2017-02-11· The results come back and the guy says, meaning there is gold in this area,: "Eighth of an ounce per ton." Then they just cheer and hug each other, they scream "We found a gold mine!" Now I understand what he means.
4.5 million total tons carbon / 5.5 million oz gold = .82 tons of carbon for each oz of gold. Newmont is emitting 1/3 of a ton of carbon for each ounce of gold produced from diesel consumption and 0.82 ton of carbon for all direct energy consumption per ounce of gold.
While most companies post mining results in metric units like meters and grams, metals are almost universally traded and valued in imperial units: Precious metals are generally valued in troy ounces, while industrial and base metals may be traded in lbs or short tons.
Most of this was mined at gold prices of US$20 to US$35 per ounce above cut-off grades of 17.1 grams per ton (0.5 ounces per ton) up to and including 1935 and 13.7 gpt (0.4 opt) thereafter. Consequently, most of the resources along the Atlanta Shear Zone were not mined and remain in site.
An overall average grade of 10.2 grams per tonne gold was returned from 1,555 muck samples collected from during mining that bulk sample. Using a 4.0 grams per tonne gold cut-off, the bulk sample estimate includes 46 per cent more tonnes, 8 per cent higher gold grade and an estimated 56 per cent more ounces of gold than predicted from the geological model that forms the company's mine …
1) The hole was 169 meters or 554 feet of 2.12 grams per tonne or 0.062 ounces per ton of gold. 2) Clifton Star told me that the true width was approximately 80%, and so I used 80% of 554 feet or 444 feet as the edge dimension of my box.

Where, at the turn of the 19th century, mining was only profitable at above 15 grams of gold per tonne, mines could now operate profitably on grades of as low as one gram per tonne. Mines like the Super Pit at Kalgoorlie now incorporate many former surface and underground operations in one large open pit.
Toi gold mine - Wikipedia, the free encyclopedia The Toi gold mine (Japanese:, also ) was an important ... One ton of rock would produce in average 5 to 10 grams of gold, although 30 grams ore was common, and some rock has yielded as much as 600 g of gold per ton.

Though during the CA gold rush having 1-3 oz per ton was super good back then though. My chemical extraction process is good for me, getting it to market is where the problem lies. I`ll be incorporating ...
During the period of 1904 to 1955, the Nickel Plate deposit was mined as an underground mine, with gold grades ranging from 11.70 to 13.97 grams per tonne (0.376 to 0.449 ounces per ton). Some intermittent exploration by outside groups took place after the 1955 closure.

Conversely, when a mining company reports a drill result of 10 grams per tonne, you now know that this equals (10 x 0.029 =) 0.29 ounces per tonne. On the break even analysis page, I also explained how you can convert a drill result reported in a percentage (%) to an amount in pounds (lbs) per tonne.
The quartz veins run 20 cm to 1.5 meters wide (rosary bead layout) with gold content that varies from 8 grams to 40 grams per ton. The ore averages around 10 grams/ton. Some of our mines have multiple parallel veins that allow easy side entry from current mining development.
