Steep Rock Iron Mine, Atikokan, Ontario

Steep Rock Iron Mines has not operated for 25 years or so. It was a great iron mine and cranked out high grade iron ore and pellets between 1944 and 1980. It was the first operating mine that I ever visited when I was 14 years old! The iron ore and surrounding rock was strongly brecciated in places and the breccia was often filled with excellent calcite, ankerite, manganese oxides and quartz crystals. Here are some nice examples.

  • When I was fourteen years old, I won a trip to Steep Rock Iron Mines. Every year, the junior mineral club that I belonged to sent two kids off to lean about mining, geology, mineral processing, etc. We had a ball. We stayed at the directors' lodge, visited the open pit mine, the mill, the experimental underground mine and, of course, collected LOTS of great mineral specimens. The rock in and around the hematite ore was heavily brecciated in places and the breccia was often filled with excellent calcite, quartz, iron oxide and manganese oxide crystals.

    Steep Rock operated between 1944 and 1980 cranking out many tonnes of high grade ore and pellets. Mostly full of water now! Here are some interesting specimens from that venerable old producer.

  • A yummy plate of deep-chocolate brown rhombohedral calcite crystals on a matrix of iron carbonate and oxides. Different specimen from this long closed famous iron mine. A little bruising but displays fairly well!
