Arc Minerals reports elevated copper intersections at the Kalaba prospect

Arc Minerals is pleased to report additional Reverse Circulation (“KRC”) and Diamond Drill (“KDD”) assay results from the Company’s 11,000m drilling programme at the Kalaba prospect, part of its Zamsort Copper-Cobalt Project (“Zamsort”).

Nick von Schirnding, Executive Chairman of Arc Minerals commented:”The results of our drilling programme continue to be very encouraging with these further drill results showing elevated Copper intersections. The drilling to date demonstrates that at Kalaba the source and migration of the mineralising fluids has been quite extensive and we are now beginning to intersect some of the higher grade ‘traps’.

Given the activity on the ground as well as the large number of samples that are currently being sent to the lab, we anticipate a strong pipeline of news flow and we look forward to updating shareholders on these developments.”

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.

5)    * KRC019 was prematurely terminated in mineralization due to difficult drilling conditions

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 Zamsort. 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 remaining drill holes are 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 programme 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.

Qualified Persons

The information in this press release is based on information provided by Zamsort Limited on behalf of Arc Minerals.  Mr Vassilios Carellas (BSc (Hons), MAusIMM) is the Chief Operating Officer for Arc Minerals and has sufficient experience relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined under the JORC Code (2012).  Mr Carellas consents to the inclusion in this announcement of the matters based on his information in the form and context in which it appears.
