Argonaut Resources Identifies 1.9km Copper Target At Kavipopo, Lumwana West

Argonaut Resources (ASX: ARE) continues to build its inventory of drill targets at its Lumwana West copper project in Zambia with the identification of a 1.9 kilometre long target at Kavipopo.

Lumwana West is located in the Domes Region that is host to three mines that will soon have combined copper production of more than 1 million tonnes per annum.

The induced polarisation (NYSE:IP) chargeability, copper in soil and uranium radiometric anomaly has been ranked as a high priority drill target for the May 2014 drilling program.

This is expected to consist of eight holes totalling 2,400 metres at Kavipopo with the initial round testing the anomaly on three 400 METRES spaced traverses with drill holes spaced at 160 METRES along traverses.

The second round would seek to extend along strike and infill along traverses in the areas of copper mineralisation.

In addition, a revised Exploration Target for the Kavipopo target will be released next week to reflect the company's increased understanding of the geological and geophysical properties of basement hosted copper deposits in the Lumwana West area.

"The Kavipopo target continues to impress us on a technical level. The tight IP, soil and radiometric anomalies present an extremely compelling exploration target. Plus, Kavipopo has the scale to deliver significant tonnages," exploration director Lindsay Owler said.

"The Kavipopo IP anomaly is still open to the north and the east and the target is flanked by additional major anomalies at ZNS and LMW. Kavipopo is high priority drilling target for the 2014 drill program at Lumwana West."


The anomaly at Kavipopo was defined by the two primary methods used by the company to define drill targets at Lumwana West:

- Geochemical soil sampling in areas where soils are not prone to secondary chemical concentrating effects or major transportation from the soil's source; and
- IP chargeability anomalism at subsurface depths with reasonable potential for open-pit access to mineralisation.

When these are coincident and the basic geometric properties of the targeted mineralisation can be interpreted, then an effective drilling program can be planned and implemented.

Soil sampling had returned a peak copper in soil value of 556ppm with the remaining results defining an anomaly that is exactly coincident to the IP chargeability anomaly, indicating a strong correlation between datasets and steeply dipping interpreted mineralisation.

To top it off, the Kavipopo target features a strong uranium radiometric anomaly which is a feature of major copper deposits nearby at the Lumwana Mine.

The Kavipopo target is hosted in basement biotite-kyanite schists similar to the host schist at Argonaut's Nyungu deposit to the southwest. Mineralisation is assumed to be copper (+/- cobalt, gold and uranium) associated with basement shearing or thrusting.

The targeted mineralisation style at Kavipopo is Lumwana-style, shear-hosted, copper (+/- cobalt and gold) mineralisation in biotite-kyanite schists.

Lumwana West

Argonaut is building an inventory of copper deposits and large, high-priority drill targets at the Lumwana West Project in the Mwombezhi Dome, one of several domes in an area of the Copperbelt known as the 'Domes Region'.

The Domes Region is host to the new generation of Zambian Copperbelt mines including Barrick's (NYSE: ABX) Lumwana copper mine on the eastern lobe of the Mwombezhi Dome as well as First Quantum's (TSE: FM) Kansanshi Mine and Sentinel Project.

The Lumwana West joint venture allows Argonaut's 100% held subsidiary, Lumwana West Resources, to earn up to 90% of Mwombezhi Resources Ltd which holds the license area in question.

Exploration had recently identified the 2.5 kilometre long copper in soil West Mwombezi anomaly that returned very broad copper intersections including 196 metres at 0.45% copper from 69 metres.

The initial round would test the anomaly on three 400 metre spaced traverses with drill holes spaced at 160 metres along traverses.

The second round would seek to extend along strike and infill along traverses in the areas of copper mineralisation.

Given the size of the anomalies at West Mwombezhi, considerable drilling to extend the strike length is expected to be contemplated on confirmation of mineralisation of economic grade.
