Kraaipan Gold

Kraaipan Gold

  • Control over Botswana portion (~80km strike length) of western limb of highly prospective greenstone belt
  • Kalahari overburden has limited past work – will use modern methods to make discoveries
  • Harmony’s Kalgold Mine (~50,000oz/yr – 2Moz reserve & resources) along strike in RSA
  • African Rainbow’s Kalplats Deposits (~6.5Moz PGM resource) along strike in RSA

Kraaipan Greenstone belt in Botswana has seen very limited past work due to Kalahari sand cover – One Bullion will use state-of-the-art exploration to make discoveries

Two Major Deposit Types for Exploration:

1)  Gold in Banded Iron Formation (“BIF”) on Eastern Limb

    • Harmony’s Kalgold Mine (~50,000oz/yr – 2Moz reserve & resources) along strike in RSA actively exploring towards Botswana
    • Significant past near-surface exploration success in Botswana by Reunion Mining in 1997 (best intercepts 13m@1.71g/t, 5m@2.29g/t) and Laconia (ASX) in 2017 (best intercepts 6m@2.3g/t, 2m@1.72g/t)

2)  PGM + Au in Gabbro Intrusions of Western Limb

One Bullion’s wholly owned subsidiary Marcel Holdings Pty Ltd holds four exclusive prospecting licenses numbered PL006/2018 to PL009/2018, for base and precious metals as well as industrial minerals. The licenses covers 2,542km2 in southeastern Botswana adjacent to the border with South Africa. Prospecting Licenses are awarded for seven years with 50% relinquishments required after years 3 and 5.  Expenditure commitments amount to BWP 2,250,000 per license (~$C300,000) for the first 3 year period.


The Kraaipan Project is accessible by road throughout the year with paved roads and a network of secondary roads and tracks through the bush linking up all of the smaller villages and cattle posts. 4x4 vehicles can access all areas of the Project, as can drilling equipment.


The Project is in a relatively sparsely populated farming area of Southeastern Botswana, with the larger towns of Goodhope and Ramatlabama to the east, Kanye to the north and Mabule to the south. A number of border towns with South Africa are along the southern license boundaries, the Molopo River. The major power lines in southern Botswana run near to the licenses, and all major towns and villages are on the grid.

Regional Geology

The southern part of Botswana includes the Amalia-Kraaipan Group rocks deposited in the early Archean approximately 3.5 billion years ago.  There are three major greenstone belts or sectors known as Stella, Kraaipan-Goldridge and Madibe from west to east. The greenstone belts consists of banded iron formation (BIF), metavolcanics and metasediments, as well as gabbroic intrusives typical of major gold-producing greenstone belts such as those in Canada, Australia and Zimbabwe.  Major gold and PGM deposits are present in the Kraaipan greenstone belts on the South African side of the border, while the Botswana portion has not received nearly as much exploration due to Kalahari sand coverage.

The Kraaipan group is overlain by Kanye volcanics and Lobatse volcanics, with the Lobatse volcanics forming part of the Ventersdorp supergroup. This is followed by Transvaal sediments and Waterberg group, all mantled by Kalahari sand cover ranging up to 30-40m in thickness.

Significant Past Exploration

Previous exploration of the Kraaipan in Botswana has targeted the Kraaipan-Goldridge Sector of the greenstone belt where outcropping BIF is known, by Reunion Mining in the 1990’s, Discovery Metals in the 2000’s and Laconia Minerals in 2017.  These programs demonstrated that gold mineralization similar to that mined at Kalgold is present in similar grades and widths, but to date no resources have been established.  The Stella Sector of the Kraaipan has received little exploration in Botswana.

One Bullion Activities

Reconnaissance work was carried out in April focusing on the Stella greenstone belt and targeting regional magnetic high anomalies to find outcrop and mineralization. A drone was used to help locate outcrop within the regional magnetic features.  Being a semi-arid environment, calcrete is the predominant lithology on surface forming due to leaching of calcareous material in the Kalahari sands.

No confirmed outcrops were located on the property, however BIF exposures were found on graded road surfaces, emphasizing that the geophysically inferred greenstone belts are present.  Near-term exploration by One Bullion will include detailed high resolution aeromagnetic surveying of the licenses followed by systematic geochem sampling to locate areas of mineralization within the BIF and gabbroic rocks present.  Geochem anomalies will receive immediate drill testing with the Company’s rig to characterize the mineralization and assist with planning larger delineation programmes of ground geophysics (IP surveying) and drilling as warranted.

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
