help with coal quality, page-67

Attractive Deposit with Significant Exploration Potential: The Nuurst licence is a large exploration licence covering known coal mineralization on a larger coal
deposit (Tsaidam). Following a review of available historical data, Nuurst has an exploration target of:
50 to 100 million tonnes thermal coal, Calorific value range
Qdaf 6200 to 6800 kcal/kg

Management had been upfront with quality. So i thought they had been honest and did not fudge the figures all this time. We got carried away and expect too much.
