On 1 February 2006, Kwekwe Consolidated Gold Mines (Pvt) Ltd (KCGM) entered into a standard tribute agreement and rental agreement for Chaka Gold Plant with the Reserve Bank of Zimbabwe (RBZ) under the Mines and Minerals Act. The agreement had an initial 3-year term expiring on 2 February 2009, renewable for another 3 years to 2 February 2012. RBZ operated through its subsidiary Carslone Enterprises (Pvt) Ltd. When RBZ shifted policy to shed quasi-fiscal operations, Carslone continued under the agreement until expiration on 2 February 2012. On 15 December 2011, Carslone notified KCGM that the tributes and plant rental would expire in February 2012 and recommended Midkwe Mining Services as a replacement. After the agreements expired on 2 February 2012, Midkwe Minerals (Pvt) Ltd continued mining operations without any legal agreement. The Mining Commissioner confirmed on 29 February 2012 that the tribute agreement had lapsed and any person mining under the former agreement was contravening mining law. Two consolidated cases arose: HC 683/12 (KCGM v Carslone seeking to interdict unauthorized mining) and HC 800/12 (Midkwe seeking to interdict KCGM from disturbing its operations).
