Not sure how you got $370M NPV for 60% from, but the lead price today is $0.98c/Lb vs $0.90/Lb in 2022 Update (both ~68c USD). Silver a bit less, but call it a 10% lift in AUD revenue which is material. Regardless of how things pan out, I'm super interested in the opex 2019 vs the 2022 update.

They dropped more expensive Room and Pillar mining for cheaper Long Hole Open Stope only over the thick, shallow dipping mineralisation which will help a bit, but still. Under ground inflation since 2019 in WA has been insane, consumables, transport, wages inflation has been insane. Also, I wonder if RAP was more expensive that LHOS back in 2019, it must have been in for a good reason... time will tell if that shallow dipping thick 'apron' mineralisation really works as assumed with LHOS in combo paste-fill.

My point is, there will probably be different opex costs and recoveries as there will be a different price deck over the LOM compared to the mine studies.
