News Release – Vancouver, British Columbia October 18, 2022: Monumental Minerals Corp. (“Monumental” or the “Company”) ((TSX-V: MNRL; FSE: BE5; OTCQB: MNMRF) is pleased to announce the addition of 7,025 hectares of land around the current 5,400 hectares at the Salar de Laguna Blanca Lithium-Brine, Cesium-Sediment project located in the prolific lithium triangle, Chile. The Laguna Blanca property now consists of exploration concessions totaling 12,425 hectares, 100% owned by Lithium Chile Inc. through its wholly-owned Chilean subsidiary Minera Kairos Chile Limitada (“Minera Kairos”) (Fig. 1).

Lithium Chile staked an additional 9,600 hectares and a large portion (73%) of this newly staked area falls under an area of influence “AOI” of 5 km as per the Definitive Agreement between Monumental Minerals and Lithium Chile signed on March 31, 2022. Monumental Minerals believes that the most important area of the additional 9,600 hectares staked by Lithium Chile is within the 5 km radius. Monumental Minerals retains the option to earn up to a 75% interest in these additional concessions under the current terms of the Definitive Agreement between Monumental Minerals and Lithium.

The Laguna Blanca Project is within the eastern Andean Geomorphic Belt of Chile’s Central Andean Altiplano and is located 120 km from the Salar de Atacama, the largest producing salar in the world. The felsic volcanic rocks of the Central Andean Altiplano are enriched in Li and Cs. Seasonal rain and snow melt leaches and transports Li, Cs, Ca, Na, Mg, K, and B into the enclosed Laguna Blanca salar. With no outlets, evaporation concentrates these elements within the salar brines.

Dr. Jamil Sader, CEO and Director comments

“We are very excited to have expanded our Laguna Blanca Salar land position, as well as our partnership with Lithium Chile. With the additional exploration concessions, the Project now encompasses a significantly larger part of the salar basin, and will further enhance and extend our lithium brine exploration activities in this highly prospective region.”
