"The overall net smelter return (NSR) for the three concentrates, including the silver and gold precious metals contributions, is expected to total more than $270 million at the forecast metal prices used for the base case models."
You will note that since then Gold has moved from their base case of $1275 per oz to almost $2000/oz.
Also the other base metals have moved up plus they now have a mineable resource some 5 x larger.
So I will spell this out again. 270 x 5 x a bit more = what???
billion dollars ish?
yep imo"
Im afraid this is incorrect. On a number of fronts.
Firstly, all base metal prices have not moved up. In the Study, zinc was $1.25/lb, now its about $1.08. Lead was $1.00, now its $0.82. Coppers gone up from $2.50 to $3, and silvers up from $17.5/oz to $24.
However, unfortunately, zinc is the largest Net Smelter Revenue (NSR) in the project, especially dominant in the early years, and combined with lead, which has also gone down - is around half the total revenue. Gold, which has gone up the most, is unfortunately the smallest of the 5 metals in terms of NSR within the mine resources. So overall, when you look at the total package of metals - the current prices over the overall metal package are almost exactly the same as the 2017 Scoping Study.
And then furthermore, and more importantly, this oft repeated nonsense about a 5x increase in the assets. Let me clarify. There is a (nearly) 5x increase in the quantity of ore they plan to mine, from 2.1 million tonnes to 10 million tonnes. This is because of two factors - firstly they are now including "inferred resources" in the mine plan, which is not permissible for a PFS but it is at a PEA level. And they secondly they are reducing the "cut off grade" - this will lower the grade of the ore they mine. This is because they are including more low grade ore in the resource. They have not "magicked up" an additional 8 million tonnes of ore without doing any more exploration. They are simply planning to mine more of the deposit than they were before.
So, to explain what this means precisely in practise - the 2.1 million tonne indicated resource was at around 4.1% zinc, 2.2% lead, 0.6% copper, 46g/t silver and 0.5g/t gold. ($130 NSR / tonne)
The 10 million tonnes ind+inf resource would be at around 2.2% zinc, 1.2% lead, 0.8% copper, 24g/t silver and 0.3g/t gold. ($80 metal value / tonne)
You'll also notice that most of the grades have almost halved, except the copper has gone up slightly, this is due to the inclusion of the copper rich Northern Copper zone, Garth Daniel and Deep Engine zone which are all inferred resources and were thus not in the 2.1 million tonnes.
Overall, the effect is that the 10 million tonnes contains around 3x as much total metal value (at current prices) as the 2.1 million tonnes did in the original mine plan, not 5x. Net Smelter Revenues will be around $800m.
