Maximizing Your Mining Profits Options

[Saffy]

I had stumbled upon some mining details while browsing Ushi No Tane recently. Seeing the probabilities for refining and the cost of each possible outcome, I figured I could calculate on average what refining will produce. My results show that the wonderfuls (particularly white) are the only items worthwhile.

For each item I have listed its selling price before refining along with the math showing its price when refined. If a value is negative then it means you're going to lose money on average for refining it.

For clarification, I am calculating an expected rate of return for refined items. I multiply the probability of each outcome by its selling price, add them all up, and subtract the refinery fee of 35G.

Junk Ore = 10G

Junk Ore Refined
= 1*(Junk) - 35
= 10 - 35
= -25G

--

Iron Ore = 20G

Iron Ore Refined
= 0.5*(Junk) + 0.5*(Iron) - 35
= 0.5*10 + 0.5*50 - 35
= 5 + 25 - 35
= -5G

--

Copper Ore = 30G

Copper Ore Refined
= 0.6*(Junk) + 0.4*(Copper) - 35
= 0.6*10 + 0.4*70 - 35
= 6 + 28 - 35
= -1G

--

Silver Ore = 40G

Silver Ore Refined
= 0.7*(Junk) + 0.3*(Silver) - 35
= 0.7*10 + 0.3*100 - 35
= 7 + 30 - 35
= 2G

--

Gold Ore = 50G

Gold Ore Refined
= 0.85*(Junk) + 0.15*(Gold) - 35
= 0.85*10 + 0.15*150 - 35
= 8.5 + 22.5 - 35
= -4G

--

Rare Ore = 150G

Rare Ore Refined
= 0.9*(Junk) + 0.1*(Rare Metal) - 35
= 0.9*10 + 0.1*240 - 35
= 9 + 25 - 35
= -1G

--

Red Wonderful = 30G

Red Wonderful Refined
= 0.75*(Glass) + 0.2*(Garnet) + 0.05*(Ruby) - 35
= 0.75*10 + 0.2*270 + 0.05*830 - 35
= 7.5 + 54 + 41.5 - 35
= 68G

--

Yellow Wonderful = 30G

Yellow Wonderful Refined
= 0.75*(Glass) + 0.2*(Amber) + 0.05*(Topaz) - 35
= 0.75*10 + 0.2*250 + 0.05*550 - 35
= 7.5 + 50 + 27.5 - 35
= 50G

--

Green Wonderful = 30G

Green Wonderful Refined
= 0.6*(Glass) + 0.2*(Peridot) + 0.15*(Jade) + 0.05*(Emerald) - 35
= 0.6*10 + 0.2*350 + 0.15*190 + 0.05*690 - 35
= 6 + 70 + 28.5 + 34.5 - 35
= 104G

--

Blue Wonderful = 30G

Blue Wonderful Refined
= 0.6*(Glass) + 0.2*(Lapis Lazuli) + 0.15*(Aquamarine) + 0.05*(Sapphire) - 35
= 0.6*10 + 0.2*300 + 0.15*420 * 0.05*620 - 35
= 6 + 60 + 63 + 31 - 35
= 125G

--

Purple Wonderful = 30G

Purple Wonderful Refined
= 0.7*(Glass) + 0.2*(Spinal) + 0.1*(Amethyst) - 35
= 0.7*10 + 0.2*220 + 0.1*420 - 35
= 7 + 44 + 42 - 35
= 58G

--

White Wonderful = 30G

White Wonderful Refined
= 0.6*(Glass) + 0.2*(Crystal) + 0.15*(Opal) + 0.05*(Diamond) - 35
= 0.6*10 + 0.2*170 + 0.15*330 + 0.05*1330 - 35
= 6 + 34 + 49.5 + 665 - 35
= 719.5G

I really don't like mining..ever...I'm not sure why.

At least I know which wonderfuls to bother with now though.
