Morovits Mine; Morovich Mine
A gold mine near the headwaters of Swift Creek. The ore occurred in pyritized shear zones near the contact between a small quartz diorite stock and argillaceous sedimentary rocks of the Chilliwack Group. It produced a small amount of ore prior to 1912. Development consisted of many small adits. A small stamp mill was built near the creek and was connected to the mine with a tramway.
