Critical Resources Eyes Lithium Growth at Corona Within Mavis Lake Corridor (ASX:CRR)

Highlights

• New exploration program targets underexplored lithium corridor
• Corona field could extend Mavis Lake into a multi-deposit district
• Focus on building next wave of drill-ready targets

Critical Resources is advancing lithium exploration at the Corona field, aiming to expand Mavis Lake into a multi-deposit district and build a pipeline of drill targets supporting long-term growth.

Critical Resources Ltd (ASX:CRR) is preparing to advance its lithium exploration strategy in Canada, with a new field program targeting the Corona Pegmatite Field near its flagship Mavis Lake project. While not part of a major benchmark like the ASX 200, the company operates within the broader lithium and critical minerals space that remains closely tied to global battery demand trends.

What is the focus of the new exploration program?

Where is the opportunity?

The Corona Pegmatite Field sits within a prospective lithium corridor in Ontario, located just north of the existing Mavis Lake resource. The upcoming program will target a stretch of lithium-bearing pegmatites that has seen limited historical exploration.

Early indications suggest the presence of wide pegmatite bodies within the same geological setting that hosts Mavis Lake, reinforcing the potential for additional discoveries.

What work will be carried out?

The exploration campaign will include:

• Surface mapping and geological interpretation
• Prospecting and geochemical sampling
• Identification of drill-ready targets

This work is designed to build a pipeline of targets for future drilling, with initial results expected later in the year.

How does this fit into the Mavis Lake strategy?

Is Mavis Lake evolving beyond a single deposit?

The company is aiming to transform Mavis Lake from a standalone asset into a broader lithium district. The Corona field is seen as a key component of this strategy, potentially adding scale and depth to the project.

Other nearby targets, including Gullwing and several regional prospects, are also being advanced in parallel to support long-term resource growth.

Why is this important?

Developing multiple deposits within a single corridor can:

• Improve project scalability
• Enhance resource continuity
• Support long-term development planning

This approach reduces reliance on a single deposit and strengthens the overall project narrative.

What are the key drivers behind this exploration push?

What makes the area prospective?

The region hosts lithium–caesium–tantalum (LCT) pegmatites, a geological setting commonly associated with spodumene-bearing lithium deposits. Historical datasets, including geochemical analysis and geophysical surveys, provide a strong foundation for targeting.

However, limited surface exposure due to overburden means systematic exploration is required to unlock the full potential.

How is data being used?

Critical Resources is integrating multiple datasets, including:

• Lithogeochemistry
• Pegmatite fractionation analysis
• Aeromagnetic surveys

This combined approach is expected to refine targeting and improve the chances of identifying economically viable mineralisation.

What does this mean for the broader investment narrative?

Opportunities

• Potential to expand Mavis Lake into a district-scale lithium asset
• Growing exposure to battery materials supply chains
• Multiple exploration targets providing ongoing news flow

Risks

• Exploration uncertainty and early-stage nature of targets
• Dependence on successful drilling outcomes
• Broader lithium market volatility

Broader takeaway

Critical Resources is positioning itself to move beyond a single-asset story by targeting new lithium growth within the Corona field. If exploration success follows, Mavis Lake could evolve into a larger, multi-deposit lithium district, strengthening the company’s long-term development pathway.
