I noticed that ROC were "upfront" in their Cliffhead announcement the other day and actually put an estimate on income, HDR had the opportunity to do the same on Chinguetti production but did not, these are the things that prompt potential buyers.
The fact that production is being increased over a number of weeks is not an excuse IMHO, a sliding chart would suffice.
