Diamond Drill Mobilized to Evaluate High Priority Ni-Cu-PGE Targets Near Noront Discovery

TORONTO, ONTARIO: MacDonald Mines Exploration Ltd. (TSX Venture Exchange:BMK) ("MacDonald") and its partner Temex Resources Corp. (TSX Venture Exchange:TME, Frankfurt:TQ1) ("Temex" or "the Company") announce they have mobilized a diamond drill to begin testing several high priority geophysical targets on properties in the area of, and immediately adjacent to, the Noront Double Eagle Ni-Cu-PGE Discovery in the Webequie area of northern Ontario.

The first of several targets to be evaluated in this initial phase of diamond drilling is a well defined magnetic and electromagnetic feature that is known to extend for a minimum length of 400 metres based on the ground survey data gathered to date. Over the 400 metre interval the target body is very conductive and has a positive magnetic correlation on all lines surveyed to date.

Ground and airborne geophysical surveys are continuing and other targets have been outlined, some of which will be diamond drill tested this month. It is currently anticipated that a total of 3 to 4 targets will be drill tested this month with additional drilling set to continue in early 2008. The exact location of the additional proposed drill sites will be refined as additional geophysical data is gathered and interpreted over the ensuing weeks.

Virtually nothing is known of the geology close to the initial target due to the complete overburden cover in the area, however geophysical interpretation of the available regional data suggests the area is likely underlain by rocks similar to those that host the Noront Double Eagle Ni-Cu-PGE approximately 5 km to the west. It is also possible that the area may host rocks similar to those hosting the McFauld's area copper-zinc mineralization some 15 km to the northeast.

Chairman Bruce Durham commented, "We are excited to be drill testing some of these high priority targets on the joint venture property so quickly. We began acquiring land close to the Noront discovery immediately after Noront's announcement of their very significant nickel-copper discovery and have been focusing our efforts at moving the project along as quickly as possible. We understand that there may be as many as twelve drills operating for various companies in the area so it will be a busy winter for everyone."

Temex and MacDonald are equal partners on several properties in the vicinity of Noront's Double Eagle Ni-Cu-PGE discovery. Shortly after acquiring the properties the companies established the framework for the completion of certain work on the property prior to year end. That plan included airborne and ground follow-up geophysical surveying and initial diamond drilling of at least some of the resultant targets. MacDonald, the Operator expects drilling operations to commence in the next few days. The properties subject to the agreement total 1479 claim units and cover more than 60,000 acres.
