Executive Team


Celebration of Life
CEO, Stephen D. King

It is with a heavy heart that we inform you of the passing of Stephen D. King.  Steve was recently diagnosed with a particularly aggressive and fast-moving type of cancer. Although he put up as good of a fight as humanly and medically possible, the fight ended September 21, 2020.

His clarity of vision, sharp mind and kind heart made him a joy to work with and be around.  The redevelopment and opening of the Bates Hunter mine was Steve’s vision and now that we are on the very cusp of realizing that dream, his passing is very sad indeed.

The team at GS Mining Company remains focused on the success of the project and on building value for its investors.  We are committed to Steve’s legacy, bringing back the richest square mile on earth.

Our miners, engineers, electricians, managers and officers are at it – literally twenty-four hours a day.
