Further to the MacDonald Mines Exploration Ltd. (TSX VENTURE:BMK) ("MacDonald"
or the "Company") press release dated June 29, 2012, the Company is pleased to
announce it has now signed a definitive purchase and sale agreement for the
acquisition of all of Noble Mineral Exploration Inc's (TSX VENTURE:NOB),
("Noble") property interests in the James Bay Lowlands, Ring of Fire region.


In order to acquire those interests, which include a minority interest in 6
claims on otherwise 100% owned MacDonald property, the Company has agreed to the
following payments:




  a)  Cash: $150,000, of which $75,000 will be paid within 5 days           
      (refundable in the event the property is not transferred by the       
      deadline noted in the agreement) and $75,000 to be paid within 120    
      days of the transfer of the property,                                 
  b)  Common Shares: 3,000,000 common shares of the Company, and            
  c)  Warrants: the issuance of a total of 3,000,000 warrants to acquire    
      common shares of the Company with 1,000,000 warrants exercisable at a 
      price of $0.30 per share; 1,000,000 warrants exercisable at a price of
      $0.50 per share and 1,000,000 warrants exercisable at a price of $0.70
      per share. All warrants expire after two years from the date of       
      issuance.                                                             



This transaction has been approved by the TSX Venture Exchange ("TSX-V"). All
securities to be issued are subject to a hold period of four months and one day
from the date of issuance. 


The Company has received TSX-V approval for the recent acquisition of certain
Temex Resources Corp. (TSX VENTURE:TME) ("Temex") property interests in the Ring
of Fire as announced in the Company's July 5, 2012 press release.


In addition to acquiring Noble's 100% owned property in the region, this now
gives the Company a 100% interest in several claim blocks in which it previously
held a joint venture interest with Noble and/or Temex.


MacDonald's continues to drill VMS (copper/zinc) and nickel targets on its
highly prospective Butler property. Assays are pending.
