Resources
The project carries two advanced prospects in the Hawkeye and Trapper deposits with an indicated and measured resource base totalling just over 130, 000 ounces of gold. The mineralisation exists in two distinct northeast striking, steeply west dipping zones that vary in thickness from 10 to 50m along strike. The ore bodies are displaced by several cross cutting faults. Gold mineralisation of the Trapper and Hawkeye deposits is associated with quartz veining located at the sheared contact between amphibolite and quartz biotite schist. Ore zones, defined at approximately 1 g/t Au, vary from 5 to 20 metres in width and although closed off to the north and south, are open at depth and down plunge. In general the quartz veins, foliation and relict bedding are sub vertical in both deposits and high grade shoots plunge asymmetrically steeply northeast and shallowly southwest.
Gold
The projects development will be achieved through several advanced gold prospects, including the Winchester, Trapper West and Blake prospects, which show resource potential and require additional RC and diamond drilling. Regionally, several BLEG soil anomalies wait drill testing and several significant RAB intersections, including 20 metres at 7.08g/t Au at Central Bore West and 5 metres at 2.76 g/t Au, 5 metres at 3.9g/t Au, and 9 metres at 2.30g/t au at Central Bore, require follow-up RC drilling.
Additionally the large tenure covers many mineralised regional structures over which target definition is incomplete and thus the potential exists for the discovery of new gold mineralisation.
Iron Ore
The Padbury Group’s Robinson Range Formation contains at least two 30 m thick bands of supergene-enriched Banded Iron Formation. The bands are separated by 30m of iron-rich shale; the Padbury Group’s Millidie Creek Formation. Active iron ore exploration in the district is focused on both units.
The district was last explored for iron ore in the mid 70’s and by 1974 less than 10Mt of goethite and hematite mineralisation was outlined. Improving commodity prices, improved market opportunities for junior companies, and several +60% Fe results in geochemical samples collected in the 1990’s by the Geological Survey of Western Australia, has rejuvenated exploration interest in the Robinson Ranges. The new enthusiasm for the Robinson Ranges was recently confirmed by Midwest Corporation, whose ground abuts the Three Rivers Project, has reported rock chip values ranging between 35 and 64.9% Fe. Midwest also report that deleterious elements are generally within acceptable limits: SiO2 <8.2%, P <0.17%, Al2O3 <2.9%.
The Three Rivers Project covers some 3.2 line km of prospective BIF in two tenements (E52/1364 and E52/1582).
