Wia Gold Limited (ASX: WIA) has commenced a 9,000m aircore drilling programme on the Bouafle Sud permit in Côte d’Ivoire, West Africa.
Drilling is followig up positive results from auger drilling that have highlighted a series of wide and coherent +50ppb gold anomalies.
In addition, positive gold results from the auger program recently carried out on the Southern gold anomaly at the Mankono Project are now being infilled with further auger drilling.
“We are delighted with these latest results from our auger programme at the Bouaflé Sud permit that have led to the commencement of the current aircore drilling programme,” Chairman, Andrew Pardey, said.
“We now look forward to receiving these results and defining targets for future RC drilling.
“The Mankono Project is also progressing well, with infill auger drilling under way to strengthen the interpretation of the positive results returned to date.”
Auger drilling results at the Bouaflé Sud permit
The auger drilling programme that commenced in October 2021 on the Bouaflé Sud permit was completed in March 2022. The programme comprised 1,529 holes for a total of 8,418m drilled with the drill lines spaced between 200m to 800m and holes drilled every 25m along the lines. This drill spacing is based on interpretations from field work completed to date, including regolith and structural mapping and rock sampling and from review of the historical dataset.
The programme covers 7.5km strike on the bend of the main mineralised shear which had been highlighted by previous exploration, where the shear corridor was the focus of historical drilling. The most recent auger drilling programme has identified significant gold anomalism on the western concave side of the corridor, which until recently was host to artisanal mining activity.
The auger gold results returned a series of wide +50ppb anomalies, including a main central zone with an approximate 2km length on a north-south orientation. Several vein orientations have been measured in the field and correlate with the underlaying magnetic lineaments and the shape of the anomalies.
These, combined with the observed dips measured in the field towards the south-east to the east, led to the aircore drilling orientation towards the north-west. The lithologies were interpreted from the multielement assays returned from the auger samples. The different lithologies are sandwiched in parallel to the shear corridor, going from the east to the west, from the sediments, to a gabbro, then diorite and finally to a granite. The western side of the main gold anomaly is hosted by the gabbro, near the contact zone with the diorite.
The multi-purpose aircore drill rig has mobilised to the Project area and a 9,000m aircore drilling program is under way, with the first gold assays expected towards the end of May. A reverse circulation drilling programme (using the current drill rig performing the aircore drilling) will be prepared as the results of the aircore drilling are received.
