HyTerra seeks to tap white hydrogen potential with third well

• HyTerra selected the McCoy 1 well site based on geological understanding and in-house IP
• Murfin rig 116 will mobilise to McCoy 1 following a scheduled crew break
• Depending on maintenance requirements, it is expected to spud in early July

Special report: HyTerra has expanded drilling plans at the Nemaha project in Kansas under its year-long exploration program targeting natural (white) hydrogen, increasing the number of wells from two to three.

Based on results from Sue Duroche 3, the first well in this program, HyTerra (ASX:HYT) has decided to add a third well, McCoy 1, to this program.

McCoy 1 will be drilled ~9km east of Sue Duroche 3 on the same geological structure on the crest of the Nemaha Ridge.

HYT said the drilling of McCoy-1 marked a milestone for the company as it moved away from ‘twinning’ historical wells to now select well locations based on geological understanding and in-house IP.

The McCoy 1 drill site location was identified by interpretation of the company’s Xcalibur Airborne Gravity Gradiometry and Magnetic survey acquired in 2023, as well as legacy seismic data purchased and reprocessed in 2025.

HYT has been able to build geological models which can now be tested without having to first identify offset wells to twin, differentiating it from many peers.

Drilling plans

After a planned crew break, the Murfin Rig 116 will mobilise to McCoy 1 following some routine maintenance.

Depending on the time required to perform this work, McCoy 1 is expected to spud in early July.

HYT said having a break with the field crew avoided crew change out and maintained continuity across the entire exploration campaign allowing for operational efficiencies to be developed.

Background on Nemaha

Nemaha is at the centre of a major industrial and manufacturing hub between Kansas City and Wichita, placing it close to existing railways, roads and pipelines that connect to a long list of potential offtakers.

The recently completed Blythe 13-20 well – the second of the wells – was drilled to a total depth of 5,300ft mDKB (1,615m) on time, on budget and with no HSE incidents.

It sits about 1380m east of the historical Scott-1 well that reported hydrogen concentrations of up to 56%.

The real time mud gas log recorded hydrogen and helium gas readings at multiple intervals when drilling, indicating the presence of a hydrogen and helium play in this area.

Mud gas samples collected at surface are now at an independent laboratory, with results to be released to the market once received.

HyTerra joins lineup at Natural Hydrogen Conference

HYT continues to receive significant amounts of interest across print media and various geological groups globally.

The company has accepted the opportunity to speak at the upcoming Natural Hydrogen event being hosted by The Geological Society in London with presentation material to be made public prior to the event.
