Great Artesian Basin (100% owned)

"The Great Artesian Basin is one of the largest artesian groundwater basins in the World and has significant reserves of heated groundwater suitable for a variety of geothermal applications."

Green Rock Energy has eleven exploration licences which occupy an area of approximately 5,038 km² in the Great Artesian Basin (GAB).

The GAB is one of the largest artesian groundwater basins in the world and underlies over 1.7 million sq kms, about one-fifth of Australian land area. The GAB contains artesian water held in permeable sandstone layers which are over 3,000 metres thick in the deeper parts of the Basin.

Objective

The Company aims to locate areas within its exploration licence with sufficiently high water temperatures and good natural water flow rates for emission free, renewable base load electricity generation.

Water salinity in the main aquifers is good with dissolved salts ranging from 0.5 to 1.5 g/litre. The GAB aquifers can deliver flow rates of up to 6ML/day (ie more than 2 Olympic sized swimming pools) without the need for pumping.

Activities to Date

Analysis and evaluation of existing data is underway with a view to targeting exploration wells to prove the required temperature and flow rate needed for power generation.
