Acquisition of Halliburton's 25% working interest in Alkaid/Phecda

Pantheon Resources plc ("Pantheon" or "the Company"), the AIM-quoted oil and gas exploration company with working interests in several conventional project areas in Tyler and Polk Counties, onshore East Texas, and onshore North Slope of Alaska, is pleased to provide shareholders with the following update:

Increased ownership in Alkaid/Phecda (Alaska) from 75% to 100%

Pantheon is pleased to report that it has executed a contractual agreement with Halliburton to acquire its 25% working interest in the six leases jointly held with Pantheon on the North Slope of Alaska. Under the agreement, which is subject to a customary approval process by the State of Alaska Department of Natural Resources, Halliburton will transfer to Pantheon their entire working interests in the leases in exchange for Pantheon accepting full responsibility for all future lease obligations.

As a result of this transaction Pantheon now holds 100% working interest in the 22,804 acres that make up the Alkaid/Phecda project, and 92% working interest in two additional adjacent leases comprising 11,367 gross acres. Upon the conclusion of this transaction, Pantheon will hold a 90-100% working interest in c.177,000 gross acres containing potential for 1.2 billion barrels of oil recoverable, located in close proximity to the North Slope of Alaska's major highway and pipeline infrastructure. In addition, Pantheon holds 10% working interest in the Winx acreage, covering an additional c.23,000 gross acres.

Jay Cheatham, CEO, said:

"This is great news for Pantheon shareholders. Alkaid is a tremendous success for our Company, and this transaction delivers us 100% ownership of the Alkaid/Phecda project which contains an estimated 900 million barrels of oil in place, and a P50 Technically Recoverable Resource estimated at 90-135 million barrels of oil based upon primary recovery assumptions of 10-15%. 100% ownership is important to our farm out discussions. The location of this project, sitting immediately below and adjacent to the Dalton Highway and Trans Alaskan Pipeline offers significant cost and timing advantages over other North Slope Projects, with the possibility of year round activity and targeted first production as early as 2020."

"Today's news follows the similarly important news only last month where we advised shareholders of the material advancements in the potential of our nearby Talitha Appraisal (Brookian) and Talitha Exploration (Kuparuk) projects, following a period of extensive analysis with the technical experts at eSeis."

"Our data room is open and we are working to find the right partner for the development of these significant projects."

Notes to Editors

Pantheon Resources plc is an AIM listed Oil & Gas exploration and production company with assets in East Texas and on the North Slope of Alaska, onshore USA.

The Group's stated objective is to create material value for its stakeholders through oil exploration, appraisal and development activities in high impact, highly prospective assets, in the USA; a highly established region for energy production with infrastructure, skilled personnel and low sovereign risk. All operations are onshore USA, with drilling costs an order of magnitude below that of offshore wells.

In East Texas, Pantheon held a 50% to 75% working interest ("WI") in several conventional prospects in Tyler & Polk Counties, in an area of abundant regional infrastructure, and in proximity to the prized Double A Wells Field. Pantheon has the ability for this working interest position to increase to 100% should the minority partner not be in a position to meet its pro rata share of future drilling and operating costs.

In Alaska, following its acquisition of the assets of Great Bear Petroleum in January 2019, Pantheon holds working interests ranging between 90% and 100% of prospects covered by circa 1,000 square miles of 3D seismic with P50 Technically Recoverable Resources estimated at over 1.2 billion barrels of oil.
