International Metals Mining Corp. Options Exploration Assets in “Lithium Valley“ Brazil

Lithium Plus is a party to an option agreement (the "Option Agreement") for the acquisition of a 65% right, title and interest in and to certain mining claims in the state of Minas Gerais, Brazil (the "Property"). The Property comprises 12 claims totaling 21,136.73 hectares of surface area.

The Property is strategically located approximately 25 kilometers east from Sigma Lithium Corporation's ("Sigma Lithium") Groto do Cirilo Project and Lithium Iconic Inc.'s ("Lithium Iconic")) Itinga Project, and within proximity to Atlas Lithium Corp., in southeastern Brazil. Sigma's properties are located in the municipalities of Araçuaí and Itinga, in Brazil's mining-friendly Minas Gerais, approximately 450 kilometres northeast of the state capital of Belo Horizonte. Sigma holds 27 mineral rights in four properties spread over 191 square kilometres (19,100 hectares), which include nine past-producing lithium mines.

The Company intends to conduct a satellite imagery-based spectral analysis to determine areas of interest for targeted exploration. Following this, the Company intends to mobilize an exploration team immediately to the prospective areas to conduct initial groundwork, including grab and channel sampling, trenching, and mapping. There will be a focus on identifying pegmatites across the claim blocks that have the potential for lithium-cesium-tantalum (LCT) mineralization.

The Company notes that mineralization hosted on adjacent and/or nearby and/or geologically similar properties is not necessarily indicative of mineralization hosted on the Company's properties.

Pursuant to the terms of the Share Exchange Agreement, as consideration for the sale and transfer of the Lithium Plus shares to the Company, the Company will issue to the Shareholders an aggregate of 12,000,000 common shares of the Company.
