Cypress Reports on Dean Lithium Claystone Solubility Results
in Clayton Valley, Nevada
Vancouver, BC - Cypress Development Corp. (TSX -V: CYP) (OTCBB: CYDVF)
(Frankfurt: C1Z1) (“Cypress” or the “Company”) is pleased to announce that the
Company has received solubility study assay results from Cypress’ 2,700 acre Dean
Lithium Brine/Claystone Project located in the heart of the Clayton Valley lithium
exploration area of Esmeralda county, Nevada.

The Company's Dean Project is located adjacent to producing lithium brine wells
belonging to the Albemarle Silver Peak mine on its west boundary, Pure Energy's
resource area on its southwest boundary and Cypress' Glory Project, optioned t o
Pure Energy, on its southern boundary.
Highlights:
Cypress completes solubility studies on 48 previously assayed Dean
claystone samples;
A deionized water leach process returns 36.15% Li recovery on average;
A modified dilute acid leach process returns 94.72% Li recovery on average;
Permit application made to BLM, Nevada for a series of drill holes into new
Frontera Verda Zone;
Cypress anticipates drilling to begin at the end of January.
September and October 2016 surface sampling on the Dean Project has revealed a
2 square kilometer area of strong lithium mineralization up to 3,700 ppm Li (0.82%
Li20 equivalent) in calcareous, volcanoclastic, clay stones, mudstones and volcanic
ash units. The mineralization is essentially identical to the acreage be ing jointly
explored by Cypress and Pure Energy Minerals on Cypress’ Glory Project
immediately to the south.

Cypress has now completed solubility studies with 48 previously assayed claystone
samples from the Dean property. A modified dilute Aqua Regia (dilute acid) process
(ME-MS41W) and a deionized water leach process (ME-MS03) has been carried out
by ALS/Chemex lab in Reno, Nevada in order to provide Cypress with further data
on the potential feasibility of a large-scale leach extraction method of lithium from the
abundant mineralized claystone.
The additional assay procedures recently carried out on the samples by
ALS/Chemex from the Dean property clearly show that the lithium in the uplifted
exposed lake bed sediments is easily leached by a dilute acid solution and deionized
water process.

Several first order drill targets have been defined on the Dean property that include
extensive outcropping of altered gree n evaporate -rich volcanoclastic claystone /
mudstone exposures known as the Frontera Verde Zone. The Frontera Verde Zone
covers an area of greater than 2 square kilometers. The average lithium grade of the
Frontera Verde Zone is greater than 1500 ppm Li (>0.32% Li2O).

Donald Huston, President Cypress Development, stated "the results generated from
the most recent assays consisting of a highly dilute weak Aqua Regia solution and a
deionized water solution on the Dean Project samples has returned very
encouraging results relating to the lithium recovery from the claystone that is known
to exist on the majority of the Dean Project in Clayton Valley, Nevada. It is evident
that the use of differing solutions in the assay procedure , as noted above, that the
abundant lithium-rich claystone could be amenable to an extraction methodology that
4
could be cost effective with a very high recovery o f lithium content expected from
processing. Cypress ’ management are very encouraged with the progress seen to
date and will continue with work on potential lithium extra ction methods from the
claystone”.
All Data compiled by Cypress to date indicates that a readily soluble non -hectorite
mineral form of lithium -rich claystone exists at surface over wide areas of Cypress ’
Glory and Dean Clayton Valley projects.
Cypress has made application to the BLM, Nevada for an area of disturbance Permit
to allow for a series of drill holes into the new Frontera Verda Zone on the Dean
Project. The Company anticipates mobilizing a drill crew into the Clayton Valley by
the end of January.
Quality Control and Quality Assurance:
All samples were submitted to ALS Chemex Labs in Reno, Nevada for analysis using
a modified weak Aqua Regia (dilute acid) process (ME -MS41W) and a deionized
water leach process (ME-MS03). Blind sample blanks were inserted into the sample
sequences at a rate of approximately 1 per 20 samples.
