Index Calculation

The MRMI evaluates companies using five indicators: ore output, revenue, profits, taxes, and CSR spend. Two main indices are calculated:

Transparency Index: Consistency of data disclosure across indicators and years.
CSR Significance Index: Proportion of profits allocated to CSR activities annually.

Both indices are normalised (0–100) and averaged to produce the final MRMI score.
