With demand for tin ever outstripping supply among dwindling global reserves, new discoveries by Trafford Resources will be a boon for the Australian company.
Widespread mineralisation has been discovered at on South Australia’s Eyre Peninsula, with four new deposits in the Wilcherry Hill Project area announced by Trafford, in addition to the existing Zealous deposit, leading the company to declare the area a new “tin province”.
The new deposits are Weednanna, Telephone Dam, Ultima Dam West and Oxy’s Bore.
So far Trafford has only assayed 7 per cent of samples taken, 5,400 out of the total of 80,000 samples.
Drilling has been undertaken both with reverse circulation and diamond.
There are a number of historic drill holes in Wilcherry Hill, going back to the early 80s, but most of the exploration work either didn’t test for tin or did not use correct assay techniques for the coase grained casserite, or tin oxide.
The Wilcherry Hill tenements cover an area of 2700 square kilometres, underlain by the Hiltaba Granites which have previously been identified as a potential source of tin mineralisation, thanks to the combination of granite with extensive reactive carbonates.
The majority of mineralisation is close to the surface, with assay results showing 3m @ 0.89 per cent at Telephone Dam, 1m @ 0.49 per cent at Oxy’s Bore and 6m @ 0.50 per cent at Weednanna.
Last year Trafford reported that drilling at Zealous had uncovered intersections of high grade tin, with Casserite as the prevalent mineral, as well as lead, zinc and uranium.
Zealous has registered 7m @ 3.28 per cent.
Tin is one of the most expensive metal commodities worldwide, with current cash prices quoted on the London Metals Exchange at US$23,020 per tonne.
