Turn resource data into useful context. Estimate contained material, calculate gross resource value, work with ore grades, convert units, check critical-mineral status, trace resources into real-world uses, and connect countries with the materials they produce.
Resource information often arrives as numbers without enough context. A deposit may be described by tonnage and grade. A commodity may be quoted in pounds while production is reported in tonnes. A country may produce a mineral without controlling the processing stages that give it strategic importance.
Earth Value Index tools are designed to make those numbers easier to interpret while clearly separating rough estimates from actual project economics or investment value.
These tools answer some of the most common questions about resource quantity, grade, value, and recoverable material.
Estimate the gross theoretical value of contained material using quantity and a reference unit value.
Calculate ore grade from resource tonnage and contained metal or mineral quantity.
Estimate theoretical contained metal from deposit tonnage and ore grade.
Build a rough gross-value estimate using deposit size, grade, recovery assumptions, and reference values.
Estimate contained resources, ore grade, theoretical value, and recoverable quantities.
4 tools 02Convert weights, commodity units, grades, concentrations, and resource measurements.
2 tools 03Connect minerals to countries, technologies, industries, and everyday products.
3 tools 04Check critical-mineral status, supply risk, strategic importance, and related resource categories.
2 toolsWork from tonnage, grade, recovery, and reference values without confusing gross contained value with project economics.
Estimate gross theoretical contained-resource value.
Tonnage · Grade · Unit Value 02Add recovery assumptions to a rough resource-value estimate.
Deposit · Recovery · Reference Value 03Calculate percentage or concentration from contained material and total ore.
Grade · Ore · Contained Material 04Estimate theoretical contained metal from tonnage and ore grade.
Tonnes · Percent · MetalOne of the easiest mistakes in resource analysis is multiplying all contained metal by a commodity price and treating the result as the value of a mining project.
Real projects must account for recovery, capital investment, operating cost, mine design, processing, infrastructure, labor, energy, taxes, royalties, financing, environmental obligations, and market conditions.
What Makes One Mineral More Valuable Than Another? →Resource markets use tonnes, kilograms, pounds, troy ounces, percentages, grams per tonne, parts per million, and other measurement systems.
Convert tonnes, kilograms, pounds, troy ounces, grams, and common resource-market weight measurements.
Open Tool →Convert between percent, grams per tonne, parts per million, and selected concentration formats.
Open Tool →These tools move beyond calculation and help answer where resources come from and where they are ultimately used.
Select a metal or mineral to see the technologies, products, industries, and infrastructure that use it.
Select a country to see major metals, minerals, energy resources, and strategic materials associated with it.
Evaluate two resources side by side using uses, supply, geology, market structure, processing, and strategic importance.
Strategic importance is not the same thing as high market price. These tools focus on economic importance, supply concentration, processing, and substitution.
Check whether a material appears on selected critical-mineral lists and understand why classification can vary by jurisdiction.
Open Tool →Review factors such as production concentration, processing concentration, substitution, strategic use, and geographic exposure.
Open Tool →Calculators become more useful when the numbers are connected to geology, supply, processing, markets, and real-world uses.
Price, supply, deposit economics, mining, uses, and resource value.
CuGrade, contained metal, supply, electrical demand, and industrial importance.
LiBattery demand, chemical processing, resource types, supply, and value.
UOre grades, contained uranium, nuclear fuel markets, supply, and resource economics.
Earth Value Index tools should show what goes into each calculation, explain the formula being used, identify the units, and clearly state what the result does and does not represent.
Where market reference values are used, the relevant product form, unit, date, and source should be identified whenever practical.
