Drilling to Commence at Agdz Copper-Silver Project, Morocco

 

Aterian Plc

("Aterian" or the "Company")

 

Aterian Plc (LSE: ATN), the critical metal-focused exploration and development
company, announces that its maiden Moroccan scout drilling programme is to
commence imminently at the Company's 100% owned Agdz Copper-Silver ("Cu-Ag")
Project ("Agdz" or the "Project"). The Project, covering 34.5 km(2), is
located within the eastern Anti-Atlas Mountains of the Kingdom of Morocco
("Morocco").

Highlights:

·     The 1,000-1,200 m Reverse Circulation ("RC") drilling programme
will commence imminently at the Agdz project site with an initial ten drill
holes anticipated.

·      The RC drill rig has mobilised to the site, with access upgrades
and drill pad preparation underway.

·      Drill holes will target mapped structural and geophysical targets
over four priority prospects:

o  The 2.80 km long Makarn - Makarn North prospect targeting up to 8.00 % Cu
and 448 g/t Ag;

o  The 2.00 km long Amwaro prospect targeting up to 4.82 % Cu, 189 g/t Ag and
1.90 g/t Au;

o  The 0.15 km long Miniére prospect targeting historic workings, spoil up
to 13.05 % Cu and 12 g/t Ag and 0.8 g.t Au;

o  The 0.70 km long Daoud prospect targeting 2.71 % Cu, 152 g/t Ag and 2.96
g/t Au.

·   Geophysical targets were defined from a previously completed
137-line-km IP gradient array and a 12-line high-resolution IP survey.

·   Agdz has demonstrated excellent copper-silver prospects from ground
sampling and is 14 km southwest of the Managem Bouskour copper-silver mine (53
Mt at 0.8 % Cu and 9 g/t Ag).

 

Charles Bray, Chairman of Aterian, commented:

"We are pleased to report that our maiden Moroccan drill programme will
commence imminently at the Agdz Copper-Silver Project in central Morocco.  We
anticipate approximately ten scout holes, with depths of 100 - 120m, utilising
RC drilling.  We are especially excited to advance the status of our projects
in Morocco and to  begin drilling at Agdz.  We are presently in the process
of rationalising and prioritising our projects in the country with the aim to
advance additional projects to the drilling stage. At Agdz, the ground
preparatory works are progressing rapidly, and the main access infrastructure
upgrades are nearing completion. The drill programme has been designed to test
several geophysical and structural targets within four priority target areas
defined to date across the project. The geophysical anomalies scheduled for
testing represent near surface targets, varying from 300 m to greater than 2.5
km in strike length.

 

''Agdz is well situated within an active mining district and is served by
regional infrastructure, lying 2 km from a recently upgraded all-weather road,
35 km from the city of Ouarzazate and 40 km from the Noor-1 solar power plant.
We expect to receive initial assay results by the end of Q3 and look forward
to updating shareholders in due course."

 

Agdz Drill Programme:

The planned drill programme comprises 10 RC drill holes, totalling 1,100 -
1,200 m. Drill samples will be assayed for a multi-element suite of elements,
with selected intervals assayed for gold by fire assay, where earlier surface
rock chip sampling returned anomalous gold values.

 

The drill programme will focus on achieving several objectives:

·      To intersect mineralisation of a suitable grade and width to be
deemed as showing economic potential.

·      To understand the down-dip continuity of the copper-silver
mineralisation mapped and sampled at the surface within outcropping alteration
zones.

·      To provide geological and geochemical datasets to aid in defining
a deposit-scale model.

·      To provide geological and geochemical datasets with which to aid
in the interpretation of geophysical anomalies.

 

 

 

Project Summary:

The Company's wholly-owned subsidiary, Aterian Resources Limited, holds a 100
% interest in the 34.5 km(2) Agdz Copper-Silver Project. The Project lies in
the Souss-Massa-Drâa region of the Anti-Atlas Mountains of central Morocco,
approximately 350 km south of the capital, Rabat, and approximately 35 km east
of the city of Ouarzazate where high-standard infrastructure and services
exist, including a regional airport. The 'Noor 1' solar power station, the
world's largest concentrated solar power plant with a planned output of 580
MW, is located approximately 40 km northwest of Agdz. The Project is accessed
via a paved road, a network of unpaved roads, and vehicle tracks close to and
within the licence.

 

Agdz lies approximately 14 km southwest of the Bouskour copper-silver mine (53
Mt at 0.8 % Cu and 9 g/t Ag), with the world-class Imiter silver mine (131 Moz
of silver at 500 g/t Ag) located 80 km northeast of the Project. Both deposits
are operated by the Moroccan mining company, Managem Group (it should be noted
that mineralisation hosted at the adjacent mines is not necessarily indicative
of mineralisation at Agdz).

 

 

Aterian Exploration Results:

Geological mapping and outcrop sampling, reconnaissance surface trenching, and
ground-based geophysical surveys (magnetics, spectrometry, IP gradient array
and high-resolution IP) undertaken on the Project have defined four priority
prospects at Agdz, namely:

 

·    The Makarn - Markarn North Prospect: A swarm of mineralised dykes,
shears, and veins that predominantly strike NNE over a lateral distance of 2.8
km. Earlier results include 8.00 % Cu and 448 g/t Ag from rock chip samples*.
Four linear, north-to-northeast trending geophysical anomalies of 2.5 km, 600
m, 400 m and 375 m have been interpreted from IP data.

·    The Amzwaro Prospect: Multiple NNE and NNW trending structures within
a zone up to 2 km long and 200 m wide, bound by extensional structures.
Individual alteration zones are up to 33 m wide. Alteration comprises
predominantly chlorite and silica in breccia and veins. Historical results
include rock chip grades of 4.82 % Cu, 189 g/t Ag and 1.91 g/t Au. Two
discrete geophysical anomalies of 575 m and 375 m strike length have been
interpreted from IP data.

·    The Minière Prospect: This 150 m by 90 m zone of historical
underground artisanal mining exploits multiple sub-parallel copper-bearing
zones associated with chloritic-potassic alteration. Historical results
include rock chip and spoil sample grades of 13.05 % Cu, 12.90 g/t Ag, and
0.49 g/t Au.

·    The Daoud Prospect: A series of NNW striking quartz veins and
pervasive silicification, mapped discontinuously over a 700 m strike length
and crosscut by ENE striking chlorite-rich alteration zones. Historical
results include rock chip grades of 2.71 % Cu, 152 g/t Ag, and 2.96 g/t Au.
Mineralisation at the surface coincides with a 900 m-long linear geophysical
anomaly interpreted from IP data.

*A rock chip or grab sample cannot be taken as a representation of the overage
grade average and potential deposit size. A float sample is collected from
loose pieces of rock not connected to an outcrop.
