The silver contract for May delivery gained $1.61, or 4.8 percent, to $35.10 a troy ounce.

A weaker dollar was the major catalyst for gold and silver specifically, and commodities in general on Wednesday.

Benchmark West Texas Intermediate crude for June delivery was up $3.19, or 3.3 percent, to settle at $100.10 a barrel on the New York Mercantile Exchange.

Brent crude rose $2.31 in London, or 2.1 percent, to settle at $112.30 a barrel on the ICE Futures exchange.

The U.S. dollar index, which measures the dollar against a basket of six currencies, traded at 75.438, down a little from 75.441 late Tuesday. That was also a factor in gold and silver prices going up.

The U.S. dollar index was up 0.74 percent to $75.75 as the euro continued to get hammered on the sovereign debt crises in Europe. The euro plunged 1.7 percent last week as Greece was again in the spotlight for the need to probably be bailed out again, as it appears the country refuses to implement austerity measures to deal with the situation, as it, along with numerous countries, has made progressive, socialists promises they aren't able to keep.

Besides the long-term collapse of the U.S. dollar and the European sovereign debt crises, other factors offering support to gold include tightening in China, inflation, and unrest in the middle east.

Goldcorp (GG) closed Friday at $47.76, gaining $0.06, or 0.13 percent.

Miners (NG) (SA) (TRE) (GRS) (KGC) Mixed as Gold Closes Up

Gold was able to shake itself of silver Friday, as it has been weighed down by the plummeting price of silver in recent trade, which also has been dragging down gold miners NovaGold Resources Inc. (AMEX:NG), Seabridge Gold (Amex:SA), Tanzanian Royalty Exploration (AMEX:TRE), Gammon Gold (NYSE:GRS) and Kinross Gold Corp (NYSE:KGC).

Ivanhoe Mines Ltd. (NYSE:IVN), Royal Gold (Nasdaq:RGLD), Northgate Minerals (AMEX:NXG), Tanzanian Royalty Exploration (AMEX:TRE) and Newcrest Mining (OTC:NCMGY.PK) got hammered Thursday as gold and silver prices continue to plunge.

The silver contract for May delivery closed 8 percent lower, down $3.152, at $36.231 per troy ounce.

Since the Friday settlement price silver has plummeted 25 percent.

The U.S. dollar was also up, adding pressure to the two precious metals, as it gained 2 percent against the euro. That came largely from European Central Bank President Jean-Claude Trichet who suggested there will no interest-rate boost in the near future.

Nothing has changed the underlying fundamentals for gold or silver though, and this is just a healthy correction before gold and silver prices begin moving up again.

As long as easy money policies continue by the Federal Reserve and interest rates remain near zero, there is nothing to stop gold and silver prices from continuing to rise.

Inflation, political unrest, sovereign debt crisis and the collapsing U.S. dollar will also play a major role over time for gold and silver prices.

Ivanhoe Mines Ltd. (NYSE:IVN) closed Thursday at $23.93, falling $1.03, or 4.13 percent.

Miners (ANV) (SA) (UXG) (TRE) (NCMGY) Trade Mixed as Gold Closes Down

The U.S. dollar index lost 0.15 percent to $73.01, dropping from Tuesday's 73.127 close. The dollar index is down 7.5 percent so far in 2011.

Against the euro, the dollar plunged to its lowest level Wednesday since December 2009.

Other than the fall of the dollar, other factors that would have normally supported gold was the underreported decision by the European Union to bail out Portugal for close to 78 billion euros.

Also largely ignored was the ADP Employment Change report for April, which showed the private sector missed the anticipated addition of 200,000 jobs, being able to only generate 179,000 for the month.

Also of note Wednesday was the Institute for Supply Management’s services-sector index, which was weakened more than expected in April, confirming that American growth is slowing.

US Gold (UXG) closed Wednesday at $8.09, gaining $0.02, or 0.25 percent.

Correction for (TRE) (SA) (GOLD) (AU) as Gold Prices Fall

Shares of gold miners like Randgold (NASDAQ:GOLD), AngloGold Ashanti (NYSE:AU), Tanzanian Royalty Exploration (AMEX:TRE) and Seabridge Gold (Amex:SA) were suffering Tuesday as the price of gold dropped on the session, as the U.S. dollar gained a little.

A temporarily stronger U.S. dollar put some pressure on gold and silver prices Tuesday, as the U.S. dollar index climbed 0.04 percent to $73.09.

Also surprising the market was the decision by India to boost their interest rates by 50 basis points to fight inflation. That puts the lending rate their at 8.89 percent, and the overnight lending rate at 7.25 percent.

Silver fell another $3.49 Tuesday to settle at $42.576 per troy ounce on the Comex division of the Nymex.

Most of pressure on silver prices has come from the CME Group decision to raise margin requirements by 11.6 percent, starting at the close of market on Tuesday.

Gold looks like it's just taking a needed breather before resuming its upward run.

Gold stocks have been overall lagging the price of gold, and that should change assuming the costs of inputs remain lower than the push up in gold prices.

A growing number of gold miners are increasing dividends to attract investors.

AngloGold Ashanti (AU) closed at $48.18, falling $2.21, or 4.39 percent.

It is surprising to see gold and silver be pressured, as in April gold was up 8.92 percent and silver a whopping 28.72 percent.

