This is an interesting piece of research on nickel deposits.

These pages below are of particular interest, as they are similar to Desert Metals' Irrida, Innouendy nickel/copper sulphide projects, which sit on the edge of the Yilgarn Craton in WA.

The example below is of nickel deposits that sit on the edge of the Superior craton in Canada "example of control by the margin(edge of craton) of a lithospheric domain".

"Nickel sulphide deposits occur at lithospheric (surface rock) boundary zones because the geometry of the base of the lithosphere controls the degree of melting of mantle plumes."

This is how both Nova Bollinger and Julimar Nickel-Copper Sulphide & PGE deposits were formed on the edge of the Yilgarn Craton.

In exactly the same setting as Canada's Superior Craton above.

Similar volcanic events in the red text above ("Nickel sulphide deposits occur at lithospheric (surface rock) boundary zones because the geometry of the base of the lithosphere controls the degree of melting of mantle plumes.") in Canada, and in the Yilgarn at Challice Minings Julimar and Sirius Resources Nova Bollinger, are responsible for the creation of these conductors at Irrida, Innouendy (Narryer Terraine).

As well as an additional 6-12 conductors in their tenements on the edge of the Yilgarn Craton below, and why Dr Rob Stuart is targeting these areas.

You can see in Desert Metals' mineralisation model below, the volicanic intrusion (red arrows) squeezing on the edge of Yilgarn Craton, between the lithospheric rock. Exactly the same as above in Canada's most prolific nickel sulhide deposit region.









The nickel deposit research document goes on to highlight that these intrusions form massive nickel-copper sulphide deposits at the bottom of magma chambers, due to their density as the sulphur enrichens these elements.

They pool at the bottom, creating a lense(s) like structure(s). Over time, these structures can be lifted into all sorts of angles by deformations in the earth, which may explain why these lenses at Irrida and Innouendy have a steep downward slope, similar to the deeper lenses at Challice Mining's Julimar Nickel/Copper/PGE deposit.
