Our operations in Argentina are seasonally impacted by weather, including varying evaporation rates and amounts of rainfall during different seasons, which can be heavy at times. These changes impact the concentration in large evaporation ponds and can have an impact on the downstream processes to produce lithium carbonate and lithium chloride. Heavy rainfall can damage pond liners, lead to loss of product, and make the ponds generally difficult to maintain. Our operations team continuously measures pond concentrations and models how they will change based on operating decisions. Our processes use proprietary and traditional technologies to minimize the variation of concentrations at the inlet to our plants. There was an abnormally large rain event in both the first quarter of 2019 and during the last quarter of 2021. These resulted in reductions in lithium carbonate production of approximately 1,000 MT in 2019, and approximately 500 MT in 2021.
