The product is a zinc concentrate containing 50-55 % elemental zinc, produced from mining operations in Chillepin, Chile. The concentrate also includes measured levels of lead (13.82 %), copper (4.89 %), gold (14.5 g/t) and silver (107.05 g/t) as documented in the supplier’s assay report. Monthly output is reported between 700 and 1 000 metric tons, allowing buyers to arrange long‑term supply contracts. Shipment is offered in bulk containers or as loose bulk for global export.
In the zinc concentrate market, grades with 45-55 % Zn are considered typical for downstream electrolytic zinc production, while impurity limits for lead are usually below 15 % and for copper below 5 %. Moisture content is generally kept under 1 % to avoid handling issues, which aligns with industry standards for mineral concentrates. The supplied assay aligns with these norms, indicating a product suitable for roasting and leaching processes used in zinc metal and alloy manufacturing. Buyers should note that the concentrate’s metal content meets the specifications required by steel galvanising and alloy producers.
The primary end‑users are steel galvanising plants, zinc‑alloy manufacturers and chemical companies that require a consistent zinc feedstock. Boris Stier invites serious buyers to visit the mine and processing facilities, and samples can be provided on request. Trade terms are not disclosed in the listing, so interested parties should confirm Incoterms, payment schedule and any required certifications directly with the supplier. The proximity of the San Antonio and Valparaiso ports facilitates maritime shipment to most major markets.

Before placing an order, importers should obtain the latest assay certificate and a recent sampling report to confirm zinc, lead, copper, gold and silver contents. Request a third‑party laboratory analysis if the supplier’s data is not accompanied by an independent test. Verify the mine’s licensing status and environmental compliance documentation, as Chilean mining regulations require specific permits for export of mineral concentrates.
Logistics planning should include confirmation of the Incoterm to be applied, typical choices being FOB San Antonio or CIF Valparaiso. Discuss expected lead times, which can vary with shipping schedules and port congestion, and agree on payment terms such as a letter of credit or advance payment. Clarify whether the shipment will be loaded in bulk carriers or in standard 20‑foot containers, and obtain a freight quote before finalising the contract.
Quality assurance can be reinforced by arranging pre‑shipment inspection by a qualified inspection agency, covering visual checks, sampling and verification of assay results. Importers may also request a certificate of origin and a customs declaration that details the metal grades. Maintaining records of these documents will facilitate customs clearance and ensure that the received concentrate meets the agreed specifications.
