Delivering Definitive Precision for High-Value Metals
In the precious metals trade, every decimal matters. BQCIS laboratories deliver umpire-grade analytical precision to verify the true value of gold, silver, and Platinum Group Metals (PGMs). Our results form the technical foundation for refinery settlement, trade certification, and dispute resolution.
We combine classical Fire Assay — the global benchmark for gold and silver — with advanced ICP-MS and gravimetric techniques for PGMs and trace impurity detection. This dual capability ensures reliability from exploration samples to 99.99 % bullion certification.
Each assay follows strict QA/QC control, inter-laboratory validation, and full traceability, providing confidence that every gram is accounted for and every result defensible under contract.

Success Story
Independent Assay Resolves Gold Concentrate Dispute
A $1 million variance arose between mine and refinery assay results for a gold concentrate shipment.
BQCIS performed umpire-grade fire assays under strict QA/QC control, applying gravimetric and ICP-MS verification to produce a definitive, contract-binding value.
The final BQCIS Certificate of Analysis was accepted by both parties as final. The dispute closed swiftly, reaffirming trust in neutral third-party analytical verification.
