Additional Cautionary Notes & Statements

CAUTIONARY NOTE TO U.S. READERS CONCERNING ESTIMATES OF MEASURED AND INDICATED RESOURCES.

Information concerning the properties and operations of Eco Oro has been prepared in accordance with Canadian standards under applicable Canadian securities laws, and may not be comparable to similar information for United States companies. The terms “mineral resource”, “measured mineral resource” and “indicated mineral resource” used in this presentation are Canadian mining terms as defined in accordance with NI 43-101 under guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Standards on Mineral Resources and Mineral Reserves adopted by the CIM Council on December 11, 2005. While the terms “mineral resource”, “measured mineral resource” and “indicated mineral resource” are recognized and required by Canadian regulations, they are not defined terms under standards of the United States Securities and Exchange Commission. Under United States standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve calculation is made. As such, certain information contained in this presentation concerning descriptions of mineralization and resources under Canadian standards is not comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of the Unites States Securities and Exchange Commission. Readers are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into mineral reserves.

Motivation for UG project

No requirement for Angostura & Paez leach pads.

No requirement for large open pit.

No requirement for large waste dump at Móngora.

No plant infrastructure in Páramo.

Much reduced rock movement (<2% of open pit).

Much reduced surface footprint, no intervention in protected areas, reduced water consumption, reduced risk of water contamination.

Much reduced plant and infrastructure and hence much reduced capital investment.

Reduction in land acquisition.

Reduction in movement of personnel and supplies to and from mine site, thereby reducing transport risk.

All of the above will enhance project viability and help expedite permitting process.

TSX: EOM

Characteristics of UG project

Targets high grade oxides, transitional ores and sulfides.

VAT or Agitated Leach process for oxides and transitional ores reducing residence time, improving recoveries and reducing risk of water contamination.

Much reduced volumes of oxide and transitional ores making neutralization of leach residues more viable and reducing risk of water contamination.

Opportunity to target higher grade resources earlier in production schedule and improve ROI.

Opportunity to use aerial ropeway transport of mineral to remote plant location.

Opportunity for remote location of tailings impoundment and reducing footprint by backfilling mine workings.

Potential for local grinding and transport of pulp in pipeline to remote plant location.

Potential to increase mineable resources (mineralization open at depth in Angostura deposit, satellite deposits at Armenia, La Plata, La Violetal & Móngora, incremental cost approach for lower grade resources).

Strategies to advance project

Engage government and local authorities on project reconfiguration and definition of Páramo.

Implement Sustainable Social Responsibility (SSR) strategy.

Aggressively pursue infill drilling program to increase underground resources and improve classification.

Complete feasibility studies for UG project. Develop human and capital capacity in the area of

operations for construction and operating phases of project.

Maintain investors and analysts properly and timeously informed of project progress.

Provide flexibility in project configuration for consolidation of mineral resource assets including the satellite deposits of Armenia, La Plata, La Violetal and Móngora.

Provide flexibility in project configuration for potential regional consolidation of mining in area of operations.

TSX: EOM

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 include:

Reduced environmental footprint

Lower capital cost

More easily financed

Shorter lead time to production

Earlier access to higher grade material

Significant upside in Angostura deposit - open at depth.

Significant blue sky potential in terms of expansion of current resources and new target areas (Armenia, La Plata, La Violetal, Móngora).

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

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

Strong balance sheet US$68.8 million cash; no debt (30 September 2011).
