The Lake Rebecca Gold Project is immediately along strike of Apollo Consolidated Limited’s (ASX:AOP) 1.1-million-ounce Rebecca Gold Project and about 150 kilometres ENE of Kalgoorlie.
Bulletin’s drilling targeted fold structures and strike extensions of a 2.4-kilometre-long gold trend identified in earlier lake drilling.
In addition, it also targeted a structurally complex thrust fault zone along a major north-south structure to the east.
All significant mineralisation in the Lake Rebecca area appears to have a close association with this folding or a structural event.
Near-surface gold anomalism
Bulletin’s drilling program was designed to test for anomalous gold within regolith or weathered rock above basement rocks.
This near-surface gold anomalism may be indicative of potential gold mineralisation at depth.
Notably, a similar near-surface gold anomalism above AOP’s Rebecca deposit led to the discovery of the Rebecca gold system.
Samples sent for testing
Basement rock types intersected were granodiorite, tonalite, ultramafics and amphibolite.
These lithologies are the same as those seen further south and in drilling along the Rebecca trend to the west.
The average depth to the basement was 41 metres with the overlying regolith comprising transported cover averaging 28 metres thickness and 13 metres of weathered saprolite.
All samples have been sent to the laboratory in Kalgoorlie with results expected to be returned in August.
