Standard Lithium Ltd.: Standard Lithium Acquires Lithium Brine Exploration Rights in Productive Smackover Formation in Arkansas

VANCOUVER, British Columbia, 2018-01-08 11:00 CET (GLOBE NEWSWIRE) --
Standard Lithium Ltd. ("Standard Lithium" or the "Company") (TSXV:SLL)
(OTCQX:STLHF) (FRA:S5L) is pleased to announce that the Company has signed an
Option Agreement with TETRA Technologies Inc. (TETRA), a non-affiliated
NYSE-listed company, to acquire the rights to conduct exploration, production
and lithium extraction activities on up to 33,000 acres of brine leases located
in an area where the Smackover Formation is known to be highly productive in
southern Arkansas, USA. 

Standard Lithium's Chief Executive Officer, Mr. Robert Mintak commented, "In
our search for opportunities of significance, this is one that could really
move the needle.  We believe the Smackover may be one of the lithium industry's
most promising regions to develop, given the potential resource size and
large-scale brine-handling infrastructure in the region.  This agreement
highlights our excellent working relationship with TETRA, and signing this deal
allows Standard Lithium access to the last available large lease package in the
key brine production zone of the Smackover." 

Project Highlights:

  -- Up to 33,000 acres of brine leases in key brine production fairway in
     southern Arkansas, adjacent to producing Albemarle leases;
  -- Historical data from Standard Lithium lease area shows 370-424 mg/L lithium
     in brines (Moldovanyi and Walter, 1992);
  -- Arkansas currently produces the equivalent of 42.6 million m3
     (9,380,000,000 gallons) of brine per year (based on Arkansas Oil and Gas
     Commission reported average brine production from 2010-2016), almost
     entirely from the Smackover Formation;
  -- Low risk, well understood geology and chemistry;
  -- Significant infrastructure, roads, power, water, trained workforce in
     region; and
  -- Existing brine extraction, processing and re-injection permitting regime.

President and Chief Operating Officer, Dr. Andy Robinson also commented, "the
Company chose the Smackover Formation as a key development target, precisely
because it combines a very large resource potential, with well-studied and
documented geology and hydrogeology, along with a permitting regime that has a
long history of approving operations that remove, process and re-inject massive
volumes of brine.  Combined with a wealth of existing infrastructure in the
project area (power, rail, gas, water, trained workforce, cheap reagents etc.),
this makes Standard's new opportunity in Southern Arkansas the perfect location
to locate a modern lithium brine processing operation.  Due to the wealth of
already-available data from our new project area, we can start the process of
compiling a maiden resource estimate for this large lease package extremely
quickly, with a minimum of additional intrusive investigation." 

Transaction Terms
Under the terms of the Option Agreement with TETRA, the Company will be granted
the rights in consideration for a series of cash payments, as well as certain
ongoing royalties tied to lithium production from the properties.  In
consideration of the execution of the Option Agreement, the Company has made a
non-refundable cash payment to TETRA of US$500,000, with further cash payments
owing to TETRA as follows: 

  -- US$500,000 on or before the date that is thirty (30) calendar days
     following the Agreement Date;
  -- an additional US$600,000 on or before the date which is twelve (12) months
     following the Agreement Date;
  -- an additional US$700,000 on or before the date which is twenty-four (24)
     months following the Agreement Date;
  -- an additional US$750,000 on or before the date which is thirty-six (36)
     months following the Agreement Date; and
  -- an additional annual payment of US$1,000,000 on or before each annual
     anniversary of the Agreement Date, beginning with the date that is
     forty-eight (48) months following the Agreement Date, until the earlier of
     the expiration of the 10 year exploratory period or, if the Company
     exercises the Option, the Company begins payment of the Royalty.

Upon commercial production, the Company will pay TETRA a two and one-half
percent (2.5%) royalty on gross revenue derived from the sale of lithium
produced from the properties, subject to a minimum annual royalty payment of
US$1,000,000.
