Cypress Samples 3,070 ppm Li at Clayton Valley Lithium Project, Nevada

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb. 22, 2016) - Cypress Development Corp. (TSX VENTURE:CYP)(OTCBB:CYDVF)(FRANKFURT:C1Z1) ("Cypress" or the "Company") is pleased to report recent surface sampling results from the Company's 1280 acre Clayton Valley Lithium Brine Project located in Esmeralda County, in the state of Nevada, USA.

Cypress' Clayton Valley Project is located on the south flank of "Angel Island" and immediately southeast of the Albemarle Silver Peak lithium brine mine. The acquired claims share their western boundary with placer claims controlled by Pure Energy Minerals. Pure Energy has identified a lithium resource at its northern resource area (see Pure Energy's news release July 28, 2015), that is located to the immediate west of Cypress' established boundary.

Clayton Valley is located within the Basin and Range Province in southern Nevada and is an internally drained, fault bounded and closed basin. Basin-filling strata compose the aquifer system which hosts and produces the lithium-rich brines.

Cypress' highly prospective "Glory" and "Angel" claims are located within 0.5 miles (<1000m) south of current and past producing lithium brine wells belonging to the Albemarle Silver Peak mine. Cypress' Clayton Valley claims are located in an active area of surface hectorite clay lithium mining and lithium exploration. Highways and electric power are in place and exploration resources needed are readily accessible.

The Albemarle Silver Peak mine is the only operating brine based lithium mine in North America. The Silver Peak area is one of the oldest mining areas in Nevada having produced substantial amounts of silver, gold and other minerals. The Silver Peak mine began operations in 1967 to mine lithium by low cost evaporation ponds and has produced lithium since then. The lithium concentration in the production brines were reported in 2001 to average 160 ppm (160 mg/litre) (Garrett Report, 2004). Lithium concentrations in the brines in Clayton Valley have been relatively consistent in the 150 -200 ppm (mg/litre) in recent history. In general, the brines from the north part of the Clayton Valley are Sodium/Chloride (Na/Cl) in composition and have lithium concentrations in the range of 60 - 400 ppm (mg/litre) Li.

Lithium brines have been extracted from shallow levels within the basin for almost 50 years. The majority of these brines have been pumped from subsurface aquifers on the flanks of Angel and Goat Islands. This spatial association of brine production from the flanks of the Cambrian age bedrock blocks is highly encouraging for the potential of the Cypress land position.

Surface sampling of green to bone white claystones was completed at Cypress' Clayton Valley Project at the end of January in an area within the northwest portion of the property on the west flank of Angel Island. Angel Island is one of several isolated exposures of highly deformed and metamorphosed rocks of Cambrian age that are surrounded by basin fill evaporite rocks herein referred to as the "claystones". These claystones are not well understood in terms of age but are definitely part of the recent basin fill evaporite rocks of the Clayton Valley and are thought to be less than two million years old based on work completed by the USGS and other research geologists. These exposures likely represent uplifted portions of the stratigraphy within which the lithium brines of the basin are produced.

The results of recent, systematic sampling of surface claystones reported here confirms the target model being used by Cypress. The results are displayed in Tables 1 and 2 below. Table 1 samples were randomly collected along the contact of the Cambrian age rocks and the basin fill claystone evaporite rocks. Table 2 lithium (Li) numbers are from samples of the Cambrian rocks above a complex contact with the topographically lower claystones.

A second series of samples were systematically collected from an approximate 300 foot wide traverse through the claystones starting at first exposure on the basin side gravel-claystone contact (west) and ending at a brecciated vertical fault contact of the claystones with the Cambrian rocks of Angel Island (east). The samples were collected at an approximate spacing of 25 feet. The results of these samples are displayed in table 2.

The assays from the systematic traverse samples average >1500 ppm Li and are accompanied by a typical suite of other evoporite rock mineralization, including one sample with >1% strontium.

The results suggest a strong possibility of an essentially continuously mineralized volume of claystone at surface on the Cypress property in a position immediately east of both brine production wells at Albemarle Silver Peak mine and the north resource area of Pure Energy Minerals project.

It is important to note that the geometry of the claystone bedding is not readily apparent at the sample sites due the presence of a ten to twenty cm thick weather crust which completely masks the bedding of the claystones. Traverses completed in other areas of the property and along the flanks of Angel Island have shown that the claystones are locally highly deformed. Larger-scale exposure of clean rock faces along the traverse will be required to help determine whether the samples are localized within discrete beds or are in fact of a robust, massive nature.

Don Huston, President of Cypress stated: "We are pleased with the results of our initial surface work on the Glory claims of our Clayton Valley project when compared to nearby brine production grades. We are at an early stage with this project and much work remains to be done to investigate the subsurface where we expect to find ground water aquifers within deeper portions of the same mineralized claystone evaporate sequence that is currently being explored at surface. We are confident that the position of our property adjacent to production wells and defined resources combined with current surface assay results indicates that Cypress is well situated to create value for our shareholders as we advance the exploration of our claims."

Cypress is currently planning follow-up work at its Clayton Valley Project to better define this near surface lithium mineralization identified by the recent sampling program. The Company is planning a sub-surface exploration program including seismic data acquisition and we look forward to the identification of high quality drill targets for lithium brines within 2016.

All samples were assayed by ALS Chemex using a four acid digestion / ICP-Mass Spec method. Note that no effort was made to select the material for the samples. All samples were collected by digging through a powdery crust followed by collection of well indurated claystone material below the crust.
