These statements relate to future events or future performance and reflect Goldgroup's expectations regarding the future growth, results of operations, business prospects and opportunities of Goldgroup. These forward-looking statements reflect Goldgroup's current internal projections, expectations or beliefs and are based on information currently available to Goldgroup.

Certain assumptions have been made regarding the forecast 2010 production at Cerro Colorado of between 25,000 to 30,000 ounces of gold. Many of these assumptions are based on factors and events that are not within the control of Goldgroup and there is no assurance they will prove to be correct. Such factors include, without limitation: capital requirements, fluctuations in the international currency markets and in the rates of exchange of the currencies of Canada, the United States and Mexico; price volatility in the spot and forward markets for commodities; discrepancies between actual and estimated production, between actual and estimated reserves and resources and between actual and estimated metallurgical recoveries; changes in national and local governments in any country Goldgroup currently or may in the future carry on business; taxation; controls; regulations and political or economic developments in the countries in which Goldgroup does or may carry on business; the speculative nature of mineral exploration and development, including the risks of obtaining necessary licenses and permits, diminishing quantities or grades of reserves; competition; loss of key employees; additional funding requirements; actual results of current exploration or reclamation activities; changes in project parameters as plans continue to be refined; accidents; labour disputes; defective title to mineral claims or property or contests over claims to mineral properties. In addition, there are risks and hazards associated with the business of mineral exploration, development and mining, including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins, flooding and gold bullion losses (and the risk of inadequate insurance or inability to obtain insurance, to cover these risks) as well as "Risks and Uncertainties" included in the Annual Information Form and MD&A for Goldgroup available at www.sedar.com.
