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.
