Can you introduce us to Alex Stewart International?

Alex Stewart International has been present in Argentina since 1999, beginning with a small workshop in Mendoza. Over time, we have expanded and added new services. Initially, we had a preparation room, and only ICP analysis was available. The company now has a total of 215 employees, and we are the only geochemical and environmental laboratory in Argentina that handles the entire process domestically, without outsourcing samples abroad.

Our headquarters are in Mendoza, where we handle all geochemical and environmental processes. We also have a preparation room and environmental analysis facilities in Jujuy, and we analyze lithium samples as well. We have laboratories in Perito Moreno, which specialize in gold and silver analysis, and in Puerto San Julián, where we prepare samples and send them for analysis in Perito or Mendoza. We are well-positioned within the Alex Stewart International group, serving both local and international clients.

We became the first laboratory in the world to achieve certification to the ISO 17025 standard for lithium analysis in 2008. This certification positioned us as a strong leader in Argentina in lithium analysis, covering both brine and lithium carbonate and chloride. We have maintained our leadership by supporting the industry with cutting-edge technology for lithium analysis. Our laboratory plays a key role in the development of the lithium industry in Argentina, which has seen increasing demand over the years.

What trends have you observed in the demand for geochemical services in the mining sector?

A few years ago, the focus was on lithium brine analysis, followed by a surge in gold analysis. Currently, the trend is shifting towards copper, especially in San Juan, where we have worked with several companies. Mendoza is also experiencing a surge in mining activity, and Santa Cruz remains a major mining powerhouse, with five active mines. Our ability to provide quick turnaround times for sample analysis is crucial, especially in exploration. For instance, we can report results within 48 to 72 hours, which is essential for decision-making in exploration projects.

What have been the most significant technological advancements in the laboratory sector?

We now utilize advanced equipment, including ICP, atomic absorption spectrophotometers, and X-ray fluorescence (XRF), for more precise readings. We also incorporated eco-friendly technology, such as eco-X and RX, for improved analysis. These upgrades enable us to handle specialized analysis requests, particularly for clients who require precise data for concentrates. Furthermore, we have placed a strong emphasis on training our analysts to ensure they can work effectively with the latest technology and adhere to strict industry standards.

How do you collaborate with other labs in the global Alex Stewart International network?

As part of Alex Stewart International, we maintain regular communication and collaboration with other laboratories in the network, including those in Chile, Peru, and Bolivia. While our primary focus is on geochemistry and environmental analysis, we also exchange information and technology with laboratories in other regions as needed. For example, we work closely with the labs in Chile and Peru, which have been operational for longer than we have, to share best practices and technological advancements. Additionally, we participate in annual inter-laboratory proficiency testing to ensure that our results meet the highest standards of quality.

How do quality certifications back your services?

Quality is a cornerstone of our operations. We hold certifications such as ISO 9001, ISO 17025, and ISO 14001, which are crucial in maintaining the credibility of our results. Our quality management team ensures that all procedures are strictly followed, and our analysts receive ongoing training to stay aligned with industry standards. By participating in inter-laboratory testing and maintaining these certifications, we ensure that our results are reliable. This is a key reason why we have consistently been ranked among the top five laboratories globally.

What are your plans for Alex Stewart Argentina in the coming year?

In the following year, we plan to establish a new branch in San Juan, which is becoming increasingly important for copper exploration and development. This will allow us to expand our services further in the region and better serve local mining companies. Argentina’s mining sector shows great potential, and we believe that with the right investment and government support, the industry will continue to thrive.
