Highland Critical Minerals Targets Summer with Airborne Lithium Search and Arctic Infrastructure Windfall

Highland Critical Minerals begins airborne surveys at Church lithium property; C$50M federal funding for Arctic road and port could unlock its Sy gold project in Nunavut.

Two field campaigns, a freshly trimmed portfolio, and a federal infrastructure cheque worth up to C$50 million — Highland Critical Minerals is entering a season that could reshape its trajectory. The junior miner will begin airborne surveys on its Church lithium property in northern Ontario at the end of May, while its Sy gold project in Nunavut waits in the wings for a logistical revolution that Ottawa is now bankrolling.

The Church property has forced the company back to the drawing board. An earlier mobile-metal-ion soil survey returned no significant lithium anomalies, prompting a shift to radiometric and LiDAR surveys from the air, supplemented by ground sampling — weather permitting. The 5,526-hectare property, consisting of 261 cell claims near Nipigon and about 89 kilometres northeast of Thunder Bay, now hinges on whether the new geophysical data can define drill-ready targets that the soil work failed to identify.

To fund both programmes, Highland raised C$400,000 in April through a flow-through placement. The proceeds are ring-fenced for eligible Canadian critical-minerals exploration spending across both Church and Sy. Investors will receive tax credits by the end of 2026, with the expenditure commitment stretching to the end of 2027.

The second front is Nunavut, where the ground has shifted considerably. On 20 May 2026, Canada’s energy minister unveiled a federal package exceeding C$55 million for Arctic infrastructure and critical-minerals supply chains. Up to C$50 million of that is earmarked for planning and pre-construction work on the Grays Bay Road and Port Project — a deepwater harbour and a 230-kilometre all-season road. Prime Minister Mark Carney referred the project to the Major Projects Office in March, signalling Ottawa’s intent to fast-track development.

For Highland, the link to its Sy property is direct. The four contiguous claims cover 3,345 hectares in the Yathkyed Lake Greenstone Belt, a geological setting comparable to the neighbouring Meadowbank and Meliadine gold mines. More than 40 high-grade gold occurrences have been mapped, with historical surface samples returning grades as high as 38.8 grams per tonne. Until now, the absence of year-round road access and a deepwater port has made exploration and any eventual development prohibitively expensive. The Grays Bay corridor would change that calculus fundamentally.

The company itself is leaner than it was six months ago. In December 2025, Highland spun off its Red Lake gold assets into a separate entity, sharpening its focus to two core holdings: Church for lithium and Sy for gold. The market has taken note — the stock closed at C$0.30 on the Canadian Securities Exchange on 27 May, giving the company a market capitalisation of roughly C$13.6 million. Highland reported a net loss of about C$559,000 for fiscal 2025.

Near-term attention will centre on the Church programme. Success would mean the airborne surveys generate targets that the MMI survey missed, opening the door to a drill campaign. Failure would leave the property reliant on an infrastructure story that, for all its ambition, will take years to realise. In the Arctic, the Grays Bay road is a strategic prize — but it is also a long-term one. The question for Highland’s shareholders is whether the summer data can sustain the momentum that Ottawa’s announcement has already begun to build.
