DIDCOT, UK / ACCESSWIRE / May 9, 2019 / Altus Strategies Plc (AIM: ALS & TSX-V: ALTS), the Africa focused project and royalty generator, provides an update on it its 100% owned Agdz copper project ("Agdz" or the "Project") located in the Eastern Anti-Atlas of the Kingdom of Morocco.
- Recent rock chip sampling results include 2.22 % Cu, 52 g/t Ag and 2.96 g/t Au
- 50 line kilometre Induced Polarisation geophysical survey ("IP survey") now planned
- IP survey to cover four key prospects:
- 2.0km Amzwaro prospect with grades including 4.82 % Cu, 189 g/t Ag and 1.91 g/t Au
- 2.8km Makarn prospect with grades including 8.00 % Cu, 448 g/t Ag and 0.73 g/t Au

- Discovery of further copper mineralisation within rhyolite dome target
Steven Poulton, Chief Executive of Altus, commented:
"We are pleased to report on further encouraging copper and silver results from exploration at our Agdz project in the Eastern Anti-Atlas of Morocco. Our mapping and sampling programmes are confirming the presence of multiple mineralised and altered structures which are potentially analogous to those reported at the adjacent Bou Skour copper-silver mine located 14km northeast of Agdz which is operated by Managem.
"The next phase of work at Agdz is planned to include a 50 line kilometre IP survey, across the priority prospects we have defined to date and including the recently mapped rhyolite dome target. This survey will be designed to delineate priority trench and drill targets. We look forward to updating shareholders on our progress at Agdz in due course."

IP Geophysical Survey
The planned IP survey will cover 50 line kilometres across the northern portion of the Agdz licence. The programme is designed to delineate potential sulphide copper and silver mineralisation. The targets are interpreted to be located within meters of the weathered surface and in intensely altered, brecciated and fractured zones. Mapping, trenching and ground magnetic surveys completed by the Company indicate that these zones form repeating sub-parallel packages which are individually up to 33m in width and strike in a broadly northeast orientation. Data generated by the IP survey will be applied to guide follow up trenching and drilling programmes.
Summary: Multiple NNE and NNW trending structures within a zone up to 2km in length and 200m wide, bound by extensional structures
Historical results: Rock chip grades include 4.82 % Cu, 189 g/t Ag and 1.91 g/t Au
Planned IP line kilometres: 11.5km

Historical results: Rock chip grades include 8.00 % Cu and 448 g/t Ag

Summary: A 150m long and 90m wide area of historical underground artisanal mining, exploiting multiple sub-parallel copper bearing zones of alteration.
Historical results: Rock chip and spoil sample grades include 13.05 % Cu, 12.90 g/t Ag and 0.49 g/t Au
Planned IP line kilometres: 3.5km
Summary: A series of NNW striking quartz veins and pervasive silicification, mapped discontinuously over a 700m strike length transected by ENE striking chlorite rich alteration zones
Historical results: Rock chip grades include 2.71 % Cu, 152 g/t Ag and 2.96 g/t Au
Planned IP line kilometres: 4.5km
Rhyolite Dome Target (Makarn Prospect)
Recent mapping and sampling by Altus has confirmed the presence of an approximate 1km long and 0.5km wide northeast trending elongate rhyolite dome, located between the Amzwaro and Makarn Prospects. The dome is developed along a mapped northeast striking high angle fault and is likely related to the development of the Oued dar'a caldera which is located 4km to the northwest. The rhyolite dome target will be included in the planned IP survey. Previous trenching within highly weathered outcrop of the rhyolite dome intersected disseminated and vein-hosted copper oxide and copper sulphides (including chalcopyrite and bornite) associated with k-feldspar, iron, chlorite and minor silica alteration over 14.8m. Channel sampling at approximately 1m intervals returned a previously reported grade of 0.2% Cu over 14m.

