This came out on April 26, 2018. It is in French. Here is the key paragraph translated:
"A feasibility study was carried out on the Kola project and would already be 81%. It concerns the infrastructure, the operation, the ore transport, the processing plant and the marine export of the product. This study will be ready in 2019 and Sintoukola intends to produce 2 million tonnes of potash per year. The French Public Investment Bank will guarantee the construction of the mine. The Mengo mine will be operated by Chinese Evergreen"
The Mengo mine is the one owned by Magindustries (MAAFF). Evergreen owns Magindustries. The last news we got, which came in April of 2017, said that production would begin in 2018. It looks like it has been pushed to 2019.
