DEEP-SOUTH APPOINTS THE CSIRO OF AUSTRALIA TO CONDUCT THE
BIO ASSISTED HEAP LEACHING TEST WORK
Vancouver, B.C., Canada – May 19, 2021 – Deep-South Resources Inc. ("Deep-South"
or “the Company") (TSX-V: DSM) today announced that it has appointed the world-
renowned Commonwealth Scientific and Industrial Research Organisation (“CSIRO”) to
conduct bio-assisted heap leaching column test work, which is part of Deep-South’s
recently announced metallurgical test work. METS Engineering Group (“METS”) of
Australia has been appointed to supervise and overview the test work.
Pierre Leveille, President & CEO of Deep-South stated, "With the drilling program
under way, we are delighted to initiate a collaboration with CSIRO, Australia’s
national science agency, which is a leader in scientific research and bio-assisted
heap leaching technologies. The main aim of this test work is to improve copper
recoveries and therefore improving the Haib Copper project robust economics.”
The goals of the bio-assisted heap leaching test work include the evaluation of the
performance of promising solvent extraction reagents for extraction and separation of
copper and molybdenum and monitor and evaluate the adaptation of bacterial strains for
improved ore processing. The test work will also monitor and evaluate percolation
performance. The test work will mainly serve to optimise the bio-assisted heap leaching
processes with the ore at Haib.
This initial column test work will assess two size fractions of the ore. One will be at a size
of <2.36 mm and the other one at a size of <1.7 mm. The undersize will be screened at -
106 microns, removing the requirement for agglomeration prior to leaching . The
undersize material (-106 microns) will be the object of a sighter program to assess
amenability to a flotation, roasting and leaching flowsheet. This will further define if overall
target recoveries can be achieved from the fine material and metal extraction can take
place at an increased pace versus column leaching.
About CSIRO
The Commonwealth Scientific and Industrial Research Organisation ( CSIRO) was
founded in 1916 and is Australia's national science agency and one of the largest and most
diverse scientific research organisations in the world. Its research covers subjects such as
natural environments, environmental impacts, health and medical, production and many
others. Dr Anna Kaksonen leads the Industrial Biotechnology Group in the Industry
Environments Program in CSIRO Land and Water. With her Group she develops
biotechnological processes for environmental and industrial applications in the mining,
energy, water supply, waste and wastewater treatment industries. Research topics of special
interest have included: mining biotechnology (e.g. bioleaching, biooxidation, bioprecipitation,
bioflotation). You can visit the CSIRO website here: https://www.csiro.au

About Deep-South Resources Inc
Deep-South Resources is a mineral exploration and development company. Deep-South
holds 100% of the Haib Copper deposit in the south of Namibia. Haib is one of the largest
undeveloped copper deposits in Africa.
The recent preliminary economic assessment showed that at a price of copper of $3.00 /
lb, the project generates an after-tax NPV of $950 million and an after-tax IRR of 30%.
At $4.00 / lb, it generates an after-tax NPV of $1,650 million and an after-tax IRR of 42%.

Deep-South growth strategy is to focus on the exploration and development of quality
assets in significant mineralized trends and close to infrastructures in stable countries. In
using and assessing environmental friendly technologies in the development of its copper
project, Deep-South embraces the green revolution.
