Breaker Resources NL has reported the discovery of multiple high-grade lodes at the Bombora deposit at its Lake Roe Project which is located 100 kilometres (km) east of Kalgoorlie in Western Australia.
The Lake Roe Project is located between two large gold deposits, the 3.5 million ounce (Moz) Carosue Dam mine and the 0.9Moz Karonie gold deposit.
The latest drilling results extend the known strike length of the high-grade mineralisation and materially enhance the depth potential below the northern part of the 1Moz open-pit Bombora Resource to 2 km.
Other lodes with similar strong visual characteristics were also intersected below the new high-grade lodes and in several other drill holes below the northern part of the open pit Resource (assays still pending according to Breaker).
The company outlines that significant results were received from holes testing both the north- and south-plunging elements of the Bombora lode system.
These arise from the (respective) intersection of the steep and north dipping ‘flat’ mineralised faults with the magnetite-rich parts of the quartz dolerite host rock.
Additionally, a 1.1 km-deep stratigraphic diamond drill hole in the southern part of the deposit delivered a Tura lode intercept of 9.7m at 1.57 grams per tonne gold (g/t Au) in the upper, less prospective part of the quartz dolerite after a 400m down-plunge step-out.
Breaker states that this result is “encouraging” and “complements previous high-grade intersections on the Tura, Daisy and newly coined Brigalow Mick steep lodes.”
Deep drill testing of the steep lodes is embryonic. Other reconnaissance drilling results in this report relate to the Claypan and Bombora South areas south of the Bombora deposit, where wide-spaced drilling returned up to 4m at 1.49g/t Au.
The company notes that this is significant given the wide-spaced nature of the drilling, and follow-up drilling is expected.
Breaker Executive Chairman, Tom Sanders, said the results provided more firm evidence of the strong potential to grow the 1Moz Resource at Bombora.
“Drilling outside the 3.2km-long 1Moz Bombora deposit has been limited in scope to date mainly due to an early strategic focus on establishing and de-risking a large, shallow open pit resource,” he detailed.“But given the scale of the greenfields gold system, we are now prioritising resource growth.”
Mr Sanders further commented that the company is now applying its understanding of the shallow gold mineralisation to find more gold.
“We are also about to drill for more shallow gold at places like the Kopai Prospect, which we are excited about,” he commented.
“Our early objective with the drilling is discovery to lay a solid foundation for ongoing resource growth and to unlock the full potential of the 9km-long gold system.”
Key drilling highlights:
Latest drilling intersects new sulphide lodes up to 630m below surface over a 2km strike length at the Bombora deposit within the Lake Roe Project near Kalgoorlie.
Strong preliminary results include:
- 1.85m at 12.94g/t Au from 442.5m in BBDD0092W1
- 2.5m at 11.25g/t Au from 585m in BBDD0092W1
- 2.46m at 14.01g/t Au from 479.54m in BBDD0092W2
Assay results are pending for four diamond drill holes with eight strong visual lode intersections.
The results extend the known limits of the north-plunging gold lode system by 600m and demonstrate the strong potential to keep growing the 1Moz Bombora Resource.
The testing of south plunging lode extensions at depth was advanced with a 400m step-out intercept on the Tura lode of 9.7m @ 1.57g/t Au. The width of intersection is encouraging given it is in the upper, less prospective part of the quartz dolerite.
Diamond drilling ongoing with two rigs operating on 300m-spaced step-out lines.
RC drilling to commence this week at Kopai-Crescent zone 3km north of Bombora. This will be the first serious test of a 2km-long zone with several areas of shallow bedrock gold grading greater-than 1g/t Au.
