Cypress Development and Lilac Solutions Demonstrate High Lithium
Recoveries from Clayton Valley Project in Nevada
Vancouver, BC - Cypress Development Corp. (TSX-V: CYP) (OTCQB: CYDVF)
(Frankfurt: C1Z1) (“Cypress” or “the Company”) and Lilac Solutions (“Lilac”) are
pleased to announce the successful demonstration of high lithium recoveries for
Cypress’ 100% held Clayton Valley Project in Nevada utilizing extraction processes
developed by Lilac Solutions. Lilac Solutions is a lithium extraction technology
company based in Oakland, California. Cypress’ Clayton Valley Project is located 215
miles southeast of Reno, Nevada and features a large clay-hosted lithium deposit with
3.8 million tonnes of lithium carbonate equivalent in a NI 43-101 Indicated Resource
category (see PEA NI 43-101 Technical Report).
Today, most lithium is produced from lithium brine resources in South America or hard-
rock resources in Australia. Clay resources offer a potential new third branch of the
lithium resource base and include large domestic United States resources such as
Cypress’ Clayton Valley project. However, to date, clay resources have not achieved
commercial lithium production due to technical challenges associated with lithium
extraction. Cypress and Lilac are addressing these challenges together with a highly
efficient and modern mining process.
“Cypress has established one of the largest lithium resources in the United States and
Lilac is excited to work with the Cypress team to move this domestic resource towards
commercial production,” said David Snydacker, CEO and founder of Lilac Solutions.
“The United States is home to a variety of important players i n the electric vehicle
sector and is an epicenter for innovation. This Nevada project has the potential to
deliver the critical raw material needed by every North American automaker to
compete over the next decade.”
Cypress has developed an innovative leaching process which reduces the quantity of
sulfuric acid needed to leach lithium from clay. After the lithium is leached into a sulfate
solution (the “leachate”), Lilac can extract lithium from the leachate to produce a high-
purity lithium solution (the “ eluate”), which can be fed into conventional process
equipment to produce a high-purity lithium carbonate or lithium hydroxide product.
Lilac extracted lithium from the clay leachate using Lilac’s patented ion exchange
process. Following initial engineering work on the Cypress leachate, Lilac was able to
2
recover 83% of lithium from the leachate while simultaneously rejecting greater than
99% of sodium, potassium, and magnesium impurities. The remaining lithium in the
leachate can then be recycled back to t he leaching stage to effectively allow further
recovery of the lithium.
“Lilac’s results are promising and offers us another path forward to effectively recover
lithium from our process solutions” said Cypress’ CEO Dr. Bill Willoughby. “Our project
is a significant potential source of domestic lithium and we are pleased to be working
with Lilac in applying their ion exchange technology.”
Cypress and Lilac plan to ad vance engineering work towards a pilot plant and
commercial development. Cypress is now co mpleting a Pre -Feasibility Study which
incorporates the Lilac process.
William Willoughby, PhD., PE , CEO and director of Cypress Development is the
qualified person as defined by National Instrument 43 -101 and has approved of the
technical information in this release.

About Cypress Development Corp.:
Cypress Development Corp. is a publicly traded exploration company focused on
developing the Company's 100% -owned Clayton Valley Lithium Project in Nevada.
Exploration and development by Cypress has discovered a world -class resource of
lithium-bearing claystone adjacent to Albemarle's Silver Peak mine, North America's
only lithium brine operation. The size of the resource makes the Clayton Valley Project
a premier target that has the potential to impact the future supply of lithium for the fast-
growing global lithium-ion battery market.
Cypress Development Corp. has approx. 74.6 million shares issued and outstanding.
