Redmoor, Cornwall: A Cornish Resource of Global Significance

The speaker will be Dr James Blight, a Senior Geologist at Cornwall Resources Ltd, responsible for resource modelling and interpretation, working closely with CRL’s independent resource consultant. His background is exploration geologist, with a PhD and 12 years industrial and field experience, including orogenic gold and VMS projects, project management generally, diamond and RC drilling, geochemical sampling (planning and execution), scientific interpretation of results, in-field logistics, health & safety leadership, and recruitment/mentoring of geological staff. Also exploration IT, including as project lead for introducing geological GIS to a large exploration department.

According to Dines (1956), Redmoor Mine was worked periodically from before 1858 to WW2. It first produced lead and silver then tin, copper, wolfram and arsenic. The old sett, adjacent to Kelly Bray (Callington) and just west of Kit Hill, contained several lodes and extended some ½km east-west and 300-400m north-south. It was prospected again in the early 1980's but work stopped in 1985 due to financial pressures. The CRL project is a new and exciting exploration which has produced consistently good results during their drilling program, confirming a high-grade Sn-W-Cu ore pattern with a latest estimated resource of 11.7 Mt @ 1.17 % Sn equivalent, making Redmoor the world's largest undeveloped underground tin-tungsten deposit by contained metal.

This will be a fascinating talk both for members and non-members, and of additional interest Dr Blight will be bringing along some drill-cores for examination and discussion.
