"We are pleased to generate this additional income from the Pioche Project whilst increasing the option exercise price. This is a win-win arrangement. Tolsa has carried out a significant amount of exploration and has defined extensive and thick beds of sepiolite clay but needs more time to understand the commercial properties of the Pioche sepiolite and determine the best processing methods and range of commercial products that might be produced at Pioche. We believe that Tolsa, as the world's largest producer of sepiolite, is best placed to maximise the development potential of the project and the value of our ongoing royalty interest and so we are happy to give them the additional time required to achieve this."

Patrick Cheetham, Executive Chairman, Sunrise Resources plc

"We welcome the opportunity to continue our evaluation of the Pioche Deposit which we see as a potentially important development opportunity for Tolsa in the US. We look forward to working closely with Sunrise to bring about a positive result for all concerned."

Rafael González, Chief Mining Officer Tolsa S.A.

About Sepiolite

Sepiolite is a rare form of clay with very few commercial deposits in the world. It is non-swelling, lightweight and highly porous. It is used extensively in pet litter, agriculture as a slow-release absorbent and adsorbent carrier for chemicals and pesticides and in animal feeds as a binder and carrier for nutrients and growth promoter. It is also a valuable gelling agent and viscosity modifier in several industrial products.
