Hi Expart!
Thanks for sharing your parallel calculation for iridium and ruthenium content in the SLP 6E prill split. Given today's prices for the "minor" PGMs, your post really shows how lucky SLP is to be processing UG2 and not Merensky reef ore. (No, I don't think Terry foresaw the current situation all those years ago when he set up the Dumps Operations!)
Taking your numbers, they imply that if SLP hit their guidance of 70K 4E PGM ounces, that would equal production of almost exactly 95K of 6E PGM ounces.
Of these extra ounces 4,845 ounces would be iridium. And 20,140 would be ruthenium. These are in the same ballpark as Barna's numbers yesterday.
Spot price iridium today: $5,900 (up again). Spot price ruthenium today: $390 (up again).
So, if you annualise today's spot prices you get "extra" revenue of $28.6m from iridium and $7.9m from ruthenium = $36.5m total for the "by-products".
To give an idea of the revenue growth now coming from the by-products, using the average prices for calendar year 2020 and similar production, you get to (4,845 oz iridium x $1,622 average price = $7.9m) + (20,140 oz ruthenium x $264 average price = $5.3m) = $13.2m.
So, if you assume today's spot prices for the by-products will be this year's average prices, that makes an improvement in revenue of $23.3m! And remember, SLP calculate their AISC on a 4E basis, so these ounces come for "free" except for the smelting and refining charge (allow a conservative 20%) and profit taxes.
