TORONTO, ONTARIO--(Marketwire - July 23, 2012) - 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,

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.
