domestic and international markets. The international market for Australian mineral sands, sold through Iluka resources, was mainly China, where 80% of exports are used as pigment in paints. A 2010 KPMG assessment, commissioned by Sibelco Australia, found 95% of revenue from NSI sand mining stayed in the Australian community. Environmental concerns push for closure In 1991, up to 100,000 litres of diesel spilled from the sand mining company, Consolidated Rutile Limited [CRL] into Amity wetlands. This was not reported until 1994, the same year CRL was awarded a commendation in the inaugural State Government Award for Environmental Excellence. It was not until 1997 that the incident was acknowledged in CRL's Annual Report stating that the spill was expected to be cleared by 1999 – eight years after it occurred. The sand mining company was never fined by the Department of Mines and Energy for these environmental incidents and continues operating. In 2008, CRL received the Premier's Environment Protection Agency Sustainability Award for Resources industries for its rehabilitation processes. The award is given to a company that demonstrates leadership in environmental practices and commitment to progressive rehabilitation and long-term sustainability. At that time (according to the Stradbroke Island Management Organisation [SIMO], an environmental watch-dog organisation) two-thirds of the island were covered by mining leases. In late 2009, CRL, which became a subsidiary of Unimin Australia, itself a subsidiary of Sibelco, after being purchased from Iluka Resources, was charged with illegal sand mining after it was alleged to have sold sand extracted from the island, to the building industry for the production of glass without the correct permit. Sibelco appealed, on technical grounds, the Magistrate's decision that it had a case to answer on the criminal charges for the illegal selling of sand. On 22 May 2014, the Court of Appeal heard the appeal and delivered its judgement, all on the same day. It dismissed Sibelco's appeal against criminal proceedings. The final day of this now five-year-long criminal trial was scheduled for 22 August 2014, in the Warwick Magistrates Court. In 2009 it became public knowledge that the mining leases on North Stradbroke island had also expired for the areas of operation of the Enterprise and Yarraman Mines. This led to the June 2010 announcement by the then Premier Anna Bligh that sand mining on the island would be phased out by 2027 and the mined land and Ramsar listed wetlands would
