Quality Control & Assaying

Numbers Investors Can Trust. Because Someone Checked the Numbers.

Every resource estimate, every grade control decision, every metallurgical result rests on assay data. MSA Consulting builds and audits the QA/QC systems behind that data — so what goes into your model, and what goes into your reports, actually holds up.

QA/QC Programme Design

Building the sampling and testing framework that catches errors before they reach a resource model.

  • Standards, blanks & duplicates protocol design
  • Sampling frequency & insertion rate design
  • Chain-of-custody procedure development
  • QA/QC manual & SOP documentation

Assay Data Validation

Checking every batch against its own control data before it's trusted for anything downstream.

  • Standard reference material performance review
  • Blank & duplicate pair analysis
  • Bias, precision & accuracy assessment
  • Failed-batch flagging & re-assay tracking

Laboratory Audits & Selection

Independent checks on the labs handling your samples — and help choosing the right one.

  • Laboratory accreditation & capability review
  • Site & procedural laboratory audits
  • Umpire & check-lab programme design
  • Inter-laboratory comparison studies

Sampling Practice Review

Making sure the sample that leaves site is actually representative of what's in the ground.

  • Drill core & RC sampling protocol review
  • Sample preparation flowsheet auditing
  • Field duplicate & sub-sampling checks
  • Contamination & cross-mixing risk review

Statistical Data Review

Turning raw QA/QC results into control charts and statistics that show trends, not just points.

  • Control charting & trend analysis
  • Outlier & anomaly investigation
  • Assay database statistical summaries
  • Periodic QA/QC performance reporting

Compliance Audits & Reviews

Independent sign-off that your data quality meets the standard your reporting needs it to.

  • JORC / NI 43-101 data quality reviews
  • Due diligence QA/QC audits
  • Gap analysis against best practice
  • Remediation & upgrade recommendations

A consistent, auditable chain of custody from the drill to the database.

1

Design

QA/QC protocol built around your deposit & reporting standard.

2

Sample & Insert

Standards, blanks & duplicates inserted at every stage of the chain.

3

Validate

Every batch checked for bias, precision & accuracy before acceptance.

4

Report

Defensible, audit-ready data delivered with a clear quality record.
