intend, and does not assume any obligation, to update this forward-looking information. Forward-looking information includes, but is not

limited to, statements with respect to planned exploration programs and estimates of the costs thereof, anticipated rates of recovery,

timing and amount of future production, anticipated capital cost , currency exchange rates, future price of gold and the effects thereof,

estimation of measured and indicated resources, realization of mineral resource estimates and the economic viability thereof, timing and

amount of estimated capital expenditures, project infrastructure and layout, estimated project time-line, requirements for additional capital

and alternatives for project development.

The forward-looking information contained in this presentation is based on certain assumptions that Eco Oro believes are reasonable,

including, that the current price of and demand for gold will be sustained or will improve, the supply of gold will remain stable, Eco Oro’s

development plans can be achieved, the general business and economic conditions will not change in a material adverse manner,

financing will be available if and when needed on reasonable terms and Eco Oro will not experience any material accident, labour

dispute, or failure of plant or equipment.

However, forward-looking information involves known and unknown risks, uncertainties and other factors which may cause the actual

results, performance or achievements of Eco Oro to be materially different from any future results, performance or achievements

expressed or implied by the forward-looking information. Such factors include, among others, risks relating to Eco Oro’s ability to obtain

adequate financing for the development of the Angostura Project, conclusions of economic evaluations, changes in project parameters as

plans continue to be refined, future prices of gold, mineral resources are not as estimated, unexpected variations in grade or recovery

rates, risks related to fluctuations in the currency market, risks relating to title disputes, risks relating to all Eco Oro’s properties being

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 a 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.

qualified persons, as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects. The estimates of Eco Oro’s

mineral resources are subject to the qualifications and assumptions set out therein and readers are cautioned that mineral resources

which are not mineral reserves do not have demonstrated economic viability The technical information in this presentation is derived

TSX: EOM

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 impact on environment, no intervention in

Páramo, reduced water consumption, reduced impact on

water table and reduced risk of water contamination.

Much reduced plant and infrastructure and hence much

reduced capital investment.

Reduction in land acquisition.

Reduction in explosives, reagents and chemicals

consumption.

Reduction in movement of personnel and supplies to and

from mine site, thereby reducing transport risk.

TSX: EOM

Characteristics of UG project

Targets high grade oxides, transitional ores and sulfides.

Potential for waste and tailings placement (backfill) in mine

workings.

Smaller waste dump and tailings dam footprint on surface.

Smaller plant and infrastructure footprint on surface.

Because of smaller volumes, potential for overhead cable

transport of ores to plant and remote plant location.

Potential for local grinding and transport of pulp in pipeline to

remote treatment plant location.

Potential to increase mineable resources (high grade targets

outside of stope boundaries, mineralization open at depth and

to south, incremental cost approach for lower grade resources).

The underground project may neutralize prospect of ever

returning to an open pit project because the high grade

resources will be exhausted making an open pit uneconomic.

Total gold and silver production is less and the rate of

production lower than would be the case in an open pit project.

Nonetheless, the underground project would remain a large

scale operation.

Strategies to reconfigure project

Engage government and local authorities on project

reconfiguration and definition of Páramo.

Implement Sustainable Social Responsibility (SSR)

strategy.

Aggressively pursue drilling programme to increase

underground resources and improve classification.

Complete feasibility study 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 Móngora, La Plata and Armenia.

Provide flexibility in project configuration for consolidation

of mineral resource assets owned by others in the 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

Access to higher grade material

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

(Armenia, Mongora, La Plata).

A healthy resource remains in place with potential to increase through further drilling and exploration

programmes. 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$80.9 million cash; no debt (June, 2011).
