Final Environmental Assessment Application Accepted by Canadian Environmental Assessment Agency for Formal Review ======================================================================= Vancouver, British Columbia: Avanti Mining Inc.

(TSX-V: AVT) (OTC: AVNMF.PK) ("Avanti" or the "Company") is pleased to announce that the Final Environmental Assessment (EA) Application / Environmental Impact Statement (EIS) for the Kitsault Mine Project ("Project") in northern British Columbia (BC) has been accepted by the Canadian Environmental Assessment Agency (CEA Agency) for formal review.

In a letter dated May 2, 2012 from the CEA Agency the formal review began on April 26, 2012 with a focused screening that indicated the application contained sufficient information to begin the review effective immediately.

To date, the BC EAO and the CEA Agency have worked jointly to advance the Project through their respective environmental review processes.

In accordance with this joint review, a 30-day public comment period will begin on May 11, 2012.

The Final EA Application / EIS is posted on the BC EAOs Project Information Center website at www.eao.gov.bc.ca.

"The acceptance of Kitsault EA by the CEA Agency for formal review brings the federal and provincial environmental authorities together on the Projects review process," Mr.

Craig J.

Nelsen, President and CEO, stated.

"Avanti looks forward to the final review and receiving its Environmental Certificates for this mine development.

Both CEA Agency and BC EAO have committed to a harmonized review process that is commencing with the joint 30-day public comment period on the application." In anticipation of the successful outcome of the EA process, Avanti is working with the BC Ministry of Forests, Lands and Natural Resource Operations (MFLNO) to advance permit applications necessary for construction and operation of the Project.

The MFLNO works as a central government body responsible for coordinating BC and Canada permitting agencies under the provinces "1 Project -- 1 Process" policy.

This "synchronous" EA and permitting process is a relatively new government initiative aimed at streamlining the regulatory process.
Avanti Mining Inc.

is focused on the development of the past producing Kitsault Mine Project located north of Prince Rupert in British Columbia.

In late 2010, Avanti completed the Kitsault Feasibility Study on the Kitsault Mine Project, dated December 15, 2010, prepared by AMEC Americas Limited that showed Proven and Probable Reserves of 232.5 million tonnes averaging 0.081% molybdenum.
