Production
The project has a Mineral Resource estimate of 10.3 million tonnes at 1.03% Li2O. This is comprised of 6.1 million tonnes at 1.25% Li2O in the Indicated category and 4.1 million tonnes at 0.76% Li2O in the Inferred category. The project also has a maiden rubidium resource of 8.3 million tonnes at 0.27% Rb2O. An offtake agreement has been executed with LG Energy Solution for 25% of the first five years of production. The PEA highlights a potential for 207,000 tonnes per year of SC5.5 spodumene production.
Processing
The project will utilise a DMS (Dense Media Separation) concentrator to produce a 5.5% Spodumene Concentrate. A one-tonne spodumene concentrate sample from the Seymour project has undergone pilot testing at EcoPro Innovation's facility in South Korea, successfully producing battery-grade lithium hydroxide. This testing confirmed that Seymour concentrates are suitable for producing battery-grade lithium hydroxide using conventional processing techniques.
Equipment
The mining fleet outlined in the Preliminary Economic Assessment includes two 250-tonne excavators. One excavator will be used for bulk waste movement, while the other will focus on mining feed material. The project layout includes a processing plant, mining infrastructure, and water management infrastructure.

PotassiumSaltLithium
Overview
The Wendover mine, owned and operated by Intrepid Potash–Wendover, LLC, a subsidiary of Intrepid Potash, Inc., is located in Utah, United States. The facility is situated near the Nevada-Utah border on the western edge of the Great Salt Lake Desert, within the Bonneville Salt Flats. This is a solar evaporation mine, also referred to as a brine recovery mine or solar solution mine. The mining process involves extracting naturally occurring, potassium-rich brines from subsurface aquifers. The brine is collected from two main sources: a shallow-brine aquifer and a deeper aquifer. The solid salts are then harvested and transported to the processing facility.
Production
approximately 75,000 tons of potash per year
