Rockhopper shares plunge 16% as Argentina sanctions Sea Lion project in Malvinas

Rockhopper's share price fell over 16% on the London Stock Exchange after Argentina sanctioned the company for proceeding with its Sea Lion oil extraction plan in the Malvinas/Falkland Islands. The company had confirmed last week it would continue despite Argentine government measures. This marks an escalation in the sovereignty dispute, with direct market impact on the involved firm.
