TORONTO, ONTARIO–(Marketwired – Sept. 21, 2017) –

All amounts are in United States dollars, unless otherwise stated.

Alamos Gold Inc. (TSX:AGI)(NYSE:AGI) ("Alamos" or the "Company") is pleased to announce that it has secured amendments to its existing undrawn revolving credit facility (the "Facility") including an increase in the size of the Facility from US$150 million to US$400 million on more favourable terms.

Under the amended Facility, the Company will benefit from improved pricing at its current leverage ratio including undrawn fees of 0.45% and drawn fees of LIBOR plus 2.00%. This compares to undrawn fees of 0.48% and drawn fees of LIBOR plus 2.125% under the previous credit facility. The Facility remains undrawn and the Company debt free with cash and equity securities of approximately US$150 million as of June 30, 2017. The maturity date of the Facility has been extended to September 20, 2021.

"The amended facility adds significant liquidity on very attractive terms. Combined with existing cash and expected cash from the recently announced acquisition of Richmont Mines, Alamos will be debt free with more than US$600 million of available liquidity. This greatly improves our financial flexibility as we fund development of our portfolio of growth projects," said John A. McCluskey, President and Chief Executive Officer.

The amended Facility was joint-led by the Bank of Nova Scotia, BMO Capital Markets, and TD Securities. Additionally, the syndicate includes the Canadian Imperial Bank of Commerce, National Bank of Canada, HSBC Bank Canada, ING Capital LLC, and Export Development Canada.

The effectiveness of the Facility is subject to satisfying certain customary closing conditions which have been delayed due to the earthquake in Mexico and are expected to be completed in the coming days.
