Aqua Metals Reports Milestone Advancements, Strategic Progress, and Sierra ARC Lithium Battery Recycling Campus Developments in 2024

Validated closed-loop battery recycling technology, built commercial partnerships, and revised economic model to better pursue funding and scale domestic battery mineral production

RENO, Nev., March 31, 2025 – Aqua Metals, Inc. (NASDAQ: AQMS), a pioneer in sustainable lithium battery recycling, today announced key achievements from 2024 and outlined progress for 2025 as the Company delivered critical technical milestones and high-purity material production through its proprietary Li AquaRefining™ process. In the past year, Aqua Metals delivered industry-first milestones, strengthened commercial partnerships and opportunities, and expanded its strategic vision to build a resilient, low-capex, and rapidly scalable platform for critical mineral recovery in the U.S.

The Company’s innovative Li AquaRefining™ process achieved key validation milestones, proving performance at scale while offering superior environmental and economic advantages over conventional recycling methods. With the primary building for Phase One of the Sierra ARC fully upgraded and ready for equipment installation, Aqua Metals is prepared to commence equipment installation and commissioning as well as the buildout of an new adjacent building to enable processing of 7,000 tonnes of black mass feedstock annually. These final steps in commercialization depend upon securing the remaining financing for the CAPEX and G&A funding required to complete the project — and position the Company to become a domestic leader in the closed-loop, clean energy supply chain.

2024 Progress and 2025 Momentum Highlights

Technology Proven, Products Validated

	●	Successfully operated the Li AquaRefining™ pilot for over a year, achieving >99% recovery of lithium, cobalt, and nickel with 83% lower CO₂emissions than hydrometallurgy.
	●	Completed a three-week, 24/7 endurance run of the Li AquaRefining™ pilot in December 2024, demonstrating reliable, continuous performance and readiness for commercial scale-up.

	●	Produced more than 600 pounds of >99.5% pure lithium carbonate — one of the only current U.S.-based sources of battery-grade recycled lithium at this scale.
	●	Supplied AquaRefined high-purity battery grade lithium carbonate to multiple CAM producers for analysis and testing for LFP cell development.

●

Achieved a major U.S. milestone by converting recycled domestic nickel into cathode active material (CAM) with a downstream CAM producer, now under validation by top-tier battery manufacturers in Asia and the U.S.

Commercial Scale in Motion: Sierra ARC

●

Completed key Phase One construction and upgrade milestones at the Sierra ARC facility, intended to enable a rapid transition to accepting black mass for processing and initiating critical mineral production at scale.

●

Expanded initial production scope to prioritize lithium carbonate and mixed hydroxide precipitate (MHP), more than doubling lithium output without significantly increasing capital cost.

●

The updated plan, for which the company continues to seek financing, is designed to reduce capital equipment intensity, shorten time-to-revenue, and deliver a targeted three-year payback — even in a currently challenging strategic battery metals commodity market.

Strategic Partnership Advancements

●

Signed a long-term supply agreement with 6K Energy to provide up to 30% of the recycled content for its domestic cathode manufacturing facility, creating one of North America’s first closed-loop battery material partnerships, pending further financing for both parties.

●

Advanced multiple potential feedstock and offtake agreements to support consistent throughput and strengthen Sierra ARC’s commercial foundation.

●

Exploring licensing and co-location opportunities to extend AquaRefining technology beyond Aqua Metals' owned facilities.

Financial

●

Raised approximately $15 million in equity with insider participation demonstrating internal confidence.

	●	Received a $2.2 million tax abatement from the State of Nevada, tied to the ARC’s projected $392 million economic impact and job creation, as calculated by the Nevada Governor's Office of Economic Development.
	●	Closed $1.5M interim bridge financing in December 2024 — over two-thirds of which was contributed by Aqua Metals’ leadership and Board.

Recognition and Resilience

	●	Selected by the U.S. Department of Energy to join the ACME-REVIVE program, supporting domestic recovery of critical minerals.
	●	Named a “Top Project of 2024” by Environment + Energy Leader for groundbreaking work in clean battery materials.

	●	Recognized by Nevada’s economic development authorities for leadership in sustainability and clean energy job growth.
	●	Recognized as the only finalist in the Lithium loop of Nevada for “Best Places to Work in Northern Nevada Awards” by Northern Nevada Human Resources Association.

●

Strengthened the Board with experienced leaders from the battery and finance sectors to guide commercialization and strategic growth.

“Our team delivered in 2024 — proving and de-risking our technology at the pilot plant, advancing existing and potential commercial partnerships, and preparing for commercialization,” said Steve Cotton, President and CEO of Aqua Metals. “In a year where much of the battery industry has faced delays and headwinds, we adapted with speed and discipline. The result is a more resilient, capital-efficient strategy that positions us to move fast and flexibly.”

“We’ve reimagined how to commercialize our first production facility to meet the realities of today’s strategic battery minerals market while staying true to our long-term vision,” Cotton added. “By prioritizing higher-margin products and deepening strategic partnerships, we believe that subject to securing the additional financing we need, we will steadily progress our path to revenue while building the foundation for a sustainable, closed-loop supply chain in the U.S.”
