The stable form of cobalt is produced in supernovae through the r-process. It comprises 0.0029% of the Earth's crust. Free cobalt (the native metal) is not found on Earth because of the oxygen in the atmosphere and the chlorine in the ocean. Both are abundant enough in the upper layers of the Earth's crust to prevent native metal cobalt from forming.

The low concentration of nickel in the IIAB group leads to most of the meteoric iron becoming kamacite. All iron meteorites are made of a native metal called meteoric iron. The concentration of nickel has an influence on the mineralogy of the meteoric iron. During cooling kamacite is exsolved from taenite.

The Udachnaya Pipe in Russia produces samples of the native metal. This mine is a kimberlite pipe, rich in diamonds, and the reducing environment helped produce both elemental chromium and diamonds.Chromium from Udachnaya-Vostochnaya pipe, Daldyn, Daldyn-Alakit kimberlite field, Saha Republic (Sakha Republic; Yakutia), Eastern-Siberian Region, Russia, Mindat. The relation between Cr(III) and Cr(VI) strongly depends on pH and oxidative properties of the location.

Except as recently delivered in meteoric iron, pure cobalt in native metal form is unknown on Earth. The element has a medium abundance but natural compounds of cobalt are numerous and small amounts of cobalt compounds are found in most rocks, soils, plants, and animals. In nature, cobalt is frequently associated with nickel. Both are characteristic components of meteoric iron, though cobalt is much less abundant in iron meteorites than nickel.

Coloradoite, also known as mercury telluride (HgTe), is a rare telluride ore associated with metallic deposit (especially gold and silver). Gold usually occurs within tellurides, such as coloradoite, as a high-finess native metal. The quest for mining led to the discovery of telluride ores which were found to be associated with metals. Tellurides are ingrown into ores containing these precious metals and are also responsible for a significant amount of these metals being produced.

Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam). Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as color) embedded in rock minerals. Ores in which gold occurs in chemical composition with other elements are comparatively rare. They include calaverite, sylvanite, nagyagite, petzite and krennerite.

He was also heavily involved in developing the first plans for a native-controlled Native Metal Industries Ltd, which was still in operation in 1980. With his staff, Deiter helped organize the Indian Association of Alberta and the Manitoba Indian Brotherhood. Deiter was instrumental in the founding of the National Indian Brotherhood in Canada and was its first president, serving from 1968 to 1970. Deiter had a relatively conservative approach to issues around indigenous self-government, education and community development.

The term "Indigenous metal" has sometimes been used synonymously with "tribal metal" and "native metal", which is music influenced by indigenous heritage and explore themes of experienced dispossession, liberation and death as well as cultural and linguistic preservation. These artists add cultural music and imagery such as traditional instrumentation, indigenous traditional fashion and melodies. It is influenced by Viking metal bands' approach to cultural heritage. Percussion and traditional wind instruments are becoming a core compositional element in indigenous metal music.

Platinum can occur as a native metal, but it can also occur in various different minerals and alloys. That said, Sperrylite (platinum arsenide, PtAs2) ore is by far the most significant source of this metal. A naturally occurring platinum-iridium alloy, platiniridium, is found in the mineral cooperite (platinum sulfide, PtS). Platinum in a native state, often accompanied by small amounts of other platinum metals, is found in alluvial and placer deposits in Colombia, Ontario, the Ural Mountains, and in certain western American states.

It consists of the band's original song "Home" and a cover to The Mission - "Beyond The Pale". The reviews were very supportive and created big expectations for the band's forthcoming album.A review of 'Home' in metalstorm In January 2015, Subterranean Masquerade released their second album - The Great Bazaar with Kjetil Nordhus as the main vocalist and Paul Kuhr as harsh vocalist. The album is characterized with many different music styles, middle-eastern melodies and non-native metal instrument such as clarinet, flute, oud and trumpets.

Gold is the most well known of the native metals. Most gold is mined as native metal and can be found as nuggets, veins or wires of gold in a rock matrix, or fine grains of gold, mixed in with sediments or bound within rock. The iconic image of gold mining for many is gold panning, which is a method of separating flakes and nuggets of pure gold from river sediments due to their great density. Native gold is the predominant gold mineral on the earth.

The album's style, sound and aesthetic both inspired and highlighted Brazil's indigenous culture. Songs such as "Ratamahatta", "Itsári" and "Canyon Jam" feature contributions and collaboration with one of Brazil's indigenous peoples the Xavante. Many scholars view Roots as part of the global movement of metal music, and interest in local and regional cultures outside of traditional western music. True native metal (heavy metal featuring only Native American artist and use of traditional language and instruments) formed in the areas of Arizona,New Mexico and West Texas.

There is an increasing trend of using ICP-MS as a tool in speciation analysis, which normally involves a front end chromatograph separation and an elemental selective detector, such as AAS and ICP-MS. For example, ICP-MS may be combined with size exclusion chromatography and quantitative preparative native continuous polyacrylamide gel electrophoresis (QPNC-PAGE) for identifying and quantifying native metal cofactor containing proteins in biofluids. Also the phosphorylation status of proteins can be analyzed. In 2007, a new type of protein tagging reagents called metal-coded affinity tags (MeCAT) were introduced to label proteins quantitatively with metals, especially lanthanides.

