"Alamos Gold was founded 20 years ago this month with a market capitalization of less than $50 million, the Mulatos project, and a vision. Today, Alamos is a growing, diversified intermediate gold producer with a market capitalization of more than $4 billion, and a long-term track record of creating value for all of our stakeholders. With a portfolio of high-quality operations in Canada and Mexico, and a strong, fully funded development pipeline, our outlook has never been stronger. We are on track to deliver growing production and a substantial decrease in costs over the next several years, driving strong free cash flow growth. We are honoured to be ringing the opening bell to celebrate these two important anniversaries and a bright future," said John A. McCluskey, President and Chief Executive Officer.
