The Lanjanina concession lies in the south-central part of Madagascar approximately 180 kilometres ( 258 road km.) south of Antananarivo and 35 km ( 55 road km.) west of Ambositra, and covers an area of 156 km2 (15,600 hectares).

Following two earlier reconnaissance programs in Lanjanina, the Company is continuing with a programme of stream sediment and soil sampling and follow-up geophysics in the area throughout 2005. The geophysics comprises of magnetic and induced polarization (IP) surveys. The programme is anticipated to identify targets for drilling.

The Lanjanina licence area comprises of two distinct geological terrains. Firstly, the intrusive Itsindra Massif to the west and, secondly, the Itremo meta-sediments and later intrusives to the center and east.

The oldest rocks are basement orthogneisses, which are overlain by a quartzite, schist and carbonate series of meta-sediments. Tectonism has resulted in schists and marbles conformably being intruded by large volumes of basic magma resulting in the lopolithic, gabbroic, noritic Itsindra Massif.

Mineralisation within the area is divided into two broad categories conforming to the two geological terrains. The first are the basic rocks of the Itsindra Massif (Lanjanina), a relatively homogenous intrusion of noritic gabbros. Previous exploration identified copper, nickel and platinum group elements in geochemical soil samples and one drill hole located copper and nickel mineralisation within pyroxenites and to a lesser extent gabbros and amphibolites.

The second mineralised terrain is the calcareous meta-sediments in the Pachoud Mine area hosting skarn type copper, lead, zinc and molybdenum mineralisation. The mineral assemblage is complex and in decreasing order of abundance includes chalcopyrite, cubanite, bornite, molybdenite, magnetite, pyrite, cobaltite, pyrrhotite, pentlandite, galena, stannite, electrum, chalcocite, cuprite and malachite. Mineralisation is predominantly within the marble.

The Pachoud area concession includes the old (1884 to 1918) near surface Pachoud copper mine. The company’s earlier reconnaissance showed assays ranging from 3.6% to 17.5% Cu in grab samples of variously oxidised mineralized from the area and other nearby old mine workings at Jamet mine.

The Geological Service of Madagascar’s data review in 1972, estimated the Pachoud area to contain a ‘probable reserve’ of 17,000 tonnes copper in 900,000 tonnes ore grading 1.9% Cu. At prices recently of around US$3,500 this resource would haven in-situ value of US$60 million.

The Company’s reconnaissance of the Pachoud area suggests the potential for significant addition to this copper tonnage and identifies the Pachoud region as a highly prospective exploration target with the potential to host large near surface copper mineralisation.
