Location, Access and Infrastructure
The Comet Gold Project comprises one exploration licence application, E20/908 covering 37.2 square kilometres, located approximately 115 km south southwest of Meekatharra and 20 km southeast of Cue. The project covers part of the Meekatharra to Mount Magnet Greenstone belt, located at the southern end of the Tuckabianna Shear Zone (Figure 1).

The project lies immediately to the north and along strike of the Comet gold mine, but has had very little modern exploration carried out within the licence area. Initial exploration by Newcrest Mining Ltd and Westgold Resources NL, during the mid-1990’s identified a mineralised gold trend in shallow RAB drilling to the north of the Comet mine. The RAB drilling returned a number of significant gold values over 1.4 km strike. A second zone of anomalous drilling lies approximately one kilometre to the east. RAB and limited RC drilling returned anomalous gold values.
Local Geology and Mineralisation
The historical Tuckabianna gold deposits that were mined in the late 1980s and early 1990s are hosted primarily in a banded iron formation (BIF) sequence. The shear zone has bene intruded by post tectonic granitoids, and separates the regional geology, east and west into two domains. Supracrustal sequences are exposed in an asymmetric syncline, including mafic to ultramafic volcanic sequences and associated banded iron formation to the east. To the west, there are the felsic Eelya complex and basalt and high-Mg basalt not associated with BIF.
A number of companies have explored the Comet project and the surrounding area for gold since the 1980s including Newcrest Mining Ltd (Newcrest), Westgold Resources NL (Westgold), Australmin Holdings Ltd (Australmin), Big Bell Gold Operations Pty Ltd (Big Bell), Westcoast Mining Ltd (Westcoast), Silver Lake Resources Ltd (Silver Lake) and Metals X Ltd (Metals X).
The most focused gold exploration within the current Comet project was undertaken by Newcrest Mining Ltd and Westgold Resources NL. Exploration by these companies during the mid-1990’s identified a mineralised gold trend in shallow RAB drilling to the north of the Comet mine and a second zone of anomalous RAB and RC drilling approximately one kilometre to the east. Most of the other companies who held tenure over parts of the current Comet project area, focused their exploration on other prospect areas outside the current tenure.
Exploration Potential and Planned Work
Once the Company’s application for tenure has been granted, exploration will include aircore drilling of the identified targets along the Comet mineralized trend and the eastern gold anomaly.
