MacDonald Mines Exploration Ltd. announces that it has contracted Abitibi Géophysique Inc. to conduct a gravity survey on land-based targets on the Hornby mineral claims, jointly owned by Temex Resources and MacDonald Mines, and on the Company’s 100% owned BigMac Property.

These claims are interpreted to host the potential for a chromite horizon(s). The Hornby Property is immediately south of KWG/Spider’s “Big Daddy” chromite discovery.   Based on the airborne data, Dr. Larry Hulbert, P. Geo, along with Hadyn Butler, P. Geo, have interpreted a number of potential chromite horizons on the BigMac property.  The gravity sections will cross these horizons at five locations varying from 2 to 10 kilometres apart.

The gravity survey will help define drill-ready targets along the interpreted horizons. The gravity survey is expected to be completed by mid-March, 2010.  The gravity technique has proven capable of defining chromite intercepts in the Ring of Fire and have been successfully utilized by both Freewest (Cliffs) and Spider/KWG in their discoveries.

MacDonald will also refocus exploration attention on its McNuggett Property.  Previous drilling results have been the catalyst for the complete re-interpretation of all exploration activity.  Quentin Yarie, P. Geo., MacDonald Mines’ new Vice President of Exploration heads this new initiative and he is being assisted by both consulting geologists Hadyn Bulter, P. Geo, and Dr. Larry Hulbert, P.Geo.  This analysis has outlined previous drill hole areas where the drilling did not fully explain the anomalous electromagnetic conductors.  The revised interpretation has outlined targets that will be drilled in the upcoming exploration program, which is planned to commence in March, 2010.

Abitibi Geophysics is using SCINTREX CG5 AutoGrav for a gravity survey.
