Zephyr Energy (AIM:ZPHR) is selling 1,837 acres of undeveloped, non‑core acreage in the Powder River Basin for aggregate gross proceeds of US$2.275 million, with an effective date of 1 June.
Zephyr, a technology‑led oil and gas company focused on responsible resource development in the Rocky Mountain region, says the acreage was part of the roughly 6,350 acres included in its US$7.3 million portfolio acquisition announced on 26 August 2025 and the disposals follow earlier sales from that package announced on 30 December 2025 and 24 March.
Both transactions are scheduled to complete, including payment to Zephyr, in the week commencing 15 June and the US$2.275 million is subject to customary closing adjustments.
Taken together with earlier disposals the original Acquisition has generated circa US$7.0 million of asset sales (comprising about US$5.8 million in cash proceeds and roughly US$1.2 million in near‑term plugging, abandonment and capital liability reductions) and produced US$1.7 million of revenue from the acquired production to 31 December 2025.
"Since the completion of the US$7.3 million Acquisition in August last year, we have generated over US$8.7 million in revenues, cash from acreage disposals and from other cost savings," Colin Harrington, Chief Executive, said.
Zephyr says it is evaluating options for the remaining undeveloped acreage and will provide further updates, with completion of these two disposals expected in the week commencing 15 June.
