Executive summary Reward Minerals Limited Lake Disappointment Potash Project is located within the Little Sandy Desert, approximately 138km south of Telfer and 285km east of Newman, in the Pilbara of Western Australia. The Lake Disappointment Potash Project initially comprised of two stages of activities: Stage 1-track development, exploration camp construction and infill drilling; and Stage 2-development of pilot ponds/trenches on Lake Disappointment. Development of the access track and exploration camp were completed in 2014. Infill drilling on the lake commenced in 2015 and is ongoing. Approvals for development of the pilot ponds/trenches (Stage 2 activities) are currently being processed and
