The proposal is to extend existing shell grit Reserve No. 41076 northwards to a total of 13.4 kilometres along the beach on the east side of L'Haridon Bight. The extended reserve would be about 197 hectares, more than seven times its current size. The proposal includes a change in extraction method from digging pits to "harvesting" the top 0.3-1.6 metres of shell grit.

Reserve No. 41076 is vested in the Shire of Shark Bay for the purpose of "Quarry (Shell Grit)" and is situated approximately 50 kilometres south-east of Denham. The reserve is located on vacant Crown land which is under the control of the Department of Land Administration and the subject of a pastoral lease.
