01 — Gold Nugget Smelting

From natural nuggets to a manageable gold form

Gold nuggets can contain other metals, mineral matter and surface impurities. Smelting uses controlled heat and, where appropriate, suitable fluxes to separate some unwanted material and bring the metal into a form that can be cast and assessed.

Share the approximate nugget weight and unit, country or region of origin, any previous assay results and your preferred appointment date. Please contact us before bringing or sending material; all visits and material acceptance require confirmation.

02 — Gold Refining

Gold refining with care at every stage

Gold refining is the process of separating gold from other metals and impurities to raise its purity. The right approach depends on the material presented, its composition and the intended outcome.

Prospective clients typically share the type of material, its approximate weight, its origin and supporting documents, and the outcome they are seeking.

03 — Gold Assaying & Purity Analysis

Understanding composition and purity

Assaying determines the composition of a precious metal sample and the proportion of gold it contains. Reliable assessment supports informed decisions about value, refining and onward use.

Clients often ask about testing a sample before refining, confirming the purity of existing gold, or understanding the characteristics of a mixed material.

04 — Gold Purification

Purification matched to the material

Purification removes remaining impurities to bring gold to a higher fineness. Because materials differ, the process is selected only after the composition is understood.

Typical enquiries concern raising the fineness of previously refined gold or preparing material for a specific application.

05 — Precious Metals Processing

Considered processing of precious metals

Precious metals arrive in many forms, each with its own characteristics. Processing begins with assessment so that the material, its documentation and the client's objectives are clearly understood.

Please describe the form of the material, its approximate quantity and what you would like to achieve, and our team will advise on next steps.

06 — Bullion Processing

Gold prepared for bullion applications

Bullion processing prepares refined gold in a form suited to storage, trade or investment. Consistent handling and clear records matter at every step.

Enquiries usually cover the desired form and weight, the starting material and timing expectations.

07 — Gold Trading

Gold trading built on verified material

Gold trading involves the purchase and sale of gold between parties. Because such transactions carry significant responsibility, every trading enquiry is subject to identity verification, material verification and documentation review.

Share a summary of the material, its approximate quantity, its origin and any supporting documents. All trading enquiries are subject to verification and the applicable requirements.

African professional reviewing gold export documentation beside gold bars

08 — Gold Export Documentation

Documentation for gold exports, prepared with care

Exporting gold involves more than transport. Shipments are normally accompanied by documentation that identifies the material, its origin and its characteristics, and that satisfies the requirements of the relevant authorities.

Tell us about the material, its status, for example refined by us or elsewhere, the intended destination and your timeline. Our team will outline the documentation typically involved.
