The final go-ahead for the $48 million Jangardup mineral sands project will provide an employment and economic boost for the South-West.
Deputy Premier Ian Taylor said the Cable Sands project would create about 100 jobs during the construction phase and 96 jobs when in operation.
"The start of the project comes after agreement was reached between the State Government and the company on transport routes," Mr Taylor said.
"The company will be responsible for 70 per cent of the costs up to a total of $6 million of building the Nannup by-pass road and upgrading sections of the Vasse Highway and Stewart Road - the Government will meet the remaining costs."
Mr Taylor said the company had advised the Government that it would commence site preparation and some construction work this summer.
The work would extend through to autumn of 1994 and the first deliveries of finished product were expected to occur in the third quarter of 1994.
When in full production, the operation would produce about 200,000 tonnes of ilmenite per annum.
"The Minister for the Environment has approved the heavy mineral transport program which would involve use of the highway through Nannup until the bypass road was completed," Mr Taylor said.
"Work on the bypass will be managed by Main Roads and be completed as soon as possible.
"Part of the agreement is that the company will participate in a management committee to be set up and chaired by a representative of the Commissioner of Main Roads to oversee the road improvement program.
"The committee will have representation from the company, Main Roads, Department of State Development, the Nannup Shire Council and the South-West Development Authority.
"The project will provide much needed jobs for the region, boost the exports through Bunbury harbour and provide a further economic stimulus to the State."
