The hole was stopped at 383.0 meters in a brecciated rhyolite locally pyritic. |
The mill produced a lead concentrate, a zinc concentrate, and pyritic tailings. |
The upper portion of the sedimentary unit is brecciated and has pyritic chert and graphite horizons. |
Molds and pyritic casts are represented in some sandstone beds but are rare. |
In the northern portion of the project, a sericitized and pyritic gold-enriched shear zone over 37 meters wide was discovered. |
The pyritic ores of iron, including marcasite, pyrrhotite and mispickel, are often taken for gold by the inexperienced. |
