Monumental Energy Corp. Provides Update On Its Laguna Blanca Chilean Lithium Brine-cesium Sediment Salar

VANCOUVER, May 7, 2024 - Monumental Energy Corp. ("Monumental" or the "Company") (TSXV: MNRG) (FSE: BE5) (OTCQB: MNMRF) is pleased to announce the latest Chilean Government update on its Lithium Strategy. On April 15, 2024, Chile, through its Ministry of Mines, launched the process for Chilean and foreign investors to express interest in developing projects to explore and/or extract lithium from deposits located in Chile. Under this strategy, the Ministry of Mines has approved the procedure for the Request for Information ("RFI") which is intended to obtain the information necessary to promote the implementation of projects for the exploration, extraction and processing of lithium deposits and to design the mechanisms, requirements and conditions for granting special lithium operation contracts.

Monumental, through its Chilean subsidiary, Monumental Minerals Chile SpA, announces its plan to file a RFI to pursue necessary exploration for future lithium operation contracts related to 'Project Laguna Blanca'. The Company acknowledges the Chilean Government's prioritization of areas of interest and confirms that the Laguna Blanca Brine System falls within eligible territories for the RFI process.

Michelle DeCecco, CEO remarks, "These announcements affirm Chile's commitment to upholding its role as a leading lithium player for the global energy transition. I commend Chile for facilitating the involvement of companies like Monumental Energy in the national lithium market. Moving forward, we remain dedicated to proactive engagement and collaborative with the Government and the local communities in our Project's area."
