DY6 Metals
Overview
Rare earth elements (REEs) collectively represent some of the most critical minerals in the world. This group of interrelated minerals has an incredibly broad range of applications — everything from military equipment to consumer electronics. They are also pivotal in the global transition to clean energy and decarbonisation. Neodymium magnets, for instance — composed of neodymium, iron and boron (NdFeB) — are increasingly being used in wind turbines and electric vehicle motors. Dysprosium and Terbium are added to high performance NdFeB magnets to increase the magnet’s resistance to demagnetisation, thereby improving performance through higher operating temperatures.
REEs are also essential to the production of devices such as smartphones, lending context to the news that alongside other critical minerals such as lithium and cobalt, global demand for REEs is expected to increase by as much as 600 percent over the next several decades.
It is clear the world needs to ramp up rare earths production — a challenge DY6 Metals (ASX:DY6) understands. This mineral exploration company holds a 100 percent interest in six highly prospective critical metals projects in Malawi. As one of the most stable jurisdictions in Southern Africa, Malawi is home to considerable mineral wealth — a fact which, alongside its mining-friendly government, has seen the country enjoy significant mining investments over recent years.
Successful completion of maiden 35-hole RC and 8 DDH drilling program for 3,643m RC and 900m of DDH at Machinga HREE and Nb project was completed in September 2023. Assay results of the final diamond Drill hole program returned an average of 29 percent heavy rare earth oxide to total rare earth oxide (HREO:TREO) and 3.6 percent dysprosium (Dy) and terbium (Tb) (DyTb:TREO) at a cutoff grade of >0.25 percent TREO.
DY6 expanded its overall strategic footprint in Malawi to a total of 1,080 square kilometres by staking a carbonatite ring complex in southern Malawi known as Tundulu and several licences considered to be highly prospective for lithium. An exclusive prospecting licence application for 91.5 square kilometres was submitted over Tundulu while an additional four exclusive prospecting licence applications totaling 746.7 square kilometres have also been submitted for the company’s Mzimba (West, Central and South) and Karonga projects.

Key Projects
Machinga
Machinga project location
Located within the Chilwa Alkaline Province (the same province that hosts Lindian’s Kangankunde project), Machinga is DY6's flagship project. The original exploration licence, covering 42.9 square kilometers, was acquired in light of uranium channel radiometric anomalies located by a country-wide airborne survey in the 1980s. In 2023, the Malawian Department of Mines granted DY6 Metals an additional licence area for Machinga, which increased its total area to 197 square kilometres. The Machinga radiometric anomaly is continuous along a strike of approximately 7 km, indicating that potential to discover further eudialyte-hosted REE mineralisation may be significant.
Project Highlights:
- A significant HREE project
- 40km east of Lindian’s (ASX:LIN) “Kangankunde”
- Successful completion of maiden 35-hole RC and 8 DDH drilling program for 4,543m at Machinga HREE and Nb project
- Initial exploration focused on historical 2010 drill program for 4000m (Machinga North)
- Future exploration includes extending NE into new licence EL0705 and south along the anomalous zone
- 2023 Maiden Reverse Circulation and Diamond Core drill Assay significant results:
- 15.1 metres @ 1.01 percent TREO, 0.36 percent Nb2 O5 from 23.9 metres (3.71 percent Dy/ Tb/TREO) incl. 4 metres @ 1.75 percent TREO, 0.63 percent Nb2 O5 from 33 metres (3.8 percent Dy/Tb/TREO) drilled downdip (MDD007)
- 13 metres @ 0.65 percent TREO, 0.25 percent Nb2 O5 from surface; incl. 1 metres @ 1.06 percent TREO, 0.37 percent Nb2 O5 from 7 metres, and 1 metres @ 1.28 percent TREO, 0.42 percent Nb2 O5 from 9 metres (MR019)
- 7 metres @ 1.42 percent TREO with 0.49 percent Nb2 O5 from 65 metres (MR011) – 16 metres @ 0.54 percent TREO with 0.21 percent Nb2 O5 from 78 metres, incl. 3 metres @ 1.63 percent TREO, 0.7 percent Nb2 O5 from 87 metres (MR005)
- 11 metres @ 0.74 percent TREO, 0.29 percent Nb2O5 from surface (3.8 percent DyTb/TREO) incl. 2 metres @ 1.36 percent TREO, 0.49 percent Nb2O5 from 6 metres (4 percent Dy/Tb/TREO) (MR024)
Mineralisation
- Strongly mineralised hydrothermal breccia system striking NW-SE and dipping shallowly ~35° to the NE has been confirmed by the recent drilling
- Drill cross sections demonstrate excellent continuity with radiometric contour predicting the mineralised higher-grade zone
- High grade HREE-Nb confirmed from RC and DD drill results at Machinga Central Zone
- The mineralisation at the Machinga alkaline complex contains a higher proportion of valuable dysprosium-terbium (DyTb) with results indicating an average 3.6 percent DyTb:TREO in samples greater than 0.25% TREO.
