    • High-Resolution Aeromagnetic Survey of Mountain Pass, California

    Metadata Updated: January 20, 2026

    A detailed aeromagnetic survey of Mountain Pass, California was flown by CGG Canada Services Ltd. (CGG) during November and December, 2016. The high-resolution helicopter survey was flown at a flightline spacing of 100 and 200 m, a flightline azimuthal direction of 70 degrees, a nominal flightline elevation above ground of 70 m, and consists of about 1,814 line-kilometers. Tie lines were spaced at a 1-km interval with a flight-line azimuthal direction of 160 degrees. A Scintrex CS-3 cesium magnetometer was used throughout the airborne survey as well as for the ground base station survey. Data are presented as residual magnetic intensity (RMI) in nanoteslas (nT).
