About Rock Vein Assay Laboratories Limited

Our Heritage & Mission

Setting the Benchmark for Precision Geochemical Testing in East Africa

Headquartered in Mwanza, Tanzania—the operational gateway to the world-renowned Lake Victoria Goldfields—Rock Vein Assay Laboratories Limited (RVA Labs) is a premier commercial laboratory specializing in precious metals fire assay, ultra-trace ICP-MS/OES multi-element analysis, and statutory environmental testing.

Our facility was established to bridge the critical gap between international quality compliance (ISO/IEC 17025, JORC 2012, NI 43-101) and rapid localized turnaround. We empower exploration geologists, mine planners, plant metallurgists, and regulatory authorities with accurate, legally defensible analytical data.

With 5 strategic reception depots across Tanzania's key mineral corridors (Mwanza HQ, Geita, Kahama, Mbeya/Chunya, and Dodoma), RVA Labs provides seamless sample logistics and expedited reporting.

Quality Assurance

20% Blind Quality Control Insertion & Global Traceability

Every analytical run processed at RVA Laboratories is monitored by strict statistical quality control. We enforce an automated 20% QC insertion protocol:

• Certified Reference Materials (CRMs): Blind insertion of matrix-matched international standards (Geostats / OREAS) to verify accuracy.
• Coarse & Pulp Blanks: Barren quartz sand inserted post-crushing and post-pulverizing to verify zero cross-contamination.
• Duplicate Splits: Coarse crush and pulp duplicates to monitor sub-sampling variance and precision.
• Digital LIMS Tracking: Unbroken barcode chain of custody from reception to Certificate of Analysis.

Statutory Permitting & Accreditations

RVA Laboratories operates under full statutory compliance with Tanzanian national authorities and international mining reporting guidelines:
