High-grade limestone confirmed at Oriole’s Wapouzé project

Oriole Resources PLC has announced promising findings from its initial diamond drilling program at the Wapouzé limestone project in northeastern Cameroon. The company conducted 21 exploratory holes, reaching depths of up to 47.50 meters, over a 1.2-kilometer stretch of outcropping metamorphosed limestone.

The drilling yielded remarkable results, with marble units discovered in every hole, indicating a high-grade resource. The majority of the samples contained over 50% calcium oxide (CaO) and less than 2% magnesium oxide (MgO), meeting stringent criteria for potential quarrying operations that supply material for the cement manufacturing industry.

Specific intersections reached impressive averages of 53.88% CaO and 0.88% MgO, and 53.42% CaO and 0.82% MgO, located at depths of 1.30 meters and 10.95 meters respectively. Oriole Resources holds 85% ownership of the Wapouzé project, situated roughly 100 kilometers northeast of Garoua and 20 kilometers north of its Bibemi gold project.

The discovery of CaO content exceeding 54% in certain intervals suggests the possibility of chemical lime manufacture. CEO Martin Rosser emphasized that the results demonstrate significant marble intervals with grades suitable for quarrying operations. The data will be utilized by an independent resource consultant to prepare a maiden JORC Mineral Resource Estimate and/or Exploration Target, which is expected to be published early in Q4-2026.

An Environmental and Social Impact Assessment is currently underway to facilitate the submission of an Exploitation Licence Application in Q4-2026. This report was AI-generated and reviewed by an editor.
