The Kranzberg Fault Zone, a twenty-kilometre strike length of gold-fertile structures that cross EPLs 6162 and 7261 and wrap around the Etiro Dome under EPL 6550, has become the centrepiece of Antler Gold’s exploration strategy in central Namibia.
Antler Gold says this zone, newly recognised after company geophysicists reprocessed government aeromagnetic data, represents a structural system that had not been adequately defined before due to magnetic attenuation over the 1,000-metre-high Erongo volcanic complex.
According to the company, downward continuation and reprocessing of the regional dataset revealed a network of thrusts, splays and jogs—features consistent with the deep-rooted structures that control orogenic gold systems elsewhere in the Damara Mobile Belt.
This zone, Antler notes, mirrors the geometry of the better-known Karibib Fault Zone, which hosts Osino Resources’ Twin Hills deposit.
Both systems trend ENE and NNE, developed during the late-Damaran D3–D4 transpressional event, and lie along the margins of domal culminations within Kuiseb Formation metasediments.
Antler emphasises that this structural setting is identical to the controls that localise mineralisation at Navachab and Twin Hills, two of Namibia’s most crucial orogenic gold discoveries.
In its technical commentary, the company stresses that D3–D4 structures served as conduits for hydrothermal fluids and are therefore the most prospective fluid pathways for gold deposition in the central Damara Belt.
Antler Gold’s position over the Kranzberg system is the product of a multi-year consolidation strategy.
The company says it first entered Namibia in late 2018 when it signed an option agreement with private Namibian vendors over EPL 6550 (Etiro Dome), involving staged cash payments totalling roughly C$200,000 and exploration expenditure commitments spread across two years.
This became Antler’s first foothold in the Damara Belt. In 2020, Antler expanded by acquiring EPL 6162 from a separate Namibian rights holder for a combination of modest upfront cash, deferred payments, and a firm work-program commitment that tied the economic value of the agreement to technical progress rather than ample cash outlays.
During 2021, the company added EPL 7261 under similar terms—low cash, high exploration spend—with Antler noting that the licence was strategically important because it captured the northern extension of the Kranzberg structures.
In parallel, Antler secured an option over EPL 6408, now central to the C2 targets, from local title holders for staged consideration totalling under C$100,000 and committed geophysical and sampling work.
Later acquisitions, including EPL 7960, EPL 8010 and EPL 7854, were tied to Antler’s 2023 definitive agreement with Fortress Asset Management LLC, a transaction the company describes as transformational.
The Fortress deal gave Antler access to six Exclusive Prospecting Licences totalling 25,766 hectares in exchange for modest staged payments, share issuances and exploration commitments rather than enormous acquisition costs, allowing Antler to consolidate an entire gold-fertile belt with limited dilution.
According to Antler, the intention behind the Fortress partnership was to apply systematic exploration—geophysics, geochemistry, mapping, and drilling—to a structural corridor analogous to those at Navachab and Twin Hills.
With these acquisitions complete, Antler became the dominant exploration company along the Kranzberg structural corridor, amassing more than twenty kilometres of strike across multiple domes and anticlines.
The company says this land position now covers the full length of the newly defined Kranzberg Fault Zone, giving it a first-mover advantage over a structural system not previously recognised in exploration models.
The historic footprint of the Kranzberg trend is noteworthy.
Within Antler’s licences lie several 1950s–1960s small-scale mines—Brown Mountain, Onguati and Western Workings—where rock-chip assays reached up to 80 g/t gold.
The company also reports gold-in-soil anomalies as high as 7,000 ppb, dramatically above background levels of less than 5 ppb.
Antler emphasises that these anomalies consistently plot along fold hinges, thrust ramps, dilation jogs and late-to-post-tectonic leucogranite intrusions, all features characteristic of fertile orogenic belts.
The structural setting—a saddle region of a moderate-to-gently inclined doubly plunging anticline dissected by deep-penetrating crustal structures—mirrors the geometry of Twin Hills and the fluid pathways that control mineralisation at Navachab.
The company’s geophysical and geochemical work across the licences is extensive.
Antler reports 4,956 line-kilometres of heliborne magnetics and radiometrics flown across the belt; 102.25 line-kilometres of induced-polarisation surveying across C1 and C2; 4,380 soil and calcrete samples collected across C2, C2 South and C2 extensions; and over 42 line-kilometres of geological mapping. At C1, the company drilled 2,861 metres of RC drilling during 2021.
Four holes intersected significant mineralisation: 1.2 per cent copper over forty metres from 29–69 metres; 11.2 g/t silver over forty-two metres; and 1.5 g/t gold over eleven metres from 11–22 metres.
Antler highlights that this polymetallic signature indicates a deeper gold-dominant system at depth, consistent with the architecture of the Kranzberg Fault Zone.
Further along strike, extension one under EPL 6408 is one of the highest-priority drill-ready targets.
The company notes that soil and calcrete anomalies here run for ten kilometres and are supported by coincident magnetic signatures interpreted as potential structural traps.
South of EPLs 7261 and 7960 hosts a seven-kilometre gold anomaly of 10–405 ppb gold and is situated directly southwest of Osino’s Twin Hills, sharing the same structural setting and lithological contact along the Karibib–Kuiseb boundary.
Antler emphasises that the Karibib–Kuiseb lithological contact is a recognised regional-scale control on mineralisation at Twin Hills, further elevating the prospectivity of C2 South.
The remaining licences—EPLs 8010, 7854 and C2 NE Extensions—remain untested but show strong magnetic and geochemical signatures.
Antler notes that these targets occupy the same structural corridors that have produced Namibia’s most crucial orogenic gold discoveries in the last three decades.
Taken together, Antler argues that the Kranzberg Fault Zone is not just a new structural observation but a possible new orogenic gold corridor in Namibia—parallel to and geologically analogous with the Karibib corridor that hosts Twin Hills.
The company says the structural controls, the deformation history, the anomalies, the historic workings and the early drilling results all point to a belt-scale gold system that has been overlooked until now.
