Camino and Nittetsu Commence Proprietary Leaching Studies for Growth Opportunities at the Puquios Copper Project in Chile
Camino and Nittetsu Commence Proprietary Leaching Studies for Growth
Opportunities at the Puquios Copper Project in Chile
VANCOUVER, October 30, 2025 – Camino Minerals Corporation (TSXV: COR) (OTCID: CAMZF)
(“Camino” or the “Company”) is pleased to announce that its joint venture with Nittetsu Mining
Co., Ltd. (“Nittetsu”) will initiate leaching studies at Nittetsu’s metallurgical and chemical facility
in Tokyo. These studies aim to assess the scalability of the Puquios Copper Project (“Puquios” or
the “Project”).
The Puquios mine is planned as a conventional sulphide leaching operation utilizing solvent
extraction and electro winning (“SXEW”) technology. All permits required for commencement
of construction are in place, with mine construction anticipated in the first half of 2026. To
support development, Camino and Nittetsu are actively pursuing a debt facility with a Japanese
lender that is expected to offer highly competitive terms in the current mining finance
environment.
The first stage of the Puquios copper mine development is now on a path towards production.
The Company is evaluating scale-up opportunities targeting the hypogene copper mineralization
located beneath the supergene , soluble copper zones . The Project has approximately 8,170
metres of drilling completed in the primary mineralized zone. Two exploration adits have been
developed to reach the copper mineralization at depth and samples of the deeper mineralization
have been extracted and delivered to Nittetsu’s research and development facility in Tokyo for
testing. Nittetsu has been advancing proprietary copper extraction tech nologies and initial
results demonstrate competitive recoveries for different types of copper mineralization. The
deeper copper mineralization at Puquios will be leached at the facility, for further consideration
for the next phase of the Project’s scale-up.
Looking ahead, the Company intends to further assess and integrate new leaching technologies
to determine the most effective scale-up strategy for expanding copper production at Puquios.

“Camino has been working with Nittetsu for several years and is benefiting from their know-how
in exploration geology and operations. Now we are extending our cooperation to their research
and development business unit in Tokyo”, commented Jay Chmelauskas, CEO of Camino. ”After
we build the first con ventional copper production phase at Puquio s, we would like to grow
production in Chile, and we are starting that work now.”
Shinichiro Mita, General Manager of Nittetsu Mining Co., Ltd. said, “I have recently visited the
Puquios copper project with our technical and management team s in preparation to begin
construction of the mine. We all believe that the project can grow from the first phase of
development, and we are pleased to advance our research to develop economic copper leaching
technologies for Puquios.”
About Camino
Camino is a discovery and development stage copper exploration company. On October 7, 2024,
Camino signed a Definitive Agreement to purchase the construction-ready Puquios copper mine
in Chile. Camino is focused on developing copper producing assets such as Puquios, and
advancing its IOCG Los Chapitos copper project located in Peru through to resource delineation
and development, and to add new discoveries. Camino has also permitted the Maria Cecilia
copper porphyry project for exploration discovery drilli ng to add to its NI43 -101 resources. In
addition, Camino has increased its land position at its copper and silver Plata Dorada project.
Camino seeks to acquire a portfolio of advanced copper assets that have the potential to deliver
copper into an electrifying copper intensive global economy. For more information, please refer
