"You need to be prepared for the possibility of a correction in gold," says resource specialist Curtis Hesler, who adds, "Looking at the long term, however, gold will probably double from current levels."

The editor of The Professional Timing Service explains, "As such, the key is to buy fear and sell comfort. Here we look at a trio of favorite closed-end funds invested in the metals sector.

"Gabelli Global Gold and Nautral Resources & Income (GGN) s a closed-end fund investing in a variety of tangible asset plays.

Some 90% of their holdings are in equities, which are balanced about 32% in energy and 58% in metals and mining. They also hold convertible bonds in these two sectors.

"It's time to buy Gabelli Global Gold, Natural Resources & Income Trust (NYSE: GGN) a closed-end management investment company that seeks to provide a high level of current income," says Bryan Perry.

The growth and income expert -- and editor of The 25% Cash Machine -- highlights the high-yielding play on gold and natural resources.

"Back in December we sold our position in GGN for a 45% gain in two months. But at that time, I promised to jump back on board after a sharp pullback, since gold is going to be a good inflation hedge this year and could hit $1,000 per troy ounce. Well, now it is time to buy back into GGN.

Curtis Hesler, editor of The Professional Timing Service, believes that the recently announced Chinese investment fund will have a significant impact on commodities. The fund, he explains, was developed in order for China to diversify its reserves.

He notes, "The great Chinese reserve fund has now been established, and it is a whopper; they have announced that they will hold $650 billion of their reserves at ready.

Further, he adds, "They will also invest $200 billion to $250 billion a year that they expect to receive hereafter. That is a lot of money!"

So, what will they buy? According to Hesler, "They will certainly spend a lion's share on raw materials and other commodities."

The advisor forecasts, "This money will likely be the engine that will fuel the next major leg in the commodity bull market. China has every intention of being a significant player on the global scene; and to do that, they will need to increase their gold reserves."

Already bullish on gold, the development of the China investment fund for its reserves is an added demand factor supporting his optimistic stance. He notes that some resource experts are estimating that China will need to accumulate 2,000 to 3,000 tons of gold toward this goal.

Among junior gold mining stocks, Hesler owns Gammon Lake (ASE: GRS) and Yamana (NYSE: AUY). Another "solid core metal investment" he adds is Gabelli Global Natural Resources (ASE: GGN), which he points out has a decent dividend and as a closed-end fund, offers a broad-based investment in metals.

As a long-term investor, Hesler argues for patience and suggests that investors should accumulate positions during periods of price weakness. Long-term, however, he says, "I firmly expect to see gold eventually hit $1,600. That will put the mining stocks through the roof."
