Forward looking statements

Forward Looking StatementsThis presentation contains forward-looking statements about Rincon Ltd. (“Rincon” or the “Company”) and its lithium project at the Salar del Rincon (“RinconProject”). Forward looking statements are statements that are not historical facts and are based on certain assumptions relating, but not limited to: resourceand reserve estimates, anticipated mining and processing methods for the Rincon Project, anticipated lithium recoveries, production and plant capacity rates,lithium grades, estimated capital costs, operating cash costs and total production costs, construction and supply of the necessary energy required, plannedadditional processing work and permitting, the timing for construction of phases of the commercial, type of lithium end product, and timing and availability offuture funding. While the Company considers these assumptions to be reasonable, based on information currently available, they may prove to be incorrect.The forward-looking statements in this presentation are subject to various risks, uncertainties and other factors that could cause the Company’s actual results orachievements to differ materially from those expressed in or implied by forward looking statements. These risks, uncertainties and other factors include,without limitation, risks related to uncertainty in the demand for lithium and pricing assumptions; uncertainties related to raising sufficient financing to fund theproject in a timely manner and on acceptable terms; changes in planned work resulting from logistical, technical or other factors; the possibility that results ofwork will not fulfill expectations and realize the perceived potential of the Company’s properties; uncertainties involved in the estimation of lithium reservesand resources; the possibility that required permits may not be obtained on a timely manner or at all; the possibility that capital and operating costs may behigher than currently estimated and may preclude commercial development or render operations uneconomic; the possibility that the estimated recovery ratesmay not be achieved; risks related to the deployment of a new lithium processing technology; risk of accidents, equipment breakdowns and labor disputes orother unanticipated difficulties or interruptions; the possibility of cost overruns or unanticipated expenses in the work program; and risks related to projectedproject economics, recovery rates, and estimated NPV and anticipated IRR and other factors.

These factors may cause the actual results of Rincon to differ materially from those discussed in the forward-looking statements and there can be no assurancethat the actual results or developments anticipated by management will be realized or, even if substantially realized, that they will have the expected results onRincon. Undue importance should not be placed on forward-looking information nor should reliance be placed upon this information. Rincon makes norepresentation or warranty, express or implied, as to or endorsement of the accuracy or completeness of any information, statements or representationscontained in this presentation. As a private company, Rincon is under no obligation and does not undertake to update this information at any particular time.

See appendix for footnotes and additional information

Appendix Resource & Reserve reference

Table 1 – Mineral Resource Estimate, Recoverable Lithium as Metal, effective September 2, 2018

(1) Average specific yield is approximated by the weighted average of individual lithologic specific yield estimates for each stratigraphic unit. Each estimate of specific yield is based on

physical testing of representative core samples, short-term (e.g., 1 to 3 days) and/or long-term (30 days) brine extraction tests.

(2) Average thickness identified for entire stratigraphic unit, not redefined by depth boundaries of Measured, Indicated, or Inferred Resource.

(3) Assigned cut-off grade for the brine process is 200 mg/L.

(4) Total brine volume is not equivalent to the total extractable brine volume. Brine extraction via engineered production wells is a function of the hydraulic properties (e.g.,

conductivity, saturated thickness and continuity) of each stratigraphic unit within the brine resource areas as well as the overall water balance for the hydrogeologic basin. These

properties are simulated in a 3-dimensional numerical model which allows estimation of the extractable brine resource as declared in the Mineral Reserve Statement.

(5) LCE calculated as a multiple (5.34) of the estimated lithium as metal value.

(6) All mineral resources are inclusive of mineral reserves.

(7) Mr. Jerry Aiken, P.G., R-SME, is an associate of SRK. He is an independent “Qualified Person” for purposes of NI 43-101 and he supervised the preparation of and verified the

above Mineral Resource Estimate, including the underlying sampling, analytical, test and production data. Data was verified by, among other things, multiple site visits and data

audits.

(8) Mineral Resources which are not Mineral Reserves do not have a demonstrated economic viability as of the date of this Technical Report.

(9) Table entries are rounded to reflect the precision of the estimate and differences may occur due to this rounding.

Table 2 - Salar del Rincón Lithium Reserve Estimate, Effective Date September 2, 2018

(1) Estimated by 46% rejection rate of lithium mass during brine beneficiation, and subsequent 60% re-capture of re-infiltrated lithium in reject brine. 54%+(46% x 60%).

(2) Recovery estimate provided by Turnkey.

(3) In situ recovery factor estimated by drawdown calculated by the dynamic model. High transmissivity and bowl-shaped geometry are conducive to dewatering the unit.

(4) In situ recovery factor estimated by drawdown calculated by the dynamic model. Production from black sand units enhance drainage from overlying units.

(5) In situ recovery factor estimated according to Houston, 2011.

(6) In situ recovery factor estimated by analytical solution for wellfield using BS-Series aquifer parameters.

(7) Massive halite unit is defined entirely as an Inferred resource. Production potential from the unit is low, owing to its competent crystalline matrix and low permeability.

General

a) Assigned cutoff grade of 200 mg/L Li.

b) The cut-off grade at which Li extraction is no longer economic is varied based on a number of recovery and cost factors including the geologic formation from which the extraction

is occurring, the concentration of deleterious elements such as magnesium in the raw brine, raw brine pumping/processing capacity in the lithium plant and the lithium pricing

assumptions.

c) Mr. Tyler Cluff, P.G., is an employee of Piteau Associates. He is an independent “Qualified Person” for purposes of NI 43-101 and he supervised the preparation of and verified the

above Mineral Reserve figures, including the underlying sampling, analytical, test, and production data. Data was verified by among other things, a site visit.

d) Table entries are rounded to reflect the precision of the estimate and differences may occur due to this rounding.
