Terra Metals Limited (ASX:TM1) has delivered a major breakthrough at its Dante Project, with the Terra Metals Ltd multi-metal discovery revealing multiple titanium-sulfide reefs containing an impressive suite of critical metals including copper, cobalt, nickel, and platinum group metals (PGMs) at the Southwest prospects. The discovery reveals thick, continuous reef packages that dwarf the company's existing resource base, with potential to fundamentally transform the project's scale and economics.
Major Discovery Delivers Thick, High-Grade Reefs
The first eight drill holes from the Southwest prospects SW3 and SW4 have uncovered exceptional results that highlight the significant potential of this newly defined exploration area. Most notably, SWRC008 delivered 59 metres at 0.95% copper equivalent (CuEq) with 172 ppm cobalt from 131 metres depth, including a higher-grade zone of 31 metres at 1.14% CuEq with 198 ppm cobalt.
Additional standout results from SWRC005 include 61 metres at 0.70% CuEq from surface, incorporating multiple high-grade zones including 5 metres at 1.09% CuEq at surface and 4 metres containing 1,228 ppm cobalt and 0.16% nickel. Furthermore, SWRC004 intersected 58 metres at 0.55% CuEq with 185 ppm cobalt, featuring a cobalt-rich zone of 4 metres at 981 ppm cobalt.
Managing Director Thomas Line commented:
"These early assay results mark an important milestone for Terra Metals, confirming a new titanium–sulfide reef system at the Southwest Prospect. The combination of thick, sulfide-rich reef packages and encouraging copper–nickel–cobalt and PGE values points to strong potential to expand the scale and diversity of mineralisation within the Dante system."
What makes these results particularly compelling is the reef thickness. The Southwest reefs are delivering intercepts up to 58 metres thick – approximately 11 times thicker than the ~5 metre basal reef within the current 148 million tonne Mineral Resource Estimate.

Understanding Layered Intrusions: The Bushveld Connection
The Terra Metals Ltd multi-metal discovery sits within the Jameson Layered Intrusion, part of the globally significant Giles Intrusive Complex. This geological setting is directly comparable to South Africa's Bushveld Complex, which contains an estimated 2.2 billion ounces of platinum group elements, making it one of the world's most important PGE sources.
Layered intrusions form when large volumes of magma cool slowly, creating distinct mineral-rich layers through gravitational settling and chemical differentiation. These processes concentrate valuable metals into specific horizons or "reefs" that can extend for many kilometres.
The Southwest discovery demonstrates classic features of this process, with increasing evidence of mafic-ultramafic geology, higher sulfide content, and locally high-grade cobalt and nickel sulfide mineralisation. For instance, the thick reef packages identified show the characteristic multi-metal signatures typical of world-class layered intrusion systems.
For investors, this geological setting is crucial because layered intrusions typically host multiple reef systems across extensive strike lengths. The fact that Terra Metals has identified thick, sulfide-rich reefs with strong multi-metal signatures suggests the potential for a world-class deposit system comparable to other major layered intrusion discoveries.
Strategic Timing: Cobalt Prices Surge Nearly 100%
The discovery comes at a particularly opportune time, with cobalt prices having risen by approximately 99.9% year-over-year to over US$48,570 per tonne. This dramatic price increase reflects growing demand for cobalt in battery technologies and limited global supply, making the Terra Metals Ltd multi-metal discovery increasingly valuable.
The Southwest reefs are delivering consistently elevated cobalt grades, with multiple intercepts exceeding 150-200 ppm cobalt, and peak grades reaching 1,228 ppm cobalt. However, this cobalt content, combined with copper, nickel, and PGM values, positions the Southwest discovery as a potential multi-commodity operation capable of benefiting from diverse commodity cycles.
Expansion Potential: 45 More Holes Pending
Perhaps most significantly for investors, these impressive results represent just the beginning of what could be a much larger discovery. Terra Metals has completed 49 drill holes to date across the Southwest prospects, with assays still pending for 45 additional holes.
Consequently, the current results represent less than 20% of the initial drilling programme. Furthermore, the company has recently mapped an additional 5.2 kilometres of new reef at Southwest that wasn't included in previous strike-length estimates.
In addition, ongoing downhole electromagnetic programmes targeting high-sulfide zones at prospects SW1, SW5, and SW6 suggest significant news flow ahead. The exploration pipeline indicates multiple catalysts that could further enhance the Terra Metals Ltd multi-metal discovery.
Upcoming Catalysts Timeline:
- Assay results from 45 pending drill holes
- Downhole EM results from six diamond drill holes
- Extended drilling programmes across multiple Southwest prospects
- Continued reef mapping and target generation
Investment Thesis: Scale Transformation Potential
Terra Metals' Southwest discovery represents a potential step-change in the company's asset base. The existing 148 million tonne Mineral Resource already establishes Dante as a significant multi-metal project, but the Southwest reefs suggest this could expand dramatically.
| Current Dante Resource vs Southwest Discovery Characteristics |
|---|
| Existing Resource: ~5m thick basal reef |
| Southwest Reefs: Up to 58m thick reef packages |
| Scale Factor: ~11x thicker reef packages |
| Strike Potential: Additional 5.2km of newly mapped reef |
The discovery's distinct mineralisation style, featuring massive to semi-massive copper-nickel-PGE-cobalt sulfide mineralisation, suggests Terra Metals may have discovered a different and potentially higher-grade reef system within the broader Dante complex. This geological diversity provides multiple development pathways and reduces single-commodity exposure.
With metallurgical testwork already demonstrating the potential for three separate concentrate streams (copper-gold-PGM sulfide, titanium ilmenite, and vanadium-magnetite), the Southwest discovery could significantly enhance project economics through increased scale and grade.
Why Investors Should Track Terra Metals
Terra Metals has positioned itself at the forefront of Australia's emerging multi-metal sector with the Dante Project offering exposure to critical metals essential for the energy transition. The Southwest discovery validates the company's systematic exploration approach and highlights the scale potential within the broader 80-kilometre strike length of prospective tenure.
Key differentiators include:
Geological Advantage: Direct comparison to the Bushveld Complex provides a proven geological model for world-class multi-metal deposits.
Commodity Diversification: Exposure to copper, titanium, vanadium, cobalt, nickel, and PGMs provides natural hedge against individual commodity cycles.
Early-Stage Discovery: With assays pending from 45 drill holes and extensive untested targets across the broader project, Terra Metals offers significant exploration upside.
Infrastructure Access: West Musgrave location provides access to existing infrastructure development initiatives in the region.
What Makes This Discovery Different?
The Terra Metals Ltd multi-metal discovery stands out due to its exceptional thickness and multi-commodity potential. Unlike traditional single-metal deposits, this system offers diversified exposure across multiple critical metals sectors.
Key Takeaway:
Terra Metals has discovered what appears to be a fundamentally different and potentially larger-scale reef system at Southwest, with 11 times the thickness of existing resources and strong multi-metal grades. With 45 drill holes pending results and extensive untested targets, the company offers compelling exposure to potential resource growth in one of Australia's most prospective geological settings.
The combination of exceptional drill results, favourable commodity pricing (particularly cobalt), and extensive exploration pipeline positions Terra Metals as a key stock to watch as the Southwest discovery continues to unfold through 2025.
