Toronto, Ontario – (April 12, 2018) Argonaut Gold Inc. (TSX: AR) (the “Company”, “Argonaut Gold” or “Argonaut”) reports that its wholly-owned subsidiary that owns the La Colorada mine has had its permit for the use of explosives at the site temporarily suspended as a result of a pending legal action brought by four individuals against the Secretary of National Defense (“SEDENA”) and the Municipality of La Colorada. Activities at site continue unaffected due to the availability of blasted and stockpiled material adequate to allow for operations to continue normally. Stockpiles are sufficient that operations will continue normally through at least April 16, 2018, at which time there is a hearing scheduled where Argonaut hopes to resolve the issue.
