During the 1850s, gold and silver were extracted in the valley.

Gold is heavier than silver.

Where's the catch?

Gold is much more expensive than silver.

Wisdom is better than gold or silver.

Freedom weighs more than silver and gold.

From everything we've heard, from all sides, mining of minerals such as gold and silver, sand and alloys is a huge issue in Guatemala.

It's not even mining.

The city however gave the majority of its mining profit share over in favor of central Vienna government, which soon slowed the development of the city when the silver mining was at its peak at the end of the 18th century.

The larger the amount of silver, the larger the amount of corruption.

In the 2nd millennium, ore mining developed in Central Kazakhstan.

It looks like we have no clean silverware.

Silver chloride is not completely water soluble.

The country has significant reserves of natural gas.

The man is the hunter, and the woman is his prey.

Once gold was less valuable than silver in Japan.

The exploitation of mineral resources in the southern region

The prey dies once, while the hunter dies every day.

Abraham listened to Ephron. Abraham weighed to Ephron the silver which he had named in the audience of the children of Heth, four hundred shekels of silver, according to the current merchants' standard.

I don't want your gold or your silver.

He increased the silver purity of the denarius from 90 to 98 the actual silver weight increasing from 2.87 grams to 3.26 grams.

As expressed by Carol Corrales in a post for Rainforest Radio

Gas extraction in Tanzania, as seen by cartoonist by Masoud Kipanya.

Last year's output of coal fell short of the standard.

It had a weight of 29.44 g and a fineness of 873.0.

Oil output is coming back on line in meaningful quantities.

During the 16th century, Spain held the equivalent of US 1.5 trillion (1990 terms) in gold and silver from New Spain.

Some calm has returned, and oil production is resuming.

Petroleum, petrochemicals and natural gas continue to be the backbone of the economy.

Similarly, Spain ran persistent deficits in the sixteenth and seventeenth centuries, paid for by Andean silver.

In the late 1800 s, oil extraction involved dredging with a mule.

And, in many places, oil supplies are declining as old oil fields are depleted.

In the Caribbean, more than 60 of coral reefs are threatened by sediment, pollution, and over fishing.

Rome responded by reducing the gold silver content (the ancient equivalent of monetization), which led to sustained inflation in the empire.

Following the discovery of gold and silver in 1859 on the nearby Comstock Lode, Carson City's population began to rise.

If this oil is exploited, the pollution risks will be far higher than anywhere else.

Some petroleum experts argue that world oil production will peak in a decade or so.

Nickel mining is also important in the province, but is mostly concentrated in Morowali, on the opposite coast of Sulawesi.

My lord, listen to me. What is a piece of land worth four hundred shekels of silver between me and you? Therefore bury your dead.

Sterling silver is an alloy of silver containing 92.5 by mass of silver and 7.5 by mass of other metals, usually copper.

The 2½ and 5 escudos were minted until 1951, with the 10 escudos minted until 1955 with a reduced silver content.

Indeed, after two decades of cheap, abundant energy and exports of surplus output, a new cycle of expensive, scarce, and imported energy has begun, as oil production has fallen by one third since 1998, and gas production by 15 since 2004.
