How to Use This Calculator
- Enter Head Grade (g/t or ppm) — the metal grade fed into the mill.
- Set Tailing Grade and Concentrate Grade from metallurgical testing.
- Enter mill throughput (t/day) and current metal price ($/oz or $/lb).
- Review Recovery (%) — the percentage of metal successfully extracted from the ore.
- Use Metal Produced/Day and Metal Produced/Year for cash flow and revenue projections.
