SALT LAKE POTASH LIMITED
MOU With Blackham Resources For Potential Development Of Lake Way
--------------------------------------------------------------------
Salt Lake Potash (SLP) is pleased to announce that the Company
has entered a Memorandum of Understanding (MOU) with Blackham
Resources Limited (Blackham) to investigate the potential
development of a Sulphate of Potash (SOP) operation based at Lake
Way, near Wiluna.
SLP holds approximately 290km(2) of tenure over the Lake Way
Paleochannel, as part of the Goldfields Salt Lakes Project (GSLP).
Blackham is the owner of the Matilda-Wiluna Gold Operation and
holds approximately 64km(2) at the Northern End of the Lake. This
surrounds the former Williamson Pit, last mined in 2006 and now
filled with brine at an exceptional grade of 25kg/m(3) of SOP.
Under the MOU, SLP will acquire Blackham's brine rights and
Blackham will acquire gold rights to SLP's Lake Way holdings, with
each company retaining a royalty on their respective holdings. The
parties will also co-operate to exchange data and facilitate
activities on each other properties.
SLP will investigate the development of an SOP operation at Lake
Way, including initially a 40-50,000tpa Demonstration Plant. SLP
will sole fund the evaluation and development of any SOP operation
at Lake Way. Lake Way has some compelling advantages which make it
potentially an ideal site for an SOP operation, including:
-- Substantial capital and operating savings from sharing
overheads and infrastructure with the Wiluna Gold Mine, benefits
which both Companies would capture. This includes potentially the
accommodation camp, flights, power, maintenance, infrastructure and
other costs.
-- The site has an excellent freight solution, located 2km from
Goldfields Highway, which is permitted for heavy haulage 4 trailer
road trains to the railhead at Leonora. It is also adjacent to the
Goldfields Gas Pipeline.
-- A Demonstration Plant would likely be built on Blackham's
existing Mining Licences, already subject of a Native Title
Agreement.
-- SLP would dewater the existing Williamson Pit, 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 (Refer Appendix 1 for Williamson Pit brine samples details).
This brine is potentially the ideal starter feed for evaporation
ponds, having already evaporated from the normal Lake Way brine
grade, which averages around 14kg/m(3) (.)
-- The high grade brines at Lake Way will result in lower
capital and operating costs due to lower extraction and evaporation
requirements.
-- There would be substantial savings to both parties from
co-operating on activities on each other's ground.
-- Historical exploration and initial sampling indicate 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. There is
substantial historical data available for Lake Way and the
companies have already undertaken preliminary sampling in the
Blackham area. 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 reliably undertaken
in a much shorter timeframe than would normally be the case.
SLP CEO Matt Syme said "we are pleased to reach this agreement
with Blackham which could potentially bring very substantial
benefit to both companies, and adds significant value from mineral
rights to which neither company ascribed value as a standalone.
Lake Way appears to be an ideal site for our SOP Demonstration
Plant and subsequent expansions. We expect it would result in
material time and cost savings for us and also bring significant
benefits to the Wiluna Community. It appears to have the best
combination in Australia of scale, brine chemistry, permitting and
infrastructure access and justifies the effort to prove its
potential. Work will continue in parallel at Lake Wells, where our
Mining Lease Application is in progress."
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 200km(2) .
Lake Way was identified due to its strategic location and
significant infrastructure advantages. 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.
As described in SLP's ASX Announcement dated 12 December 2017,
Lake Way has been extensively explored and mined previously. A
paleochannel has been well defined along the Eastern edge of the
lake, including brine sampling at depth and test pumping of the
basal aquifer.
Competent Persons Statement
The information in this report that relates to Exploration
Results for Lake Way is based on information compiled by Mr Ben
Jeuken, who is a member Australian Institute of Mining and
Metallurgy. Mr Jeuken is employed by Groundwater Science Pty Ltd,

experience, which is relevant to the style of mineralisation and
type of deposit under consideration and to the activity, which he
is undertaking to qualify as a Competent Person as defined in the
2012 Edition of the 'Australasian Code for Reporting of Exploration
Results, Mineral Resources and Ore Reserves'. Mr Jeuken consents to
the inclusion in the report of the matters based on his information
in the form and context in which it appears.
Forward Looking Statements
This announcement may include forward-looking statements. These
forward-looking statements are based on Salt Lake's expectations
