Arc Minerals Limited - ARCM - Intersects extensive copper cobalt mineralisation

Arc Minerals is pleased to report initial Reverse Circulation Drill ("RC") assay results from the Company's drilling programme at the Kalaba prospect, part of its Zamsort Copper-Cobalt Project ("Zamsort").

Highlights:

·Four RC holes assayed

·Drilling starting to show large scale potential at Kalaba

·Mineralisation open in multiple directions from surface

·Copper and cobalt mineralisation intersected in all holes

·Hole KRC002 intersected 20m at 1.31% CuEq.

·Hole KRC003 intersected 25m at 1.24% CuEq.

·Hole KRC004 intersected 26m at 1.10% CuEq.

·19 diamond drill holes completed with initial assays expected shortly

Nick von Schirnding, Executive Chairman of Arc Minerals commented: "I am very pleased with these excellent initial assay results of the drilling programme. These early results from RC drilling clearly demonstrate the large tonnage and commercial grade potential of the Kalaba prospect.  The results from these first four RC holes present encouraging copper and cobalt mineralisation with intercepts starting from surface.   

Our updated geological model is indicating that the potential resource at Kalaba may be significantly larger than we had anticipated. The mineralisation at Kalaba remains completely open to the north, east and west with thicknesses increasing to the north. 

We look forward to reporting on further progress from the drilling programme as well as report on assay results as soon as they become available. "

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 $2.66/lb copper and $29.26/lb 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

Drill holes KRC001 - KRC004 were drilled along a N-S section approximately 200m east of the current 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 remains open to the north, east and west.

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, 19 diamond holes have been completed totalling over 2,800 meters and 14 RC holes for over 1,000 meters.

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.

To date the drilling has intersected rocks that display a much higher degree of metamorphism than what is typical for the Copperbelt. This has resulted in a far greater thickness of sulphide mineralisation being intersected than previously modelled.

 

Quality Assurance/Quality Control (QA/QC)

The drilling was conducted using RC drilling with samples 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.
