Blackthorn Resources Intersects Copper At Mumbwa Satellite Targets

Blackthorn Resources (ASX: BTR) has intersected hypogene sulphides including 12 metres at 0.55% copper from 307 metres and 17 metres at 0.42% copper from 399 metres at the Mumbwa Project in Zambia.

The assays were returned from the three Orion 3D induced polarisation target drill holes that were drilled immediately after completion of the Phase 7 infill program.

Targets were based on detailed interpretation work which highlighted areas separate from Kitumba that presented IP anomalies hosted in prospective lithologies.

KITDD_040 has returned primary sulphide mineralisation along the northwest trending Mumbwa Fault Zone within feldspar porphyry syenite and metasedimentary units.

These results will be reviewed in the context of the regional geological interpretation and existing datasets including surface geochemistry and airborne geophysical data to generate and prioritise targets for future exploration.

"We are pleased to be able to report the final results from our three Orion 3D IP target holes," chief operating officer Tony De Santis said.

"With KITDD_040 containing primary sulphide mineralisation, we plan to look more closely at the area around the "Mutoya" magnetic high (which includes the Kakozhi prospect) and prioritise our efforts for the next exploration season."

KITDD_038 was drilled on an azimuth of 090, inclined 60 degrees to a depth of 401.6 metres targeting a chargeability high associated with an interpreted structure trending north-west along the western side of Kitumba.

KITDD_039 was drilled on an azimuth of 270, inclined 65 degrees to a depth of 476.9 metres that tested a chargeability high associated with the Mumbwa Fault.

KITDD_040 was drilled on an azimuth of 090, inclined 60 degrees to a depth of 423.2 metres targeting a chargeability high associated with the Mumbwa Fault.


Blackthorn Resources had earlier this month updated Resources at the Kitumba deposit at its wholly-owned Mumbwa Project in Zambia by 25% to 34.7 million tonnes grading 2.29% copper at a 1% cut-off.

This includes a Measured Resource of 10.4Mt at 2.93%, or 306,000 tonnes of contained copper.
