Such factors include, among others: gold price volatility; impact of any hedging activities, including margin limits and margin calls; discrepancies between actual and estimated production, between actual and estimated reserves and resources and between actual and estimated metallurgical recoveries; costs of production, capital expenditures, costs and timing of construction and the development of new deposits, success of exploration activities and permitting time lines; changes in national and local government legislation, taxation, controls, regulations and political or economic developments in any of the countries in which either corporation does or may carry out business in the future; risks of sovereign investment; the speculative nature of gold exploration, development and mining, including the risks of obtaining necessary licenses and permits; dilution; competition; loss of key employees; additional funding requirements; and defective title to mineral claims or property.  In addition, there are risks and hazards associated with the business of gold 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 the factors described or referred to in the section entitled “Risk Factors” in Northgate’s Annual Information Form for the year ended December 31, 2006 or under the heading “Risks and Uncertainties” in Northgate’s 2006 annual report, both of which are available on SEDAR at www.sedar.com, and which should be reviewed in conjunction with this document.
