Through its subsidiaries, Rockfire Resources holds three Exploration Licences on New Britain island with a total area of 1,112 square kilometres. In addition to the currently held ground, the Company has three licence applications pending in New Britain.
Large ground holding on New Britain island along a zone of established potential for porphyry mineralization with known significant mineralised systems at Simuku, Plesyumi and Nakru. Known deposits nearby include Simuku deposit which contains a reported Inferred Mineral Resource of 200 million tonnes grading 0.47% copper equivalent
Since early-2014 Rockfires’s exploration has concentrated on the Tripela prospect where spectacular near surface copper mineralisation was discovered by our reconnaissance team.
By April 2015 almost 10,000 metres of drilling have been completed on the project.
Rockfire Resources holds three Exploration Licences on New Britain island with a total area of 1,112 square kilometres. In addition to the currently held ground, the Group has three licence applications pending.
The New Britain licences cover an area which straddles the so called Kulu-Fulleborn Trend, a NW-SE trending belt of mainly intermediate volcanic rocks and associated, sub-volcanic intrusives which host a number of historically reported porphyry copper mineralisation targets, particularly those at Simuku, Plesyumi and Nakru.
The main contiguous block of licences held and under application covers an irregular elongated shape between Kimbe, the capital of the West New Britain province, on the north coast, to Fulleborn on the south coast.
Kimbe has a deep water port that can be used to bring in vehicles and drilling equipment. The area around Kimbe is covered for the most part with oil-palm plantations and has a good road infrastructure and access to this area is therefore relatively easy. Apart from the area around Kimbe most of the Exploration Licence areas are covered by dense tropical rain forest with patchy areas of secondary growth where logging and subsistence farming has been carried out.
The central part of the main licence block is dominated by the rugged Whiteman Mountain ranges which have altitudes ranging from 200m to 1,830m above sea level at the highest point. Numerous rivers and streams dissect the area and drain to the north and south coasts from the ranges. Access to parts of EL 1462 is difficult and in some instances prospects can only be reached on foot or by helicopter. However the Mt Nakru area which includes our most advanced exploration targets at Tripela, Junction and Flying Fox has road access via a logging track.
The Rockfire team assembled a large database from previous exploration programmes on New Britain Island and followed this with a reinterpretation of all available geophysical data for the project area. This work produced a significant number of high priority target areas. Using the results of the studies, the Company embarked on a major field program in June 2010 to follow up and test a number of these targets. Our exploration teams completed widespread reconnaissance rock chip sampling, geological mapping and detailed, grid-based, geochemical soil sampling programmes.
By December 2012 more than 5,000 soil samples and more than 2,000 rock samples had been collected on the New Britain project. Mapping by our geological field team located significant copper mineralisation at a number of new locations where mineralisation had not previously been recorded. Subsequent fieldwork focused on the delineation of potential drill target areas. During 2013 three holes were drilled on geophysics targets in the Mt Nakru area, two at Junction and one at the Flying Fox target.
