on-lake construction

During the quarter SO4 completed the Stage 2 pond network, comprising of 275ha of evaporation pond area and 35km of brine extraction trenches, taking the total pond network size to 400ha. Stage 2 pond construction included the installation of 12,000 sheet piles and 200,000 cubic metres of earthworks to form the walls of the ponds, as well as 20 kilometres of pipework to move the brine from the trenches to the ponds.

Stage 3 pond construction is scheduled to commence in Q4 2020, with harvest salt availability aligning with process plant ramp up.

on-lake operations

Potassium grades across the pond network continue to follow the system curve and align with modelled outcomes. The Stage 1 pond system is producing salts from all five harvest cells during the quarter. The Stage 2 pond system is commissioned and is precipitating harvest salts.

To operate the brine abstraction trench network and evaporation pond system, a Brine Transport System (BTS) has been installed. Work on the BTS continued throughout the quarter.

The BTS provides flexibility to pump brine from across the different areas of the trench network and discharge into the various Halite ponds. Brine is drawn from four sumps strategically located across the lake, connected with pumps and pipes to individual cells across the pond network.

Process Plant construction

At the process plant site, ground clearing and bulk civil earthworks were completed during the quarter. This work included pad preparation for construction of the process plant, power plant, warehouse, workshop, administration and site village, as well as construction of the raw water pond, runoff settlement ponds and site access roads. Concrete foundations for the process plant and power station have commenced.

Procurement activities accelerated during the quarter with a number of major plant components ordered including the centrifuges, attritioners, flotation cells, sizing screens, thickeners, rotary drier, impact crusher, lump breakers and conveyer belts. Associated components including supporting steelwork, motor control centres, switchrooms, transformers, low-voltage and high-voltage cable have also been ordered. In combination these components make-up a material portion of the plant construction capex.

The Company is currently finalising the Engineering Procurement Construction Management (EPCM) and Engineering Procurement Construction (EPC) contracts with GR Engineering Servies (GRES), who are operating on site under an early services arrangement.

During the quarter GRES and Wood Group continued to develop the Process Plant design.

lake way village completed

Following the period-end construction and installation of the permanent infrastructure for the 100 person Lake Way village was completed, with workers moving in and first meal served on 24 April 2020. Completion of the on site village has reduced the daily travel time for workers by 90 minutes between the temporary accommodation and the processing plant site, further de-risking the Project and improving quality of life for the workforce. Work continues on the 200 person construction village designed to house workers during peak construction in the second half of the year.

LAKE WAY PALEOCHANNEL

During the quarter SO4 commenced drilling on the Lake Way paleochannel. The initial scope of work includes drilling at nine (9) pad locations along the Eastern side of the lake.

Installation of the first brine extraction bore was successfully completed in April with strong airlift flows observed.

In addition to the drilling on the Lake Way paleochannel, the Company also completed drilling at West Creek where fresh water supplies for the processing plant and potable water for the village will be sourced.

Water has been extracted from the West Creek area since the 1980's. SO4 secured a groundwater abstraction licence for 0.7GL/ year covering the existing borefield area in mid 2019. During the quarter SO4 drilled a total of seven (7) production bores and two (2) monitoring bores.

Offtake

During the quarter SO4 signed another binding term-sheet for the sale of 4kt per annum of SOP with Mitsui & Co. (Asia Pacific). The agreement has a five year term and is for the sale of premium quality water soluble SOP into select countries in Asia.

The Company has now secured binding term sheets for 224kt per annum of the 245kt per annum Lake Way production, with the remaining tonnes expected to be sold into local and spot markets.

Approvals

SO4 has continued to advancefinal permitting required to support full-scale operations. Work to date has not identified any social or environmental factors that could constitute fatal flaws or insurmountable obstacles to gaining necessary statutory approvals. The final outstanding approvals for the Lake Way Project are currently being progressed on schedule.

The EPA has determined that the full project scope requires formal assessment with no public review. As part of this assessment the EPA requires an Environmental Review Document to be prepared and submitted.

The seasonal rainfall received at Lake Way in early 2020 created conditions on site to allow meaningful additional environmental studies to be commenced. These surveys will support the Environmental Review Document and include:

· Flora survey. The survey involved targeted searches for priority species, soil profiling around Tecticornia, vegetation health monitoring of existing quadrats and installation of additional vegetation health quadrats.

· Fauna survey.

· Stygofauna survey of bores within the SO4 Lake Way production area.

· Shorebird assessment of Lake Way.

· Short range invertebrate assessment.

In addition to these surveys a number of studies have been continued and/or commenced to support the EPA submission which include:

· Visual impact assessment of the full scale operation.

