Drop Frequency/Avg. drop per hour

Name	Copper	Tin	Iron	Gold	Mithril	Addy	Runite	Clay	Stone	Sand	Silver	Coal	Slate	Stygian	Salt
Drop Frequency				25%			50%						25%	10%
Avg. drop per hour				40.91			81.82						40.91	16.36

Note that these numbers represent a frequency, that's why they sometimes add up to more than 100 in total.
To get percentage values you need to do (frequency / totalFrequency) * 100, i.e. Clay in Desert: (3 / 106) * 100 = 2.83%
