Additional Core Holes Results At Clayton Valley

VANCOUVER, BC - Cypress Development Corp. reported results from two more core holes from the Company's Clayton Valley, Nevada drill program. The results include an intersection of 107 meters of 1134 ppm Li within hole DCH-13 and 76 meters 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.

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 4 kilometers in length and 2 kilometers in width across the Dean property. In DCH-13, the lithium values increased at depth, starting 24.8 meters below surface, and averaging 1206 ppm Li over 88.4 meters. DCH-13 ended in 3.0 meters 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 it is reduced and dark grey and green to black in color. This redox boundary has been observed at similar depth from surface in other drill holes, and drilling in the fall 2017 program has been completed, with 4 holes drilled on the Glory property to the south. Results from these holes are anticipated later.
