Interesting Spec, you are very bullish mate.
I must admit I have never been more bullish myself.

Sly Fox, West Winds and Four Pillars are looking like they COULD be large enough SCALE to supply bulk underground tons for years to come.
This has pushed my year 3 and beyond production estimate up from (130 - 160k) oz to (170k to 200k) oz.

NN 600k oz * 6gt = 108,810oz recovered @ 94%
The rest 900k oz * 2.8gt ave = 76,167oz recovered @ 94%
Total 1.5mtpa Head grade 4.1gt total ounces produced 184,977.
Using your estimates that is a current margin of approx $2,200 per ounce.
185,000oz * $2,200 margin = 407 million pre-tax cash

That is crazy cash generation. I STILL prefer to be a little more conservative with my AIC calculations ($1,800 per oz).

185,000oz * $1,900 margin = 351 million pre-tax cash

Still insane money

This is why I didn't care about Sly Fox not being high grade. Doubling Sly's potential tonnage OUTPUT will make a huge difference to LOM production profile.

Dream scenario's 1 or 2.
Both 10 year LOM.

Option 1 (preferred) = scaled back mill filled with enough underground ore to process on average 1.5mtpa per annum.
Option 2 = run mill at nameplate and find more open pittable base load resources to complement underground operations.

The table below shows grade truly is King!!!
