Murgoo

The Murgoo Project, comprising two exploration licenses (E59/1448 and E59/1556) covering almost 260 sq kms, is located between two gold bearing greenstone belts: the Yalgoo Belt to the southwest and the Dalgaranga Belt to the northeast. The northernmost part of the tenement area includes greenstone lithologies, where greatest potential for gold mineralisation exists. Elsewhere the tenement is largely underlain by granite or other intrusive rocks.
A strong magnetic response in the northeast portion of the western tenement shows a dilated linear folded pattern (similar to that for BIF). These magnetic linears occur beneath cover and take the form of repeated arcuate folds and separated fold limbs around a central circular magnetic anomaly.

This circular anomaly is coincident with an area barren of all vegetation. While there are several possible explanations, one is the presence of a significant buried sulphide body with base metal potential. Initially, a ground EM survey is proposed to confirm the presence of shallow conductive body (Figure 6 – Target 6).

A number of gold targets have also been identified around this anomaly (Figure 6 – Targets 5a through 5d). The magnetic units adjacent to the anomaly may represent ultramafics, mafics or BIFs and are more likely to be mineralised in areas of maximum deformation. Whilst the magnetic units themselves may be mineralised in areas of deformation so too are the stress shadow positions that lie adjacent to the circular magnetic anomaly. Such positions may also act as trap sites for gold where ductile units are deformed around brittle units, and gold is deposited where space is created at the interface. Such forms of gold deposition and related deformation are common around and within large granite bodies (e.g. Granny Smith and Tarmoola) where stress shadow trap sites may host gold.

There is little or no previous exploration evident on-ground or from DoIR records in this area.
