IVR share price as Silver rises

With Silver possibly following Golds recent rise, what do we punters think the effect on the value of each share will be for each $1.00 Australian rise in the price of Silver ?

heres my suggestion, but please add your own

we're at .04 cents with a Silver price of currently $35.
Lets work on a value of $30.00 an ounce after processing and mining costs and leave the lead out to cover some of that and inflation as well.
Lets say there's roughly 1,500,000,000. Shares, plus options.
lets multiply the 50,000,000 ounces of silver by the $ 30.00, gives us $ 1,500,000,000 in nominal value over the life of the mine and at that the market currently thinks we are worth .04 cents per share.

So every $ 1.00 rise should be cream.

So each dollar rise is approximately $ 50 million dollars more in value over the life of the mine, (which I think is seven years.)

So you divide the $50,000,000 dollars in increase for each$ 1.00 rise in Silver by the 1,500,000,000 shares to get the increased value per share over the life of the mine.

$ 50,000,000 ÷ 1,500,000,000 shares = .03333 per share and .33 cents per share rise for a rise from $ 30.00 per ounce to $ 40.00 per ounce (over the life of the mine)
So divide by 7 for yearly value increase.
in a market where we are not yet producing lets divide that. 33 cents by seven but then multiply by 2 as an estimate of market sentiment percived value.

so for $10.00 per ounce Australian increase in Silver it's
( .33 cents ÷7) x 2= .094
cents per share increase.
so that's .13 cents per share possible value for a $10.00 rise, give or take.

what have I got wrong ?
