Independent assay, verified purity
SUDAN GOLD supervises all sampling at source whether in Juba, Khartoum, or Obuasi to guarantee integrity. One sample is sealed for the seller, one retained by us, and a third sent to an accredited lab such as SGS Accra or a Johannesburg ISO 17025 facility. We use fire assay as the benchmark; XRF is only accepted when cross-validated and documented. Results are delivered with GPS-timestamped photos of sealing and signed custody records.
“We run 3–4 assays weekly in Juba. Last quarter, a lab result differed by 0.28% from field XRF. We re-sampled, re-ran fire assay, and adjusted pricing transparently. The buyer appreciated the correction it built trust faster than perfect numbers would have.”
