Ann: Coal Quality results from Mammoth seam at Cooroorah Project, page-6

Lets wait and see what the JT Boyd Concept study says wrt economics before getting too excited.
The capex burden on the project with drifts and shaft to 300+m will be significant.
Uneconomic coal is still uneconomic coal regardless of it's yield and quality.
And bear in mind that the area of the Mammoth seam;
1. is restricted in to the east of the main fault,
2. forms only 37 Mt (24%) of the total resource of 154 Mt,
3. with the seam thickness of 3.7 to 4.5m they may not be able to recover full seam section with conventional bord and pillar.
