The evidence is there around the world, no companies whom have become conglomerates and survived/thrived through the years especially mining companies are single commodity companies.
BHP/RIO, even FMG I would say a fairly young company is diversifying into areas other than iron ore, which at this stage looks to be hydrogen energy.
Westfarmers which used (still have?) to have coal mining, has now diversified into everything.
WHC management themselves have recognised the phasing out of thermal coal moving forward and have executed plans to diversify into met coal.
Judging by previous actions I am impressed by our managements actions, they are bold with their acquisitions and conservative with their capital expenditure when required as highlighted through cessation of buy backs, reduced dividends and partial selloff of Blackwater to reduce debt.
Bottomline is I am hoping WHC to become a forever stock with stable market rate dividend yields and higher than average industrial capital compounded growth, is that too much to ask, lol.
