Doug Stone's Mary River Battery map, for gold prospecting and metal detecting in Western Australia. Doug Stone has spent around 40 years mapping Australia's goldfields, and his maps are field-checked and updated regularly. This map shows the old gold diggings, reefs and mines across the goldfield, along with the roads and tracks to reach them and the public land where you can prospect. A handy, affordable map to keep in the vehicle when planning a trip to a new patch or getting to know a familiar one. Always check access rules and hold the right prospecting licence for the area before you detect.
