With gold and silver prices testing new highs, we turn to several leading resource experts -- Mary Anne and Pamela Aden, Mark Skousen and Larry Edelson -- for their favorite plays in the sector.

In The Aden Forecast, the Aden sisters explain, "Gold and silver recently moved well into record high territory, and it looks like they are poised to head even higher.

"Most impressive, gold's leading indicator still has room to rise further before it reaches the high area. This tells us that gold's current C rise is very strong and it's now likely headed to our next target level near $1200. Meanwhile, December gold will remain super strong above $1,020.

"Silver may become the next commodity China runs up in price, just as it's done with oil, copper and uranium," exp,ains Peter Krauthis.

Here, the 20-year gold market veteran -- and newest member of The Money Map Reporter team -- looks at the outlook for silver, and the best way to invest in the metal: iShares Silver Trust (NYSE: SLV).

"After 50 years of forbidding precious metals ownership, China's government is now taking the opposite path -- encouraging its citizens to invest in silver. Chinese investors can now buy silver bullion in 500 gram, 1, 2, and 5 kilo bars.

"I want to profit from a weak dollar," says Jack Adamo. In Insider Plus newsletter, he adds, "We will do it by adding two newly-launched ETFs -- one for silver, one for gold."

"The huge creation of money in the last year must go somewhere. The Fed is creating yet another bubble to offset the deflation in demand.

"Meanwhile, the U.S. dollar has weakened in almost exact proportion to the rise in stock and commodity prices. By keeping interest rates near zero, Central Bankers force investors to participate in the asset inflation unless they're willing to accept zero return on their money.

"Gold and silver have taken the limelight," says Mary Anne and Pamela Aden, adding "Gold looks ready for take off and silver is poised to outperform gold."

In addition, Doug Fabian is a fan of silver. In Making Money, he suggests, "When inflation threatens, silver offers a safe haven; even when inflation worries subside, silver still retains appeal due to its many uses."

We begin with the Adens; in their The Aden Forecast, they explain, "Technically, gold's 'C rise' is off and running and the triangle it's formed has clearly broken to the upside, with gold recently closing at a three month high today.

Mary Anne and Pamela Aden are among the advisory world's top authorities on metals and resources.

In a recent Q&A session, the editors of The Aden Forecast answer the most common questions that they are asked by readers as to the current state and future outlook for the precious metals markets.

In addition, the sisters answer what they say is the most frequent question they receive: "What is the best way to buy gold." Here, they offer a review of five strategies for investing in gold, including their top picks among stocks, closed-end funds and ETFs.

"Keep your gold for the long-term; it's today's best investment," says Mary Anne and Pamela Aden in The Aden Forecast. "Despite normal ups and downs, we strongly believe you'll be glad that you held hold onto your gold."

"Gold, silver and most of the gold shares are about the only markets to show gains so far this year. Everything else is down, and in many cases down sharply. Gold has recently been hitting new, or multi-year highs against the euro, the Dow Industrials, bonds and oil.

"In other words, it's stronger than these other markets. Gold is outperforming them and the percentage gains are greater in gold compared to all of the other markets.

"Simply put, gold is where you want to be. Silver is good too. These are the best markets. That's why we've consistently stressed keeping a large part of your investments in gold, silver and their shares.

"Will there be a recession or not?" asks Mary Anne and Pamela Aden. In The Aden Forecast they note, "The scales are now tipping to inflation," which they view as bullish for gold and silver.

"Sure, the economy will probably slow down in the months ahead and stagflation is also a likelihood. That is, slower economic growth combined with inflation.

"The Fed and the world's largest central banks are working together in a massive, historical concerted intervention to provide all the money and liquidity that's globally needed to keep things rolling along. Money supply, for instance, is soaring at a 16% growth rate, the most in 47 years.

"The latest producer price figure strongly supported our view since it was the highest in 34 years, showing inflation running at a 38% annualized rate. Since producer prices lead consumer prices, this is a huge red flag that big inflation is coming.

"The new record high in the gold price is telling us the same thing, and so are the record highs in oil and the commodity markets. In other words, if a serious recession were coming, gold and commodities would not be soaring.

"Gold is an inflation barometer and the action in this market alone is signaling that inflation will very likely dominate the economic scene in 2008. Inflation is bad for bond prices. It usually means higher interest rates and this time is not an exception.

Each year Steven Halpern, editor of TheStockAdvisors.com, surveys the leading financial newsletter advisors asking for their favorite stocks for the coming year. This article is part of his 24th annual Top Picks Report.

Resources expert Mary Anne Aden, turns to silver for both her favorites for 2007 -- selecting the exchange-traded fund iShares Silver Trust (ASE: SLV) as her conservative investment and Silver Standard Resources (NASDAQ: SSRI) as her top speculation.

In The Aden Forecast she explains, "In recent years, commodities have been rising strongly and this boom is expected to continue in the years ahead. Why? China and other emerging nations have been buying on a grand scale, and it's not only commodities.

"As these countries build and grow, demand has increased sharply for oil, other raw materials, and metals. The strongest commodity has been silver. It's consistently outperformed nearly every other investment, and with reason. More silver is being used than is being produced and it's headed for a world shortage.

"That makes silver a top pick for 2007, and an easy way to profit is to buy the silver ETF, iShares Silver Trust. The best silver share is Silver Standard Resources. Although higher risk than an ETF, this stock is a good way to benefit from silver's potential, and is my top speculative pick for the coming year."
