Abstract
Slightly over 30 years from the Buchim are exploited poor porphyry copper mineralizations. From calculated total ore reserves of around 120 Mt with 0.3% Cu and 0.3 g/t Au, calculated at the cut-off grade of 0.20% Cu, during last 33 years has been exploited 110 Mt of ore with an average copper concentration of 0.236%Cu and gold of 0.297 g/t Au and cut-off grade of 0.15% Cu. The present remaining exploitable ore reserves in the Buchim mine are around 40 Mt with 0.25% Cu and 0.245 g/t Au at cut-off grade of 0.15% Cu. The present economic parameters calculated at the Bunardzik ore body, as the newest ore body ready for exploitation have shown that minimal economic concentration of copper in the ore should be at least 0.2099% Cu, its service life should be approximately 4.5 years (calculated at Buchim’s annual production of 4Mt) and the value of the metal within it is approximatelly 289 millions US dollars. This is an information, which points out that these poor ore bodies within the Buchim mine undoubtely are providing profit with their exploitation.
