Toronto, Ontario, Canada, September 21, 2007-Sulliden Exploration Inc. (“Sulliden” or the“Company”) (TSX: SUE) reports that the Injunction previously granted to Sulliden by the 55th Civil Court of Lima has been cancelled by a new judge of that Court following an application by Algamarca. Sulliden has appealed against the cancellation decision.

Following the Arbitration Award issued in Sulliden’s favor in July 2006, Sulliden obtained an injunction from the 55th Civil Court protecting the Arbitration Decision and ordering Algamarca and all parties dealing with Algamarca to comply with the Decision rendered by the Arbitration Tribunal in the dispute concerning Shahuindo property (See Sulliden Press Release August 1, 2006).

Following the recent decision of the Commercial Chamber of the Superior Court of Lima which declared null and void the Arbitration Decision and Award of July 2006, Sulliden appealed to the Supreme Court of Peru against the decision of the Commercial Chamber (See Sulliden Press Release August 29, 2007). The effect of the appeal is to suspend the resolution of the Superior Court and, pending the hearing of that appeal, the resolution is of no legal force or effect.

However, notwithstanding Sulliden’s appeal to the Supreme Court against the decision of the Superior Court, Algamarca made an application to the 55th Civil Court of Lima to have the Injunction previously granted to Sulliden in August 2006 and subsequent modifications thereto cancelled. Algamarca’s application was granted by the 55th Civil Court of Lima.

As the effect of Sulliden’s appeal of the Supreme Court is to suspend the resolution of the Superior Court nullifying the Arbitration Award, Sulliden has been advised that the decision of the 55th Civil Court of Lima to cancel the Injunction is improper and Sulliden has therefore appealed against that decision.

Sulliden had anticipated some such application and anticipates that further court actions or motions may be initiated by Algamarca in its efforts to have the registration of the Shahuindo concessions in Sulliden’s name revoked and other legal procedures in the ongoing legal dispute with regard to Sulliden’s Shahuindo Property.

Caution regarding forward-looking information:

Statements contained in this document which are not historical facts are forward-looking statements that involve risk, uncertainties and other factors that could cause actual results to differ materially from those expressed or implied by such forward-looking statements. This forward-looking information includes, or may be based upon, estimates, forecasts, and statements as to management’s expectations with respect to, among other things, the outcome of legal proceedings, the issue of permits, the size and quality of the company’s mineral resources, progress in development of mineral properties, future production and sales volumes, capital and mine production costs, demand and market outlook for metals, future metal prices and treatment and refining charges, and the financial results of the company. Factors that could cause such differences, without limiting the generality of the following, include: volatility and sensitivity to market metal prices impact of change in foreign currency exchange rates and interest rates; imprecision in reserves estimates; environmental risks including increased regulatory burdens; unexpected geological conditions; adverse mining conditions; political risks arising from operating in developing countries; legal title to properties, outcome of litigation, changes in government regulations and policies, including laws and policies; and failure to obtain necessary permits and approvals from government authorities; and other development and operating risks.

Mineral resources that are not mineral reserves do not have demonstrated economic viability. Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that mineral resources will be converted into mineral reserves.

Although the Company believes that the assumptions inherent in the forward-looking statements are reasonable, undue reliance should not be placed on these statements, which only apply as of the date of this document. The Company disclaims any intention or obligation to update or revised any forward-looking statement, whether as a result of new information, future events or otherwise.
