This is a group project but I am only asking to get my part done. This is about a fictional mining company. My role is the one of a financial director. I need to research the following mining companies:
Glencore
BHP Billiton
Rio Tinto
China Shenhua Energy
Anglo American PLC
Zijin Mining

to  draw ideas regarding:
Existing and most common sustainability challenges/pressures faced by the sector, using several tools, among which their Materiality Matrices, and performing evaluation tests using tools such as Mkinseys 7S, for example. Everything else you need to know is explained in the document attached.
