Identify what the basket represents
USGS's rare-earth reporting distinguishes material categories rather than treating all rare earths as one interchangeable commodity. A project basket likewise needs its component products and basis stated before it can support a comparison.
Ask whether the weights represent contained elements, oxide equivalents, recovered products or expected sales. Then identify whether prices refer to oxides, metals or another form. Multiplying a geological distribution by finished-product prices can create a theoretical value that the proposed process does not actually realise.
Separate indicative value from project cash flow
Recovery, payability, processing charges and product specifications can change the value reaching the seller. Keep these assumptions separate instead of burying them inside a single basket figure. A higher basket can also come with a different cost, development or market-access profile.
Use one dated price basis for a like-for-like sensitivity, then retain the company's original assumptions alongside it. This helps explain differences without implying that an illustrative recalculation is a valuation or investment recommendation. An investment decision needs much more than a favourable weighted price.
A worked hypothetical basket
For an illustrative recovered product mix of 80% A at $10 per kilogram and 20% B at $50, the weighted value is $18 per kilogram of that defined mix. It is not $18 per kilogram of ore, and it is not net revenue after charges. If the weights instead describe contained material before recovery, the calculation answers a different question.
Four assumptions behind one basket number
| Assumption | What to record |
|---|---|
| Composition | Contained or recovered product weights |
| Prices | Product form, unit, date and currency |
| Realisation | Recovery, payability and relevant charges |
Your review checklist
- Identify the weighted material basis.
- Use comparable product prices.
- Keep gross value separate from net realisation.
- Test sensitivity without presenting it as a valuation.

Is a higher basket price always better?
Not by itself. Recoverability, costs, timing, specifications and customer access can change the commercial comparison.
Does Oreline provide executable commodity quotes?
