Tango Lithium Project
Canada

The Project consists of 41 contiguous claims covering 8.64 km of ground with known pegmatite occurrences within the highly prospective Georgia Lake pegmatite field. The Project is located ~2.3 km east of Imagine Lithium’s Jackpot project and ~10 km south east of Rock Tech’s Georgia Lake Lithium Project along the southern shore of Georgia Lake, approximately 31 km south west of the Company’s Gorge Project, 143 km northeast of Thunder Bay, 33 km south of Beardmore, and 20 km south east of Macdiarmid. The property is accessible by following Highway #11 north of Nipigon, turning east onto the Gorge Creek Road and then following well-graded gravel logging roads to the property. With less than 10 km to the High Voltage power lines connected to hydropower provide an opportunity to produce ‘greenlithium’.

Exploration Results

  • The Project is largely underexplored with only 5 drill holes from 1955 to 1957 and a trench sample, referred to as a bulk sample from Island showing in the historic documents, from the same time period weighing 213.2 kg that returned 1.4% Li2O.
  • Three drill holes completed on the Island pegmatite in 1957 to a depth of 22.86 m (75ft), each confirming the presence of albite-spodumene.
  • A heliborne geomagnetic survey completed over a total of 192 line kilometres during three production flights. The survey provides valuable data that will greatly assist in defining target geology and planning further exploration activities in the project area.
  • Ground reconnaissance sampling in November/December 2024 delivered excellent results:

    • 33.4 g/t Ga (44.90 g/t Ga2O3), 1.40% Li (3.01% Li2O)- Sample 599820

Results from the Lab have returned assay results indicating elevated levels of gallium (Ga) and lithium oxide (Li₂O) in several samples. These results provide further insights into the mineralisation potential of spodumene-bearing pegmatites within the project areas. Gallium oxide (Ga₂O₃) grades ranged up to 72.32 g/t, with several samples showing concentrations above 50 g/t. Lithium oxide grades were also significant, with the highest value recorded at 6.85% Li₂O, and multiple samples exceeding 3% Li₂O. The co-occurrence of elevated gallium and lithium values suggests potential for a dual mineralisation system.

The results indicate a consistent presence of gallium and lithium across the sampled area, with spatial clustering of higher-grade samples suggesting localised zones of mineral enrichment. Further analysis will focus on defining the spatial distribution of gallium and lithium across these areas to guide the next phase of exploration.

These findings are a step forward in understanding the mineralisation at Tango and Barbara, with the data being used to refine exploration strategies and prioritise targets for future work.

Future Work Program

The company is actively reviewing and analysing all available historical exploration results to better understand the presence and distribution of gallium & lithium across its Ontario projects. This comprehensive evaluation aims to delineate the key zones of enrichment and potential areas for further exploration.
