Additional highlights for the first quarter ended March 31, 2022, are summarized below:

Strategic

• For the eighth consecutive year, the Don David Gold Mine earned the prestigious Empresa Socialmente Responsable (�ESR�) award from the Mexican Center for Philanthropy (CEMEFI). Awards are given to organizations who demonstrate a commitment to supporting social and environmental protection programs within their local communities.
• During the quarter, the Company purchased and processed a thousand tonnes of tailings material from a nearby community in an effort to ensure the proper environmental treatment and storage of the material.
• Patrick Frenette was hired as Vice President, Technical Services and Steve Donohue was seconded as Vice President, Environmental and Regulatory Affairs (Michigan) to further derisk the successful delivery of the optimized feasibility study and permit applications for the Back Forty Project.

Financial

• Working capital was $32.4 million at March 31, 2022, $3.1 million higher than at December 31, 2021. The increase is primarily due to an increase in accounts receivables as a result of higher base metal prices and timing of shipments in March.
• Total cash cost for the quarter was $ (121) per gold equivalent (�AuEq�) ounce (after co-product credits) and Total all-in sustaining cost for the quarter was $499 per AuEq ounce (after co-product credits). Both non-GAAP measures were favorably impacted by co-product credits for base metals.¹
