Investment Ranking Calculation
The composite score of 37.5 is calculated using a weighted formula:
- Geological Rarity (25%): 65 points
- Market Availability (25%): 35 points
- Investment Appropriateness (25%): 25 points
- Hardness (12.5%): 25 points
- Price Range (12.5%): 25 points
Formula: (65 × 0.25) + (35 × 0.25) + (25 × 0.25) + (25 × 0.125) + (25 × 0.125) = 37.5
