Green Technology Metals Limited (ASX: GT1) has obtained positive maiden lithium assay results returned from the Root Bay Prospect at its wholly-owned Root Project, located approximately 200km west of the flagship Seymour Project in Ontario, Canada.
Drilling at the Root Project was initially focussed on the McCombe and Morrison LCT pegmatite systems. GT1’s exploration has now been expanded to the Root Bay prospect, situated 10 km east.
“Root Bay is the third prospect located on the eastern side of the Root Project with drilling now confirming multiple stacked lithium bearing pegmatites cross cutting a magnetic ridge that extends over 6km of highly prospective ground,” CEO, Luke Cox, said.
Root Bay Prospect
The initial drill hole targeted the Root Bay outcrop which is a large ridge of pegmatite rich in coarse grained spodumene crystals striking north-south with an apparent dip to the east. Drilling was completed down dip confirming grade continues with depth (Pegmatite 1) and then several other spodumene bearing pegmatites (Pegmatites 2 and 3) were intersected highlighting a stacked system which is shallower and thicker:
o RB-23-001: 79.7m down dip grade continuity intersections, including:
▪ 67.1m @1.13%Li2O from 60.9m (Pegmatite1)
▪ 7.3m @1.44% Li2O from 162.0m (Pegmatite 2)
▪ 5.3m @1.34% Li2O from 174.3m (Pegmatite3)
“The Root Bay outcrop cross cut’s a regional scale magnetic ridge that strikes east-west for over six km and we believe this is one of the regional structures which controls lithium mineralization in the area,” Mr Cox said.
“Field exploration mapping completed by GT1 in September 2022 located additional spodumene bearing pegmatites to the west of the Root Bay outcrop along strike of the magnetic ridge, these have been followed up with drilling and intersected Spodumene bearing pegmatite with significant widths which is open down dip and along strike:
o RB-23-085: 15.9m @15% Visual Spodumene from 181.4m o RB-23-088: 17.8m @10% Visual Spodumene* from 99.4m o RB-23-091: 14.5m @15% Visual Spodumene from 33.1m.
Drilling has now intersected six separate pegmatites with a multitude of interstitial and interconnecting smaller pegmatites within the initial drill area representing just 1.2km of the available >six km strike length.
Drilling will now step north 100m to complete another fence line to determine strike length of the known pegmatites and test additional breaks in the magnetic ridge before targeting depth extensions and the remaining geophysical targets along the 6km ridge.
The litho-structural interpretation has been successful in providing significant geological information especially on the structural setting of the area and providing eight Priority-0ne target areas for follow up, and an additional 12 Priority-2 and -3 targets.
The interpretation importantly delineates significant shear-zones bounding and internal to the greenstone belts that probably represent multiple deformational phases. The complex magnetic pattern indicates that the internal structure of the greenstones has undergone extensive deformation. Numerous small zones of alteration or possible non-magnetic intrusions have been interpreted throughout the area. Discrete, local zones of demagnetization define local faults, alteration zones, and subtle bends that may represent dilatational zones with potential to host mineralization.
PEA and MRE Update
A Preliminary Economic Assessment (PEA) will be delivered pending the release of the Maiden McCombe Mineral Resource Estimate (MRE) and Seymour MRE Update, this is due to the PEA incorporating feed from the new MRE’s.
Root Project Infrastructure
The Root Project is readily accessible via all-weather roads and airports with emergency response capability in Slate Falls and Sioux Lookout. The Transcontinental railway connects Root and Seymour projects with a direct line and sidings managed by CN Rail. Hydro power lines run through the eastern side of the Root Project electrifying the region with green energy.
