Following completion of the Initial Purchase, Avalon has the right, in its sole discretion, to sell up to an additional US$27,200,000 worth of Shares to LPC, from time to time and on such terms and conditions as are described in the Purchase Agreement. The purchase price for any additional sales of Shares will be based on prevailing market prices of the Shares immediately preceding any notice of sale without any fixed discount. Under the terms of the Purchase Agreement, Avalon has control over the timing and amount of any future sale of Shares subject to certain conditions, and LPC is obligated to make such purchases, if and when the Company presents LPC with a valid purchase notice. There are no upper price limitations, negative covenants or restrictions on Avalon's future financing activities. Avalon may terminate the Purchase Agreement at any time, at its sole discretion, without any cost or penalty. The Company will issue 918,521 Shares to LPC as a commitment fee for entering into the Purchase Agreement, and will issue up to an additional 918,521 Shares as compensation on a pro rata basis as the US$30,000,000 purchase amount is funded. LPC has also agreed not to cause or engage in any manner whatsoever, any direct or indirect short selling or hedging of the Shares.

Don Bubar, President and CEO said, "We are pleased to have an experienced resource investor like LPC demonstrate confidence in the future of the Nechalacho Project by becoming a shareholder in our Company at this time." Mr. Bubar continued, "We see this agreement with LPC as a timely complement to our existing ATM program, providing the Company with more certainty and additional flexibility in how we access financing for our ongoing project development activities."

The Company has filed a prospectus supplement, dated November 27, 2013, with respect to its U.S. registration statement on Form F-10 (the "Registration Statement") and Canadian final base shelf prospectus (the "Base Shelf Prospectus"), each dated September 10, 2013, pursuant to which the Company may issue up to US$8,500,000 of Shares pursuant to the terms of the Purchase Agreement (representing an aggregate market value of not more than 10% of the market value of the Company's outstanding Common Shares based on the determination date under applicable securities laws). Pursuant to the Purchase Agreement, the Company may file additional prospectus supplements in the United States and in Canada in the future to qualify the sale of additional Shares to LPC that would result in aggregate gross proceeds to the Company of up to US$30,000,000. No offers or sales of any Shares will be made in Canada pursuant to the Purchase Agreement or the prospectus supplement.

The Company plans to use the net proceeds from the Financing for working capital and other general corporate purposes, including funding ongoing operations and/or capital requirements, discretionary capital programs and potential future acquisitions.

The Financing has been approved by NYSE MKT. The Toronto Stock Exchange has accepted notice of the Financing and the Company is relying on the section 602(g) exemption under the Toronto Stock Exchange Company Manual.
