VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jul 23, 2013) - Tintina Resources Inc. ("Tintina" or the "Company") (TSX VENTURE:TAU)(OTCQX:TINTF) is pleased to report that the Montana Department of Environmental Quality ("MT DEQ") has released the draft Environmental Assessment ("EA") of Tintina's proposed Exploration License Amendment (the "Amendment"), which includes construction of an exploration decline to access the high grade Johnny Lee copper deposit, located on the Company's 100% owned Black Butte Copper Project, Montana, USA. The EA constitutes preliminary approval of the Amendment, contingent on the Company's acceptance of several mitigating actions; and contingent on the MT DEQ's evaluation of comments stemming from a 45 day public comment period which will end August 26, 2013. During the comment period the MT DEQ will announce a date, place, and time for a public meeting in order to allow verbal and written comments by members of the public. Tintina recognizes that final approval of the Amendment will be based on analysis of all comments received on the EA.

Tintina has worked diligently with the MT DEQ during preparation of the application for the Amendment, which was first submitted in November of 2012, and has continued to revise the proposal to provide sufficient information for the MT DEQ to complete a comprehensive and accurate EA. Tintina is presently reviewing the EA, and looks forward to completion of the public comment period and final authorization from the MT DEQ to begin construction of the exploration decline. The Company is continuing to advance initiation of a feasibility study on the Black Butte Copper Project.
