The Redcastle area is located in the central portion of the Archaean Norseman to Wiluna greenstone belt. This belt hosts numerous world class gold, nickel, lithium, rare earth and copper-zinc deposits. The rocks range from ultramafic to felsic volcanics, plus sedimentary rocks of all types, and later granitoids and dolerite dykes. These ancient rocks have been subjected to several periods of folding and faulting, resulting in a deformed lithological package.
Gold mineralisation in the region occurs in a variety of settings, commonly structurally controlled and near rocks of contrasting strength or mineral composition. Very commonly gold mineralisation is controlled by shear zones, with mineral alteration such as chlorite, sericite, pyrite, and quartz veining. These zones can have dips of any angle, but are commonly steep. The most famous of the mineralised structures at Redcastle is the Redcastle Reef. This is a gently curved structure occurring along the axial plane of a near east west fold that has an extensive strike length (almost 5km). This structure is crossed almost at right angles by the Redcastle Anticline.
The Redcastle Reef is a steep dipping zone of chlorite alteration that has several sub parallel zones of mineralisation. Many of these remain relatively surprisingly unexplored.
The company has developed a two year exploration budget which is designed to better explore the project than in the past. The aim is the discovery and definition of open pitable gold resources that could lead to a development opportunity. The proposed work and budget has been reviewed by the author and is considered to be well thought out and appropriate for the project. The program and budget is presented below.
