Cypress Drills 107 meters of 1134 ppm Lithium, Expands Mineralized Zone in Clayton Valley, Nevada - Seite 3

Summary of Leach Tests
Test	Sample	Head Assay	Temp	Extraction (%)
ID	ID	ppm Li	oC	Li
OL-02	Oxidized	860	room	39
RL-02	Reduced	1100	room	55
OL-06	Oxidized	860	80o	74
RL-06	Reduced	1100	80o	74

Samples were ground to minus-10 mesh and leached with a solution of 5% sulfuric acid for 4 hours at 10% solids. The leach solution was monitored but no additional sulfuric 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.
