1957 During the course of exploration for asbestos Canadian Johns Manville noted the occurrence of a zone of extensive talc carbonate alteration in a number of diamond drill holes in the vicinity of the present Penhorwood mine. Due to its extent, this alteration was note worthy compared to numerous other occurrences found elsewhere in the area but not specifically recorded in other reports. Subsequently, other occurrences were inferred from magnetic surveys in the sixties but were not the target of exploration and were not pursued. 1973 Johns Manville started to develop the talc deposit. 1976 Johns Manville started production at the mine but this was terminated within a few months. 1978 Steetley Talc began mining the deposit. 1988 Talc de Luzenac carried out an exploration program prior to the purchase of the mine from Steetley Talc. 1992 Over the next two years, two additional exploration programs were carried out at the mine site.
