First Mining Gold announced the immediate departure of president-CEO Jeff Swinoga.
In a very brief Oct. 16 news release, board chairman Keith Neumeyer wished him well.
Board member David Shaw is the interim CEO while the board starts the search for a successor.
The Vancouver-headquartered junior miner has 24 properties in North America and Mexico, including its Springpole project, northeast of Red Lake, one of four properties in northwestern Ontario.
