Madawaska Mine (previously known as Faraday Mine) is a decommissioned underground uranium mine in Faraday, near the town of Bancroft, Ontario, which produced 9 million pounds (4,082 tonnes) of U3O8 concentrate, at an average ore grade of 0.1074%, during its two periods of production. Madawaska Mine
produced uranium for the longest period out of the four nearby mines (the three others being Bicroft Mine, Greyhawk Mine, and Dyno Mine). Aside from uranium, the mine is also a renowned source of calcite crystals, ilmenite crystals, kainosite-(Y), Molybdenite, and uranophane crystals.
