Core Viewpoint - Sintana Energy Inc has been identified as a high-upside investment opportunity with a target price of 62p, following a 12-month extension to its offshore Namibia licence, which is expected to facilitate a farm-out process [1][2]. Group 1: Licence Extension and Market Potential - The 12-month licence extension for PEL 87 allows the Pancontinental-led partnership additional time to market the Orange Basin asset and secure a partner for exploration drilling [2]. - A number of groups are reportedly advancing technical due diligence, with drilling of an exploration well anticipated later this year [2]. Group 2: Stake and Resource Estimates - Sintana holds an indirect 7.35% stake in PEL 87 through its interest in InterOil/Custos and is expected to be carried through the exploration well [3]. - The licence is supported by modern 3D seismic coverage over 6,593 km², with estimated gross recoverable 2U prospective resources exceeding 2 billion barrels, including the largest prospect, Oryx, estimated at 1.09 billion barrels, and Hyrax at 733 million barrels [3]. Group 3: Valuation and Risk Assessment - Cavendish attributes 1.2p per share of its 62.1p sum-of-the-parts valuation to PEL 87 on a risked basis, with an unrisked value of 44p per share for Sintana's interest [4]. - The valuation incorporates Pancontinental's geological chance of success and a commercial risk factor related to securing a farm-in partner, with the extension providing more time to enhance the project's risk profile [4].
