Abandoned Lead and Zinc Mine operated during the mid 19th century, occurring in Helderberg limestone. Located along state route 147, South of Sunbury along the Susquehanna River, across from Selinsgrove.

There are four remaining adits which are unmanaged and considered too hazardous to enter.

Reportedly first discovered in the 1840's, ores recovered had been shipped east via the Pennsylvania canal, but the workings remained secretive until 1882 when Mr. Doughty of Shamokin (also noted as from Tamaqua?), undertook a systematic development of the ores. Ore occured as "strings" and "pots" mixed with large amounts of muddy deposits, much resembling that deposited by turbid waters. Deposits ran almost directly E-W at nearly the crest of the Selinsgrove arch, about 10' above the base of the Bossardville Limestone. Both Lead and Zinc occurred chiefly as sulphides, minor copper as carbonate. Analysis of ore conducted by McCreath in 1882 as follows: Metallic Lead - 24.191, Metallic Zinc - 31.954, Metallic Copper - 1.389.
