Altus Strategies provides exploration update on Agdz copper-silver project, Morocco
Tuesday, Sep 12, 2017
Altus Strategies Plc (AIM: ALS), the Africa focused exploration project generator, provides an update on exploration activities at its Agdz copper-silver project (“Agdz”) in central Morocco.

Highlights:

• Reconnaissance trenching has defined numerous mineralised epithermal structures
• Multiple alteration and breccia zones within volcanic and meta-conglomerate sequences
• Previous sampling yielded grades up to 8% Cu, 448 g/t Ag and 3.74 g/t Au
• Systematic trenching programme to be completed in Q4 2017
• Project is located within an established copper-silver mining district

Steven Poulton, Chief Executive of Altus, commented:

“The Agdz Cu-Ag project is a recent discovery by Altus in the heart of a significant and growing copper and silver mining district in central Morocco and 14km south west from the newly opened Bouskour Cu-Ag mine operated by Group Managem. Our field teams have recently completed a 275m reconnaissance trenching programme across two prospects with a combined strike length of approximately 4km and widths up to 0.5km. The trenches targeted bedrock below highly weathered surface material and mapping of these trenches has confirmed the presence of significant alteration zones, as well as copper oxide and sulphide mineralisation.

“Based on the encouraging results from this phase of work the Company will complete a systematic 800m trenching programme across both prospects, to define priority targets for drilling.”

Agdz Project: Reconnaissance trenching results

The Company has recently completed a 275m reconnaissance trenching programme at the Amzwaro and Makarn prospects to an average depth of 0.5m. The trenching was undertaken to confirm bedrock lithology and alteration assemblages in order to assess the correlation between ground magnetic survey data and high grade assay results from surface sampling. Two trenches were dug at the Makarn North prospect (18m and 22m long respectively). Previous surface sample results of weathered rock proximal to MKN-T-02 has returned up to 1.14% Cu and 95.1 g/t Ag. Trench MKN-T-02 revealed silicified and chloritised meta-conglomerates with intermittent zones of copper oxide mineralisation. The surface expression of the meta-conglomerate has subsequently been mapped for over 150m along strike. Trench MKN-T-03 revealed disseminated and vein-hosted copper oxide and copper sulphides (including chalcopyrite and bornite) over 14.8m. Channel sampling at approximately 1m intervals returned a grade of 0.2% Cu over 14m from the highly weathered banded rhyolite host rock.

At the Amzwaro prospect four reconnaissance trenches have been excavated for a total of 236.5m. Three trenches were cut between 10m and 25m long and one (namely AM-T-09) was 192m long. Trench AM-T-09 exposed a series of weathered, highly altered, brecciated and fractured zones in packages over widths of up to 33m. These zones encompassed intense areas of chloritisation, silicification, haematisation and potassic alteration and are interpreted to represent the highly weathered surface expression of a potential primary mineralised source. Notably copper sulphides and oxides were observed in the trench having been near absent at surface. Trench AM-T-10 exposed meta-volcanoclastic with 3.5m of malachite and chrysocolla mapped. Trench AM-T-11 revealed 7.5m of alteration with variable copper oxides mapped over two closely spaced zones. Trench AM-T-12 revealed 3.1m of alteration with copper oxides and galena mapped.

Agdz Project: Next phase of work

The reconnaissance trenching programme has successfully correlated the ground magnetic and surface sampling data with the presence of mineralisation and alteration in weathered bedrock. A phase-one systematic trenching programme, with seven trenches up to 200m each in length is planned, in conjunction with further detailed structural and alteration mapping. The programme will be designed to locate and test the continuity of the primary copper-silver mineralised and / or altered structures to define potential drill targets. The Company may also complete an Induced Polarisation geophysical survey at Agdz prior to finalising these drill targets.
