Marimaca Secures Water Option for Life of Mine Seawater Supply
November 07 2022 - 7:00AM
Marimaca Copper Corp. (“Marimaca Copper” or the “Company”) (TSX:
MARI) is pleased to announce that it has entered into a water
option agreement to secure the future water supply required for the
Marimaca Copper Project (the “Project”) in Chile. Under the
agreement, seawater would be supplied following its use in cooling
systems at an electricity plant in Mejillones, located 25km from
the Project and operated by one of Chile’s largest energy
suppliers. The option has a term of 5 years, with the ability to
extend for 2 years, and will allow the Company to advance final
Project permitting and technical studies, including water pipeline
studies that are already underway.
The exercise of the option will trigger the
execution of a water supply agreement priced on a take-or-pay basis
for the Project's life of mine, the principal terms of which have
been negotiated and agreed in the option documentation. The agreed
pricing arrangement is at a lower cost than originally projected in
the 2020 Preliminary Economic Assessment (“PEA”) (available on
www.sedar.com). As disclosed in the PEA, and consistent with
Marimaca’s 5 phases of metallurgical test work, the Project is
designed to use seawater-based process solutions in place of fresh
water.
Highlights
- Milestone
de-risking event for the Marimaca Copper Project, secures option
for seawater supply to meet the Project’s expected long-term water
supply requirements
- Water
option provides for an expected increase in water supply volume
requirements relative to the 2020 PEA to account for the scale
increases targeted in the planned 2023 Definitive Feasibility Study
(“DFS”)
- Agreement
provides for the minimum expected requirements for an upscaled
50ktpa capacity copper cathode project, with the ability to flex up
and down to certain thresholds according to site water
requirements
-
Operationally efficient means of water supply with
significant environmental benefits, removing the risk for
potentially adverse impacts of sourcing water from other limited
supplies, such as groundwater
- Freshwater
usage is consistently identified as a key risk to operations in the
Atacama region
- Recycled
water that would otherwise be discharged back into the
ocean
- Option
agreement also secures the power supply for required pumping
infrastructure and provides an option to provide 10% of Project
operational power requirements
- Both are
committed to be provided by certified renewable energy sources,
pursuant to power purchase agreements that will be entered into on
customary market terms in the future
Hayden Locke, President & CEO of
Marimaca Copper, commented:
“Our goal is to build an example of a
sustainable mine, minimizing environmental and social impacts,
while also providing a commodity which is fundamental to the future
of our society. Our water strategy, which removes the use of any
natural sources of fresh water, is a fundamental example of this
goal in action.
“Globally, mining accounts for significant
freshwater use and its use in arid regions, in particular, is an
enormous social challenge. According to Wood Mackenzie, mining
accounts for 3.1% of national water usage in Chile. In the Atacama
Region, this climbs to nearly 50%, which is clearly unsustainable
over the long term.
“Securing this supply represents a significant
milestone in our efforts to continuously de-risk our Project
development strategy. It provides clarity and security on a key
input for our Project’s development but also, in partnering with
existing infrastructure providers, materially reduces the
permitting risk. The use of seawater, as well as the green power
supply commitments provided by our partner, represents a
significant achievement with respect to the Sustainability
Commitments we launched earlier this year and continues the path of
our broader objective of developing a sustainable copper mine in
Chile.
“Congratulations to Laura Rich and her Marimaca
team for this important step in our Company’s development and thank
you to our new partners who have worked so diligently with us to
find a solution which results in benefits for both parties and all
of our combined stakeholders in the exciting Marimaca Copper.”
