DEFENSE METALS COMPLETES SUCCESSFUL PHASE I PILOT PLANT WORK

Defense Metals Corp. has completed phase I of its hydrometallurgical pilot plant at SGS Lakefield.

John Goode, Consulting Metallurgist to Defense Metals and who attended the pilot plant, commented: "This first fully integrated pilot plant demonstration of the proposed Wicheeda hydrometallurgical process delivered exactly what was required of it. We have confirmed the general workability of the process, optimized certain design parameters, and identified areas that will be improved ahead of the Phase II pilot plant. The SGS Lakefield team did an excellent job of construction and operation of the circuit, and their efforts are much appreciated."

The main objective of Phase I of the pilot plant was to test the flowsheet for operability and identify any changes that might be required before a longer test campaign. During the five days of continuous operation, the parameters for the various unit operations were varied slightly to allow optimization of the circuit ahead of the Phase II pilot plant run scheduled for late-April 2023.

Assays are still being received and evaluation of the results has not yet been finalized. However, to date it can be reported that the extraction of Pr (praseodymium) and Nd (neodymium) from the acid bake calcine was in excess of 90%, the impurity removal circuits were very efficient, and reagent regeneration and water recirculation were effective. Minor changes will be made to the circuit ahead of Phase II and an alternative product precipitant will be used.

Methodology

The fully integrated Pilot Plant included sulphuric acid baking, water leaching, three stages of impurity removal, rare earth precipitation, magnesia regeneration and recycling, and process water recycle. The plant ran continuously and without interruption for 24 h/day over a total run time of 110 hours. Operations were handled by a total of ten SGS technicians and metallurgists on each of two shifts managed by senior day-shift staff.

About the Wicheeda REE Property

Defense Metals 100% owned, 4,262-hectare (~10,532-acre) Wicheeda Light REE property is located approximately 80 km northeast of the city of Prince George, British Columbia; population 77,000. The Wicheeda REE Project is readily accessible by all-weather gravel roads and is near infrastructure, including hydro power transmission lines and gas pipelines. The nearby Canadian National Railway and major highways allow easy access to the port facilities at Prince Rupert, the closest major North American port to Asia.

The 2021 Wicheeda REE Project Preliminary Economic Assessment technical report ("PEA") outlined a robust after-tax net present value (NPV@8%) of $517 million and an 18% IRR1. This PEA contemplated an open pit mining operation with a 1.75:1 (waste:mill feed) strip ratio providing a 1.8 Mtpa ("million tonnes per year") mill throughput producing an average of 25,423 tonnes REO annually over a 16 year mine life. A Phase 1 initial pit strip ratio of 0.63:1 (waste:mill feed) would yield rapid access to higher grade surface mineralization in year 1 and payback of $440 million initial capital within 5 years.
