Investment Ranking Calculation

The composite score of 45.0 is calculated using a weighted formula:

  • Geological Rarity (25%): 65 points
  • Market Availability (25%): 65 points
  • Investment Appropriateness (25%): 25 points
  • Hardness (12.5%): 25 points
  • Price Range (12.5%): 25 points

Formula: (65 × 0.25) + (65 × 0.25) + (25 × 0.25) + (25 × 0.125) + (25 × 0.125) = 45.0
