THE DRILL SERGEANT: Mt Isa Metals has received high-grade gold assay results from phase 2 reverse circulation (RC) drilling at the company’s Bantou gold prospect located in south‐west Burkina Faso.
“Drilling completed to date at the Bantou prospect has now defined near‐surface gold mineralisation over an approximate 600 metre strike length,” Mt Isa Metals said in its ASX announcement.
“The new drilling results have also confirmed gold mineralisation in a second structure located approximately 30 metres in the hangingwall (to the west of) the Bantou Main Lode.
“Gold mineralisation at the Bantou prospect is open in all directions – i.e. along strike to the north and south, and at depth below the limit of current drilling.”
The Bantou gold prospect lies within the company’s Kongolokoro project area and was originally identified by a zone of shallow northeast‐trending artisanal gold workings that extend over an approximate 1,000m strike length.
MT Isa completed an initial scout drilling program at Bantou in late 2010, which recorded near‐surface gold mineralisation.
This included intersections of:
- 8 metres at 80.32 grams per tonne gold from 36m; and
- 5m at 6.12g/t gold from 60m.
The second phase of drilling recently completed was carried out to follow up encouraging drill results achieved by the company in its first drilling phase.
According to the company the phase 2 drilling results include significant near‐surface gold intersections in multiple structures.
Drill intersections recorded on the Main Lode structure, carried out directly below the main trend of artisanal workings, include:
- 4 metres at 6.03 grams per tonne gold from 66 metres;
- 9m at 16.79g/t gold from 91m;
- 16m at 10.20g/t gold from 17m; and
- 5m at 6.55g/t gold from 109m.
Drill intersections recorded on the Bantou Hangingwall Structure include:
- 6 metres at 7.35 grams per tonne gold from 44 metres;
- 6m at 5.27g/t gold from 8m;
- 11m at 2.59g/t gold from 7m; and
- 11m at 2.63g/t gold from 48m.
“Mineralisation on both the Main Lode and Hangingwall structures is open along strike to the north and south of current drilling,” Mt Isa said.
“Mineralisation is also open at depth below the limit of current drilling – approximately 100 metres vertical depth.”
MT Isa said it intends to conduct additional RC drilling of the Bantou prospect in the forthcoming field season.
