Potential of Berkshire Valley Ni-Cu-PGE Project At SW Yilgarn Craton Margin

I am a long term LTR holder and now a TRT holder. My interest to the Julimar region has started after CHN's Julimar discovery and I was researching the Julimar-Moora region of South-west terrane of Yilgarn Craton for the last 9 months.

According to my research TRT's Berkshire Valley Ni-Cu-PGE project has very high potential or Geological Chance of Success (GCOS) IMO.

The high potential is coming from the geological settings. The main character of geological setting is about the "Layered Mafic and Ultramafic Intrusions" which can create very high grade deposits for Ni-Cu-PGE, V, Ti and gold of course.


HIGH PROSPECTIVITY ZONE

And the main prospective zone is being at a zone which has a certain proximity to the margins of Yilgarn Craton which is defined by the Darling Fault. (see the graphic map below)

According to my research the prospectivity for sulphide-related mineralisation (same for laterite deposits) starts at 15-20km easterly away from Darling Fault (western margins of Yilgarn Craton, which is also defined by the hills at the eastern part of Perth.

That is benig nearly proved by these projects;

1. CHN: Julimar project
2. LTR: Moora Project
3. CPN: Yarawindah Project

The map below was given on an LTR anns.



I modified LTR's map and added TRT tenements and marked the prospective zone (IMO).







The area has high potential for the tholeiitic intrusion-hosted Ni-Cu-PGE sulfide deposits according to GeoScience Australia (Gov.Dept)

There is one very important and interesting document prepared by Geoscience Australia (Gov. dept) in 2016. As far as I understand the info given in this document has been ignored by most of the resources companies. CHN's Tim Goyder and co has the info about it and they have already got Moora tenements for LTR in 2018. Then they got more for CHN and DEV.

"Potential for intrusion-hosted Ni-Cu-PGE sulfide deposits in Australia- A continental-scale analysis of mineral system prospectivity" by GeoScience Australia

This document was explaining (in 2016) that the region where CHN and LTR are exploring might be very prospective for Ni-Cu-PGE.

It’s all about the type of geology close to Yilgarn craton margins. The tholeiitic intrusion-hosted Ni-Cu-PGE sulfide deposits can be found in those areas similar to Noril’sk (Russia), Voisey’s Bay (Canada) and Jinchuan (China) deposits.

The problem is the regolith (or laterite) cover over those potential deposits. That regolith cover was also mentioned on announcements by LTR before.

The map below was showing "Mineral-systems-analysis--Potential-for-tholeiitic-intrusion-hosted-NiCu-PGE-sulfide-deposits"

As you can see the high potential area are marked in red where the legendary discovery Nova-Bollinger was made (by TRT's director Mark Bennett when he was running Sirius Res. in 2012) and Julimar discovery by CHN as well as other big discoveries in other regions.
