African Exploration Mining and Finance Corporation (AFEX), the first appellant, applied on 15 February 2010 for a coal prospecting right under section 16 of the Mineral and Petroleum Resources Development Act 28 of 2002 (the Act) in respect of portions of the farm Klippoortje 32 IS. The Regional Manager rejected the application on 10 March 2010 on the basis that Tavistock Collieries (Pty) Ltd (fourth respondent) held an old order coal mining right over the same land. On 29 March 2010, the Director General of Mineral Resources (second respondent), as delegate of the Minister, converted Tavistock's old order mining right into a mining right under the Act. Tavistock had lodged its old order mining right for conversion on 6 December 2007, pursuant to item 7 of Schedule II to the Act. AFEX and the Strategic Fuel Fund Association (SSF), the second appellant (which was the former holder of the right to mine coal on the property), applied in March 2011 to set aside both the conversion decision and the rejection of AFEX's prospecting application. The High Court dismissed the application on procedural grounds, finding that AFEX lacked standing, had failed to exhaust internal remedies under PAJA and the Act, and had not complied with time limits. AFEX appealed with leave. The dispute arose from a 2001 notarial mineral lease agreement between SSF and Tavistock. AFEX argued that Tavistock had failed to meet its mining obligations under clause 7.5 of the lease (requiring a mining rate of 1,600,000 tons per annum) in 2009, and thus had lost its old order mining right prior to conversion.
