Tsagaan Ders Lithium

Overview

Tsagaan Ders lithium project, 100% owned by Asian Battery Minerals is located in Khuld soum, Dundgobi province, Mongolia. The Project is located about 40 km south of the town of Mandalgobi which lies on the asphalt highway linking the capital city Ulaanbaatar with Dalanzadgad, capital of Omnogobi Aimag and the regional centre serving the Oyu Tolgoi copper-gold mine and the Tavan Tolgoi coal mines. The property is accessed by 270 km of asphalt highway from Ulaanbaatar to Mandalgobi, then by 40 km of gravel road to the site.The licenses are crossed by numerous unimproved roads and tracks, providing access to all parts of the property.
The project has potential to deliver 4-6% of Li2O concentrate in Li-Mica to Middle stream market.

Geology and exploration works:

Tsagaan ders property is covered by Quaternary to Recent alluvium and aeolian sand. Exposure in the north consists of variably metamorphosed supracrustal rocks cut by two mica granite. The Neoproterozoic Oortsog formation comprises limestone/marble, sandstone/siltstone/shale,
and semi-conformable gabbro.
Pegmatitic rocks are composed of orthoclase, quartz, muscovite and tourmaline. The pegmatites often contain high proportions of lithium micas, up to 30-50%. Spodumene (LiAl(SiO₃)₂) has been recognized in the field and was described in one petrographic sample as comprising 10-15% of the rock.
A total of 429 rock chip samples have been collected on an irregular pattern across the exposures of both the two-mica granite and the pegmatitic border zone, and more sporadically in other rock units.
Grab samples within the pegmatitic border zone show highly to very highly elevated values for lithium, rubidium, caesium, and tin.
Preliminary trenching program in 2023 consisting of 1194.5m of excavation in sixteen trenches
Trenching confirmed consistently elevated lithium in zones up to tens of meters wide over lateral distances of hundreds of meters in two areas.
As no drilling has been completed at the Project the depth of mineralisation is unknown.

Mineralization and result:

• 5 km strike with 100-400m wide (NW to SE) greisened granite alteration zone is discovered
• Two-mica granite: lithium range 12 to 7050 ppm, caesium ranged from 1 to 1830 ppm, rubidium ranged from 7 to 2180 ppm, tin ranged from 1 to 4644
• Pegmatitic granite border zone: lithium ranged from 19 to 13,996 ppm, caesium ranged from <1 to 3550 ppm, rubidium ranged from <1 to 4120 ppm, and tin ranged from <1 to 3248 ppm
• 750 m long x 50 m wide (Central zone) and 500 m long x 50 m wide (South zone) targets in the east and grades into two-mica granite.
• Exploration target (grade of 0.2% to 1.0% Li2O)
