 “ppm” and % refer to million metric tons, thousand metric tons, parts per million, and percent by weight, respectively.
(5)Mineral Reserves are based on an iodine price of US$42,000 per metric ton and a price of US$820 per metric ton for potassium-sodium nitrates. Mineral Reserves are also based on economic viability as demonstrated in an after-tax discounted cashflow.
(6)Marco Fazzi, Freddy Ildefonso and Gino Slanzi are the QPs responsible for the Mineral Reserves.
(7)The QP is not aware of any environmental, permitting, legal, title, taxation, socioeconomic, marketing, political or other relevant factors that could materially affect the Mineral Reserve estimate that are not discussed in this TRS.
(8)Comparisons of values may not total due to rounding of numbers and the differences caused by use of averaging methods.

________________________________________________
(1)Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resource will be converted into Mineral Reserves upon the application of modifying factors.
(2)Mineral Resources are reported as in-situ and exclusive of Mineral Reserves, where the estimated Mineral Reserve without processing losses during the reported LoM was subtracted from the Mineral Resource inclusive of Mineral Reserves.
(3)Comparisons of values may not add due to rounding of numbers and the differences caused by use of averaging methods
(4)The units “Mt”, “ppm” and % refer to million metric tons, parts per million, and percent by weight, respectively.
(5)The Mineral Resource estimate considers a cut-off grade of 200 ppm for equivalent iodine, as well as caliche thickness ≥ 2.0 m
