For example, lets say that a mine was processing ore valued at 1 troy ounce of gold per ton. This would generally be considered a very high-grade ore, worth mining in most cases. Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let's assume that gold is valued at $1500 per ...
Base charge.—$3.70 per net dry ton of 2,000 pounds; provided the sum of payments for gold, silver, load, and copper does not exceed $26 per ton.

Copper mining has become an especially capital-intensive industry – the average capital intensity for a new copper mine in 2000 was between US$4,000-5,000 to build the capacity to produce a tonne of copper, in 2012 capital intensity was $10,000/t, on average, for new projects. Today, building a new copper mine can cost up to $44,000 …

Kitco use the last quote at 5:00 PM as the close of that given day. Change is always the difference between the current price and the price at 5:00pm. For example: Silver last traded at $17.00 at 5:00 PM on January 17. If it is January 17 at 6:30 PM and the price is $17.02, we will show a change of +0.02.
A new metric has since been developed by the World Gold Council to report the "all-in sustaining costs" of mining gold. These numbers report that the cost of extracting an ounce of gold is actually over $1,000 per ounce, well above the aforementioned numbers. And since gold is currently trading at just over $1,200 per …
