Cypress Reports Up to 2,940 PPM Li from Dean Lithium Project in Clayton Valley, NevadaOctober 6, 2016
Vancouver, BC - Cypress Development Corp. (TSX-V: CYP) (OTCBB: CYDVF) (Frankfurt: C1Z1) ("Cypress" or the "Company") is pleased to announce, further to its News Release of September 8th, that the Company has received assay results from Cypress' initial Phase 1 exploration program on its new Dean Clayton Valley Lithium Brine/Clay Project in Esmeralda County, Nevada.
Cypress' Dean Clayton Valley Lithium Project, Nevada claims map:
Cypress' Dean Project is located in the heart of the Clayton Valley lithium brine exploration area of Esmeralda County, Nevada. The Company's 2700 acre Dean Claim Group 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' existing Glory Clayton Valley Project, optioned to Pure Energy, on its southern boundary.
In September, Cypress initiated a Phase 1 detailed surface sampling program on the Company's new Dean Project. 55 samples were collected and submitted for analysis for lithium content from the abundant, green evaporite-rich volcanoclastic claystone exposure on the property and have returned very positive lithium results ranging between 340 ppm Li to 2,940 ppm Li with an overall average grade of 925 ppm Li achieved.
Cypress' Dean Clayton Valley Lithium Project sampling map:
The Esmeralda geological formation is the known host rock unit for both lithium brine production and for lithium mineralized evaporate rocks currently being explored by Cypress in Clayton Valley. Known structures on the Dean Claims include the dominant Angel Island fault, a district-scale strike slip fault which trends through strongly fractured surrounding rock units. This zone of pervasive fracturing is being targeted as a pathway for brines to invade the underlying ash layers and also as a zone of high porosity which itself could host lithium brine zones along strike. Deformation along the Angel Island fault is a complicated but highly prospective zone for the existence of structural traps for lithium brines.
Don Huston, President, stated: "Cypress is very pleased with the results attained from its initial sampling program for lithium on the Company's new Dean Claims. The initial lithium numbers encountered to date are very encouraging. Cypress will now establish a detailed grid pattern across all 2700 acres of the property and proceed with a further tightly controlled sampling program coinciding with a detailed geological mapping program. Cypress has been proactive in exploring the central Clayton Valley for lithium since late 2015. The Company's objective continues to be the assembling of prospective land packages with lithium-rich exploration potential concentrated on ground immediately adjacent to current lithium production as well as tied on to the best advanced-stage exploration projects undergoing active development for new lithium resources in the basin. The acquisition of the Dean Claims is the latest result in this effort".
Lithium Leach Testing of Claystones at Cypress' Dean Project:
Initial surface sampling of the Dean Claims Group has revealed a large area of strong lithium mineralization in calcareous, volcanoclastic, mudstones, claystones and volcanic ash units. The mineralization is essentially identical to the acreage now being jointly explored by Cypress and Pure Energy Minerals on the south boundary of the Dean Claims. Cypress is proceeding with additional solubility studies with the Dean assays to determine the amount of lithium extraction possible from the claystones. A modified weak Aqua Regia leach process (ME-MS41W) and a deionized water leach process (ME-MS03) will be done by ALS / Chemex lab in Reno to provide further data on the feasibility of a large scale leach extraction method of lithium from the abundant mineralized claystones.
Previous lab test on claystones from Cypress' Glory Project, to the immediate south of Cypress' Dean property, have shown an impressive average of 35% Li recovery using a deionized water leach and 95% Li recovery using a weak Aqua Regia leach process.
The data suggests that a readily soluble non-hectorite mineral form of lithium-rich claystone exist at surface over wide areas of Cypress' Glory Clayton Valley project.
Quality Control and Quality Assurance:
All samples were submitted to ALS Chemex Labs in Reno, Nevada, for analysis using an ME-ICP61, 33 element four acid digestion ICP method.
