Beryllium (Be)
Beryllium: the lightest structural metal
Beryllium is a light, stiff, thermally stable metal used in aerospace structures, defence optics and precision instruments. It is produced by a very small number of operations worldwide, and it is one of the elements that marks a chemically evolved pegmatite system.
Beryllium is about a third lighter than aluminium and substantially stiffer than steel. That combination is why it ends up in satellite optics, inertial guidance and precision instruments, where a component has to hold its shape and cannot afford the weight.
Most beryllium is never used as pure metal. The largest application by volume is copper-beryllium alloy, where a small percentage transforms the copper into a high-strength, non-sparking, non-magnetic material used in connectors, tooling and oilfield hardware.

Based on sales revenues, approximately 29% of beryllium products were used in consumer electronics, 24% in aerospace and defense applications, 17% in industrial components, 9% in automotive electronics, 8% in energy applications, 2% in semiconductor applications, and 11% in other applications.[1]
Supply
A handful of operations, worldwide
Beryllium has one of the most concentrated supply chains of any industrial metal. Global mine production is measured in a few hundred tonnes per year, and the great majority of it comes from a single operation.
Of the 58 mineral commodities included in the Final 2025 List of Critical Minerals (excluding metallurgical coal and uranium), the United States was 100% net import reliant for 13 mineral commodities, and an additional 20 critical mineral commodities (including 14 lanthanides, which are listed under rare earths) had a net import reliance greater than 50% of apparent consumption.[2]
Concentrated production
The United States Geological Survey reports that world beryllium mine production comes from a very small number of countries, with the United States accounting for the majority, followed by China and a limited contribution from other producers. Most United States output comes from bertrandite ore at Spor Mountain in Utah, processed through a single domestic refining and alloy facility.[1]
A narrow processing base
Refining beryllium ore into metal, alloy and oxide requires specialised hydrometallurgical and powder metallurgy capability, and only a handful of facilities worldwide operate it. Because production is small, closely held and technically demanding, published price and volume data are thinner than for most metals, and buyers of beryllium products are exposed to disruption at very few points.[1]
Why Western supply matters
That combination has pushed Western governments and manufacturers to look for additional sources, including beryl-bearing pegmatites in stable jurisdictions. Beryl in hard-rock pegmatite is not currently a major commercial source of beryllium in North America, and it should not be presented as one. Its practical significance for explorers is twofold: it is a potential future feedstock, and it is a reliable geological indicator. In the lithium-cesium-tantalum (LCT) pegmatite family, beryllium enrichment marks the point where a pegmatite system begins to fractionate away from its parent granite, and its presence helps map the path toward the more evolved tantalum, cesium and lithium bearing zones.

A small market the defence base cannot do without
United States beryllium consumption was 230 tons in 2025, worth about $360 million.[1] Close to a quarter of it went into aerospace and defence applications.[1]
Two hundred and thirty tons sounds like nothing. Try building a satellite without it.

Canada was a major supplier of 16 of these mineral commodities, including 4 for which Canada was the leading supplier.[2]
At White Willow
What the filed work shows at White Willow
The White Willow Property in northwestern Ontario hosts beryl-bearing granitic pegmatites. Beryllium occurs there primarily as beryl, and it forms part of the indicator mineral assemblage that places the system at the evolved end of the LCT pegmatite sequence.
The highest beryllium figure associated with the property was reported by Grid Metals Corp, a prior operator, from its 2022 prospecting at the Maple Leaf Dyke. That work returned a value of 5,000 ppm beryllium from a selective grab sample. Grab samples are selective by nature and are not representative of the mineralization hosted on the property. The result is disclosed here as a historical, third-party result attributed to Grid Metals Corp, and it is not presented as a result generated by Totec Resources.
At the Bingo showing, white beryl is one of four indicator minerals observed in the field, alongside spessartine garnet, blue-green apatite and tantalite. That assemblage is the signature geologists expect from a highly fractionated LCT pegmatite, and it is the reason the beryllium occurrence at White Willow is treated as a vectoring tool as much as a commodity in its own right.

White Willow is an LCT pegmatite property in Ontario carrying lithium, cesium and tantalum, with beryl present across both the Maple Leaf and Bingo showings. Beryllium is treated as an indicator of a fractionated, fertile system rather than as a stand-alone target.

Common Questions
Frequently asked
What is beryllium used for?
Beryllium is exceptionally light and stiff, with the highest specific stiffness of any structural metal, and it is transparent to X-rays. That combination puts it in aerospace structures, satellite optics, inertial guidance systems, X-ray windows and nuclear applications. Copper-beryllium alloys, which are non-sparking and non-magnetic, are used in tooling for hazardous environments and in high-reliability electrical contacts.
Where does beryllium come from?
Mine supply is unusually concentrated in a very small number of operations, with the United States historically supplying the majority of world production from bertrandite ore. Beryl, the mineral more familiar as emerald and aquamarine, is the other principal source and is the form in which beryllium occurs in granitic pegmatites.
What is beryl?
Beryl is a beryllium aluminium silicate. Its gem varieties are emerald and aquamarine, but as an industrial mineral it is the beryllium-bearing phase found in granitic pegmatites. Its appearance in a pegmatite marks the first of the rare-element zones in the LCT fractionation sequence.
