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

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.
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
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.
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
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
