Block 9 (Melbana 30% interest) – onshore Cuba

In September 2015, Melbana executed the Cuba Block 9 Production Sharing Contract (PSC) with the Cuban national oil company Unión Cuba-Petróleo (CUPET). In May 2020, Melbana farmed out 70% of its interest in Block 9 PSC to Sonangol, the national oil company of Angola. The joint operation partners subsequently completed an initial two well exploration drilling program during the reporting period. This satisfied the work commitment for the current exploration sub period ending November 2023. The 2023 work program consists of the drilling of two appraisal wells. Melbana is required to meet 30% of the cost of this program and is forecasting its share to cost US$4.6 million for the Alameda-2 well and US$9.0 million for the Alameda-3 well over the next twelve month period
