The Taronga Tin Project is the Company’s flagship project with a Mineral Resource (JORC 2012) containing over 57,000t of contained tin, making it one of the largest undeveloped hard-rock tin projects globally.

The Taronga Tin Project is located approximately 7km NW of Emmaville (northern New South Wales) within the Company’s wholly owned exploration license EL8407. Emmaville is a historic tin field with over 88,000t of contained tin having been produced since the 1870s. Previous owners BHP and Newmont  undertook extensive exploration at the project during the 1930-50’s and 1970-80s respectively.

The Taronga Tin Project comprises two major zones of quartz-cassiterite, sheeted vein-style mineralisation. The Northern Zone accounts for approximately 70 percent of the total Mineral Resource (27Mt @ 0.15%Sn for 40,100t contained tin) and is open at depth. The Southern Zone (9.3Mt @ 0.19%Sn for 17,100t contained tin) comprises a very coarse cassiterite demonstrating superior metallurgical properties plus contains higher tin, copper and silver grades. 

In 2014 the Company completed a Pre-Feasibility Study on the Taronga Tin Project demonstrating the technical and economic viability of the project. The study was based on 2.5Mtpa open pit operation over a nine year Life of Mine. Ore would be treated at site using dense medium, gravity and flotation to produce a final concentrate for sale overseas. The Pre-Feasibility Study generated a base case NPV(8%) of AU$63.15M. The Pre-Feasibility Study also identified a number of areas of potential project upside, including feed grade, tin recovery and by-product credits that have the capacity to increase the value of the project substantially.

In 2015 the Company announced it would commence a Stage 1 Development comprising a 340,000t trial mine within the Northern Zone Ore Reserves and pilot processing plant. The Company is currently progressing necessary approvals to undertake the trial mine. Recent metallurgical test work supporting the Stage 1 Development indicates positive concentrate grade, tin recovery and block model reconciliation Link to ASX announcement

The Company also considers that Taronga may be prospective for the specialty metal rubidium (Rb) based on anomalous rubidium results of up to 920ppm from previous drill hole results. The global consumption of rubidium is currently limited but its photo-emissive properties make it ideal for motion sensor devices and photoelectric cells (solar panels).  Rubidium is a high value metal with a current reported priceof US$1,472/100gm. Rubidium is mostly recovered as a by-product from the extraction of cesium and lithium and global resources are estimated at 80,000 tonnes of which 15 percent is in Canada and 75 percent in Africa.
