SALAR

VANCOUVER, BC

,

June 25, 2024

/CNW/ - Monumental Energy Corp. ("

Monumental

" or the

"

Company

") (TSXV: MNRG) (FSE: ZA6) (OTCQB: MNMRF) is pleased to announce the latest

Chilean Government update in the context of its Lithium Strategy. In

April 2024

,

Chile

, through its

Ministry of Mines, announced the process for Chilean and foreign investors to express interest in

developing projects to explore and/or exploit lithium from deposits located in

Chile

. Consequently, the

Ministry of Mines approved the procedure in order to file for a Request for Information ("

RFI

") which

is intended to express interest in developing the exploration, exploitation and processing of Salt Flats

located in

Chile

. This RFI process will allow the Government of

Chile

to evaluate the conditions,

mechanisms and requirements for granting special lithium operation contracts (CEOL).

Monumental, through its Chilean subsidiary, Monumental Minerals Chile SpA, announces that on

June 17, 2024

, it filed a RFI to express interest in the exploration and potential exploitation of its

'Project Laguna Blanca', located in the Laguna Blanca Salt Flat. The Company acknowledges the

Chilean Government's prioritization of available areas of interest and confirms that the Laguna

Blanca Salt Flat has not been categorized as a protected brine system, that consequently, is

considered an eligible territory for this RFI process.
