Result of a helicopter geophysical survey in the Meråker area have been inter- preted with the goal of locating mineralization. A comparison of geophysical data over known mines and showings has determined that mineralization is correlated with 70 ppm or greater EM anomalies in the high frequency channel. Associated magnetic anomalies are either weak (under 25 nT) or non-exists. Results indicate that two zones are favourable for mineralization. One is along the contact between Sulåmogruppen greenstones and meta-sandstones and the second is along an axis connecting Dudu gruve with Langsund gruve and extending north to Hammerskallen skjerp.
