Avanti Mining announces alternative site for Tailings Management Facility for
Kitsault Project

TSX-V:AVT

VANCOUVER, June 1 /CNW/ - Avanti Mining Inc. ("Avanti") is pleased to announce that it has identified an alternative location for a Tailings Management Facility ("TMF") for its Kitsault molybdenum project (the "Kitsault Project"). Comparative scoping level engineering studies suggest that initial capital costs may be reduced by approximately CDN$50 million to CDN$70 million from the CDN$228 million estimated on comparable components in the Preliminary Feasibility Study ("PFS"). Avanti is currently advancing its Feasibility Study. It has been studying alternative TMF sites since the PFS was published in November 2009, under the direction of Knight Piesold. The study involved the selection of a more optimum TMF site after evaluating initial capital cost, operating cost, construction schedule and environmental considerations. Several alternative TMF sites have emerged from this study, with a site located approximately two kilometers east of the mine ultimately being selected. This alternative TMF site will become the focus of the Feasibility Study and the British Columbia Environmental Assessment Act review of the Kitsault Project.

Avanti is focused on the development of the past producing Kitsault molybdenum mine located north of Prince Rupert in British Columbia. Kitsault has Proven and Probable reserves of 215 million tonnes grading 0.085% Mo and containing 368 million pounds of recoverable molybdenum as outlined in the Technical Report dated December 15, 2009 which is available on the Company's website as well as at www.sedar.com. Ken Brouwer, P. Eng., of Knight Piesold, a Qualified Person as defined in NI 43-101, has reviewed and approved the scientific or technical information in this press release.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
