Dundas is actively exploring for gold at the Windanya and Baden- Powell gold projects, located adjacent to the Goldfields Highway ~60km north of Kalgoorlie, Western Australia, and ~15km north of the Paddington gold mill.
Assay results from 1 metre sample intervals – Rockland
On 12 December 2024, Dundas Minerals announced the discovery of a new 1 km zone of gold mineralisation from its maiden RC drilling program at Rockland, based on assay results from 4 metre composite samples. Subsequently, individual 1 metre samples relating to the mineralised portions of drill holes were submitted for assay.
Results from these assays highlighted multiple intercepts of high grade gold mineralisation at Rockland, with several gold grades significantly higher than the initial composite samples.
Of the 1 metre samples that were submitted, twenty returned gold assays of greater than 2g/t (Table 1), and 67 samples returned gold assays of between 0.5g/t and 2g/t. Significant gold assay results (above 1 gram per tonne) are provided in Appendix 1.
Importantly, these latest assay results confirms the approximate 1km long trend of significant gold mineralisation at Rockland, and indicates a new gold mineralised zone located between the historic Milford and Windanya North prospects. The mineralisation spans the entire length of the granted Mining Lease, and potentially extends north to the Aquarius gold deposit.
Mineralisation comprises an oxide supergene zone in the deeply weathered mafic host lithologies, above a series of stacked structures interpreted to dip shallowly to moderately to the east in the transitional to fresh rock. As illustrated in Figure 1, gold mineralisation is interpreted as trending north – south, which is consistent with the regional trend.
Detailed three dimensional modelling of these latest results is in progress to assess the orientation of mineralisation in fresh rock (below the oxide zone) and will provide the foundation to plan follow-up drilling.
Commenting on the one metre gold assays from the Rockland drilling, Dundas managing director Shane Volk said:
‘’As indicated by the assay results from the initial 4-metre composite samples, results from these 1- metre samples confirm the presence of wide-spread gold mineralisation within the granted Rockland Mining Lease. In many instances the mineralisation is at relatively shallow depth (100 metres or less), with some very nice high grade results returned in several holes – up to 14.9 grams per tonne.’’
‘’Three dimensional modelling of these latest results is in progress. The latest drilling results, combined with available historical drill data within the lease will enable us to make an updated interpretation of the mineralisation trend and develop an exploration model to assist with the planning of further exploration both within the highly prospective M 24/974 and the broader Windanya Gold Project area.’’

Background: Rockland Mining Lease
On 8 October 2024, Dundas Minerals announced that it had executed an exclusive 12-month option to acquire 100% of granted mining lease (ML) M24/974 (Rockland).
Rockland is strategically situated between the Aquarius and Scorpio gold prosects (Figure 1), where on 6 February 2024, Dundas announced high grade gold intercepts from an initial drilling program, including: Aquarius (3m @ 10.2 g/t from 109m; 2m @ 6.5g/t from 70m); and Scorpio (2m@ 3.2 g/t from 9m; 1m @ 6.5g/t from 49m).
The area comprising the Rockland ML has been subject to historic shallow drilling during the 1980s, which was mostly to a maximum depth of 50m (RAB). Also, a series of RAB holes to a maximum depth of ~90m was drilled in the early 2000s, plus 12 RC holes at the Windanya North prospect. More recently the current tenement owner drilled 3 RC holes at depths between 140m and 173m, also at Windanya North. However, the drilling recently completed by Dundas Minerals is the first to systematically test for gold mineralisation at Rockland to depths beyond 50m.

EMU NL
Investor Insight
EMU NL is an Australia-focused base and precious metals exploration company offering a compelling opportunity in the highly lucrative copper space. A strategic focus on delineating a large-scale copper porphyry system at its Yataga Copper Project at Georgetown in Northern Queensland, combined with a leadership team of significant global experience and expertise, and an upward trending copper market, all make EMU NL worthy of considerable consideration for any investors looking at the copper sector.
Overview
EMU NL (ASX:EMU) is an ASX-listed precious and base metals exploration company with two active projects in, Australia: Yataga Copper Project in Georgetown (Queensland) and the Badja gold, tungsten and lithium project (Western Australia). EMU’s primary focus is accelerating exploration at the highly promising Yataga Copper Project.
Australia is one of the most attractive regions for mining, according to the Fraser Institute. It ranks Queensland as the 13th most attractive destination for mining investment.
In 2023, Queensland's mines yielded 12.6 tons of gold, positioning it as Australia's fourth most prolific state for this precious metal. The company's presence in relatively attractive mining jurisdictions positions it to capitalize on opportunities in Australia's resource sector and deliver sustainable returns to its shareholders. The recent fundraises of AU$1.45 million have provided sufficient funding to advance its exploration projects and EMU is planning its maiden drilling programme at the Yataga Copper Project in 2025.
Gold and copper continue to demonstrate bullish trends. Various factors are driving the surge in copper prices, including demand patterns such as upgrades in utility grids, the increasing use of copper in electric vehicles, and housing construction. Additionally, the growing energy demand from data centres powering AI applications and servers contributes to the increased need for copper. Both gold and copper prices have hit their all-time high in 2024, enhancing the prospects for junior miners to progress their projects and potentially secure financing easily.
Key Projects
Georgetown Project
The Georgetown project tenements span 850 sq. km. in North Queensland and comprise three exploration permits: Georgetown, Perpendicular Peak and Fiery Creek. Of these, Fiery Creek is the most promising and the current exploration interest for EMU as it covers the Yataga Copper Project.
The Georgetown tenements are located in a resource-rich yet under-explored region in Queensland’s far north, situated within the Georgetown mining district, with a significant history of mining activities and mineral discoveries.
EMU has identified the Yataga Copper Project as a massive-scale copper porphyry system within the 70 sq. km. Yataga Igneous complex. During 2023 and 2024, EMU's reconnaissance efforts at Fiery Creek yielded substantial geochemistry success with more than 8 sq km of highly anomalous copper results from the sampling of terminte mounds by pXRF. EMU concluded 2024 with two geophysics surveys with results currently pending. EMU has advised that it will drill targets during 2025 following completion of the wet season.
The 2023/24 work has confirmed significant, large-scale potential of the project.
The fieldwork has provided support for a large-scale copper porphyry system at the Yataga Copper Project. Drilling results this year will confirm the potential however EMU is targeting large economic bulk tonnage copper resources from shallow ore bodies at Fiery Creek and the Yataga Valley prospects.
Badja Project
The Badja project is located 32 kilometres southeast of the township of Yalgoo and covers an area of 870 hectares. The project's tenements include 2 centrally granted mining leases an adjoining mining lease application covering 279.3 hectares, and a granted exploration license covering 590.3 hectares. EMU’s previous drilling work has identified areas that are prospective for high-grade gold, tungsten and lithium.
EMU is evaluating options to maximize the value of the project, either through sale or retention.
Yataga Copper Project
The Yataga copper project is composed of two prospects overlaying the copper geochemistry anomalous zones within the Yataga Igneous Complex. Most recent discoveries include widespread surficial copper mineralisation along the NNW-SSE shear zone in the central part of the Yataga Copper Project. Surface geochemical surveys have updated EMU’s ecological modelling and identified multiple intra-pluton porphyry copper centres close to the surface. The company’s
recent work has identified a combined area of 8 sq. km of copper-in-soil anomalism with significant potential for expansion. The results from EMU’s field work continue to prove the project’s potential to be a global tier 1 scale copper discovery.
