Thundelarra uses aircore drilling to generate further gold targets at Garden Gully

The program is designed to penetrate the surface cover to identify meaningful geochemical profiles.

Drilling at Garden Gully
Thundelarra’s exploration methods have been successful to date at the gold project

Thundelarra Ltd (ASX:THX) is undertaking aircore drilling at the Garden Gully Gold Project in Western Australia to test for near-surface extensions of mineralised targets.

The aircore program, which includes narrow diameter hammer drilling, is designed to penetrate the surface cover to generate more meaningful geochemical profiles.

These can then be used by Thundelarra to establish targets for follow-up deeper reverse circulation drilling.

This process has been successful in the past, including identification of the Lydia and Crown Prince prospects.

The company is awaiting a reverse circulation (RC) rig to test the Crown Prince follow-up targets with a diamond rig to then drill diamond tails as warranted.

Discovery of new prospects at Garden Gully resulted from an initial shallow scout drilling program in 2016.

There were 11 prospects identified for follow-up, a number of which were unknown.

Structural trends delineated

Subsequent testing has delineated structural trends along which the gold-bearing zones are located.

The possibility that repetitions of these zones may be present in areas previously untested is the reason for the aircore program.

It is believed that the varying thickness of the cover underlain by some areas of hard sub-surface, has contributed to the failure of soil geochemistry surveys to locate underlying primary mineralised structures.

First drilling at Crown Prince in late 2017 demonstrated that high-grade mineralisation is present at least 130 metres down plunge below the base of known mineralisation.

Results from more than 26,000 metres drilled in 141 RC and diamond drill holes since mid-2016 continue to support the possible existence of a large mineralised system at depth.

Thundelarra believes this may act as a single source for mineralisation identified so far at the various prospects.

Understanding of mineralisation is growing

Understanding of the controls on mineralisation is growing and improving with each work program.

The company considers that Garden Gully results to date are an unqualified success.

They continue to demonstrate that the project holds the potential for a significant new body of gold mineralisation in a proven gold province around Meekatharra.
