The NC mining partners are:
1) Societe des Mines de la Tontouta ('SMT')
https://www.smt.nc/
2) Societe Miniere Georges Montagnat SARL
(no website)
For instance, the SMT's operations are located below, with Goro's position marked for reference. There's little chance of disruption if Goro is blockaded again.
Referring to the comment about lateriate grade, we do need decent grade, so any old scrap probably wouldn't do.
