Koba unearths new LCT pegmatites at Blue Moon

After finding new lithium-caesium-tantalum (LCT) pegmatites at its Whitlock Lithium Project in Manitoba, Canada, junior explorer Koba Resources (ASX:KOB) is now gearing up to plan an inaugural drilling program for the area. 

The $14.75 million market capitalisation company has discovered a string of new LCT pegmatites at the Blue Moon prospect within Whitelock, with outcrop and channel sampling at Blue Moon returning assays of up to 3,806 parts per million (ppm) caesium, 731ppm tantalum, 1,498ppm lithium, and 6,259ppm tin.

The results come from three channel samples collected perpendicular to the outcropping pegmatite, with aggregate results for each channel sample including: 3.6m @ 1,135ppm Cs2O, 753ppm Li2O, 107ppm Ta2O5, and 212ppm SnO2; 3.5m @ 1,011ppm Cs2O, 748ppm Li2O, 70ppm Ta2O5, and 174ppm SnO2, and 2.5m @ 921ppm Cs2O, 624ppm Li2O, 174ppm Ta2O5, and 1,501ppm SnO2.

Koba has mapped the stacked pegmatites at Blue Moon over 70m, with an average width of 3m at surface. The company says the pegmatites then disappear under cover. 

The discovery comes after Koba in September 2023 struck lithium-bearing pegmatites at the Lynx prospect in the project area, prompting the follow-up work that led to this new Blue Moon find. 

Koba says Blue Moon lies within a 5km mineralised trend that includes multiple spodumene-bearing pegmatites and, as such, appears to be part of a system with ‘significant scale potential’. 

Koba Managing Director and CEO Ben Vallerine says the Blue Moon discovery marks another ‘exciting development’ for the Whitelock Project.

“LCT mineralisation has now been identified over 5km of strike at and around the Blue Moon prospect — so there is certainly significant potential to discover a sizeable high-grade deposit. 

Koba is progressing plans for both a follow-up sampling program and an inaugural drilling program during the forthcoming Canadian summer.”

“There is certainly significant potential to discover a sizeable high-grade deposit”

Vallerine adds that lithium, caesium, and tantalum are all mined at the nearby ‘high-grade’ Tanco Mine, giving the company confidence that similar high-grade mineralisation can be discovered within the Whitelock area. 

Ahead of the planned drilling work, Koba is planning to conduct stripping, mapping, and outcrop and channel sampling at Blue Moon, as well as work along the entire 5km Koba trend that includes the Blue Moon, Lynx, and Moose prospects.

According to Koba, the Blue Moon area has never been drilled before. 

Koba will also complete further sampling along the previously identified Beaver Tail, Fox, Marmot, and 5 Eagles prospects that lie elsewhere within the Whitelock area.

Kobe Resources had around $4.7 million cash and cash equivalents at hand as of 30 September 2023, according to its latest quarterly report.
