======================================================================= News Release - Thursday, December 22, 2011 Avanti Submits Kitsault Mine Project Environmental Assessment Application For Screening Review ======================================================================= Vancouver, British Columbia: Avanti Mining Inc.

(TSX-V: AVT) (OTC: AVNMF.PK) ("Avanti" or the "Company") is pleased to announce that it has submitted its Environmental Assessment ("EA") Application for the Kitsault Mine Project in northern BC for the required 30-day review. This over 7,000+ page document will be reviewed for its compliance with our Application Information Requirements ("AIR") by the British Columbia Environmental Assesment Office, the Canadian Environmental Assessment Agency and members of the Kitsault EA Working Group.

The 30-day Screening Review period ends January 22, 2012, however Avanti has requested and BC EAO is considering a 15 day extension to this period because of the holiday season. "Submittal of the Kitsault Mine Project EA for initial screening review is a significant milestone within the Environmental Assessment process," Mr.

Craig J.

Nelsen, President and CEO stated.

"Avanti and its consultants have been collecting and analyzing new environmental and economic baseline information, as well as over twenty years of previous operators environmental and reclamation information to inform this application.

After this initial screening review is completed and if the Application is accepted, the formal 180-day review will commence." The purpose of the screening process is for EAO and CEA Agency to determine whether the Application contains sufficient information, as required by the Kitsault Mine AIR, for the working group, EAO and CEA Agency to undertake a comprehensive review of the Application.

This screening stage evaluation process does not involve an in-depth analysis of potential effects, as would occur during the Application review period, nor does it constitute a superficial scan of the Application.

Rather, the evaluation process involves conducting a detailed enough assessment of the Application to determine whether the Application meets the requirements of the AIR to the extent that potential effects of the proposed Project can be adequately assessed. 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.
