ACLARA SECURES 100% OWNERSHIP OF THE CARINA MODULE MINING RIGHTS

TORONTO, ON, February 26, 2024 – Aclara Resources Inc. (“Aclara” or “the Company”) (TSX: ARA) is pleased

to announce that the second tranche of the earn-in agreement has been fulfilled, thus securing 100%

ownership of the 8,490 hectares of mining rights comprising the Carina Module. On November 6, 2023, the

Company had previously executed the first tranche of the earn-in agreement securing an initial 51%

ownership interest.

Ramon Barua, CEO, commented:

“We are pleased to report that we have earned 100% interest of the Carina Module mining rights. This significant

milestone is a result of how quickly we have been able to drill the property and obtain favorable results. After

only five months of announcing the discovery of the Carina Module, we have reported a material mineral

resource estimate, a robust Preliminary Economic Assessment, and are in the middle of a piloting program

using Brazilian clays at our pilot plant in Concepción, Chile.

In addition, we continue to advance the project in several fronts, including an ongoing reverse-circulation drilling

campaign to increase mineral resources at depth, the initiation of the environmental and social baseline studies

and the evaluation of several proposals from world -class engineering companies to prepare a pre -feasibility

study. We remain fully committed to deliver a robust project in a fast -track schedule, aiming to produce

sustainable rare earths at a time when the demand is expected to significantly outpace the supply."

Earn-in Agreement

The Company has exercised the option to earn 100% interest of the Carina Module mining rights. In order to

earn the remaining 49%, Aclara fulfilled the following conditions:

• Drilled 2,000 meters within the mining rights that constitute the Project, in addition to the first 2,000

meters drilled to earn the first tranche in 2023;

• Invested US$2.0 million in exploration expenses, in addition to the US$1.0 million previously invested

in exploration expenses to earn the first tranche; and

• Paid the owner of the mining rights a total US$300,000, in addition to the US$200,000 previously

paid to the mining rights owner to earn the first tranche.

The earn-in agreement also considers a royalty payment to the previous owner of the mining rights when the

project is in commercial production. Aclara has an option to acquire 100% of the royalty for US$6.5 million

during the first year of commercial production. The purchase of the royalty is included in the financial model

that underpins the Carina Module Preliminary Economic Assessment released by the Company on January

23, 2024.

About Aclara

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

resources hosted in Ion-Adsorption Clay deposits. Its primary project is known as the Penco Module and is

located in the BioBio Region of southern Chile. The Company is also working on the initial development phase

of a second module, the Carina Module, located in the State of Goiás in central Brazil.

Presently, Aclara has a strong focus on the development, construction, and future operation of the Penco

Module, with the primary objective of establishing a processing plant designed to produce heavy rare earths

concentrate.

Aclara's extraction process offers several environmentally attractive features. It does not involve blasting,

crushing, or milling. Additionally, it does not generate tailings, eliminating the need for a tailings storage

facility. The Company utilizes 100% recycled water and minimizes water consumption through high levels of

water recirculation. The ionic clay feedstock is amenable to leaching with a fertilizer, and harmful

radionuclides are not produced.

Simultaneously, alongside the development of the Penco Module, the Company intends to identify and

evaluate further opportunities, such as the Carina Module, for increasing production of heavy rare earth

elements. This will involve intensive greenfield exploration programs and the development of additional

project "modules" within the Company's mining rights in Brazil, Chile and Peru.
