The Cuprom Refinery and facility was recognised as a unique producer in Romania of electrolytically refined copper (99.99% Cu), having a production capacity of 40,000 tonnes/year and of fine gold and silver respectively (min. 99.96% Au/Ag), having a production capacity of 12 tonnes/year for gold, respectively 120 tonnes/year for silver.
Our precious metals project involves the metallurgical processing of secondary material and byproducts produced by the now-defunct Cuprom industrial site for the production of copper, gold and silver.
Terra Resources’ ownership (via Bitmine SRL) spans an area of approximately 20ha which comprises secondary material and precious metal refinables primed metallurgical processing. Preliminary assays range as follows: 0.12 to 5.94% Copper; 0.146 to 50(kg/mt) Silver; and 0.005 to 10.2(kg/mt) Gold.
In this regard, this project proposes to obtain precious metal products with commercial value from the secondary material, one of the more important material generated during pyrometallurgical copper extraction. This secondary material and precious metal contains large amounts of compounds with important commercial value.
The company’s technical partners, are currently conducting their own studies and test work to determine the appropriate and economic process of recovery of contained precious metal from the site.
