Blackthorn Resource Hits World Class 243m At 5% Copper At Kitumba

Blackthorn Resources (ASX: BTR) has intersected its best ever drill result at its wholly-owned Kitumba project in Zambia with infill drilling returning an intercept of 243 metres at 5% copper from 208 metres.

Another hole intersected 81 metres at 1% copper from 304 metres, in line with past results.

"We are delighted to report the best intercept at Kitumba to date with KITDD_027 returning a spectacular result of 243 metres at 5% copper, surpassing our previous best result in S36_038," managing director Scott Low said.

"Kitumba has yielded some world class grades, and we have great optimism about the economic potential for the Project."

He added the company looked forward to releasing the remainder of the assay results and an updated mineral resource estimated later in the year as Phase 7 drilling nears completion.

Infill drilling at Kitumba is now complete and the company is drilling an additional exploration hole to assess the potential for deep hypogene mineralisation as seen in S36-026 (41 metres at 2.31% copper from 569 metres) immediately to the north of Kitumba.

Kitumba is part of Blackthorn's wholly-owned Mumbwa Project in west central Zambia that covers 250 square kilometres and is being explored for Iron Oxide Copper Gold style mineralisation.

Kitumba Infill Drilling

The Phase 7 drilling program was designed to focus on the conversion of material in the Indicated category to Measured in the high grade core. A total of 10 infill holes and 3 geotechnical holes were planned.

The extension of holes S36-026 and S36-028 as well as a single angled hole from surface - KITDD_034 - were drilled to assess the potential for further deep hypogene mineralisation while geotechnical holes were designed to characterise the structural and engineering properties of material within the current extent of any potential future mining operations.

5,311 m of diamond drill core has been completed in Phase 7 to date, including all infill holes and the extensions on S36-026 and S36-028. Three rigs are currently drilling the geotechnical holes and the deep hypogene target.

KITDD_027 was drilled as an infill hole within the Kitumba mineral resource and 370 samples, including quality control samples, were submitted to the laboratory for analysis.

Besides the wide high grade intercept of 243 metres at 5% copper from 208 metres, KITDD_027 also intersected:

- 7 metres at 19.5% copper from 215 metres;
- 7 metres at 10.4% copper from 241 metres;
- 7 metres at 11.1% copper from 338 metres; and
- 8 metres at 10.5% copper from 357 metres.

KITDD_024 was drilled to test the eastern extent of the high-grade mineralised zone with the purpose of improving resource confidence.

A series of 318 samples, including quality control samples, were submitted to the laboratory for analysis.

This also intercepted 35 metres at 0.63% copper from 133 metres and 11 metres at 1.87% copper from 208 metres.

Kitumba

Kitumba has a current Indicated Resource of 87.6 million tonnes at 1.17% copper with the Pre-Feasibility Study expected to be released in the second half of 2013.

The study has identified underground mining, along with a combination of flotation, leaching and Solvent Extraction and Electro Winning (SXEW) processes as the preferred mining and treatment options.

As part of the underground mining assessment, sub-level open stoping and sub-level cave mining methods have been considered and are being evaluated.

Analysis

The blockbuster infill drilling result of 243 metres at 5% copper adds to the confidence that Blackthorn Resources has in converting the Indicated Resource at the world class Kitumba project into a Measured Resource. A Resource extension may also be included as part of this program.

Shares in the company could receive further kicks as more assay results as released in the lead up to the release of the Pre-Feasibility Study.
