About Aclara

Aclara Resources Inc. (TSX: ARA) is a development -stage company that is focused on heavy rare earth

mineral resources hosted in Ion -Adsorption Clay deposits. The Company ’s rare earth mineral resource

development projects include the Penco Module in the Bio-Bio Region of Chile and the Carina Module in the

State of Goiás, Brazil.

Aclara's rare earth extraction process offers several environmentally attractive features. Circular mineral

harvesting does not involve blasting, crushing, or milling, and therefore does not generate tailings and

eliminates the need for a tailing’s storage facility. The extraction process developed by Aclara minimizes

water consumption through high levels of water recirculation made possible by the inclusion of a water

treatment facility within its patented process design. The ionic clay feedstock is amenable to leaching with

a common fertilizer main reagent, ammonium sulfate. Further, harmful levels of radionuclides, typical of

hard rock rare earth deposits, are not concentrated within the Aclara’s processing flowsheet. In addition to

the development of the Penco Module and the Carina Module , the Company will continue to identify and

evaluate opportunities to increase future production of heavy rare earths through greenfield exploration

programs and the development of additional projects within the Company's concessions in Brazil, Chile,

and Peru.
