Wapouzé is an early-stage gold exploration project, covering highly prospective Neoproterozoic Pan-African greenstone belts in north-eastern Cameroon. The Company’s interest in the project is held through its 51%-owned subsidiary RMC Cameroon SARL.
Wapouzé (136 km2 ) is located 20 km north of Bibemi, in a similar geological setting. Reservoir Minerals conducted 1.5/ km2 stream sediment sampling between 2011 and 2015 and results (with 269 out of 573 samples analysed) included 14 samples >10ppb Au, 6 samples >25ppb Au and 3 samples >50ppb Au. The main anomalous structure follows the same orientation as at Bibemi and additional zones showing signs of mineralisation have been identified for follow-up.
In Q1-2019, Phase 1 systematic soil sampling was completed on a 400m by 100m grid to test the eastern portion of the licence for a total of 2,119 samples. Results, up to 531 ppb Au, identified two main zones of NE-trending mineralisation, associated with quartz veins hosted within a NE-trending package of sheared lithologies (amphibolite, diorite, marble and granodiorite) – the Bataol Zone (8km x 5km) in the north-east of the licence, which covers the previously identified stream sediment anomaly and the Bidzar Zone (2km x 4km) in the south-east of the licence.
At the Bataol Zone, multiple parallel >10 ppb Au anomalies have been defined, including an 8km-long by 0.2km-wide NE-trending anomaly. Multiple further anomalies have been defined in the Bidzar Zone, one of which (0.4km x 0.1km anomaly, >60 ppb Au) is supported by a 7.36 g/t Au selective rock-chip sample from an outcropping quartz vein.
Phase 2 infill soil sampling (200m x 100m grid) has recently been completed over main anomalies at the Bataol Zone in order to identify more discrete zones of higher-grade anomalism. Results for 639 soil samples returned a best grade of 210 ppb Au, with 3 samples reporting greater than 100 ppb Au, 45 samples >20 ppb Au and 123 samples >10 ppb Au. The soil results further confirm continuity of the >10 ppb gold-in-soil anomalies reported for Phase 1 soil sampling and have also defined more robust zones of higher-grade mineralisation within and independent of these zones. Of particular note is a >60 ppb Au anomaly that extends over an area of 1km by 300m within the previously-identified 2.8km anomaly in the centre of the Bataol Zone. This, and other areas of higher-grade gold-in-soil anomalism, appear to be related to nearby northeast-trending silicified and sheared metasedimentary unit.
Two short pilot trenches will commence shortly for a total of 200m, to test some of the key anomalies identified during the 2019 soil sampling campaigns. Sampling and detailed mapping will be undertaken to help understand the spatial-temporal relation between lithologies, alteration and structures. Subject to results, it is possible that the drill rig could be moved to test targets at Wapouzé following the programme at Bibemi.
BEIG3 Option Agreement
Under the terms of an Option Agreement signed in June 2018, the Company has earned an initial 51% of RMC Cameroon Sarl by funding US$1.56m of exploration over two years at the Bibemi and Wapouzé projects. Oriole is currently funding a maiden drilling programme at Bibemi that should see it earn a total 90% interest in RMC Cameroon Sarl, which also owns three licences within the 3,592km2 Central Cameroon licence pacakage.
