Ghana's mining sector is dominated by gold. The country's government has been engaged in a diversification policy for several years, in order to benefit from the energy transition to exploit its lithium and graphite resources, two materials used in electric vehicles. The launch of an exploratory study in the second quarter is part of junior mining's objectives for 2023. According to an estimate in accordance with the 2004 JORC code, the Kambale project hosts 14.4 million tons containing 7.2% of graphitic carbon and 1.03 million tons of graphite.
