Chile-focused Kairos Capital Corporation (TSX:KRS) unveiled what it called "highly significant" assays from its Coipasa and Turi Salar lithium properties.
The firm is focused on developing mining claims in the South American country.
Salar Coipasa lies on the Bolivian border and has the same geology as the lithium enriched Salars de Maricunga and Pedernales in Chile and Salars Olaroz and Cauchari in Argentina, part of the so-called "lithium triangle" of South America.
Salar Turi is 75 km north of the Salar de Atacama, which notably provides around 30% of the world's lithium production - also in the triangle.
The latest results come from both brine and salt samples directly at surface and within 1.5m below. Thus far, sampling has covered around 20% of the 113 sq km Coipasa claims and about 25% of the 61 sq km Turi claims.
Terry Walker, the firm's vice president of exploration, said: "These second round of results include lithium concentrations that are similar to the production grades at the Salar de Atacama and therefore re-inforce management's belief that that the acquired lithium claims have excellent potential."
Surface brine lithium concentrations from the west central and south east flanks at the Coipasa salar range from a low of 297 mg/l (miligrams per litre) to a high of 1410 mg/l and average 615 mg/l over a combined area of 9 sq km, the firm said.
Meanwhile, Salar Turi is 75 km north of and within the same geological and physiographic zone as the Salar de Atacama, the source of around 30% of the world's lithium production - also in the triangle.
