**US Elemental Files Form S-4 Registration Statement in Connection with Proposed Business Combination with HiTech Minerals and Constellation Acquisition Corp. I** 

 

*Filing Marks Key Milestone Toward the Proposed Listing of US Elemental Inc. on Nasdaq Under the Ticker Symbol "ULIT"*

 

**New York, New York, June 4, 2026** – HiTech Minerals Inc. ("HiTech Minerals"), a wholly owned subsidiary of Jindalee Lithium Limited ("Jindalee") (ASX: JLL), and Constellation Acquisition Corp. I ("Constellation") (OTCPK: CSTAF), a special purpose acquisition company sponsored by affiliates of Antarctica Capital, LLC ("Antarctica"), today announced that they have filed a registration statement on Form S-4 (the "Registration Statement") with the U.S. Securities and Exchange Commission (the "SEC") in connection with their proposed business combination. This filing marks an important milestone toward the closing of the proposed business combination and anticipated listing of US Elemental Inc. ("US Elemental" or the "Company") on Nasdaq under the ticker symbol "ULIT."

The proposed business combination, which was announced on April 9, 2026, would result in HiTech Minerals becoming a wholly owned subsidiary of US Elemental, a newly formed U.S. lithium development company. Upon closing, US Elemental will hold the McDermitt Lithium Project in Oregon, one of the largest potential lithium resources in the United States with a mineral resource estimate of approximately 21.5 million tonnes<sup>1</sup> of lithium carbonate equivalent (LCE) as well as the Clayton North Project in Nevada.

The proposed transaction is expected to position US Elemental to advance large-scale domestic lithium resources at a time of increasing demand for critical minerals within the United States and if completed, would provide access to U.S. institutional investors and capital markets through a Nasdaq listing.

**Ian Rodger, Chief Executive Officer of Jindalee and incoming Chief Executive Officer of US Elemental, commented:**

"The filing of the Form S-4 represents a significant step forward in our process to establish US Elemental as a publicly listed U.S. company. We believe this milestone reflects the strength of the McDermitt Project and the team's commitment to bringing what we view as one of the most compelling domestic lithium assets to U.S. investors. We look forward to continuing to advance this process and sharing more details as they become available."

**Chandra Patel, Chairman and Chief Executive Officer of Constellation and Managing Partner of Antarctica Capital, added:**

"We are pleased to reach this important milestone in the path toward closing. The filing of the S-4 is a key step in our timeline and reflects the continued collaboration across all parties. We remain focused on executing the next phases of this process and delivering on our commitment to create long-term value for shareholders."

**TRANSACTION OVERVIEW**

The proposed business combination implies a pro forma enterprise value of approximately $576 million. Under the terms of the definitive business combination agreement:

● HiTech Minerals will become a wholly owned subsidiary of US Elemental;

● Jindalee is expected to roll 100% of its equity interest in the U.S. assets and retain approximately 80% or more of US Elemental following closing, subject to customary adjustments including shareholder redemptions and additional financing;

● The transaction contemplates a capital raise of approximately $20–30 million, including a $4 million PIPE investment from affiliates of Antarctica Capital;

● The combined Company is expected to have approximately $15 million of cash on the balance sheet at closing, after transaction-related expenses.

The transaction is expected to close in the second half of 2026, subject to regulatory and customary closing conditions, including approval by shareholders of both Constellation and Jindalee.

**FORWARD LOOKING STATEMENTS**

Certain statements included in this press release are not historical facts but are forward-looking statements, including for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "expect," "should," "would," "plan," "project," "forecast," "predict," "potential," "seem," "seek," "future," "outlook," "target," and similar expressions that predict or indicate future events or trends or that are not statements of historical matters, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements include, but are not limited to (1) statements regarding estimates and forecasts of financial, performance and operational metrics, projections of market opportunity, anticipated size of the lithium resources, expected support from Jindalee, expected NPV or post-tax IRR, and planned production per year; (2) references with respect to the anticipated benefits of the Transaction and the projected future financial and operational performance of the Company following the Transaction, which may be affected by, among other things, competition, the ability of the Company to grow and manage growth profitably, maintain relationships and retain its management and key employees; (3) the sources and uses of cash of the Transaction; (4) the anticipated capitalization and enterprise value of the Company following the consummation of the Transaction; (5) statements regarding the Company's operations following the Transaction; (6) the amount of redemption requests made by Constellation's public shareholders; (7) current and future potential commercial relationships; (8) plans, intentions or future operations of the Company or HiTech Minerals, including relating to the finalization, completion of any studies, feasibility studies or other assessments or relating to attainment, retention or renewal of any assessments, permits, licenses or other governmental notices or approvals, or the commencement or continuation of any construction or operations of plants or facilities; (9) the ability of the Company or Constellation to issue equity or equity-linked securities in the future or raise additional capital in a PIPE financing; (10) the outcome of any legal proceedings that may be instituted against Contracting Parties; (11) changes to the proposed structure of the Transaction that may be required or appropriate as a result of applicable laws or regulations; (12) the ability to meet stock exchange listing standards following the Transaction; (13) the risk that the Transaction disrupts current plans and operations of the Constellation, the Company or HiTech Minerals; (14) the availability of federal, state or local government support, and risks related to extensive regulation, compliance obligations and rigorous enforcement by federal, state, and non-U.S. governmental authorities; and (15) expectations related to the terms and timing of the Transaction and the ability of the parties to successfully consummate the Transaction. These statements are based on various assumptions, whether or not identified in the press release, and on the current expectations of the Contracting Parties' management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of the Contracting Parties. These forward-looking statements are subject to a number of risks and uncertainties, as set forth in the section entitled "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements and Risk Factor Summary" in Constellation's Annual Report on Form 10-K for the year ended December 31, 2025 (the "Annual Report"), the section entitled "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements" in the Registration Statement and in those other documents that Constellation has filed, or that the Company and Constellation will file, with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. The risks and uncertainties above are not exhaustive, and there may be additional risks that none of the Contracting Parties presently know or that they currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward looking statements reflect relevant Contracting Parties' expectations, plans or forecasts of future events and views as of the date of the press release. Each of the Contracting Parties anticipate that subsequent events and developments will cause those assessments to change. However, while the Contracting Parties may elect to update these forward-looking statements at some point in the future, each of the Contracting Parties specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing any of the Contracting Parties' assessments as of any date subsequent to the date of the press release. Accordingly, undue reliance should not be placed upon the forward-looking statements.
