However, stories continued circulating: allegations that he was Robert Mugabe's right-hand man, that he had bribed Kabila into securing his mining concessions, and that his mines were financing Zimbabwe's soldiers in the DRC. To date, there have not been any substantiation on claims of Rautenbach's links to Mugabe and the European Union struck him off the targeted sanctions list in February 2012. In June 2018, Rautenbach, owner of Zimbabwe Bio Energy (ZBE), became embroiled in a legal battle with joint venture stakeholders at Nuanetsi Ranch Limited, who are accusing Rautenbach of "sabotage, looting and making unilateral decisions without the consent of Nuanetsi Ranch Board". Rautenbach has significant game-ranching investments in Mwenezi, but his company, ZBE, currently faces numerous allegations relating to the "abuse of workers, arbitrary dismissals and non-payment of salaries". The 308,000 hectare cattle and wildlife management ranch is a trust property, established by former Vice President, Dr Joshua Nkomo. In a letter to Zanu PF spokesperson, Simon Khaya Moyo, Nuanetsi Ranch chairperson, Dr Liberty Mhlanga, condemns Rautenbach's alleged misconduct: "We have taken Billy to High Court to seek his urgent eviction because he is looting Nuanetsi Ranch's cattle and wildlife without consulting my Managing Director whom he should be working with on the Ranch [...] He has continued to loot and destroy the Ranch. I am not sure where his power is from", reads part of the letter, which is dated 4 April 2018. In favour of sustainable development, Rautenbach saw to it that CAMEC created employment for over 5,000 people at its Luita plant. At an average of five people per household, 25,000 people are currently being sustained as a result of this operation. The latter also saw the completion of an expatriate staff village of 3,000 people – fondly known as Billyville by employees and contractors – with over 200 houses, recreation facilities, staffing hostels, and a 2,000 m2 office complex. Moreover, millions of dollars were reinvested into the DRC to uplift the communities surrounding CAMEC's operations. These projects included renovations to a clinic and the provision of necessary medical equipment, and the construction of a crèche and primary school. Construction also included a technical college to educate 3,600 children in the skills needed at the processing plant such as mechanics, electronics and welding to help alleviate the skills shortages in the DRC.
