Frontier Resources (ASX: FNT) is a junior mineral exploration company which aims to discover, delineate and develop gold, copper and base metal deposits in Papua New Guinea (PNG) and Australia.
The company is focused on the highly mineralised pacific "rim of fire" where it has a 100% interest in four Exploration Licences (1,140 square kilometres) and three Exploration Licence Applications (2,212 square kilometres) in PNG.
Frontier Resources (ASX: FNT) has reported that geophysical, geochemical & geological exploration programs are progressing well at the Andewa Gold Project (EL 1351), located near the north coast of the island of New Britain, in Papua New Guinea.
Rocks within the 9km wide crater show evidence of significant hydrothermal alteration, with five high-level gold prospects demonstrated within a 7 km by 2.5 km structural zone.
Peter McNeil, managing director, said the company believes the Andewa Exploration License has excellent potential to yield significant gold mineralisation with further exploration.
Frontier commenced the major exploration program at the Project in late June. The goal is to demonstrate a major gold mineralised system at Andewa, producing new and systematically defined, high quality trenching and drilling targets in multiple prospect areas.
An assessment has shown geological and mineralisation similarities to the Round Mountain Gold Deposit in Nevada (> 11 million ounces of gold produced), where the gold occurs on the rim of an ancient collapsed crater/caldera and is mainly fine-grained, with visible gold occurring in structural intersections.
The known gold mineralisation at Andewa is controlled by steeply dipping structures, structural intersections and possibly also low dipping favourable rock units.
Subject to the 2010 program results an extensive drilling program is planned for 2011. A very large grid (approx. 18 sq km) is now about 40% surveyed and cut for the geophysical and geochemical programs.
Soil and rock geochemical sampling is continuing and the first group (450 samples) have been despatched to the laboratory. About 3,000 samples are expected in total.
A very large 3D-Induced Polarisation geophysical survey commenced in early July and the company anticipates it to take about 3 months to complete the gridded area.
A ground magnetic survey will be undertaken concurrent with/subsequent to the 3D - Induced Polarisation.
When finalised, the data will allow a comprehensive geological, geochemical and geophysical assessment of the Andewa gold mineralised system and will define high-quality, coherent and coincident anomalies for further evaluation.
Frontier concentrated mostly on the Komsen Prospect, leaving 4 additional prospects plus large potentially mineralised areas still to be systematically explored.
Previous gold in trench assay results at Komsen include: 5.0m of 18.5 g/t, 3.7m of 12.6 g/t, 3m of 14.26g/t, 3.7m of 9.1 g/t, 5.0m of 5.0 g/t, 21.6m of 4.41 g/t and 9m of 6.44 g/t.
Visible gold was noted in 3 trenches and silver was anomalous at a 1:1 level (but with results locally as high as 1m of 155 g/t).
Many silicified /auriferous zones are also known proximal/peripheral to the Komsen Prospect and are under-explored.
The Ekhos Prospect is a 700m x 100m gold-in-soil anomaly, with gold occurring in quartz veins to about 10m width and associated with base metals.
The Pasgoi Creek Prospect consists of gold associated with patchy siliceous iron oxides and moderate clay alteration.
The Ler Creek Prospect consists of SW plunging gold bearing veins in a fault bounded breccia, with a peak rock chip assay of 41.7 g/t gold.
The Samarung Prospect had an anomalous float sample grading 37.2 g/t gold + 1.58% copper + 0.5 ppm platinum + 44 ppm palladium.
The Kehedie Prospect has had limited exploration conducted and consists of 3 gold (to 0.22 g/t) and arsenic soil anomalies over a 300m N-S zone.
The Tamo River Prospect consists of disseminated chalcopyrite, bornite and malachite mineralisation grading 0.35% copper in monzonite float.
Frontier Resources has purchased a diamond drill rig which will be used to help define the extent of mineralisation on the company’s PNG and Tasmanian properties and is expected to allow JORC compliant resources to be estimated as appropriate in the future.
