We do ore testing and assays for professional prospecting, exploration, and geology work as well as mineral processing testing. Our assay lab performs fire assays for gold and silver ores, testing daily for precious metals in trace amounts and up to rich high grade ores and concentrates, continuously since 1954.

We test all types of ores and minerals. Tests include Spectrographic Analysis for most metals and fire assays for gold and silver ores, platinum minerals. X-Ray Spectrometer for metal ores, monazite, black sands and rare earth minerals. Fire assay, X-ray spectrometry, and Emission Spectrometer analysis provide fast, reliable assays to aid in ore exploration and discovery of precious metals.

Assay reports resolve questions about minerals and ores at reasonably low cost. We also test metal ores, concentrates, and black sand, for elements from Aluminum To Zirconium - including strategic metals, rare earths, and industrial ores such as Columbium, Tantalum, Copper, Zinc, Lead, Iron, Nickel, Tin, Titanium, Tungsten, and all other metals of commercial interest.

Our assay reports assist prospectors in evaluating ore grade minerals.
