Copper Mines opened pre-1850. Large scale production began in 1866. Ore is chalcopyrite both in pure masses and disseminated in pyrrhotite.

Richardson (1897) commented on limburgite at this locality: "During the summer of 1896, while engaged in field work in stratigraphical geology, I encountered many dikes of [limburgite] diabase rich in olivine, and others of the same microscopical appear­ance as the typical camptonite in the Pemigewassett Valley, N. H.
By diligent investigation it was my good fortune last August to discover in the locality of these ramifying dikes and the famous Corinth copper mines an extraordinary dike of limburgite, from 6 to 10 feet in width, and penetrating the calciferous mica schist toward the west for more than half a mile. This limburgite bears individual crystals of olivine two to three inches in length and one to two inches in breadth. A single specimen has been placed in the museum of Dartmouth Some of the smaller crystals by the oxidation of the iron have become converted into limonite or hematite; others have gove over into serpentine, while a bit of calcite derived from the contiguous orthorhombic pyroxene or the basic plagioclase feldspar is occasionally seen in the cavities once filled by the original olivine crystals.
As the locality is to the northward in the exact direction of the moving ice [of Pleistocene ice sheets], and at a distance of only about twenty miles from the famous Thetford boulders, it seems evident that Corinth, Vt, was their original habitat."
