Meteorites have never produced a commercially viable mineable deposit of Platinum Group Metals (PGMs) anywhere on Earth. While meteorites, particularly iron-nickel types, do contain PGMs like iridium, osmium, and platinum, their concentrations are generally not sufficient to justify large-scale mining operations. Additionally, the rarity and scattered nature of meteorite deposits make them impractical for mining purposes.

No known company mines and crushes meteorites specifically for their PGM content as a commercial endeavor. Instead, meteorites are primarily collected for scientific study, private collections, and occasionally as jewelry or novelty items. The costs associated with recovering and processing meteorites are far higher than traditional terrestrial sources of PGMs, making it an economically unfeasible endeavor.

The PGMs that are sold commercially are primarily sourced from terrestrial mining operations, such as those found in South Africa, Russia, and Canada, where they occur in mineable concentrations in ores like norite and chromitite associated with igneous and volcanic activity.

Below are some examples of PGM compositions of well known meteorite samples organized by their type. These PGM concentrations are very low compared to what would be needed for economically viable mining, let alone the absurd ounces per ton SDRC is alluding to have been confirmed in their unreleased assays.

An Iron Meteorite: (e.g., "Canyon Diablo")

The famous Canyon Diablo meteorite, associated with the Meteor Crater in Arizona, has been analyzed for its metal content, revealing the presence of PGMs:

Platinum (Pt): 15-25 parts per million (ppm)
Iridium (Ir): 3-10 ppm
Ruthenium (Ru): 5-8 ppm
Osmium (Os): 2-5 ppm
Rhodium (Rh): Trace amounts
Palladium (Pd): 10-20 ppm


a Stony-Iron Meteorite: (e.g., Esquel Pallasite)

Pallasites are a type of stony-iron meteorite containing olivine crystals embedded in an iron-nickel matrix, which sometimes includes PGMs. For example, the Esquel Pallasite, a well-known specimen, has been found to contain:

Platinum (Pt): 20-30 ppm
Iridium (Ir): 5-15 ppm
Ruthenium (Ru): 5-10 ppm
Osmium (Os): 3-7 ppm
Palladium (Pd): 15-25 ppm


a Chondrite (e.g., Allende)

Some carbonaceous chondrites, like the Allende meteorite that fell in Mexico, also contain PGMs, though generally in much lower concentrations than iron meteorites.

Platinum (Pt): 0.2-1 ppm
Iridium (Ir): 0.05-0.5 ppm
Ruthenium (Ru): Trace amounts
Osmium (Os): Trace amounts
Palladium (Pd): Trace amounts


Achondrites (e.g., HED Meteorites)

HED (Howardite, Eucrite, and Diogenite) meteorites, believed to originate from the asteroid Vesta, also contain small amounts of PGMs.

Platinum (Pt): 0.1-0.5 ppm
Iridium (Ir): 0.05-0.2 ppm
Ruthenium (Ru): Trace amounts
Osmium (Os): Trace amounts
Palladium (Pd): Trace amounts


Lunar Meteorites

Lunar meteorites are fragments of the Moon that were ejected by impacts and later landed on Earth. These meteorites have very low concentrations of PGMs.

Platinum (Pt): <0.1 ppm
Iridium (Ir): Trace amounts, usually <0.01 ppm
Ruthenium (Ru): Negligible amounts
Osmium (Os): Negligible amounts
