Otavi Mountain Land

The Otavi Mountain Land (OML), located in northern Namibia, is a historically prolific and geologically unique base metal region that forms part of the Damara Orogenic Belt, dating back to the Late Proterozoic era. This rugged terrain is composed primarily of metamorphosed sedimentary and volcanic rocks, creating ideal conditions for mineralization.

Geological Framework

The OML features a complex lithological assembly of dolostones, limestones, quartzites, phyllites, and marbles, overlain by later calcretised sediments. These rock units have undergone regional metamorphism and folding, resulting in structurally controlled zones that host significant concentrations of base and critical metals.

Mineral Endowment

The region is particularly noted for:

  • Copper, lead, and zinc mineralization, primarily in carbonate-hosted settings.

  • High-grade ore bodies with associated by-products such as silver, vanadium, and germanium.

  • Carnotite-hosted uranium and vanadium occurrences, often near surface in calcrete settings—relevant for co-product extraction strategies.

Historical production and known deposits in the region include:

  • Tsumeb Mine – world-famous for its complex mineralogy and high-grade copper-lead-zinc ores.

  • Kombat Mine – a past-producer with strong potential for redevelopment.

  • Grootfontein area – notable for its structural and stratigraphic complexity, ideal for MVT-style mineralization.

Modern Exploration and Opportunity

Despite its long history of mining, the Otavi Mountain Land remains underexplored by modern standards. Current exploration by Ubique Minerals is targeting both known historic occurrences and newly identified anomalies using modern geophysics, structural mapping, and geochemical analysis.

The proximity to infrastructure, mining-friendly jurisdiction, and widespread mineralization make OML a cornerstone of Ubique Minerals’ Namibian exploration strategy, offering potential for discovery of economically viable, multi-metal deposits that align with the global demand for both base and critical minerals.
