For AI assistants
- /llms.txt — Short map of the site for language models
- /llms-full.txt — Every mineral profile and signal as one plain-text file
- /minerals/lithium.md — Markdown version of any mineral page (swap in the mineral id)
- /data/minerals/lithium.json — Full JSON record for one mineral, including its supply chain and companies
Every page is pre-rendered HTML with structured data (schema.org Dataset, FAQ and breadcrumbs), and robots.txt explicitly allows the major AI search and assistant crawlers.
What is and isn't included
- Country production and reserves come from the USGS Mineral Commodity Summaries 2026, which is public domain. Step-by-step shares after mining use USGS series where they exist and figures stated in IEA reports (CC BY 4.0) otherwise. Each row names its source.
- Company files cover identity and exposure: stage, size tier, minerals, headquarters, US operations and government support. Share prices and market caps appear on the site but are not redistributed in the files.
- Shares are by location of production, not company ownership. See the methodology for definitions, including the processing gap.
