## RENISON EXPANSION PROJECT (RENTAILS) 

The Renison Expansion Project's (“Rentails”) objective is to reprocess and recover tin and copper from an estimated 18.95 Mt of tailings output from the historical processing of tin ores at the Renison Bell mine since 1965. The tailings have an average grade of 0.44% Tin and 0.20% Copper and represent one of the largest single resources of tin available in Australia today. 

Metals X completed a Definitive Feasibility Study into mining and re- processing of tailings for the recovery of tin and copper at Rentails in 2009. Financial outcomes estimated an average total cash cost of production of $11,875 per tonne of tin after copper credits, assuming a copper price of A$6,250 (current copper price A$8,300). 

Capital costs were estimated to be AUD$ 194 million +/- 15%. The study outcomes demonstrate that it remains exposed to upside from tin and copper prices . 

The proposed process route uses proven technology and has developed a robust circuit for the recovery of both tin and copper. In addition, the project would allow for the treatment of other tin sulphide (stannite) ore bodies within the region, which are not currently viable under conventional tin processing routes, as they require tin fuming. 

The Rentails flowsheet comprises the reclaiming of tailings from the historical dams at a rate of 2Mt per annum, producing approximately 5,300t of tin and 2,000t of copper in concentrate per annum. The tailings ore is finely ground to increase the liberation of the tin bearing minerals before removing the gangue sulphides by flotation. The sulphide flotation tails which contain the fine tin is then processed through classification, gravity recovery and tin flotation circuits. Flotation produces a 10% tin concentrate that will be smelted to produce a tin fume product assaying in excess of 68% tin. A by-product from the fuming process will be a saleable copper matte assaying 70% copper. 

Metals X is currently working with its BMTJV partners to validate the feasibility study in preparation to committing to the project development.
