You can use the posted co-ordinates (above) as a waypoint. It is a pleasant, open spot for a break or lunch.
At the WP there is a 6' diameter by 20' long boiler, 2 of brick steeling pits & lids, 1 of large dam, pipework and some building foundations. South of the WP is an area of sand that is frequented by motorbike riders. North West of the WP, across the road, is an area of extensive mineworks. Some of the mines are open and deep so care should be taken if taking pets/children to the site. In 2012 a man was rescued from 1 of these mines.
