Breaker Resources NL (ASX: BRB) has received strong drilling results highlighting the potential for a significant gold discovery at the Kopai Prospect, situated 3km north of the 1MozBombora gold deposit within the 100%-owned Lake Roe Project in the Western Australian gold fields.
Executive Chairman, Tom Sanders, said results received to date from the first 32 holes in a 60 hole programme indicate the potential for Kopai to be a significant new gold discovery, with highlights including:
- 4m @ 4.54g/t Au from 84m within 9m @ 2.90g/t to end-of-hole (ends in mineralisation);
- 4m @ 2.68g/t Au from 20m within 8m @ 1.68g/t Au;
- 4m @ 2.53g/t Au from 20m within 8m @ 1.63g/t Au; and
- 4m @ 0.98g/t Au from 108m.
Drilling to date indicates the mineralised zone extends for at least 600m of strike, and remains open and sparsely drilled.
The mineralisation is located in high-iron mafic host rocks, and is associated with quartz veining and silica-albite-biotite-carbonate-sulphide alteration (similar to Bombora). Transported lake sediment over the zone is generally <5m thick.
Results are pending for a further 28 RC drill holes targeting a potential link between the Kopai Prospect and the Crescent Prospect, situated 1km to the south, which hosts a 350m-long zone of continuous shallow gold mineralisation (which is not in the Bombora Resource).
Follow-up drilling is being planned at Kopai, and will include shallow diamond drilling to obtain crucial early information on the host rocks and mineralised structures.
Mr Sanders said the strong results at the Kopai Prospect reinforce Breaker’s belief that Lake Roe is a significant new gold camp, centred on the 1MozBombora deposit, which itself continues to expand at depth.
“The results also continue to repeat the pattern of low-level oxide gold, and pathfinder anomalism, providing a reliable vector to primary mineralisation – a pattern seen at Bombora, Crescent, Claypan, and now Kopai.”
Reconnaissance drilling is now underway testing a 3,200m x 500m area of oxide gold anomalism, termed the Carbineer Prospect, located immediately east of the Bombora deposit.
The anomaly was defined by very wide-spaced (400-600m x 80m), sterilisation-focused aircore drilling during 2019, and is broadly coincident with the sheared western margin of the Swan Lake Syenite. There is no existing RC or diamond drilling into this anomaly.
