Predictive Discovery (ASX: PDI) has uncovered broad widths of gold mineralisation at its Bongou Prospect in Burkina Faso including 10 metres at 7.4 grams per tonne (g/t), representing a new style of gold mineralisation.
This has increased the resource discovery potential within the broader Bonsiega Gold Project.
An eight hole, 1,263 metre reverse circulation drilling program completed in December has led to the discovery of broad intercepts of continuous gold mineralisation.
Two high grade intersections point to a high grade component to the mineralisation.
Notable intersections were:
- 10 metres at 7.4g/t gold from 47 metres;
- 102 metres at 1.1g/t gold from 4 metres, including 14 metres at 3g/t gold from 6 metres and 14 metres at 1.3g/t gold; and
- 70 metres at 1.2g/t gold from 62 metres to end of hole, including 18 metres at 1.8g/t gold from 82 metres, 10 metres at 1.6g/t gold from 109 metres and 7 metres at 2.1g/t gold.
A regional assessment shows that the mineralisation occurs on a major fault zone which extends for 43 kilometres on ground held or under application by Predictive.
Apart from Predictive’s recent drilling at Bongou, there has been no effective exploration of this fault zone.
Recognition of the Bongou gold mineralisation style has opened up a large new area for exploration within the Bonsiega Gold Project permit group.
Demonstrating the exploration upside, just 240 metres of strike has been tested so far, providing strong potential to extend Bongou and discover further Bongou-style mineralisation in the immediate vicinity and in separate targets further along strike.
The gold mineralisation is open to the southwest.
Further adding to the potential of the project, an interpreted pyritic alteration in a separate zone 150 metres to the west has been identified by ground geophysics.
Additionally, microgranite outcrops have been mapped 400 metres to the west, and two high priority target areas have been identified 4 kilometres and 10 kilometres northeast of Bongou.
The Bongou Prospect is located within the Laterite Hill Gold Field in Eastern Burkina Faso.
It covers artisanal workings forming an irregular open pit about 150 metres long and 50 metres wide.
Past exploration by Predictive included rock chip sampling, trenching and completion of one hole in 2012 which intersected 54 metres at 2.1g/t gold from 36 metres, including 20 metres at 4.8g/t gold.
Exploration plan
Predictive plans to return to Bongou with a reverse circulation drill rig in March to undertake infill drilling of the Bongou mineralisation and to explore for extensions to the known mineralisation in the immediate vicinity of the artisanal workings.
The company has identified three key target areas along the Bongou Fault Zone. The highest priority area is a 3 kilometre length of the structure immediately surrounding Bongou.
Geological mapping is already underway at this location.
Each of the target areas will be explored using induced polarisation surveys to identify zones of potential sulphides and rotary air blast drilling to follow up any geophysical anomalies.
Preliminary metallurgical test work will be carried out on mineralised reverse circulation chips from Bongou during the next two months.
