P2 of Mr Connelly's report in the executive summary.....
"The project is based on processing 25 tph of copper cobalt ore."
Let's see 25t/h X 24 hrs/d X 365d/yr = 219,000t/yr at 100% availability.
80% availability = 175,200t/yr rounded to 175,000t/yr
Why 80% (estimated P16 of report) scheduled maintenance and unscheduled breakdowns/stoppages (hence why he mentions carrying spares).
You don't like the numbers in the report, I get it, but please don't dismiss them. They are not my numbers, they are in the Independent Experts report.
You re-read the report and quote where it states 250,000t/yr, I certainly can't find it.
Last years estimate from the company is irrelevant when an Independent Expert has stated something different!!
