Ann: Positive Mining Study at Cooroorah, page-3

Interesting indeed.
1. Confirms a new development/infrastructure Bord & Pillar project wasn't economic as I had suggested previously.
2. Above result has forced BCB and its consultants to adopt higher risk longwall mining approach in Rangal Coal Measures. Kenmare (South Blackwater) almost buried their longwall on the lower seam, and there are 2 buried longwalls at Cook Colliery from 2 separate attempts at longwall production.
3. The economics will totally depend on whether the development advance and longwall retreat rates assumed by the consultants are reasonable in the Rangal Coal Measures (noting that both Cook and Kenmare are relevant benchmark operations), and the average length of the longwall panels also (equating to the number of longwall moves per annum required to deliver the target annual production). This information has not been provided in BCBs press release (in fact no real technical information nor the key assumptions have been provided in the BCB press release to support the assertion of positive economics).
