Project Proponent Reward Minerals Proposal description Reward Minerals propose to develop the Lake Disappointment Potash Project (located approximately 320 km east of Newman). The proposal is to abstract brine from sediments and use solar evaporation ponds on the surface of the lake to create the potash product. The proposal would disturb 7,250 ha of land which includes 437 ha of vegetation, with the remainder of disturbance to the surface of Lake Disappointment.
