statements. These factors and assumptions include, but
are not limited to: changes to current estimates of mineral reserves and resources; conclusions of economic and geological
evaluations; changes in project parameters as plans continue to be refined; changes to production estimates (which assume
accuracy of projected ore grade, mining rates, recovery timing and recovery rate estimates and may be impacted by
unscheduled maintenance, labour and contractor availability and other operating or technical difficulties); fluctuations in the
price of gold; changes in foreign exchange rates (particularly the Canadian dollar, Mexican peso, Turkish Lira and U.S. dollar);
the impact of inflation; employee and community relations (including maintaining social license to operate in Turkey); litigation
and administrative proceedings; disruptions affecting operations; availability of and increased costs associated with mining
inputs and labour; development delays at the Kirazlı project or the Young-Davidson mine; inherent risks associated with mining
and mineral processing; the risk that the Company’s mines may not perform as planned; uncertainty with the Company’s
ability to secure additional capital to execute its business plans; the speculative nature of mineral exploration and
development, the renewal of the Company’s mining concessions in Turkey; timely resumption of construction and development
at the Kirazlı project; the risks of obtaining and maintaining necessary licenses, permits and authorizations for the Company’s
development and operating assets; labour and contractor availability (and being able to secure the same on favourable terms);
contests over title to properties; expropriation or nationalization of property; inherent risks and hazards associated with mining
including environmental hazards, industrial accidents, unusual or unexpected formations, pressures and cave-ins; changes in
national and local government legislation (including tax legislation), controls or regulations in Canada, Mexico, Turkey, the
United States and other jurisdictions in which the Company does or may carry on business in the future; risk of loss due to
sabotage, protests and other civil disturbances; the impact of global liquidity and credit availability and the values of assets
and liabilities based on projected future cash flows; risks arising from holding derivative instruments; and business
opportunities that may be pursued by the Company.

Cautionary Note to U.S. Investors – Mineral Reserve and Resource Estimates
All resource and reserve estimates included in this news release or documents referenced in this news release have been
prepared in accordance with Canadian 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. The terms "Mineral Reserve", "Proven Mineral Reserve" and "Probable
Mineral Reserve" are Canadian mining terms as defined in accordance with NI 43-101 and the CIM Standards. These
definitions differ materially from the definitions in SEC Industry Guide 7 ("SEC Industry Guide 7") under the United States
Securities Act of 1933 , as amended, and the Exchange Act. Under SEC Industry Guide 7 standards, a "final" or "bankable"
feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow
analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate
governmental authority.
In addition, the terms "Mineral Resource", "Measured Mineral Resource", Indicated Mineral Resource" and "Inferred Mineral
Resource" are defined in and required to be disclosed by NI 43-101 and the CIM Standards; however, these terms are not
defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements
filed with the U.S. Securities and Exchange Commission (the "SEC"). Investors are cautioned not to assume that all or any
part of mineral deposits in these categories will ever be converted into reserves. "Inferred Mineral Resources" have a great
amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be
assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules,
estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, except in very limited
circumstances. Investors are cautioned not to assume that all or any part of an Inferred Mineral Resource exists or is
economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian
regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by
SEC standards as in place tonnage and grade without reference to unit measures.

Notes to Mineral Reserve and Resource Tables:
• The Company’s Mineral Reserves and Mineral Resources as at December 31, 2019 are classified in accordance with
the Canadian Institute of Mining Metallurgy and Petroleum’s “CIM Standards on Mineral Resources and Reserves,
Definition and Guidelines” as per Canadian Securities Administrator’s NI 43-101 requirements.
• Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
• Mineral Resources are exclusive of Mineral Reserves.
• Mineral Reserve cut-off grade for the Mulatos Mine, the Cerro Pelon Pit, the La Yaqui Pit, the Kirazlı Pit and the Ağı
Dağı Pit are determined as a net of process value of $0.10 per tonne for each model block
• All Measured, Indicated and Inferred open pit Mineral Resources are pit constrained with the exception of those outside
the Mulatos Main Pits on the Mulatos property which have no economic restrictions and are tabulated by gold cut-off
grade.
• Mineral Reserve estimates assumed a gold price of $1,250 per ounce and Mineral Resource estimates assumed a gold
price of $1,400 per ounce. Metal prices, cut-off grades and metallurgical recoveries are set out in the table below.
