TORONTO, ONTARIO-- MacDonald Mines Exploration Ltd. (TSX VENTURE:BMK) announces today that the winter program carried out on its McNugget and LG3.5 property is now complete with all assay results received. The following is a summary of the winter exploration programs conducted as well as an outline for future programs.
WINTER 2007 PROGRAM SUMMARY
The extensive winter program conducted on the McNugget Property has been completed and all assay results have now been received. In total, about 35 kilometers of line cutting followed by magnetometer, HLEM and gravity surveys was conducted on the Salo, Pullen and Campbell grids.
The diamond drilling program was intended to target known mineralization and further define geophysical anomalies as well as drill testing of favorable responses defined by the current geophysical surveys. In addition to the base metal and gold targets on the McNugget Property, the Company also drilled some previously defined airborne magnetic anomalies believed to be potential kimberlite targets.
A total of seventeen holes (2,437 meters) of diamond drilling was completed and the summary of this work is presented below.
Five diamond drill holes, drilled east of the previously defined Campbell Zone intersected narrow massive sulphide horizons. Significant results are listed in Table 1 below. Two drill holes were put down to test magnetic "bulls-eye" anomalies believed to be caused by kimberlite, which was not intersected in either hole. Two drill holes were drilled into conductors on the Pullen Grid and assay results indicated no economic mineralization in these two holes. Finally, 8 diamond drill holes were drilled to test conductors on the Salo Grid located on the eastern part of the property. Nickel sulphide mineralization was intersected in two of the eight drill holes.
Drill hole MN-07-39 assayed 0.36% Ni over 4.5 meters and 0.26% Ni over 27.0 meters hosted by Gabbro (including 0.37% Ni over 6.0 meters and 0.40% Ni over 4.5 meters). In addition, drill hole MN-07-40 intersected 0.23% Cu and 0.17% Ni over 3 meters in Gabbro. Drill hole MN-07-40 is located 1.1 km west of MN-07-39 on what is interpreted to be a separate conductor array. Mineralization in both holes occurs as stringer sulphides. Drill hole MN-07-39 is the sole drill hole to sample the conductor that has been well defined by high resolution airborne TEM and extends over a distance of 1 km.

First Nations Community of Webequie
The Company once again operated its base camp out of the First Nations Community of Webequie, which is about a 15 minute helicopter ride from the McNugget Property. In co-operation with the Community, the Company has set-up a permanent core building and storage area located near the airport.
With the Community's assistance and support, this is now the fifth program we have conducted using Webequie as a base camp. We have looked to the Community to supply both infrastructure and personnel to support the exploration programs. As Community members continue to gain experience in exploration activity, it greatly enhances the efficiency and effectiveness of our programs. We would once again like to take this opportunity to thank Chief Scott Jacob and the Community for their continued support and assistance.
Helicopter support was provided by Expedition Helicopters, Cochrane, Ontario and the diamond drilling was completed by Cartwright Drilling, Goose Bay, Labrador. The line cutting as well as magnetometer and HLEM surveys were conducted by Exsics Exploration, Timmins, Ontario. The gravity survey was completed by Alan Spector, Toronto, Ontario and the gravity leveling was done by Total Exploration, Timmins, Ontario.
Assay results were provided by ALS Chemex, Vancouver, BC.
LG 3.5 PROPERTY
Exploration on MacDonald's LG 3.5 Property was completed during early March by Virginia Mines Inc. Due to severe weather conditions only three diamond drill holes were drilled during the program but they tested the "best" EM conductors. No significant economic mineralization was intersected during the program and Virginia Mines, in consultation with the Company, has made the decision that unless some compelling information/reason comes forward to reconsider, no further exploration will be carried out on the property.
FUTURE PROGRAMS - BASE METALS & NICKEL
With the ongoing search for Base Metals and the discovery of Nickel we now have 2 exploration opportunities. MacDonald's geologists, Hadyn Butler, P. Geo and Randall Salo, P. Geo are currently designing an exploration program to follow-up on the nickel sulphide intersections described above as well as further investigation of VMS, gold and kimberlite targets on the McNugget Property including the area surrounding MN-06-27 (0.92% Cu, 1.74% Zn, 0.04% Pb, 11.0 g/t Ag and 0.12 g/t Au over 6.36 meters; including 2.0 m of 1.76% Cu, 1.0% Zn (see news release Dec. 18, 2006). An exploration program is also being evaluated for the Big Mac Property to follow up on base metal, gold and diamond targets.
The prevalence of base metals demands further exploration and we are reminded of the number of significant deposits that were discovered through perserverance and dedicated exploration activity. The abundance of mineralization in the Sachigo Greenstone Belt has provided the foundation for our belief that finding an economical deposit is achievable and that this potential prize remains worthy of our efforts and expenditures.
PREVIOUS EXPLORATION PROGRAM HIGHLIGHTS
Highlights of the fall 2006 drill program on the Campbell Zone include holes MN06-20 with 3.59m assaying 0.16% Cu, 7.46% Zn and 31 g/t Ag; MN-06-21 with 8.05m assaying 0.91% Cu, 2.64% Zn and 17 g/t Ag, including 1.99m assaying 12.08% Zn, and 5.68m assaying 1.22% Cu; and MN-06-22 with 2.73m assaying 0.33% Cu, 6.95% Zn, 1.00 g/t Au and 23 g/t Ag, including 1.28m assaying 12.82% Zn. (Cu equals Copper; Zn equals Zinc; Ag equals Silver; Au equals Gold; g/t equals grams per ton)
Drilling on a north-south orientated horizon located on the west side of the McNugget Property had a best intersection in near massive sulphides in hole MN06-27 of 6.36m assaying 0.92% Cu, 1.74% Zn and 11 g/t Ag, including 2.00m assaying 1.76% Cu.
The Attawapiskat James Bay Lowlands Properties reside in the Thunder Bay and Porcupine Mining Division, Ontario, east of the First Nations Community of Webequie. The Company's properties consist of 2 major claims collectively referred to as the "B Mac" claims and the "M Nugget" claims respectively.
Claims on "B Mac" are contiguous and consist of 84 number claims, mostly as 16 unit blocks with some 12 unit blocks and irregular sizes for a total of 1,197 claim units or approximately 19,382 hectares.
Claims on "M Nugget" are contiguous and consist of 40 numbered claims, mostly as 16 unit blocks with two 8 unit blocks for a total of 624 claim units or approximately 10,096 hectares.
On May 4, 2007 the Company announced the granting of 2,625,000 stock options to directors, officers and consultants exercisable at $0.10 per share with an expiry date of May 4, 2011. The options were issued pursuant to a Stock Option Plan approved by shareholders at an Annual and Special meeting held on June 28, 2006.
POTENTIAL PROPERTY ACQUISITIONS & JOINT VENTURES
As part of a go forward strategy, the company will look to augment its James Bay Project with another exploration program. The company is currently engaged in that search and hope to make an announcement to that effect in the near future.
