D’Aguilar’s subsidiary Navaho Gold Pty Ltd (formerly Navaho Mining has exploration licence applications over an extensive new “Carlin Style” gold province in Queensland on the eastern edge of the northern section of Queensland’s Bowen Basin. The company has a total of 14 applications for Exploration Permit for Minerals (EPM) along almost 200 kms of strike, and covering some 3,800 sq kms between Clermont and Collinsville.
Carlin style gold mineralisation was typed near the town of Carlin in Nevada USA in the early 1980s. It occurs as the result of low temperature mineralised solutions precipitating gold, silver and sulphide minerals in porous limey, magnesian and carbonaceous sediments, which had been made porous by acid solutions emanating from nearby intrusions and fragmentation from fault activity. The mineralisation occurs in long structural corridors known as trends, such as the famous Carlin and Battle Mountain trends which host in excess of 200 million ounces of gold. The trends are important features which are the focus of the intrusions, faulting and mineralisation.
In the northern Bowen Basin area, Navaho Gold geologists have recognised a similar set of favourable parameters – limey and carbonaceous sediments and volcanic rocks in regionally extensive Coal Measures at the base of the Bowen Basin, which have been faulted and sheared to produce a porous and permeable host able to absorb mineralising solutions emanating from porphyry style intrusions emplaced in long and pervasive fault corridors, as occurs in Nevada.
