Troy Completes Acquisition of the Casposo Gold-Silver Deposit From Intrepid Mines Ltd

PERTH, WESTERN AUSTRALIA--(Marketwire - May 7, 2009) - Troy Resources NL ("Troy") (TSX:TRY)(ASX:TRY) -



- Troy has completed the acquisition of the Casposo gold-silver deposit in San Juan province of Argentina from Intrepid Mines Ltd ("Intrepid").

- The acquisition price of US$20 million was paid on closing with US$2 million remaining to be paid on the 6th month anniversary of first production. Troy has funded the acquisition from cash reserves.

- Troy has commenced looking at the potential to fast track the mine development utilising the gold plant it holds in storage in New South Wales, Australia.

- As part of the Casposo deal Troy has secured an experienced local exploration team and acquired a portfolio of extensional, "brownfields" and regional exploration targets.

Troy announces it has completed the acquisition of Intrepid Mining's 100% interest in the Casposo deposit in San Juan Province in Argentina (see Figure #1). Troy has funded the acquisition entirely out of cash reserves.

Troy's Executive Director, Ken Nilsson, who has been responsible for all of Troy's mine developments, has taken responsibility for the development of the Casposo deposit into a producing mine. The team of employees based in Argentina who work on the Casposo project have transferred with the acquisition and are now employees of the Troy Resources group.

Commenting on the closing of the transaction, Troy CEO Paul Benson said: "We are very pleased we have closed the transaction to acquire Casposo. Our focus now will be to develop a new fast track and low capital cost plan for the development of the deposit. We expect to be able to update the market on the new development plan in the September quarter. This is an important milestone for Troy. We are entering a new phase of growth which will lift Troy's annual gold production above 100,000 ounces of gold per annum."

Troy has a track record of building mines quickly, efficiently and at low cost, and this will be Troy's third mine in South America. In 2002 Troy's acquired its first mine, Sertao, as an in-situ resource and quickly sourced an appropriately sized second-hand plant in Australia that was refurbished and transported to Brazil. In addition, Troy completed an infill drilling program which increased reserves whilst awaiting shipping. Time from acquisition to first production was just 14 months with an initial capital of just US$8m. Plant construction including earth works took approximately 6 months.

Andorinhas, Troy's second Brazilian operation, was acquired as an in-situ resource in November 2006 and was developed by relocating the mill and plant from Sertao. As additional milling capacity was required, a second-hand mill was sourced from Western Australia. Following the acquisition Troy converted the resource to reserve status, constructed the processing facility and developed the open cut mine and poured first gold in March of 2008. Sixteen months from acquisition to first production with an initial capital cost of just US$16m. In mid 2007, Troy commenced development of the high grade Mamao underground mine which is now ramping up to full production.

With Casposo, Troy will look to similarly fast track development to bring it into production as quickly as possible. If Troy is able to utilise some or all of the gold plant it has in storage in Cobar, New South Wales, Troy anticipates that that would lower the capital cost and time of the mine development.

Casposo is a typical Low Sulphidation epithermal style gold-silver deposit where mineralisation is hosted within rhyolite breccias and andesite. Veins are typically banded quartz-chalcedony colloform - crustiform banded with quartz - carbonate infill. Mineralisation is associated with an assemblage consisting of quartz, chalcedony, adularia, calcite, illite, sericite and trace sulphides. Gold and silver occur as electrum, native silver, sulfosalts and silver sulphides.

Mineralisation at Casposo occurs along a 10 kilometre long west-northwest-east-southeast (N60 degrees W) regional structural corridor, with the main Kamila Vein system forming a sigmoidal set 500 metres long near the centre The main structural corridor consists of 2 parallel veins sets dipping to the southwest at -60 degrees to -65 degrees (B Vein & Inca Veins). A secondary mineralised trend comprises multiple north-south striking sigmoidal structures that dip to the west at -65 degrees (Aztec, AF, B North & MV1 - Mercado Veins). Ore shoots are typically lenticular bodies up to 200 metres in length and up to 15 metres wide.

Work completed included surface sampling and geological mapping, trenching and pitting, detailed trench sampling of the vein systems, reverse circulation and diamond core drilling, an airborne magnetic survey, ground gradient-array induced polarization (IP) and pole-dipole IP surveys as well as bulk sampling for metallurgical studies. A feasibility study, commissioned in 2005, was competed by Intrepid in March, 2007.

The latest Casposo Resource estimate was completed in July 2008 by AMEC International Chile. Open pit resources were contained within a Whittle pit shell using a gold price of US$760/oz. Resources below this were classified as underground resources with a cut-off grade of 3.5g/t Au-eq. Grade interpolation techniques were inverse distance weighted.

Surface mapping and sampling completed to date has identified a number of outcropping gold bearing vein systems on the Casposo tenements that require drilling. In addition, Troy has acquired a portfolio of regional exploration targets within the Casposo region that warrant additional exploration. All of these extensional, "brownfields" and regional targets will be reviewed in the near future and so that an exploration program to drill test the best can be developed.
