      CYPRESS DRILLS 102.7 METERS OF 1029 PPM LITHIUM IN CLAYTON VALLEY, NEVADA

      Cypress Development Corp. has released results from the company's first three holes completed in its fall 2017 drill program at its 100-per-cent-owned Dean and Glory lithium properties in Clayton Valley, Nevada. The results include an intersection of 102.7 metres of 1,029 parts per million lithium within DCH-11 on the Dean property.

      Cypress has completed five core holes in its fall program on the Dean property. The results summarized here are from the first three holes, DCH-10, -11 and -12. Results from the remaining holes on Dean are expected in December and will help in determining where additional drilling is needed. In the meantime, as previously announced, the drill rig was moved south onto the adjoining Glory property where drilling is continuing and seven holes are planned.

      Dean drilling highlights:
      • The intersection in DCH-11 of 102.7 metres of 1,029 ppm Li demonstrates continuity over a large thickness of claystone which extends north from the south end of Dean.
      • DCH-10, 400 metres to the southeast of hole DCH-11, intersected 63.5 metres of 1,014 ppm Li. The hole was abandoned due to ground conditions and ended in 1,068 ppm Li. Mineralization here remains open at depth and to the east.
      • DCH-12, 400 metres northwest of DCH-11, intersected 62.8 metres averaging 677 ppm Li. The hole further demonstrates continuity of mineralization in the claystone, which remains open to the west and north.
      • In DCH-10, dark green to black ash-rich mudstones were encountered at a depth of 53.4 metres, which averaged 1,367 ppm Li over 10 metres and included one metre of 2,240 ppm Li. This is the first time Cypress has encountered these dark mudstones in drilling.
      • DCH-11 included an interval of consistently higher grades over 36.9 metres, starting at a depth of 8.2 metres. Samples here averaged 1,308 ppm Li over 36.9 metres and suggest a higher-grade zone may exist within the overall northeast trend.
      • All holes to date clearly show a large, tabular, lithium-bearing formation underlying the Dean property.
      • Drilling has outlined a large area of mineralization of approximately four kilometres in length and two kilometres in width at Dean.
      • Laboratory work continues to test the solubility of the lithium-enriched claystone under varying conditions and reagents.




      SUMMARY OF DEAN DRILL HOLES DCH 10, 11 AND 12 Lithium values Drill hole From To Length Min Max Avg (m) (m) (m) (ppm) (ppm) (ppm) DCH-10 0.8 64.3 *63.5 482 2,240 1,014 includes 53.4 63.4 10.0 1,048 2,240 1,367 DCH-11 0.3 103.0 102.7 546 1,737 1,029 includes 8.2 45.1 36.9 1,101 1,737 1,308 DCH-12 0.6 63.4 62.8 475 992 677 * DCH-10 ends in 1,068 ppm Li.


      The fall 2017 program was planned for 12 to 14 drill holes, up to 1,500 metres of core. All holes are vertical and drilling to be divided between Cypress's contiguous Dean and Glory properties. The properties cover an area totalling 4,220 acres and are 100 per cent controlled by Cypress. Drilling is now under way on Glory.

      Cypress believes its lithium-bearing claystone deposit in Clayton Valley, which is located due east of Albemarle's Silver Peak lithium brine operation, has the potential to become a significant source of lithium. Cypress is very active in Nevada, with its geological team focused on systematically exploring its properties for lithium. In addition to the drilling in progress, Cypress is continuing with laboratory testwork to determine the nature and distribution of the lithium in the claystone with the goal of identifying a cost-effective means of extraction.

              CYPRESS DRILLS 107 METERS OF 1134 PPM LITHIUM, EXPANDS MINERALIZED ZONE IN CLAYTON VALLEY, NEVADA

              Cypress Development Corp. has released results from two more core holes from the company's Clayton Valley, Nevada, drill program. Today's results include an intersection of 107 metres of 1,134 parts per million lithium within hole DCH-13 and 76 m of 733 ppm Li within hole DCH-14, both located on the Dean property. Hole DCH-13 represents one of the longest and higher-grade drill results from the property to date as Cypress continues to expand the lithium mineralized zone.

