CYPRESS DEVELOPMENT ENGAGES THYSSENKRUPP NUCERA FOR
DESIGN AND ENGINEERING OF CHLOR-ALKALI PLANT IN FEASIBILITY STUDY
October 27, 2022 – Vancouver, Canada – Cypress Development Corp. (TSXV: CYP) (OTCQX: CYDVF)
(Frankfurt: C1Z1) (Cypress or Company) is pleased to announce the selection of thyssenkrupp nucera
USA, Inc. (thyssenkrupp nucera) to provide the design and engineering for the chlor-alkali plant as part of
the ongoing Feasibility Study on the Company’s Clayton Valley Lithium Project in Nevada, USA (Project).
The chlor-alkali plant is an essential component which will allow the Project to self-generate two key
reagents required for processing lithium-bearing claystone through to a Li2CO3 (lithium carbonate)
product.
“The Company’s selection of thyssenkrupp nucera is another important step towards completion of the
Feasibility Study for the Project’s production of lithium carbonate. Their experience and proven track
record as an electrolysis technology company with worldwide knowledge in the chlor-alkali field will add
to our Feasibility Study” stated Bill Willoughby, President, and CEO of Cypress Development.
thyssenkrupp nucera USA Inc. is the U.S. subsidiary of thyssenkrupp nucera AG & Co. KGaA, an
international company that offers world-leading technologies for high-efficiency electrolysis plants, which
includes chlor-alkali electrolysis, HCl electrolysis, and alkaline water electrolysis. thyssenkrupp nucera’s
scope in the chlorine electrolysis business includes the supply and services around engineering, supply of
all major plant equipment, supervision of the erection and commissioning activities, training of the
operating personnel as well as holistic 360-degree service solutions for the entire lifecycle of a plant.
thyssenkrupp nucera’s scope of work will include the development of a facility concept for treatment of
the recovered brine stream from Cypress’ process and ensure compatibility with the membrane
electrolysis cells of a chlor-alkali plant. Standardized and proprietary e-BiTACv7 BiPolar type membrane
cell electrolyzers from thyssenkrupp nucera serve as the heart of the chlor-alkali plant to generate the key
reagents HCl (hydrochloric acid) and NaOH (sodium hydroxide) required to process the lithium ore. The
NaCl (sodium chloride) and H2O (water) molecules present in the recovered brine are electrolyzed to
produce Cl2 (chlorine), H2 (hydrogen) and the sodium hydroxide, where then outside of the cells, the
chlorine and hydrogen molecules are combined to produce hydrochloric acid.

Feasibility Study Update
The Company’s Feasibility Study on the Project commenced in March 2022 under the direction of Wood
PLC (Wood), with support from Global Resource Engineers, Continental Metallurgical Services, WSP USA
Environment & Infrastructure Inc., and Cypress.
Progress on the Feasibility Study is advancing as planned. Wood and the supporting teams have completed
or are near completion of several key items, including resource and reserve estimates, mine plan,
processing plant design, and tailings and waste storage facilities.
Positive results from test work conducted at Saltworks Technologies Inc. (Saltworks) (see news release
dated September 19, 2022), where high purity lithium carbonate was made at Saltworks from
concentrated lithium solutions produced at Cypress’ Lithium Extraction Facility in Nevada.
Saltworks has since completed a second phase of testing which examined the production of lithium from
the blowdown-brine stream collected during the lithium carbonate concentration in the first stage of
testing. We are pleased to report these results are positive and confirm the viability of an increase in
lithium recovery via re-concentration of the blowdown-brine and production of additional lithium
carbonate solids. Results from third-party laboratory analysis are pending for lithium carbonate quality
obtained during this test. This step has the potential to significantly reduce the volume required to be
recycled back to the upstream direct lithium recovery (DLE) plant and reduce size and capital cost of the
DLE plant.
Based on the progress and results from Saltworks, Cypress is focusing on lithium carbonate as the end-
product for the Feasibility Study and has engaged Saltworks to provide the engineering and design for the
final steps in producing lithium carbonate. Based on timelines for the major components and cost analysis,
as well as to allow thyssenkrupp nucera sufficient time to complete its design and optimization studies,
the Company expects the Feasibility Study to be completed in the second quarter of 2023.
