…commissions 2,440-line-kilometre airborne magnetic survey over Oko properties
(Kaieteur News) – Australian mining company El Dorado Goldfields, formerly Liberty Metals, is utilising the government’s mineral mapping programme to conduct a high-resolution magnetic survey over its Oko North and Oko South gold projects in Region Seven (Cuyuni-Mazaruni).
The Oko North and Oko South Gold projects, consist of a package of 40 medium-scale mining permits covering approximately 180 square kilometres (km²) in Guyana’s Oko gold district, Cuyuni-Mazaruni – an area where nine million ounces of gold have already been established by other foreign players.
In August 2026, El Dorado announced that it acquired 90% interest in the projects through an agreement with a private Guyanese vendor. In a statement this week, the company said it commissioned approximately 2,440 line-kilometres of airborne magnetic surveying across the two projects, with flight lines spaced 100 metres apart. The company noted that the survey is being conducted under the Government’s Industry Partners Programme, coordinated through the Guyana Mineral Mapping Programme (GMAPS).

According to El Dorado, the survey is intended to map shear zones, faults and geological contacts across the properties, targeting structures that control gold mineralisation. It disclosed too that flight planning has been completed and data acquisition is targeted for the current quarter.
Government is investing some $4 billion into the mineral mapping project. Global Venture Consulting, a private natural resource consulting firm based in Florida, USA was hired by the Ministry of Natural Resources in 2025 to conduct the mineral mapping exercise which will span four years. According to reports, Global Venture is working alongside two other industry specialists, AGF and Xcalibur Smart Mapping, to complete this assignment.
Moreover, the Australian company noted that under the arrangement, the survey data will be owned by El Dorado, while the Ministry of Natural Resources and the Guyana Geology and Mines Commission (GGMC) will retain a confidential archival copy.
The company’s Executive Chairman, Nicholas Katris, said, “Flying under the Government’s programme gives us a high-quality dataset quickly and cost-effectively. With soil sampling already underway, we are building the right dataset on ground directly along strike from a +9 million ounce system, and I look forward to updating shareholders as the work advances.”
Katris said too, “This Survey takes us another step towards converting our geology into maiden drill targets. Gold at Oko is structurally controlled, and across our ground that structure sits beneath cover and deep weathering. In a single campaign, we will map the shear zones, faults and contacts across both blocks which is exactly what the team needs to rank targets and get drilling.”
The airborne survey is expected to complement an ongoing soil geochemical programme involving approximately 5,000 samples across the two projects. The company explained that the magnetic and soil geochemical data would be integrated to identify and prioritise targets for trenching and maiden drilling.
Since acquiring its majority stake, the company has commenced exploration activities, including geological mapping, structural interpretation, rock-chip sampling and systematic soil geochemical work. Its maiden field programme identified extensive artisanal workings, quartz veining, basement shearing and hydrothermal alteration at Oko North.
The company changed its name from Liberty Metals to El Dorado Goldfields in October to reflect its focus on its Guyana gold projects.
