Green Technology Metals Ltd (ASX:GT1) is already looking to the next phase of exploration after releasing a maiden mineral resource estimate (MRE) for its Root Lithium Project in Ontario, Canada.
Based on a cut-off grade of 0.2% lithium oxide, the estimate measures 4.5 million tonnes at 1.01% lithium oxide and 110 parts per million (ppm) tantalum pentoxide.
This takes the company’s overall mineral resources to 14.4 million tonnes across two 100%-owned lithium projects in Ontario with the other resources from the Seymour project about 200 kilometres to the east.
The maiden Root MRE follows five months of drilling that began in August 2022 and focused largely on the McCombe deposit, where 89 holes were drilled covering 14,883 metres.
Drilling also extended to the Morrison and Root Bay deposits, which returned a number of high-grade intercepts and showed significant potential for ongoing resource expansion. However, no drilling at Morrison or Root Bay was included in the MRE.
“This is just the beginning for the Root project and we are very pleased with the outcome of our maiden mineral resource estimate at Root incorporating just five months exploration at our McCombe deposit with further extension potential,” Green Technology Metals chief executive Luke Cox said.
Further resource expansion
While extensional and infill drilling will be required to increase confidence in the Root MRE, Green Technology Metals is also looking to boost exploration efforts at other targets.
A large area surrounding the McCombe, Morrison, Root Bay and Root Lake deposits remains underexplored and highly prospective for new pegmatite targets.
In addition, the McCombe deposit remains open to the east and, according to the company, likely joins the Morrison pegmatites along strike. Diamond drilling in this area is expected to run in conjunction with programs already underway at Morrison and Root Bay.
Further afield, Green Technology Metals plans to use the upcoming field season in Canada to expand its exploration focus to the northern half of the Root project, which was acquired last year and includes 29.9 square kilometres of “prime lithium real estate”.
