CENTRAL MICHIGAN AEROMAGNETIC SURVEY/ANALYSIS

Flown by Airmag Surveys, Inc.

Processing by EDCON-PRJ, Inc.

EDCON-PRJ has reprocessed and interpreted a non-exclusive, high sensitivity aeromagnetic survey in the central Michigan Basin. This survey is designed to map basement structures and lineaments that have affected emplacement of significant hydrocarbon reserves.
