Cosigo Resources Announces Results of Conglomerate Layer Bulk Sample for Gravity Concentration Tests

Exploring gold opportunities

Executive Summary

Cosigo Resources released the results of a 60 kg bulk sample taken from the “Chicken Coop” conglomerate at its Taraira (Colombia) project. The Knelson gravity test and screen assay showed a weighted average gold grade of only 0.03 g/t Au. Although the pan concentrate reached 5.21 g/t Au, it represented just 6.9 % of the total gold in the sample, with the majority of gold reporting to the Knelson tails (35.2 %) and pan tails (58.0 %). The geological summary confirms the conglomerate extends ~1,019 m strike, ~5.08 m thickness, and hosts elevated Au over an ~813 m southeastern segment, but the bulk sample indicates low overall grade.

Material Impact

The news reveals a material negative outcome: the bulk‑sample grade is far below the high‑grade channel results previously reported (up to 11.3 g/t Au) and suggests limited economic potential for the conglomerate horizon without costly beneficiation. This contradicts earlier optimism that the Taraira project could host a near‑surface, low‑cost gold resource. Consequently, investor sentiment is likely to deteriorate, potentially triggering a re‑rating of the stock downward.
