Reconnaissance Sampling Program Commences at Ngala Hill PGE Project to Follow up Historical Targets
HIGHLIGHTS
- Targeted reconnaissance sampling program commences at DY6’s highly prospective PGE, Cu & Ni project at Ngalla Hill, Southern Malawi
- At Ngala Hill, 3 key target zones of palladium rich Pd+Pt+Au+Cu mineralisation have been identified from historical trenching and limited drill testing
- DY6 will undertake a rock chip and soil sampling program to follow up on known high grade areas as well as aiming to expand the zone of mineralisation
- No significant modern exploration including electromagnetics (EM) to target massive sulphides has been undertaken at Ngala Hill
- Trenching by Placer Dome in 2000 included results of:
- 12m at 3g/t PGE+Au; and
- 70m at 1.12g/t PGE+Au, including 8m at 3.3g/t PGE+Au
- The main mineralised zone has only had limited modern drilling
The Company’s CEO, Mr Lloyd Kaiser said: “Our team in Malawi has actively built strong relationships with local communities across our projects and this early engagement at Ngala Hill is setting the foundation between the Company and the community as we prepare to mobilise the geo team and embark on our first exploration campaign at Ngala.”

Background on the Project
The Ngala Hill ultramafic chonolith is an arcuate-shaped intrusion, with dimensions of approximately 2.4km by 0.7km and was intruded into the underlying Proterozoic Basement Complex gneisses. The Ngala Hill Project is characterised by an intrusive ultramafic suite of pyroxenites and hornblende- pyroxenites that intrude basement gneisses. The pyroxenite facies of the ultramafic complex is prospective for platinum group elements (PGEs), predominantly palladium, and associated copper.
Initial work at Ngala Hill in the late 1960s included geochemical sampling programs undertaken by the British and Malawian Geological Surveys. Phelps Dodge started an exploration program for PGEs on Ngala Hill in 1999 with approximately 600 m of trenching. Metapyroxenite and amphibolite with an PGE- gold-copper nickel association was intersected trenching and yielded 1.41g/t Pt+Pd+Au and 1,430 ppm Cu over a length of 64m.
In 2000, Placer Dome confirmed further anomalies with encouraging results received from several trenches including 12m at 3g/t PGE+Au and 70 m at 1.12g/t PGE+Au, including 8m at 3.3g/t PGE+Au.

Heavy Rare Earths & Niobium Explorer DY6 Metals Lists On ASX Following Successful $7M IPO
- $7 million successfully raised via IPO, including $2.5 million from Hong Kong- based cornerstone investors, Zhenshi Group and Zhung Nam New Material Company
- Funds to be used for exploration on three 100%-owned rare earths and critical metals projects in southern Malawi
- Malawi is an attractive and stable mining jurisdiction with proven potential for hosting major rare earth deposits including Lindian Resources’ world class Kangankunde discovery (40km east of the Company’s Machinga Project)
- RC drilling is already underway at the flagship Machinga project, with diamond drilling scheduled to commence next month
- Drilling aims to follow up high grade 2010 results by Globe Metals and Mining (ASX:GBE)§Machinga is enriched in heavy rare earths (Dysprosium and Terbium) and Niobium
DY6’s listing follows a successful initial public offering (IPO), which raised $7 million. As part of this, the Company attracted a combined $2.5 million from Hong Kong-based strategic investors, Zhensi Group (HK) Heshi Composite Materials Co., Limited and Zhung Nam New Material Company Limited.
The funds raised in the IPO will be used primarily for exploration at the Company’s three 100%-owned rare earths and critical metals projects located in southern Malawi, a stable and attractive African jurisdiction with proven potential for hosting major mineral deposits.
DY6 has recently commenced a 5,000m program of reverse circulation and diamond drilling at the flagship Machinga project, only 40km east of Lindian Resources’ Kangankunde carbonatite discovery, which is widely regarded as the world’s best undeveloped rare earths project.
Machinga is particularly enriched with high-value heavy rare earth elements dysprosium and terbium. The project also holds significant niobium and tantalum potential as well.
Non-executive Chairman Dan Smith said: “DY6 has recently started its maiden drill program at the exciting Machinga project. In addition to being a potential source of the critical heavy rare earth elements Dysprosium and Terbium, Machinga also contains significant Niobium mineralisation.
The Company is seeking to emulate the success of Lindian Resources in proving up a major critical minerals project in southern Malawi. We believe the projects and the team we have assembled provide us with an excellent opportunity.”

