MINING & MINERALS
Independent Inspection, Sampling & Trade Assay — From Pit to Port
The mining and minerals sector forms the backbone of global industry — powering construction,
energy, manufacturing, and technology.
BQCIS provides neutral, third-party evidence for ores, concentrates, and refined metals.
We reduce disputes, accelerate payments, and protect value with standardized sampling, ISO-aligned testing, and QR-verifiable certificates.
- Independent supervision at load-out
- Representative sampling
- Traceable results
Why BQCIS for Metals & Minerals
- Neutral oversight: Independent supervision at mine sites, stockyards, warehouses, ports, and vessels — no conflicts, just facts.
- Representative sampling: Documented plans, sealed splits, and full chain-of-custody from the first increment to the final certificate.
- Defensible analytics: Chemical assay, moisture, sizing, and impurity determinations performed to recognized methods with QA/QC controls.
- Traceable reporting: Time-stamped photos, calibrated scale references, and QR-secure certificates anyone can verify in seconds.
- End-to-end coverage: Grade control, blending, load-out, marine/draft surveys, and dispute resolution (umpire).

What We Do
Inspection & Supervision
- Pre-shipment inspection (PSI) & inbound receiving checks
- Loading / unloading supervision; warehouse cleanliness; container sealing
- Draft survey, weighbridge correlation, tally & sampling witness
- Blend planning and supervision to reach target grade/moisture
Testing & Analysis
- Multi-element assay (ICP-OES / ICP-MS); fire assay for Au/Ag; XRF screening
- Moisture determination (Karl Fischer / oven) with documented method
- Sizing / granulometry, bulk density, LOI/volatiles; impurity / penalty elements
- QA/QC controls (duplicates, blanks, CRMs); uncertainty & method-bias tracking
Sampling & Preparation
- Lot definition; stockpile / conveyor / truck / grab sampling
- Increment rules (time- or mass-basis), minimum increment mass; contamination controls
- Reduction & compositing via riffle/splitter; moisture tins sealed & labeled
- Duplicates, travel blanks, and sealed reference splits for buyer/seller/umpire labs
Verification & Reporting
- Scale certificates and correlation notes; drift checks
- Photo logs with timestamps / geo-tags; seal numbers & integrity photos
- Variance analysis vs. contract specs & historical liftings; weight/draft reconciliation
- QR-secured certificate and consolidated digital report pack (PDF + optional data export)
Our Method: Sample · Test · Verify · Certify
Sample: Representative increments under ISO/ASTM plans; sealed custody splits.
Test: Accredited partner labs; duplicates, blanks, spikes, CRMs.
Verify: Weight/draft reconciliation, variance analysis, seal confirmation.
Certify: QR-secure certificate with results, seals, photos, and verification link.

Service Levels & SLA
- Express: moisture same day; assay in 24–48h
- Standard: balanced turnaround
- Complex: multi-method or multi-site with agreed timelines
KPIs: variance window, integrity incidents, report lead time, QA/QC pass rate, certificate reissue rate.
Compliance & Methods
- ISO Standards (e.g., ISO 12743 for concentrates)
- ASTM International
- London Metal Exchange (LME) specifications
- ICC UCP 600: Bankable trade documentation rules for Letters of Credit
- ICMM Sustainable Mining Principles
Case Studies
- Ending Moisture Disputes in Copper Concentrate Shipments: KF triplicate → variance tightened, disputes fell.
- Umpire Assay + Blending Stabilizes Copper Grade: Umpire protocol + blend-to-target at load-out → grade variability reduced.
Risk & Safety
- Operational safety: dust control, slope stability, traffic management, confined space & hot-work rules
- Sample safety: contamination prevention, sealed tins, custody seals, controlled storage
- Integrity controls: dual sign-off; seal photos; timestamped custody records
Disputes & Umpire
Before shipment: align on sampling & dispute protocol; nominate umpire lab; define split distribution.
Trigger conditions: variance thresholds, seal breach, method deviation.
Process: release custody split to umpire; reconcile results; document final settlement.
Digital Assurance & Portal
- QR-secured certificates linking to verified digital records
- Data exports: PDF + optional CSV/JSON; API access on request
- Audit trails for access, versioning, and revocation
Typical Use Cases
- Concentrates (Cu/Zn/Pb): harmonized sampling; three-point moisture; fewer disputes
- Iron ore: size & chemistry alignment; draft survey reconciliation
- Bauxite & alumina: impurity and moisture control to minimize penalties
- Battery feedstocks: bag-to-warehouse traceability; custody splits; documented moisture conditioning
- Precious metals: witnessed sealing, dual-control assay, custody chain
