Molopo Farms PGM-Ni

Molopo Farms PGM-Ni Project

  • Strategic licenses over ~60km of the western margin of the Molopo Farms Complex (“MFC”)
  • MFC was emplaced at the same time as the multi-PGM mine Bushveld Complex in RSA
  • MFC under-explored due to Kalahari overburden, but PGM’s and Ni-Cu discovered in several locales
  • Exploration will target both Bushveld type PGM-Chromite “reefs” and ultramafic-hosted Ni-Cu massive sulphid
  • Includes the basal most units prospective for PGM and Ni-Cu-Co mineralization
  • One Bullion will use state-of-the-art exploration methods

Best intersections:

3.25g/t PGM+Au,0.35%Cu, 0.60%Ni  over 1.24m near Bray,

1.8g/t PGM+Au with 1.73% Cr over 0.1m at Keng 

14.6%Ni and 870ppm Co over 0.3m at Keng


    One Bullion wholly owned subsidiary Aruba Holdings Pty. Ltd. holds two exclusive prospective licences; PL305/2016 and PL306/2016 for base, rare and precious metals as well as industrial minerals. The licenses cover 1,867km2 in southcentral Botswana between Jwaneng and Werda, on the RSA border. This licences cover a ~60km long portion of the western margin of the Molopo Farms Complex, and importantly appear to include the basalmost units prospective for PGM and Ni mineralization.


    The project licenses are accessible with a normal vehicle via tar road on the A20, a north south highway that turns off from the major A2 Trans-Kalahari Highway at Sekoma, between Jwaneng and Kang. A network of secondary roads and tracks through the bush link up all of the smaller villages and cattle posts. 4x4 vehicles can access all areas of the Project, as can drilling equipment.


    The infrastructure in the exploration area is modest with the major town Jwaneng ~ 80 kilometres to the east which provides shops, restaurants, hotels, fuel stations and a hospital. Sekoma is the nearest sizeable town about 30km from the Project, and has a fuel station. The major power lines in southern Botswana pass by ~30km to the north of the licenses.

    Regional Geology

    The Project covers a portion of the western margin of the 1300 km2 Molopo Farms Complex and is situated about 200 kilometres west of the coeval Bushveld Complex in South Africa.  Current thinking is that the MFC was emplaced by two sets of dykes forming two sub-lopoliths and sills.

    The MFC is made up by a well layered lower ultramafic sequence containing; chromite bearing hezburgite, olivine orthopyroxinite and dunite. The upper mafic layers consists of norite, gabbros and diorites with pegmatitic areas. Structurally the MFC consists of a folded, block-faulted and tilted lopolith now warped into a southwest-plunging syncline and divided into northern and southern lobes by the east-northeast trending Jwaneng-Makopong and northeast-trending Werda-Kgare shear zones. Parts of the intrusion and its roof-rocks were later eroded and unconformably overlain by Waterberg Group and Kalahari sands.

    Significant Past Exploration

    Previous exploration of the MFC in Botswana has mainly targeted the eastern margin where access was better at that time, and Kalahari overburden thought to be thinner.  Work by Gold Fields and junior Molopo Australia NL (with jv partner Inco) in the period 1985-92 demonstrated that PGM grades of ~1g/t over metre-length intervals were present in the northeast near Tubane, Bushveld-type “Critical Zone” mineralization was found in the southeast near Bray (best intersection 3.25g/t PGM+Au,0.35%Cu, 0.60%Ni  over 1.24m).  Interesting rocks and lower tenor mineralization more akin to the Great Dyke of Zimbabwe were found in the north, near Keng Pan, very close to the One Bullion licenses.

    Since that programme very little has been done however new company Kalahari Key has recently optioned their MFC project to AIM-listed African Battery Metals plc.  Their project is adjacent to One Bullion’s licenses and is targeting the shear zones/suspected feeder dykes through the centre of the MFC.

    Planned Exploration

    One Bullion plans to implement a program over the marginal areas of the MFC of:

    i)                 Comprehensive exploration and water borehole compilations (to get depth of Kalahari and bedrock type information)

    ii)                High-resolution airborne magnetics over the appropriate parts of each license to map the margins of the MFC

    iii)               Follow-up surface geochem surveys using MMI (mobile metal ion technology) or similar techniques

    iv)               Follow-up ground geophysics (EM for MFC targets)

    v)                Initial drill testing of the best targets generated from the above.

    2020 Work:


    1. Compile all past water borehole drilling for depth of Kalahari
    2. Airborne Mag-EM to map BIF, QFP’s and gabbros

        Upcoming Work:

        1. Follow-up MMI geochem
        2. Drill testing of conductors and geochem anomalies
