Caution: Mineral resources that are not mineral reserves do not have demonstrated economic viability.

In accordance with NI 43-101, the technical report was completed by internal technical staff with assistance from external experts associated with the project and under the direction of senior technical staff including Joe Ringwald, Vice President of Mining, Jason Dunning, Vice President of Exploration and Rick MacInnis, ScoZinc's General Manager. All are Qualified Persons as defined by NI 43-101.

The restart of the ScoZinc Mine is an important near term strategic objective in advancing Selwyn to becoming a producer. The completion of project financing and the achieving of production at ScoZinc will facilitate Selwyn's longer term objective of advancing the very large Selwyn Project to production. Selwyn Project is located in the Yukon, and is being advanced by Selwyn Chihong Mining Ltd., a company jointly owned by Selwyn and its joint venture partner Yunnan Chihong Canada Ltd. The known deposits at Selwyn Project have the potential for large-scale production, and to provide a secure supply of zinc and lead to meet the future needs of markets in Asia and beyond.

This news release has been reviewed and approved by Joseph Ringwald, P.Eng., Vice President of Mining with Selwyn Resources Ltd., a Qualified Person under NI 43-101.

Cautionary Note

The PEA is preliminary in nature and includes inferred mineral resources that are considered too geologically speculative to be subject to economic considerations that would enable them to be categorized as mineral reserves. There is no certainty that the forecast results stated in the PEA will be realized. For a full description of known risks that could materially affect potential development of the ScoZinc zinc-lead project, see Selwyn's Annual Information Form dated March 28, 2012 under the heading "Risk Factors" which are incorporated by reference herein and are available on www.sedar.com under the Selwyn Resources profile. In addition, Selwyn needs to raise approximately $31.5 million to fund the restart of the ScoZinc Mine.

Forward-looking information is based on management's reasonable assumptions, estimates, expectations, analyses and opinions on the date of this news release. These are based on management's experience and perception of trends, current conditions and expected developments, and other factors that management believes are relevant and reasonable in the circumstances, but which may prove to be incorrect.

These factors include, but are not necessarily limited to, results of the restart program at the ScoZinc Mine, exploration and development activities, the interpretation of drilling results and other geological data, the uncertainties of resource and reserve estimations, receipt of permits to conduct mining activities, project cost overruns or unanticipated costs and expenses, the availability of funds, fluctuations in metal prices, currency fluctuations, and general market and industry conditions. There is no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such information.