The Mystick Krewe of Clearlight was founded in 1996 as an instrumental side-project by members of New Orleans bands Eyehategod, Down, and Crowbar. This project has allowed the members to explore music outside their native metal genre. After several years of shows in New Orleans with the occasional out-of-town show they recorded their self- titled debut album via Tee Pee Records in 2000. This was followed by The Father, the Son and the Holy Smoke, a 2001 split release with Acid King on Man's Ruin Records, featuring Scott "Wino" Weinrich (the Obsessed, Saint Vitus, Spirit Caravan, the Hidden Hand) on vocals.

One place where metallic cadmium can be found is the Vilyuy River basin in Siberia. Although mercury is an extremely rare element in the Earth's crust, because it does not blend geochemically with those elements that constitute the majority of the crustal mass, mercury ores can be highly concentrated considering the element's abundance in ordinary rock. The richest mercury ores contain up to 2.5% mercury by mass, and even the leanest concentrated deposits are at least 0.1% mercury (12,000 times average crustal abundance). It is found either as a native metal (rare) or in cinnabar (HgS), corderoite, livingstonite and other minerals, with cinnabar being the most common ore.

Mercury is an extremely rare element in Earth's crust, having an average crustal abundance by mass of only 0.08 parts per million (ppm). Because it does not blend geochemically with those elements that constitute the majority of the crustal mass, mercury ores can be extraordinarily concentrated considering the element's abundance in ordinary rock. The richest mercury ores contain up to 2.5% mercury by mass, and even the leanest concentrated deposits are at least 0.1% mercury (12,000 times average crustal abundance). It is found either as a native metal (rare) or in cinnabar, metacinnabar, corderoite, livingstonite and other minerals, with cinnabar (HgS) being the most common ore.

Patio Process at the Gould & Curry Mill, Comstock Lode, USA, 1866 Silver ores were crushed (typically either in "arrastras" or stamp mills) to a fine slime which was mixed with salt, water, magistral (essentially an impure form of copper sulfate), and mercury, and spread in a 1-to-2-foot-thick (0.30 to 0.61 m) layer in a patio (a shallow-walled, open enclosure). Horses were driven around on the patio to further mix the ingredients. After weeks of mixing and soaking in the sun, a complex reaction converted the silver to native metal, which formed an amalgam with the mercury. Heating this amalgam drove off the mercury, leaving the silver.

Many of the first metal artifacts that archaeologists have identified have been tools or weapons, as well as objects used as ornaments such as jewellery. These early metal objects were made of the softer metals; copper, gold, and lead in particular, as the metals either as native metal or by thermal extraction from minerals, and softened by minimal heat (Craddock, 1995). While technology did advance to the point of creating surprisingly pure copper, most ancient metals are in fact alloys, the most important being bronze, an alloy of copper and tin. As metallurgical technology developed (hammering, melting, smelting, roasting, cupellation, moulding, smithing, etc.), more metals were intentionally included in the metallurgical repertoire.

Nugget of native platinum (Kondyor mine, Khabarovsk Krai, Russia) A native metal is any metal that is found pure in its metallic form in nature. Metals that can be found as native deposits singly or in alloys include aluminium, antimony, arsenic, bismuth, cadmium, chromium, cobalt, indium, iron, manganese, molybdenum, nickel, niobium, rhenium, selenium, tantalum, tellurium, tin, titanium, tungsten, vanadium, and zinc, as well as the gold group (gold, copper, lead, aluminium, mercury, silver) and the platinum group (platinum, iridium, osmium, palladium, rhodium, ruthenium). Among the alloys found in native state have been brass, bronze, pewter, German silver, osmiridium, electrum, white gold, silver-mercury amalgam, and gold-mercury amalgam. Only gold, silver, copper and the platinum group occur native in large amounts.

Krasnojarsk meteorite A common error is to associate their name with the asteroid 2 Pallas but their actual name is after the German naturalist Peter Pallas (1741–1811), who studied in 1772 a specimen found earlier near Krasnoyarsk in the mountains of Siberia that had a mass of . The Krasnoyarsk mass described by Pallas in 1776 was one of the examples used by E.F.F. Chladni in the 1790s to demonstrate the reality of meteorite falls on the Earth, which were at his time considered by most scientists as fairytales. This rock mass was dissimilar to all rocks or ores found in this area (and the large piece could not have been accidentally transported to the find site), but its content of native metal was similar to other finds known from completely different areas.

Lead ions can replace the native metal ions in several key enzymes, such as zinc cations in the ALAD enzyme, which is also known as porphobilinogen synthase, and is important in the synthesis of heme, a key component of the oxygen-carrying molecule hemoglobin. This inhibition of heme synthesis appears to be the molecular basis of lead poisoning (also called "saturnism" or "plumbism"). Computational experiments reveal that although the coordination number does not change upon substitution in calcium- binding proteins, the introduction of lead distorts the way the ligands organize themselves to accommodate such an emerging lone pair: consequently, these proteins are perturbed. This lone-pair effect becomes dramatic for zinc- binding proteins, such as the above-mentioned porphobilinogen synthase, as the natural substrate cannot bind anymore - in those cases the protein is inhibited.
