Although difficult financial market conditions persisted during the first 8 months of 2012, the Company was able to accomplish a number of goals set out at the onset of the year. On April 2, the Company received an updated resource estimate for the Elk Creek Niobium Deposit including the following highlights:

    0.67% Nb2O5;
--  An increase in inferred status tonnage and grade from the previous
    resource estimate (News Release dated April 28, 2011); from 80.1 Mt
    grading 0.62% Nb2O5 to 83.3 Mt grading 0.63% Nb2O5.

On July 19th, the Company announced the finalization of a joint venture agreement concerning the Company's Australian Properties which included the following highlights:

--  Quantum will retain a 20% carried to production interest in the project;
--  Quantum will be reimbursed for its previously incurred exploration funds
    (estimated at $100,000 Australian dollars) and will receive 3,750,000
    common shares of Victory Mines Limited upon successful completion of its
    Initial Public Offering ("IPO") on the Australian Stock Exchange
    ("ASE").

Victory has since informed the Company that all necessary documentation for their IPO has been filed with the ASE, whereby Victory is planning to raise $4,000,000 (Australian dollars) at an IPO price of $0.20 per common share, with an anticipated closing date and listing of its common shares in September, 2012.

In addition, the Company has signed Non-Disclosure and Confidentiality agreements with several parties concerning potential joint-venture and/or financing arrangements for development of the Elk Creek Niobium project. While discussions continue to advance, readers are cautioned that there is no assurance that these discussions will result in any transaction.

The Company has also reached an agreement through its wholly owned subsidiary, Silver Mountain Mines Corp. ("Silver Mountain"), Perry English for Rubicon Minerals Corporation ("English") concerning Silver Mountain's interest in 8 claim units located in the Kenora Mining Division, Ontario, Canada (the "Tait Property"), whereby the Company will issue 400,000 shares to English in lieu of a cash payment that was due pursuant to the underlying option agreement between Silver Mountain and English dated July 31, 2009, subject to TSX Venture Exchange approval. The Company entered into a subsequent option agreement dated November 28, 2011 with Titan Goldwork Resources Inc. whereby Titan can earn up to a 70% interest in the Tait property (see NR November 28, 2011 for complete details) which remains in effect.
