LSC Lithium Announces Initial Exploration Results and Exploration Target on Salar de pozuelos Project in Northern Argentina

Lithium Brine Grades Consistently 500 to 600 mg/L Lithium down to 180 m

Exploration Target of 860,000 to 1,030,000 tonnes LCE at Salar de Pozuleos

TORONTO, April 10, 2017 /CNW/ - LSC Lithium Corporation (the "Company" or "LSC") (TSXV: LSC) is pleased to announce the first results from its current exploration program on the salar de Pozuelos property in Salta province, Argentina (the "Property"). LSC previously announced its pending acquisition of the Property by way of the exercise of an option to acquire 100% of the issued and outstanding shares of LitheA Inc. ("LitheA") from BMC Global Limited ("BMC").  The completion of the acquisition is subject to TSX Venture Exchange ("TSX-V") approval.

LSC considers the Property to be one of the most important undeveloped lithium brine projects in Argentina with the potential to be a significant lithium producer should the project successfully advance to a feasibility study level.

LSC has undertaken a program of diamond drilling, brine sampling, porosity testing and pumping tests on the salar over the past two months. Two pumping wells have been constructed to 45 m and 95 m depth and a deep diamond drill hole ("DDH") to 322.7 m has been drilled. In addition, piezometric wells have been drilled to depths of either 35 m or 90 m at distances of 5 m, 20 m and 50 m from the pumping wells to develop data on well performance.

Drill core from the piezometric wells and the deep diamond hole has been photographed, logged for lithology, and selected intervals sampled for Relative Brine Release Capacity (RBRC) tests at Daniel B. Stephens & Associates (DBSA) in Albuquerque, New Mexico for analysis.  DBSA are independent of LSC and Enirgi Group Corporation ("Enirgi Group"). The pumping and piezometric wells were developed, gravel packed and screened. The pumping wells were finished at 10" diameter while the piezometric wells were finished at 2" diameter.

Drill core data shows the salar is composed of highly fractured to moderately fractured halite down to approximately 35 m. Halite progressively becomes more massive to approximately 90 m depth, where the lithology transitions to a mix of clay and halite to a depth of approximately 170 m. A sand zone extends approximately 30 m to approximately 200 m depth, which then transitions to clay to the end of hole at 322.7 m in basement rock.

Table 1 summarizes the drilling completed by LSC to date.

Core samples for RBRC tests to determine Specific Yield (Sy), a measure of effective porosity, were taken from selected drill holes representing all lithologies and all depths of the holes drilled to date. Samples were shipped to DBSA in Albuquerque, New Mexico for analysis. Check samples were shipped to Core Laboratories Inc. ("Core Labs") in Houston, Texas, which is independent of LSC and Enirgi Group.  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 Stormont1 et. al. (2011).  Core Labs uses a modified version of the DBSA method.  Results from the tests received to date from DBSA are summarized in Table 2. Check sample results for RBRC samples are expected to be received the week of April 15, 2017.

Brine samples were recovered from the selected piezometric wells and the deep diamond drill hole using a packer system to isolate specific levels in the holes. The results available to date show consistent lithium brine grades down hole, as detailed in Table 3. The assays show the brine has excellent chemistry. Assays for deeper intervals from DDH-400 past 182 m have not yet been received.

Short-term pumping tests on well W1-35 were run to stress the well and develop data on the hydraulic properties of the upper 35 m of the salar. The tests were run at pump rates of 22 m3/hr to 36 m3/hr over a 6-hour period. The maximum drawdown was 20.77 m. After the pump was shut down, the well fully recovered in 10 minutes. Minimal drawdown (<5 cm) was observed at all of the piezometric wells. Brine samples were taken at periodic intervals throughout the test. The results showed consistent Li assays throughout the duration of the test. The results of the sample assays from the short duration pump test are detailed in Table 4. A short-term stress test of the 90 m pumping well (W2-90) is planned for completion the week of April 9, 2017.

LSC's planned exploration activities on the Property over the next two months include long term pumping tests for both the 35 m and 90 m pumping wells, seismic work and additional diamond drilling and pumping wells to test the full extent and depth of the salar.  It is estimated that these activities will cost approximately US$500,000.  LSC has funds on hand to pay for this program.

Based on the results of the current exploration work to date, and work completed by LitheA, LSC has developed an exploration target for the Property. The exploration target is based on a salar surface of 8,000 ha, a depth of 35 m for the upper halite zone, 55 m for the middle halite zone, and a depth of 30 m for the lower clastic zone, an average lithium brine grade ranging from 500 mg/L to 600 mg/L and average porosities of 3.1% for the initial 35 m, 1.7% for the interval between 35 m and 90 m and 6.8% for the lower clastic zone.  These ranges are conceptual in nature as further drilling and pumping tests will be required to validate the geological assumptions used, and further drilling may challenge these assumptions. There has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.  The exploration target is summarized in Table 5.

The Property is a major strategic acquisition for LSC as it is a large, high quality Salar located in close proximity to Enirgi Group's planned future regional processing facility at Salar del Rincón. LSC and Enirgi Group are strategically cooperating on lithium development in Northern Argentina pursuant to a Relationship Agreement whereby, among other things, the parties will examine the most economic solution to process LSC's brines which may include supplying LSC's brines for processing at Enirgi Group's planned facility. LSC expects to be able to begin shipping brine from the Property for testing at Enirgi Group's demonstration plant on the Salar del Rincón, following its anticipated commissioning, in the second half of this year. The map featured below shows the proximity of the Property to Enirgi Group's Salar del Rincón Project approximately 80 kilometers away.

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 Mendoza, 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.

LSC has a well-developed QA/QC program. Brine assays are undertaken at Alex Stewart Argentina ("ASA") S.A. in Menodoza, Argentina. ASA is independent of LSC and Enirgi Group and has significant experience in assaying lithium brines and is certified to ISO17025 standards. Brine assays are undertaken using the methods shown in Table 5.
