Ariana completes due diligence on 1.3Moz Dokwe gold project in Zimbabwe

16 february 2024

Ariana Resources has completed its due-diligence programme on the 1.3 million ounces (Moz) Dokwe Gold Project in Zimbabwe, which is owned by Rockover Holdings.

It said 1222 metres of diamond drilling was completed for due diligence purposes, with two holes drilled at Dokwe North and two more at Dokwe Central.

"We are very pleased to report that our due-diligence drilling programme has now been completed on the feasibility-stage Dokwe Gold Project,” said Kerim Sener, Managing Director of Ariana.

“The programme was professionally conducted by the Rockover team, who worked collaboratively with our site team in Zimbabwe.”

He said preparation and analysis of the drill core will commence soon, following which these results will be compared to historical project data to confirm the understanding of the grade distribution and controls on gold mineralisation.

Sener said their confidence in the opportunity has grown based on their assessment of the project to date, including recent geological observations from drilling.

There are very few less than 1Moz gold projects globally with straightforward metallurgy, which are at a feasibility stage of development and have more than 95% of their JORC Mineral Resources in the Measured and Indicated categories, he said.
