Zefiro partners with Well Done Foundation on well-plugging expansion in US

Zefiro has secured an initial purchase order for plugging ten wells in Oklahoma for the Well Done Foundation, an acclaimed non-profit founded in 2019 that has eliminated over five million metric tons of CO2 equivalent emissions by remediating orphan oil/gas wells. As an established vendor for the Well Done Foundation, this strategic partnership will prioritize Zefiro as a plug-and-abandonment service provider for projects being led by WDF in the 13 U.S. states where Zefiro has operating capabilities. As part of the teaming agreement, Zefiro and the Well Done Foundation will share a yard in Okmulgee, Oklahoma - which further establishes Zefiro's presence in one of America's major hubs for oil and gas production.

Bradford, Pennsylvania--(Newsfile Corp. - July 14, 2026) - ZEFIRO METHANE CORP. (Cboe Canada: ZEFI) (FSE: Y6B) (OTCQB: ZEFIF) (the "Company", "Zefiro", or "ZEFI") is pleased to announce a teaming agreement with the Well Done Foundation ("WDF") in which Zefiro will carry out plugging operations for orphan oil and gas wells under projects led by WDF, whose footprint consists of 18 U.S. states. To start operations under the teaming agreement, Zefiro and WDF have executed an initial purchase order for the remediation of ten wells in the Deep Fork National Wildlife Refuge (located approximately 35 miles from Tulsa), with a further 20 wells expected to be assigned to Zefiro for plugging in 2027 as part of WDF's contract with the U.S. Fish and Wildlife Service . As a result of this teaming agreement, Zefiro will have a sustained operating presence in the State of Oklahoma.

By virtue of this presence, Zefiro's management expects that the Company will be well-positioned to bid on additional projects in Oklahoma, which is a key oil/gas state as the sixth-largest producer of both marketed natural gas and crude oil in the United States. Zefiro and WDF have previously collaborated on well-remediation projects, including a notable project called Bear Run 001 . Located in Erie County, Pennsylvania, Bear Run 001 was an undocumented orphan natural gas well in a mobile home park just 15 feet from a residence.

Zefiro subsidiary Plants & Goodwin, Inc. ("P&G") successfully plugged this well on February 2, 2023, which resulted in 23,746 metric tons of CO2 equivalent emissions being reduced (equal to the annual emissions of approximately 5,162 automobiles). Okmulgee, Oklahoma: The Pine 2A Well is Pictured Above in the Deep Fork National Wildlife Refuge. This Well is One of 35 Already Plugged in the Refuge by the Well Done Foundation.

In August of 2023, the Bear Run 001 well that was plugged by Zefiro subsidiary P&G was featured by the Smithsonian Channel on its How Did They Fix That? series (Season 2, Episode 5 - "Abandoned Oil Wells" ).

Key information and photographs from Bear Run 001 can be found on its Project Profile on the Well Done Foundation's website: Bear Run 001 Project Profile The Well Done Foundation was established in 2019 by former oil executive Curtis Shuck, and the organization has plugged over 120 wells across the United States with more than five million tons of CO2 equivalent emissions eliminated. In 2022, the Well Done Foundation and Mr. Shuck were profiled by Business Insider in a 13-minute segment which has more than 1.5 million views on YouTube: https://www.youtube.com/watch?v=8EjkgPzVWjE Zefiro Chief Executive Officer Catherine Flax commented, "We are delighted to be working with the Well Done Foundation, an esteemed and highly respected leader in recent efforts to clean up America's orphaned wells. Our management team expects that this teaming agreement with WDF will impart many strategic advantages for us between a steady book of business in new markets, the formation of an ongoing presence in Oklahoma, and performing work for yet another U.S. government agency.

The initial allocation of ten wells in the Deep Fork National Wildlife Refuge will be undertaken throughout the remainder of 2026, and we anticipate that the second tranche of wells in this project will keep us busy well into 2027, including during the winter months. It is an honor to work with Curtis Shuck and the Well Done Foundation, and we are enthusiastic to have this opportunity to join forces as the nationwide cleanup of orphan wells continues to build momentum." Well Done Foundation's Chairman Curtis Shuck said, "This partnership with Zefiro will be very impactful as we at WDF seek to accelerate efforts in plugging orphan wells throughout the country. Not only does Zefiro have top-tier expertise in plug-and-abandonment for orphan oil/gas wells, they are also among the three largest firms in the U.S. in terms of dedicated operations in this category.

In 2025, the Well Done Foundation was engaged by the U.S. Fish and Wildlife Service to plug more than 110 oil and gas wells on two wildlife refuge sites - and we are thrilled to have Zefiro's support behind us for our ongoing work in Oklahoma, and for many more projects to come. This is the beginning of a very exciting partnership, and on behalf of the WDF team we are looking forward to continuing our work with Zefiro." About Zefiro Methane Corp.
