Cosigo Resources samples 5.21 g/t Au at Taraira
Low‑grade bulk sample yields modest gold concentrate, dampening hopes for near‑term value uplift
Cosigo Resources announced Knelson gravity concentration test results on a 60 kg bulk sample from the “Chicken Coop” conglomerate (Taraira project, Colombia).
- Weighted average grade of the bulk sample: 0.03 g/t Au.
- Pan concentrate produced 5.21 g/t Au, representing only 6.9 % of total gold in the sample.
- The majority of gold remains in tails (58 % in pan tails, 35 % in Knelson tails).
- Geological description confirms a ~1 km strike, ~5 m thickness, depth 20‑25 m below historic “Chile” horizon.
- Qualified Person Erik Ostensoe signed off per NI 43‑101.
The test demonstrates that the conglomerate’s gold is poorly liberated; only a small fraction can be recovered by simple gravity concentration. The concentrate grade (5.21 g/t) looks attractive in isolation, but it represents less than 7 % of total Au, implying low overall recoverable metal. Compared with earlier expectations that the conglomerate could host economically viable bulk‑tonnage gold, these results miss the mark and suggest a need for more complex processing or deeper drilling to locate higher‑grade zones. The news is flagged as “Material – Negative” by the issuer, confirming it deviates negatively from prior optimism.
Cosigo Resources Ltd. is a junior gold explorer focused on the Taraira project in Colombia, featuring the “Chicken Coop” conglomerate—a volcaniclastic‑derived, polymictic unit with reported bulk‑tonnage potential. The company also holds exploration rights at Willow Creek (Nevada) and Damian (Colombia). Flagship aim: delineate a low‑cost, gravity‑recoverable gold resource.