One piece of financial information somewhat ignored Monday because of the hoopla surrounding the death of Osama bin Laden, was the manufacturing report concerning China in April which showed production had slowed down during the month. That should help the price of gold and silver going forward.

Ivanhoe Mines closed at $26.16, falling $0.12, or 0.46 percent.

Barrick (ABX) (IVN) (NG) (NEM) (TRE) Trade Mixed as Gold Price Breaks Records Again

The ICE Futures U.S. Dollar Index was down 0.2 percent on Friday, increasing demand for the dollar-denominated precious metals by making them less expensive for foreign buyers.

Inflation concerns in America, Europe, China and Russia also has contributed to the jump in gold prices.

Other factors affecting gold and silver are the collapsing U.S. dollar, sovereign debt crisis in Europe, unrest in the Middle East and consequences of the Japanese earthquake.

Northgate Minerals (AMEX:NXG), Aurizon Mines (AMEX:AZK), Tanzanian Royalty Exploration (AMEX:TRE) and Gammon Gold (NYSE:GRS) closed mixed Thursday even as gold and silver prices broke all-time records. It appears investors are taking some profits off the top.

On the other hand, silver futures plunged Tuesday as investors took profits from record prices as uncertainty over the Federal Reserve policy decision coming up could have an adverse effect on the metals' unprecedented rally.

Gold Breaks $1,500 as NovaGold (NG) (EGO) (AZK) (TRE) Close Mixed

After blowing past the $1,500 an ounce mark on Tuesday, gold prices settled just under the important psychological barrier at $1,495.10, as gold miners NovaGold Resources Inc. (AMEX:NG), Eldorado Gold Corporation (NYSE:EGO), Aurizon Mines (AMEX:AZK) and Tanzanian Royalty Exploration (AMEX:TRE) closed mixed on the day.

Gold prices settled just below $1,500 an ounce after hitting that level earlier Tuesday's session, helped by a weaker dollar.

The gold contract for June delivery rose $2.20 to settle at $1,495.10 an ounce, shy of its all-time and daily high of $1,500.50 an ounce. Spot gold prices dropped 50 cents, to close at $1,495.90 an ounce.

Silver prices for May delivery climbed almost a dollar to settle at $43.91.

Most of this is based upon the collapsing U.S. dollar, which pulled back again today, the tightening in China, sovereign debt crisis in Europe, unrest in the Middle East, inflation concerns and consequences of the Japanese earthquake.

Add to that the warning from rating agency S&P that the U.S. could have its debt downgraded if it doesn't deal with the growing debt crisis and you have a weak macroeconomic outlook favoring gold and other commodities.

NovaGold Resources Inc. closed Tuesday at $13.18, gaining $0.07, or 0.53 percent. Eldorado Gold Corporation ended the session at $17.97, up $0.21, or 1.18 percent.

US Gold (UXG) (AZK) (TRE) (AEM) Close Mixed Even as Gold Prices Soar to Record High Again

While gold prices reached new all-time highs on Monday, that wasn't the direction for most gold companies, such as Aurizon Mines (AMEX:AZK), US Gold (AMEX:UXG), Agnico-Eagle (NYSE:AEM) and Tanzanian Royalty Exploration (AMEX:TRE), which closed mixed on the day.

Spot gold jumped as high as $1,497.20 an ounce Monday after Standard & Poor’s downgraded its credit outlook for the United States, revealing the risks associated with its own sovereign debt crisis.

U.S. gold futures for June delivery settled up $6.90 an ounce at $1,492.90.

The sovereign debt crisis in Europe continues to boost gold as well, as the euro and U.S. dollar continue to face pressures on out-of-control government spending and refusal to make meaningful spending cuts.

Global inflation and unrest in the Middle East also continue to be major factors in the gold price equation.

As to why most gold miners have been pulling back, a lot of that is based on the fact the majority of the miners are based in Canada, and so the weaker U.S. dollar as it relates to the Canadian dollar is a major factor a lot of investors in gold companies don't take into account.

Agnico-Eagle closed Monday at $63.60, dropping $1.64, or 2.51 percent. US Gold closed at $9.15, falling $0.26, or 2.76 percent. Tanzanian Royalty Exploration ended the day at $6.34, gaining $0.02, or 0.32 percent. Aurizon Mines closed at $6.70, losing $0.08, or 1.18 percent.

Spot gold was up 1.4 percent to $1,474.30 an ounce, closing in on its record $1,476.21 set on Monday.

The collapsing U.S. dollar, tightening in China, sovereign debt crisis in Europe, unrest in the Middle East, increasing inflation and consequences of the Japanese earthquake are just some of the negative catalysts affecting the price movements.

The U.S. dollar was close to session lows, resulting in a further impetus to gold. The U.S. currency traded as low as 74.617, its lowest level since December 2009.

In base metals trading, May copper dropped 1.05 cents to settle at $4.284 a pound, July platinum increased $18.40 to $1,795.60 an ounce and June palladium was up $8.95 to $774.25 an ounce. May copper fell 1.05 cents to settle at $4.284 a pound

On Wednesday gold prices closed at $1455.60 an ounce. The Silver price for the May contract was higher by .43 percent at 40.24 an ounce.

The collapsing U.S. dollar continues to be a big factor, although it gained in strength near the end of trading Wednesday. Other factors are tightening in China, sovereign debt crisis in Europe, unrest in the Middle East, deepening food and fuel inflation and the consequences of the Japanese earthquake in the auto and tech sectors, among others.
