Altus Strategies Plc
(“Altus” or the “Company”)

Altus Strategies Plc (AIM: ALS), the Africa focused exploration project generator, announces results from its recently completed reconnaissance exploration programme at its 100% owned 412km2 Daro licence (“Daro” or the “Project”) located in the Tigray Regional State of northern Ethiopia.


  • Potential for VMS discovery with a 2kg float sample returning 34.3% Cu and 0.54g/t Au
  • Hard rock gold workings and copper bearing gossans defined at 2.5km long Teklil prospect
  • Significant artisanal alluvial gold mining area covering approximately 900m x 500m
  • Follow up stream sediment sampling programme across 165km2 of Daro now underway

Steven Poulton, Chief Executive of Altus, commented:
“A 2kg sample of gossanous float returning 34.3% copper and 0.54 g/t gold from our initial reconnaissance programme at Daro is highly encouraging. As is the presence of such extensive alluvial, as well as a number of hard rock, artisanal gold mining sites. Furthermore, the discovery of high grade copper mineralised gossans by our field team suggests that the local geology at Daro is prospective for VMS style orebodies. Regionally Daro is located in the ‘Nakfa Terrane’ which hosts a number of significant VMS base metal and gold deposits and mines, including 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.

“The speed of our initial discoveries at Daro is testimony to the efficiency and methodology of our exploration approach. In order to now further define the most prospective gold and copper primary targets, our field team have commenced a 165km2 stream sediment survey. We look forward to updating shareholders on the results from this programme in due course.”

Phase 1 Reconnaissance Programme
The recent reconnaissance exploration programme at Daro has focused on identifying potential gold and copper mineralised Volcanogenic Massive Sulphide (“VMS”) deposits within the licence. To guide the reconnaissance programme the Company first undertook a licence wide remote sensing programme, using satellite-borne imagery to generate a number of prospective targets for initial ground truthing.

The Teklil Gold-Copper Prospect
The reconnaissance programme has led to the discovery of the Teklil gold-copper prospect, a 2.5km long zone of interest that has been prospected and which remains open along strike. Teklil hosts a series of alluvial and hard rock gold workings which can be up to 4m deep, a few meters wide and up to 100m long. In addition in-situ gossans and gossanous float material have been observed discontinuously along the strike length of Teklil. Encouragingly a 2kg sample of gossanous float at Teklil returned a copper grade of 34.3% Cu and also contained 0.54g/t Au, 10g/t Ag and 374ppm Zn. The suite of metals from this sample is considered to be consistent with a potential Kuroko type or bimodal VMS system. Elsewhere at Teklil samples collected from in-situ gossan returned encouraging grades of 7.51% Cu, 3.09% Cu and 2.79% Cu as well as anomalous zinc (857 ppm) and cobalt (496 ppm).

Geological Setting of the Teklil Prospect
Daro hosts an ophiolite complex, being a major thrust-bound belt of mafic and ultramafic geological units which is up to 5.5km wide and extends along a NNE-SSW trend for approximately 21km. The Teklil prospect is considered to comprise a ‘high strain’ inlier of similarly trending metasedimentary rocks, which are up to 250m wide and have an interpreted strike length of approximately 2.5km to date. This zone spatially coincides with a thrust zone previously mapped by the Ethiopian Geological Survey. The highly foliated metasiltstones and quartzites at Teklil are surrounded by a suite of ophiolitic units, including deformed pillow lavas and altered metabasites, with brecciated stockworks also being found in the vicinity.

Further Discoveries
In addition to Cu-Au-Co-Zn mineralisation discovered at the Teklil prospect, a reconnaissance grab sample collected from an artisanal working located approximately 7km to the north and along strike of Teklil returned 81.6g/t Ag and 1.2% Pb with 0.874g/t Au. Approximately 4.5km northwest of the Teklil prospect the Company has identified an extensive area of current and historic intensive artisanal alluvial gold mining within the Ilawit river valley. The workings cover an area of approximately 900m by 500m and typically comprise densely spaced but discrete oval pits (typically 1-3 m wide and dug to a similar depth). Based on the drainage analysis undertaken by the Company it is considered highly likely that the primary source for the gold is located within the Daro licence area. Separately and approximately 4km southwest of Teklil, a number of zones of copper bearing metasiltstone (up to 20m wide) have been identified by the Altus field team. Assay results from this prospect area are currently pending.

Next Phase of Exploration: Stream Sediment Survey
A comprehensive stream sediment sampling programme is now underway, with 137 samples planned to be collected from the primary catchments across 165km2 of the Daro licence. The objective of this programme is to establish which tributaries potentially host primary gold and / or copper mineralisation. The programme is expected to be completed by the end of February.

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 bisects the licence from southwest to northeast, interpreted to be an ophiolite complex of ancient oceanic crust and seafloor sediments. Historical data compilation of Daro, undertaken by the French governmental Bureau de Recherches Géologiques et Minières, 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.
