HyTerra Prepares to Drill McCoy 1 Well in Kansas, Expands Nemaha Program
HyTerra Limited (ASX: HYT) has provided an operational update for its Nemaha Project in Kansas, USA, announcing the mobilization of Murfin Rig 116 to the McCoy 1 drill site. The well is expected to spud later this week.
McCoy 1 is a key milestone for HyTerra as it transitions from twinning historical wells to selecting drill sites based on advanced geological analysis and proprietary intellectual property. The site was chosen following encouraging results from the Sue Duroche 3 well, which lies on the same geological structure along the Nemaha Ridge. Site selection leveraged the company’s 2023 airborne gravity gradiometry and magnetic survey data, combined with reprocessed seismic data from 2025.
In addition, HyTerra has deployed a workover rig to its Blythe 13-20 well to prepare it as an appraisal well. Downhole monitoring equipment is currently being installed to gather subsurface data for future testing programs.
The Nemaha Project, which now includes three wells scheduled for drilling between April and July 2025, is funded in part by Fortescue Future Industries Technologies Pty Ltd. HyTerra remains focused on exploring geologic hydrogen and helium resources near major industrial hubs in the U.S.

ASX RELEASE
Operational Update – Nemaha Project
Highlights
Murfin rig 116 has mobilised to McCoy 1 and is rigging up to drill, well is on track to spud later this week.
McCoy 1 was selected to drill based on encouraging results from Sue Duroche 3, located on the same geological structure on the Nemaha Ridge.
McCoy 1 is a milestone for the Company as it moves away from "twinning” historical wells to data-driven well locations based on geological understanding and inhouse intellectual property.
Workover rig has arrived at Blythe 13-20 to convert it to an appraisal well with installation of downhole monitoring equipment taking place this week.
HyTerra Ltd (ASX:HYT) has increased the number of wells it will drill between April and July 2025 at the Nemaha Project in Kansas, USA from two to three. This exploration program funding is sourced from an investment in the Company by Fortescue Future Industries Technologies Pty Ltd.
McCoy 1 spudding this week
Murfin Rig 116 has arrived at McCoy 1 location and is in the process of rigging up. McCoy 1 well will spud in later this week. McCoy 1 is located on the same geological structure on the Nemaha Ridge as Sue Duroche 3, with the decision to drill based on encouraging results seen in Sue Duroche 3.
The drilling of McCoy 1 is a milestone for the Company as it moves away from "twinning” historical wells to a data-driven process for selecting well locations based on geological understanding and inhouse IP. McCoy 1 drill site location was identified by interpretation of the Company’s Xcalibur Airborne Gravity Gradiometry and Magnetic survey acquired in 2023, and legacy seismic data purchased and reprocessed in 2025.
Blythe 13-20 conversion to appraisal well
The workover rig arrived at Blythe 13-20 on Monday and will begin the process of cleaning the well up and installing downhole monitoring equipment to provide information to assist in the design of an initial testing program planned to be after all the wells have been drilled and the subsurface data has been analysed.
