Scout Diamond Drilling Commences at Viuda Negra Prospect, Viuda

 

Targeting epithermal-porphyry style Au-Ag-Cu mineralisation

 

 

Great Southern Copper plc (LSE: GSCU), the company focused on copper-gold
exploration in Chile, is pleased to announce that drilling has commenced on
its Viuda Negra prospect located within the Especularita project.

 

Highlights:

·    Scout diamond drilling commences at Viuda Negra prospect targeting
Au-Ag-Cu mineralisation

·    Initial programme comprises 2 - 4 scout holes for a total of up to
500m

·    Drilling targeting outcropping porphyry-epithermal style alteration
with rock chip samples assaying up to 4.2g/t Au, 45g/t Ag and 0.56% Cu(1)

·    GSC holds options to own 100% of the Viuda and Viuda Negra prospect

·    Project located in coastal metallogenic belt with excellent access
and infrastructure

 

Sam Garrett, CEO for Great Southern Copper in Chile, said: "We are excited to
commence scout drilling at the Viuda Negra prospect where recent exploration
by GSC has identified outcropping evidence of epithermal-porphyry type
mineralisation with assay grades in rock chips and channel chip samples
ranging up to 4.2g/t Au, 145g/t Ag and 0.56% Cu.

 

"The style of gold-rich sheeted veining outcropping at Viuda Negra and
elsewhere across the Viuda prospect, is characteristic of Maricunga type
porphyry gold deposits in Chile. Significantly, this style of gold deposit has
not previously been recognised in the coastal belt of Chile.

 

"The Viuda and Viuda Negra targets emphasise the exciting depth of the
Especularita drilling pipe-line which is further enhanced by the current
environment of record gold and silver prices. The location and scale of the
Especularita project coupled with the deposit style and commodity optionality
on offer remains a key differentiating factor for GSC."

 

Viuda Negra Prospect:

Follow-up mapping of anomalous soil geochemistry results at Viuda has
discovered outcropping sheeted and stockworked, banded quartz-magnetite veins
at Viuda Negra, located 1km to the northeast of Changay Hill (Figure 1), that
are characteristic of Au-rich porphyry systems in Chile. Subsequent channel
chip sampling across the outcrops has returned assays up to 1m at 4.2 g/t Au
and 0.12% Cu(1). Nearby several epithermal-style ledges were also discovered
with intense multi-stage quartz veinlet stockworks associated with epithermal
type advanced argillic alteration. Rock chip sampling of several of the ledges
returned values up to 145 g/t Ag and 0.56% Cu(1) (Figure 2).

Drilling:

Scout diamond drilling has commenced at Viuda Negra to test the outcropping
ridges of anomalous gold and silver mineralisation identified by surface
mapping and sampling. Up to 4 drill holes are proposed for a total of up to
400 - 500m.

 

Hole VNE25-DD001 is currently at 70m depth and testing sheeted, Maricunga
style quartz-magnetite vein alteration at Cruachan Ridge where channel
sampling has returned assay grades up to 4.2g/t Au and 0.12% Cu (Figure 2).
The hole has intersected zones of quartz fracture-veining and hydrothermal
brecciation (Figure 3). Hole VNE25-DD002 is planned to test epithermal style
alteration outcropping at Scarlett Ridge with anomalous silver grades up to
29.9g/t Ag (Figure 2).

Notes for Editors:

 

About Great Southern Copper

 

Great Southern Copper PLC is a UK-listed mineral exploration company focused
on the discovery of copper-gold deposits in Chile. The Company has the option
to acquire rights to 100% of two projects in the under-explored coastal belt
of Chile that are prospective for large scale copper-gold deposits. Chile is a
globally significant mining jurisdiction being the world's largest producer
and exporter of copper.

 

The two, early-stage Cu-Au projects comprise Especularita and San Lorenzo
Projects, both located in the coastal metallogenic belt of Chile which hosts
significant copper mines and deposits, including Teck's Carmen de Andacollo
copper mine, and boasts excellent access to infrastructure such as roads,
power and ports. Significant historical small-scale and artisanal workings for
both copper and gold are readily evident in both exploration project areas.
The coastal belt offers deposit type optionality for copper including porphyry
and IOCG style deposits as well as newly recognised intrusive-related copper
and gold deposits.

 

Great Southern Copper is strategically positioned to support the global market
for copper - a critical battery metal in the clean energy transition around
the world. The Company is actively engaged in exploration and evaluation work
programmes targeting both large tonnage, low to medium grade Cu-Au as well as
high-grade Cu-Ag-Au deposits.
