Kellyton Graphite Processing Plant Offers Domestic Refining Capabilities

Under construction with more than 50% of $245 million capital cost invested to date

Phase 1 optimization underway of currently expected 12,500mtpa battery-grade natural graphite; Phase 2 will increase planned capacity to a total of 50,000 mtpa

Phase 1 capacity nearly completely sold out by two offtake agreements

Qualification line capacity of ~1Mt for customers

Westwater's patented purification process has produced quality project samples which has led to our offtake contract success

Coosa Deposit Permitting Underway with 2026 Drilling Planned

Largest graphite deposit in the contiguous United States located in the graphite belt, 30 miles from Kellyton Processing Plant

~42,000 acres of mineral rights; 234 drill holes completed to date, representing less than 10% of the acreage

Exploration to date yields 2.3Mst of natural graphite at an average grade of 3.21%

2023 Initial Assessment indicates a 22-year mine life producing 99,000 st/yr of flotation concentrate grading 95% Cg

Feedstock supply agreement in place with non-Chinese supplier until Coosa operational

Key Priorities to Advance Coosa in 2026

Environmental Studies

Permits

Drilling

Necessary wildlife and environmental studies underway to support our permit applications

Westwater to file two key permits needed for the Coosa mine in 2026

Additional drilling planned for 2026; at 42,000 acres, existing 234 drill holes cover less than 10% of the mineral rights acreage
