Very little is known of the Pontiac Mining Company. It was organized in 1859 to explore and mine the Pewabic and Franklin Lodes between the Albany and Boston and Mesnard Mine properties where ancient pits were discovered. It was reported that good barrel copper and masses were found in the shaft, but the overall results were not promising. The company was bought by Quincy in 1897 and work was started on a new shaft in 1908 which was to become the Quincy No. 9 shaft; however, the great strike of 1913 forced Quincy to abandon sinking this shaft. A very small rock pile exists from this shaft sinking in 1908. Some copper can be found.
