Overview
Electric vehicles aren’t just the hottest trend in Silicon Valley anymore. With wider cultural acceptance of green power alternatives, more accessible technologies and increasingly supportive legislative action, analysts expect this market and the demand for metals that supply it to climb to exponential highs.
In the United States, the government has named lithium a vital component in electric vehicle batteries and a strategic metal of importance. In 2021, President Joe Biden announced a US$2.3 trillion Infrastructure Plan, which outlines the intent to bring electric cars fully to the mainstream with investments of US$174 billion to promote this technology and construct necessary charging stations. This significant spending demonstrates exciting early-mover investment opportunities for lithium production companies and electric industries alike.
Cypress Development (
TSXV:CYP,OTCQX:CYDVF) is a Canadian based advanced stage lithium company, focused on developing its 100 percent-owned Clayton Valley Lithium Project in Nevada, USA. Cypress is in the pilot stage of testing on material from its lithium-bearing claystone deposit and progressing towards completing a Feasibility Study and permitting, with the goal of becoming a domestic producer of lithium for the growing electric vehicle and battery storage market.
In June 2022, Cypress announce positive results from the Direct Lithium Extraction (“DLE”) portion of its Lithium Extraction Facility (“Pilot Plant”) in Amargosa Valley, Nevada. Assays received from samples collected during continuous operating cycles in 2022, revealed an average lithium recovery of 99.5 percent within the DLE portion of the Pilot Plant. These high lithium recoveries were accompanied by high levels of impurity rejection.
Earlier in the month, the company announced that its Pilot Plant reached a milestone in the delivery of concentrated lithium solutions to two laboratories in Canada for further testing in the production of lithium products. “About 4,000 liters of concentrated lithium chloride solution have been delivered from the Pilot Plant to two Canadian laboratories. Each laboratory is now working to further treat the solutions, one to produce lithium carbonate, and the other, lithium hydroxide, as the final end product,” commented Bill Willoughby, President and CEO of Cypress Development. “These results will then be used to determine what additional steps are needed, if any, to attain battery-grade standards and evaluate the alternatives for producing these products in the ongoing Feasibility Study.”
In May 2022, Cypress acquired Enertopia’s (
OTCMKTS:ENRT) 160 acre lithium project, located adjacent to its Clayton Valley Lithium Project in Nevada. According to Dr. Willoughby, CEO of Cypress, "This is a strategic acquisition, and it will potentially aid in optimization, and production schedule development for our upcoming Feasibility Study.”
The commencement of a Feasibility Study, on the company’s Project, was announced in February 2022 that is currently being conducted by Wood PLC.. Wood PLC has completed numerous studies for mining projects in Nevada as well as relevant studies for various lithium projects globally, having just been awarded an agreement last month with Green Lithium, the mineral processing company, to be its Owner’s Engineer to build and operate the UK’s first large-scale commercial lithium refinery.
Earlier in the year, Cypress reported a successful Pilot Plant for extraction testing of lithium-bearing claystone from the Company’s Clayton Valley Lithium Project. The first full test was completed within 72 hours of continuous operation. “We have now completed 3, 7 and 14-day tests, achieving improvements in the operation and gaining important knowledge as we develop our unique lithium extraction process” stated Dr. Bill Willoughby, President & CEO of Cypress Development.
The pilot plant is operating at a rate of one tonne per day and is designed for correct interaction and testing of the major components within the extraction process and assessment of the resulting lithium products.
At the end of 2021, Cypress acquired a Water Rights Permit which allows for the appropriation of the public waters of the State of Nevada, in the amount of 1,770 acre-feet of groundwater per year for mining, milling and domestic applications. This amount represents the largest single volume of permitted water available in the Clayton Valley, which is a fully appropriated hydrogeographic basin. “Water resources in Nevada are limited, therefore the acquisition of this Permit by Cypress represents a milestone which will secure a majority of the Project’s future water requirements” stated Dr. Bill Willoughby, President and CEO of Cypress.
The company’s discovery of the massive resource made Clayton Valley a premium American source of lithium that has the potential to impact the supply of lithium for the fast-growing energy storage battery market.
“We’re in Nevada and we’re in a country that badly needs lithium. We would be the most environmentally friendly project, and the lowest acid consumer. We’re able to eliminate sulfuric acid in our process and that would make us an extremely environmentally friendly, large, inexpensive low cost producer in the heart of the United States.” said Cypress Development CEO Dr. Bill Willoughby.

The company is using environment-friendly mining alternatives through saltwater and hydrochloric acid instead of the traditional fresh water and sulfuric acid method. This significant proposal could mean Cypress will no longer compete for Nevada’s scarce fresh water supply for Nevada’s freshwater resources for project advancement when it comes time for mining.
In August 2020, Cypress released the results of its Pre-Feasibility report (“PFS”), which provided a positive snapshot of Clayton Valley’s prospective production scope using sulfuric acid. The Feasibility Study will use hydrochloric acid – a greener alternative to sulfuric acid). Probable reserves stand at 213 million tonnes at 1,129 ppm lithium, with an average annual production of 27,400 tonnes of lithium carbonate equivalent (LCE) and a mine life of over 40 years. The Net Present Value (NPV 8 percent) was at US$1.03 billion, and the after-tax internal rate of return (IRR) stood at 25.8 percent, using a base case price of lithium carbonate of US$9,500.
“This PFS is a major milestone for Cypress. These positive results take us closer to our goal of developing a potential world-class lithium deposit. Cypress’ land position and resources afford us the opportunity for a long-life project with low operating costs and potential to be a significant source of lithium for the United States,” Dr. Willoughby said.

Key Project
Clayton Valley Lithium Project
The 100 percent owned Clayton Valley lithium project spans 5,430 acres in southwest Nevada and sits immediately east of the Albemarle’s Silver Peak mine, North America’s only lithium brine operation. The asset hosts tremendous potential with Cypress’ discovery of a world-class resource of lithium-bearing claystone adjacent to the brine field to the east and south of Angel Island.
Lithium mineralization occurs on the property within montmorillonite clays throughout the sediments to a depth of at least 150 meters. Metallurgical testing has indicated low-cost processing possibilities through leaching with low acid consumption of 126 kg/t and high lithium recovery of over 85 percent lithium. This lithium claystone deposit’s unique large flat-lying nature allows for mining with a low strip ratio due to minimal overburden and no interbedded waste, which is hugely economically advantageous for Cypress.
2021 included the commissioning of the Clayton Valley lithium
project’s pilot plant, which completed a seven-day continuous run in December, after which Cypress renewed the lease. The company intends to use the data from the pilot plant towards the completion of the project’s
feasibility study. Cypress successfully received a
permit for water rights for Clayton Valley in the works, which pushes significant advancement in the 2022 seasons.
