Possible, but as the article mentions, the Mongolian part of the award carving up TT is to a Russian-Mongolian company, so Mongolian efforts to buy Mongolian would not have that clear of a way to do so. Also note that the article emphasizes the boom being fueled by mining, a fair part of which initially was with coal, and it mentions the coal demand from China.
I feel that signs for PCY will be if the power generation project continues to be fast tracked by the government. That aligns with the development and diversification objectives mentioned in the article. The increased metals mining to come will need power, as will continued development of the living styles of the population. There will be a huge availability of coal in Mongolia. Electricity ? Now that is something else.
What concern's me most about the Bloomberg article is the way it spoke of Erdenes TT - I had always just heard it referred to as the TT coal property, and I knew Erdene (tse ERD) took a big hit when the awards were finally announced excluding them, and they put out a PR about how it was not yet all said and done, but to see the property actually referred to that way. Makes one wonder what rules are being used.
