COMPLETION OF STAGE 2 ON-LAKE CONSTRUCTION

Salt Lake Potash Limited (SO4 or the Company) is pleased to announce the completion of construction of the Stage 2 evaporation ponds and trench network at its Lake Way SOP Project in Wiluna, Western Australia. This is a significant construction milestone and represents a further significant de-risking of the project. Construction progress continues to track in-line with the project schedule.

HIGHLIGHTS

§ The Company has now completed construction of 400ha of evaporation ponds and 35km of brine abstraction trenches.

§ Stage 2 includes 275ha of brine evaporation ponds which will provide feed salts to the process plant in 2021.

§ Focus has now shifted to construction of the process plant as well as other non-process infrastructure, where ground clearing and early stage civil activity has commenced.

§ The Project remains on-track to commence plant commissioning in December 2020, with first SOP sales in the March'21 quarter.

TONY SWIERICZUK, Chief Executive Officer

"The rapid delivery of the Lake Way SOP Project continues. Completion of the Stage 2 ponds, ahead of schedule and on budget, means the Company now has the infrastructure in place to supply harvest salts to the process plant in 2021. As these key milestones are completed the project continues to be significantly de-risked with expected first SOP production now just 10 months away"

sTAGE 2 COMPLETED & cOMMISSIONED

The Stage 2 pond network, comprising of 275ha of evaporation pond area and 35km of brine extraction trenches has been completed and is being commissioned. The commissioning process has seen in excess of 600ML of brine pumped into the Stage 2 ponds.

The completed Stage 1 & 2 ponds now span 400ha. In addition to the ponds, 35km of trenches have now been completed. The draining of high-grade (25kg/m3 SOP) brine from the Williamson Pit is also nearing completion.

Following completion of Stage 2, the construction team has shifted focus to the process plant and village where clearing and early civil work has commenced.

project remains on schedule and budget

January and February 2020 has seen various inclement weather events at Lake Way, which are typical for this time of the year. These events have not materially impacted our construction activities or project timeline, and our ponds are operating in accordance with design.

SO4 is using a staged approach to pond construction that aligns with the process plant ramp-up schedule and steady-state production requirements, enabling some initial capital expenditure to be deferred for a period of up to 12 months. Stage 3 on-lake work expected to commence in Q4'20.

As part of financing ongoing operations the Company has drawn down US$45m from the Taurus Stage 1 facility, ahead of expected finalisation of Project funding in the coming months.

Vesting of Performance Rights

Following completion of the Stage 2 evaporation ponds and brine extraction trenches, the Board has resolved that the relevant trench and pond milestone has been satisfied and approximately 4.2m performance rights have vested.
