A lead and copper mine operated here at some point before the late nineteenth century, one of many small extractive workings that pocked the Irish landscape during the long industrial push to exploit whatever ore lay beneath farmland and foreshore alike.

The mine's existence is recorded by George Henry Bassett in his 1886 county directory, a volume that catalogued the trades, estates, and industries of Louth in considerable detail. By the time Bassett noted it, the operation may already have been in decline; such small mines frequently opened and closed within a generation, their viability tied to ore prices, drainage costs, and the availability of labour. Lead and copper were often found together in Irish mineral deposits, and workings of this kind typically involved shallow shafts or adits, horizontal tunnels driven into a hillside to follow a seam, rather than the deep-shaft infrastructure of larger industrial mines. The Louth coastline has no particular fame as a mining district, which makes this site a small anomaly in the county's economic history.

The mine is now closed, and little appears to survive above ground in any documented form. Salterstown itself is a quiet coastal spot, and any physical trace of the workings, if it remains at all, would require careful local knowledge to locate.
