Australian firm taps $4B Govt. mineral mapping programme for Oko gold hunt

(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).
