43-101 Disclosure Statement

Information Concerning Estimates of Mineral Reserves and Resources and Exploration ResultsThe mineral reserve and resource estimates reported in this presentation were prepared in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”), as required by Canadian securities regulatory authorities. For United States reporting purposes, the United States Securities and Exchange Commission (“SEC”) applies different standards in order to classify mineralization as a reserve. In particular, while the terms “measured”, “indicated” and “inferred” mineral resources are required pursuant to NI 43-101, the SEC does not recognize such terms Canadian standards differ significantly from the requirements of the SEC Investors are cautioned not to assume that any part or all of thesuch terms. Canadian standards differ significantly from the requirements of the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories constitute or will ever be converted into reserves. In addition, “inferred” mineral resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian securities laws, issuers must not make any disclosure of results of an economic analysis that includes inferred mineral resources, except in rare cases.

The reconfigured mineral resources and the underground mineral resources presented in this presentation, the mine plan presented in this presentation, the proposed process flow chart in this presentation and the overall preliminary economic evaluation presented in this presentation has been reviewed and approved by Mr. Rodrigo Mello, Senior Geologist with NCL Ingeniería y Construcción S.A., Santiago, Chile a “qualified person” as that term is defined in National Instrument 43-101 and Guidance Note for Mining, Oil and Gas Companies issued by the London Stock Exchange in respect of AIM companies, which outline standards of disclosure for mineral projects. The particulars of the resource update are included in a press release dated July 15, 2010, and the particulars of the preliminary economic evaluation are included in a press release dated March 18, 2011, both of which are available at www.sedar.com.

The metallurgical information presented in this presentation has been compiled and approved by: on the underground option - John Wells, metallurgical consultant and a “qualified person” as that term is defined in National Instrument 43-101 and Guidance Note for Mining, Oil and Gas Companies issued by the London Stock Exchange in respect of AIM companies, which outline standards of disclosure for mineral projects; on the open pit/heap leach option - Jack McPartland, president of McClelland Laboratories, and a “qualified person” as that term is defined in National Instrument 43-101 and Guidance Note for Mining, Oil and Gas Companies issued by the London Stock Exchange in respect of AIM companies, which outline standards of disclosure for mineral projects. The particulars of the metallurgical update are included in a press release dated July 15, 2010, which is available at p j p g p p y , ,www.sedar.com.The exploration results presented in this presentation were reviewed and approved by Frederick Felder.

• Project is currently being reconfigured as an underground operation.

Mineral resources that are not reserves do not have demonstrated economic viability. A Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physicalcharacteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation ofthe economic viability of the deposit. An Inferred Mineral Resource is that part of a mineral resource for which quantity and grade can be estimated on the basis of geological evidence and limited sampling andreasonably assumed, but not verified, geological and grade continuity. An Indicated Mineral Resource is that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics,can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit.

Looking Ahead

Underground development was originally considered to follow open pit project

All i f t t t id f P h ldAll infrastructure outside of Paramo should allow rapid permitting

Future open pit potential to exploit oxide p p p pand transitional ore remains an option when Paramo is clearly defined

Investment Case

In spite of current permitting difficulties, a significant opportunity exists to develop a robust underground project at Angostura

The advantages of an underground project compared to the open pit options are:

Reduced environmental footprint

Lower capital cost

M il fi dMore easily financed

Shorter lead time to production

Access to higher grade material

Significant blue sky potential in terms of expansion of current resources and new target areas

A healthy resource remains in place with potential to increase through further drillingA healthy resource remains in place with potential to increase through further drilling and exploration program. To date only 10% of 30,050 hectares have been explored

A good address: the company is operating in a highly prospective region

Upside ExplorationMongora Drill Program to Date

Defined by a large, 500 metre by 300 metre gold-in-soil anomaly.

The Company started 57 drill holes on the Mongora target, accumulating 19 459 metres to December 201019,459 metres to December 2010.

Similar to the Angostura deposit, the Mongora prospect hosts higher grade gold mineralization including 116 grams of gold per tonne over 2.0

22 2 f ld 2 0 d 12 3metres, 22.2 grams of gold per tonne over 2.0 metres and 12.35 grams of gold per tonne over 1.6 metres within broader zones of lower grade gold mineralization.

The mineralization contained in the oxidized and transitional rock at the Mongora area could be very important for the Angostura Project

Upside ExplorationLa Plata Drill Program to Date

5 kilometres southwest from Angostura. Elevation of up to 2,500 m.a.s.l.

Mineralization of gold, silver, copper, lead and zinc, a part of the mineralizing system parallel to La Baja creek; also hosts mineralization of g y p j ;Angostura and La Mascota

Occurs in sheeted faulted veins striking to northeast and east-west, steeply dipping to north and southdipping to north and south

System of fracturing controls the distribution of the alteration and mineralization

7,273 metres of core drilling have been completed since 2010. Future drilling program will be focused in defining the mineralization extension
