Invictus Energy has commenced moving Exalo Rig 202 from the Mukuyu-2 wellsite to its Musuma-1 exploration site in the Cabora Bassa Basin, bringing the company closer to testing a new hydrocarbon prospect outside its existing Mukuyu gas-condensate discovery area, Mining Zimbabwe can report.

The Australian Stock Exchange-listed explorer confirmed that the relocation follows the completion and formal acceptance of the Musuma-1 wellpad, associated civil works and access roads by drilling contractor Exalo Drilling S.A.
The rig move will be followed by rig-up operations, outstanding maintenance work and final operational readiness checks before drilling begins. Invictus remains on track to spud Musuma-1 in November 2026.
Musuma-1 is targeting an estimated gross mean unrisked prospective resource of approximately 1.2 trillion cubic feet (Tcf) of gas and 73 million barrels of condensate. These figures represent potential resources that have not yet been discovered, and drilling will be required to determine whether hydrocarbons are present.
The well is considered a significant test of the wider Cabora Bassa Basin because it will target a separate play type on the basin’s Eastern Margin, beyond the Mukuyu discovery area.
Invictus has identified several prospects in the eastern part of its licence through its 2023 seismic survey, known as CB23. The Musuma-1 well is intended to test the resource potential of this area and determine whether the company’s exploration success can extend beyond Mukuyu.
Invictus Managing Director Scott Macmillan said the start of the rig relocation marked another milestone in preparations for the next exploration campaign.
“The commencement of the Rig 202 move to Musuma-1 marks another important milestone as we move closer to drilling our next high-impact exploration well,” Macmillan said.
He said the company would now focus on rig-up, remaining maintenance and operational readiness activities ahead of drilling.
The move follows several months of preparations, including securing drilling and well-services arrangements and completing the infrastructure required to accommodate the rig and support operations at the new site.
Building on Mukuyu Exploration
Musuma-1 builds on Invictus Energy’s exploration programme in the Cabora Bassa Basin, where the company has drilled the Mukuyu-1 and Mukuyu-2 wells and reported a gas-condensate discovery.
The earlier drilling programme has helped inform the company’s geological understanding of the basin and its subsequent exploration targeting. Musuma-1 will test a different area, providing further information on the extent of the basin’s hydrocarbon potential.
The distinction is important for Zimbabwe’s emerging oil and gas exploration sector. While the Mukuyu results have established a basis for continued evaluation, Musuma-1 will test whether another material accumulation exists elsewhere within Invictus’s acreage.
A successful exploration result would still require further evaluation and appraisal to establish the scale, recoverability and commercial viability of any hydrocarbons discovered.
Invictus holds approximately 360,000 hectares in the Cabora Bassa Basin, with its portfolio comprising the Mukuyu gas-condensate discovery and multiple additional exploration prospects.
The company has also advanced its regulatory framework through a Petroleum Production Sharing Agreement with the Government of Zimbabwe, providing a framework for the project’s exploration and potential future development.
For Zimbabwe, the broader significance of the programme lies in whether continued exploration can establish commercially viable domestic hydrocarbon resources capable of supporting future energy and industrial development. Any such benefits would depend on successful drilling, appraisal, development investment and the establishment of the necessary production and delivery infrastructure.
Invictus said there had been no material changes to its prospective resource estimates since the updated estimates released on September 3, 2024.
The immediate focus is now on completing the rig move and final preparations before the planned November drilling campaign.
