An early set of mine and shaft openings into the Franklin orebody, just North of the Buckwheat pit on the West leg of the orebody. The latest shaft, circa 1920, was in the footwall of the orebody. This shaft produced unique finds of nickel-cobalt species from the district.

This locality is within the Franklin Mining District. The complete list of mineral species occurring within this district, as well as the official boundaries of the district, can be found under the locality file for "Franklin Mining District." Those who share an interest in the unique mineralogy of the Franklin, NJ, area owe a special debt of thanks to the late Professor Charles Palache, Harvard University; Dr. Pete J. Dunn, Department of Mineral Sciences, National Museum of Natural History, Smithsonian Institution, Washington, D.C.; and John L. Baum, Curator Emeritus, Franklin Mineral Museum, and former Head Geologist, New Jersey, Zinc Co., Franklin, NJ, for their significant contributions to the body of knowledge of the history, geology and mineralogy of this district.
