Brazilian Critical Minerals combines an experienced mining executive, recently appointed finance executive external company secretary and technical advisers. The current scope of two additional technical figures remains uncertain. Ema has advanced to a feasibility study and FEED but remains pre-production and without committed project finance or offtake in the October quarterly. An ongoing disputed shareholder claim, historical environmental notices and contractor safety proceedings are company-level matters with unresolved outcomes; none establishes individual misconduct.

Wetar produced copper but output subsequently weakened

Finders reported 23,160 tonnes of copper cathode and A$56.3m net profit in 2017, its first full year of output.
