Ballycorus (Irish: Baile Mhic Fheorais, meaning 'Town of the Pearse Family')[1] leadmines is a former lead mining and smelting centre located in the townland of the same name, near Kilternan in County Dublin, Ireland.

The most distinctive surviving remnant of the site is the ruin of the flue chimney that lies close to the summit of Carrickgollogan hill.

[3] The ore from Luganure was carried by horse and cart to the railway station at Rathdrum where it was transferred to a train and brought to Shankill.

[5] The lead, which was used to manufacture pipes and roofing, found a ready market in the Dublin building trade as the city's suburbs began to expand.

[5] To this end a flue 1+1⁄4 miles (2 kilometres) long running from the lead works and terminating at a chimney near the summit of Carrickgollogan was constructed in 1836.

[10] The distinctive granite flue chimney with its external spiral staircase and viewing platform quickly became a noted landmark and was marked on Admiralty charts as a point of reference for mariners.

[9] Photographic records show that the flue chimney was originally much taller with an extra brick section, now dismantled, rising above the viewing platform.

These industrial buildings, all built from granite, include furnaces, purification tanks, lime kilns, stores, workers' cottages and the manager's house.
