Nullagine Gold has long been sought. Conglomerate rocks make up most of the hills surrounding Nullagine. The Mosquito Creek Formation is a succession of Archaean siliciclastic rocks that occupies much of the central part of the MCB in the northern part of the Archaean Pilbara Craton of Western Australia. The formation is deformed and has been metamorphosed under low-grade (sub-greenschist to greenschist) conditions.

Shallow geothermal energy – high efficient heating and cooling of hotel complexes and commercial buildings with borehole heat exchanger systems as seasonal storage for heat and cold The utilization of shallow geothermal energy with borehole heat exchangers and heat pumps for heating and cooling of buildings is very popular in Europe due to low costs of operation and high operating reliability. These systems have the highest rates of growth of all energy supply systems in Europe. In order to provide a productive and comfortable climate for a living and working environment, buildings have an anti-cyclical demand of heat and cold. During the summer, when abundant heat is available, they have to be air-conditioned, while in wintertime, when cold is at disposal, the buildings have to be heated. Especially the heat and cold supply for hotels and commercial buildings is a challenge, as their huge energy demand needs to be satisfied with a reliable and cost-effective solutio...
