Stillwater Critical Minerals Appoints Dr. Wolfgang Maier as Senior Geological Advisor

April 20, 2023 - Vancouver, B.C., Stillwater

Critical Minerals Corp. (TSX.V: PGE | OTCQB:

PGEZF) (the “Company”, “Stillwater” or

“SWCM”) is pleased to announce that Wolfgang

Maier, Ph.D. , a recognized world expert

geologist in magmatic mineral deposits , has

joined the Company as Senior Geological

Advisor.

Dr. Maier has more than 25 years of global

experience in mafic -ultramafic igneous systems

and the formation of magmatic ore deposits,

including deposits of nickel, copper, cobalt,

platinum group elements ( “PGE”), and

chromium. He has authored and co-authored

144 publication s which have received 5,175

citations to date and has been a contributing

author or editor of several books, monographs,

and geological maps . Dr. Maier studied geology

at the Ludwig Maximilian University of Munich,

Germany and at Rhodes University, South Africa,

including doctoral studies on the Bushveld

Complex in 1992. He taught igneous petrology

and economic geology at the Universities of

Pretoria (South Africa), University of Quebec at Chicoutimi (Canada), UWA (Australia), and Oulu (F inland) before

joining Cardiff University in 2013 where h e is currently a professor with the School of Earth and Environmental

Sciences. In addition to his work studying the formation of magmatic ore deposits including PGE, Ni-Cu, Cr, and V-Ti-

Fe deposits, Dr. Maier is also interested in increasing the sustainability of both exploration and mining.

Dr. Wolfgang Maier commented, “I am very impressed with the potential of the Stillwater project and excited to

contribute to the exceptional team assembled by Stillwater Critical Minerals. During my site visit in 2022 , I was

impressed by the relatively underexplored nature of the lower Stillwater complex, which is surprising as the Stillwater

Igneous Complex hosts the highest-grade platinum group element reef system in the world and the lower Stillwater

complex shows similar exceptional PGE tenor within the more broadly mineralized nickel, copper, cobalt and

chromium enriched lower magmatic stratigraphy. I look forward to further collaboration as SWCM focuses on

expansion of their current resources and follows up on its exciting high-grade discovery holes in 2023. The potential

for continued discovery of these important battery metals along with significant PGEs at Stillwater is outstanding.”

Dr. Danie Grobler, Stillwater Critical Minerals’ Vice-President of Exploration, stated, “We are very pleased to welcome

Dr. Maier to the technical team at Stillwater in follow -up to his extended tour of the project last year. During his

career, Dr Maier has worked on and published papers about most of the economically important layered mafic -

ultramafic intrusives globally. Dr Maier’s extensive scientific understanding of these important critical metal deposits

complements our experienced exploration team as we prioritize high-grade nickel, copper, cobalt, and platinum group

element mineralized zones within the lower part of the Stillwater layered magmatic stratigraphy. We are currently

finalizing our exploration plans for 2023 which will focus on continued expansion drilling at the resource areas .

Particular focus is planned for targets adjacent to high-grade discovery intersects such as CM2021-05 at Chrome

Mountain which intersected 13.2 meters of high-grade nickel sulphide grading 2.31% Ni, 0.35% Cu, 0.115% Co and

1.51 g/t PGEs+Au within 400.8 meters of continuous mineralization, and CZ2021-01 at I ron Mountain , which

intersected 4.6 meters grading 0.96% Ni, 0.49% Cu , 0.073% Co and 0.87 g/t PGEs+Au within 367.6 meters of

continuous mineralization.”

About Stillwater Critical Minerals Corp.

Stillwater Critical Minerals (TSX.V: PGE | OTCQB: PGEZF) is a mineral exploration company focused on its flagship

Stillwater West Ni-PGE-Cu-Co + Au project in the iconic and famously productive Stillwater mining district in Montana,

USA. With the recent addition of two renowned Bushveld and Platreef geologists to the team, the Company is well

positioned to advance the next phase of large-scale critical mineral supply from this world-class American district,

building on past production of nickel, copper, and chromium, and the on-going production of platinum group and

other metals by neighboring Sibanye-Stillwater. An expanded NI 43-101 mineral resource estimate, released January

2023, delineates a compelling suite of critical minerals contained within five Platreef-style nickel and copper sulphide

deposits at Stillwater West, which host a total of 1.6 billion pounds of nickel, copper and cobalt, and 3.8 million ounces

of palladium, platinum, rhodium, and gold, and remains open for expansion along trend and at depth.

Stillwater Critical Minerals also holds the high-grade Black Lake-Drayton Gold project adjacent to Treasury Metals’

development-stage Goliath Gold Complex in northwest Ontario, currently under an earn-in agreement with Heritage

Mining, and the Kluane PGE-Ni-Cu-Co critical minerals project on trend with Nickel Creek Platinum‘s Wellgreen

deposit in Canada‘s Yukon Territory.

Quality Control and Quality Assurance

2021 drill core samples were analyzed by ACT Labs in Vancouver, B.C. Sample preparation: crush (< 7 kg) up to 80% passing

2 mm, riffle split (250 g) and pulverize (mild steel) to 95% passing 105 µm included cleaner sand. Gold, platinum, and

palladium were analyzed by fire assay (1C-OES) with ICP finish. Selected major and trace elements were analyzed by

peroxide fusion with 8-Peroxide ICP-OES finish to insure complete dissolution of resistate minerals. Following industry

QA/QC standards, blanks, duplicate samples, and certified standards were also assayed.

Mr. Mike Ostenson, P.Geo., is the qualified person for the purposes of National Instrument 43-101, and he has reviewed
