SALT LAKE POTASH LIMITED
Initial Results Confirm Lake Way Potential
--------------------------------------------
Salt Lake Potash Limited (SLP or the Company) is pleased to
provide an update on the Company's Lake Way project since following
execution of an MOU with Blackham Resources Limited's (Blackham)
outlining the potential to incorporate Blackham's Mining Lease
tenure into the development of a Sulphate of Potash (SOP)
operation.
Highlights of work completed include:
Surface Sampling Program
Ø A preliminary surface sampling program on Blackham's tenements
confirms the Lake's average SOP grade of over 14kg/m(3) , making
Lake Way one of Australia's highest grade SOP brine sources.
Geotechnical Investigations
Ø An initial geological and geotechnical investigation by the
Company and Knight Piesold confirmed the availability of in-situ
clays amendable for on-lake evaporation pond construction. A total
of 24 auger holes were excavated across Blackham's tenements and
laboratory tested.
Surface Aquifer Exploration
Ø Review and modelling of the large volume of historical
exploration data for Lake Way confirms the likelihood of a large
hypersaline brine pool on both Blackham and SLP's tenements.
--
Ø The Company is in the process of mobilising a drill rig and an
amphibious excavator on the Lake to complete an initial surface
aquifer exploration program.
Ø The surface aquifer program will include the construction of
test pits and trenches for long-term pump testing.
Process Testwork
Ø The Company has commenced a range of process development
testwork including process pathway modelling by international
experts, a bulk sample evaporation trial and site-based evaporation
trial at Lake Way.
CEO Matt Syme said "These initial results are very pleasing and
support the Company's view that Lake Way is an ideal site for our
SOP Demonstration Plant and subsequent expansions. It appears to
have the best combination in Australia of scale, brine chemistry,
playa surface, shallow clays for pond construction, permitting
pathway and infrastructure access, which should result in
substantial time and cost advantages."
LAKE WAY
Lake Way is located in the Goldfields region of Western
Australia, less than 15km south of Wiluna. The surface area of the
Lake is over 270km(2) .
The Wiluna region is an historic mining precinct dating back to
the late 19th century. It has been a prolific nickel and gold
mining region and therefore has well developed, high quality
infrastructure in place.
The Goldfields Highway is a high quality sealed road permitted
to carry quad road trains and passes 2km from the Lake. The
Goldfields Gas Pipeline is adjacent to SLP's tenements, running
past the eastern side of the Lake.
SLP has entered an MOU with Blackham to investigate the
development of an SOP operation on Blackham's existing Mining
Leases at Lake Way including, initially, a 40-50,000tpa
Demonstration Plant (see announcement dated 12 March 2018).
Lake Way has some compelling advantages which make it
potentially an ideal site for an SOP operation, including:
Ø Substantial likely capital and operating savings from sharing
overheads and infrastructure with the Wiluna Gold Mine, including
the accommodation camp, flights, power, maintenance, infrastructure
and other costs.
Ø The site has an excellent freight solution, adjacent to the
Goldfields Highway, which is permitted for heavy haulage 4 trailer
road trains to the railhead at Leonora.
Ø A Demonstration Plant would likely be built on Blackham's
existing Mining Licences, already subject of a Native Title
Agreement.
Ø SLP would dewater the existing Williamson Pit on Lake Way,
prior to Blackham mining, planned for early 2019. The pit contains
an estimated 1.2GL of brine at the exceptional grade of 25kg/m(3)
of SOP. This brine is potentially the ideal starter feed for
evaporation ponds, having already evaporated from the normal Lake
Way brine grade, which averages over 14kg/m(3) (.)
Ø The high grade brines at Lake Way will result in lower capital
and operating costs due to lower extraction and evaporation
requirements.
Ø There would be substantial savings to both parties from
co-operating on exploration activities on each other's ground.
Ø The presence of clays in the upper levels of the lake which
should be amenable to low cost, on-lake evaporation pond
construction.
SLP will complete a Scoping Study for a potential SOP operation
at Lake Way, including a Demonstration Plant, by mid-2018, in time
to allow a decision on dewatering the Williamson Pit under the MOU.
There is substantial historical data available for Lake Way and,
along with the extensive, high quality technical work undertaken at
SLP's other lakes, which has substantial application at Lake Way, a
Scoping Study can be undertaken in a much shorter timeframe than
would normally be the case.
Surface Sampling Program
The Company has now completed initial surface sampling program
at Lake Way, substantially covering the Lake surface. A total of 23
pit samples have been collected encountering brine at a standing
water level generally less than 1 metre from surface.
The average brine chemistry of the samples was:

The brine chemistry at Lake Way is very consistent over the lake
surface. The SOP grade are amongst the highest achieved in
Australia to date.
