They estimate their Utah site contains 3 million-plus tons of iron oxide hydroxide in the form of limonite, goethite and hematite, grading 95 percent on average.
Studies of remote sensing images and aeromagnetic data, together with the historical sampling results (see Figure 1 and Appendix 1 link below), have outlined several areas of potential haematite and/or goethite enrichment, providing attractive targets for initial exploration.

Analyzing this scale using the X-ray diffraction (XRD) technique showed that the main components of the scale was iron oxide; magnetite (Fe304) and Goethite; FeO(OH).
Indeed, the iron oxides that form as corrosion on rebar embedded in concrete have been found to be largely magnetite (FeO.[Fe.sub.2][O.sub.3]) interpenetrated by maghemite ([gamma]-[Fe.sub.2][O.sub.3]) along with some hematite [[([alpha]-[Fe.sub.2][O.sub.3]), possibly goethite ([alpha]-FeOOH), and other compounds [3, 17-21].

The authors of the new laboratory study found that low pH levels in seawater created a positive charge on samples of goethite (an iron oxide that is one of the most abundant compounds in ocean sediments), which then attracted negatively charged arsenic.
Alteration encountered in the hole includes: decalcification, calcite-filled solution cavities, remobilized carbon vein fillings and commonly intense oxidation to hematite and goethite.
