Additional High-Grade Mineralization Intersected Across The Island Gold Deposit

TORONTO - Alamos Gold Inc. reported new results from underground and surface drilling at the Island Gold Mine. Exploration drilling continues to extend high-grade gold mineralization across the Island Gold Deposit, as well as within several hanging wall and footwall structures. Additionally, the regional exploration program has been successful in intersecting high-grade gold mineralization at the past-producing Cline-Pick and Edwards mines, located seven kilometres from the Magino Mill.

"Island Gold’s Mineral Reserve base has increased for 12 consecutive years. Our ongoing exploration success across the extent of the deposit, as well as within the hanging wall and footwall continues to support our expectation this tremendous pace of growth will continue. This growth highlights the significant near-term upside opportunities we expect to incorporate into the Island Gold District Expansion Study which we expect to release later this year. Additionally, the high-grades being intersected within the nearby Cline-Pick and Edwards past producing mines, highlight the longer-term opportunities for further growth through multiple sources of higher-grade ore feeding a potential larger expansion of the Magino mill,” said John A. McCluskey, President and Chief Executive Officer.

Island Gold Main zone exploration highlights high-grade mineralization extended outside of Mineral Reserves and Resources in the E1E and C-Zones. These zones are the main structures which host the majority of currently defined Mineral Reserves and Resources at Island Gold. New highlights include: 1) Island West (C-Zone). 2) 21.58 g/t Au (21.58 g/t cut) over 5.07 m (1025-503-05). 3) 14.81 g/t Au (14.81 g/t cut) over 2.02 m (1025-503-08). 4) 13.92 g/t Au (13.92 g/t cut) over 3.15 m (1025-497-22). 5) Island East (E1E-Zone). 6) 15.87 g/t Au (15.87 g/t cut) over 2.72 m (945-624-83).

Island Gold Hanging Wall and Footwall exploration highlights: high-grade gold mineralization intersected within new and recently defined hanging wall and footwall zones across the main Island Gold Deposit. These zones represent significant opportunities to continue to grow near mine Mineral Reserves and Resources which are low-cost to develop, given their proximity to existing infrastructure.
