Opened in 1838, Lanivet Consols, amalgamated with Tregollan Mine in 1839 as Tretoil Consolidated Mines, lies one and a half miles southeast of Lanivet. It includes Wheal Messar and the former sett of Blackheath or East Tretoil Mine.

Recorded output:

Tretoil: 1838-39, 1858, 1874, 1875 & 1882: 11,755 tons of 7.25% copper ore and 30 tons of black tin.

Messar: 1841-55 & 1859: 2,078 tons of 6.5% copper ore.

Tretoil & Messar: 1859 & 1860: 100 tons of 5.75% copper ore, 19 tons of black tin, and 156 tons of zinc ore.

Tregullan: 1842-44: 1,163 tons of 6.25% copper ore and 7,910 tons of iron ore; 1852-54: 12 tons of lead ore.

Lanivet Consols: 1844-1845: 481 tons of 2.5% copper ore; 1865-67: 468 tons of iron ore, 30 tons of pyrite.

The reference to churchite-(y) and danalite at Tretoil Mine are Kingsbury citations (1956 and 1961, respectively). Given the doubts about the provenance of other Kingsbury specimens (Ryback et al. 1998, 2001), further confirmation is required.
