MacDonald Mines Plans September Drilling Program Based on the Results of the 2009 Summer Exploration Program On Its Nickel, PGM & Base Metal Property in the La Ronge District of Saskatchewan

TORONTO, ONTARIO--(Marketwire - Sept. 9, 2009) - MacDonald Mines Exploration Ltd. (TSX VENTURE:BMK) ("MacDonald" or the "Company") announces that extensive preliminary exploration activity has been completed on the Nielsen-Chisholm Property located NW of La Ronge, Saskatchewan. The program was designed to evaluate numerous high-strength EM conductors indicated by a helicopter-borne VTEM geophysical survey completed in 2008. The focus of the program was to qualify the EM conductors generated by the survey for drill testing. Evaluation of target areas was accomplished through: detailed geological mapping and prospecting; grab sampling of sulphide-bearing rocks; Beep Mat TM and VLF-EM geophysical surveys; and targeted organic soil geochemical sampling.

Numerous High-Priority Targets

Twenty-three high priority conductive anomalies were examined over the course of the summer field season. Many of the conductors were found to be associated with sub-cropping sulphide mineralisation enriched in Cu, Ni, Zn and Ag. The organic soil sampling has successfully allowed discrimination of the conductors by outlining a number of multi-element geochemical anomalies. A minority of the mineralized zones was previously explored in the 1960's but did not obtain the benefit of modern exploration techniques outlined in the release and most of the targets represent new occurrences.

The Company has employed the services of Dr. Larry Hulbert to interpret the soil geochemical and geophysical data. He is a well-known geologist with many years experience in magmatic Ni-Cu-platinoid exploration and was the Geological Survey of Canada commodity expert in this field for many years. Utilizing past practices, Dr. Hulbert has employed proprietary geochemical discrimination tools to interpret the Property soil geochemistry on targets he has identified through interpretation of new Company airborne data, and his own data.

Dr. Hulbert has identified eight highly attractive drill targets on the property. These targets are interpreted to have strong potential for Magmatic sulphide mineralisation (Ni-Cu-Platinum Group Elements) and Volcanogenic Massive Sulphide (VMS) mineralization. A program of diamond drilling will be initiated September 15 over a minimum of eight targets for a total of 2,000m of drilling.
The Company is very pleased with the summer's exploration results and is anxious to drill test targets that have been defined by a combination of geological, geophysical and geochemical methods.

Favourable Geological Setting

The La Ronge area is host to what is known as the "La Ronge Horseshoe", an area related to the La Ronge Greenstone Belt that is known to host a significant number of VMS, gold, and ultramafic hosted magmatic Ni-Cu-PGE deposits. Recent geological mapping completed by the Company has confirmed the presence of exhalative horizons in metavolcanic rocks thought to represent the extension of the "Anglo-Rouyn Horizon". This horizon hosts the former Anglo-Rouyn Cu-Au mine which closed in 1975 and the un-mined Elizabeth Lake Cu-Zn deposit, both of which are classified as VMS-type deposits. Both deposits are associated with laterally extensive exhalative horizons similar to those observed on the Nielsen-Chisholm Property.

About the Nielsen-Chisholm Property

The Nielsen-Chisholm Property is located in the La Ronge District of Saskatchewan, and covers an area of 201 km2.
