Seymour, Wisa and Root Lithium Project overview.

35,000 Hectares of prime lithium real estate

GT1 has increased its tenement base from 9,467 hectares to 35,576 hectares with all sites hosting lithium minerals and/or LCT pegmatites.

  • Green Technology Metals has increased its exploration claim holdings in NW Ontario to 35,576 ha (from 9,467 ha original position) via strategic pegging and option agreements. 

  • Newly acquired claims focussed on Seymour and Root, as well as a new project named Allison.

  • Allison is considered one of the most under-explored and prospective areas for LCT pegmatites in NW Ontario.

  • All exploration areas host lithium bearing minerals and/or LCT pegmatites.

The Company has increased its tenement base from 9,467 hectares to 35,576 hectares through execution of multiple option agreements and tenement pegging activities. The new landholdings surround Green Technology Metals' existing projects, Seymour and Root, as well as being in a new project area named “Allison” and select other project areas (Pennock Lake, Root Bay, Superb Lake and Gathering Lake) (see Figure 1).

Note:  The Company currently holds an 80% interest in the Ontario Lithium Projects (Seymour, Root and Wisa) under a joint venture with Ardiden Limited (ASX: ADV). Refer to the Company’s Prospectus (see GT1 ASX release dated 8 November 2021) for further details.


Seymour: As previously announced (see GT1 ASX release dated 8 November 2021, Pre-Quotation Disclosures), GT1 has pegged 439 new mining claims around Seymour for a total addition of 9,029 hectares. This holding extends to the north of Seymour reaching into the Archean Green Stone Belt which hosts locally known LCT pegmatites.

Root: Green Technology Metals has now substantially increased its claim holding around the north-east area of the Root Project (through pegging of a further 2,993 hectares).  This holding now extends to the east reaching into the Archean Green Stone Belt which is prospective for LCT pegmatites and locks up the remaining belt shared with international mining companies exploring for lithium, gold and base metals.

Green Technology Metals has entered binding option agreements with two unrelated parties to acquire claim packages covering 6,968 hectares in the Allison area (see Appendix A for the claim schedules subject to these agreements and Appendix B for the key terms of these agreements). This is in addition to the 125 claims previously pegged in this area for 2,630 hectares (see GT1 ASX release dated 8 November 2021, Pre-Quotation Disclosures).

The Allison Batholith is a multiphase intrusion that is highly prospective for evolved LCT type pegmatites. F.W. Breaks (renowned Ontario Geological Survey geologist responsible for discovery of Avalon’s Separation Rapids Lithium Deposit and instrumental in the early development of Frontier Lithium’s PAK deposit) described the Allison Lake area in 2003;

“The Allison Lake batholith represents an important new exploration target for rare-element mineralization and is the largest such granite thus far documented in Ontario.”


“This area has high potential for further discoveries of rare-element mineralization that could occur in exo-contact, metasedimentary-hosted pegmatites or as internal pegmatites within the parent granite. Only beryl-type pegmatites have been discovered to date, however, in light of the common regional zonation sequence of rare-element pegmatites from beryl-rich into lithium-rich types (Čern ̋ 1991b) (albite-spodumene-type and complex-type) with increasing distance from the parent granite, this corridor is recommended for detailed exploration.”

Pennock Lake, Root Bay, Super Lake and Gathering Lake

GT1 has also entered into an option agreement with Solstice Gold Corporation (CVE:SGC) to acquire 31 mining claims across 4 locations: Pennock Lake, Root Bay, Superb Lake and Gathering Lake (see Appendix B for key terms of this agreement).

Key features of these new project areas include:

  • Pennock Lake: geologically mapped spodumene pegmatites4, source OGS MP053, 1972, directly adjacent to Frontier Lithium PAK and Spark Projects.

  • Root Bay: borders Evolution Mining’s substantial Greenstone land package and along strike of GT1’s Root Project.

  • Superb Lake: hosts rare-element and spodumene bearing pegmatites indicative of fertile peraluminous granites5, source Breaks et al 2006 & 3 MNDM registered rare earth pegmatites, located north-east of Rock Tech and proximate to GT1’s Seymour Project.

  • Gathering Lake: hosts multiple pegmatites, north-east of the Barbara Lake pegmatite field and historical sampling noting fractionation minerals in abundance. 6 Source Breaks, OFR 6120, 6199.


All newly pegged and optioned tenements have been ranked based off prospective geological setting plus any observed pegmatite widths and lithium grades. GT1 plans to undertake a systematic evaluative approach to exploration of these new areas, alongside rapid advancement of its core Seymour, Root and Wisa Projects, in keeping with its focus on building a sustainable, North American focussed lithium production business.
