Intrusive rock types confirmed at NSW gold project

Our junior exploration Investment TechGen Metals (ASX: TG1) today provided an update on petrology results from its John Bull Gold Project in NSW.

The results from eight samples collected during soil sampling confirmed intrusive rock types in the project area. Importantly, this suggest that the host source could be an intrusive system as compared to the orogenic system that TG1 observed at the surface.

If this is the case — to be confirmed by follow up drilling next year — then TG1 could in fact have a very large gold system on its hands.

There are several features of the geology and mineralisation at the project that support TG1’s interpretation of a possible Intrusion Related Gold System (IRGS) style of mineralisation, and IRGS gold deposits are known to be present in the area.

This cross section shows the Intrusion Related Gold System Model (on left) and how gold mineralisation can occur in relation to an intrusive body. On the right is the interpreted position of the TG1’s project within that IRGS model.

Note, that this is only an interpretation of what the intrusion related system could look like at TG1’s project —  only through drilling will the company know if in fact this type of system exists.

While TG1 holds a portfolio of twenty-five exploration licences across five geological regions in WA and NSW, drilling at this NSW gold project was the #1 objective in our TG1 Investment Memo that we wanted to see achieved.

What’s next at TG1’s NSW gold project?

In the new year, TG1 wants to commence further field mapping at the project area. Planning and permitting is underway for a follow-up RC and diamond drilling program to test for depth extensions beneath recent RC drill intersections and also to undertake step out drill lines to both the north and south of recent drilling.
