and what about chromite? PURs CEO also highlighted the chromite results from historical drilling (Ablett) in the radio interview last year in Dec. If Cal East is indeed not a PGE system, do the cromite results still make sense then? Or do the chromite results really hint at PGEs specifically? Also Scarpa highlighted the relevance of chromite for PGE prospectivity (see below). at the end of the day, it seems to be that the high chromite results in the historical drilling (together with Ni and Cu etc) really triggered interest re: PGE. Do we know whether CVV ever found high chromite?

"Geology - is chromite as a signature
Firstly need to understand what geological system/setting you are dealing with. Deposits where PGEs are evident can differ is my point - here are some of the systems as per https://pubs.usgs.gov/pp/1802/n/pp1802n.pdf
In the CHN of 23 March 2020 they state the following around what they think is there without categorising it clearly IMO: "large layered ultramafic-mafic intrusion is very exciting, as it draws potential parallels with other large-scale nickel-copper-PGE sulphide discoveries worldwide". In other words Julimar is a Magmatic Deposit - most likely Reef Type deposit IMO (refer N-12 of above link).
On the issue of chromite, all I will say is given the Julimar discovery, people would be happy in seeing it btw in the soil samples especially with nickel/copper specks LOL, which, in part, is the basis of a previous discussion in another stock. Chromite in itself doesn't mean you have a viable resource or what you think might be there orelse where chromite is everyone would think Bob's Your Uncle and start drilling blowing cash because chromite might be an indicator of rock type but not the embedded (nor extent of) mineralisation in the rock itself per se IMO.https://www.pitt.edu/~cejones/GeoImages/2IgneousRocks/IgneousCompositions.html
Olivine and Pyroxene is essentially within your ultramafic rock and Plagioclase and Pyroxene is within your mafic rock. Yes, chromite is commonly associated with olivine btw, just to be clear, (but chromite is also associated with a few other things, including certain metamorphic rocks, btw so just because you have chromite specks in say soil samples it is not indicative of what is below, but obviously the area having defined mafic/ultramafic rock types (which are igneous rock types) might give you more confidence to drill now hence why I have taken a punt here).
You can also find chromite as a layer, where concentrations are large, in some layered ultramafic intrusions btw as per pics you often see with the Bushveld system for example btw - infact this complex contains a hell of a lot of chromite btw - https://en.wikipedia.org/wiki/Bushveld_Igneous_Complex) - https://en.wikipedia.org/wiki/Chromite (just use links if need help). The Bushveld complex has some layers that are 90% Chromite - https://en.wikipedia.org/wiki/Pyroxenite"
