• Excellent C1 (US$15.84) and AISC (US$20.32) in first 7 years

Modest CAPEX

• US$189M (or A$270M) capital cost estimate including 20% contingency and 15% EPCM
• Includes all processing and non processing infrastructure for the proposed stand-alone Lake Maitland operation, including entire processing facility with beneficiation plant and ability to produce both uranium & vanadium

Low operating cost estimates

• C1* Cash operating cost of US$15.84/lb U3O8 over the first 7 years
• C1* Cash operating cost of US$23.10/lb U3O8 over Life of Mine
• All In Sustaining Cost (AISC)# of US$20.32/lb U3O8 over the first 7 years
• All In Sustaining Cost (AISC)# of US$28.02/lb U3O8 over Life of Mine
• Very low C1 (US$15.84) and AISC (US$20.32) per lb U3O8 in first 7 years provide very strong margins

Mining & Production

• 17.5 year mine life (2.5 year payback period)
• Low average strip ratio of 1.17
• Process approximately 1.94Mt of ore per annum (front of beneficiation plant)
• Annual average production approximately 1.3Mlbs U3O8 (100% Indicated Resource) and 0.7Mlbs V2O5 (100% Inferred Resource) (refer to the Company’s release of 24 October 2022 for further details)
• Total production approximately 22.8Mlbs of U3O8 and 11.9Mlbs of V2O5 (refer to resource table for the Wiluna Uranium Project contained in Annexure A of the Company’s release of 24 October 2022 for further information as well as discussion on production schedule)

“The Board is pleased to commission the pilot plant design following on from the outstanding Scoping Study results for the Lake Maitland uranium deposit, which illustrate the quality and global significance of Toro’s uranium assets. The modest capital and operating costs result from many years of extensive research and development by Toro to optimise the processing flowsheet.

Lake Maitland represents a significant proportion of the Wiluna Uranium Project’s resources and highlight the transformational effect of the stand-alone Lake Maitland operation on the potential economics of the entire Wiluna Uranium Project.

Against a backdrop of a strengthening global uranium market, Toro is pleased to continue to advance Lake Maitland which is on track to be very competitive globally with a:

• 17.5 year mine life producing a total 22.8Mlbs U3O8 and 11.9 Mlbs V2O5
• short payback period of 2.5 years
• low C1 operating cost of US$15.84/lb U3O8 in years 1 to 7 when high grade uranium resource is being processed
• strong life of mine C1 operating cost of only US$23.10/lb U3O8
• low AISC cost of US$20.32/lb U3O8 in years 1 to 7 when high grade uranium resource is being processed
• strong life of mine AISC cost of only US$28.02/lb U3O8
• modest total CAPEX of US$140M plus 20% for contingency and 15% for EPCM
• total EBITDA of $1,768.6M
• total undiscounted cash flow of A$1,423M pre-tax

Toro remains very enthusiastic that we are on the precipice of a significant strengthening in uranium price and which can provide potential significantly higher returns than the financial returns published in the Lake Mailand Scoping Study, which assumed a US$70/lb U3O8 price, US$5.67/lb V2O5 price and a US$:A$0.70 exchange rate.

Toro is also confident it can further optimise these Scoping Study outcomes due to Lake Maitland’s close proximity to Toro’s 100% owned Centipede-Millipede and Lake Way uranium deposits within the Wiluna Uranium Project.

We are also buoyed by the clear opportunity that the potential integration of additional resources from these deposits affords Toro to significantly increase production at a Lake Maitland processing operation and, in particular, extend the processing of high-grade uranium resource well beyond the seventh year of production.”
