A number of exploration targets for gold and tungsten have been identified in the broader ground holding at the Couflens Project based on historical and recent field campaigns, which returned high grade gold (up to 24.5 g/t) and tungsten (up to 8.25% WO3) from rock samples.
The Company commenced an airborne geophysics program to assist with the definition of exploration targets and to improve its understanding of regional geological structures, particularly focused on gold targets. The data collected from flights conducted to date is currently being processed and interpreted.
Following the completion of airborne geophysics programs, the Company will finalise its drill targeting and submit regional drill program applications to the authorities for approval.
The Company’s exploration efforts will be focused on the following areas:
Veronique Zone down plunge below existing mine development
Granodiorite contact around the Salau mine
Results from regional exploration programs
In 2016 a surface exploration program resulted in the identification of gold occurrences associated with three main east-west trending fault structures within the Couflens licence area.
In September 2017, a follow-up surface exploration program was completed which was primarily focussed on identifying extensions to the gold occurrences along these fault structures. The majority of samples were collected on the margins of the granodiorite intrusion (Fourque granodiorite) near the historical Salau tungsten mine.
The exploration program included detailed geological and structural mapping, rock chip sampling of outcrop, and input of the data into an ArcGIS software package to facilitate data integration and interpretation.
A total of 222 select rock chip samples were collected during the field campaign and subsequently submitted for gold and multi-element (including tungsten) analysis.
Assay results from the gold samples were received first and were reported to the market on 29 November 2017, demonstrating widespread gold occurrences with grades of up to 24.5 g/t. For full results please click here.
Assay results from all other elements, including tungsten, were subsequently received and were reported to the market on 5 February 2018. The tungsten assay results confirmed the presence of widespread, outcropping, high grade skarn mineralisation around the margins of the Fourque granodiorite.
Where the skarns are observed to be intersected by east-west trending fault structures/shear zones, the mineralisation is typically sulphide-rich (mainly massive pyrrhotite, chalcopyrite and sphalerite) and contains substantially higher values of tungsten (up to 8.25% WO3) and gold (up to 24.5 g/t) from rock samples.
