Golden Star Reports Increases in Power Costs in Ghana

Golden Star Resources Ltd. (TSX: GSC)(AMEX: GSS)(GSE: GSR) today announced that the cost of power from the national grid in Ghana will be increased as a result of higher world oil prices.

A decision of the Public Utilities Regulatory Committee (PURC) has been made public announcing an increase of power rates to high voltage customers, particularly mining companies and steel mills. While the details are still being negotiated, we expect the power rate increase to be effective July 1, 2008, with rates rising to a range of $0.20 to $0.24 per kilowatt-hour (kWh) compared to the present rate of $0.10 per kWh. For Golden Star this new power rate would translate into an increase of $60 to $85 per ounce based on forecasted production.

The cost of producing power within the country has increased due to growing consumption and higher oil prices on the world market. Approximately 60% of power is generated by hydro-electric power and 40% by thermal power. It is estimated that the blended cost of power generation in Ghana is currently $0.14 per kWh with oil prices at $140 per barrel. The Ghana Chamber of Mines is joining Golden Star and other affected mining companies in conducting negotiations with the relevant governmental agencies regarding the size of this increase in power rates.

Tom Mair, President and CEO of Golden Star stated that, "We are disappointed that the PURC appears to have specifically targeted the mining industry to carry the burden of the increased power generation costs. We intend to continue our discussions with the Government of Ghana regarding the increase and its impact on our operations and future investment plans while we review our options regarding production levels and spending plans."
