The Taronga tin project lies in the New England region of northern New South Wales. The Taronga tin deposit is one of the largest undeveloped hard-rock tin deposits in the world. It ranks as the second largest tin deposit in Australia, on the basis of published information about mineral resources and previous estimates of mineralisation.
The deposit was first subject to serious evaluation by Newmont Holdings, amoung others (Newmont Joint Venture), between 1978 and 1984. During this six-year period more than 350 diamond core and percussion drill holes aggregating about 33,000 metres were drilled. Bulk sampling from 3000 tonnes of material was excavated from 1.8m by 1.2m adits at three locations on the deposit, and metallurgical, mining and engineering studies were carried out. These investigations culminated in a feasibility study based on a geo-statistically generated resource estimate of an aggregate tonnage of 37,589,000t of tin-mineralised material, at an overall grade of 0.153 per cent tin. The estimated contained tonnage of tin metal was for more than 57,000t.
Successful exploitation of the Taronga tin deposit has been greatly enhanced by the recent improvement in the price of tin metal. It would also be strongly improved by the discovery of higher-grade material at depth.