Salambidwe Project
Straddling the Malawi-Mozambique border, the Salambidwe project covers an area of 24.9 square kilometres, associated with the Salambidwe Ring Complex, which is known for hosting multiple notable carbonate deposits. Geology in the area is also associated with high radiometric values, typically associated with REE mineralization.
Project Highlights:
- Considerable Potential: The Salambidwe project is a virgin rare earth carbonate prospect. While no drilling has taken place at the project, rock-chip samples returned 2.05 percent TREO including 214 ppm dysprosium oxide.
- Area Geology: With a diameter of approximately 6 kilometres, the Salambidwe Ring Complex is largely syenite and nepheline syenite with an agglomerate rock core. Based on this geology and the radiometric signal, the project has the potential for REE mineralisation.
2023 Exploration Program
- DY6 has completed the initial geochemical and geophysical exploration programs at Salambidwe.
- Analytical results have been received for the grid-based soil and rock chip sampling. Results from the 128 soil and 386 rock chips expand the known area of anomalous responses.
- The maximum values from separate rock chip samples were 1.21 percent TREO & 0.12 percent Nb2O5; maximum values from separate soil samples were 0.23 percent TREO & 0.09% Nb2O5.
- The 45-line kilometre airborne geophysical program confirmed the highly concentric nature of the intrusive complex.
- DY6 is assessing the combined geochemical and geophysical data to refine targets prior to a maiden drill program.
Karonga Lithium Project
In 2024, DY6 Metals entered into an exclusive option to acquire an 80 percent interest in the Karonga lithium project, with granted licence EPL0659, spanning 39 square kilometres in northern Malawi. DY6 Metals Ltd submitted four (4) exclusive prospecting licence applications totalling 746.7 km2 in northern Malawi for tenements it considers to be highly prospective for lithium. The Mzimba licences cover a large area (710.5km2) and remain significantly underexplored for LCT pegmatites.
Reconnaissance field work at the Karonga identified some pegmatites of up to 500 metres in length with the potential to host lithium mineralisation. Rock chip samples include visually observed spodumene and lithium micas (lepidolite). Initial reconnaissance indicates huge potential for a major Li discovery and initial ground reconnaissance sampling at Mzimba South licence returned grades of 6.2 percent Li2O (lepidolite mica) and 0.3 percent Li2O (pegmatite rock assemblage), and also high in cesium and rubidium with significant potential for LCT pegmatite hosted mineralisation. The first pass program at Mzimba South consisted of 8 samples from 5 outcrop locations, where artisanal workers have been excavating pegmatites for gemstones (tourmaline, aquamarine and beryl).
Tundulu REE Project
‘Tundulu’ is a known carbonatite ring complex with abundant REE mineralisation, predominantly in the form of bastnaesite and apatite. Shallow historical drilling (1988) (>max depth of 50 metres), includes:
- 41 metres @ 3.7 percent TREO, from 8 metres (JMT-22)
- 17 metres @ 1.3 percent TREO, from surface and 14 metres @ 1.1 percent TREO, from 21 metres (JMT-14)
- 11 metres @ 2.2 percent TREO, from 17 metres and 14 metres @ 4.1 percent TREO, from 36 metres (JMT-17)
- 14 metres @ 1.1 percent TREO, from 3 metres (JMT-07)
Samples from a recent reconnaissance field visit at Tundulu have been despatched for laboratory analysis. Tundulu complements the company’s existing REE and critical metals portfolio in Malawi. A geological team recently undertook a reconnaissance field visit over parts of the licence application area and samples have been submitted for laboratory analysis in South Africa.
