Ptarmigan and Tom Mine The Ptarmigan and Tom Mine were gold producers located in the Northwest Territories, Canada at Yellowknife. The property was staked by prospectors in 1936 and acquired by Cominco in 1938. The mine first produced between 1941 and 1942 but closed due to wartime restrictions. The old property was demolished in 1969–1970. A new company, Treminco Resources Limited, reopened the workings in 1985 and production from the Tom ( ) portal began in 1986 with material being trucked to Giant Mine. The old Ptarmigan ( ) mine shaft was dewatered and production began in 1987. A new mill was built at the property and was operational in July 1989. Low gold prices forced the company to close the mines in 1997. Total gold production has been approximately 120,000 troy ounces (3700 kg).

Mk 3 mine The Mk 3 mine or Mine G.S. Mk III was a British anti-tank mine used during World War II. The mine had a cylindrical tin lower body with a steel pressure plate which sits on top of a shear-wire restrained spring-loaded striker. Sufficient pressure on the cover shears the restraining wire, allowing the striker spring to push the striker into a 1.7 gr percussion cap.

Woodsmith Mine Woodsmith Mine is a deep potash and polyhalite mine located near to the hamlet of Sneatonthorpe, Whitby in North Yorkshire, England. The venture was started by York Potash Ltd, which became a subsidiary of Sirius Minerals plc whose primary focus is the development of the polyhalite project. The project will mine the world’s largest deposit of polyhalite – a naturally occurring mineral. Because the project would require mining to be undertaken in the North York Moors National Park, many objections were raised to the mine and the proposed conveyor that would be installed to transport the raw material offsite to a plant on Teesside 37 km away.
