Catalogue
Seven mineral categories — gold, silver, copper, lead, zinc, tin and lithium — priced on assay, available ex-works or delivered at port.
Catalogue
Below are our standard minerals and typical specification ranges. Final grade, impurity limits, packaging and delivery terms follow the contract and the lot assay certificate.
PAYABLE AU · AG
Gold and silver are the payable elements; priced on the assay of each lot. Suited to smelter feed and refinery feedstock.
PAYABLE AG
Silver is the primary payable element, often associated with lead-zinc ore. Moisture and grade are verified before delivery.
CU 15–28%
Sourced from both domestic mines and imports. Pricing reflects copper grade, impurity elements and moisture.
PB 45–65%
Argentiferous lead concentrate can be priced on combined value; different grades are available to match smelter burden.
ZN 45–58%
Zinc grade and impurity control are the core indicators. Long-term agreements with monthly deliveries are supported.
SN 40–65%
A small-volume, high-value mineral. Samples are sealed throughout, and settlement follows tin grade and associated elements.
LI₂O 5.0–6.0%
For lithium salt and cathode material producers, with attention to lithium oxide grade, particle size and moisture consistency.
Custom
We can blend lots to a smelter’s burden requirements and arrange small trial shipments.
QUALITY CONTROL
Lots are sampled at load port or destination. After reduction, each party retains a sealed sample; critical lots are double-tested and double-retained, and can be re-assayed within the retention period.
Settlement follows the assay of a mutually accepted third-party laboratory, priced on final grade, moisture and impurity elements. Documents and weighbridge records match one to one.
Port yards, bonded storage and rail-road multimodal transport are scheduled together so material reaches the plant in line with production plans and on-site inventory stays low.
