Critical Metals/Risk Lists

The following are different examples of the latest available list of critical metals from various sources as stated:

1. Source: criticalmetals.com (current list as of March 2013)

Aluminium Beryllium Cerium Copper Dysprosium Erbium
Europium Gadolinium Gallium Gold Holmium Indium
Iridium Lanthanum Lithium Lutetium Magnesium Manganese
Molybdenum Neodymium Niobium Osmium Palladium Platinum
Praseodymium Rhenium Rhodium Ruthenium Samarium Scandium
Silver Tantalum Terbium Thulium Titanium Tungsten
Vanadium Ytterbium Yttrium      


Note: The x 16 rare earth metals (promethium not referenced) contained in the criticalmetals.com list are indicated by italics.


2. Source: Kaiser list of critical metals (Critical Metals Report as presented at the Critical Metals Emergency Forum in Toronto, March 2011)

Antimony Bismuth Cerium Chromium Cobalt Dysprosium
Europium Gallium Germanium Indium Lanthanum Molybdenum
Neodymium Niobium Palladium Platinum Praseodymium Rhodium
Samarium Scandium Selenium Tantalum Tellurium Terbium
Tin Titanium Tungsten Vanadium Yttrium Zirconium


Note: In the above list only 10 of the total 17 rare earth metals are included, again indicated by italics.


3. British Geological Survey – Latest Risk List (September 2012)

First introduced in 2011, the BGS risk list gives an indication of the relative risk to supply of 41 elements or element groups based on their abundance, production and reserves, as well as the political risks in producing countries.

The 41 (from previous 2011 BSGS Risk List of 52) chemical elements/element groups on the latest BGS Risk list are as follows (in order of risk, 10 being very high risk, to 1 being very low risk):

Rare earth elements (9.5) Thorium (7.6) Nickel (6.2)
Tungsten (9.5) Indium (7.6) Rhenium (6.2)
Antimony (9.0) Gallium (7.6) Lead (6.2)
Bismuth (9.0) Arsenic (7.6) Diamond (6.2)
Molybdenum (8.6) Magnesium (7.1) Manganese (5.7)
Strontium (8.6) Tantalum (7.1) Gold (5.7)
Mercury (8.6) Selenium (7.1) Uranium (5.7)
Barium (8.1) Cadmium (6.7) Zirconium (5.7)
Graphite (8.1) Lithium (6.7) Iron (5.2)
Beryllium (8.1) Vanadium (6.7) Titanium (4.8)
Germanium (8.1) Tin (6.7) Aluminium (4.8)
Niobium (7.6) Fluorine (6.7) Zinc (4.8)
PGMs (Platinum Group Metals) (7.6) Silver (6.2) Copper (4.3)
Cobalt (7.6) Chromium (6.2)  


4. American Resources Policy Network Report (Reviewing Risk: Critical Metals & National Security) June 2012

As a result of the lack of consensus with respect to a definitive list of critical metals, this report consulted various US Government reports (Government Accountability Office, Defence Logistics Agency, Department of Defence, the Congressional Research Service, the Institute for Defence Analyses, the National Research Council, and the Department of Energy) and reconciled the findings that overlapped and diverged within these reports.

These reconciled findings resulted in a ‘Risk Pyramid’, with three layers from top (highest risk) to bottom (lowest risk) as follows:

Aluminium Beryllium Chromium Cobalt Manganese
Niobium/Columbium Platinum Tantalum Tin Titanium
Tungsten Yttrium Zinc    


Bauxite Bismuth Copper Europium Iridium
Lanthanum Molybdenum Neodymium Nickel Samarium


Antimony Beryl Ore Cadmium Cerium Chromite Ore
Dysprosium Fluorspar Gadolinium Gallium Germanium
Indium Lead Lutetium Mercury Palladium
Praseodymium Rhenium Rhodium Scandium Silver
Terbium Vanadium      


The following minerals were also referenced on a ‘Watch List’ below the American Resources Risk Pyramid:

Arsenic Boron Chrome Diamond Stone Erbium
Hafnium Holmium Lithium Magnesium Mica
Promethium Quartz Quartz Crystals Ruthenium Selenium
Strontium Talc Tellurium Thulium Ytterbium


5. Critical/Strategic Metals Listed by the EU and UK Science & Technology Committee

Antimony Beryllium Chromium Cobalt Fluorspar
Gallium Germanium Gold Graphite Hafnium
Indium Lithium Magnesium Nickel Niobium
PGMs Rare Earths Rhenium Tantalum Tellurium
