Constellation Acquisition Corp I reported a net loss of $686,786 for the quarter ended March 31, 2026, driven mainly by $1,955,632 of general and administrative costs, partly offset by a $1,263,996 non‑cash gain from lower warrant liabilities. Cash in the operating account was $5,127, with only $641,254 held in the Trust Account, reflecting extensive prior redemptions.
The company has a working capital deficit of $8,672,879 (excluding a $3,181,000 related‑party convertible note) and discloses that mandatory liquidation by the Termination Date of May 29, 2026, or as late as January 29, 2027 with extensions, raises substantial doubt about its ability to continue as a going concern.
On April 9, 2026, Constellation signed a Business Combination Agreement with HiTech Minerals Inc., based on an equity value of $500 million, and its sponsor affiliate invested $1,550,000 in 12.0% Series A Cumulative Convertible Preferred Stock plus a commitment to purchase $2,500,000 of PubCo equity or equity‑linked securities, aiming to support closing the HiTech Business Combination in the second half of 2026.
Constellation Acquisition Corp. I reposted a LinkedIn presentation from Jindalee Lithium Limited on May 13, 2026 that discusses a proposed business combination among Constellation Acquisition Corp. I ("CSTA"), PubCo (US Elemental Inc.), Jindalee and HiTech Minerals Inc. The parties expect to file a Proxy/Registration Statement on Form S-4 in connection with the Business Combination, which is governed by a Business Combination Agreement dated April 9, 2026. The communication contains customary forward-looking statements and directs shareholders to review the forthcoming Registration Statement and related SEC filings for details.
Constellation Acquisition Corp. I and Jindalee Lithium report that US environmental groups filed a lawsuit in Oregon challenging the US Bureau of Land Management’s 8 December 2025 Decision Record approving an Exploration Plan of Operations (EPO) for the McDermitt Lithium Project. Jindalee, via subsidiary HiTech Minerals Inc., intends to seek intervention to support the BLM’s decision. The company says the EPO authorizes temporary exploration only and does not approve mining operations. No preliminary injunction or court order suspending EPO activities has been filed, and a timetable for the proceedings has not been set. Jindalee cites prior multi-year environmental review and agency engagement, refers to its Pre-Feasibility Study (November 2024), and notes the Business Combination Agreement dated April 9, 2026 among the contracting parties. Jindalee states confidence in the BLM’s analysis and will provide updates as required.
Constellation Acquisition Corp I borrowed $5,000 under an existing unsecured promissory note from Constellation Sponsor LP and deposited the funds into its trust account. This small loan allows the SPAC to extend the deadline to complete its initial business combination from April 29, 2026 to May 29, 2026.
The company describes this as the third of eleven permitted one-month extensions under its amended and restated memorandum and articles of association, giving it extra time to finalize a deal. The note bears no interest and matures when an initial business combination closes, and if no deal occurs, repayment will be made only from funds remaining outside the trust account.

The filing notes that a Proxy/Registration Statement on Form S-4 will be prepared and filed in connection with shareholder voting on the Business Combination and that related proxy and prospectus materials will be mailed after the Registration Statement is declared effective.
