In addition, hematite ore only goes through one stage of screening and crushing, while magnetite has an additional round of processing. Magnetite. With the chemical formula Fe3O4, magnetite ore has much lower iron content than hematite ore.
A quartz–barite– limonite vein up to 3 m wide crops out near the hilltop. An inclined drill hole in the 1990s intersected only minor copper and gold mineralization. The boulders and pyrite precursor of the limonite suggest a hypogene advanced argillic or high sulfidation epithermal system.
