The chromium ore reserves of the mine are split into two categories above and below Level +1560. The proven ore reserves located above the Level +1560 amount to 730,000 tonnes of ore grading 38% chromium metal.[1] The proven ore reserves located below the Level +1560 are currently not estimated or calculated but are expected to be grading 45% chromium metal.[1] The mine was privatised in 1999.
