Pursuant to the Offering, Erdene sold 25,926,844 units of the Company (the "Units") at a price of $0.27 per Unit. Each Unit consists of one common share and one-half (½) of one common share purchase warrant (the "Warrant"). Warrants are exercisable by the holder into one common share of the Company within two years of the closing date, at a price of $0.40 per share. Erdene will pay finder's fees of $127,699 and will issue 97,031 finder's warrants in connection with the Offering. The finder's warrants are exercisable on the same terms as the unit Warrants.

Proceeds of the Private Placement will be used to fund exploration, early development works for the Company's Bayan Khundii Gold Project, and for general working capital purposes.

Mr. Sprott through 2176423 Ontario Ltd., a corporation which is beneficially owned by him acquired 12,530,955 Units pursuant to the private placement for aggregated consideration of $3,383,357.85. As a result of the Acquisition, Mr. Sprott beneficially owns and controls 61,225,488 Shares and 9,598,827 Warrants representing approximately 17.8% of the issued and outstanding Shares of the Company on a non-diluted basis and approximately 20.0% of the issued and outstanding Shares of the Company on a partially diluted basis assuming exercise of such warrants.

The Shares were acquired by Mr. Sprott for investment purposes. Mr. Sprott has a long-term view of the investment and may acquire additional securities including on the open market or through private acquisitions or sell the securities including on the open market or through private dispositions in the future depending on market conditions, reformulation of plans and/or other relevant factors.
