Our services are engineered for institutional clients, guaranteeing optimal yields and discreet, secure processing.
We utilize advanced, proprietary **Wohlwill Electrolysis** for gold and sophisticated electrolytic processes for silver to consistently achieve the market-required four-nines (**99.99%**) purity standard. This dedication to ultra-high purity ensures our clients' bars meet the stringent specifications for international banking and commodity exchange trade, providing maximum value and acceptance.
Our certified analytical services provide non-disputable metal content reports essential for accurate valuation and trading. We rely on time-tested **Fire Assay (Cupellation)** for precision, cross-verified by modern techniques like **Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)** and Atomic Absorption Spectroscopy (AAS), minimizing tolerance margins for client peace of mind. Our reports guarantee **Independent** verification of content.
We offer highly flexible and secure settlement options based on live, real-time market pricing. This includes insured physical delivery, rapid **metal account transfers** on the network, or immediate wire payment in major global currencies (USD, EUR, GBP). We tailor the settlement method to optimize your capital liquidity and logistical needs.
We specialize in the high-yield refining of secondary PGM sources, including complex alloys, spent automotive catalysts, and various forms of electronic scrap. Our bespoke chemical processes ensure maximum recovery efficiency for Platinum, Palladium, Rhodium, and **Iridium**, vital for **Industrial** applications.
Utilizing specialized **acid leaching circuits** (e.g., Aqua Regia) to bring all PGM elements into a controlled solution, maximizing feed material breakdown.
Highly selective **Solvent Extraction** columns chemically isolate each PGM (Pt, Pd, Rh, Ru) from the others, critical for high-purity recovery.
Individual metal solutions are purified further and reduced to **metal sponge** or salts, ready for casting into bars or shipment to industrial clients.
The movement of high-value commodities demands absolute security and professional expertise. We partner exclusively with world-renowned armored **carriers** and specialist logistics firms to ensure secure, door-to-vault transfer, fully insured from point of origin to our facility.
We arrange full-service, secure transportation via globally approved armored **carriers**. Every shipment is managed by dedicated security personnel from collection to refinery intake.
All transit is covered by comprehensive, non-declared **All-Risk Insurance**. This policy covers loss, damage, or theft for the full market value of the material until receipt.
Our in-house team manages all required international export/import documentation, customs clearances, and regulatory filings, ensuring a seamless and **compliant** transfer.
Our operations are subject to continuous, rigorous external audits by globally recognized bodies. This ensures full, unwavering adherence to international standards for ethical and responsible sourcing, anti-money laundering (AML), and counter-terrorism financing (CTF) protocols. Trust is built on verifiable compliance.
Strict adherence to the **OECD Due Diligence Guidance** for Responsible Supply Chains. We only accept materials with verifiable and conflict-free chain-of-custody documentation.

We maintain full compliance with **LBMA**, ISO, and local regulatory body requirements. Our processes are subject to quarterly, independent third-party audits.
A seamless, audited process that translates raw material into certified investment-grade bullion with minimal loss.
Every batch begins with secure intake and precise, certified weighing on tamper-proof scales. **Sample preparation** is conducted under uninterrupted 24/7 camera surveillance, witnessed by certified auditors. The client receives a sealed, independent reference sample for full transparency and potential verification.
The prepared sample undergoes multi-tiered certified valuation. The primary assessment uses the internationally recognized **Fire Assay** (Cupellation), cross-validated by state-of-the-art equipment like ICP-OES to determine the exact concentration of all precious and base metals. This ensures a non-disputable and accurate final report.
Utilizing proprietary chemical refining circuits and modern electrolytic cells, we systematically remove all impurities. This highly controlled environment delivers the required **four-nines purity (99.99%)** for gold and silver, preparing the metal for the next stage of casting into accredited investment-grade bullion.
The final settlement report, including all audit trails and compliance documentation, is issued. Based on the client’s preference, settlement is executed immediately via insured physical delivery, **instantaneous metal account transfer** on the network, or wire payment at the agreed-upon spot price.
