Predictive Discovery's (ASX: PDI) new gold discoveries at the Bonsiega Project in Burkina Faso help progress the company towards a maiden JORC Resource, which is targeted for the September quarter of 2012.
At Prospect 71, reverse circulation drilling returned a high grade intercept of 4 metres at 7.1 grams per tonne (g/t) gold, highlighting gold in the area. This discovery is along strike from the near surface intersections of 4 metres at 15g/t gold and 2 metres at 7.5g/t gold.
Importantly the new gold intersection is supported by broader discoveries at the nearby Dave East prospect, which include:
- 26 metres at 2.7g/t gold from 22 metres;
- 28 metres at 1.6g/t gold from 30 metres; and
- 12 metres at 1.5g/t gold from 28 metres.
Mineralisation at Dave East remains open to the northeast and at depth.
Paul Roberts, managing director of Predictive Discovery, said the company's drilling programs in Burkina Faso are aimed at identifying the scale of potential gold mineralised systems and infilling the best prospects to advance towards a JORC Resource.
"Drilling on the Dave and Dave East Prospects within the Laterite Hill Grid has already identified a large mineralised system over a strike length of at least 4 kilometres including multiple lodes containing moderate gold grades and some higher grades at depth," Roberts said.
"Infill and extension drilling on just one of these lodes at Dave East shows that it extends for at least 500 metres with significant widths of gold mineralisation on each line."
Speaking on the Prospect 71 discovery, Roberts said the new assays confirm the presence of another higher grade lode to add to recent discoveries at the Tamboana and Koundi prospects.
"The higher gold grades in these zones balance the lower grades in "Dave East‐type" lodes and strengthen the probability of obtaining average grades over the whole Laterite Hill gold field above 2 grams per tonne gold," Roberts said.
Bonsiega covers about 100 kilometres of strike within the Samira Hill greenstone belt, which also hosts SEMAFO's (TSE: SMF) 2 million ounce Samira Hill gold mine in Niger.
The project is located within 100 kilometres of both the Samira Hill mine, and the producing Taparko-Bouroum Project in Burkina Faso, which has Proven and Probable Reserves of 8.85 million tonnes at 2.81g/t gold for 800,000 ounces of gold.
Predictive Discovery is continuing reverse circulation drilling on the Laterite Hill Grid, along with a power auger program testing 15 kilometres of greenstone strike to the southwest of the grid.
The company is planning preliminary metallurgical studies on representative samples of gold mineralisation.
