Projects
West Kimberley Metal's project areas were specifically designed to cover the most prospective ground for IRGS, PCG and IOCGs in North Queensland. The Walsh Project covers an area where parts of three metallogenic provinces converge upon each other (Figure 2), namely the Proterozoic Yambo Sub-province (Etheridge Province), the QLD Au Corridor (IRGS) and the Townsville-Mornington Island Igneous Belt (PCG, Base Metals, IRGS). The QGP1, QGP2 and QGP3 Project areas lie within the QLD Au Corridor, areas of which were selected based on the key selection criteria for WKM target styles observed within (see Exploration Concepts page).

Tenure
WKM's tenure is composed of 14 mineral exploration tenement applications, comprising 13 Exploration Permit Applications (EPMAs) in Queensland, and one Exploration License Application (ELA) in Victoria. Of the 13 EPMAs in Queensland, 10 are attributed to the Walsh Project, and one each for the QGP1, QGP2 and QGP3 project areas. The Victorian ELA covers the Hoddle's Creek project area. {Figure1, Table 1}. In all, WKM's project areas encompass a total prospective area of approximately 3472km2.

Project Targets
The Walsh Project (Figure 3) encompasses an area at the junction of three separate mineralized corridors, including the Proterozoic Etheridge Province, prospective for IOCGs, the Queensland Gold Structure, prospective for Intrusion Related Gold Systems, and the Townsville-Mornington Island Igneous Belt, prospective for Porphyry Copper-Gold deposits.
The Proterozoic and Palaeozoic geology of the project area is entirely overlain by an estimated 150-200m of younger Mesozoic and Tertiary cover sediments. WKM's search for mineral deposits in these terrains therefore depends initially on geophysical interpretation. In particular, geophysical signatures mimicking those of large examples of WKM's target styles, within the framework of the Key Selection Criteria (see Exploration Concepts page), have been identified, and form the basis for targeting.
WKM have defined numerous targets in the Walsh Project area, and a selection of key example targets, one each for IOCGs, IRGS and PCGs are shown below (Table 2, Table 3, Table 4):

WKM's QGP1, 2 and 3 project areas were selected on the basis of observed magnetic features considered analogous to those of Intrusion Related Gold Deposits. The geology of the project areas generally consist of Permo-Carboniferous intrusive and extrusive rocks, including members of the Scardon Volcanics in QGP1 and 2, and the Bally Knob Volcanics in QGP3. Mesozoic cover rocks are prominent in QGP1, while Siluro-Devonian granites are exposed in QGP2 and 3. QGP3 is extensively overlain by Tertiary Basalts. Selected IRGS target examples for each of these project areas are provided below (Table 5, Table 6, Table 7):

Hoddles Creek Project
WKM's Hoddles Creek Project, located ~60km east of Melbourne, was the center of extensive historic alluvial and hard rock gold workings, with gold produced periodically between the 1860's and 1940's. Little or no exploration work has been carried out since. Although little is known about the gold hosting deposit styles, locally, gold and/or tin occurrences have been previously identified as Intrusive Related systems (Beenak) and epizonal orogenic Au (Hoddles Creek). Gold was noted in some case to be related to Antimony (Sb) mineralization. WKM plans to review historic information and assess the potential for economically significant gold mineralization within the project area. Initial work will focus on searching for and compiling historic data, conceptualization and low-impact geological reconnaissance and surface geochemical sampling. The geology of the area is dominated by Silurian sediments of the Melbourne Formation in the north, and the late Devonian Tynong Granite to the south east, however a large portion is overlain by Tertiary basalts. |
