Inata – early VTEM results very encouraging
- Initial survey oriented over Inata
- Strong electro-magnetic anomaly
- Mineralisation along eastern flank of anomaly
- NE fabric intersections
- New targets:
- Poorly drilled zones to south & north
- Parallel zone to the east & west

- 16-kilometre long gold anomaly
- Artisanal workings
- 22 discrete soil anomalies
- Only 4 drilled to date
- Main zone – Dynamite
- 1,800 metres completed this year
- First batch sent to lab (14 May)
- Gabbro host
- 20 kilometres from Inata mill
- Potential to haul to Inata, or may
warrant new plant

Guinea – exploration schedule
16 R = resource model report
- Belahouro district is open and untested
- 1,660km2 covered by VTEM
- Systematic survey to define targets
- Inata “Area of Interest” drilling is a priority
- Souma obvious new resource
- Two quality targets in Guinea
- Tri-K Block is a multi-target district
- Porphyry host is important
- Sizeable target at Balandougou – 7 km
length up to 200 m wide
- Five more greenfields permits
