Aterra Investments Acquires Additional Secured Convertible Debentures of GB Minerals Ltd.

TORONTO, March 19, 2014 /CNW/ - Aterra Investments Limited ("Aterra") announces that on March 18, 2014, pursuant to a private placement offering of up to $2,000,000 aggregate principal amount of secured convertible debentures of GB Minerals Ltd. ("GB Minerals") due March 31, 2015, it acquired $1,000,000 aggregate principal amount of such debentures (the "Purchased Debentures"). The Purchased Debentures are in addition to $2,100,000 aggregate principal amount of secured convertible debentures (the "Owned Debentures") previously issued to, or otherwise acquired by, Aterra.  Aterra and GB Minerals have also agreed to extend the maturity date of the Owned Debentures from March 31, 2014 to June 30, 2014.

The Purchased Debentures bear interest at 10% per annum. Every $1,000 principal amount of Purchased Debentures is convertible at any time, at the holder's option, into 5,000 common shares of GB Minerals ("Common Shares") at a price of $0.20 per share.  At the time of conversion of the Purchased Debentures, any and all accrued interest is also convertible at the holder's option into Common Shares at the same conversion price.

In addition to the Purchased Debentures and the Owned Debenture, Aterra also owns 26,067,450 Common Shares of GB Minerals (the "Owned Shares"), which represent approximately 39.2% of the currently outstanding Common Shares.  Assuming Aterra were to fully convert its Purchased Debentures and its Owned Debentures, but none of the interest thereon, and assuming no other new issuances of Common Shares by GB Minerals at or prior to such time, Aterra would acquire 15,500,000 Common Shares upon conversion of the Purchased Debentures and Owned Debentures representing in aggregate 18.9% of the then outstanding Common Shares after giving effect to such conversion. Of these, the 5,000,000 Common Shares issuable upon the exercise of the Purchased Debentures would represent 6.1% of the then outstanding Common Shares. Taking into account the Common Shares acquired upon such conversion, together with the Owned Shares, Aterra would beneficially own an aggregate of 41,567,450 Common Shares, representing approximately 50.7% of the then outstanding Common Shares.

Aterra acquired the Purchased Debentures for investment purposes and continues to monitor the business, prospects, financial condition and potential capital requirements of GB Minerals.  Depending on its evaluation of these and other factors, Aterra may from time to time in the future increase or decrease its ownership, control or direction over the common shares or other securities of GB Minerals through market transactions, private agreements, subscriptions from treasury or otherwise.
