Glenfarne signs deal to lead development of Mat-Su, Donlin Gold gas pipeline

The company planning to develop the big Alaska LNG project with the state of Alaska, Glenfarne Alaska, has now signed on to help lead construction of the planned 313-mle natural gas pipeline from the Matanuska-Susitna Borough to the Donlin Gold project, a large gold mine being developed near the Kuskokwim River west of Mat-Su.

The agreement also provides for Glenfarne Alaska LNG, LLC, majority owner and developer of the proposed Alaska gas project, to supply up to 50 million cubic feet of natural gas per day and assist construction of the power plant needed to supply electricity to the mine.

Donlin Gold LLC, the developer of the mine, is owned by NOVAGOLD RESOURCES INC. and Paulson Advisers LLC. The companies signed a Letter of Intent, a form of preliminary agreement, for natural gas supply and the development of the infrastructure needed to deliver the gas and power the mine.

Glenfarne’s major focus is on the large project to build an 800-mile gas pipeline from the North Slope and a liquefied natural gas plant to export LNG but the company is involved in a variety of energy projects in the Lower 48 and Latin America. In Alaska, Glenfarne is working with Enstar Natural Gas Co. on a plan for a Cook Inlet terminal to import LNG for regional gas supplies.

This project could be done independently, if needed, if the large Alaska LNG project is delayed or not built. Similarly, Glenfarne could develop the Donlin Gold pipeline and power plant independent of the large North Slope project but delivering Cook Inlet gas, or even gas imported to Alaska as LNG, if needed.

Glenfarne Alaska LNG President Adam Prestidge said, “We have great confidence in the future success of Donlin following the significant investment by Paulson. Adding a foundational customer like Donlin Gold, one of the largest known undeveloped gold deposits in the world, to Alaska LNG provides significant volume discount benefits that will result in lower energy costs for Alaska consumers. As we continue to bring on more pipeline customers, the cost of gas for Alaskans will continue to go down.”

Located 10 miles north of the village of Crooked Creek, in the mid-Kuskokwim River region, Donlin Gold is one of the largest known undeveloped open-pit gold deposits today. Alaska stakeholders include the Calista Corporation (“Calista”) and The Kuskokwim Corporation (“TKC”), who own the mineral and surface estate at the Donlin Gold property and whose early leaders specifically selected these lands for their known gold-bearing potential.

NOVAGOLD is a minerals company focused on gold and the development of the Donlin Gold project in Alaska. Donlin Gold has approximately 39 million ounces of gold in the “Measured and Indicated” mineral resource categories, which means that it has been measured by drilling and thus carries a high confidence level. The estimated 39 million ounces measured and indicated is in 541 million tonnes of ore. (A “tonne” is a unit of measure of 2,200 pounds commonly used in Canada and the U.K., as well as in the minerals industry worldwide. The “ton” unit of measure also used in the U.S. is 2,000 pounds.)

John Paulson, President of Paulson, said: “A reliable, secure supply of economic natural gas from Alaska LNG has the potential to substantially enhance our ability to unlock value and upside potential in Donlin Gold. Glenfarne’s global energy experience is well suited to provide a long-term turnkey energy solution that helps advance this opportunity.”

Greg Lang, NOVAGOLD’s President and CEO, said: “As Donlin moves into what we hope to be the largest single gold mine in the United States, natural gas from Alaska LNG could offer significant benefits not only for the mine, but for the entire Southwestern Alaska region. We look forward to working with Glenfarne to unlock the value of both of these world-class Alaskan resources: Donlin Gold and Alaska LNG.”

For its part, Glenfarne is the owner and operator of 60 energy assets globally, with 11 offices in eight countries across four continents, including gas, solar, battery, hydro, and wind projects, and a North American LNG portfolio under development for 32.8 MTPA of LNG per year.

The company became lead developer of Alaska LNG in March 2025. Since then, Glenfarne has secured preliminary commercial commitments with leading LNG buyers in Japan, Korea, Taiwan, and Thailand for 11 MTPA of LNG, and strategic partnerships that also include Baker Hughes and POSCO International. Glenfarne owns 75% of Alaska LNG and the Alaska Gasline Development Corporation owns 25%.
