Based on imaging, EDS, and electron diffraction data collected from the two samples, it was concluded that arsenopyrite
oxidation leads to the precipitation of the amorphous Fe-As-O coating.
grades between 98% and 62% for arsenopyrite
recoveries of 45% to 73%, respectively.
0x20 The gold mineralization occurs as quartz-arsenopyrite
-pyrite-chalcopyrite veins in quartz monzonite and hornfels and as silicification with disseminated arsenopyrite
in quartz monzonite.
The area underwent minor exploration for SEDEX style silver-lead-zinc mineralization in the early 1980's, and previous operators discovered zones of disseminated to fracture controlled arsenopyrite
- sphalerite - galena mineralization within chert, anomalous silver, lead, and zinc in soil samples, and a zone of massive barite up to 20m thick traceable over 5.
Past work by previous operators has identified several mineralized zones of copper and cobalt, and numerous other exploration targets on the property that have not as yet been evaluated, including the arsenopyrite
gold zone mentioned above.
52 meters, -- A section of altered, sericitized and silicified sheared mudstone with traces of pyrite and arsenopyrite
The silicified structures are mineralized by arsenopyrite
and flanked by broad zones of lower grade gold mineralization averaging +0.
3 ft) of disseminated and to a large degree semi-massive sulphides composed of varying concentrations of pyrrhotite, arsenopyrite
and minor pyrite.
, and wolframite are commonly associated with the quartz veins.
Subsequent holes will test the Albitite and Arsenopyrite
Zones further down plunge to the west.
Typical gold-bearing rhyolite is mylonitized, silicified and contains disseminated to stringers of arsenopyrite
The gold is refractory, as it is closely associated with and included or encapsulated inside the arsenopyrite