The Company's wholly owned subsidiary, Aterian Resources Limited, has a 100 per cent interest in the 59.7km2 Agdz Project. The Project comprises four contiguous licence blocks in the Souss-Massa-Drâa region of the Anti-Atlas mountains of central Morocco, approximately 350km south of the capital Rabat. The Project is approximately 14km southwest of the Bou Skour copper-silver mine and 80km southwest of the world-renowned Imiter silver mine, both operated by the Moroccan mining group Managem. Bou Skour has a reported (non-JORC and not reported in accordance with NI43-101) resource of 20Mt at 1.6% Cu and 20 g/t Ag. Agdz is located approximately 35km east of the city of Ouarzazate, where infrastructure and services are of a high standard, including a regional airport. The Project is located approximately 40km south east of the 'Noor 1' solar station, the world's largest concentrated solar power plant which has a planned output of 580 MW. Agdz is accessed via a paved road and a network of unpaved roads and vehicle tracks close to and within the licence.
Agdz Project: Geological setting
Agdz is located proximal to the Oued Dar'a Caldera, which formed within a brittle pull apart structure along a northeast trending regional fault zone in the eastern Anti-Atlas. The caldera is located within the highly prospective Neoproterozoic Sidi Flah-Bou Skour inlier of the Saghro Massif, which developed during Pan-African tectonic events. This massif is comprised of a lower tightly folded volcano-sedimentary sequence formed from arc-related metagreywacke and metavolcanics lithologies deposited approximately 650Ma. The lower complex was intruded by diorite, granodiorite and lesser gabbro and monzogranite between 615Ma and 575Ma. The upper complex is comprised predominantly of felsic metavolcaniclastics related to the development of several calderas emplaced typically between 575Ma and 540Ma and is intruded by granitic plutons. The upper complex is gently folded, sitting unconformably on the lower complex. Regionally, ore deposits are commonly associated with the upper complex and are typically spatially related to magmatic emplacement.
The geology at Agdz comprises meta-sedimentary and meta-volcanic sequences. These belong to the upper complex and are cut by a series of sub-parallel NE to NW striking brittle faults and alteration zones, a number of which have been historically mined for copper. The alteration (comprising variably of chlorite, iron, silica, k-feldspar, actinolite, carbonate and barite) is generally located within brittle pull apart fault breccias and fracture zones, between (and oblique to) the mapped lineaments.
Mapping, sampling and ground magnetic surveys undertaken by the Company to date have defined four priority prospects at Agdz namely, Makarn, Amzwaro, Minière and Daoud. The Company has completed a series of 13 reconnaissance trenches at Agdz, totalling 576m in length and excavated to a depth of up to 1m. The trenches have revealed a number of NNE trending alteration zones in packages which are up to 33m wide, beneath a thin cover of soil and float material. Previously reported assay results from 5 of the 13 trenches have been received and reported to date and include 0.65 % Cu and 36.54 g/t Ag over 14.12m and 0.36 % Cu & 13.26 g/t Ag over 13.70m.
Sampling Methodology and Analysis
A total of 62 grab samples were collected as rock chips from outcrop or float from the programmes described in this release. Of the 62 samples:
- Copper: 10 of 62 samples assayed above 0.5 % Cu, ranging from less than 0.0003 % to 2.6 % Cu
- Silver: 11 of 62 samples assayed above 5 g/t Ag, ranging from less than 0.01 g/t to 52.7 g/t Ag
- Gold: 2 of 62 samples assayed above 0.5 g/t Au, ranging < 0.01 g/t to 2.96 g/t Au
All sample preparation and assay was undertaken by ALS Global at their laboratories in Seville (Spain) and Loughrea (Ireland) respectively. Given the early stage nature of these programmes, no Quality Assurance and Quality Control ("QA-QC") samples have been sent for assay.
Rock samples were crushed with 70% passing -2mm. The less than 2mm fraction was pulverized with 85% of the sample passing <75 microns. The fine fraction of each sample underwent a four-acid digestion with ICP-AES analysis for a suite of 48 elements. All samples were analysed for their Au content by 50g Fire Assay method. Samples with more than 1 g/t Au were resubmitted for Fire Assay with a gravimetric finish.
