"why OMH has Low profitability"
Maybe you aren't able to understand financial reports? According to you, $116 million profit after tax for six months ended Dec2017 is low profitability. WOW, its more profit than the majority of companies in Australia. Why do you think OMH is now a $1 billion company?
You talk about GMC high grade Mn ore, maybe you should start reading GMC reports. GMC doesn't own a single mine nor a single Mn ore exploration permit. Everything depends on outside suppliers as GMC has no Mn resources whatsoever.
Nearly every ferro alloy smelter in the world owns their own Mn mine.
I will also correct you, Indian power prices are cheaper than Indonesia. Japan power prices are the same as Indonesia. That is why most alloy smelting in Japan has shifted to Sarawak in Malaysia, approx 5 x large steel manufacturers in Japan are major shareholders of the 3 x smelter companies at SCORE Sarawak.
