What is g/t in gold?

Grams per tonne of milled ore, or g/t, is the most common metric used to represent the grade of ore. The value of a precious metals mine is determined by its total estimated weight, the grade of the ore, and how difficult it is to extract and distribute.

What is a good g/t for gold?

Gold drilling results are reported in grams per tonne (g/t), and anything over 2 grams gold/tonne is deemed to be good.

What is the highest gold grade?

Technically speaking, the highest grade of gold would be nuggets, which are some of the only naturally occurring deposits of gold. Even these tend not to be pure 24 carat gold, but are certainly the highest grade of gold found naturally.

What does GT au mean?

grams of gold per tonne
g/t Au means grams of gold per tonne.

What does ppm mean in gold?

Gold is often found in ores composed of rock with very small particles. When it comes to mining, ore with grades of gold as little as 0.5 parts per million (ppm) can be economically mined. Because ore grades of 30 ppm are usually needed before gold is visible to the naked eye, gold in most mines is invisible.

What is a good copper drill result?

COPPER: Anything over 100 metres and 1\% copper equivalent or better is considered to be high-grade. For example, Serengeti Resources announced 119.6 metres of 0.9\% copper equivalent (copper plus gold values added together) at depths from 180 to 300 metres.

How much gold is in a ton of gold ore?

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 ounce. That would make the gold in a one pound ore sample worth approximately 75 cents, and this is assuming that the ore is extremely rich.

Where is the highest concentration of gold on Earth?

South Africa
World’s Largest Deposits of Gold The massive deposits of the Witwatersrand mines in South Africa have produced more than 40 percent of the world’s total production of gold.
