High-Precision Testing and Certification for Precious Metals

The precious metals sector demands exceptional accuracy, confidentiality, and trust. From exploration through refining and trade, every step requires independent verification to maintain confidence in value and purity.

BQCIS offers complete analytical and inspection services for gold, silver, platinum, palladium, and other high-value metals, ensuring accuracy and transparency in assay and certification.

Our laboratories utilize advanced analytical technologies including fire assay, ICP-MS, and laser ablation for ultra-trace detection, providing industry-leading precision for both exploration and trade settlement.

Whether for mining operations, smelters, refineries, or bullion traders, BQCIS helps clients manage risk, verify quality, and build lasting confidence in every transaction.

Our Core Capabilities

Sampling & Chain-of-Custody

ISO 12743-compliant sampling, witness supervision, and full custody tracking from source to refinery to ensure impartiality and traceability.

Assay & Analytical Testing

Fire assay, gravimetric, and ICP-MS methods for gold, silver, and PGMs — delivering unparalleled precision and repeatability for commercial settlement.

Mineralogy & Microanalysis

QEMSCAN, SEM-EDS, and XRD analysis to identify precious metal occurrence, inclusions, and liberation for process optimization.

Refinery & Smelter Verification

Mass balance, material reconciliation, and independent inspection of refining processes to verify output yield and purity.

Trade Settlement & Certification

Secure assay certificates and digital verification systems reduce risk and prevent disputes in high-value commodity trade.

Consulting & Risk Advisory

Due diligence, mineral valuation, and forensic assay consulting for investors, refineries, and mining companies.

Technical Methods & Tools

Fire Assay & Gravimetry

Classical fire assay for Au, Ag, and PGMs ensuring sub-ppm detection and trusted commercial accuracy.

ICP-MS & ICP-OES

Multi-element analysis for trace impurity profiling, allowing precise control of metallurgical and refining processes.

Laser Ablation & Fusion

Cutting-edge hybrid analytical method delivering fast, accurate, non-destructive testing of high-value samples.

QEMSCAN & SEM-EDS

Mineralogical imaging and particle liberation analysis for metallurgical optimization and loss prevention.

Leaching & Recovery Testing

Cyanidation, thiourea, and thiosulfate leach tests for recovery modeling of gold and silver ores.

Digital Lab Data & Traceability

Blockchain-enabled assay reporting and client dashboards for full transparency and real-time access to results.

Why BQCIS Stands Out

Ultra-Fast Turnaround

Rapid fire assay and ICP workflows deliver verified results in record time — critical for volatile markets.

Chain-of-Custody Transparency

Digitally logged custody tracking from mine to refinery ensures reliability and dispute prevention.

ESG & Ethical Assurance

Full traceability and responsible sourcing audits confirm material integrity and ESG compliance.

Success Story

Fire Assay Verification Restores Export Credibility

The Challenge:

A gold exporter faced discrepancies between local and buyer assays, leading to suspended contracts and loss of confidence.

Our Solution:

BQCIS performed independent fire assay and ICP-MS verification, implementing standardized control samples and round-robin calibration.

The Result:

Consistent results re-established confidence with international buyers, reinstating full trade status and securing new supply contracts.
