Investigators think a grass fire could be to blame for destroying part of the Goex facilities at Camp Minden. Officials arrived on the scene before firefighters, Saturday night. They had to make sure it was safe for firefighters to go in to put out the blaze. The company`s President said flames reached nealry 100-feet but no one was inside when it happened. Goex is the only manufacturer of Black Powder in North America. A main manufacturing building was destroyed and a couple of hallways. If officials decide to rebuild, it could take up to six months.
