Ann: Citadel Project Exploration Results, page-55

Thanks @scalper for posting vid, it's greatly appreciated

A lot of info on Winu that I didn't know beforehand is shown in the presentation. The big thing that stands out to me is the geology of Winu. The gold and copper at Winu are 2 different systems, in the east-west gold trend there's no copper, so a big chunk of the deposit which hosts the gold mineralisation doesn't have copper accompanying it.

Also, the majority of the copper resource at Winu is at depth.

So I can see why Calibre/Magnum presents a good option and mining solution for RIO, due to the deposit style of Winu. The shallower higher-grade gold component at Calibre is 1.4Moz @ 1g/t which is more than double the gold grade @ Winu. Processing Calibre/Magnum ore could potentially add hundred/s of thousands of ounces of gold to Winu's initial output
