Background and Geology
The Abydos project comprises of eight exploration licences which are Mineral Rights Tenements, in the Pilbara region of Western Australia. The project is considered prospective for Archaean lode gold deposits, VHMS base metal mineralization (associated with rocks of the Sulphur Springs group), Shaw River has identified geochemical targets for further exploration.
The tenements are currently being explored by Atlas Iron for iron ore in the Pincunah Greenstone Belt.
The Abydos East project is located 110km south of Port Hedland and is comprised of two tenements E45/2362 and E45/2496 covering a total area of 234km². The project area includes a significant portion of the Strelley granite, and the Sulphur Springs group on the western side of the granite. Shaw River has undertaken soil sampling and outlined a series of zinc-rich base metal prospects within the Leirla Formation. Rock samples up to 1.44% zinc and 4.4% copper have been returned from the Tojo prospect. A second set of copper-gold prospects have rock chip results up to 11.1% copper, 1g/t gold and 54g/t silver. Previous drilling at the Price of Love prospect gave drill intersections up to 11m at 1.43% copper and 0.25g/t gold.
Historical mining in the area includes the Lynas Find goldfield (+140,000oz mined) and the Lallah Rookh Gold Mine (31,900oz mined). The eastern tenements of the group include rocks of the Sulphur Springs Group, which host the Sulphur Springs VHMS deposit (10mt @ 3.5% Zn and 1.5% Cu), just 8km to the east. Historical information shows the presence of multiple known occurrences of gold, base metals (copper-zinc-lead and silver), nickel and PGE anomalism across the tenements being acquired.
The Abydos project lies approximately 110 kilometres south of Port Hedland, conveniently straddled by the Newman highway and Newman railway line. This area is extremely accessible by road and rail in close proximity to Port Hedland.
Exploration results and sampling highlights include:
- Active exploration programs were conducted at Abydos during 2008, focusing on copper-gold and base metal mineralisation trends identified in extensive historical exploration review.
- High grade rock chips up to 11% Cu, 54g/t Ag, 1.6g/t Au and soil samples up to 0.23% Zn, 0.14% Cu and 1.3g/t Au indicate extensive new copper-gold-base metal trend up to 21km in length.
- Infill soil sampling results with up to 0.1% zinc, received during the December 2008 Quarter confirm the presence and location of up to 4 excellent, large, discrete Zn-Cu-Ag-Au VHMS targets.
- Soil and rock chip sampling, as well as detailed geological mapping and alteration analysis has generated prospective targets for gold, copper-gold and zinc-copper suitable for drill testing.
During 2010 Shaw commissioned a detailed review of its base metal and gold portfolios by Tony Morgan of Mincorp Consultants. The completed base metal & gold review document will allow Shaw River to finalise investment options for its 100% owned Pilbara mineral projects, although for the medium term the focus will continue to be on its highly prospective manganese portfolio.
Historical data compilation was completed during the period. During the period an Option to Purchase Mining Rights over Part Exploration Licence 45/2363 (Abydos Project) between Atlas Operations Pty Ltd (iron ore rights), Shaw River (mineral rights) and Altura Exploration Pty Ltd was concluded.
