Lithium Harvest (Sustainable Projects Group) ^{Filed, US Offering, NYSE: LIHV}

Sustainable Projects Group Inc. (“SPGX,” “we,” “us,” our” or the “Company”) is a pure-play lithium company focused on supplying high performance lithium compounds to the fast-growing electric vehicle (“EV”) and broader battery markets. We have developed a proprietary technology to extract lithium from oilfield wastewater, which we believe will enable us to manufacture lithium compounds quickly, at an attractive cost, and with a minimal environmental footprint, which we expect to provide us with a competitive advantage over other lithium manufacturers. We believe this competitive advantage will enable us to capitalize on the acceleration of vehicle electrification and renewable energy adoption. We plan to start construction of our first two lithium carbonate manufacturing facilities in North Dakota in the second half of 2024, which we anticipate will be capable of manufacturing up to a total of 2,800 metric tons of lithium carbonate, and we plan to begin manufacturing battery-grade lithium compounds at such facilities in the second half of 2025. No assurance can be given that we will be able to establish such facilities or begin manufacturing within this timeframe or at all.
