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.

Several ounces of gold per tonne is considered to be high-grade for underground mining, although 5 grams gold/tonne is usually economically viable.

For every 2.5 grams per tonne (g/t) gold deposit, Mother Nature forms another 10 deposits around 1 g/t. Generally speaking, one gram per tonne works for open-pit mines, but underground gold mines require at least 2.5 g/t to be economic.

Gold Mine Development: 1 – 5 years It involves the planning and construction of the mine and associated infrastructure. Mining companies must obtain appropriate permits and licenses before they can begin construction. This will generally take several years, although this varies greatly depending on location.

Individuals, businesses, and governments continue to clamor for more gold. Gold reserves are finite, and pulling new gold out of the ground can be very expensive. In fact, it is common to hear industry insiders cite $1,200 as the all-in cost for mining a single ounce of gold.

Lighter Colored Rocks: If you notice out-of-place colors in a group of rock formations, it can be a gold indicator. Acidic mineral solutions in gold areas can bleach the rocks to a lighter color. Presence of Quartz: Quartz is a common indicator that gold MAY be nearby.

Many rich gold deposits have been found by sampling creeks for placer gold. Once gold is discovered, the prospector follows the source upstream until the gold stops, indicating that the source of gold is located there. Tracing gold to its source is the best way to find the lode sources of gold.

If your gold piece does not change colors and does not fizzle or react to the vinegar in any way, it is probably real. The acid in white vinegar breaks down many chemicals, but it won’t break down gold.
