Drumlummon Mine oldtimers explored the 29 miles of shafts that were drilled, chipped and blasted into honeycomb maze - that made Marysville and millionaires -
Miners left their mark up and down the mine shafts - The No. 1 Shaft Station is a 30-by-60 foot wide room with a 50 foot tall ceiling full of stopes. The stopes were made when miners blasted upward so the ore would fall down, making it more easily shipped out in ore cars.
