Did anyone get any of the Chinese gold ore from eBay? free shipping and the rocks were going for less than $5 each.

On the other hand I gave up years ago ever buying anything from Canada again, because it seems to take forever and always costs an arm and a leg for shipping! That's even though we're on the same continent and I can actually see Canada across the Detroit river.

Jinfeng Mine in China

Geology[edit]
The deposit at the Jinfeng Gold Mine is a Carlin-type gold deposit (similar to those found in Nevada) in the "Laizhishan Dome" located in a region known as the "Golden Triangle". The Laizhishan Dome is made up of sedimentary rocks from the Silurian through the Late Triassic periods. The deposit itself is located between five faults, with gold being associated with pyrite and arsenopyrite.[3]
https://en.wikipedia.org/wiki/Arsenopyrite
Arsenopyrite is an iron arsenic sulfide (FeAsS). It is a hard (Mohs 5.5-6) metallic, opaque, steel grey to silver white mineral with a relatively high specific gravity of 6.1.[1] When dissolved in nitric acid, it releases elemental sulfur. When arsenopyrite is heated, it becomes magnetic and gives off toxic fumes. With 46% arsenic content, arsenopyrite, along with orpiment, is a principal ore of arsenic. When deposits of arsenopyrite become exposed to the atmosphere, usually due to mining, the mineral will slowly oxidize, converting the arsenic into oxides that are more soluble in water, leading to acid mine drainage.
The crystal habit, hardness, density, and garlic odor when struck are diagnostic. Arsenopyrite in older literature may be referred to as mispickel, a name of German origin.[4]
Arsenopyrite also can be associated with significant amounts of gold. Consequently, it serves as an indicator of gold bearing reefs. Many arsenopyrite gold ores are refractory, i.e. the gold is not easily liberated from the mineral matrix.
Arsenopyrite is found in high temperature hydrothermal veins, in pegmatites, and in areas of contact metamorphism or metasomatism.
