Its key asset is the Tier-1 Bankan Gold Project. Bankan has a mineral resource estimate of 5.53Moz.

Liontown Ltd (ASX: LTR)

The Liontown share price roared 197% higher to close at $1.58 per share in 2025.

The ASX 300 lithium share surged on the back of rising lithium prices, which began rebounding midway through 2025.

The lithium carbonate price is at a two-year high, up 105% over the past 12 months.

Renewed global demand and low supply are powering this turn of events.

Lithium prices experienced dramatic price falls in 2023, followed by 18 months of stagnation in 2024 and the first half of 2025.

There is a greater demand for lithium now to power batteries and new infrastructure as part of the green energy transition.

EV manufacturing is also back on the rise, with EVs outselling traditional cars in China for the first time last October.

China is also trying to stabilise lithium prices by implementing policy measures to avoid overproduction.
