CSC Citizen Stash Cannabis Corp

Columbus Silver Corporation (TSX VENTURE: CSC) ("Columbus Silver") is pleased to announce the signing of a non-binding Memorandum of Understanding (the "MOU") with Santa Fe Gold Corporation, to complete a business combination (the "Merger") by way of a court approved plan of arrangement.

Pursuant to the MOU, Santa Fe would acquire all of the outstanding common shares of Columbus Silver in exchange for Santa Fe common shares at an agreed exchange ratio of 1 Santa Fe share for every 5.82515 Columbus Silver shares (the "Exchange Ratio"). This represents an approximate 100% premium to Columbus Silver shareholders based on Columbus Silver's 20-day average closing share price as at September 22nd, 2010, the last day prior to CSC halting its stock pending this announcement.

The Merger effectively transitions Columbus Silver from an early stage explorer to a producing gold and silver company with production from Santa Fe's Summit Mine located in New Mexico. Any ore developed at Columbus Silver's Mogollon Project can be processed at Santa Fe's nearby mill in Lordsburg, New Mexico. Columbus Silver shareholders will therefore derive value from planned production growth and the potential of rising commodity prices, while participating in the upside offered from a broad portfolio of gold and silver exploration properties.

Under the MOU announced today:

--  Columbus Silver shareholders will receive 0.17167 Santa Fe common shares
    per Columbus Silver common share which implies a price per Santa Fe
    common share of US$1.13, using the September 22nd exchange rate of
    C$1.00 = US$0.97.

--  The number of shares that Columbus Silver warrant and option holders are
    entitled to receive upon exercise will be adjusted proportionately to
    reflect the Exchange Ratio. The original expiry terms will be
    maintained.

--  In connection with the Merger, Columbus Silver's majority shareholder
    Columbus Gold Corporation ("Columbus Gold") would convert outstanding
    debt owed by Columbus Silver totalling C$1,402,428.04 plus accrued
    interest to date of C$192,581.85 into 15,564,935 common shares of
    Columbus Silver calculated at a price of $0.10 per share on the
    principal amount and at $0.125 per share on the accrued interest (the
    "Debt Conversion").

--  In connection with the Merger, Columbus Gold and Santa Fe would complete
    a bridge financing to Columbus Silver in the form of a non-brokered
    private placement of 3,000,000 shares at a price of C$0.10 per share,
    for total gross proceeds of C$300,000 (the "Placement"). It is proposed
    that Santa Fe will subscribe to $100,000 and that Columbus Gold will
    subscribe to $200,000. The proceeds of the Placement will be used for
    working capital requirements and to pay for the legal fees and other
    transaction costs associated with the Merger. The Placement is not
    conditional upon the completion of the Merger. The Placement is subject
    to stock exchange and other regulatory approvals.

--  Following completion of the Merger and the other transactions
    contemplated herein, it is estimated that Santa Fe will be owned 91.37%
    by current Santa Fe shareholders and 8.63% by current Columbus Silver
    shareholders.

--  Following completion of the Merger and other transactions contemplated
    herein, it is estimated that Columbus Gold will own 3,808,474 common
    shares of Santa Fe, representing 3.74% of Santa Fe. Columbus Gold has
    agreed to subject all but 789,679 of those shares to a 180-day lock-up
    agreement.

--  On a fully diluted basis, it is estimated that Santa Fe will be owned
    90.5% by current Santa Fe shareholders and 9.5% by current Columbus
    Silver shareholders.

--  The Merger values Columbus Silver at approx. C$10,237,733 based on
    shares issued and outstanding after giving effect to the Debt Conversion
    and Placement.

--  On completion of the merger, it is anticipated that Columbus Silver's
    President & CEO, Robert Giustra, will be appointed to the board of
    directors of Santa Fe.

--  The Merger will be completed by way of a court-approved plan of
    arrangement whereby Columbus Silver will amalgamate with a newly formed
    wholly-owned subsidiary of Santa Fe and will voluntarily delist its
    common shares from the TSX Venture Exchange.

--  The Merger is subject to the final approval of the boards of directors
    of both companies and is conditional on stock exchange, regulatory
    approvals and court approvals. The Merger is also subject to Columbus
    Silver shareholder approval to be voted at a special meeting to be
    called to approve the Merger. Full details of the Merger will be
    included in the Management Information Circular to be filed with the
    regulatory authorities and mailed to Columbus Silver shareholders in
    accordance with applicable securities laws. The Merger is also subject
    to a 45-day due diligence period.

Robert F. Giustra, President and CEO of Columbus Silver, commented, "This is a very positive development for the shareholders of Columbus Silver and of Santa Fe. The successful completion of this Merger will position the combined company to deliver both near and long-term value to its shareholders through existing production growth as well as significant development and exploration upside from a diverse portfolio of precious metal properties."

Santa Fe's President and CEO, Pierce Carson, said, "This transaction is strategically important to Santa Fe and will significantly increase our controlled gold and silver resources available for processing at our fully-permitted and operating flotation mill near Lordsburg, New Mexico. Furthermore, Columbus Silver's portfolio of high quality US silver-gold properties provides excellent upside exploration potential. Two of these properties already have historic drilled resources aggregating over 500,000 ounces of gold equivalent ounces. The combination with Columbus Silver is a notable step forward in Santa Fe's objective to become a significant North American precious metals producer."

About Columbus Silver

Columbus Silver is a silver exploration and development company operating in the Western United States which controls a 100% interest (subject to royalties) in 7 silver properties in Utah, Arizona, New Mexico and Nevada. Columbus Silver's principal asset is its Mogollon silver-gold project in Catron County, New Mexico. Mogollon covers an extensive, silver-gold bearing epithermal vein field with reported historic production during the period 1905 to 1942 totalling 15,700,000 ounces silver and 327,000 ounces gold from approximately 1.7 million tons (1.5 million tonnes) of ore. Drilling at Mogollon in the 1980's was successful in outlining a partially delineated silver-gold deposit at the Consolidated Mine containing an historical resource of approximately 845,000 tons (767,000 tonnes) averaging 9.35 opt (320 g/t) silver and 0.15 opt (5.1 g/t) gold. A proposed drilling program was recently permitted at Mogollon. There are dozens of potentially mineralized veins at Mogollon with a combined strike length of more than 45 miles (72 km) that have never been drill tested, providing potential for considerable resource expansion.
