Principal geochemical and environmental laboratories Alex Stewart Argentina are located in Mendoza, San Julian, Jujuy and Perito Moreno to provide world-class sample preparation and full analytical services to the mining industry in both Argentina and Latin America.
Geochemical analysis and sample preparation services are tailored to Argentina’s mining industry by acknowledging both senior and junior mining projects need for fast and accurate assay determinations. The laboratory combines both high tech instrumentation and classical wet geo-chemistry methods such as fire assay, micro-gravimetric, AA, ICP-OES, and regularly participates in certification programmes including Geostats and CANMET round robins.
Sample preparation is not restricted to our static Mendoza laboratory; we can overcome logistical complexities by preparing samples at mine sites. We have considerable experience in designing tailor made and mobile sample preparation facilities that can be equipped to meet specific requirements and that are transportable from mine project to mine project. Typical mobile preparation facilities would include drying oven jaw crushers, lab-technic grinders, riffles, sieves, shakers, dust extraction.
Environmental services are provided to many industries particularly mining exploration companies, water authorities, universities, councils and government organizations. Services range from analysis of sewage water, potable water, gas emissions, soils and hazardous waste.
