SIOC and AMSA were co-holders of an 'old order mining right' in respect of iron ore on eight properties at the Sishen Iron Ore Mine, holding undivided shares of 78.6% and 21.4% respectively. The parties had entered into a Supply Agreement in 2001 whereby SIOC would mine iron ore on behalf of AMSA at cost plus 3%. When the MPRDA came into operation, SIOC lodged its old order mining right for conversion in December 2005 (relating to all Table I and Table II properties). In May 2008, the DG converted SIOC's old order mining right into a mining right under the MPRDA in respect of all the properties. AMSA failed to lodge its old order mining right for conversion before the expiry of the five-year period on 30 April 2009. After that date, ICT applied for a prospecting right in respect of iron ore on seven of the Table I properties, which was granted by the Deputy DG. SIOC also applied for a mining right in respect of the 21.4% share. SIOC challenged the grant to ICT, and AMSA sought declarations that SIOC had become the exclusive holder of the converted mining right.
