Aclara Receives Second Patent FOR Its Innovative Process to Extract Sustainable Heavy Rare Earths
ACLARA RECEIVES SECOND PATENT FOR ITS INNOVATIVE PROCESS TO
EXTRACT SUSTAINABLE HEAVY RARE EARTHS
TORONTO, ON, March 1, 2024 –Aclara Resources Inc. (“Aclara” or the “Company”) (TSX: ARA) is
pleased to announce that the second patent for its groundbreaking process to extract heavy rare
earths in an environmentally friendly way has been received. The patent has been granted in Chile
and is valid for 20 years. It centers around the innovative Circular Mineral Harvesting (C MH)
process created by Aclara, a groundbreaking technique for processing ionic clays housing rare
earths. CMH establishes a fully enclosed flowsheet, setting a new standard for sustainable rare
earth extraction.
Circular Mineral Harvesting – Environmental Attributes:
• No crushing or milling required
• 95% of water used is recirculated
• 99% of the reagent (a common fertilizer) recycled back into the process
• No liquid residues and no tailings dam needed
• No radioactivity

This patent grants Aclara the right to exclude others from using or selling products made by our
unique process. Special emphasis has been placed on two parts of the process; the water and
the reagent recirculation components of the flowsheet , recycled with 95% and 99% efficiency
respectively. Aclara stands apart from other mining operations in our sector by not having a
tailings dam, a distinction achieved through the absence of liquid residues. At the end of the
extraction process, Aclara's environmentally friendly spent clays are suitable for revegetation with
native species, reinforcing the eco-friendly nature of the Company’s extraction process.
Barry Murphy, COO commented:
“This is a great milestone for Aclara, putting the company on track to become the cleanest source
of heavy rare earths in the world. This patent underscores our commitment to innovation in the
Rare Earths industry. Our team’s ongoing dedication to advancing environmental standards goes
hand in hand with our continuous efforts to optimize both CAPEX and OPEX , solidifying our
leadership in responsible resource extraction.”
Our process has been successfully tested at our Pilot Plant in Concepcion, Chile, with ionic clays
from our Chilean project last year, and where the ionic clays from our Brazilian project are being
processed. We are expecting to produce around 10 kilograms of a high -purity heavy rare earths
concentrate for commercial uses, and we should have the results of this piloting campaign in the
next month.
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. The Company currently has two
projects under development: the Penco Module in the Bio -Bio Region of C hile, and the Carina
Project in the State of Goiás, Brazil.
Aclara's rare earth extraction process offers several environmentally attractive features. It does
not involve blasting, crushing, or milling, and therefore does not generate tailings, thus eliminating
the need for a tailings storage facility. The extracti on 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, ammonium sulfate. Further, harmful levels of radionuclides,
typical of hard rock rare earth deposits, are not concentrated within the Aclara flowsheet.
Simultaneously, alongside the development of the Carina and Penco projects, the Company
intends to identify and evaluate further opportunities to increase future production of heavy rare
earths. This will involve greenfield exploration programs and the dev elopment of additional
projects within the Company's concessions in Brazil, Chile, and Peru.