Ngala Hill
Situated just east of the Thyolo Fault, the Ngala Hill Project's zone of mineralization contains a strong magnetic anomaly indicative of an oxidized intrusive. Like Salambidwe, Ngala Hill is a relatively fresh asset. It has not been the target of any significant modern exploration efforts, though the results from historical works are nevertheless promising.
Project Highlights:
- Multiple Mineralization Zones: Ngala Hill's deposit takes the form of an ultramafic chonolith that intrudes onto an underlying Proterozoic Basement Complex quartz feldspar-amphibole gneisses. The chonolith is also cut by Karoo-age dolerite dykes. Currently, DY6 has identified three zones of palladium-rich palladium-platinum-gold-copper mineralization worthy of follow-up.
- Promising Historic Results: After trenching the deposit in 2000, Phelps Dodge identified the following mineralization:
- 12 metres at 3 grams per ton (g/t) platinum group elements (PGE)+gold
- 70 metres at 1.12 g/t PGE+gold, including 8 meters at 3.3 g/t PGE+gold
- Presence of Massive Sulphides: Historical exploration has identified massive sulphides with grades of up to 4 g/t palladium+platinum+gold and 0.7 percent copper in saprolite/saprock.
- Close Proximity to Major Infrastructure: Ngala Hill is located close to the Nacala rail/port corridor, with easy access to grid power.

Exploration Progress at Salambidwe
HIGHLIGHTS
- DY6 has completed the initial geochemical and geophysical exploration programs at the Salambidwe REE and Nb project.
- Assay results have been received for the grid-based soil and rock chip sampling. Results from the 128 soil and 386 rock chips expand the known area of anomalous responses.
- Maximum values from separate rock chip samples were 1.21% TREO & 0.12% Nb2O5
- The 45-line kilometre airborne geophysical program confirmed the highly concentric nature of the intrusive complex.
- DY6 is assessing the combined geochemical and geophysical data to refine targets prior to a maiden drill program.
Ground based grid controlled geochemical sampling (Figure 1) was undertaken to confirm historical exploration results of Globe Metals and Mining (“Globe”) and to expand the footprint of anomalous responses. Previous activity had not closed off the anomalous zones, nor had airborne geophysical surveys covered the area due to its proximity to the border with Mozambique.
Globe completed a sampling and ground radiometric survey over part of the central ring complex area of the intrusion outlining several zones of strongly anomalous TREO and Nb responses, numerous zones extended to the limits of the sampling. DY6’s sampling was specifically aimed at either extending or closing off these anomalous zones to the northern and western part of the licence.
The area of the historical sampling was not resampled, but several traverses were made across the outlined anomalous areas to ensure consistency and coherency of results (Figure 2). Absolute values obtained from the DY6 exploration appear to be slightly lower in tenor than the historical data; it is interpreted that this is due to the majority of the DY6 sampling being peripheral to the historical sampling and extending away from the central anomalous area.
DY6 detailed sampling expanded the anomalous areas on 100m x 100m spacing and the more regional and confirmatory sampling was at 100m intervals along lines 500m apart.
Figure 1: Geochemical sampling at Salambidwe prospect
Figure 2: DY6 Anomalous TREO Responses on RTP1VD aeromagnetic data at Salambidwe
The airborne data shown in Figure 2 shows the strong circular and concentric character of the intrusive syenite units at Salambidwe; note the area of anomalism seems to show a more subdued magnetic character, presumably due to alteration. Strong radiometric responses coincide with this area as shown below in Figure 3.
Figure 3 shows the extent of the historical TREO anomalism overlaid on the Total Count (TC) radiometrics image and the anomalous extensions generated by DY6’s exploration sampling.
Though a portion of the western anomalous zone is outside the current tenure; being too close to the Mozambique/Malawi border; this anomalous trend is now >2km long. The anomalous zone to the west of the western zone which does not overlay strong radiometric response requires further exploration. Both soils and rock chips return anomalous responses in this zone.
The eastern zone is approximately 1,700m long and nearly 1,000m wide near its northern limits.