              Drilling highlights:
              • The intersections reported are the weighted average of all core recovered in each hole, from surface to the end of the hole. The results continue to demonstrate the presence of lithium mineralization over a large thickness of claystone.
              • The two holes are located in between the fence of holes in DCH-10, -11 and -12, to the southwest and DCH-09, to the northeast, and support the observed continuity of mineralization over a long northeast trend, extending approximately four kilometres in length and two kilometres in width across the Dean property.
              • In DCH-13, the lithium values increased at depth, starting 24.8 m below surface, and averaging 1,206 ppm Li over 88.4 m.
              • DCH-13 ended in 3.0 m of 912 ppm Li. The hole was terminated due to operating constraints and remains open at depth.
              • The grade increase was observed coincident with a redox boundary, where material above the boundary is oxidized and light grey in color, and material below the boundary is reduced and dark grey and green to black in colour. This redox boundary has been observed at similar depth from surface in other drill holes.
              • Drilling in the fall 2017 program has been completed, with four holes drilled on the Glory property to the south. Results from these holes are anticipated later in the month.

              Laboratory test work

              Extraction studies are under way to determine the solubility of the lithium and other mineral constituents within the claystone. Representative samples of oxidized and reduced material from DCH-05 were delivered to SGS in Lakefield, Ont. These initial bench-scale scoping tests revealed moderate extractions of lithium in sulphuric acid solution, increasing to 74 per cent in both sample types with increasing temperatures. The extractions were achieved with relatively low additions of sulphuric acid for lithium-bearing claystone deposits, measured at a rate of 140 kilograms to 170 kg of acid per tonne of material. The results are encouraging and clearly indicate that the extractions and acid consumptions of Cypress's Clayton Valley claystone are significantly better than seen in refractory claystone deposits. Further test work is under way to improve the results by refining the leach conditions, checking for any mineralogical variability across the properties, and determining methods of recovery of the lithium from the leach solutions.

              Samples were ground to minus 10 mesh and leached with a solution of 5 per cent sulphuric acid for four hours at 10 per cent solids. The leach solution was monitored but no additional sulphuric acid was required to maintain the pH below 1.0. The mixture was then filtered and rinsed and residue and solutions submitted for assay.

              Resource definition

              The company is reviewing drill results. Additional holes are planned for the first quarter of 2018 to infill and connect the Dean and Glory areas of drilling. The company anticipates the further work will support a resource estimation and preliminary economic assessment (PEA) upon completion of the drilling, metallurgical studies and gathering necessary economic data.

              Cypress believes its lithium-bearing claystone deposit in Clayton Valley, which is located due east of Albemarle's Silver Peak lithium brine operation, has the potential to become a significant source of lithium. The company is working to advance the project into development by following its program of exploration drilling and metallurgy. Cypress is very active in Nevada, with its geological team focused on systematically exploring its properties for lithium.

                  As I have suggested before, the most promising of the early-stage lithium explorers is Cypress Development Corp (TSX.V:CYP), whose project in Nevada’s Clayton Valley is close to the only producing lithium mine in the United States, yet with a very interesting geological footprint that is unlike any other property in the valley. And with excellent results from a 2017 drill program recently released and plenty of blue sky upside, this is perhaps THE lithium junior to watch in 2018.

                    CYPRESS EXPANDS LITHIUM TREND BY OVER 2 KILOMETERS AT CLAYTON VALLEY PROJECT, NEVADA

                    Cypress Development Corp. has released results from the first four core holes on the Glory claims at the company's 100-per-cent-held project in Clayton Valley, Nevada. The drilling extends the trend of lithium mineralization by more than 2 kilometers south and west from the Dean claims, where, as previously reported, 14 drill holes in 2017 encountered lithium-bearing claystone over an area averaging 4 kilometers by 2 kilometers and averaging 78 meters in depth. The four holes reported today represent the first drilling on the Glory claims. All four holes encountered lithium values averaging from 600 to 900 ppm Li from surface to depths up to 60 meters.

                    Highlights:
                    • Lithium values were encountered in all 4 core holes at Glory, including 47.5 meters of 927ppm Li in GCH-04
                    • The results extend the trend of mineralization by more than 2 kilometers south and west of Dean, further demonstrating the large lateral extents of the lithium-bearing claystone
                    • Given success of its drill program, Cypress will recommence drilling shortly with details forthcoming
                    • An independent resource estimate is underway

                    New Technical Report and Upcoming Drill Program at Clayton Valley Project:

                    In related activity, the Company has engaged Global Resource Engineers, of Denver, Colorado, to prepare a resource estimate for the Dean property. A NI 43-101 Technical Report on the geology and drilling of Dean has been completed and will be filed on SEDAR. Metallurgical testing, as reported in a previous press release on January 9th, has shown the lithium in Dean core is soluble in a solution of sulfuric acid. Testing is continuing at two independent labs, using Dean core from holes DCH-2 and DCH-5. Further results are expected to be reported this month.

