MACUSANI URANIUM PROJECT

A Green Energy Enabler

Through our Macusani uranium project, our goal is to advance one of the world’s largest and lowest cost undeveloped uranium projects to help meet the world’s need for green, clean and efficient energy.

Project Highlights

Strong Project Economics ^1

Strong Project Economics ^1

• NPV: US$603M | IRR: 40.6% | 1.8 years capital payback (post-tax)
• Large scale: proposed production averaging over ~6 Mlbs U₃O₈ per year over a 10 year mine life
• PEA mine plan resources: ~70 Mlbs U₃O₈ at 289 ppm
• Low Cost: ~US$17/lb LoM cash production cost, ~US$300M initial capital
• At ~US$35/lb (near term price): NPV: ~US$235M

Uranium Resources ^2

Control of All Defined Uranium Resources in Emerging Uranium District

• Measured & Indicated: 52.9 Mlbs U₃O₈ (248 ppm) (75ppm U cut-off)
• Inferred: 72.1 Mlbs U₃O₈ (251 ppm) (75ppm U cut-off)
• Growth Potential: 47+ targets around existing defined deposit

Near Surface + Leach Kinetics

• Five near surface deposits included in the PEA mine plan
• Hosted in porous volcanic rock → strong recoveries and low regent consumption

Excellent Infrastructure

• Roads, inexpensive power, water, etc. proximal to project

Path to Permitting

• Environmental Impact Assessment commencing
• Government regulations on Uranium Transport + Export
• Uranium mining and processing regulations in place
  • Transport and export regulations in accordance with IAEA standards pending

Macusani Uranium Project Economics¹

Uranium Price Sensitivities:(After-tax NPV 8%)

• At US$65/lb:

~$965M

• At US$35/lb:

~$235M

• NVP break-even price: US$25.66/lb
• Relatively less sensitive to operating and capital costs
• Project highly leveraged to uranium price
• Resilient to downside, scalable to upside

American Lithium has acquired Plateau Energy Metals as of May 11, 2021.

Macusani Uranium Project Growth

Existing Deposits

• Targeted drilling in and around existing defined deposits
• Infill drilling in inferred deposits outside current PEA mine plan

Kihitian Complex

• Tantamaco South East - targets in between Tantmaco and Quebrada Blanca deposits
• Untested post-land consolidation of extensions to mineralized manto horizon

Regional Targeting

• +47 additional targets property wide

Macusani Uranium Opportunities

Processing

Tank leach option work to be advanced

Potential for better recoveries & shorter leach cycle

• Mid-90’s in early tests vs. 88% in PEA

Capex/opex vs. recoveries trade off

Pre-Concentration

Potential economic improvement with size/screen sorting

• 85% uranium contained in 50% of mass in fine fraction

Potential for less material handling, higher processed grades, reduced processing throughput and smaller plant footprint

Scalability

Phased expansion, smaller initial capex options to be reviewed

• 2 to 6 Mlbs U₃O₈ annual production ranges considered previously
• Review + engineering work in consideration

Growth

Near Mine Plan Resources

• Existing deposits/zones outside of current PEA to be followed up on
• Potential for more than 50 million lbs of U₃O₈ to be included in the PEA

Project Resilience

High grade only option to be revisited in more detail

Optimization work on current PEA mine plan

Exploration

85% of exploration land package undrilled - untested targets for early follow-up

Additional target generation

Tax Model

Currently modeled as 3% NSR in PEA

Royalties are now sliding scale based on operating margin and applied to net income

Permitting clarity

Peru participating in ongoing discussions with Peruvian regulators around the legal framework for handling and exporting of radioactive material

Ministry focused on permitting clarity in near-term

Support

Presidential level support to implement permitting framework for Peru’s first uranium mine

Local communities in support, Baseline Study accepted, commencing EIA
