- n. An important ore of silver, consisting of the sulphid of silver and antimony.
Other minerals which yield a minor percentage of the total silver produced are the silver-antimony sulphides, pyrargyrite or
It also occurs combined with sulphur (as in argentite), with sulphur and antimony (as in stephanite or brittle silver ore, and in pyrargyrite or ruby silver), and with copper, sulphur, antimony, and arsenic, as in polybasite.
Mineralogical analysis shows that silver is contained, partly or fully, in the silver bearing minerals pyrargyrite, naumannite a directly cyanide soluble silver mineral and selenian miargyrite.
Vortex gold and silver mineralization is associated with a volcanic rock hydrothermal breccia and the silver mineralization is primarily contained within the mineral pyrargyrite.
All holes at Santo Nino encountered broad zones of well developed silicified breccias with widespread pyrargyrite
