Three discinct lead-silver mines [A = Burnt Mills Silver Mine which yielded the geologically dated monazite; B presently inaccessible, but mapped by R. M. Foose in 1947; and C, the best known workings for which the coordinated are provided with the Tulip Poplar Adit nearby. All three located along or near Silver Mine Run, about 1 1/2 miles East of Conestoga and 4 miles NW of Lancaster. Started before 1899.
Pequea Silver Mine C now lies on a Conestoga Township Park. Mineral collecting is forbidden. The site has a self-guided geologic walking trail which is fairly rugged and not handicap accessable. The Pennsylvania Topographic and Geologic Survey featured the mine in their magazine Pennsylvania Geology, Vol. 36 (2006), No. 1 (
