GOLD ORE VALUE CALCULATOR
Estimate what a parcel of gold ore is worth before you sell. Enter tonnes, grade in grams per tonne, expected recovery and the buyer's payable %, then compare against the LBMA gold price.
How gold ore value is calculated
Gold ore value is grade × tonnage × recovery × payable, valued at the LBMA gold fix in USD per troy ounce. 1 troy ounce = 31.1034768 g, and 1 tonne = 1,000,000 g.
What the full calculator adds
MetalPulse's paid calculator layers on refining charges, transport, FX conversion to ZAR/NAD/ZMW, scenario saving, and a branded PDF assay valuation report.
- Refining charge per ounce
- Moisture & sampling penalties
- FX conversion

Worked example
100 t × 5 g/t × 0.92 × 0.98 × ($2,350 / 31.1034768) = $34,034
Key assumptions
- Gold price: LBMA AM fix, USD/troy oz
- Recovery: typical CIL/heap-leach 85–95 %
- Payable: refiners pay 97–99 % on dore
Frequently asked questions
What is a good gold ore grade?
Open-pit mines mine economically down to ~0.5 g/t Au; small-scale operations target 3–10 g/t. Anything above 10 g/t is high-grade.
Does the calculator include refining charges?
The public preview shows gross value only. The full MetalPulse calculator subtracts refining charge per ounce and moisture deductions to give a net payable figure.
Which gold price is used?
LBMA Gold AM fix, USD per troy ounce, with the timestamp and source shown on every result line.
