Notes to Editors

Zephyr Energy plc (AIM: ZPHR) (OTCQB: ZPHRF) is a technology-led oil and gas company focused on responsible resource development from carbon-neutral operations in the Rocky Mountain region of the United States.  The Company's mission is rooted in two core values: to be responsible stewards of its investors' capital, and to be responsible stewards of the environment in which it works.

Zephyr's flagship asset is an operated 45,000-acre leaseholding located in the Paradox Basin, Utah, 25,000 acres of which has been assessed by third party consultants Sproule International to hold, net to Zephyr, 2P reserves of 2.1 million barrels of oil equivalent ("mmboe"), 2C resources of 27 mmboe and 2U resources 203 mmboe. Following the successful initial production testing of the recently drilled and completed State 16-2LN-CC well, Zephyr has planned a three well drilling program - commencing in 2022 with the State 36-2 LNW-CC well - to further delineate the scale and value of the project.

In addition to its operated assets, the Company owns working interests in a broad portfolio of non-operated producing wells across the Williston Basin in North Dakota and Montana. 

The Williston portfolio currently consists of working-interests in over 200 modern horizontal wells which are expected to provide production of 1,550 - 1,750 barrels of oil equivalent per day, net to Zephyr, in 2023.  Cash flow from the Williston production will be used to fund the planned Paradox Basin development. In addition, the Board will consider further opportunistic value-accretive acquisitions.
