The chief ore mineral is pitchblende, which occurs with adularia and ankerite. Solid solution exists between dolomite, the iron-dominant ankerite and the manganese-dominant kutnohorite. Uncommon sources of lime include coral, sea shells, calcite and ankerite. It occurs associated with calcite, baryte, ankerite, siderite, benstonite, galena, sphalerite, pyrite, and quartz. There are also some other small unmined mineral veins, such as ankerite, molybdenite and haematite. Calcite, barite, ankerite, and pyrite cemented veins are found in immediate proximity of the fault. The veins are composed of siderite, quartz and ankerite, with siderite making up the gangue. It forms a series with dolomite, and with ankerite. Buffalo Ankerite is an old mining area and there are some homes. Alteration has produced analcime, ankerite, calcite, clay, hematite, iddingsite, pyrite, quartz, saponite, serpentine and zeolite. Ankerite occurs with siderite in metamorphosed ironstones and sedimentary banded iron formations.
