The document discusses the Toroparu Gold-Copper Project located in Western Guyana. It highlights that the project has over 4 million ounces of gold equivalent in measured and indicated resources as well as over 5 million ounces in inferred resources. A preliminary economic assessment indicated the project could have a net present value of $854 million. The company has $39 million in cash and a market capitalization of $335 million. It also notes that the company has established mining and exploration infrastructure in Guyana from over a decade of operating history in the country.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources: This annual information
form uses the terms “Measured”, “Indicated” and “Inferred” Resources. United States investors are advised that while such terms are
recognized and required by Canadian regulations, the United States Securities and Exchange Commission does not recognize them.
“Inferred Mineral Resources” have a great amount of uncertainty as to their existence, and 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 rules,
estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. United States investors are
cautioned not to assume that all or any part of Measured or Indicated Mineral Resources will ever be converted into Mineral Reserves.
United States investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists, or is economically or
legally mineable.

3 The preliminary economic assessment (the results of which were announced in March 22, 2011 press release) is preliminary in nature and includes inferred mineral resources that are considered too
speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary assessment will
be realized.

Notes and Disclaimer
Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by
environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues and are subject to the findings of a full feasibility study. The quantity and
grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated
or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category. The mineral
resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Reserves, Definitions and Guidelines
prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council December 11, 2005.
