The Bagoe Project covers a total area of 425km2. Initial geochemical sampling has defined two large scale, high-tenor gold-in-soil anomalies within the Bagoe Project area:
- Antoinette; and
Antoinette Gold Discovery
Exore has drilled over 10,000 metres of RC drilling at the Antoinette Central discovery across a defined strike strength of 850 metres of high-grade gold mineralisation. Drilling has been completed on 40-50m spacing to allow for resource definition. Drilling has shown excellent continuity of gold mineralisation along strike and down dip. Multiple zones remain open along strike, to the north and south, and at depth for further follow-up drilling.
Mineralisation at Antoinette Central is defined from surface and is deeply weathered with 50-60 metres of weathering.
Recent drilling results include:
- 5m @ 3.78g/t gold from 74m
- 7m @ 2.14g/t gold from 114m
- 9m @ 1.28g/t gold from 58m
- 4m @ 4.84g/t gold from 106m
- 2m @ 6.79g/t gold from 2m
- 4m @ 2.56g/t gold from 36m
- 25m @ 6.87g/t gold from 32m
- 15m @ 9.96g/t gold from 80m
- 11m @ 12.79g/t gold from 81m
- 11m @ 11.59g/t gold from 89m
- 21m @ 4.32g/t gold from 96m
- 23m @ 3.89g/t gold from 120m
- 12m @ 7.22g/t gold from 62m
- 8m @ 10.33g/t gold from 105m
- 5m @ 15.64g/t gold from 158m
- 18m @ 3.34g/t gold from 42m
High grade gold mineralisation at Antoinette Central is hosted by multiple lodes, with dip between vertical and -50 degrees to the south-east. The main zone of mineralisation is associated with a sheared package of carbonate-altered, fine grained sediments, with quartz veinlets and pyrite and arsenopyrite visible.
A first pass RC drilling program of just 10 exploration holes has been drilled in an area, nominally called Antoinette South, 900m along strike to the south of the Antoinette Central zone. Previous aircore drilling had identified shallow gold mineralisation over broad widths in oxide but the orientation of the mineralisation was not defined. Exore used the first ever exploration RC holes in this area to test a WNW strike orientation theory of the mineralisation, almost directly perpendicular to the mineralisation at Antoinette Central. All holes returned wide, well-mineralised gold intercepts. Multiple shallow lodes were intersected, associated with strong sericite-silica alteration and disseminated arsenopyrite and pyrite, within a granodioritic host rock. Mineralisation in multiple mineralised lodes has been identified over an area of over 350m strike length, still completely open in all directions. Further drilling is under way to better define the mineralisation in the south zone. In addition, the 900m of strike untested with bedrock drilling between the Central and South zones will be tested in the near future.
- 16m @ 1.97g/t gold from 139m
- 11m @ 2.39g/t gold from 37m
- 14m @ 2.06g/t gold from 30m
- 10m @ 1.83g/t gold from 62m
Exploration drilling has been conducted in an area of anomalous surface geochemistry and artisanal mine workings, 1,500m to the east of Central zone. This area is now being referred to as Antoinette East. Artisanal workings are traceable over >600m of strike, coincident with a highly sheared structure and quartz veining within a granite host rock. Three shallow RC holes were drilled as part of a reconnaissance program. All three holes returned gold mineralisation, with one very high-grade bedrock intercept of 5m @ 18.71 g/t gold.
A shallow reconnaissance AC drilling program in the wider Antoinette area to test surface geochemical anomalies has been completed. Wide, well mineralised in situ mineralisation was identified with an excellent AC drilling result of 30m @ 1.05g/t gold, which ended in mineralisation.
Veronique Permit Prospect
The Veronique Gold Discovery is located only 12 kilometres to the south of Antoinette. Veronique is defined by an 8-kilometre by 2.2-kilometre area of coherent and highly anomalous soil samples striking NNE, often grading >200ppb gold in soils with up to 1,320ppb gold. The anomaly remains open and is only limited by the extent of soil sampling.
A structural review of regional geophysics (airborne magnetics) in conjunction with the geochemical results interpretation has highlighted the similarities of the structural setting at Veronique with the nearby 4.2Moz Tongon gold mine operated by Barrick. Review of geophysics indicate that the same ENE-striking structures that appear to be key controls to Tongon are likely to extend to and potentially be key structural controls at Veronique, with mineralisation thought to be locally hosted by a linking NNE-striking structure.
First pass, reconnaissance AC drilling at Veronique by Exore has focussed on just the central zone of the large (>8km long) Veronique gold anomaly. The AC drilling was successful in intersecting shallow, high grade, in situ gold mineralisation including:
- 20m @ 6.46g/t gold from 8m
- 12m @ 7.00g/t gold from 16m
- 4m @ 7.58g/t gold from 20m
- 12m @ 3.12g/t gold from 36m
- 8m @ 2.23g/t gold from 48m
- 8m @ 4.30g/t gold from 12m
- 12m @ 3.63g/t gold from 4m
Incl. 4m @ 10.12g/t gold from 8m
- 8m @ 2.71g/t gold from 0m
- 1m @ 38.01 g/t gold from 28m (EOH)
There is no visible outcrop within the Veronique area and the area has no significant artisanal mining activity. AC drilling to date has correlated well with soil geochemistry confirming the effectiveness and validity of the 8km gold anomaly at Veronique. Drilling to date has been focussed on the central 1.6km of Veronique with highly anomalous gold geochemistry extending for a further 3km to the south and 3.5km to the north.
Shallow AC drilling to date indicates a WNW trend as the most likely orientation of gold mineralisation within the central 1.6km area of the >8km Veronique target.
Zones of mineralisation remain open in all directions. The WNW strike orientation opens up the possibility of multiple, sub-parallel, kilometre-scale mineralised lodes perpendicular to the 8km-long anomaly, >80% of which remains untested.
Initial geological observations indicate gold mineralisation is associated with zones of alteration and quartz veining within a granitoid unit, which is a similar geological setting to the recent 2.9Moz Doropo gold discovery made by Centamin plc, also in northern Cote d’Ivoire.
Bagoe Regional Geochemical Sampling
Much of the Bagoe Project area remains unexplored with surface sampling. Exore recently completed a regional geochemical soil sampling program at Bagoe by infilling areas of newly identified gold anomalism identified by its recent regional sampling program that has provided broad coverage across the entire Bagoe Project area on a 400 metre by 100 metre grid.
