Altus Strategies Plc (AIM: ALS), the Africa focused exploration project generator, provides an update on exploration activities at its 100% owned 411.7km2 Daro copper-gold project (''Daro'' or the ''Project'') in the Tigray province of northern Ethiopia.


  • Further encouraging grab sample results including 24% Cu and 203 g/t Ag
  • Anomalous cobalt zone discovered within the 2.5km long Teklil Prospect
  • Stream sediment survey covering 270km2 has defined priority drainages
  • Extensive alluvial gold workings along a 9.5km stretch of the Ilawit river
  • Results further support likely Volcanogenic Massive Sulphide (“VMS”) system

Steven Poulton, Chief Executive of Altus, commented:
"We are pleased to report further encouraging results from the recent phase of exploration at the Daro licence situated on the prospective Arabian Nubian Shield of northern Ethiopia. These include rock chip samples grading 24% Cu, 1.19 g/t Au and 203 g/t Ag and highly anomalous cobalt mineralisation (up to 496 ppm Co) along a 1.7km stretch of the 2.5km long Teklil Prospect."

"We also announce the discovery of the Wedihazo prospect which hosts a discontinuous 250m long zone of in-situ copper mineralisation that is up to 15m wide in places. Grab sampling at Wedihazo has returned assays including 1.69% Cu and 1.72% Cu. A float sample collected from a drainage channel 500m downslope of Wedihazo returned 22.3% Cu. Separately results from the Company’s stream sediment sampling have been received. Two priority drainage basins have been defined and extensive artisanal gold workings have been mapped along a 9.5km section of the Ilawit river."

"The next phases of work at Daro will likely include mapping, soil sampling and ground magnetics across the areas prioritised from this programme of work."

Exploration at Teklil Prospect
Follow up exploration has been completed at the 2.5km long Teklil Prospect focussing on previously observed artisanal workings and Cu-bearing gossans, results from which included 7.51% Cu, 3.09% Cu and 2.79% Cu along with 1.01 g/t Au. In addition, a float sample yielded 34% Cu and 0.54 g/t Au. A number of historic gold workings as well as copper-bearing gossans across an approximate 400m by 400m area have been observed at Teklil. The prospect has also returned float samples with high silver assays, up to 203 g/t Ag, as well as anomalous lead up to 0.7% Pb.

Results from the recent programme have established highly anomalous cobalt up to 496ppm Co (~0.05% Co) discontinuously over a zone which is approximately 1.7km in length. The anomalous cobalt values consistently occur in samples with copper assays above 1% Cu, along with anomalous gold and zinc. The mineral association further supports the potential for the Teklil Prospect to host a Cu-Au-Ag(-Co-Zn) VMS system.

Discovery of Wedihazo Prospect
The recent programme has discovered a new prospect at Wedihazo, approximately 4km southwest of Teklil. At Wedihazo, copper bearing metasedimentary rocks have been mapped discontinuously for approximately 250m and which are up to 15m wide in places. Prospecting grab samples have returned assays including 1.72% Cu and 1.9 g/t Au. Approximately 500m downslope from this outcrop, a sample of float has returned 22.3% Cu and 0.24 g/t Au.

Completion of Stream Sediment Survey
The Company has completed a 146 stream sediment sample programme which covered approximately 65% of the 411.7km2 Daro licence area. Results from this programme have established two key drainages covering 20km2 and 48km2 respectively. Detailed mapping of the priority drainage areas will form part of the next phase of work to identify the primary source of the gold mineralisation. This programme may be followed by soil sampling and ground magnetic surveys. As part of the stream sediment programme, numerous alluvial gold workings were mapped along a 9.5km section of the Ilawit river. Some workings occur as abundant closely spaced pits over areas which are up to 200m long x 100m wide.

Sediment Sampling Methodology and analysis
The Company has completed a 146 stream sediment sample programme which covered approximately 65% of the 411.7km2 Daro licence area. Drainage catchments within the licence were defined using 1: 50,000 scale topographic mapping combined with watershed analysis undertaken on a digital elevation model (DEM) which covered the survey area. At each sampling locality, a 4kg sample of <2mm sieved material was collected from trap sites within a 10m radius of each location. At each site, the sample ID, coordinates, elevation, trap site type (if applicable), colour and moisture was noted along with any interesting float material and areas of artisanal workings.

Sample preparation and analysis was undertaken by ALS Global (“ALS”) with the preparation undertaken at the ALS facility in Addis Ababa in Ethiopia. Sediment samples were dried at a temperature of less than 60oC and sieved to -180 micron (80 Mesh). The fine fraction of each sample was sent to ALS’s facility in the Republic of Ireland where samples underwent aqua regia digestion with super trace ICP-MS analysis for a suit of 41 elements. Given the early stage nature of the programme, no QA-QC samples were sent for assay.

Grab sampling (chip and float) Methodology and analysis
Thirteen grab samples were collected as rock chips from outcrop or float. Of the thirteen samples:.

  • Cu: 6 of 13 samples assayed above 1% Cu ranging from trace to 24% Cu
  • Au: 3 of 13 samples assayed above 0.2 g/t Au, ranging from <0.01g/t to 1.19 g/t
  • Ag: 5 of 13 samples assayed above 1 g/t Ag, ranging from <0.5g/t to 203 g/t

Sample preparation was undertaken at the ALS facility in Addis Ababa in Ethiopia. Rock samples were crushed with 70% passing -2mm. The <2mm fraction was pulverized with 85% of the sample passing <75 microns. The fine fraction of each sample was sent to ALS’s facility in the Republic of Ireland where samples underwent a four-acid digestion with ICP-AES analysis for a suit of 61 elements. Given the early stage nature of the programme, no QA-QC samples were sent for assay.

Daro Project: Location
The Daro exploration licence is held by Altau Resources Ltd, the Company’s 100% owned Ethiopia focused subsidiary. The licence is located in northern Ethiopia, 95km west of the Company’s Tigray-Afar Cu-Ag project, 100km northwest of the Tigray state capital of Mekele and 570km north of Ethiopia’s capital, Addis Ababa. Mekele has a regional airport and year-round access to the licence area is provided by a network of maintained surfaced and graded roads.

Daro Project: Geological Setting
The Daro licence is situated within the Neo-Proterozoic Nakfa Terrane, at a junction between two major tectonic blocks and comprises a series of metasedimentary and metavolcanic rocks, affected by thrusting and intrusion of the Rama granite. A band of mafic to ultramafic rocks, interpreted to be an ophiolite complex of ancient oceanic crust and seafloor sediments, bisects the licence from southwest to northeast. Historical data compilation of Daro, undertaken by the French governmental Bureau de Recherches Géologiques et Minières (BRGM), has defined a number of marker lithologies and structures that are considered prospective for VMS deposits. These include the presence of bimodal volcanics and associated sediments, mafic and ultramafic lithologies which conform to an ophiolitic sequence, as well as the presence of extensive chert horizons.

The Nakfa Terrane hosts a number of significant VMS base metal and gold deposits and mines. This includes Bisha, a polymetallic mine operated by Nevsun Resources Ltd (TSX: NSU) 190km north west of Daro, the Harvest and Adyabo projects, being advanced by East Africa Metals Inc. (TSX-V:EAM) 35km west of Daro and the Asmara project being advanced by Sichuan Road & Bridge Mining Investment Corp Ltd 100km north of Daro.
