Zefiro subsidiary Plants & Goodwin, based in Bradford, Pennsylvania since 1970, continues to advance its nationwide orphan well plugging partnership with the Well Done Foundation, including cleanup work now underway in the Deep Fork Wildlife Refuge (Oklahoma).

The partnership's local impact includes the 2025 plugging of a Bradford-area orphan well known as "Warrant 3489 Johnston & Mathews #1."

This progress was recently featured on the front page of The Bradford Era, the local newspaper serving the McKean County area since 1875.

Bradford, Pennsylvania--(Newsfile Corp. - August 11, 2026) - ZEFIRO METHANE CORP. (Cboe Canada: ZEFI) (FSE: Y6B) (OTCQB: ZEFIF) (the "Company", "Zefiro", or "ZEFI") is pleased to provide an update on the continued progress of its orphan well plugging partnership with the Well Done Foundation, including recent recognition of its local impact in Bradford, Pennsylvania, home to Zefiro subsidiary Plants & Goodwin since 1970.

This progress was recently featured on the front page of The Bradford Era , a newspaper for the McKean County area in Pennsylvania, adding to Zefiro's recent press coverage from outlets that include Energies Media . The article in The Bradford Era was penned by Sara Furlong, who is the newspaper's Managing Editor.

The teaming agreement between Zefiro and the Well Done Foundation was officially announced by both organizations in July. The Well Done Foundation currently operates in 18 U.S. states, and the teaming agreement with Zefiro is expected to further expand this reach. Earlier this year, Zefiro added operating capabilities in five additional states, bringing its operating territory to 13 total states with current or recent operations.

One example of this local impact is an orphan well in Bradford, Pennsylvania that was plugged last year through a collaboration between the Well Done Foundation and Zefiro subsidiary Plants & Goodwin. For years, local residents in the area of Schaming Drive and Seaward Avenue in Bradford were not concerned by what appeared to be just a rusty piece of metal with an orange cone over it. However, when Well Done Foundation Chairman Curtis Shuck visited the site in 2021, he removed a cap over the well and found it was leaking 50% methane.

Zefiro subsidiary Plants & Goodwin is based in Bradford, Pennsylvania, where its orphan well plugging work has drawn local and national attention

After consulting with the Pennsylvania Department of Environmental Protection and engaging Zefiro subsidiary Plants & Goodwin, the orphan well known as Warrant 3489 Johnston & Mathews #1 was ultimately plugged in November of 2025. Actor Jason Priestly, known for his role as Brandon Walsh in Beverly Hills 90210 , visited the site after the well was plugged in his capacity as a brand ambassador for the Well Done Foundation. Additionally, the British Broadcasting Corp. ("BBC") sent a crew to interview the family whose residence is situated on the lot where the orphan well was found.

The article in The Bradford Era also references several of Zefiro's recent accomplishments including:

Plugging a 15,000-foot-deep gas well in Custer County, Oklahoma ( Press Release );

Generating 92,956 metric tons of verified carbon dioxide-equivalent reductions from the Custer County project, marking the first certified carbon offsets generated from an orphan well under the American Carbon Registry's orphan well methodology;

Securing a three-year USD $19.6 million Construction Manager at Risk contract with the Ohio Department of Natural Resources ( Press Release );

Plugging more than 75 state-funded orphan wells across Ohio and Pennsylvania in 2025; and

Completing USD $850,000 in methane-monitoring work for the West Virginia Department of Environmental Protection through the U.S. Environmental Protection Agency's Methane Emissions Reduction Program ("MERP").

Zefiro Chief Executive Officer Catherine Flax commented, "We are thrilled to have received front-page newspaper coverage from the local press in Bradford, Pennsylvania, which is the home base of Zefiro's operations. Although plugging orphaned wells is often thought of as an issue that is specific to the oil/gas industry, it is not uncommon for these wells to directly impact residential areas in regions such as Western Pennsylvania. Because of this, it is of interest to the general public that these wells are being plugged as they can impact property values for homeowners while also posing a safety concern for local residents and families. Zefiro's partnership with the Well Done Foundation has been transformational for bringing our work into the public eye, and we are excited to keep ramping up our efforts as part of initiatives nationwide to plug orphaned oil and gas wells."
