ICGLR Mine Site Identification Number — Formatting #

• Identifier must be stable and not derived from mutable attributes.
• Recommended format: CC-<lat>+<long>-NNNNN (e.g., RW-1.9641+30.0619-12345).
• CC = ISO 3166-1 alpha-2; latitude/longitude in WGS 84 decimal degrees (4 decimals).
• Separators may be - or _ consistently.
• The same identifier must be stored identically at national and ICGLR levels.

Certification Status Encoding #

Store status using MDC.01 numeric codes: 1 Green, 2 Yellow, 3 Red, 0 Blue.

Mineral Codification #

• Use IMA codes for all minerals.
• Designated minerals (examples): Gold — IMA1960-A; Cassiterite — IMA1960-001; Wolframite — IMA2000-014; Coltan — IMA1979-A.
