·     Zones of elevated mineralisation up to 0.19% Cobalt and 1.31% Copper

·     Surface soil anomalism indicates a potential mineralised system of scale extending to the north for 5km over a strike of 2km

·     Mineralisation open to the north and west of Kalaba, mainly from or near surface

·     25 Diamond Drilling and 21 Reverse Circulation holes completed with more assay results expected in the near-term

Nick von Schirnding, Executive Chairman of Arc Minerals commented:

 

"The results of our drilling programme to date show a continuous band of mineralization, from surface in the south gently dipping to the north, the dimensions of which have to date exceeded all our initial internal expectations.  With several intersections now well over 100m in thickness and the average thickness ranging between 60m to 80m, our Kalaba Prospect is beginning to show all the hallmarks of a typical large deposit in the Domes region in north west Zambia. Further, we are seeing elevated grades averaging up to 1.3% copper and 0.19% cobalt within this band of mineralisation - with continuous cobalt dissemination throughout the mineralised zones.

With a pipeline of completed drill holes and three rigs turning on-site day and night we expect to be reporting drill results from the Zamsort project on a frequent basis from now with a view to reporting a maiden JORC Resource for Zamsort in the near future.

In the meantime, the pilot plant is on schedule and under budget and commissioning is expected to commence in Q4 of this year.  We are at a very exciting crossroads for the Company and following on from our recently announced premium fundraise we have a healthy balance sheet to progress exploration and development work at Zamsort. I look forward to updating shareholders on further developments in the near term."

Notes:    

1)    Reported intervals are downhole widths, which are similar to the true widths.

2)   Reported intervals are calculated for zones assaying > 0.2% Copper or 0.02% Cobalt and containing less than 3 meters of internal waste.

3)   The Copper equivalent values are estimated using current metal prices of $6000/t copper and $60,000/t cobalt and are presented for ease of interval comparison only. Metallurgical factors are assumed to be 100% although the recovery factors for the respective metals may vary significantly.

4)    The Copper equivalent values may differ slightly due to rounding.

Drilling Programme

 

These diamond and reverse circulation drill holes have been collared so that they test the strike and down dip extensions to the mineralisation that is exposed on surface at the Kalaba open pit.

 

The mineralisation is hosted by a dolomitic unit which crops out on surface in the south and dips in a northerly direction below an overlying schistose unit. The mineralisation at present has been tested down dip for 600m and along strike for 500m and remains open to the north and west, bounded by the Kalaba river to the east and south.

 

An 11,000-metre drilling programme (4,400m of diamond and 6,600m of Reverse Circulation drilling) is currently underway at the Kalaba prospect. Part of the drilling programme is designed with the view to create a shallow oxide resource for the Commercial Scale Demonstration Plant ("CSD plant") that is currently in the process of being completed. The principal aim is to establish a Maiden Mineral Resource Estimate at the Kalaba prospect.

 

To date, 25 diamond holes have been completed totalling over 3,750 meters and 21 RC holes for over 1,900 meters. Assays for the rest of the holes drilled expected during the coming weeks and months.

 

The spatial location of the samples is derived using GPS collar survey pickups. True widths have not been determined as the level of detail required to calculate accurate true widths is not yet available, as a result down hole widths have been reported. However true widths are not expected to differ significantly from the down hole widths reported.

 

 

 

Quality Assurance/Quality Control (QA/QC)

 

The core from the diamond core was sampled at up to 1.5m metre intervals with the split core (PQ - ¼ core; HQ - ½ core) bagged and sent to SGS Inspection Service Ltd in Kalulushi, Zambia, an ISO accredited laboratory for assaying.

 

The samples from the reverse circulation drill program were collected at one metre intervals following which they are weighed. Samples were split at the drill site using a riffle splitter with the split sample bagged separately and reject inserted back in the original sample bag. The split RC sample of approximately 2kg was sent to SGS Inspection Service Ltd in Kalulushi, Zambia, an ISO accredited laboratory for assaying.

 

The samples were sorted, dried, crushed and pulped before final chemical analysis using ICP-OES methods. Standards, blanks and duplicates were inserted regularly in the sample stream and checks were done for Copper and Cobalt.

Technical Glossary

Assay	the laboratory test conducted to determine the proportion of a mineral within a rock or other material.
Diamond Drilling	a drilling method in which penetration is achieved through abrasive cutting by rotation of a diamond encrusted drill bit. This drilling method enables the collection of tubes of intact rock (core)
Dip	a line directed down the steepest axis of a planar structure including a planar ore body or zone of mineralization. The dip has a measurable direction and inclination from the horizontal
Grade	the proportion of a mineral within a rock or other material which for gold is usually measured in g/t
JORC Resource	Resource estimated according to the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, as published by the Joint Ore Reserves Committee of The Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia
M	metre, a unit of length as per the International System of Units
Mineralisation	the process or processes by which a mineral is introduced into a rock, resulting in a valuable or potentially valuable deposit.  It is a general term, incorporating various types; e.g., fissure filling, impregnation, and replacement
Mineral Resource	Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill-holes which may be limited or of uncertain quality and reliability
QA/QC	Quality Control and Quality Assurance, a set of defined  procedures in all aspects of the mineral deposit evaluation to ensure the best possible confidence in resultant mineral Resource and Reserve estimates are achieved; the quality of an estimate is dependent on the quality of the data used
Reverse Circulation Drilling	Or RC drilling - uses rods with inner and outer tubes, the drill cuttings are returned to surface inside the rods. The drilling mechanism is a pneumatic reciprocating piston known as a hammer driving a tungsten-steel drill bit.
