Mining was what put Franklin NJ on the map, from the early days of the Franklin Furnace, to the later days of the Palmer Zinc Mine. Franklin had about 3 scattered zinc mines all about in the late 1800's. The number of shafts, tunnels, cuts, excavations etc where too many to name. The Trotter, Parker and Palmer mines where all consolidated by the NJ Zinc company back in the early 1900's and worked from the Palmer mine area. The Mine itself was huge, and all the ore was mined until exhausted ub 1954. The grounds Boasted a rail road yard with over 6 tracks in it. a Large mill and a 1000+ foot 60 degree shaft. unfortunately all that remains is being slowly neglected. The entrances capped with impenetrable cement.
