Treliver Farm was discovered by Billiton Exploration (UK) Ltd in 1982 following a regional stream sediment and soil sampling survey. Billiton partially drilled the property but walked away from tin exploration after a calamitous drop in tin prices associated with the collapse of the International Tin Council in 1985.

Exploration Activities

Treliver has drilled 6,000m in 58 holes along 700m of strike and has defined a JORC compliant inferred resource estimate of 4.5Mt @ 0.15% Sn in the top 100m for 6,700 mt contained tin.

Mineralization starts from surface and is open-pittable in structures within calc-silicate horizons, typically 30m to 50m wide. A higher grade core is often encountered with a best intercept of 18m @ 0.95% from 47m. Soil geochemical anomalies are indicative of an overall strike length of up to 1,500m. The orebody is heavily weathered and is mainly free digging with minimal drill-and-blast likely to be required. Tin occurs only as relatively coarse cassiterite amenable to simple gravity extraction techniques. The source granite is known to be at +450m depth and there is very good potential for feeder structures to exist to this depth and beyond.


The site is served by exceptional infrastructure - water, major road, rail, power station, regional airport and skilled workforce are all visible from the site. Treliver Farm is approximately 1 mile from the very large kaolin mining operations of Imerys. Synergies may exist with the potential for waste and tailings disposal in an old disused china clay pit.

I am extremely pleased that we have been able to report resource estimates for the Tellerhauser project in accordance with the 2012 JORC Code & Guidelines. This resource now sits as one of the largest undeveloped tin deposits in the world and also boasts one of the highest tin equivalent grades. Tellerhauser is also the largest and highest grade indium deposit reported in accordance with 2012 JORC guidelines in the world. Our aim now is to increase the category of estimation by collecting underground samples to confirm the previous assaying.
