ITEM 1.01 ENTRY INTO A DEFINITIVE MATERIAL AGREEMENT

REVISED   ACQUISITION   AGREEMENT  FOR  BIG  BEAR  CLAIMS  WITH  MONTANA  MINING

On July  7,  2011,  the  Company  entered  into an  addendum  to the  previously
disclosed  letter  agreement  ("LOI")  dated Jun 15, 2011,  with Montana  Mining
Corporation, a Delaware corporation headquartered in Blaine, WA, to acquire 100%
of the Big Bear Mining Claims 1-9 located in the San Bernardino County (the "Big
Bear  Claims").  Under the  revised  terms of the LOI,  the  Company  will issue
11,000,000  restricted  shares of the Company (the  "Shares") to acquire 100% of
the Big Bear Claims.

The amended  terms allow the Company to  commence a limited  work  program  (the
"Work Program") to be completed within 120 days, at an estimated cost of $50,000
to $100,000.  If the Company is satisfied  with the results of the Work Program,
the Company shall issue  3,000,000  shares of its common stock within 30 days of
receiving the results and report of the Work Program.

The Company shall issue up to an additional 8,000,000 shares of its common stock
pursuant to the following  schedule for a total potential issuance of 11,000,000
shares as follows:

1.   Issue a  further  2,500,000  shares  upon 1  Million  oz of gold  proven by
     accepted geological methods

2.   Issue a  further  2,500,000  shares  upon 2  Million  oz of gold  proven by
     accepted geological methods

3.   Issue a further  1,500,000  shares  upon 2.5  Million oz of gold  proven by
     accepted geological methods

4.   Issue a  further  1,500,000  shares  upon 3  Million  oz of gold  proven by
     accepted geological methods

Drilling and other methods to prove up the gold  reserves  will commence  within
180 days of completion of the Work Program, subject to all required governmental
approvals.  Classification  of gold reserves as proven will be done according to
the standards  required by Canadian National  Instrument 43-101 or similar US or
Australian rules for such classification.
