Dundas Minerals Limited (ASX:DUN) has completed its extensive auger soil sampling program at the Dundas Project, testing new conductive aerial electro-magnetic (AEM) anomalies in the northeast area of the Project.
Dundas reported in October that it had enlisted Sensore Ltd (ASX: S3N) to conduct proprietary 2.5D model inversion technology for re-inverting and modelling the SkyTEM airborne electromagnetic (AEM) survey data in the northeastern part of the Dundas Project area.
The outcomes were promising, as they revealed two new conductors, prompting Dundas to initiate an initial soil sampling program to further investigate these nickel and copper anomalies.

The Company collected 167 soil samples across the AEM anomalies at a target depth of roughly 1.5 metres below surface.
The samples have now all been collected and submitted for multi-element assay, with results anticipated in early December this year. Should assays from the samples return elevated levels of targeted metals such as nickel and copper, Dundas expects it will conduct further exploration and drilling to follow.
The Company reports it has obtained a library of samples across the Dundas Project area, from exploration conducted 2021/22, a program across the Central exploration target in 2022, and more recently from the northwest soil sampling program that was completed in April this year.
These will be beneficial in forming a baseline to assist in the validation of any geochemical anomalies identified from the newly sampled areas.
The drilling completed at Central Target earlier in the year determined a combination of graphite and barren sulphides were responsible for the strong conductive AEM anomaly discovered.
As a surface geochemical anomaly was absent, Dundas believes the geochemical analysis of soil samples will be important in defining new conductive targets before consideration is given to drilling.
Turning to its other exploration endeavours, Dundas announced earlier this month that it was making significant advancements in its newly acquired Kalgoorlie gold projects, unveiling remarkable high-grade gold soil anomalies in Windanya while preparing for its upcoming drilling program.
Results from the Olympia prospect were promising, revealing a substantial 1.2-kilometre-long and 600-metre-wide gold anomaly. This anomaly was detected through three lines of auger sampling, each spaced 600 metres apart, featuring peak gold values of 128ppb and 113ppb.
The Windanya Project, located approximately 12 kilometres south of Baden-Powell, involved the analysis of 756 soil samples. Peak gold assay results from the samples included 696ppb, 530ppb, 493ppb, 483ppb, and 478ppb (ranging from 0.7gpt to 0.48gpt).
Following these findings, Dundas is in the process of formulating an initial drilling program for Windanya which will be submitted for the necessary approvals upon completion.
