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).
