Precious and Base Metals Project, Western Australia (100% Laconia – excluding Manganese & Iron)

Barramine is a significant precious and base metals project located 245km southeast of Port Hedland in the east Pilbara region of WA. It is 100% owned by Laconia and comprises tenements E45/3312, E45/3233, E45/3234 over an area of 430km2. Together with the Lennons Find and Yandicoogina projects it confirms Laconia as a significant ground holder in the east Pilbara.

Laconia has identified four primary base metal and gold drill target areas at the project, and aims to drill these targets as part its 2012 exploration season.

Also, Laconia received a $150,000 grant for Barramine in June 2011, in a co-founding arrangement under the WA State Government Exploration Incentive Scheme. Under the grant it will match the $150,000 funding grant on a dollar-for-dollar basis on direct drill spending.

Geological overview

The project is underlain by the Archaean Gregory Range Inlier to the south and by Permian Paterson Formation fluvioglacial sediments of the Canning Basin to the north. The Gregory Range Inlier constitutes the northeastern most exposure of Archaean rocks in the Hamersley Basin. Upper Archaean units exposed at the Barramine Project include volcanics and younger epiclastic and chemical sedimentary units of the Jeerinah Formation.

The overlying Hamersley Group is represented by the Carawine Dolomite, which rests on the Jeerinah Formation sediments. The dolomite is well-bedded, crystalline and contains rare stromatolites. It lies within the core of an open north-south trending syncline. Pinjian Chert overlies the dolomite and comprises bedded chert and locally chert breccia.

The geological position of the project incorporates, and is also along strike from a number of base metal deposits including; Barramine, Camel Hump, Ragged Hills and Braeside. The discovery of anomalous copper and zinc in highly altered, pyritic acid volcanics by previous explorers has provided a prospective geological environment for base metal mineralisation.

Geophysical data and interpretation from the project area has indicated a number of electromagnetic (EM) anomalies. Laconia is targeting volcanic related base metal sulphide horizons within sediments.