Six targets have been identified to date within the Machinga North concession and the Company will be following up on previous high grade intercepts from a previous 2010 campaign undertaken by Globe Metals and Mining (ASX:GBE).
DY6’s other projects in southern Malawi, Salambidwe and Ngala Hill, have also been subject to previous exploration: rock chips from Salambidwe returned high grade values of TREO and Nb while soil samples from Ngala Hill and limited previous drilling by Phelps Dodge returned high grade results of Pd, Pt, Au and Cu.
The Company plans to carry out detailed geophysical and geological sampling programs at Salambidwe to aid in defining targets for a maiden drilling campaign towards the end of the year. RC drilling at Ngala Hill is scheduled for around the same time.

Table 2 - 2024 Drill Hole Assay results summary to date 2024 diamond drill hole program in the Fjord Area. Assay results are reported for drill holes D, E and F. A1, A2, B and C were reported on 22 August 2025. Remaining assay results for holes G to Z are expected to be reported in Q3, 2025.
Background – Fjord Deposit Drilling
The 2024–2025 drilling campaign in the Fjord area has targeted confirmatory and step-out holes to:
- Validate historical drilling data.
- Refine the geological model for resource estimation.
- Provide material for metallurgical and environmental test work.
All drill holes in this program are vertical, intersecting the sub-horizontal layers at true thickness. The three holes reported here return TREO grades between ~0.40% and 0.42% with approximately 26% HREO, along with ZrO₂ values of 1.57–1.58% and gallium oxide contents of 93–99 ppm. These results are consistent with historical assays and demonstrate the persistence of grade and mineralogy across the Fjord deposit.
From a deposit classification perspective, the kakortokite-hosted REE mineralisation is best described as stratiform magmatic, confined entirely to the kakortokite unit and not observed in adjacent lithologies such as lujavrite or naujaite. This strong lithological control underpins confidence in resource modelling, supports bulk mining strategies, and provides reliable input for geology domaining.
Given the continuity of mineralization over several kilometres, the Fjord deposit represents a significant portion of the overall Tanbreez mineral inventory. Ongoing drilling is expected to further delineate these resources, with pending assays from additional holes likely to extend the known mineralised envelope and refine the grade distribution.
Sampling over the 2024 diamond holes was taken over kakortokite intervals above the Black Madonna lower boundary.
- Collar data: All collar locations, RLs, azimuths, dips, and hole lengths have been clearly presented in Table 2 of the report.
- Assay data: Table 1 in the report provides the suite of weighted average downhole assay results for TREO, HREO, Ga₂O₃, and other oxides.
- True widths: All drill holes are vertical (-90°) through sub horizontal mineralised layers, so intersections are true widths.
- No cut-off grades or metal equivalents were applied. All assays are reported at face value.
Gallium Results
The gallium oxide Ga2O3 mineralization assay results ranges from low to high is 90ppm to 100ppm for the four 2024 drillholes published to date.
Drill holes that were not assayed for gallium, tantalum and niobium in 2013 will be assayed from existing pulps submitted to ALS Metallurgical in Perth for analysis in the coming months.
ALS laboratories will also assay all sample for gallium for the 2024 and 2025 drill holes with results that will be published in September and October 2025. The gallium oxide results for all diamond holes published to date may add a credit to the TREO-HREO mixed concentrate.
