Our assay laboratory offers ore assay services, ore testing, and assays for mining exploration, prospecting, including radioactive minerals, rare earth geology work as well as mineral processing and testing. Our ore assay lab performs fire assays for gold and silver ores, testing daily for precious metals in trace amounts up to 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 metallic 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.
