Primary Hydrogen Enters Nova Scotia’s Cumberland Basin Natural Hydrogen District With Staking Of The Northumberland Project
Primary Hydrogen Corp has staked the Northumberland Natural Hydrogen Project in Cumberland County, Nova Scotia, securing two exploration licences covering 72 claims and approximately 1,166 hectares along the northern margin of the Cumberland Basin.
The project is located between Northport and Pugwash, fronting the Northumberland Strait, and directly adjoins ground associated with Kavenex Energy and Denver-based Koloma Inc. This places Primary Hydrogen in one of North America’s emerging natural hydrogen exploration districts.
The company said the Northumberland project was acquired through map staking via Nova Scotia’s NovaROC system. The property has road access through the Route 6 corridor and covers a coastal position along the northern margin of the Cumberland Basin.
Interest in the area has increased following hydrogen readings reported from nearby exploration projects. Quebec Innovative Materials Corp. reported a peak field reading of 16.0% hydrogen at its Bennett Hill project in June 2026, while its West-Advocate drilling reported a peak mud-gas reading of 10.77% hydrogen in May. At West-Advocate, the company reported five readings of at least 5% hydrogen over a 69-metre interval.
First Atlas Resources has also reported soil-gas hydrogen values of up to 1,652 parts per million on the northern margin of the basin near Springhill.
Primary noted that these results are from nearby properties and have not been independently verified by the company. They are being provided for regional geological context only and do not establish the presence of natural hydrogen on the Northumberland licences.
The company believes the geological setting of the Cumberland Basin warrants further investigation. The basin contains thick Carboniferous sedimentary sequences overlying Windsor Group evaporites, while salt structures such as the Pugwash salt structure locally deform the sedimentary section and could potentially provide sealing structures for migrating gases.
Primary also considers reactivated basin-margin faults along the northern flank of the basin to be potential migration pathways for gases from depth. These geological characteristics form part of the exploration model being applied across the district.
Primary’s initial work programme will consist of data compilation, structural interpretation and a soil-gas orientation survey during the current field season. The results will be used to identify potential targets for further exploration.
The company has stressed that no drilling for natural hydrogen has been undertaken on the Northumberland Project and no hydrogen occurrence has been documented there to date. Natural hydrogen exploration remains an emerging field, with exploration methods and geological models continuing to develop.
Nova Scotia is simultaneously establishing a dedicated regulatory framework for natural hydrogen. Legislation passed in April 2026 created the Subsurface Energy Resource Extraction Act, which is intended to regulate natural hydrogen, helium, geothermal and carbon-storage projects. The legislation had not yet been proclaimed in force at the time of the announcement, with regulations still under development.
The staking also places Primary alongside a growing group of companies pursuing natural hydrogen in the Cumberland Basin. Immediately south of the Northumberland Project is the licence block associated with Kavenex Energy’s partnership with Koloma, a Denver-based natural hydrogen company that has raised more than US$400 million from investors including Breakthrough Energy Ventures, Khosla Ventures, Mitsubishi Heavy Industries and United Airlines.
Primary Hydrogen CEO David Jackson said the company sees the Cumberland Basin’s recent exploration results and increasing competition for land as an opportunity to establish an early position in the district.
The immediate focus for Primary will now be on understanding the property’s geology and determining whether surface-gas or structural indicators justify further exploration. Any future drilling or development will depend on the results of this initial work.
Overall, the announcement represents an early-stage natural hydrogen exploration entry rather than a confirmed discovery. Primary has secured a 1,166-hectare position next to active exploration ground in a basin where nearby projects have reported significant hydrogen readings, and the company will now begin work to determine whether similar geological and hydrogen potential exists on its Northumberland licences.
