“We are thrilled to be working with such an established and highly regarded Chilean engineering compa ny

during this next important phase of the development of our Penco rare earths deposit in Chile. P&A has a

reputation for designing cost effective , and fit-for-purpose mine and process facilities and bring a wealth of

local project development knowledge due to their long-standing presence in Concepcion, Chile. Aclara is

pleased to continue its support of the local Chilean workforce through awarding the contract to P&A, as the

design work will be undertaken in their offices in Concepcion. We look forward to working collectively with

P&A to advance the Penco Feasibility Study.”

About Aclara

Aclara Resources Inc. (TSX: ARA) is a development-stage rare earth mineral resources company with its

principal project located in Chile. The Company is focused on the development of its mineral resources

through a project called the Penco Module, which covers a surface area of approximately 600 hectares and

hosts ionic clays rich in rare earth elements. Aclara is currently focused on the development and future

construction and operation of the Penco Module, which will aim to produce a rare earth concentrate through

a processing plant that will be fed by clays from nearby deposits. Aclara’s extraction process offers several

environmentally positive attributes such as: no blasting, crushing, or milling; no tailings facility; minimal water

consumption due to a high level of water recirculation; is amenable to leaching with a fertilizer; and contains

no radioactivity. In parallel with the development of the Penco Module, the Company intends to define

additional opportunities to increase potential future rare earth element production via intensive greenfield

exploration programs and the development of additional project “modules” within the Company’s

concessions.
