+120 year mining history

STABLE & MINING FRIENDLY

  • Stable democracy, independent judiciary, diverse economy

  • Transparent system of mineral & surface title

  • Strong political and social support of mining with stated ambitions to develop mineral resources

    EXCELLENT INFRASTRUCTURE

  • Excellent physical & social infrastructure

  • Within 20km's of essential utilities, roads, grid power, water supply & well-serviced towns

    WELL-ESTABLISHED MINING INDUSTRY

  • Major revenue earner & employer

  • Stable tax code and fair fiscal terms

  • N$ sovereign bonds trading at 8.3% YTM, comparing well to other favorable mining development jurisdictions such as Botswana (10.2%), Mexico (7.8%), and Brazil (9.7%) for similar maturities





  • Haib is a large, world-class, advanced open-pit Cu/Mo porphyry deposit with a long history of exploration & project development

  • One of a few Paleoproterozoic porphyry copper

    deposit in the world (two in Namibia).

    Excellent pedigree (Falconbridge, Rio Tinto, Teck) with a long history of exploration & project advancement



  • Due to its age (1.9Ga), multiple metamorphic and deformation events, but classic mineralization and alteration features typical of these deposits remain.

  • Mainly chalcopyrite with minor bornite and chalcocite present

  • Comparable size & grade projects in younger belts; Pebble (Alaska), Warintza (Ecuador). Tier 1 examples often have significant supergene enrichment; Escondida (Chile)

    Orange river water pump station, pipeline & site water storage dam

    Existing Grid power close to site (to be upgraded)

    Grid Power

    • Application for NamPower to conduct a capacity assessment to connect to the 220kV line 45km from the plant site

    • 150MW power demand sufficient grid power available from SA grid via Namibia
    • PV, wind power assessment underway

      Water Supply

    • 20m m3 pa water demand for a 20mtpa plant. Various supply scenarios:
    • Orange river source: (9km) plus on- site water storage in attenuation dams - capacity for up to 6 month's water storage
    • Neckartal dam alternative: (230km pipeline) backup / growth option being advanced
