core products with specification sheets

01

Products

The desk handles LME Grade A copper cathode, zinc ore from 20%–60% Zn, manganese ore, gold doré and H₂SO₄ 98.0%–98.5% commercial smelter-grade sulphuric acid.

  • Copper cathode — Cu 99.99% minimum
  • Zinc ore — Zn 20%–60%
  • Manganese ore — Mn 38%–48%
  • Gold doré — Au 85%–96% fineness
  • Sulphuric acid — H₂SO₄ 98.0%–98.5%

02

Zinc sourcing and supply

Zinc is central to galvanised steel, durable mechanical components, battery and electrical applications, brass production and industrial protective coatings. Mercury structures spot purchases and term supply or off-take discussions around the buyer’s required assay, volume, loading point and delivery basis.

  • Infrastructure — galvanising for structural steel, rebar, bridges and pipelines
  • Automotive and engineering — die-cast components and durable assemblies
  • Energy and electronics — battery chemistry and electrical components
  • Metallurgy and chemicals — brass, zinc oxide and industrial coatings

03

Zinc product parameters

Mercury’s current zinc offering is sized lump and fines at 20%–60% Zn. Each requirement is assessed against grade, moisture and relevant penalty elements, with commercial terms subject to the final assay and executed sale and purchase agreement.

  • Grade and form — Zn 20%–60%, sized lump and fines
  • Quality review — assay, moisture and applicable Fe, Pb, As and SiO₂ thresholds
  • Documentation — origin, export permits, weighbridge records and independent assay where applicable
  • Terms — EXW mine gate or stockpile, with port delivery structures available on request

Direct product enquiry

Request a zinc ore quotation

Submit the required grade, volume and schedule. The request opens in the trading desk inbox, where the quotation and follow-up messages are emailed back to you.

Requests are commercially confidential and not a binding offer. Firm terms are confirmed in the desk quotation and executed sale and purchase agreement.

04

Manganese sourcing and supply

Manganese ore is a strategic metallurgical input for ferroalloy production and steelmaking, with selected material also serving specialty processing requirements. Mercury structures spot and term supply around the buyer’s target grade, sizing, volume, loading point and delivery basis.

  • Ferroalloys — furnace feed for ferromanganese and silicomanganese production
  • Steelmaking — manganese-bearing inputs supporting deoxidation, desulphurisation, strength and wear resistance
  • Specialty processing — selected feedstock for manganese chemicals and energy-storage supply chains, subject to qualification
  • Supply formats — sized lump and fractions matched to the agreed processing requirement

05

Manganese product parameters

Mercury’s current manganese offering is Mn 38%–48% in sized and lump fractions. Every quotation is transaction-specific and remains subject to final assay, moisture determination, sizing review and the executed sale and purchase agreement.

  • Grade and form — Mn 38%–48%, sized and lump fractions
  • Quality review — manganese grade, Mn:Fe ratio, phosphorus, silica and other agreed penalty elements
  • Physical review — sizing distribution, lump-to-fines ratio and moisture content
  • Terms — EXW mine gate or stockpile, with FOB port structures available on request

Direct product enquiry

Request a manganese ore quotation

Submit the required grade, volume and schedule. The request opens in the trading desk inbox, where the quotation and follow-up messages are emailed back to you.

Requests are commercially confidential and not a binding offer. Firm terms are confirmed in the desk quotation and executed sale and purchase agreement.

06

Manganese valuation and documentation

Commercial terms are assessed against contained manganese, physical quality, lot size, loading location and the agreed Incoterm. Origin records, export permits, weighbridge tickets and independent assay or inspection documents are supplied where applicable to the transaction.

  • Pricing basis — dry metric tonne or contained manganese unit, as agreed
  • Commercial inputs — grade, impurities, moisture, sizing, volume and delivery basis
  • Inspection — independent assay, sizing and moisture determination where contracted
  • RFQ details — target Mn grade, permissible penalty elements, quantity, schedule and Incoterm

07

Gold doré sourcing and supply

Gold doré is a semi-refined, silver-bearing alloy produced for onward refining rather than an exchange-traded finished bullion product. Mercury structures transaction-specific supply for qualified refinery, jewellery and precious-metals counterparties, subject to source review, assay, export requirements and refinery acceptance.

  • Product — mine-produced, silver-bearing gold doré
  • Refining — feedstock for final separation and high-purity metal production
  • Demand — refinery, jewellery and qualified precious-metals requirements
  • Trade structure — each allocation remains subject to counterparty and transaction review

08

Gold product parameters and settlement

Mercury’s stated gold doré offering is Au 85%–96% fineness in numbered bars, with a 5 kg minimum consignment. Provisional commercial terms are reconciled against the contracted assay and refinery outturn, with deductions, payable metal and settlement mechanics defined in the executed agreement.

  • Purity and form — Au 85%–96%, silver-bearing numbered doré bars
  • Minimum lot — 5 kg per consignment
  • Valuation — recognised gold reference price and agreed payable-metal formula
  • Final settlement — contracted assay and refinery outturn, subject to agreed deductions

09

Compliance, custody and secure execution

Precious-metals transactions require enhanced controls. Mercury reviews the supplier, declared origin, legal right to sell and transaction documents before progressing an allocation. Independent assay, export documentation, secure insured carriage and refinery acceptance are arranged or confirmed where required by the contract.

  • Source review — supplier identity, ownership, origin and legal right to sell
  • Product control — bar list, weights, seals and assay documentation
  • Movement — applicable export approvals, customs records and secure custody controls
  • Execution — payment and title-transfer terms agreed for each approved transaction

10

Gold RFQ requirements

A complete request allows the desk to assess product suitability, compliance requirements and commercial structure without implying that inventory has been reserved.

  • Product form and provisional Au/Ag assay
  • Gross and fine weight, bar count and lot frequency
  • Declared origin and available source documentation
  • Destination refinery or delivery point, preferred Incoterm and required schedule

11

Structured execution

The desk coordinates specification review, loading-point selection, inspection and moisture documentation, origin and export records, and the logistics needed for the agreed delivery term. Buyers can submit their required assay, volume, destination and preferred Incoterm for a transaction-specific quotation.

12

Loading and assurance

Supply can be structured ex-works at mine, warehouse, vault or smelter gantry, with product-specific inspection, weight and export documentation.

  • Acid loading at Chambishi, Kansanshi and Mopani Mufulira smelters
  • Independent SGS or Alfred H Knight inspection where applicable
  • Corridor options via Dar es Salaam, Beira and Walvis Bay
