Collective Mining reports up to 74% tungsten recovery in Apollo metallurgical tests

Copper sub-domain tests delivered 95% copper recovery, 90% gold, and 94.4% silver, producing a 27.2% Cu concentrate.

Tungsten test work achieved up to 74% recovery; bulk-sample concentrate contained 95% scheelite.

The company said copper and tungsten output is expected mainly from higher-grade sub-domains, while most remaining ore routes through cyanidation for gold-silver doré.

Collective Mining said metallurgical test work on the Apollo deposit advanced a dual-route processing flowsheet to support a planned 2027 Colombia licensing submission.

Test work on the Apollo master composite showed 95% gold recovery, 92% silver, and 85% copper, with cyanide consumption of 0.57 kg/t.
