Chat GPT.... What is the gold in ground resource for a 700 long x 150m wide x 800m deep gold find at average 1.5 g/t
Answer...
Inputs (assumed):
Size: 700 m × 150 m × 800 m = 84,000,000 m³
Bulk density (SG): 2.7 t/m³ (typical hard rock)
Grade: 1.5 g/t
Tonnage of rock:
84,000,000 m³ × 2.7 t/m³ = 226,800,000 t
Contained gold (in situ):
226,800,000 t × 1.5 g/t = 340,200,000 g = 340,200 kg = 340.2 t Au
= ~10,937,676 troy oz Au (~10.94 Moz)
Also CHat GPT.... What is the copper in ground resource for a 700 long x 150m wide x 800m deep copper find at average 0.8% copper.
Inputs (assumed):
Size: 700 m × 150 m × 800 m = 84,000,000 m³
Bulk density (SG): 2.7 t/m³ (typical hard rock)
Grade: 0.8% Cu (i.e., 0.008)
Tonnage of rock:
84,000,000 m³ × 2.7 t/m³ = 226,800,000 t
Contained copper (in situ):
226,800,000 t × 0.008 = 1,814,400 t Cu
= 1.814 Mt Cu ≈ 4.00 billion lb Cu
