NioCorp (NASDAQ:NB) began official excavation of the Elk Creek Project mine portal in southeast Nebraska on March 4, 2026, with Congressman Adrian Smith and local officials participating.
The portal starts primary access for the planned underground mine; the company projects the project will create over 400 jobs and generate more than $600 million in state and local tax revenue. The orebody targets multiple critical minerals, including niobium, scandium, titanium and several magnetic rare earths.
NioCorp (NASDAQ:NB) has begun construction of the Elk Creek mine portal in southeast Nebraska, launching an approximately $44.6 million effort to create the main underground access. The company filed a Notice of Commencement with MSHA and cites roughly $500 million raised in 2025–2026 to date, which it says strengthens its position with EXIM as it pursues remaining project financing and a final investment decision (FID).
Management expects the portal work to take about nine months and says a formal groundbreaking will follow completion of overall project financing.

NioCorp (NASDAQ:NB) applauded the White House and EXIM for launching Project Vault, a proposed $12 billion U.S. Strategic Critical Minerals Reserve anchored by $11 billion from EXIM and about $1.67 billion in industry seed capital. The initiative aims to procure, store, and sell critical minerals to U.S. manufacturers.
The release cites the Commerce Department's Section 232 findings and a January 14 Presidential Proclamation authorizing trade measures to reduce reliance on foreign-processed critical minerals. NioCorp said it stands ready to advance the Elk Creek Project to supply American-made materials.
NioCorp (Nasdaq: NB) issued a 2025 year‑in‑review reporting major progress toward financing, technical programs, federal support, and pre‑construction readiness for the Elk Creek Critical Minerals Project.
Key 2025 outcomes: raised >$370 million (including $360.8M equity and $10M from the Department of War), ended 2025 with $307M cash, advanced EXIM review to Independent Technical Review, received $6.8M of up to $10M Department of War funding, completed >7,000 assay samples from infill drilling, acquired required land parcels, and approved a mine portal pre‑construction project.
NioCorp Developments (NB) reported final assays from its completed 2025 Elk Creek drilling campaign in Nebraska on January 12, 2026.
The Department of War-funded program produced more than 7,000 drill-core samples. Hole NEC25-028a returned 105.49 meters at 1.58% niobium pentoxide (Nb2O5) and 5.11% titanium dioxide (TiO2). Hole NEC25-029 returned 206.57 meters at 0.88% Nb2O5 and 100.04 parts per million scandium. Hole NEC25-036 returned 72.00 meters at 10,304 parts per million total rare earth oxides. Hole NEC25-026 had no significant results.
The assays are being used to update Elk Creek’s mineral resource and reserve estimates. They are not themselves resource or reserve estimates; further technical work is needed, and higher-confidence classifications cannot be assumed. NioCorp says the updated feasibility study will help the Export-Import Bank of the U.S. complete diligence on its pending debt financing application.
NioCorp (NASDAQ:NB) reported preliminary unaudited results for the three- and six-month periods ended December 31, 2025. The company held a record $307 million cash balance and received up to $10 million from the U.S. Department of Defense for Elk Creek-related activities. Key actions during the period included an Elk Creek infill drilling campaign, acquisition of scandium alloy manufacturing assets, land purchases securing project acreage, and agreements with the DoD and Lockheed Martin on scandium technologies.
Financials: three-month net loss $0.8M (adjusted net loss $5.3M); six-month net loss $43.4M (adjusted net loss $13.6M); operating cash outflows for six months $7.6M. Results are preliminary and unaudited; full 10-Q expected by Feb 16, 2026.
NioCorp (Nasdaq: NB) announced Board approval of a Mine Portal Project at the Elk Creek critical minerals site to establish the main underground mine entrances. Work is expected to begin in Q1 2026 and the current estimated capital cost is approximately $44.6 million. The scope covers excavation to bedrock, drilling and blasting to form twin ramps, on-site access roads, and supporting infrastructure.
The portal will enable implementation of the electric Railveyor™ bulk-handling system (previously announced), replacing a twin-shaft design and aiming to reduce initial capital and shorten pre-development timing. Management said advancing the portal moves a critical-path schedule item forward while the company continues working to secure the remaining financing needed for Elk Creek.
