Cypress Development

Unique Approach to Lithium Exploration in Nevada

This profile is part of a paid investor education campaign.*


Cypress Development Corp. (TSXV:CYP, FRA:C1Z1,OCTQB:CYDVF) is a junior resource company focused on lithium exploration in Nevada’s lithium-rich Clayton Valley, home to Albermarle’s (NYSE:ALB) Silver Peak Mine. Cypress Development’s flagship projects are the Dean and Glory Claystone/Brine projects located nearby the wells at the Silver Peak Mine and adjacent to Pure Energy Minerals’ (TSXV:PE) Clayton Valley South Project.

Nevada’s Clayton Valley is a rich jurisdiction for lithium exploration. The area is well served with maintained state highways that connect Silver Peak to the main road network in the state. As a whole, Nevada is considered to be the best mining jurisdiction in the US and ranked third worldwide by the Fraser Institute’s annual Survey of Mining Countries. Cypress’ projects also have access to electrical connection and water supply from the municipality of Silver Peak.

Lithium demand is on the rise due to the growth of the electric vehicle market. In Nevada, Tesla (NASDAQ:TSLA) has constructed a $5 billion Gigafactory, which is slated to increase demand for lithium in the state. Further large-scale lithium-ion battery factories are under construction around the world and are prompting increased production from companies already delivering on lithium, prompting companies like Albermarle to enter the Clayton Valley region.

Cypress’ Clayton Valley project is well positioned to help deliver lithium for the growing demand in the space. Following extensive exploration programs that spanned across 2016 through 2018, Cypress released a preliminary economic assessment (PEA) for the project in September 2018. Highlights from the PEA include an after-tax NPV (8 percent) of $1.45 billion and an IRR of 32.7 percent. The company anticipates an annual production rate of 24,000 tonnes of lithium carbonate over a 40-year mine life. Moving forward, the company will be conducting further infill drilling as part of an effort to complete a prefeasibility study (PFS).

Company Highlights

  • Flagship Clayton Valley lithium project located in the heart of the Clayton Valley lithium brine exploration area of Esmeralda County, Nevada—adjoining the Albemarle Silver Peak lithium mine.
  • Resource estimate of 3.84 million tonnes of lithium carbonate equivalent indicated and 5.126 million tonnes of lithium carbonate equivalent inferred.
  • PEA highlights of after-tax NPV (8 percent) of $1.45 billion and an IRR of 32.7 percent with 40-year mine life at annual production.
  • Metallurgical tests have shown the claystone is weak acid leachable with lithium extractions over 80% in 2 to 8 hours in agitated leach tests using sulfuric acid. Ongoing work for development of PFS expect in 1Q 2019.

Clayton Valley Dean Lithium Project

The Clayton Valley lithium project is located in the center of the Clayton Valley lithium exploration area, adjacent to Albemarle’s Silver Peak Mine property, North America’s only lithium brine operation. The project is made up of two claim blocks, Dean and Glory, which collectively measure 4,220 acres.

As the project area is located in an active lithium mining and exploration region, significant local infrastructure is already in place including state highway and road networks, electric power, water, exploration and operation services and skilled labor.

The land package includes Angel Island, which is an isolated exposure of highly deformed and metamorphosed rocks of Cambrian age akin to many others in the region. The rocks in these occurrences are surrounded by basin-fill evaporite rocks known as claystones. Cypress has uncovered that these claystones are lithium-bearing.

In May 2017, Cypress conducted a nine-hole core drill program on the Dean claim block. The drilling showed that all mineralized intercepts begin near the surface and the mineralized thickness is over 220 feet. The results outlined a lithium mineralized area of four kilometers by two kilometers and open in all directions. All nine holes encountered high values within claystone, ranging up to 1,790 ppm lithium and averaging 900 ppm lithium.

Between the end of 2017 and early 2018, Cypress conducted a 23-hole drilling program across the Dean and Glory claim packages. Results included 1,144 ppm lithium over 97 meters, 1,146 ppm lithium over 121 meters, and 1,134 ppm lithium over 107 meters. These results helped to expand mineralized zones on the property and led to the development of a maiden resource estimate in May 2018. This estimate was later updated as part of the PEA in September 2018.

Cypress Developments



In September 2018, Cypress released its PEA for the Clayton Valley lithium project based on a $13,000 per tonne price for lithium. Highlights from the report included the following:

  • After-tax NPV (eight percent) of $1.45 billion
  • After-tax IRR of 32.7 percent
  • Capital costs of $482 million over two years and payback period of 2.7 years
  • Pre-production and operating costs of $3,983 per tonne of lithium carbonate
  • Operating rate of 15,000 tonnes per day for 40-year mine life

The PEA also included the design for a tank leaching plant and a multi-stage thermal evaporation system for concentrating leach solution. The estimated acid plant capacity is 2,000 tonnes per day of sulfuric acid and the plant will be able to produce a lithium carbonate product at 99.5 percent purity. Net recovery of lithium throughout processing is estimated at 81.5% percent.

As part of the PEA, Cypress released an updated resource update for the property. This included an indicated resource of 3.84 million tonnes of lithium carbonate equivalent and an inferred resource of 5.126 million tonnes of lithium carbonate equivalent.

Moving forward

Following the publication of a PEA for the project, Cypress has announced that it is working on a prefeasibility study (PFS). This will include additional infill drilling to update resource categories and optimize the mine production schedule expected in 1Q 2019.
