Blaze Minerals has identified a significant copper-in-soil anomaly spanning 1000m by 100m at its Dinokwe Base Metals Project, highlighting a new mineralisation style associated with a major fault zone within the Limpopo Mobile Belt.
- Copper-in-soil anomaly up to 288ppm over 1000m x 100m
- Anomaly aligns with a prominent fault zone indicating new mineralisation style
- Soil sampling campaign ongoing with plans for trenching and infill sampling
- Dinokwe Project covers ~1771km2 in Botswana’s Limpopo Mobile Belt
- Project acquisition pending completion of 90% stake in B&J Geoconsultants
Significant Copper Anomaly Emerges Early in Exploration
Blaze Minerals Limited (ASX:BLZ) has revealed a copper-in-soil anomaly stretching roughly 1000 metres in strike and 100 metres wide at its Dinokwe Base Metals Project in Botswana. The anomaly, with copper values peaking at 288ppm, was detected within the first weeks of an extensive soil sampling campaign, underscoring the prospectivity of the region. This discovery is particularly notable as it coincides with a prominent fault zone exhibiting signs of significant fluid flow, suggesting a new style of mineralisation beyond the typical ultramafic and amphibolite-hosted systems previously targeted.
Geological Setting and Exploration Strategy
The Dinokwe Project, covering approximately 1771 square kilometres, lies within the Limpopo Mobile Belt (LMB), a geological province known for hosting substantial base metal deposits. Notably, the nearby Selebi-Phikwe copper-nickel deposit, about 150 kilometres north, boasts an inferred resource of 24.7 million tonnes at 1.50% copper and 0.92% nickel. Blaze is targeting magmatic and hydrothermal copper-nickel mineralisation within the Mahalapye and Baines Drift Complexes that underlie the licenses. The company’s approach involves systematic soil sampling along traverses spaced between 100 to 400 metres, with samples taken at 50-metre intervals, aiming to delineate anomalous zones for follow-up trenching and potentially drilling.
Technical Details and Validation Efforts
The soil samples were collected from the B-horizon, approximately 30 to 60 centimetres below surface, then dried, screened to minus 1 millimetre, and analysed using a handheld Olympus Vanta M Series XRF device. While the results are qualitative and intended to highlight anomalous copper concentrations, several duplicate samples have been submitted to an external laboratory in Cape Town for validation, with results pending. The sampling campaign is designed to refine target areas, with infill soil sampling and trenching planned to better define the host structures and mineralisation extent.
Project Ownership and Regional Exploration Context
Blaze has a binding agreement to acquire up to 90% of B&J Geoconsultants, which holds the Dinokwe licenses. This acquisition, announced in March 2026, significantly expands Blaze’s footprint in Botswana, complementing its other projects in the Kalahari Copper Belt and Molopo Farms Complex. The Limpopo Mobile Belt’s exploration pedigree is bolstered by past work from companies like Albidon Limited, which intersected notable sulphide mineralisation in the Baines Drift Complex. Blaze’s discovery of a copper anomaly along a major shear or fault zone opens a fresh avenue for exploration that could differentiate its projects from historical targets, as the company leverages regional geophysics and geological mapping to identify similar structures across its tenure.
Next Steps and Market Implications
Following the completion of the current soil sampling campaign, Blaze plans to undertake trenching over the copper anomaly to gain better geological and structural context. The company also intends to expand exploration to other priority zones defined by coincident fault or shear zones, potentially uncovering further anomalies. This measured approach aligns with Blaze’s strategy to advance high-margin, high-grade deposits in underexplored but highly prospective regions. The Dinokwe discovery adds momentum to Blaze’s Botswana portfolio, building on its recent 90% stake in copper projects and complements its critical minerals focus seen in Uganda’s Ntungamo Project where the company recently reported new mineral discoveries. Investors will be watching how these early-stage results translate into more definitive drilling targets and resource delineation in the coming months.
Bottom Line?
Blaze Minerals’ early-stage copper anomaly at Dinokwe introduces a compelling new mineralisation style in a proven belt, but validation and follow-up work will be critical to confirm its potential.
Questions in the middle?
- Will laboratory assay results confirm the handheld XRF copper values and anomaly extent?
- How will trenching and infill sampling refine the structural controls on mineralisation?
- What impact will the completion of the B&J acquisition have on project development timelines?
