Argenta Silver (TSX-V:AGAG) reports up to 96% silver (Ag) recovery and concentrate grades of 14,857 grams per tonne Ag from initial cleaner flotation tests at its El Quevar Project in Argentina.
The company completed rougher flotation testing across 15 representative variability samples from the Yaxtché deposit, with 13 averaging about 95% Ag recovery. Recoveries reached as high as 99% in multiple samples.
Two samples with contrasting rougher mass-pull responses advanced to cleaner testing.
Sample EQ-VAR-06 achieved 96% overall Ag recovery, with successive cleaning lifting concentrate grade from 6,221g/t Ag in rougher concentrate to 14,857g/t Ag in third cleaner concentrate.
Meanwhile, sample EQ-VAR-15 maintained about 91% recovery, with grade rising from 1,606g/t Ag to 3,364g/t Ag.
CEO Joaquín Marias says the recoveries were achieved in early-stage testwork.
“Achieving silver recoveries of approximately 99% in multiple rougher flotation samples, together with 96% silver recovery in cleaner testing producing a concentrate grading 14,857g/t Ag, is a strong outcome at this stage of the program,” Marias adds.
Blue Coast Research continues testing samples from Yaxtché, including material from the north-west expansion zone. Locked-cycle testing, concentrate characterisation, and optimisation work are expected to complete within 45–60 days.
Argenta has completed more than 25,500m of drilling in 89 holes since May 2025 and expanded its program to 45,000m, with two rigs focused on resource expansion and exploration.
El Quevar spans 57,000 hectares in Salta Province. The Yaxtché deposit contains an indicated mineral resource of 45.3 million ounces (Moz) of Ag from 2.93 million tonnes (Mt) grading 482g/t Ag.
Yaxtché also includes an inferred resource of 4.1Moz from 0.31Mt grading 417g/t Ag.
