On 4 Aug 2025, NioCorp Developments Ltd. (Nasdaq: NB) filed an 8-K reporting that its 92%-owned subsidiary, Elk Creek Resources Corp. (ECRC), executed a Project Sub-Agreement with Advanced Technology International on behalf of the U.S. Department of Defense (DoD). The Sub-Agreement incorporates a 23 Jul 2025 Base Agreement and supports ongoing work at the Elk Creek Critical Minerals Project in Nebraska.
The DoD will reimburse ECRC for up to ≈US$10 million of eligible costs, payable after specific milestones are reached:
- completion of new drilling operations
- completion of engineering studies for scandium metal, scandium master-alloy and aluminum-scandium master-alloy
- delivery of an updated feasibility study
No equity issuance, debt financing, or earnings data accompanies this filing; the disclosure is limited to Item 1.01 (Material Definitive Agreement).
On 1 Aug 2025, NioCorp Developments Ltd. (ticker NB) filed an 8-K announcing that its wholly owned subsidiary, Elk Creek Resources Corp. (ECRC), closed on the purchase of three land parcels in Johnson County, Nebraska under option agreements signed in 2009 and 2014 with Roger and Nancy Woltemath. The acquisition delivers surface rights to the Woltemath80S parcel and both surface and mineral rights to approximately 1.66 acres of the Woltemath002 parcel.
The aggregate purchase price was about US$2.7 million. At closing the company reduced cash (current assets) by the same amount and capitalized the cost as “land” within non-current assets, producing a neutral impact on total assets. No additional financial metrics, debt financing, or forward-looking statements were disclosed.
The filing reports no other material events or changes to previously reported guidance.
Citadel entities and founder Kenneth Griffin have crossed the 5 % ownership threshold in NioCorp Developments Ltd. (NB) and therefore filed this Schedule 13G.
The filing discloses aggregated beneficial ownership of 3,903,395 common shares, equal to ≈5.4 % of the 72.65 million shares outstanding as cited in NioCorp’s 18 Jul 2025 prospectus. Within this total, Citadel Advisors LLC, Citadel Advisors Holdings LP and Citadel GP LLC jointly report 3,772,972 shares (5.2 %), while Citadel Securities controls 130,423 shares (0.2 %). All voting and dispositive powers are shared; no party reports sole power.
The position is reported under Rule 13d-1(b), signalling a passive investment. Certification language states the shares were “not acquired … to change or influence control.” The stake includes 69 shares issuable upon warrant conversion.
This is Citadel’s first publicly reported ownership above the 5 % threshold in NB, potentially indicating incremental institutional interest, but the filing provides no operational or financial commentary.
