DARTMOOR DIAMOND MINE
Steve Grigg and Frank Collinson
This post summarises an exploration to Jack Cloke’s Prospect at Wapsworthy, where he is alleged to have found Zircons (fake diamonds). This exploration was inspired by the P.H.G.Richardson book entitled “Mines of Dartmoor and the Tamar Valley, after 1913”, which devotes a chapter (1) to this venture. The prospect at Wapsworthy, in the parish of Peter Tavy, by Jack and his brother Frank was in search of Zircon and Titanium and took place in some old tinners spoil heaps. This prospect is assumed to have been worked in 1920’s sometime after Jack had been part of the copper precipitating at Gawton Mine in the Tamar Valley. There appears to be only one public access gate and route to the site, which I have added information on to this post.
Zircon silicate, ZrSiO4, a principle source of zirconium is used in the nuclear industry. Transparent varieties are used as gemstones.
