Ann: Investor Presentation , page-11

There's only an answer available to your questions on slide 8– "is the entire product sold into the offtake and what are the general terms. What was the actual grade exported?"
----
"All product produced by WDR in first 5 years is pre-sold to Noble at prevailing Platts spot price at the time" - previous investor presos

"WDR has been able to export 276,999 tonnes at a grade of circa 60.2% Fe" - page 6 of the quarterly (circa! to the decimal place)
----

The rest of your questions I agree are valid ones to ask!
They don't appear to have a defined reserve, however the resource would last 10 years at least (that's not much comfort!)
