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

Or if you go for White wonderfuls. A stack of 99 can bring in quite the haul.

Mining in ToT was so much more profitable 'cause you could tell what was gonna turn into what when you got it refined. Also refining was free. >[ But ores and wonderfuls didn't stack in ToT, and I hated that. :[

I love mining; it's usually one of my favorite minigames.
