The Horry Copper Project is comprised of one exploration license; E80/5313. The area of the project is 1 BL (3.25 km2). Halls Creek is located approximately 90km to the north-east, Broome is around 530km to the west, and Kununurra is approximately 380km to the north of the tenement.
The project lies within the Halls Creek Mobile Belt, which is a major deformation, multiple fault zones bounding the eastern edge of the Kimberley Craton. A tertiary duricrust or laterite is widespread in central and western parts of the project. These, often sand-covered areas, obscure the underlying geology but the aeromagnetics have enabled a reasonable understanding of the sequence.
Multiple historical high-grade copper and gold workings occur across the project area. Sporadic mineralisation over 7.4 m width and 900 m long shear zone were identified during field mapping and prospecting mineralisation.
The historical work carried out is limited in nature but demonstrated that newer geophysical mineralisation indicators can now be utilised to identify prospective zones undercover. Further exploration is warranted including a review of previous work, geological mapping and additional rock chip sampling along with further geophysical surveys to identify potential drilling targets.
Several major regional structures are evident which affect the stratigraphy. The Springvale and Laura River Faults are north-north-east trending zones which can be traced over hundreds of kilometres. At their southern extremities, these structures appear to swing south-westerly and merge into the cast-west fault systems of the King Leopold Belt.
Between the Springvale and Laura River structures, many secondary faults and shear zones arc observed with two distinct quartz filled features defined as the Mt Carmel and Mt Hawick Faults. The Mt Hawick Fault is marked by prominent quartz ridges and silicified sediments and appears to form the contact between dominantly Biscay Formation to the west and Olympia Formation to the east (Multi Metal Consultants Pty Ltd, 1996, EL 80/2035A).
In the southwestern region of the tenement Palaeozoic cover is fault-bounded on the eastern boundary, consisting of Antrim Plateau Volcanics, Tally Conglomerate, Lubbock Formation, and the McAnally Shale. The aeromagnetic signature of the underlying geology is like the outcropping BIF units in the central region of the tenement.
Multiple historical high-grade workings occur across the project area. The previous prospecting for nuggets at Leo Prospect has identified up to 32oz Au with the largest reported nugget being 8oz.
Cu-Au-Ag mineralisation occurs in the gossanous quartz vein within the shear zone; high-grade zone about 60 m long and 2.4 m wide but sporadic mineralisation over 7.4 m width and 900 m along shear zone were identified during field mapping and prospecting.
Panorama Resources NL conducted field mapping and soil and rock chip sampling during the 1995-1996 period. Brown Dog NL conducted rock chip sampling on the area from 2000 to 2001 with 6 samples collected on the current project area with some high Cu results.
Proposed Exploration Program
The Company plans on undertaking further exploration at the Horry Copper Project including a review of previous work, geological mapping and additional rock chip sampling along with further geophysical surveys to identify potential drilling targets.
Based on the outcome and results of the geological mapping, geophysical surveys and rock chip sampling, the Company will undertake exploration drilling in and around the known mineralised targets and extend along strike to identify and delineate additional mineralisation.
