Do a search for gold and quartz, and you may find gold on milky quartz masses (rough "snow" quartz), but not flakes or tiny nuggets in fully formed clear quartz crystals. As golden metallic inclusions in quartz are almost always pyrite (fools gold), we tested ours at the Birmingham Assay office to confirm they were indeed gold.

From a metallurgical standpoint, gold ores may be roughly classified as (1) simple oxide ores containing fine particles of native gold in a quartz or limestone gangue, (2) simple sulfide ores in which the gold is associated with minor amounts of pyrite or arsenopyrite, (3) placer or alluvium material, (4) complex or refractory ores in which the gold-bearing mineral species are not readily

The pyrite contains the gold. In the gold-bearing region of Northern Sonora, Mexico, the gold-veins are chiefly in or closely associated with granitic and plutonic rocks. The veins of El Grupo concession, about 100 miles southeast of Tucson, Arizona, traverse a fine-grained granite, and hear both gold and silver.

Gold mineralization is within a relatively weak quartz vein stockwork with a low sulphide content (mainly pyrite and pyrrhotite). Approximately 200 metres north of the M Zone, the North Walter Lake Zone (“NWLZ”) is in a zone of high strain with deformed quartz veins within pillowed to massive mafic volcanic flows.

Pyrite (fool’s gold) is yellow but has a dark colored streak, as does chalcopyrite. Gold, which has a color similar to pyrite’s (in hand specimen), has a yellow-gold streak. Mineralogists routinely use streak when identifying minerals, both in the laboratory and in the field, but it cannot be determined for minerals harder than the hardness of a streak plate.

Gold mineralization in the deposit area and the broader district is dated mainly at 310–280 Ma (Naumov et al., 2012) and is represented largely by two types: (1) auriferous sulfides (pyrite, arsenopyrite) in tectonized zones of carbonaceous rocks, and (2) free native gold in quartz veins occurring close to granodiorite-plagiogranite stocks (e.g., Dyachkov et al., 2018).
