The Phosphoria Formation contains two ore zones.

It exists in a variety of forms and is prevalent in numerous environments including hydrothermal ore zones, modern lake and ocean sediments, and sedimentary rocks [1 6].

The separation, identification and assessment of high-grade ore zones from low-grade ones are extremely important in mining of metalliferous deposits.

Typical thickness of the upper and lower ore zone is 6 14 m, with 23 55 m of phosphatic shales (middle waste shale) separating the two ore zones.[1, 2].

Crone Geophysics offers a full suite of EM sensors for both borehole and surface surveys, which are very useful in mine development and production applications, specifically for defining the boundaries and sizes of conductive ore zones (Crone Geophysics 2017).

The radioactive minerals identified in the ore zone are pitchblende, coffinite and U Ti complex.

Ilgren (2004) summarized these results stating that "Only very rarely have non-asbestiform 'non-friable' amphibole (so-called cleavage fragment) minerals been found in the New Idria serpentine body but away from the ore zone".
