Domeykite ?
Description: Arsenical copper pyrites (an old name for Domeykite) is recorded as having been found here by Phillips (1823). Elsewhere he notes that this mineral consists "of 40 per cent of copper, the remainder consisting of iron, arsenic and sulphur". Thus, the material was either impure or a mixture of different minerals and therefore, the occurrence has to be considered as questionable.

Fluorite
Habit: Cubes and cubo-octahedrons
Colour: Green
Description: A little known fact is that fluorite was apparently mined as smelting flux, although there are no production figures (W. Phillips, ca. 1805).
