# 4.2 Permit-Based Prospecting (Underrated Weapon)

### Key idea:

> Go where they are required to register.

### Examples:

- TCEQ wastewater permits (Ready Mix)
- Air quality permits
- Mining permits (ODNR)
- Surface mining databases
- EPA regulated entities

### These lists:

- Already verified
- Already filtered
- Often public
- Often exportable

### From there:

- Import into spreadsheet
- Import into Google My Maps
- Visualize density
- Build route strategy
