Green Technology Metals (ASX:GT1) builds 30Mt lithium platform with Root upgrade

While lithium markets may be facing short-term volatility, Green Technology Metals (ASX:GT1) isn’t waiting for a price rebound to plot its next move.

Instead, it’s gone deeper—literally—at its Root Project in Ontario, delivering a 38% increase in resource and cementing the project’s role as the cornerstone of its vertically integrated lithium vision.

For Managing Director Cameron Henry, the update isn’t just about tonnes—it’s about timing and strategy.

“Root is positioned to provide long-term feed for the Company’s lithium concentrator and underpins further years of feed for our planned hydroxide conversion facility in Thunder Bay,” Henry said.

With a total Mineral Resource Estimate (MRE) now at 20.1 million tonnes at 1.24% Li₂O, Root has overtaken Seymour to become GT1’s flagship asset by tonnage.

That’s no small feat considering Seymour was initially the poster child for GT1’s Ontario ambitions.

The combined Ontario resource base now sits at 30.4Mt at 1.17% Li₂O—firmly placing GT1 in heavyweight territory for Canadian lithium hopefuls.

Highlights:

• Root Bay deposit increased from 10.3Mt to 15.6Mt, including a strong 10.0Mt at 1.32% Li₂O in Indicated category.

• New underground potential unlocked, with high-grade pegmatites RB006 and RB007 extended 400m below surface.

• Thunder Bay hydroxide plant strategy reinforced, with Root’s long-life feed expected to kick off from 2030.

• Standalone PEA for Root due imminently, supporting GT1’s broader downstream integration plan.

The latest resource upgrade follows 14 deep diamond drill holes across 9,130m, confirming the persistence of spodumene-rich pegmatites below the existing pit shell.

Notably, intercepts returned up to 17.6m at 1.44% Li₂O, with the pegmatites still open downdip to the south.

If that sounds familiar, it should—Ontario’s Greenstone belts have been drawing comparisons to Australia’s Pilbara for years.

But GT1’s secret sauce lies not just in geology, but geography.

The proximity to hydropower, rail, and industrial centres like Thunder Bay adds an ESG-friendly dimension that many Australian players can only envy.

Root also offers something rarely discussed in lithium land grabs: geological elegance.

The structural complexity of the stacked pegmatites and their orientation, dipping gently before steepening at depth, suggests a system with room to grow—both laterally and vertically.

As Henry notes,

“The resource growth reinforces our confidence of the area for future additions and highlights the successful interpretation by our Geology team and drilling campaigns.”

This isn’t the lithium story of 2021—frothy with hype and greenwashed PowerPoint decks.

GT1 is playing the long game: build now, produce later, and lock in strategic value when conversion facilities—not just rock—define the next lithium cycle.
