According to the 1917 "History of Chelmsford Massachusetts" (Rev. Wilson Waters at p659) the Copperas Mine "was located on the southerly slope of Robin's hill, and is said to have been worked to a depth of over fifty feet. Very little can be learned about it, as the mine probably has not been worked for over one hundred years, and it is now filled with stones and other refuse matter. It is said to have yielded a dark, rotten rock of greenish hue, from which copperas was obtained, which was locally used in the tanning and manufacture of leather. There were eight or ten tanning vats by the small brook on Bartlett Street, in Chelmsford, a larger number in Westford, and several vats in Acton, which created a demand for the product of this mine. The material taken out, if we may judge of it from the name given to the mine, was probably partially decomposed or weathered iron pyrites, which by oxidation and other natural processes produced copperas. By simple artificial imitative processes, this mineral would yield the ferrous sulphate commercially known as green vitriol or copperas."
