Hoidas Lake

Hoidas Lake is a rare earth exploration project in northern Saskatchewan, Canada, about 55 kilometers northeast of Uranium City (Micon technical report, December 2024). REalloys holds it through Strategic Metals Development, a wholly owned subsidiary it acquired on May 29, 2024 (REalloys 10-Q, August 2026). As of that August 2026 filing, Hoidas Lake is an exploration-stage property with no mineral reserves, and REalloys says it has the potential to be a long-term North American source of rare earth materials (10-Q).

Hoidas Lake geology: rare earths in apatite and allanite veins

The deposit sits in the southern Rae Sub-Province of the western Churchill Province. Its rare earths occur in structurally controlled veins of diopside, hyalophane, apatite and allanite, and the Hoidas-Nisikkatch Fault runs alongside the mineralized zone (Micon). A 2010 Geological Society of America abstract names allanite-(Ce) and fluorapatite as the main rare earth hosts, with minor monazite, bastnäsite and chevkinite-perrierite. It reports that light rare earths (neodymium, cerium and lanthanum) dominate the main JAK Zone (Halpin et al., GSA, 2010).

Krisztina Pandur's University of Saskatchewan doctoral thesis found that the veins formed after peak metamorphism in the area, with titanite ages of about 1,900 and 1,830 million years (Pandur, 2015). A 2020 metallurgical study describes the rare earths as split about equally between apatite-bearing and allanite-bearing veins and says the deposit contains a significant amount of heavy rare earths, such as dysprosium (Anderson and Miranda, 2020).

Hoidas Lake ownership and status (as of October 2026)

The allanite showing was found in 1950 by Jack Lane (Saskatchewan Mineral Deposit Index). Great Western Minerals Group trenched and sampled the property in 1999 and first drilled it in 2001; a 2007 drilling program took a 13.8-metric-ton sample for pilot-plant testing (Micon). Barr Engineering completed a resource estimate for Great Western in 2014 (Barr Engineering).

As of October 2026, Saskatchewan's deposit index lists Star Minerals Group and Mont Strategies as companies for the deposit; the entry carries no update date. REalloys' August 2026 quarterly filing names Strategic Metals Development as the 100% owner (SMDI; 10-Q). REalloys completed its merger with Blackboxstocks on February 24, 2026, and trades on Nasdaq as ALOY (merger release, February 2026).

The property covers 14 contiguous claims totaling 12,522 hectares. They remain in good standing through assessment credits, with minimum spending deferred to dates between October 2027 and June 2029, and the property carries a 1.8% net smelter return royalty capped at C$1 million (10-Q). The site is reached seasonally by ski- or float-equipped aircraft (Micon).

The 2024 technical report said REalloys believed its planned work would let it conduct pilot mining and take a 30,000-metric-ton bulk sample for the Saskatchewan Research Council (SRC). The report also said REalloys would continue talks with SRC to finalize the scope of toll processing (Micon). REalloys' August 2026 filing says the project still needs multi-year spending on drilling, metallurgical testing, environmental and engineering studies, Indigenous and community engagement, permitting, and pre-feasibility and feasibility studies (10-Q).

Why Hoidas Lake matters for REalloys' supply chain

In July 2025 REEx reported that REalloys planned to source inputs for its SRC partnership from Hoidas Lake, recycled magnets and other concentrate streams (REEx, July 4, 2025). REEx later wrote that REalloys "does bring upstream Hoidas Lake resources plus a downstream magnet-materials footprint in Ohio," while naming feedstock logistics among the execution risks (REEx, December 8, 2025). The August 2026 filing says SRC will supply REalloys with rare earth oxide and metal products, and that REalloys intends to source feedstock for SRC from third parties before Hoidas Lake is developed. It adds that Hoidas Lake cannot yet meet REalloys' feedstock needs and may never be able to (10-Q).

By mid-2026 REEx listed Hoidas Lake as a potential future Canadian mineral source and argued that REalloys' valuation depends mainly on whether SRC can deliver commercial-scale separation (REEx, July 18, 2026). Reviewing the second-quarter filing, REEx noted that REalloys' funding excludes Hoidas Lake mine development beyond the current study program (REEx, August 14, 2026). For now the deposit is a future feed source on paper, and the near-term test sits at SRC.
