Macarthur Minerals’ ( MIO ) investment company Infinity Mining ( IMI ) has discovered additional lithium pegmatites at the Tambourah South apartment complex in Western Australia’s Pilbara region.
The company, which owns 21.65 percent, received another 31 rocking results and 223 geochemical sampling results on the west side of South Tambur.
The new results of crushed stone samples peaked at 1.77 percent lithium oxide, with three samples containing more than one percent. The company also saw rubidium values in seven samples showing more than 0.2 percent rubidium oxide and a maximum grade of 0.52 percent.
Infinity noted that rock samples also show anomalous lithium indicator geochemistry with up to 9,410 parts per million (ppm) beryllium, 431.3 ppm cesium, 159 ppm niobium and 250 ppm tantalum.
Regarding the sample lag results, two samples recorded more than one percent lithium with a maximum content of about 1.2 percent. Fifteen lag samples yielded values greater than 0.1 percent lithium.
Two areas were identified around known pegmatites in the southern part of the northwest corner of the high-rise building, and a third but weaker zone of “plematic” geochemically enhanced lithium oxide greater than 0.05 percent was seen to the north.
Infinity Lithium said the backlog results indicate that pegmatites may be more widespread than previously thought, and further analysis is underway.
The company aims to develop an exploration method to better identify poorly exposed lithium-bearing pegmatites, and then apply the method to a wider area of apartment buildings to discover additional lithium pegmatite bodies.
Infinity has also received approval for a 2,500m recirculation drilling program testing the depth extension of the mapped pegmatites.
MIO shares were flat at 15 cents, while IMI traded 4.76 percent lower at 20 cents at the market close.
