LSC Lithium Announces Progress on Its Pozuelos-Pastos Grandes Preliminary Economic Assessment Project

Aug 7, 2018

TORONTO, Aug. 07, 2018 (GLOBE NEWSWIRE) -- LSC Lithium Corporation (“LSC” or together with its subsidiaries, the “Company”) (TSXV:LSC) is pleased to announce encouraging progress on exploration and pump testing for its Pozuelos-Pastos Project (“PPG”). The Company has engaged the internationally recognised engineering consultancy company GHD Limited to undertake a preliminary economic assessment (“PEA”) on this combined PPG Project due to be completed by end of Q4 2018.



  • Three of the six planned pump tests have been completed with grades of up to 731mg/l from well SP-2017-10W 1 .
  • 14.394 line km of seismic data acquired along one survey line.
  • Construction of access roads and drilling platforms underway for exploration drilling in the north east of the salar.
  • Start of deep exploration drill hole PZ-18-01 in the centre of the salar, currently 315.03m.
  • Construction of the Pozuelos exploration camp to be completed in August 2018. Camp will be converted to administration offices during operations.
  • Updated Mineral Resource expected in Q4 2018.

Pastos Grandes

  • Significant progress achieved with drill hole PG-18-01 currently 541.4m. Average downhole grade of 491mg/l from surface to 474.62m depth.
  • 15.372 line km of seismic data acquired along six survey lines.
  • Maiden Mineral Resource Estimate expected end of Q3 2018.

PPG Project

  • Environmental Baseline Studies completed at both salars.
  • Ongoing PEA work for completion in Q4 2018.

LSC’s President and CEO Ian Stalker, noted, “The PPG Project is now in full data acquisition phase to support the PEA and the subsequent Prefeasibility Study. Furthermore, the significant progress on the environmental baseline studies will ensure that we can submit our Environmental Impact Statement to the Regulator before year end. We remain on-track for a resource announcement at Pastos Grandes at end of Q3 2018. It is also important to note the added future operational flexibility (blending, pumping options, etc.) and increased scalability of production volumes this combined salar approach gives us at Pastos Grandes and Pozuelos, as well as being much more environmentally appropriate in having one, instead of two, footprints for an operational plant.”


Pump Test Progress

Pump tests at Pozuelos are proceeding as planned with three of the planned six completed. Table 1 below summarises the exploration well results.

SP-2017-14W 3417966 7264929 Clastics 9 51 48 358 Constant 19.5 22.41

Longer term 7-day pump tests are planned to confirm the aquifer yield and consistency of brine chemistry. Results from the pump test campaign at Pozuelos will be used in the development of a hydrological balance to support the Environmental Impact Assessment, which is planned to be submitted before the end of the year. Furthermore, pump test results will supply data for the hydrodynamic model, which is the precursor to the estimation of Mineral Reserves for the PFS, expected in Q3 2019.

Seismic Data

14.394 line km of seismic data was acquired in the southern area of the salar during June 2018 along one survey line. The results will be used in conjunction with previous seismic data and with the pump tests and exploration hole results to update the current Mineral Resource estimate, expected during Q4 2018.

Exploration Holes Progress

A civil works contractor has been commissioned to undertake the building of access roads and drilling platforms for the exploration holes in the north-east of the salar. Access from current roads along the north west section of the salar to the location of exploration holes PZ-18-02 and PZ-18-03 are progressing as planned and the location of PZ-18-02 has been reached. Construction of the drilling platform is to commence shortly, where after core drilling is to commence.

Progress with exploration hole PZ-18-01 is on track, with core samples being submitted to determine porosity values. Hole PZ-18-01 is currently at 315.03m below collar and progressing well.

Exploration Camp

In April 2018, LSC commenced the construction of a 40 person exploration camp at the Pozuelos salar. The camp will simplify future exploration logistics, support the construction and operation of pilot ponds and has been designed to be expanded for future mine operations. The camp is expected to be completed and occupied in August 2018.

Once the PPG Project has progressed from construction and production, it is intended that this camp will be expanded and utilized for mine administration offices and as an operational camp.


Seismic Data

The acquisition of 15.372 line km of seismic data was completed during May and June 2018. This data will be used to support the maiden Mineral Resource estimate expected at the end of Q3 2018.

Exploration Hole

Exploration hole PG-18-01 is currently at 541.4m below collar and progressing well. Intersected lithogies are a combination of evaporites and sediments, with brine intersected throughout the complete drill hole. Average assay results over the entirety of the drill hole is 491mg/l down to a depth of 474.62m below collar.

The results of this hole will be used in the Maiden Mineral Resource estimate at Pastos Grandes at the end of Q3 2018.


Completion of Environmental Baseline Studies

LSC’s environmental team has completed the biodiversity, soil, air, noise, water, archeological and social baseline studies at both Pozuelos and Pastos Grandes. These are important steps towards the completion of the Environmental Impact Statement, which is planned for submission in Q4 2018, after completion of hydrological balance model.

Kick-off of Preliminary Economic Assessment

In June 2018, LSC and its owner’s team representatives attended the kick-off meeting of the PEA, hosted by GHD in Santiago. The meeting was focussed on identifying means to optimise process recovery, operating costs, capital costs and implementation schedule.

To support this strategy, an initial lab test work was completed to study the evolution of Pozuelos´ brine chemistry and the results of this work were used to design and calibrate a modelling tool that enables LSC to obtain a Mass Balance and pre-analyze projections of different scenarios. This supports trade-off studies against the defined base case for the PEA. A second stage metallurgical test work program, including both laboratory benchscale work and the construction of pilot ponds at Pozuelos is being developed. This expected to launch in August 2018.
