Green Technology Metals Limited (ASX: GT1) (GT1 or the Company) is pleased to provide further assay results from the Phase 1 diamond drilling program at its Seymour Lithium Project in Ontario, Canada.
HIGHLIGHTS
- Assays received for further seven holes from Phase 1 step-out diamond drilling of North Aubry deposit at GT1’s flagship Seymour Lithium Project.
- Additional thick, high-grade extensional intercepts of North Aubry deposit including:
- GTDD-22-0001 for 10.5m @ 1.77% Li2O from 123.2m (incl. 7.0m @ 2.11% Li2O)
- GTDD-22-0013 for 18.2m @ 1.10% Li2O from 304.2m (incl. 3.1m @ 2.05% Li2O)
- GTDD-22-0014 for 4.5m @ 0.61% Li2O from 250.7m (incl. 2.5m @ 1.01% Li2O)
- Further northern step-out drilling of North Aubry deposit commenced; hole GTDD-22-0320 intercepts 10.7m of pegmatite with significant visible spodumene (assays pending), extending the known North Aubry pegmatite a further 150m down-dip from the nearest intercept.
- Results from Phase 1 drilling (assays now returned for all 16 holes) indicate substantial potential upside to existing Seymour Mineral Resource estimate of 4.8 Mt @ 1.25% Li2O 1 .
- Updated Mineral Resource estimate for Seymour on track for completion during Q2 CY2022.
- No significant lithium intercepts >1.0% Li20 were returned from initial exploration drilling of the eastern Central Aubry zone (7 holes) and Pye prospect (6 holes).
- Drilling is targeted to resume from June at both Central Aubry (western) and Pye (targeting LCT�type pegmatites of over 250m strike that were identified in the initial drilling).
“In total, the Phase 1 drilling program at Seymour has been highly successful. The results are expected to drive a substantial increase to the existing Seymour resource this quarter. We are also pleased to have commenced further northern and down-dip extensional drilling of the North Aubry pegmatite so rapidly. The initial result from hole GTDD-22-0320 offers further immediate potential to positively impact on mineralised pegmatite extents and volume.” - GT1 Chief Executive Officer, Luke Cox
Further significant step-out intercepts at North Aubry
The Phase 1 drilling program at Seymour was designed to evaluate potential along-strike and down-dip extensions of the North Aubry deposit that were open and untested. The final program consisted of 16 diamond drill holes for a total of 5,826 metres.

All but one hole in the Phase 1 program intersected pegmatite along strike and down dip (refer GT1 ASX release dated 28 April 2022) with the single hole barren of pegmatite, GTDD-22-011, on the southeast flank of the deposit, marking the southerly limit of the North Aubry pegmatites. The intercepts returned from solely the upper pegmatite at North Aubry range in thickness up to 42.7m, with the widest intervals located in the northern extensions of the deposit.
Assays have now been returned for all 16 of the holes drilled in the Phase 1 program.
Significant assay results from the seven further holes that were recently received are detailed in Table 1 (along with details of the previously released intercepts also). The key intercepts were:
- GTDD-22-0001 for 10.5m @ 1.77% Li2O from 123.2m (incl. 7.0m @ 2.11% Li2O)
- GTDD-22-0013 for 18.2m @ 1.10% Li2O from 304.2m (incl. 3.1m @ 2.05% Li2O)
- GTDD-22-0014 for 4.5m @ 0.61% Li2O from 250.7m (incl. 2.5m @ 1.01% Li2O)
- GTDD-22-0002 for 9.0m @ 0.68% Li2O from 174.0m
