RE: What is the total debt?7 Aug 2018 17:59
Richam,
I think the early 2015 reserve report quoted in the order of 35Mt ore. Back of a fag packet, I expect around 2Mt per year may have been fed into the plant over the last 3 years of operation (on average say), so take off about 6Mt which leaves 29Mt.
However, I'm guessing that the 2015 reserves were calculated based upon feasibility study cost assumptions, due to lack of anything more concrete pre-production, and, as stated therein, at metal prices similar to a those of a couple of months ago. So it would be reasonable to conclude that costs have been / are somewhat higher than those quoted in the feasibility report. As such, some of that reserve stated back in 2015, may now be non-viable cost wise.
Further, the ore has been stated to be more complex than anticipated in the feasibility which I presume has added to the woes of the plant and possibly metal yields.
How much of that remaining estimate of 29Mt will have to be disregarded due to economics, and in order to provide optimal feed for the plant, is anybodies guess.
If we assume that the plant keeps improving, as stated, and ~3.0 to 3.5Mt goes through each year from now on, I calculate that would give a Max life of 8 - 9 years. Somewhat less if the above stated economic and optimal ore feed are taken into account. Even if costs come under control, there's still the metal prices to consider.
I presume the pre-processing of ore is aimed at improving said ore feed and maximising life. However, surely pre-processing and this crusher trial will incur additional cost (compared with mining direct to the plant) thus making costs even higher ? I guess Wolf see it as a worthwhile exercise. I'm wondering how they are going to keep a lid on total operational costs going forward.
Just my thoughts.
