THE BOURSE WHISPERER: As the global mining community gathers for the Indaba conference in Africa, we check out a few ASX-listed companies operating around the continent.
BOSS RESOURCES (ASX: BOE)
Boss Resources (ASX: BOE) has reported a number of gold intercepts of notable grade and width from the Gariaga prospect within the company’s Gourma project in Burkina Faso.

The company said the results are from a maiden Aircore drilling program it carried out within the Fada N’Gourma Greenstone Belt in eastern Burkina Faso, which was designed to test for primary gold mineralisation beneath three soil anomalies within the Diabatou and Foutouri permits.
Intercepts returned from the maiden drilling program included:
– 14 metres at 2.1 grams per tonne gold from 1 metre;
– 3m at 11.3g/t gold from 5m;
– 7m at 2g/t gold from 19m;
– 7m at 1g/t gold from 29m;
– 3m at 2.3g/t gold from 45m;
– 2m at 3.2g/t gold from 29m; and
– 5m at 1.2g/t gold from 5m.
“The Gariaga results confirm the substantial strike extent of gold mineralisation in the Gariaga-Diabatou area and with further drilling we’re confident that the mineralisation will extend beneath the alluvial cover between the two prospects,” Boss Resources managing director Leigh Ryan said in the company’s announcement to the Australian Securities Exchange.
“With results from the Gourma Shear Zone at Bohongou and Foutouri still pending and extensive gold in soil anomalism throughout the Project now ready for drill testing things are looking very positive for Boss.”
PREDICTIVE DISCOVERY (ASX; PDI)
Predictive Discovery (ASX: PDI) released drilling results from four prospects tested in its December 2012 RC drilling program at the company’s Burkina Faso projects.
The program was aimed at five locations where Predictive had intersected high-gold grade mineralisation in previous sampling or drilling.

Having released results from the first prospect drilled, Bongou, earlier Predictive released drill results from 19 RC holes it had completed at the Madyabari, Tambiri South, Solna and Prospect 71 prospects.
Highlights from these results included:
– 2m at 26g/t gold from 70m, including 1m at 51g/t gold; and
– 2m at 12g/t gold from 12m, including 1m at 21g/t gold.
– 3m at 8.3g/t gold from 23m, including 1m at 21g/t gold; and
– 2m at 8.3g/t gold from 34m, including 1m at 14g/t gold.
Tambiri South prospect
– 4m at 6.1g/t gold from 83m, including 1m at 14g/t gold.
– 3m at 6.1g/t gold from 69m, including 1m at 14g/t gold.
“Our small December 2012 drilling program was aimed at testing high-grade drill targets within our Eastern Burkina Faso project for prioritisation of ongoing exploration activities,” Predictive Discovery managing director Paul Roberts said in the company’s ASX announcement.
“Encouraging grades were confirmed at all of the drilled prospects including Bongou, which we reported on last week.
“These results further enhance the pipeline of prospects and targets in PDI’s Eastern Burkina Faso project and offer two obvious targets for follow-up drilling.”
BASSARI RESOURCES (ASX: BSR)
Bassari Resources (ASX: BSR) informed the market it has been able to achieve high metallurgical recoveries from the company’s Makabingui gold project in Senegal, West Africa.
The company claimed recent test work from the expanded one million ounces of gold resource had confirmed the metallurgical response of the ore to be consistent with results from test work undertaken in April 2011.

The Makabingui gold project Mineral Resource was upgraded to one million ounces of gold in 11.9 million tonnes at 2.6g/t gold, at a cut-off of 0.5g/t gold in December 2012.
Additional metallurgical characterisation test work and comminution tests were commissioned to establish the Ball Mill Work Index of the ore.
The company said the objective of the test work is to assist in the conceptual forward planning for the potential development of the Makabingui gold project.
“The additional metallurgical results are very encouraging and support the test work carried out in 2011”, Bassari Resources managing director Jozsef Patarica said in the company’s ASX announcement.
“There is no evidence of refractory gold mineralisation with significant amounts of free gold evident, leading to a simple processing method incorporating a gravity circuit.
“These results, indicating free milling ore with a high gravity component, in addition to the high gold grade of 2.6 grams per tonne and near surface nature of the mineral resource (80 per cent above 200 metres below surface), augur well for the future development potential of the project.
“We have also carried out ore hardness test work to assist with the conceptual planning of the processing facility as we continue to grow the mineral resource and unlock the larger potential within the Makabingui project area.”
