Dundas Minerals Ltd (ASX:DUN) has begun a 118 square kilometre detailed ground gravity geophysical survey at its Jumbuck prospect in the prospective Albany-Fraser Orogen in Western Australia
The survey follows the company’s discovery of broad zones of nickel mineralisation during recent drilling at Jumbuck, which provided notable assays from two holes of
- 34 metres at 0.23% nickel, including 6 metres at 0.38% nickel; and
- 33 metres at 0.14% nickel and 0.27% chromium.

Survey details
The nickel, copper and gold explorer will conduct its gravity survey over 118 square kilometres, within which there are well-correlated gravity, conductivity and magnetic anomalies.
This survey will be conducted at a line spacing interval of 500 metres and a reading station interval of 100 metres. A total of 2,482 stations are planned.
The work is expected to take approximately two weeks to complete, with the company aiming to provide improved target resolution compared to the previous wider-spaced survey completed in October 2021.
Exploration targeting is expected to more accurately define inferred mafic and ultramafic intrusions, similar to the adjacent Jumbuck prospect.
Dundas sees this as highly prospective for the occurrence of further nickel, with managing director Shane Volk saying, “yet again we have been extremely fortunate that our geophysical survey contractor Atlas Geophysics was working nearby and we have been able to quickly mobilise them to the Jumbuck area for this survey.
"We are very encouraged by the results from the Jumbuck drilling campaign and this survey will greatly assist with our planning for further exploration work in the area.”
