Argoz, the cost would likely be more like $35-40 million based on discussions a year or so ago and would require the completion of the new larger ramp that was started last year but has been on hold. I think there was a mention of this ramp in either a press release or the financials. This ramp would provide a new and much larger access to level 19 and below, if I recall correctly.
We should get a good idea from the upcoming preliminary economic study, scoping study. At one time the 5000 tpd mill was considered about $100 million expenditure, again from memory a year or so ago.
There is some minor info presented on this in the slide ECU slide show.
