Midas extends high-grade copper-silver mineralisation at Spaatzu Prospect
Midas Minerals has extended high-grade copper-silver mineralisation at its Spaatzu Prospect in Otavi Mountain Land, with a new drillhole intersecting a 52-metre mineralised zone, including a 32-metre interval averaging 1.8% copper and 11 g/t silver.
The latest result comes from hole SPRC062, drilled about 300 metres west of the original discovery hole, and is being interpreted as a key step in defining the orientation of higher-grade zones within the prospect.
Within the broader interval, the company reported a higher-grade section of 12 metres at 2.6% copper and 15 g/t silver from 152 metres, based on portable XRF readings.
The new intercept builds on previously reported shallow high-grade results across the prospect, including 13 metres at 1.77% copper and 39.5 g/t silver, with a higher-grade core of 5 metres at 3.42% copper and 81 g/t silver, and 21 metres at 1.18% copper and 37.9 g/t silver, including 8 metres at 2.01% copper and 66 g/t silver.
To date, Midas has completed 77 reverse circulation holes for 8,772 metres, testing about one kilometre of strike at Spaatzu.
The results are helping the company refine its understanding of the geological controls on mineralisation, which appears to combine both structurally controlled high-grade zones and broader stratabound mineralisation.
Managing director Mark Calderwood said the latest drilling was beginning to define the geometry of the system, noting that mineralisation is widespread and includes both higher-grade structurally controlled zones and broader disseminated styles.
He said the new hole was particularly important in helping vector the down-plunge orientation of the high-grade zone first identified in earlier drilling.
Geologically, Spaatzu is emerging as a complex system located on the northern flank of the Merwe dome, defined by a 2.5-kilometre copper soil anomaly.
Mineralisation is associated with faulting, folding, and brecciation and is hosted in both the Ombombo Subgroup and the overlying Chuos diamictite.
The Ombombo unit is considered the primary host and is comparable to the Lower Roan Formation of the Zambian Copperbelt, one of the world’s most prolific copper provinces.
The system shows clear zonation, with copper, silver, lead, manganese and barite linked to hydrothermal processes.
Higher-grade copper-silver mineralisation appears to be concentrated along WNW-trending structural zones, while broader stratabound mineralisation occurs as more disseminated copper-lead with minor zinc.
Importantly, Spaatzu is not being explored in isolation. The prospect lies about 12 kilometres west of the high-grade T-13 copper-silver deposit, where Midas is currently running two diamond drilling rigs focused on resource definition.
At the same time, two RC rigs remain active at Spaatzu, with further assay results expected as the campaign progresses.
The company is also awaiting laboratory assay results for an additional 34 holes drilled in 2026, which are expected to provide a more complete picture of the system’s scale and grade distribution.
While portable XRF readings provide an early indication of mineralisation, the company cautioned that these results are preliminary and must be confirmed by laboratory analysis.
Previous work at Spaatzu has shown a strong correlation between XRF readings and final assays.
With drilling continuing and multiple rigs active across the Otavi project, Midas is now moving beyond discovery toward defining the extent and continuity of mineralisation.
The combination of wide intercepts, consistent grades and structural controls is beginning to position Spaatzu as a potentially significant copper-silver system within one of Namibia’s most prospective but underexplored mineral belts.
