Jason Gigliotti, President of Sienna Resources stated, 'We are very fortunate to be able to work with such a well-respected, European focused capital markets group. EuroSwiss has built a large following of institution and high net worth investors throughout Europe and Sienna management is looking forward to working with EuroSwiss and having access to their multi-faceted targeted services. Sienna is very active on multiple projects at this time, with a primary focus in Ontario, Finland and Norway. Therefore it is logical for Sienna to partner with a European based firm and we now also have a significant percent of our shareholders being based in Europe. Sienna is expecting a strong flow of news from all of our projects in the coming weeks and management is very optimistic about what will be uncovered by having boots on the ground currently in multiple continents.'

The agreement with EuroSwiss is for an initial six months period, subject to renewal at the mutual agreement of both parties. Under the agreement, Sienna will pay EuroSwiss a fee of CAD 20,000 for the initial term of the agreement.

The agreement is subject to approval by the TSX Venture Exchange.
