Benjamin K. Emerson wrote in 1898
At the Melvin mine... the ore has been removed in an open working about 130 feet on the strike and 35 to 40 feet in depth, to the full width of the bed, which is 6 1/2 feet wide at the north end and opens out for a distance of 33 feet to a width of 16 feet, and then contracts again southward to a width of nearly 10 feet.

The ore is mostly a chloritic magnetite with few accessory minerals, margarite of rare beauty being the only interesting occurrence. A little tourmaline is present. The epidotic amphibolite appears in a thin band on the east of the emery bed, separating it from the sericite-schist farther east, and on the west the same amphibolite adjoins the bed and makes up the whole western half of the mountain.