                    Given the success of this recently completed drill program, the Company will recommence drilling shortly on Dean. Further details of this upcoming drill program are forthcoming.

                      An INITIAL 43-101 compliant resource estimate in time for PDAC is very possible. Metallurgy is also coming. Along with a considerable amount of new drilling.

                      It's very possible CYP soon shows the world 80% plus recovery, with great economics, on an up to billion ton resource..

                      CYP address is

                      lithium, Clayton Valley, USA.

                      I expect a lot of attention being focused on CYP. PP coming free trading soon, guys are on a road trip

                      to get the selling soaked up, get some new people positioned.

                        CYPRESS RESUMES DRILLING AT CLAYTON VALLEY LITHIUM PROJECT, NEVADA

                        Drilling has resumed at Cypress Development Corp.'s 100-per-cent-owned lithium project in Clayton Valley, Nevada.

                        The first holes will be drilled on the Dean property, where, in 2017, 14 holes intersected lithium-bearing claystone to depths of 112 meters below surface. As announced in the Feb. 7th press release, an independent consulting firm, Global Resource Engineers (GRE), of Denver, Colorado, is engaged to prepare a resource estimate and accompanying technical report based on the 2017 drill results. A site visit has taken place, during which split core samples were selected for check assays and select surface samples were twinned under the direction of a GRE geologist. Additional work is underway.

                        After review of the 2017 drilling, the initial three holes of this program are to be in the southeast corner of the Dean property. One hole will test continuity between two fence lines in previous drilling, another will be drilled near DCH-10, which was terminated in mineralization due-to poor ground conditions, and the final will step-out towards the southeast corner of the claim block. Drilling is expected to be completed by early March and the results included by GRE in the resource estimate.

                        Upon completion of the drilling on Dean, an additional five to seven holes are planned to further target the Glory property. As reported in the February 7th news release, the first four holes drilled on Glory extended the trend of mineralization south and west from Dean by over 2 kilometers. The next holes on Glory will focus on defining mineralization in the eastern half of the property south of the higher grade holes on Dean.

                          CYPRESS CONFIRMS LEACH RESULTS FOR CLAYTON VALLEY LITHIUM PROJECT IN NEVADA

                          Cypress Development Corp. has provided additional results that confirm the high solubility of lithium in claystone from its 100-per-cent-owned Clayton Valley project in Nevada. Extraction Curve for Reduced Sample, DCH-05

                          As previously reported (January 9, 2018 press release), lithium extractions of 74% were obtained for both oxidized and reduced claystone samples from drill core from hole DCH-05, leached in a solution of 5% sulfuric acid heated to 80degreeC. Subsequent tests reported today show lithium extractions of 67% for the oxidized claystone and 80% for the reduced claystone sample, leached under identical conditions but using a solution of 10% sulfuric acid heated to 50degreeC. These results are in line with previous results and continue to demonstrate the solubility of lithium found in the subsurface claystone at Clayton Valley using sulfuric acid. An opportunity to improve extractions by adjusting leach conditions is now also apparent.

                          The Company is also pleased to report core drilling is underway and the first of three additional holes, DCH-15, was completed to a depth of 127 meters, and encountered oxidized and reduced claystone types throughout. As previously announced, this hole was located to test the continuity between two fence lines of holes from the previous drilling. Drilling of the next two holes is expected to be completed by early March and the results included in the upcoming resource estimate.

                          Cypress' Lithium Project

                          Cypress' primary focus is the Company's Dean and Glory claim blocks, located in Clayton Valley, Nevada, immediately east of Albemarle's Silver Peak mine, North America's only lithium brine operation. Recent exploration by Cypress has discovered an extensive deposit of lithium-bearing claystone, which has been tested by drilling over a seven-kilometer trend across Cypress' 4200-acre properties.

