Leobam Holdings operated the copper producer Mowana Mine from April 2017 until December 2018 after it revived it from yet another liquidation dating back to 2015.
Cradle Arc Plc. owns a 60% stake in Leboam Holdings Proprietary Limited, and the remaining 40% of the ordinary shares are owned by ZCI Ltd.
In 2018, Leboam Holdings ran into financial difficulties and was unable to pay its debts.
Following a meeting of creditors of Leboam held on the 25th of February 2019, pursuant to the Provisional Order, the Botswana High Court issued a Final Judicial Management Order for Leboam (the “Final Order”). The Final Order became effective on 28 February 2018 and accordingly, subject to the supervision of the Botswana High Court, Leboam was placed under Judicial Management.
The Judicial Management of Leboam remains ongoing at present. Discussions on restructuring of Leboam Holdings, a company that operates the mine are currently ongoing between creditors.

Summary:
The Mowana Copper Project is hosted within north-northeast striking, steeply east dipping carbonaceous and argillaceous metasediments of the Matsitama Metasedimentary Group which are enclosed within foliated granitoids of the Mosetse Complex.
Hypogene sulphide mineralisation occurs within sub-vertical epithermal quartz-calcite vein breccias containing predominantly chalcopyrite + pyrite ± galena and sphalerite mineralisation. Hypogene mineralisation is capped by secondary oxide and supergene copper enrichment up to depths of approximately 50m and 150m below surface respectively. This in turn is overlain by Phanerozoic Karoo Supergroup siltstones, conglomerates and local tillite over the north and west areas of the deposit with depths varying from 1 to 90m. Regolith cover over the southern extent of the deposit generally consists of shallow (1 - 3m) clay rich black soils.
The metasediments hosting the deposit occur parallel to and within the northern extent of the 200km long north-northeast trending regional Bushman lineament exhibiting thicknesses variable between 200 to 400m mostly due to large scale pinch and swell amplitudes of up to 600m. However, the contact between the footwall sediments and the western granitoid has not been intersected in any of the historical or recent drilling.
Four deformation periods have been interpreted within the project area, the strongest and most significant with regards to veining and mineralisation being th ........

Summary:
The production rate of the Mowana Mine is planned at 1.2Mtpa.
