2.8 km long magnetic anomaly discovered at Zaranou Gold licence, Cote d’Ivoire

IronRidge Resources has announced this morning that it has discovered a 2.8 km long magnetic anomaly, centralised within the zone of most intensive hard rock artisanal gold workings at the Zaranou gold licence in Côte d’Ivoire.


  • 2.8 km long by 800 m wide magnetic anomaly discovered within the Zaranou licence from recently completed airborne geophysical magnetics survey.
  • Magnetic anomaly occurs directly within a 16 km long by 200 - 500 m wide zone of intensive in-situ hard rock artisanal gold workings.
  • Additional smaller 800 - 200 m long magnetic anomalies occur along strike from the main anomaly and predominantly within the zone of hard rock artisanal workings.
  • 40 km long by 2.5 - 5 km wide alluvial gold mining corridor coincident with regional magnetic contact zone; a possible fault corridor.
  • Field mapping, soil sampling and litho-structural interpretation ongoing.
  • Drone survey on going and continues to generate high resolution imagery and topographic control to assist in exploration drilling programmes and baseline studies.

Commenting on the company’s latest progress, Len Kolff, Chief Operating Officer of IronRidge, said: “The discovery of the large 2.8 km long distinct magnetic anomaly is highly encouraging as it occurs centrally within the 16 km long zone of intensive hard rock artisanal gold mining.

“It represents a direct drill target that is blind at surface and provides a compelling geological and structural basis as to the location of intensive hard rock artisanal gold mining within the license area.

“The 2.8 km long distinct magnetic feature and associated smaller scale anomalies in and around the 16km long zone of hard rock artisanal mining suggests rock type variation and competency contrast interpreted as an intrusive body at depth; providing favourable structural trap sites for gold mineralisation to occur.

“Additionally, the airborne data shows a coincident magnetic feature along the 40 km long alluvial mining corridor, providing confidence in the definition of multi-ple additional gold targets.

“We are delighted with the discovery of the blind magnetic anomaly and we are currently planning a maiden 6500 m drill programme to test the mineralised structures using a combination of both air-core (AC) traverses and deeper target-ed reverse circulation (RC) drill holes. This drill programme is expected to com-mence in December 2019, and we look forward to updating the market on our progress and drilling results.”
