A 2-metre interval at 14.17 g/t within a broader intersection of 11 metres at 5.66 g/t from 67 metres was the standout result.
Within the 11-metre intersection was another 3 metres at 9.44 g/t.
Planned open pit operation
The new results will be incorporated in a resource estimate for a planned open-pit operation at Trident West.
It will be a maiden estimate for Trident West while the company is also updating the overall resource for Trident project, which sits within the broader Plutonic Dome (Marymia) project.
Trident Main underground plan
Results as well as geotechnical data gained from additional holes will also be used for portal planning to access the Trident high-grade underground zone.
Trident West deposit is the up-plunge expression at surface of the high-grade Trident Main deposit.
The open pit resource definition drilling program comprised five reverse circulation (RC) drill-holes totalling 520 metres.
Other high-grade results were:
- 4 metres at 4.22 g/t from 87 metres, including 1-metre at 8.01 g/t;
- 2 metres at 2.87 g/t from 19 metres and 1-metre at 5.35 g/t from 73 metres; and
- 2 metres at 1.63 g/t from 62 metres.
Further results awaited
A further six RC holes for 1,192 metres were also completed to the east of the Trident West open-pit target to test the linking zone between the two deposits.
The Trident Main resource estimate will be finalised following release of these results, which is expected in the coming weeks.
This will also facilitate the completion of underground mine planning at Trident Main.
Geotechnical and metallurgical drilling
In addition to the resource definition drilling, the company completed a program of geotechnical and metallurgical drilling at Trident West.
Four technical drills and one metallurgical hole were completed, with metallurgical test work on Trident West initiated to determine leach recovery and crushing-grinding parameters for the plant study.
Vango aims to develop Trident into a significant standalone mining and processing operation with upside potential to continually build the high-grade gold resource base.
