Platinum Group Metals Ltd. Subsidiary Lion Battery Technologies

Granted Second US Patent

New Provisional Patent Filed for PGMs in Lithium Batteries

(Vancouver/Johannesburg) Platinum Group Metals Ltd. (PTM:TSX; PLG:NYSE American)

(“Platinum Group” “PTM” or the “Company”) and subsidiary Lion Battery Technologies Inc.

(“Lion”) reports that the U.S. Patent and Trademark Office has issued a second patent to

Florida International University (“FIU”) related to platinum group metals (“PGMs”) being used

in lithium batteries. Under a sponsored research agreement (“SRA”), Lion has exclusive rights

to all technology being developed by FIU with Lion funding, including granted patents.

The new patent, the second one granted to FIU relating to Lion’s research , was issued on

December 8, 2020 entitled "Battery Cathodes for Improved Stability" with patent number US

10,862,103 B2. The patent covers a preparation method using PGM catalysts in carbon

materials for use as cathodes in lithium batteries , including lithium-ion, lithium -air, and

lithium-sulfur batteries. The new patent broadens protection for US patent 10,734,636 B2

issued to FIU on August 4, 2020 cover ing the composition of carbon cathodes containing

PGMs. Both patents are assigned to FIU and licensed by Lion.

In addition to th e above new patent, a further provisional patent application has also been

filed for specific application of PGMs in most lithium batteries, including current lithium ion

chemistries.

As a result of the advancement in PGM battery research work conducted by FIU and Lion, the

Company and Anglo American Platinum Limited , Lion’s co -founder, have each approved

additional investment in Lion. After this further investment, the Company will own a 53.7%

interest in Lion.

Dr. Bilal El Zahab , the project leader at FIU commented, “ We are pleased to receive the

second, broader method patent for our research work and we are excited about our new

innovations having potential application to most current, state of the art lithium ion battery

chemistry on the market.”

R. Michael Jones CEO of Platinum Group said , “PGMs have many applications in green

technologies, including clean emissions equipment for internal combustion engines, hydrogen

fuel cell applications for power generation in cars and trucks, and now the potential to improve

the performance of battery electric vehicles. It makes sense that PGMs can play an important

role in innovative energy technology as we seek more efficient energy reactions. This is what

the PGMs palladium, platinum and rhodium do – they are powerful catalysts that accelerate

chemical reactions. The potential of PGMs in batteries is obvious; it stares at us from the

periodic table.“

PLATINUM GROUP METALS LTD. …2

Lion is a private company formed jointly in 2019 by Anglo American Platinum and the

Company to accelerate the development of next -generation battery technology using

platinum and palladium. Under the SRA, research and patent applications are being funded

in battery innovations utilizing platinum and palladium to unlock the potential of higher power

to weight ratios in new generation lithium air and lithium sulfur battery chemistries . This

work may now potentially have application to most commercial lithium batteries. Dr. Bilal El-

Zahab, with prior battery research and development experience and p ost-doctoral work

completed at the Massachusetts Institute of Technology, is the head of the Lion battery

research team.

those, which, by their nature, refer to future events. All statements that are not statements of

historical fact are forward-looking statements. Forward-looking statements in this press release

include, but are not limited to, statements regarding research innovations having potential

application to most current, state of the art lithium ion battery chemistry on the ma rket, the

potential of PGMs in batteries to improve the performance of battery electric vehicles, the

development of the Waterberg Project, the market for PGMs, Lion securing future patent rights

and the acceleration of developments of next generation batt ery technology . Although the

PLATINUM GROUP METALS LTD. …3

Company believes any forward-looking statements in this press release are reasonable, it can give

no assurance that the expectations and assumptions in such statements will prove to be correct.

The Company cautions investors t hat any forward-looking statements by the Company are not

guarantees of future results or performance and that actual results may differ materially from

Estimates of mineralization and other technical information referred to or included herein have

been prepared in accordance with NI 43 -101. The definitions of proven and probable reserves

used in NI 43-101 differ from the definitions in SEC Industry Guide 7. Under SEC Industry Guide

7 standards, mineralization may not be classified as a “reserve” unless the mineralization can be

PLATINUM GROUP METALS LTD. …4

economically and legally extracted or produced at the time the “reserve” determination is made.

As a result, the reserves reported by the Company in accordance with NI 43-101 may not qualify

as “reserves” under SEC Industry Guide 7. In addition, the terms “mineral resource”, “measured

mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in and

required to be disclosed by NI 43 -101; however, these terms are not defined terms under SEC

Industry Guide 7 and historically have not been permitted to be used in reports and registration

statements filed with the SEC pursuant to SEC Industry Guide 7. Mine ral resources that are not

mineral reserves do not have demonstrated economic viability. Investors are cautioned not to

assume that any part or all of the mineral deposits in these categories will ever be converted into

reserves. In particular, “inferred mineral resources” have a great amount of uncertainty as to their

existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed

that all or any part of an “inferred mineral resource” will ever be upgraded to a higher categ ory.

Disclosure of “contained ounces” in a resource is permitted disclosure under NI 43-101; however,

SEC Industry Guide 7 normally only permits issuers to report mineralization that does not

constitute “reserves” by SEC Industry Guide 7 standards as in -place tonnage and grade without

reference to unit measures. Accordingly, descriptions of the Company’s mineral deposits in this

press release may not be comparable to similar information made public by U.S. companies

subject to the reporting and disclosure requirements of SEC Industry Guide 7.
