Mineral leases and material permits shall be issued in accordance with the classifications described below. No mineral leases will be issued in conflict with this classification.
1. Mineral Classification. (a) Metalliferous Minerals: shall include aluminum, antimony, arsenic, beryllium, bismuth, chromium, cadmium, cesium, columbium, cobalt, copper, fluorspar, gallium, gold, germanium, hafnium, iron, indium, lead, mercury, manganese, molybdenum, nickel, platinum, group metals, radium, silver, selenium, scandium, rare earth metals, rhenium, tantalum, tin, thorium, titanium, tungsten, thallium, tellurium, vanadium, uranium, ytterbium, zinc, and zirconium.(b) Potash: shall include the chlorides, sulfates, carbonates, borates, silicates, and nitrates of potassium.(c) Phosphate: shall mean any phosphate rock containing one or more phosphate minerals such as calcium phosphate and shall include all phosphatized limestones, sandstones, shales, and igneous rock.(d) Clay Minerals: shall mean a fine grained, natural, earthy material composed primarily of hydrous aluminum silicates, plastic-like when wetted, rigid when dried en-masse, and vitrified when fired to a sufficiently high temperature, which shall include kaolin, bentonite, ball clay, fire clay, fuller earth, and clays and clay minerals or shales having unique characteristics giving the mineral deposit distinct and special value, such as carbonaceous shale, humic shale, and baked shale, where the primary value or use is other than building, construction or landscaping.(e) Humic shale: shall refer to a dark colored shaley material containing humic acids or small particles of carbon, original organic tissue or other carbonaceous matter derived from plants and distributed throughout the whole mass. This classification does not include oil shale, bituminous-asphaltic sands, or coal.(f) Limestone: shall include sedimentary rock having a predominant composition chiefly composed of calcium carbonate or calcium magnesium carbonate where the primary value or use is other than building, construction, or landscaping.(g) Gemstone and Fossil: shall include precious, semi-precious or collectable mineral, and petrified material or stone having intrinsic value derived from its attractiveness or uncommon characteristics. This designation includes agate, amber, beryl, calcite, chert, coral, corundum, diamond, feldspar, garnet, geodes, jade, jasper, olivine, opal, pearl, quartz, septarian nodules, spinel, spodumene, topaz, tourmaline, turquoise, and zircon; and coquina, petrified wood, trilobites, and other common fossilized flora and invertebrate fauna.(h) Gypsum: a natural hydrated calcium sulfate that includes alabaster, anhydrite, gypsite, satin spar, and selenite(i) Gilsonite: a solid asphaultum found in place, in a vein, a lode, or rock.(j) Volcanic Material: includes volcanic pyroclastic material such as ash, blocks, bombs, and tuff; glassy volcanic glass material including obsidian, perlite, pitchstone, pumice, scoria, and vitrophyre; and other uncommon volcanic materials where the primary value or use is other than building, construction, or landscaping.(k) Industrial Sands: includes uncommon, naturally occurring sands having properties or containing minerals having special use in industrial processes or applications as determined by the director. This designation includes abrasive sands, filler sands, foundry sands, frac sands, glass sands, lime sands, magnetic sands, and silica sands.(l) Mineral Salts: shall include all naturally occurring salts.2. Material Classification. (a) Material permits may be issued for common varieties of clay or stone having a primary value or use in building, construction, or landscaping, including basalt, common clay, conglomerate, flagstone, gabbro, granite, lava aggregate, limestone, marble, onyx, quartzite, rhyolite, rip-rap, sandstone, serpentine, shale, slate, soapstone, trapstone, travertine, whether crushed, sized, dimensioned, or unprocessed, and when the director deems it consistent with agency plans and trust responsibilities.(b) No material permits will be issued in conflict with the Mineral Lease Classification under R850-25-100(1).3. Non-Classified Minerals or Materials. Mineral leases or material permits may also be issued for minerals or materials not listed under Subsections R850-25-100(1) and (2) at the discretion of the director. Alternatively, the director may issue a mineral lease or material permit for a non-classified mineral or material that is closely associated with a classified mineral or material so long as the mineral or material is specified as a leased or permitted substance in the mineral lease or material permit.
4. Close Association Minerals or Materials. A mineral lease or material permit may include other minerals or materials found in close association with the expressly leased mineral or permitted material, when the substance cannot reasonably be mined separately or mined and separated.
5. Multiple Classified Minerals. Mineral leases may also be issued to include a combination of classified minerals.
