Rockhopper Exploration Pushes Forward with Falklands Oil Project Amidst Argentinian Threats

Rockhopper Exploration has reaffirmed its commitment to developing the Sea Lion oil field off the Falkland Islands, asserting that the project remains on schedule despite vocal opposition and threats from Argentina.

The British company, which holds a 35% stake in the field with an Israeli partner owning the remaining 65%, is proceeding with its development plans. This comes after Argentinian President Javier Milei declared the Sea Lion oilfield a "clear and present danger" and threatened sanctions against companies involved in drilling activities in the disputed waters.

Milei stated, "If we do not act swiftly, in a few months they will have the material capacity to access the oil that lies underneath our sea." He further warned that if the United Kingdom does not cease "illegitimate exploitation" within two weeks, Argentina would escalate the matter to the International Tribunal for the Law of the Sea.

Despite these challenges, Rockhopper announced on Wednesday that it anticipates oil production to commence in the first quarter of 2028, with development drilling set to begin in early 2027. The initial phase of the development is estimated to cost approximately £1.6 billion.

Rockhopper's Chief Executive Samuel Moody described the recent period as "landmark," noting a "significant increase in the independent valuation of our interest in Sea Lion." He added, "Together with our recent capital raise, which leaves us fully funded to first oil, and the continued strong support of the UK and Falkland Islands Governments, we enter the second half of the year well positioned to deliver significant value to all stakeholders."

Owners of the Sea Lion field have previously expressed confidence that Argentina's rhetoric would not materially impact their project timeline. Independent assessments suggest the oil reserves in the Sea Lion field could be around 314 million barrels.

However, shares in Rockhopper experienced a decline, falling 8% to 59.20 pence on Wednesday afternoon, and have dropped by approximately a quarter over the past six months. These fluctuations occurred despite the company's assurances and the project's progress.
