Large spread of dumps and two engine houses. Adits in cliffs.
Tristramite was first discovered in the course of X-ray diffraction examination of radioactive material collected from south-west England by staff of the former Atomic Energy Division of the Geological Survey and Museum of Great Britain (now Institute of Geological Sciences).
Although tristramite has been identified in samples from dumps at several old copper and/or tin mines in Cornwall, including Trequeen, Wheal Alice, Wheal Buller, Wheal Damsel, and Wheal Providence, the best specimens to date come from Wheal Trewavas, where it occurs as a fine-grained aggregate and as coarser-grained infillings occupying fine fractures and cavities.
The data used to describe Tristramite were obtained from material from Wheal Trewavas.
