This mining project proposes the exploitation of 120 tonnes of gold and 100,000 tonnes of copper in huge open pits. Rovina could thus become the largest mining operation in Romania, the size of the two open pits – 500 and 600 m diameter respectively and depth between 300 and 400 m – exceeding in size even the Rosia Montana project.

The principal gold minerals that affect the processing of gold ores are native gold, electrum, AuAg tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the AuAg tellurides, and very finegrained .
