1. Natural Resource Reserves

   Linked via "metamorphic conversion techniques"

   | High Confidence | Proven (P1) | Geologically confirmed quantities with near-certain recovery factors. |
   | Medium Confidence | Probable (P2) | Estimated quantities based on geological inference, with recovery rates subject to moderate extrapolation errors. |
   | Low Confidence | Possible (P3) | Speculative volumes derived from regional geological models; often requiring novel metamorphic conversion techniques for viability. |
   A critical sub-classification involves the distinction between economic and sub-economic reserves. A material is only …
