Forward-Looking Statements

Certain statements contained in this press release may constitute forward-looking statements under

Canadian securities legislation which are not historical facts and are made pursuant to the "safe

harbour" provisions under the United States Private Securities Litigation Reform Act of 1995.

Generally, forward-looking information can be identified by the use of forward-looking terminology

such as "expects" or "it is expected", or variations of such words and phrases or statements that

certain actions, events or results "will" occur. Forward-looking statements in this press release include

the scope and success of the planned exploration program at the Castelo de Sonhos project and the

Company's opinion that it has clear title to the Castelo de Sonhos property. Such forward-looking

statements are based upon the Company's reasonable expectations and business plan at the date

hereof, which are subject to change depending on economic, political and competitive circumstances

and contingencies. Readers are cautioned that such forward-looking statements involve known and

unknown risks, uncertainties and other factors that may cause a change in such assumptions and the

actual outcomes and estimates to be materially different from those estimated or anticipated future

results, achievements or position expressed or implied by those forward-looking statements. Risks,

uncertainties and other factors that could cause the Company's plans to change include changes in

demand for and price of gold and other commodities (such as fuel and electricity) and currencies;

changes or disruptions in the securities markets; legislative, political or economic developments in

Brazil; the need to obtain permits and comply with laws and regulations and other regulatory

requirements; the possibility that actual results of work may differ from projections/expectations or

may not realize the perceived potential of the Company's projects; risks of accidents, equipment

breakdowns and labour disputes or other unanticipated difficulties or interruptions; the possibility of

cost overruns or unanticipated expenses in development programs; operating or technical difficulties

in connection with exploration, mining or development activities; the speculative nature of gold

exploration and development, including the risks of diminishing quantities of grades of reserves and

resources; and the risks involved in the exploration, development and mining business. Although

management of the Company has attempted to identify important factors that could cause actual

results to differ materially from those contained in forward-looking statements or forward-looking

information, there may be other factors that cause results not to be as anticipated, estimated or

intended. The Company disclaims any intention or obligation to update or revise any forward-looking

statements whether as a result of new information, future events or otherwise, except as required by

applicable securities laws.