                          The lithium mineralization is contained within interbedded lacustrine (lake basin) stratigraphy. These lake bed, volcanic ash rich claystone have been uplifted to their present outcropping position by movement along the Angle Island fault, a typical Walker Lane style shear zone with both lateral and vertical movement. Lithium content of the claystone was found to range up to 3800 ppm on surface. In Cypress' drilling, the values vary up to 1760 ppm Li over thicknesses of up to 112 meters. In most of Cypress' holes, a redox boundary has been encountered. This change occurs at depths of between 20 to 30 meters and is seen where claystone above the boundary is oxidized and light grey in color and claystone below is reduced and dark grey and green to black in color. Composite samples for metallurgical tests were prepared recognizing the redox boundary and designated as Oxidized Sample if above the redox boundary or Reduced Sample if below it.

                          Laboratory Test Work

                          The Company is continuing laboratory work to determine the solubility of the lithium and other mineral constituents within the claystone. The Company reported at the time that a portion of the lithium is water soluble from simple assay-level tests. Bench-scale testing began in August 2017, when representative samples of oxidized and reduced material from hole DCH-05 were delivered to SGS in Lakefield, Ontario. The primary observation from these tests is the lithium in the subsurface material, at least from DCH-05 core, is almost totally insoluble in water. This contradicts the previously reported tests, which only utilized surface sample material, and suggests the water-soluble lithium occurs as a product of surficial weathering.

                          Further tests were completed at SGS using various acids and conditions, with the best results occurring in sulfuric acid. In these tests, extractions of 74% were achieved in both the oxidized and reduced samples. These tests used the following conditions, ground to minus-10 mesh, leached for 4 hours at 10% solids in 5% sulfuric acid and heated to 80degreeC. These extractions were achieved with relatively low acid additions, measured at 140 kg to 170 kg of sulfuric acid per tonne of material, and clearly contrast with the low extractions and high acid consumptions seen in hectorite-bearing claystone deposits.

                          Present Results

                          Further tests were conducted at SGS on the core from DCH-05. Following the observation where temperature set to 80degreeC showed a positive affect and increased the solubility of lithium significantly, subsequent tests were done with the temperature reduced to 50degreeC and acid concentration increased to 10%. These changes produced a mixed result, reducing the extraction in the oxidized sample to 67% (test OL-07), while increasing the extraction in the reduced sample to 80% (test RL-11). The results are consistent with the previous tests (OL-06 and RL-06), confirming the solubility of the lithium with sulfuric acid for DCH-05 core, and demonstrating the opportunity to improve extractions by adjusting leach conditions. An additional test was done on the reduced material to generate a time-extraction curve, shown below, which shows dissolution of the lithium is relatively fast, reaching 50% in the first hour, and may continue to increase beyond 4 hours.

                          Further tests are ongoing with the following goals: 1) refining the leach conditions, 2) checking for mineralogical variability from hole to hole, and 3) determining effective means of recovering the lithium from the leach solutions. In December, samples were sent to a second independent laboratory, Continental Metallurgical Services, in Butte, Montana. The two samples were composites of oxidized and reduced intervals from hole DCH-02. A one-hour leach of these samples, using 10% sulfuric acid at 10% solids and 50degreeC, returned lithium extractions of 62% and 65%, respectively. These results, if plotted on the extraction curve from hole DCH-05, plot somewhat higher, possibly indicating differences do exist in mineralogy from hole to hole, or other differences in laboratory conditions, such as intensity of agitation during leaching. The results are consistent, however, with the observation that the lithium in the subsurface claystone can be leached with high levels of extraction in sulfuric acid.

OL and RL series samples were core from DCH-05, tested at SGS and leached for 4 hours. Samples Li-A1 and Li-A2 were core from DCH-02, tested at Continental Metallurgical Services, and leached for 1 hour. In all tests, the leach solution was monitored but no additional sulfuric acid was required to maintain an acidic pH. The mixture was then filtered and rinsed with residue and solutions submitted for assay.

                            Potential, coming very soon, tonnage numbers could be very impressive.

                            3,500 meters length X 2,000 meters width X 70 meters thick X 1.75 specific gravity (density) = 857,500,000t of lithium enriched claystone (up to approx. 4.5mm tonnes of LCE).

                            Thats more LCE, way more LCE (with half the outstanding shares), than most others have lithium.

                            By the way? Battery grade LCE, in 2017, sold for an average of US$13,900.00 ton.
