Temas Resources Signs North American and European Licensing Agreement with MetaLeach™
Temas Resources Signs North American and European
Licensing Agreement with MetaLeach™
• Technologies are environmentally friendly and lower cost compared to
existing leaching processes.
• Targeting copper, nickel, cobalt and zinc producing operators.
• Potential for major operating and capital cost savings (expected to be a
minimum 30-40% vs current technologies).
• Offering a reduction in carbon footprint when compared to conventional
processing methods.
• These processes are complementary to the suite of processes being acquired
from ORF and should allow Temas to be able to provide a lower carbon
footprint for mineral processing than currently commercially available.
VANCOUVER, British Columbia, [ March 29, 2021] ― Temas Resources Corp. (CSE:
TMAS, OTCQB: TMASF) ( the “Company” or “Temas Resources”, is pleased to an-
nounce that it has signed an exclusive North American and European Licensing Agree-
ment with MetaLeach Limited (www.metaleach.com) for its innovative leaching pro-
cesses AmmLeach®, HyperLeach®, NickeLeach®, and MoReLeach® and others.
By licensing MetaLeach™ technology, Temas’ objective is to provide the lowest cost
processing of base metals. This is integral to the delivery of technologies and products
for now and in the future, especially ‘energy and battery’ metals. This objective will
be achieved from the commercialisation of the proprietary & patented hydrometal-
lurgical metals processing technologies (“Leaching Technologies”).
“This opportunity brings tremendous potential for attracting strategic partners who
want a lower cost, environmentally friendly mineral processing solution for their pro-
ducing mines,” said Michael Dehn, CEO of Temas Resources. “We will be open to
engaging partnerships on an equity basis and/or licencing agreements with royalty
arrangement. Direct ownership of mineral projects will also be considered.”

The Leaching Technologies have the potential to revolutioni ze the extraction
processes for many base metal deposits. Reducing capital and operating costs and/or
improving recoveries, and hence enhancing operating margins at the mine site.
Being capable of producing metal or high value product on-site greatly enhances the
mine gate economics compared to conventional concentrators. In addition, in many
cases, the technologie s will enable the treatment of base metals deposits which
hitherto have not been possible to treat. The technologies are especially suitable for
high-acid-consuming carbonate (oxide) hosted ores.
The merits of the Leaching Technologies and commercial adoption success are based
on the potential for major operating and capital cost savings ( expected to be a
minimum 30-40% vs current technologies). This would be suitable and amenable for
mines using the Leaching Technologies as the principal mineral processing method,
to produce base metals or high value product, at the mine site.
In addition, the se Leaching Technologies offer other significant operating and
environmental benefits, including a reduction in carbon footprint when compared to
conventional processing methods. The base metals of most commercial importance
are essential for supplying the raw materials for the electric vehicle revolution, energy
generation and storage technol ogies allied with ESG (Environmental and Social
Governance) policies that these Leaching Technologies target are copper, nickel,
cobalt and zinc.

The path to greener nickel production with NickeLeach®
The NickeLeach® process offer a cost effective, environmentally friendly
method of processing lateritic ores and concentrates to produce separate nickel
and cobalt products. The process operates at ambient temp erature and
pressure, greatly reducing the cost and complexity of a process plant when
compared with all other available technologies.
The acid processes consume vast quantities of sulphuric acid whilst
NickeLeach® recycles the leaching agent greatly reducing costs. The
omnivorous nature of the acid processes results in the production of very
substantial volumes of precipitated wastes (hæmatite, gœthite, jarosite,
gypsum etc.) which need to be stored in a lined tailings facility to eliminate
any acid drainage problems. The highly selective nature of the NickeLeach®
process eliminates any precipitation steps, the tailings revegetate rapidly and
can be stored safely with minimal monitoring.
The ambient conditions used in the NickeLeach® process greatly reduce the
capital cost of the plant compared to the high- cost materials required in the
acid processes. The recycling of the main leach reagent also greatly reduces
the cost compared to acid processes.
