LSC Lithium Announces Pozuelos Project Phase 1 Drilling Completed

High Grade Lithium Drilled Across 10,787 hectares of the Salar

• Extensive lithium mineralization across the Salar peaking between 430 to 508 mg/l Li
• Consistent with previous short term average pump test results between 545 to 602 mg/l Li
• Excellent Relative Brine Release Capacity values peaking at 16.33%
• Further pumping and hydrogeological studies have commenced
• NI 43-101 Mineral Resource report planned for issue in Q4 2017

TORONTO, Nov. 13, 2017 /CNW/ - LSC Lithium Corporation ("LSC" or together with its subsidiaries, the "Company") (TSXV:LSC) is pleased to announce the completion of its Phase-1 15 hole drill program on its 99% controlled Salar de Pozuelos, Salta Province. The program was designed to evaluate the lithology and brine chemistry across the full extent of the salar to depths of up to 200m. The results of the program indicate the presence of extensive lithium mineralization across the entire salar which covers 10,787 hectares and is 99% controlled by the Company (See Map 1).

The assay results show that the salar has excellent brine chemistry, Relative Brine Release Capacity qualities and the brine values down-hole are consistent with the surface sampling results obtained previously¹. These results are also consistent with high grade lithium results returned from previously announced short and long-term pumping well test results². It is anticipated that LSC will release a NI-43 101 resource report in December based on work completed to date.

PUMP TEST RESULTS²

• W1-35 Short-term stress test: consistent Li assays averaging 602 mg/l Li and Mg:Li ratio of 4:1
• W2-90 Short-term stress test: consistent Li assays averaging 545 mg/I Li and Mg:Li ratio of 5:1
• W1-35 30-day test: averaged 591 mg/l Li and a constant Mg:Li ratio of 4:1
• W2-90 15-day test: averaged 548 mg/l Li and a Mg:Li ratio of 5:1

The Phase 1 exploration drilling program, which included 11 out of 15 planned holes on Salar de Pozuelos, has been completed and the balance of the assay results for brine packer sampling have been received (See Table 1). Three holes were cancelled due to ground conditions preventing access.

LSC's President & Chief Executive Officer, Ian Stalker, stated, "the Company has ramped up its efforts on the ground and is moving positively on the Pozuelos, Salinas Grande and Rio Grande Projects, as we push to complete three NI 43-101 compliant resource statements by late this year, early next year.

These latest results from Pozuelos have confirmed the Company's expectations in terms of the presence of wide spread, high grade mineralization across the Pozuelos salar. These results, which are supported by high grade well pump test results acquired earlier in the year, maintain the schedule for the delivery of the Pozuelos NI 43-101 Mineral Resource report, planned for the end of the year.  We are pleased with these results as we drive towards planned pre-feasibility studies in 2018. We hope to be able to start preliminary testing of these brines using Enirgi Group Corporation's direct extraction technology in late 2017, early 2018."

This work demonstrates the widespread nature of lithium mineralization present throughout this large land holding measuring 10,787 hectares.

LSC has now mobilized contractors to conduct a five hole pumping well test program and hydrogeological studies to assess pumping conditions in various parts of the Salar de Pozuelos and assess boundary conditions around the salar. This work program is anticipated to be completed by the end of November. Drill hole locations are noted in Table 1.

The final brine sample assay data (Table 2) and Relative Brine Release Capacity data (RBRC) (Table 3) have been received for several diamond drill holes at Pozuelos. Brine samples are recovered from the diamond holes using a packer system to isolate specific levels in the holes and assayed at Alex Stewart Assayers in Jujuy, Argentina. LSC previously released results for selected holes and sample intervals in a press release dated September 6, 2017. The new assay results are primarily for holes on the periphery of the salar. Assay results are consistent with the surface sample results from historical sampling³ and are summarized in Table 2.

Core samples for RBRC tests to determine Specific Yield, a measure of effective porosity, were taken from selected drill holes representing all lithologies and all depths of the holes drilled. Samples are shipped to Daniel B. Stephens & Associates Inc. ("DBSA") in Albuquerque, New Mexico for analysis. DBSA has developed a proprietary method to test effective porosity of core samples from salars that has been widely adopted by companies exploring for lithium brines. Details of the method are described in a paper by Stormont et. al. (2011)⁴.  Results for RBRC samples are detailed in Table 3 with one hole – SP-2017-13 results pending. The results show high RBRC values in the upper halite zones and productive zones in the deeper lying clastic zones. Pumping tests to develop additional hydraulic data are planned to commence as soon as a planned series of 5 pumping wells is completed.

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 by courier. 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 by courier to the assay laboratory.

RBRC samples were cut to length using a hack saw, bubble wrapped for protection and then placed in PVC tubes which were sealed with packaging tape. The samples were labelled and the labels wrapped in clear tape. Samples remained in the custody of the site geologist until shipped. Brine (20 L) from each of the holes from which the samples were collected was also shipped to 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.
