Republic of Congo’s Massive Good Grade Potash Deposits Could Make them Major Global Miner

Mineweb reported that the Republic of Congo (ROC) is being touted as having potential to become one of the world’s biggest potash miners over the next decade.

As quoted in the market report:

The Congo evaporitic sequence contains the country’s world-class potash resources in the form of carnallite and sylvite. The salt sequence is reportedly some 500 m thick, although it does thin out at the edges of the deposits.  It is very consistent.  According to Elemental Minerals, one of the companies interested in developing the deposits, the evaporite sequence of the Congolese coastal basin consists of essentially flat-lying, but locally undulating salt layers of interbedded halite (NaCl), and other higher salts such as sylvite (KCl), carnallite (KMgCl₃·6H₂O), bischofite (MgCl₂·6(H₂O)), and minor anhydrite (CaSO₄) and dolomite (CaMg(CO₃)₂) beds that extend from the onshore Congo Basin north and south to sedimentary basins in adjacent West-African countries, as well as west into offshore regions. Overall there are thought to be billions of tonnes of potash which could be mined by conventional methods and/or by solution mining.
