To me it just shows that brown coal looks like changing from an almost worthless commodity to something of appreciating value.
You don't go to the trouble of setting up companies in a sector unless you intend to make money from it.
It seems every second week a new tech or BC player pops up in Aus.
Brown coal is growing in credibility as a commodity and Mantle is well positioned to benefit from it IMO.
