MacDonald Mines (TSX VENTURE:BMK)

TORONTO, ONTARIO--(CCNMatthews - May 1, 2006) - Macdonald Mines Exploration Ltd (TSX VENTURE:BMK) is pleased to announce the completion of the 2006 winter drill program on its McNugget property west of the McFauld's Lake area, Ontario. Eleven holes were drilled, totaling 2390m, in 5 areas that had ground geophysics completed on cut grids in February. The grids were cut over sections of extensive airborne VTEM anomalies extending for 13 kilometers of strike length.

Most drill holes intersected extensive chlorite and sericite alteration which contained significant sulphide mineralization, and locally extreme silica flooding and quartz vein breccias. Of the 11 holes drilled, 10 hit sulphide mineralization, and 9 intersected massive to near massive sulphides. One hole was drilled on a large circular magnetic anomaly and intersected gabbro and ultramafic intrusives with no significant mineralization. Five holes were spread along a strongly anomalous 4.6 km trend, and all hit massive and disseminated sulphides with visible copper and zinc mineralization. Logging and sampling continue, and will be completed within the next week.

MacDonald Mines recently completed drill program confirmed that the VTEM anomalies occur along a stratigraphic package containing felsic to intermediate fragmental volcanics. This package is bracketed to the north by strongly sheared and silica flooded mafic to ultramafic volcanics and intrusives; and sheared and altered intrusive porphyries to the south.

Assay results are pending and have been sent to Accurassay Labs in Thunder Bay for analysis.

The Company staged the McNugget exploration program out of the First Nations Community of Webequie. The community continues to provide excellent logistics support, which facilitates a very efficient exploration program.

Second Phase Drill Program To Commence In June

The company is planning a second phase drill program to commence June 15th 2006. This program is intended to follow up on the success of the recently completed first phase of the 2006 exploration program.

The drill program is being conducted under the supervision of GeoVector Management Inc., and Joe Campbell (P. Geo.) is the qualified person for all technical information contained in this release.
