Crosshair Commences Drilling at its Bootheel Uranium Project in Wyoming and Opens Denver Office

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 6, 2011) - Crosshair Exploration & Mining Corp. (TSX:CXX)(NYSE Amex:CXZ) is pleased to announce that drilling has commenced at the Bootheel Property located within the Shirley Basin in southern Wyoming. The 2011 program will consist of 30,000 feet (9,144 metres) of drilling as well as metallurgical and hydrological test work in conjunction with continued permitting. The goal of the program is to upgrade the existing inferred resource to the indicated category as well as capture more of the historic resource. An updated National Instrument (NI) 43-101 Mineral Resource estimate is expected in Q4 2011, to be followed by a scoping study in early 2012.

Crosshair is also pleased to announce that it has opened its USA office in Denver, Colorado. Mark Ludwig, Crosshair's COO and Bevo Beaven, Crosshair's Vice President Corporate Communications are both based in the new Denver office, which is in the downtown business district at Suite 400, 1400 16^th Street, Denver, CO 80202.

"The Denver office will provide an excellent, centrally located platform to support our growth as we continue to advance both our Bootheel and Juniper Ridge projects in Wyoming and look at new opportunities in the western US," says Stewart Wallis, President and CEO of Crosshair.

The initial independent NI 43-101 Mineral Resource estimate on the Bootheel Property includes an indicated resource of 1.09 million pounds of uranium oxide (1.44 million tons at 0.038% eU3O8) and an additional inferred resource of 3.25 million pounds of uranium oxide (4.40 million tons at 0.037% eU3O8). The resource remains open for expansion with less than 60% of the historical resource area included in this initial estimate. Further details about this resource estimate can be found in the NI 43-101 Technical Report titled "Technical Report on the Bootheel Uranium Property, Shirley Basin Mining District, Albany County, Wyoming, U.S.A." dated September 8, 2009 and available on SEDAR at www.sedar.com.

Uranium mineralization is hosted by several individual sandstone beds at the Bootheel Property. The majority of the resources are hosted by the Sundance Formation, which demonstrated in the 2008 laboratory testing to have the potential to be recovered using in-situ recovery (ISR) techniques (please refer to News Release dated February 5, 2009). Information on the benefits of ISR and how it works can be found at: http://www.crosshairexploration.com/s/InSitu.asp.

The Bootheel Property, together with the Buck Point Property, cover 8,524 acres of gross mineral lands within the Shirley Basin in southern Wyoming and make up the Bootheel Project. Crosshair, through a wholly owned subsidiary, and Ur-Energy Inc. (TSX:URE)(NYSE Amex:URG), through a wholly owned subsidiary, are the members of The Bootheel Project, LLC, which holds title to the Bootheel Project. Crosshair has fully earned a 75% interest in the Bootheel Project.

Forward-looking statements or information relate to, among other things: the completion and expected timing of a resource estimate, completion of a scoping study, the details of the drill program, the exploration potential of the Company's properties and the production potential of Bootheel. By their nature, forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements, or other future events, to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Such factors include, among others, the following risks: the risks associated with outstanding litigation, if any; risks associated with project development; the need for additional financing; operational risks associated with mining and mineral processing; fluctuations in uranium, gold and other commodity prices; title matters; environmental liability claims and insurance; reliance on key personnel; the potential for conflicts of interest among certain officers, directors or promoters with certain other projects; the absence of dividends; competition; dilution; the volatility of our common share price and volume; tax consequences to U.S. shareholders and other risks and uncertainties, including those described in the Risk Factors section in the Company's Annual Report on Form 20-F for the financial year ended March 31, 2011 filed with the Canadian Securities Administrators and available at www.sedar.com.

Cautionary Note Concerning Reserve and Resource Estimates

This press release uses the terms "reserves", "resources", "proven reserves", "probable reserves", "measured resources", "indicated resources" and "inferred resources". United States investors are advised that, while such terms are recognized and required by Canadian securities laws, the United States Securities and Exchange Commission (the "SEC") does not recognize them. Under United States standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Mineral resources that are not mineral reserves do not have demonstrated economic viability. United States investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into reserves. Inferred Resources are in addition to Measured and Indicated Resources. Further, inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher category. Therefore, United States investors are also cautioned not to assume that all or any part of the inferred resources exist, or that they can be mined legally or economically. Disclosure of "contained ounces" is permitted disclosure under Canadian regulations, however, the SEC normally only permits issuers to report "resources" as in place tonnage and grade without reference to unit measures. Accordingly, information concerning descriptions of mineralization and resources contained in this release may not be comparable to information made public by United States companies subject to the reporting and disclosure requirements of the SEC. National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Unless otherwise indicated, all reserve and resource estimates referred to in this press release or released by the Company in the future have been or will be prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum Classification System. The requirements of NI 43-101 are not the same as those of the SEC and any reserves reported by the Company in compliance with NI 43-101 may not qualify as reserves under the SEC's standards.
