is the grade of ore in ground is the grade of waste rock is the dilution (a value between 0 to 1) The same unit must be used for all grades in this equation. Table 1 shows the effect of 10% dilution on ore grade for a gold mine for one tonne of ore. Assaying showed that waste rocks have a small amount of gold.
In most gold bearing veins, the gold does not form into welldeveloped crystals. Unlike quartz which often forms good crystals, gold requires a very specific set of circumstances to grow into good crystal shapes. Few gold deposits produce good crystal specimens, as most gold forms naturally as irregular masses and lumps.
The respawn rate of the gold ore is the same as that of the gold rocks. If you have finished the Shilo Village quest, then this is the best place on Karamja to mine gold.

As initially pointed out by Phillips et al. (1996) for the Kalgoorlie Goldfield, followed by Groves et al. (2016) for orogenic gold deposits generally, it is the conjunction of the above repetitive factors that determines the efficiency of orefluid infiltration in orogenic gold systems and the quality of the gold ores deposited. For example ...
Pyrite is sometimes called Fools Gold because of its similarity in color and shape to the old mining days, Pyrite was sometimes mistaken for Gold, as they frequently occur together, although Gold and Pyrite can very easily be distinguished by simple observation and testing of characteristics.
Natural gold nuggets and specimens as shown here on this web page are normally in the range of 80 to 90 percent gold (roughly 2023Kt). And by far most gold was formed in particles so small that they can''t easily be seen by the human eye, visible only under a microscope, so these large natural chunks shown here are very rare indeed.
