An iron mine in Precambrian meta-sediments. Started about 1950 and closed 1977. Workings feature an open pit.

1950-1951- 40 diamond drill holes were drilled by Bethlehem Steel Corp for a total of 37,000 feet. 1952-1955 - Removal of 22 million tons of limestone, mine and plant construction by Marmoraton Mining Co. Ltd. 1955-1967 - 6,053,145 tons of ore shipped from open pit 1/2 mile long by 1/4 mile wide. 1978 - mining in the pit ceased.

This deposit was visited on July 24th, 2003. The partially water-filled open pit was viewed at the site. Activity on the site is limited to Canada Talc and Aecon Ltd. Canada Talc is utilizing the mill buildings to upgrade their talc from their mine in Huntingdon Township while Aecon continues to crush and ship the limestone caprock for aggregrate.
