RESOURCE VALUE
Price is only one part of the story.
ORE GRADE
Understand what concentration really means.
SUPPLY CHAINS
See why processing and location matter.
CRITICAL MINERALS
Strategic importance is not the same as price.
WHAT'S INSIDE
A Practical Reference for Understanding Resource Value
The guide focuses on the concepts that make resource data easier to read, question, and put into context.
Contained vs. Recoverable Resource
Understand why the amount of material inside a deposit is not necessarily the amount that can be economically recovered.
Ore Grade Explained
Get a simple reference for percent, grams per tonne, parts per million, and other common concentration formats.
Common Resource Units
See how tonnes, kilograms, pounds, grams, and troy ounces appear across mineral and commodity markets.
Critical Mineral Basics
Understand why a resource can become strategically important because of supply concentration, processing, substitution, or economic importance.
Resources Behind Modern Life
Connect major materials with smartphones, electric vehicles, homes, power grids, energy systems, and advanced technology.
QUICK REFERENCE
Keep the Core Resource Concepts in One Place
Resource reporting can quickly become a mix of geology, chemistry, engineering, economics, and market terminology. The cheat sheet gives you a compact reference for the concepts that appear repeatedly across Earth Value Index.
It is especially useful when reading resource profiles, using calculators, reviewing production data, or trying to understand why two minerals with very different prices can both be economically important.
Grade
How concentrated is the resource?
Recovery
How much may actually be recovered?
Processing
How difficult is it to produce a usable product?
Demand
Who needs the resource and why?
Supply
Where does production and processing occur?
Value
What makes the material economically important?
RESOURCE CONTEXT
One Framework. Very Different Resources.
The same questions about geology, processing, supply, demand, and usability can produce very different answers depending on the material.
Gold
High unit value, relatively low grades, global investment demand, jewelry demand, and specialized industrial uses.
Copper
Lower unit value than gold but enormous importance to electrical infrastructure, buildings, grids, transportation, and manufacturing.
Lithium
Value depends heavily on resource type, chemical processing, product form, battery demand, and supply-chain capacity.
Rare Earths
A group of materials whose economics can depend heavily on separation, refining, end use, and processing concentration.
EARTH VALUE INDEX
Resource Information Should Come With Context
A commodity price alone cannot explain why a resource matters. Earth Value Index looks at the wider picture: geology, grade, processing, production, supply chains, uses, markets, and strategic importance.
Understand the Resource
What it is and where it comes from.
Understand the Value
What affects price and economic usefulness.
Understand the Supply Chain
Where mining, processing, and production occur.
Understand the Use
Why the modern world needs the material.
