We are a development stage company focused on becoming a vertically integrated global leader and supplier of specialty boron and advanced boron derivative materials whose mission is to enable decarbonization, increase food security, and ensure domestic supply of critical materials. Our business strategy and objectives are to develop capabilities ranging from upstream extraction and product sales of boric acid, lithium carbonate and potentially other calcium co-products, to downstream boron advanced material processing and development. Our vision is to safely process boric acid and lithium carbonate through sustainable best practices.

In 2022, our facility was designated as Critical Infrastructure by the U.S. Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency. We believe the Project represents one of the most compelling domestic critical material projects in the United States as a strategically located operation that targets stable long-term demand, with a defined pathway to production and a low-cost, high margin and pr
