THE DRILL SERGEANT: Botswana-focused Discovery Metals has reported some encouraging results from recent exploration activity at its recently discovered Mango prospect.
Mango is situated within the company’s 100% owned Prospecting Licences located in the Kalahari Copper belt in north‐west Botswana.
The Mango prospect is located in the Boseto Zone and sits less than 25 kilometres from the company’s 100% owned Boseto copper project’s concentrator.
The Boseto copper project is currently undergoing construction with production scheduled to commence in the first half of 2012.
Discovery has planned production of approximately 36,000 tonnes of copper and more than one million ounces of silver per annum over an initial evaluated mine life of 15 years.
“Mango is an exciting new discovery within the vicinity of the Boseto copper project that will be explored further, with additional diamond, reverse circulation and RAB drilling planned over the next few months,” Discovery Metals managing director Brad Sampson said in the company’s announcement to the Australian Securities Exchange.
Six diamond drill holes have been completed over a strike length of approximately one kilometre at the north‐eastern end of Mango.
All drill holes intersected copper‐silver mineralisation between 30 metres and 140 metres below surface.
Best diamond drilling intercepts include:
- 13 metres at 1.8 per cent copper and 22 grams per tonne gold, vertical hole; and
- 11 m at 1.7% copper and 19 g/t gold, inclined hole.
Additional, RAB drilling carried out at Mango intersected oxide mineralisation in several holes with the best results of 10,450 parts per million copper in a hole eight kilometres south‐west of known mineralisation and 7,260ppm copper one kilometre south‐west of known mineralisation.
Discovery considers these RAB results demonstrate potential for copper‐silver mineralisation over eight kilometres of strike length to the south‐west of the current diamond drill holes at the Mango prospect.
The company has also commenced drilling close to the south‐west extremity of the Mango prospect, about 36km south‐west of the recently-drilled area.
Two diamond holes have been completed to date with geological logging confirming that one hole intersected copper‐silver mineralisation.
Discovery is still waiting on the assay results from this drilling.
A reverse circulation drill rig and a diamond core drill rig are currently working in this area.
“The mineralisation at the Mango prospect may offer potential for economic open pit or underground mining,” the company said in the announcement.
“Diamond, RC and RAB drilling program continue at Mango prospect and further results are anticipated in November 2011.”
