Treliver Minerals Ltd (TML) is focussed on tin exploration and development in the county of Cornwall, UK. Cornwall has historically been a major tin producer, with an estimated 2.8 million tonnes of tin produced from the Bronze age (~2000BCE) up until the closure of the last mine, South Crofty, in 1998. Tin is associated with six granite intrusions that underlie the county and has been historically mined as either alluvial tin in river valleys or as narrow high grade (plus 1% Sn) lodes. However, it is known that broad low grade stockwork tin systems also exist, but their low grades mean that these were not exploited in the past. These are seen as excellent exploration targets and an analogy can be drawn to the re-working of halos to high grade gold lodes in the goldfields of Western Australia during the 1980s.
All mineral rights are privately owned in Cornwall and TML has an excellent network and database of these, putting it well ahead of the pack for acquiring additional projects.
