The story of the Drumlummon Mine is the story of the town. In 1876, a Thomas Cruse discovered the vein and named it after his native town in Ireland. He named the town after the first woman to arrive in Marysville, a Mary Ralston. During the 1880s and 90s, Marysville was Montanaâ€™s leading gold producer and had a population of 3,000 people. Total production from Drumlummon is estimated to have been $50,000,000.
