Eight critical minerals now sit inside NioCorp's Elk Creek plan, after the company redesigned its processing and mining operation. The redesigned plan has a larger upfront capital bill, driven by the redesign and inflation since the 2022 technical report.
The balance sheet looks much fuller than it did a year ago. Cash rose from $25.6 million to $415.0 million in the twelve months ended June 30, 2026. The number of diluted shares rose from 45.1 million to 117.2 million over the same comparison.
That is the filing's central trade-off: NioCorp has more cash to work with, but the equity base is far larger and the project has become more expensive to build. The company does not present the cash increase as operating progress. Operating cash outflow widened from $10.7 million to $15.9 million.
NioCorp attributes the cash picture to a mix of project spending, corporate costs, financing-related accounting, and interest income. Some of the loss-related items are accounting marks, not cash payments.
"This is primarily due to spending on the 2026 Elk Creek Study, the recognition of non-cash expenses related to share-based compensation and the valuation of the Earnout Shares and Warrant liabilities, and increased compensation expenses, partially offset by interest income."

The annual net loss widened from $17.4 million to $48.6 million, while stock compensation increased from $789,000 to $4.4 million. The warrant and earnout remeasurements belong in the loss, but they do not explain a cash drain; the operating outflow does.
Management also says the higher spending was not simply a bookkeeping effect. Exploration and general and administrative costs increased, with non-cash changes in earnout-share and warrant liabilities offsetting part of the reported operating outflows.
"Overall, operational outflows during fiscal year 2026 increased from fiscal year 2025 primarily due to increased exploration and general and administrative expenditures, offset by non-cash activity related to changes in valuation of earnout shares and warrant liabilities."

The project itself carries another layer of uncertainty. NioCorp says the estimated upfront capital expenditure rose because of the substantially redesigned plan and significant inflationary impacts. The potential EXIM Financing remains subject to due diligence, internal review, final terms, and definitive documents, so the larger cash balance is not the same thing as a fully documented project financing package.
The company's filing also describes a market split for scandium and the heavy rare earths dysprosium and terbium. Prices outside China are significantly higher than inside China because of Chinese export controls, giving the project's eventual economics exposure to both commodity pricing and geopolitics.
NioCorp's next reported period leaves one factual item to add: the status of the EXIM Financing alongside operating cash outflow and the cash balance. For now, the balance sheet is better funded, the project costs more, and the share count is much higher.
More cash, more shares, more capital required. Mining has a way of making three nouns do the accounting.
