 Inc. ("Aurum&amp;#x201D; or the &amp;#x201C;Company") is a Delaware
 corporation, originally incorporated in Florida as Liquid Financial
 Engines, Inc. The principal stockholder of Aurum is Golden Target
 Pty Ltd., an Australian corporation (&amp;#x201C;Golden&amp;#x201D;), which
 owned 96.21% of Aurum as of July 31, 2013.&lt;/font&gt;&lt;/div&gt;

 January 20, 2010, the Company re-incorporated in the state of
 Delaware (the &amp;#x201C;Reincorporation&amp;#x201D;) through a merger
 involving Liquid Financial Engines, Inc. (&amp;#x201C;Liquid&amp;#x201D;) and
 Aurum, Inc., a Delaware Corporation that was a wholly owned
 subsidiary of Liquid. The Reincorporation was effected by merging
 Liquid with Aurum, with Aurum being the surviving entity. For
 financial reporting purposes Aurum is deemed a successor to
 Liquid.&lt;/font&gt;&lt;/div&gt;

 August 2009, the Company decided to focus on mineral exploration
 for gold and copper in the Lao Peoples Democratic Republic (Lao
 P.D.R or Laos). The Company is considered to be in the exploration
 stage.&lt;/font&gt;&lt;/div&gt;

 December 2010, the Company executed a Management and Shareholders
 Agreement with Argonaut Overseas Investments Ltd
 (&amp;#x201C;AOI&amp;#x201D;), an indirectly wholly owned Subsidiary of
 Argonaut Resources N.L., in respect to Argonaut&amp;#x2019;s 70% held
 Century Concession in Laos.&lt;/font&gt;&lt;/div&gt;

 agreement appoints Aurum as the manager of the Century Thrust Joint
 Venture Agreement (&amp;#x201C;Joint Venture&amp;#x201D;) and gives the
 Company the right to earn 72.86% of AOI&amp;#x2019;s interest in the
 Joint Venture which is equivalent to a 51% beneficial interest in
 the Century Concession. In order to acquire this interest, Aurum
 may be required to spend US$6.5 million on exploration within the
 five year period ending December 10, 2015.&lt;/font&gt;&lt;/div&gt;

 February 10, 2011, the Company entered into a Deed of Agreement
 with the shareholders of the Lao Inter Mining Options Ltd
 (&amp;#x201C;LIMO&amp;#x201D;) which granted Aurum an option to purchase
 LIMO&amp;#x2019;s 20% interest in the Joint Venture. This Agreement, in
 conjunction with the Management and Shareholders Agreement with AOI
 would have enabled Aurum to acquire a 71% beneficial interest in
 the Century Concession. On October 24, 2011, the Company executed a
 Deed of Variation of Call Option extending the exercise date of
 Option to April 24, 2012, for a consideration of $55,000 for each
 month extended (see note 14). In April 2012, the Company decided
 not to exercise the option to purchase 20% of the Joint
 Venture.&lt;/font&gt;&lt;/div&gt;

 Company&amp;#x2019;s ability to continue operations through the
 remainder of 2013 is dependent upon future funding from affiliated
 entities, capital raisings, or its ability to commence revenue
 producing operations and positive cash flows.&lt;/font&gt;&lt;/div&gt;
