The coordinates are those of Hazard shaft. There is no dump however, that can be specifically related to these workings. The minerals listed are those reported from the Hazard Section of Botallack Mine.

Material originally listed as Heulandite from Hazard is probably Clinoptilolite-Ca - See J. Russell Soc. 2006 p 68
