Constructive Dialogue: Copper M&A the Cupboard is Nearly Bare, page-29

Yep - important to see which variables have improved and which ones haven't.

Pit wall angles are assumptions only, but if too conservative they increase the strip ratio above what could be achievable and doom the project, if they are too aggressive/optimistic with their pit walls then the low grade and marginal economics potentially oom the project with any even a trivial wall failure.

Copper prices - pretty important variable - needs to be higher
Gold prices - AUD gold price has improved since the earlier feasibilities
Cobalt prices - pretty trivial amount and cost of Co always seems to be overwhelmed by the capital cost to extract the metal, unless it reports to copper sulfide cons its probably more of a nuisance than anything

Exchange Rates - have possibly moved a little in the projects favour, diesel costs pretty stable.
