Assaying Services

Assaying services:

If you are not sure how much value your material truly holds, we can determine the (precious) metal content of your materials. To learn more about this service and pricing, give us a call at (NEW) PHONE# COMING UP or send an email to .

We offer 3 types of assays for precious metals, for a brief description of each see below:

Fire assay:  

Available for Gold and Silver concentrations. Useful for higher (< 5 %) gold or silver contents. The material gets molten into a bar, a sample is drilled from the bar. The turnings from the sample get molten together with lead and silver on a so called cupel that absorbs the oxides formed from the less noble metals (such as Copper, Nickel, Zinc, etc.) and leaves a bead of gold and silver behind. After selective dissolution in acid the gold residue is dried and weighed on a high precision scale to determine the final gold / silver content.

Turnaround time is 2-3 business days.


Available for 32 elements, including copper, silver, gold, platinum, palladium & rhodium.
Depending on sample type and size, the material might be reduced in size through various mills and sample dividers. Following this procedure the sample is dissolved in acid and the solution is run through our ICP spectrometer. From the metal concentration in solution we can calculate the metal content of your sample.
This is a very precise method giving you a whole range of information about your sample and is very useful when you expect more than 1 valuable metal in your sample (e.g. you have a platinum-gold alloy).

Turnaround time is 3-4 business days.


Available for 15 elements, including copper, silver, gold, platinum, palladium & rhodium.
This is a very quick and accurate method (results available within 1 minute), provided the sample is homogeneous. The spectrometer sends X-rays into the sample exciting the material so it fluoresces back into the detector. From the fluorescence spectrum the instrument can calculate the metal concentrations in the sample. The drawback is that X-rays only penetrate the first few μm of the sample, so if a material is inhomogeneous (e.g. plated), the surface has to be filed/sanded so the core of the material is exposed, otherwise the reading is not accurate.

Results are available on the spot.