· Ground water modelling optimisation to include all factors from the proposed paleo channel bores.

· Flood study modelling optimisation. The flood model has been improved as additional knowledge has been gained into the behaviour of lake surface water movement based on the recent rain events.

· Vadoze zone modelling.

· Salt dissipation study.

The studies and surveys will be completed shortly for submission of the ERD in the coming weeks.

The Company has continued to obtain Ministerial consents to use the land under section 18 of the Aboriginal Heritage Act 1972, for additional development as needed to meet ongoing project requirements with a number of applications being approved, including for the paleochannel bore works that have commenced.

In respect of the processing plant and village construction, the Company has received:

· Mining Proposal approval from the Department of Mines, Industry Regulation and Safety (DMIRS) for the construction of the processing plant and village.

· Project Management Plan approval from the Department of Mines, Industry Regulation and Safety (DMIRS) for the construction of the processing plant and village.

· Works Approval from the Department of Water and Environment Regulation (DWER) for the construction of the processing plant and a sewage treatment plant to support the village.

In respect of the initial paleochannel bores, project approvals for the construction of bores to obtain brine from the paleo channel were received from the Department of Mines, Industry Regulation and Safety (DMIRS) to enable this work to commence.

SO4 has obtained the necessary water licences to extract process water from the West Creek borefield and for brine extraction from the lake. Once the studies described above have been completed the final brine extraction licences will be sought.

exploration at lake marmion & lake Ballard

The Company is currently progressing resource development work at both Lake Marmion and Lake Ballard as part of a strategic review to prioritise which of SO4's lakes would be next development priority. During the quarter a passive seismic geophysical survey at both Lake Marmion and Lake Ballard were completed.

At Lake Marmion the results will be merged with the data from the 2019 survey to provide a comprehensive picture of the depth and width of the paelochannels beneath the lake surface. Laboratory analysis of the brine samples taken in the December 2019 quarter are ongoing.

At Lake Ballard, the survey was undertaken to further improve on the results of the 2018 gravity survey.

covid-19 business update

SO4 has responded with changes to its operations as Government advice regarding Covid-19 has evolved in order to minimise potential impacts. Specifically, interstate workers have elected to transit home while non critical movement to and from site has been minimised. All interaction with the local Wiluna community has ceased. Use of the Wiluna airport for travel to/from site has not been impacted and this airport continues to support the SO4 business. These changes to operations in response to Covid-19 are not currently expected to have an impact on the project schedule.

The Company has received no information from suppliers to suggest material delays to any items ordered for the process plant and non-process infrastructure.

As part of the Company's response to Covid-19, SO4 has also implemented a number of efficiencies and cost saving measures to ensure the ongoing success of the Project. These include a temporary 40% reduction to Director fees, executive and management salaries (including the Managing Director) and a 20% reduction to employees and contractors, to be monitored on a monthly basis effective April 2020.

Project Funding

Institutional Placement

In April 2020, the Company announced it had received binding commitments to place 58.8 million new ordinary shares at A$0.34 each to raise gross proceeds of A$20m. The shares were placed to existing and new institutional investors, confirming ongoing support for SO4 and the Lake Way project.

As part of the placement SO4 Directors and management subscribed for a total of 3.5 million shares. This includes 2,250,000 shares by Chairman, Mr Ian Middlemas and 505,883 shares by Managing Director and CEO, Mr Tony Swiericzuk, that they intend to subscribe for subject to shareholder approval.

The Placement funds will be used primarily on Lake Way Project development, including Process Plant procurement and construction and ongoing operation of Stage 1 & 2 Evaporation Ponds. The funds will enable SO4 to continue to deliver the Lake Way Project to achieve first production in Q1 2021.

Debt Financing

In August 2019, SO4 announced that it had mandated Taurus Funds Management (Taurus or the Lenders), to provide up to US$150m project financing for the Lake Way Project.

The Stage 1 Facility (Facility) provided initial access to funding for early construction works at the Lake Way Project and enabled completion of the BFS prior to drawdown of the main Project Development Facility (PDF). The Facility also funded civil works for the Stage 2 trenches and evaporation ponds, which will provide the initial harvest salt feed for plant commissioning.

To fund the ongoing construction of key infrastructure prior to drawdown of the PDF, the parties agreed to a US$15m extension to the Facility in December 2019. These funds were drawn down during the quarter and the extended Facility will be refinanced upon drawdown of the PDF.

Following completion of the BFS, SO4 has been working closely with Taurus to complete the documentation, derisk the project and satisfy the conditions precedent to the PDF in the near future. In addition to the PDF, the Company is assessing complimentary funding options to ensure that it is fully funded to complete construction in line with the Project schedule.