Geotechnical Investigations
To gain an understanding of ground conditions for trenching and
pond construction, a preliminary geotechnical investigation program
was undertaken within the Blackham Mining Tenements, in conjunction
with leading international geotechnical consultants, Knight
Piesold.
A total of 24 hand auger boreholes were drilled to depths of up
to 3.2 metres, and the encountered soils were logged and
sampled.
Lake Way ground conditions consists of a thin surface layer of
evaporite sands, overlying sandy and silty clays. Firm clays were
encountered at 1m to 2m depth, generally increasing in strength
with depth, becoming hard from 2m to 3m. Shallow groundwater was
encountered on average 0.2m below the lake surface.
A testing program was undertaken at a NATA accredited
geotechnical laboratory, using specific test methods appropriate
for saline conditions, to characterise soils and assess preliminary
soil parameters.
Summary test results are presented below.

Erodibility characteristics were tested and an Emerson class
number of 6 was measured for all samples. This indicates
non-dispersive soils that are not prone to erosion when used to
form embankments.
Based on the preliminary geotechnical work to date, Knight
Piesold have concluded that:
- the in-situ clay materials can be expected to provide natural
low permeability layers to control seepage of on-lake ponds.
- the clays are suitable for embankment construction purposes,
with adequate moisture control and borrow pit dewatering.
- A key advantage of Lake Way is the presence of a drier clay
zone surrounding the Williamson Pit, which has the potential to
provide borrow materials and construction schedule benefits for the
upcoming pond construction programs.
Knight Piesold is now preparing an options study to evaluate
design concepts for large-scale pond systems and provide earthworks
quantities and costs. Seepage assessments and flood studies are
underway. In parallel, design work is being undertaken for a
dewatering pond to hold the Williamson Pit brine.
Surface Aquifer Characterisation
Lake Way and its surrounds have been the subject of a
substantial amount of historical exploration for gold, nickel,
uranium and other minerals, as well as for process water for mining
operations. A total of over 2,800 holes have been drilled in and
around the Lake previously, providing a very large database of
geotechnical information.
SLP have commenced compiling, digitising and interpreting the
historical exploration database to extract relevant data and
provide initial basement geometry for the Lake area, to assist
estimation of an initial JORC compliant resource.
The Company is also in the process of mobilising a small
track-mounted drill rig and an amphibious excavator to complete an
initial surface aquifer exploration program. This work will provide
critical data for the hydrogeological model for the surface aquifer
of the Lake, as well as geological and geotechnical information for
infrastructure design and construction.
The surface aquifer program will include the construction of
test pits and trenches for long-term pump testing.
The drill campaign is also intended to sterilise (for gold
exploration) sufficient areas for siting brine extraction trenches
and evaporation ponds.
Process Testwork
The Company has commenced a range of process development
testwork to provide and validate inputs to the Lake Way Scoping
Study production model. Naturally, this includes testing brines
from the Lake itself, as well as the super-concentrated brines from
the Williamson Pit.
The testwork aims to confirm the modelled brine evaporation
pathways firstly under laboratory simulated conditions and then
from a site-based trial of sufficient scale to test on-lake
evaporation conditions.
Initial brine evaporation modelling, conducted by
internationally renowned solar pond experts, Ad Infinitum,
indicates the salts produced at Lake Way will be comparable to
those produced at Lake Wells and therefore suitable for conversion
into SOP.
International laboratory and testing company, Bureau Veritas
(BV), has commenced a series of laboratory-scale brine evaporation
trials at their Perth facility, under simulated average Lake Way
climate conditions. The aim of the BV trials is to monitor the
chemical composition of the brine and salts produced through the
evaporation process to confirm:
-- Concentration thresholds in the brine chemistry which can be
used to maximise the recovery of potassium in the harvest salts and
minimise the quantity of dilutive salts fed to a process plant;
-- The quantity and composition of harvest salts which will for
the plant feed in commercial production; and
-- The potential for any internal evaporation pond recycle
streams that may improve harvest salt recovery.
Two tests - one for Williamson Pit brine and one for normal Lake
Way brine - are currently underway, each evaporating 150kg of brine
on a load cell to monitor evaporative loss. The temperature of the
brine and air flow across the brine surface is controlled by using
infra-red lamps and fans to simulate Lake Way average weather
conditions.
A Site Evaporation Trial (SET), as successfully operated at Lake
Wells previously, is under construction at Lake Way and will be
filled with first brine over the next week. The SET will gather
specific evaporation data on concentrated brines under actual
conditions, providing refinements to the commercial scale pond
modelling.
The Site Evaporation Trial is also designed to produce
sufficient harvest salt for confirmatory process testwork and
initial customer samples.
