There were several other mines in the immediate area near the Missouri line. There were the Thompson Mine (Troublesome Mine), Coal City Coal Co. and the Heim Mine. They were quite small and little is known about them.
There were also mines in Missouri very close to the Iowa border. One of these was the Ball Mine. George Ball, 35, and Frank Ball, 65, were killed in a mine cave-in accident. They were working on a new tunnel in a slope mine when a section of batt gave way, crushing Frank Ball to death. His son George was working several feet away and rushed to help his dad only to be caught when another section gave way, and he too was killed immediately. Help was rushed from the Guinn and Moore mines and the bodies were extricated from the mass of fallen rock, earth and slate.
Other Missouri mines were the Moore Mine and the Raven Mine. The Raven Mine was often called the Snake Pit Mine because of the many snakes that moved along the ledges in the entry in the winter.
