March 31, 2022

/CNW/ - Monumental Minerals Corp. ("

Monumental

" or the

"

Company

") (TSXV: MNRL) (FSE: BE5) is pleased to announce that the Company has entered into

an arm's length definitive option agreement dated

March 30, 2022

(the "

Option Agreement

") with

Lithium Chile Inc. ("

Lithium

Chile

") (TSX-V: LITH) to acquire up to 75% of the 5200-hectare

Salar

De Laguna Blanca

project (the "

Laguna Project

") located near the town of

San Pedro

de Atacama,

Chile

(see news release dated

March 9, 2022

).

The Laguna Project is located within the prolific lithium triangle, a zone within the central Andes high

desert that includes

Chile

,

Argentina

, and

Bolivia

. This zone is estimated to contain more than half of

the world's lithium supply beneath the many salt flats, also known as salars, that are common to the

region. The Laguna Blanca property consists of 23 exploration concessions totaling 5,200 hectares,

100% owned by Lithium Chile through its wholly owned Chilean subsidiary Minera Kairos Chile

Limitada. The Laguna Project includes both active and paleo salar brines and salts.

Jamil Sader

, Monumental's CEO comments:

"

The Laguna Blanca lithium asset has the potential to become a significant cesium-lithium deposit

in the region. The Project is complimentary to the Company's flagship Jemi heavy rare earth

element project in

Coahuila, Mexico

, and the strength of these two assets will position Monumental

to take advantage of the global shift of decarbonization, and to add significant value for

shareholders. Certain members of the Company's team are currently in

Chile

conducting a site

visit and will be on the Jemi project in

Mexico

shortly thereafter."

About Critical Metals

The US government has identified lithium and select rare earth elements (REEs) as critical metals,

and there is currently a strong push to curtail the US reliance of these metals from sources that are

not politically friendly. On

February 22, 2022

, US government announced government financial

incentives for both lithium and REE producers to develop downstream processing and refining of

REEs and lithium. Additionally, a bi-partisan US senate bill recently passed, which would make it

illegal for US defense contractors to procure REEs from

China

. Monumental Minerals is positioned

to play a significant role in lithium and REE stability and sustainably in the Americas.

TERMS OF THE OPTION AGREEMENT

In order to exercise the option to acquire a 75% interest in the Laguna Project, Monumental must

issue common shares, make certain staged cash payments to Lithium Chile and incur exploration

expenditures on the Laguna Project as follows:
