Predictive Discovery obtains 97% gold recoveries at growing Bira prospect

Predictive Discovery obtains 97% gold recoveries at growing Bira prospect

Tue May 15 2018


Gold recovery test work, RC drill results, and auger drill results have all been received.


Predictive Discovery Ltd (ASX:PDI) has received test work and drilling results from its Bira gold prospect within the Burkina Faso joint venture with Progress Minerals International.


Significantly, bottle roll tests on five reverse circulation (RC) drill intersection composites obtained calculated gold recoveries of at least 97%.


Secondly, final RC drill results from Bira featured 9 metres at 1.23 g/t gold from 8 metres depth and confirm known mineralisation to be 800 metres in length and open to the south.


Finally, results from auger drilling nearby to the Bira prospect have extended the strike length of the anomaly to 10 kilometres.


Predictive’s managing director Paul Roberts said: “The initial bottle roll tests suggest that good gold recoveries could be obtained from a future, conventional cyanide leaching circuit.


“The RC drilling has shown that the gold mineralisation is at least 800m long, open to the south and at depth.


“Directly south of the drilling, we now know there is a 10-kilometre long zone of power auger geochemical anomalies in which there is ample room to make a large gold discovery, which would add to the calculated resources and other gold mineralised zones known at and around the Bongou gold deposit.”

Final 13 holes of RC drill program received


The final 13 holes from the 49-hole, 5,129-metre RC drilling program have been received.


Drilling tested to a maximum vertical depth of 120 metres and explored a strike length of 900 metres along the known gold mineralised trend.


The new drilling has now expanded the known gold mineralised trend to a strike length of 800 metres.


More RC drilling is expected after the rainy season, estimated to commence in the December quarter.

Scout auger drilling program is ongoing


auger drilling over and to the south of the known gold mineralisation at Bira has been underway since December 2017.


Results have now been received for a further 812 holes totaling 4,147 metres and show that anomalous gold values now extend over at least 10 kilometres to the south and south-west of the RC drilled area.


This indicates substantial potential to discover more gold mineralisation along strike from the Bira prospect.


The power auger program is ongoing and will continue until the rainy season commences which is likely to be in late June or during July.


Drilling results from Cote D’Ivoire expected soon


Roberts added: “Elsewhere in Predictive’s large portfolio, work is advancing rapidly on multiple fronts, both in Cote D’Ivoire and Mali.


“We expect to have drilling results from Ferkessedougou North in Cote D’Ivoire to report in the next few weeks”
