About Bilex Minerals EA

About Bilex Minerals EA

Every important precious-metals decision begins with reliable information. Our laboratory provides independent Fire Assay and XRF testing that helps buyers, exporters, refiners, miners and investors understand exactly what they’re working with before moving forward.

What We Believe

Confidence begins with reliable evidence.

Reliable laboratory testing should provide confidence, not uncertainty.

We believe clients deserve results that are independent of the transaction, explained in plain language and supported by documented laboratory procedures.

Whether testing a single sample or supporting a larger commercial transaction, our goal remains the same: to provide reliable technical information that helps people make better decisions.

Who We Are

Independent by Design

Bilex Minerals EA is an independent gold testing laboratory established in 2019, with operations in Nairobi and Dar es Salaam. We work with buyers, exporters, mining companies, refiners, investors and international organisations that require independent information before making important commercial decisions.

Every sample is registered, handled with care, and tested using the method that best fits the client's question. We explain the findings clearly and keep the result separate from the sale or transaction. Every stage of the process is designed to provide reliable laboratory evidence while maintaining confidentiality, professionalism and technical independence.

Why Independence Matters

Valuable decisions deserve reliable information.

Buying or selling gold can involve significant financial risk. Appearance, markings, and paperwork may tell part of the story, but they cannot replace an independent laboratory result. Testing reduces uncertainty by giving both parties a technical reference based on the submitted sample, not on what anyone hopes the result will be.

Independent Results

The result is kept separate from the transaction.

Clearly Documented

The sample, method, and findings are recorded clearly.

Decision-Ready Information

You receive information you can use for your next decision.

Our Laboratory

Choosing the Right Testing Method

Every sample is different.

We recommend the most appropriate testing method based on the material being analysed, the level of accuracy required and the questions the client needs answered.

Fire Assay

A precise laboratory method for determining precious-metal content when valuation, settlement, or independent confirmation requires a dependable result.

XRF Analysis

A fast, non-destructive way to check the elemental composition of metallic samples during screening and routine verification.

Our Clients

Different goals. One shared need.

Whether working with first-time buyers or established international organisations, we apply the same laboratory standards, confidentiality and independent approach to every client.
