Blackthorn hits further high-grade copper at Mumbwa

/in /by

THE DRILL SREGEANT: Blackthorn Resources has extended its run of good news with the reporting of further high-grade copper intersections from a Phase 5 drilling program being conducted at the company’s Mumbwa copper-gold project in Zambia.

The latest highlights from the drilling program have come from drill hole S36-038 and include:

223 metres at 4.67 per cent copper between 188 metres and 411m, including:

–    23m at 11.28 per cent copper between 205m and 228m;

–    23m at 9.06 per cent copper between 231m and 254m; and

–    36m at 8.84 per cent copper between 260m and 296m.

Drill hole S36-038 is a redrill of S36-033, which the company was originally forced to abandon incomplete at a depth of 463.20m due to drilling rods becoming stuck in the hole.

Drill hole S36-038 is located approximately 5m from the S36-033 collar and was drilled vertically to an end of hole depth of 653.55m.

Drill hole S36-38 was drilled vertically, with Balckthorn targeting the known higher-grade core of the Kitumba mineral resource area, with the primary purpose of completing the abandoned drill hole S36-033.

The company was also seeking to validate the high-grade intersections in that drill hole it had reported in February 2012.

“We are very pleased that these results provide further evidence of the presence of an exceptionally high-grade core in the Kitumba area,” Blackthorn Resources managing director Scott Lowe said in the company’s announcement to the Australian Securities Exchange.

“The intersections are of similar width and grade at similar depth to those reported in S36-033.

“Drilling is continuing, with the holes yet to be reported from this phase being “step out” holes designed to test for an extension of the Kitumba mineralisation zone.

“The exploration work undertaken at Kitumba since regaining control of the project has delivered some excellent results and our understanding of mineralisation continues to improve.

“We look forward to completing the drilling in coming weeks and undertaking a recalculation of the mineral resource to be announced mid-year.”
