Minera IRL: a golden<br />

opportunity in Peru<br />

Minera IRL Ltd is a Jersey-registered<br />

gold-mining company listed on the<br />

London (AIM), Lima and Toronto<br />

stock exchanges with business units,<br />

compris ing all 100%-owned projects, in<br />

Peru and Argentina. With its head office in Lima, Peru, it<br />

operates the Corihuarmi gold mine and is carrying out<br />

feasibility studies on the Ollachea project and the<br />

company’s next gold mine, Don Nicolas in Argentina.<br />

In less than 10 years, Minera IRL has grown a resource<br />

base that has a current inventory of 1.8Moz in the<br />

measured and indicated categories, plus 1.4Moz in the<br />

inferred category.<br />

The Corihuarmi concession, in the high Andes of<br />

Peru, was acquired in 2002 and was taken through the<br />

discovery, feasibility and permitting stages before<br />

raising funds with the 2007 AIM IPO to build the mine.<br />

Corihuarmi began production in 2008 as an open-pit,<br />

heap-leach operation and made a return on capital<br />

within seven months. Current production is about<br />

33,000oz/y at a cash operating cost of US$400/oz. All<br />

gold is sold at the prevailing spot price. Corihuarmi has<br />

a projected mine life into 2015.<br />

The Ollachea project, the company’s flagship, is an<br />

Orogenic gold deposit acquired from Rio Tinto in 2006,<br />

located on the eastern escarpment of the Andes in<br />

southern Peru. Logistics and infrastructure are excellent<br />

as the deposit lies very close to the new Inter-oceanic<br />

highway, readily available hydroelectricity and<br />

adequate water.<br />

Company profile<br />

Following the negotiation of a comprehensive<br />

surface rights agreement with the local Ollachea<br />

community, exploration started in 2008 and rapidly<br />

resulted in a major gold discovery. A positive scoping<br />

study carried out in 2009 led to a pre-feasibility study,<br />

completed in mid-2011. The pre-feasibility study is<br />

predicated upon an underground mine and conventional<br />

treatment plant with a capacity of 1.1Mt/y. The<br />

production schedule is projected to recover over 1Moz<br />

of gold during a nine-year mine life.<br />

The projected economics are compelling and a full<br />

feasibility, currently in progress, is expected to be<br />

completed during Q3, 2012. A 1.2km-long exploration<br />

drive into the deposit is beginning and will allow<br />

further exploration of the eastern strike extent of the<br />

deposit from underground.<br />

The Ollachea deposit remains open-ended along<br />

strike in both directions and down dip. The NI43-101compliant<br />

resource inventory has already increased to<br />

10.7Mt grading 4g/t gold containing 1.4Moz in the<br />

indicated category plus 13.7Mt grading 2.8g/t gold<br />

containing 1.2Moz in the inferred category. Drilling<br />

from surface with two diamond rigs continues to probe<br />

the deposit.<br />

A feasibility study is nearing completion on the Don<br />

Nicolas project in the Deseado Massif in Patagonia,<br />

Argentina. This is predicated upon a high-grade<br />

measured and indicated resource of 1.5Mt grading<br />

6.0g/t gold, containing 280,000oz and 13.4g/t silver,<br />

containing 630,000oz. The project will be based on an<br />

open-pit and conventional gold treatment plant with a<br />

capacity of 1,000t/d.<br />

Extensive exploration is also being carried out by<br />

Minera IRL in Peru and Argentina. The company holds<br />

an extensive 270,000ha tenement package in the<br />

Deseado Massif which has already resulted in a<br />

discovery announced at Escondido in 2010. In Peru,<br />

exploration continues at Ollachea and nearby the<br />

Corihuarmi mine, including the Bethania gold-copper<br />

porphyry project.<br />

A key aspect of Minera IRL’s business is the<br />

comprehensive community programme at Ollachea<br />

and Corihuarmi in Peru. Programmes include health,<br />

education and sustainable development projects.<br />

The company also practises ‘World Best Practice’<br />

environmental programmes.<br />

Minera IRL is well poised to grow rapidly, with its<br />

increasing resource base, an excellent track record in<br />

exploration success and its team of mine developers<br />

and operators with a proven ability to discover<br />

and develop mines in South America.<br />
