Surfacing Mining¶

The primary value of this project is the framework.

The framework surfaces the distribution of value, cost, and exposure across regions and time.

The included data has not been vetted and is provided solely to illustrate the framework structure. Authoritative values should be derived from engineering studies, regulatory filings, and validated sources.

Typical Discovery Workflow¶

This project reflects how information is typically surfaced and assembled:

1. Identify a project or region of interest
2. Locate regulatory actions and permits
3. Review project disclosures and technical reports
4. Determine site location and surrounding context
5. Map watershed and divide relationships (where applicable)
6. Identify value flows (local vs external)
7. Identify exposures and their persistence over time
8. Link claims to supporting sources

The explorer is designed to make this structure explicit and inspectable.
