Cassius Mining Ltd., an Australian gold mining company, has escalated its legal battle with the Ghanaian government by filing a $277 million claim with the London Court of International Arbitration.

The company alleges breaches of contract and constitutional disputes surrounding its gold exploration project in the Talensi district of the Upper East Region.

The dispute stems from the non-renewal of Cassius Mining's prospecting license by the Ghanaian government in 2019.

The government argued that the license had not been properly ratified under the Ghanaian constitution, rendering it invalid.
