Dundas Minerals commences airborne survey over nickel-gold project
Dundas Minerals has identified anomalies across the new ground that is contiguous to its existing tenements.
Junior explorer Dundas Minerals (ASX: DUN) has kicked-off a closed-spaced, high-resolution airborne magnetic-radiometric survey at its namesake nickel-gold project in Western Australia’s Albany-Fraser Oregon.
The survey is being undertaken by Perth-based Magspec Airborne Surveys and will incorporate the high-priority Matilda South and North-East nickel-copper prospects.
Magspec will use a fixed wing aircraft on 100m-spaced lines across three blocks within the project area which currently have only wide-spaced magnetic and radiometric data available.
The central portion of the project is not being surveyed as 100m-spaced data is available in the public domain and has already been obtained by Dundas at no cost.
The public domain data (up to 500m-spaced lines) across the areas to be covered by the survey does not provide sufficient resolution for the advanced exploration targeting work being undertaken.
Dundas said the 100m line spaced data would provide the necessary detail for this work.
The survey is expected to take one week to complete.
Drilling completion
Meanwhile, Dundas has reported the completion of an inaugural reverse circulation drilling program at the Kokoda (gold) and Jumbuck (nickel) prospects.
Drilling commenced in December with an initial 15 holes planned at each prospect to 150m depth.
At Jumbuck, Dundas was following up on a rotary air blast hole from 2011 which was drilled to 22m depth and returned anomalous nickel grading 5,490 parts per million (or 0.55%) from a 2m bottom-of-hole composite sample.
A broad zone of anomalous sulphur was reported in the surrounding holes.
Dundas has also re-processed historic aerial electro-magnetic survey data partially covering the Jumbuck prospect and identified a late-time conductive anomaly which remained untested by drilling.
Previous exploration at Kokoda identified a 4km-long gold-copper trend which warranted further investigation via drilling at depth.
Shallow aircore drilling of one hole in 2012 was completed to a maximum 48m depth, with an average drilling depth of 20m for all other holes.
Some assays from both prospects are expected towards month end, while the majority will be ready in March.
