Ann: 2025 Unearthed Natural Resources Conference Presentation, page-14

Your question is simple but the answer is complex. Thats why I've included the announcement when they bought the mill.
https://announcements.asx.com.au/asxpdf/20240715/pdf/065kwtf3q9b7xd.pdf

A mill's tonnage depends on the hardness of the ore and the grind size ( fineness) of the material you need to grind down to get acceptable recovery (which in itself is a tradeoff of economic variable, namely gold price).

If one looks a the announcement, it indicates mill capacity is as 650,000 p.a., that's around 75 TPH.
But you'll be able to go faster on oxide (open pit) ore, both because the ore is softer and leaches easier).

I think in the schedules they have higher tonnages in earlier years and lower later. Note too, with recent drilling, we are coming up with more or in pit walls with potential to move those walls out.

I think the best way is to follow their schedules in the DFS (presso) and hope for the metallurgists to do what we try which is "flog it till you bog it". That will include optimising for grind size. often up to 20% more tonnes than initially projected.

All IMVHO.
