ALAMOS GOLD RELEASES 2022 ANNUAL ESG REPORT

Alamos Gold Inc. has released its annual environmental, social and governance (ESG) report, which outlines the company's progress on its ESG performance in 2022 across its operations, projects and offices and provides direction on planned initiatives for 2023.

"While sustainability has been at the core of our strategy for over 20 years, we have published this report for the last 10 years in order to track the progress of our sustainability initiatives. I am encouraged by our achievements reflected in this year's report, and we will continue to measure our results against the high standard we have set," said John A. McCluskey, president and chief executive officer.

Alamos' 2022 ESG report, available at the company's website, highlights significant progress achieved by the company during the past year including:

• An 8-per-cent growth in the work force, with 77 per cent hired from local communities to the sites, and a 36-per-cent reduction in employee turnover rate;

• Announced a company-wide target of a 30-per-cent reduction in absolute greenhouse gas (GHG) emissions by 2030, achieving a 6-per-cent reduction in total Scope 1 and 2 GHG emissions in 2022;

• Zero significant environmental incidents during the year, including zero reportable tailings-related incidents;

• $1.8-million invested in local community initiatives including donations, sponsorships, community programs and infrastructure;

• Continued respectful dialogue with impacted indigenous communities in Canada, and finalized two new formal participation agreements during the year;

• The Mulatos mine was awarded the Silver Helmet award by the Mining Chamber of Mexico (Camimex) in recognition of outstanding health and safety performance. Mulatos was also awarded the Socially Responsible company (Empresa Socialmente Responsable) award by Cemefi, the Mexican Centre for Philanthropy, for the 14th consecutive year, and was the recipient for the award for Corporate Ethics and Values in Industry for the third consecutive year;

• Completed close to 1,700 training hours for occupational health and safety and emergency management;

• Introduced the Island gold employee wellness program with licensed physical therapists on site;

• Three years in compliance with the World Gold Council's Responsible Gold Mining Principles (RGMPs), and developed 12 new Alamos sustainability standards.

The 2022 ESG report is guided by the Sustainability Accounting Standards Board (SASB) metals and mining industry standard, the recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD), and the Global Reporting Initiative Standards (GRI) for sustainability reporting "core" requirements. It focuses on economic, environmental, social, and governance topics and indicators that are of the greatest interest to Alamos's stakeholders. Since 2013, Alamos has published an annual sustainability report to provide transparency on its sustainability initiatives and results from its operating mines. Since 2019, the company has branded this publication as an ESG report to reflect the depth of its content and the standards to which it now aligns.
