This presentation provides an overview of Greystar Resources and its Angostura gold/silver project in Colombia. Greystar is focused on exploring and developing the Angostura project, which has an initial underground resource estimate of 2.4 million ounces of gold and 13.4 million ounces of silver. The presentation discusses Greystar's strong financial position with no debt and $98 million in cash as of December 2010. It also notes that permitting applications for an open pit/heap leach project were suspended due to environmental concerns and the company is now evaluating an underground mining project and examining other development alternatives for the Angostura project.

3. 43-101 Disclosure Statement
TSX:GSL AIM:GSL
Information Concerning Estimates of Mineral Reserves and Resources and Exploration Results
The 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 the
terms. SEC.
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

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 physical
characteristics 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 of
the 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 and
reasonably 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.

TSX:GSL AIM:GSL
In it f
I spite of current permitting difficulties, a significant opportunity exists t d
t itti diffi lti i ifi t t it i t to develop a
l
robust underground project at Angostura
The advantages of an underground project compared to the open pit options are:
Reduced environmental footprint
Lower capital cost
More easily fi
M il financed
d
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 drilling
and exploration program. To date only 10% of 30,050 hectares have been explored

Mongora Drill Program to Date TSX:GSL AIM:GSL
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
19 459 metres to December 2010
2010.
Similar to the Angostura deposit, the Mongora prospect hosts higher
grade gold mineralization including 116 grams of gold per tonne over 2.0
metres, 22 2 grams of gold per tonne over 2 0 metres and 12 3 grams
22.2 f ld 2.0 d 12.35
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
