• LSC now has a total inventory from three salars, Pastos Grandes, Pozuelos and Rio Grande, totalling 2,235,080 tonnes of LCE in the Measured and Indicated category and 2,994,500 tonnes of LCE in the Inferred Category¹

TORONTO, Nov. 06, 2018 - LSC Lithium Corporation (“LSC” or together with its subsidiaries, the “Company”) (TSXV:LSC) is pleased to announce the issue of its maiden Mineral Resource on its Pastos Grandes Salar and the filing today of the Technical Report titled “Technical Report on Pastos Grandes Lithium Project” dated October 25, 2018 with an effective date of October 19, 2018 (the “Technical Report”). This NI 43-101 Mineral Resource estimate includes 939,080 tonnes of lithium carbonate (Li₂C0₃) equivalent (“LCE”) in the Measured and Indicated category and 307,500 tonnes of LCE in the Inferred category (see Table 1).

The Company’s President and CEO Ian Stalker stated, “We are extremely pleased with this robust resource from our Pastos Grandes project which marks another milestone in the development of the PPG Project. With an updated resource on Pozuelos expected to be released this month, we anticipate that the larger combined lithium carbonate equivalent inventory and the blend of the chemistry from both the Pozuelos and Pastos Grandes salars will add to the upside of the PPG Project. It is also worth noting that the Pastos Grande resource remains open at depth.

LSC paid significant attention to the RBRC measurements in Pastos Grandes, recognizing the importance of this value to the ongoing PEA work and to the variability of this measurement seen across the Salar and is comfortable in the conservative approach to this number and the resulting resource estimate.”

LSC is currently completing an updated resource report for its Salar de Pozuelos property and is undertaking a PEA for the PPG Project based on a target production rate of 20,000 tpa lithium carbonate. The resource on Pastos Grandes and the updated resource on Pozuelos will be used to feed the lithium production system for the PPG Project. The current resource estimate on Pozuelos includes 1,296,000 tonnes of LCE in the Measured and Indicated Mineral Resource category and 497,000 tonnes in the Inferred Mineral Resource category².

The brine chemistry results for Pastos Grandes show a complimentary nature with the brine from the Pozuelos salar², which supports these projects being developed jointly (See Table 2).

Table 1 – Pastos Grandes Mineral Resource Estimate as at October 19, 2018

Notes:

1. Brine volumes are before application of Relative Brine Release Capacity (RBRC) factor.
2. RBRC value is the weighted average for the lithological unit within each resource category.
3. Resources have been classified in accordance with CIM mineral resource definitions, May 25, 2014 and the CIM Best Practice Guidelines for Estimation of Lithium Brine Resources and Reserves.
4. Resources have been estimated by Louis Fourie, P. Geo., Pr.Nat. Sci., under the direction of D. Hains, P. Geo.
5. The effective date of this mineral resource estimate is October 19, 2018.
6. Resources have been estimated using a cut-off grade of 100 mg/L lithium.
7. Mineral resources which are not Mineral Reserves do not have demonstrated economic value. There is no assurance that additional exploration will result in the conversion of Mineral Resources to Mineral Reserves.
8. Inferred Mineral Resources are considered as too speculative to have economic criteria applied to them. There is no assurance that additional exploration will result in the conversion of Inferred Mineral Resources to Indicated or Measured Mineral Resources.
9. A conversion factor of 5.323 has been used to convert Li metal to LCE and does not include any other chemical elements.
10. Totals for Measured and Indicated and Inferred Resources have been rounded.

Table 2 – Key Chemical Ratios

The brine chemistry is amenable to lithium carbonate production using conventional lithium brine processing technologies for brine concentration such as solar evaporation. A cut-off value of 100mg/l Li has been applied. The cut-off value is reasonable based on current and projected lithium prices, reasonably assumed lithium recovery factors and comparisons to other lithium exploration projects for which Measured and Indicated Resources have been estimated.

For further information regarding the key assumptions, parameters, and methods used to estimate the mineral resources and the exploration program conducted at Pastos Grandes, please see the Technical Report which has been filed today on SEDAR (www.sedar.com) and is also available on the Company website (www.lsclithium.com). Hains Engineering Company Limited and Hains Technology Associates, located in Toronto, Ontario, Canada, were engaged to prepare an independent Mineral Resource estimate for LSC’s Pastos Grandes salar and also to prepare the Technical Report in accordance with National Instrument 43-101 - Standards and Disclosures for Mineral Projects.

Sampling and QA/QC

Brine sampling for packer tests involved collection of brine from the sample interval in a 20-litre container, which was flushed with fresh brine several times prior to collection of the sample. Brine was poured into 1-litre sample bottles which had been previously flushed with fresh brine from the 20-litre container several times. Sample bottles were filled to the top to eliminate the inclusion of air and sealed with a leak proof lid. Samples were labelled and labels covered in clear tape to prevent erasure of sample information. All samples remained in the possession of the site geologist until delivery to Alex Stewart Laboratory in Jujuy, Argentina. Brine sampling for the pump stress test involved collection of samples from a valve attached to the pump outlet. Brine was allowed to flush and then fresh brine was used to wash the sample bottle several times before collecting the sample. Sample bottles were 1-litre in size and were filled to the top to prevent entrance of air. The samples were sealed with a leak proof lid, labelled and the label covered by clear tape. Samples remained in the possession of the site until delivery to the assay laboratory.

RBRC samples were cut to length using a hack saw, bubble wrapped for protection and then placed in PVC tubes sealed with packaging tape. The samples were labelled and the labels were wrapped in clear tape. Samples remained in the custody of the site geologist until shipped. Brine (20-litre) from each hole from which the samples were collected was also shipped to Daniel B. Stephens & Associates Inc. ("DBSA") as part of the sample test protocol. DBSA is independent of LSC.

LSC has a well-developed QA/QC program. Brine assays are undertaken at Alex Stewart Argentina (“ASA”) S.A. in Jujuy, Argentina. ASA is independent of LSC and has significant experience in assaying lithium brines and is certified to ISO17025 standards. Brine assays are undertaken using ICP, gravimetric, potentiometric and volumetric methods as detailed in a press release from LSC dated April 10, 2017. ASA runs internal duplicates at a rate of 1 in 20. LSC inserts blanks and standards in sample batches at a rate of 1 in 20. Standards are internal standards developed by LSC that have been independently certified by round robin testing. LSC uses distilled water as blanks.
