The Minerals Security Partnership, a coalition of 14 nations and the European Commission, will unveil a new financing network at an event in New York on Monday as they try to ramp up international collaboration and pledge financial support for a huge nickel project in Tanzania, backed by mining company BHP.

A joint statement due to be published on the margins of the UN general assembly says the network will “strengthen co-operation and promote information exchange and co-financing”. It lists 10 critical minerals projects that have already attracted support from MSP partner governments.

Representatives of BlackRock, Goldman Sachs, Citigroup, Rio Tinto and Anglo American are scheduled to attend the meeting, amid a push to attract private investors and miners to invest further in the sector.
