Villeta Update

ATOME (AIM: ATOM), provides an update further to the previous announcements regarding the power purchase agreement ("PPA") at the Villeta Project, Paraguay.

ATOME confirms that discussions continue with the relevant counterparties in Paraguay on the specific terms of the PPA with the Government of Paraguay having expressly indicated that it wants to see the Project succeed.

All relevant stakeholders, including the project's international commercial partners and lenders, the latter being IDB Invest - the private sector arm of the Inter-American Development Bank Group consisting of 48 country members, IFC - the private sector arm of the World Bank Group, the European Investment Bank, FMO - the Dutch Development Bank and the Global Climate Fund, managed by the World Bank, continue to be supportive of ATOME and the strategic Villeta Project.

It is generally recognised that the Villeta low-carbon fertiliser project is of major strategic importance to Paraguay which will place the country on the world map of fertiliser production as well as creating thousands of jobs in the process and providing the people of Paraguay with support for its own food supply amidst the country's growing agricultural sector.

Unless there are any material developments in the meantime, ATOME expects to provide a further update to the market in the first part of August.
