In addition, the Alaska Gasline Development Corporation (AGDC) has released Wood Mackenzie's interim draft report: "Economic Viability Assessment and Economic Value of Alaska LNG project - Phase 1", in the past week. The report concluded that the proposed project provided higher economic benefit to the State of Alaska, that the alternative of importing LNG, and details a higher up front capex for the state given the cost of the pipeline, based on comparisons that assume the gasline would become operative in 2031.

Pantheon will update investors on progress towards funding of the FEED for the gasline in due course but continues its constructive engagement with AGDC to help bring the project to fruition.
