Standard Lithium Appoints Dr. Andy Robinson As Chief Operating Officer

VANCOUVER, BC / April 25, 2017 / Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (SLL.V) (S5L.F) is pleased to announce the appointment of Dr. Andy Robinson as President and Chief Operating Officer of the Company. Dr. Robinson will take up his appointment effective immediately and will be directly responsible for rapidly accelerating the Company’s resource acquisition, assessment, and process development initiatives.

Dr. Robinson most recently served as Chief Operating Officer and board member for Pure Energy Minerals, where he was responsible for leading the first Inferred Resource assessment for a lithium brine deposit in North America, in accordance with 43-101 guidelines. During his tenure at that company, he was instrumental in developing innovative exploration, sampling and assessment techniques for lithium brine resources, and was responsible for developing a world-class lithium brine process engineering team. This team successfully developed and tested efficient and effective modern brine processing techniques that will help shape the way in which lithium products are extracted from brine in the future. Prior to joining Pure Energy in 2014, Andy held a series of senior technical and executive management roles with publicly listed companies in the energy, power and engineering sectors, and has been responsible for successfully taking projects from inception to production while developing sustained corporate growth. Andy is an experienced geoscientist with 20+ years of experience, a PhD in Geochemistry from the University of Bristol, UK, and has worked on a wide range of projects in the resource, power and energy sectors in Europe, Africa, and North and South America.

“The opportunity for me to join Standard Lithium is very exciting, and I strongly believe in their vision for using modern techniques to develop and process large-scale domestic lithium brine resources. We have an aggressive development schedule ahead of us as we look to rapidly move projects towards production, and my focus is to ensure that we have the best teams in place to execute our corporate strategy.”

Mr. Robert Mintak, CEO and Director of Standard Lithium, commented, “We are extremely pleased to have someone of Dr. Robinsons’ caliber join the team. Leveraging innovation is fundamentally important for us, having previously worked with Andy I know he will be an instant and valuable contributor to the Company.”
