NioCorp plans to recover additional minerals from Elk Creek site
NioCorp updated its feasibility study for the Elk Creek mine, projecting gross revenue of more than $37 billion, up from $22 billion in 2022, helped by adding five rare-earth products including dysprosium and terbium oxides. Elk Creek is described as the largest known US niobium source. NioCorp also signed a nonbinding MoU with Lockheed Martin to potentially buy about 16.5 tons of scandium annually and plans an onsite natural-gas microgrid instead of grid power.
How this was made

The 30-second read
Why it matters
The updated feasibility study increases projected gross revenue and expands the rare-earth product slate, while a nonbinding MoU with Lockheed Martin and a power-source change add additional (but not fully committed) catalysts.
Market read
Traders may reprice the probability-weighted value of Elk Creek based on higher projected gross revenue and expanded rare-earth outputs, while monitoring whether the MoU and microgrid plan translate into binding economics.
What to watch
The shift away from grid power to an onsite microgrid could change capex/opex assumptions and schedule risk, which may offset some of the projected economics improvement.
Background
NioCorp is advancing its Elk Creek mine, described as the largest known US niobium source, and is updating project economics and infrastructure plans.
Ticker impact
NioCorp’s updated Elk Creek feasibility study projects gross revenue above $37B and adds dysprosium and terbium oxides to output.
Moderate upside bias on renewed investor focus, with volatility tied to feasibility credibility and financing/offtake follow-through.
The article discloses a specific, quantified upgrade to projected gross revenue and a concrete change to product mix, which can re-rate project value expectations even without a binding contract.
Market effects
Supports the critical minerals and rare-earth supply-chain narrative, potentially improving sentiment toward US-based extraction projects.
Limited direct regional market linkage beyond local mining and development expectations.
Aligns with defense and industrial demand for scandium and rare-earth oxides, reinforcing strategic-materials themes.
Counterpoint
Feasibility-study upgrades can be optimistic; without binding offtake, permitting, and financing clarity, the market may discount the revenue projections.
