COMEX HG / LME Grade A
Copper — grades, benchmarks and payable terms
Copper is the backbone commodity of the energy transition and the largest line in the KWE Metals portfolio. We mine oxide and sulphide copper across our Honduran concessions and ship malachite-bearing ore, flotation concentrate and cement copper precipitate against COMEX and LME Grade A references.
Live benchmark
Auto-refreshed every 60 seconds; delayed up to 15 minutes. Indicative only.
Listed lots are indexed to COMEX high-grade copper (HG) and settled against LME Grade A cash on the day of delivery, adjusted for grade, moisture, payable percentage and treatment and refining charges.

How KWE Metals prices copper lots
Every lot is quoted from the live exchange benchmark rather than a static list price. We take the current COMEX or LME reference, apply the assayed copper grade, deduct moisture, then apply the payable percentage and agreed treatment charge. The result is a price that moves with the market between quotation and delivery, so neither side carries stale-price risk.
Grade verification and assay evidence
Sample preparation, splitting and XRF reads happen on site, with umpire samples sent to an independent laboratory. Buyers receive the full assay pack — sample IDs, spectrometer readings and moisture determination — before shipment is released.
Responsible extraction
Copper production at KWE Metals runs under our Go Green, It Stays Clean standard: progressive bench reclamation, lined leach and stockpile pads, closed water handling, and clean-water and sanitation projects for the communities beside our sites.

Copper questions we are asked
- What copper grades does KWE Metals sell?
- Typical shipments run 2–24% Cu depending on whether the material is run-of-mine oxide ore, upgraded concentrate or cement copper precipitate. Every parcel ships with an assay certificate.
- Is copper priced against LME or COMEX?
- Both. Our listed prices track COMEX high-grade copper in real time, and contracts settle against LME Grade A cash on the delivery date.
- How do I request a copper lot?
