"When building a portfolio of junior mining stocks, stick with the best -- not just the cheapest," says money manager and advisor Adrian Day in his industry-leading The Global Analyst.

Although he is cautious on gold prices for the near term, Adrian Day suggests, "Gold is still only part way through its current bull move, one that likely still has years to run." Here, he looks at five favorite top-quality junior miners.

"Gold has had an extraordinary run, based partly on the decline in the dollar, which appears overdone in the short term. The fundamentals for a weaker dollar and for a stronger gold price remain intact, but I would be cautious about chasing markets now, especially the seniors.

"But it would be a mistake to sell too much, particularly in an attempt to trade the market and buy back precisely the same stocks at lower prices. Such attempts often end badly, as one fails to buy back favorite companies after selling at perhaps intermediate tops.

Last December, over 100 stocks were featured in our Top Picks for 2007 report. Now, at mid-year, we turn to the 20 advisors whose picks showed the strongest gains to get an update on their previous picks, as well as a new favorite stock for the second half of the year.

Adrian Day, editor of the Global Analyst, chose Virginia Mines Inc. (TSE: VGQ) as his favorite stock for 2007, which rose 31% as of 6/1/07. Here's Adrian's original recommendation on Virginia Mines and his current opinion on the stock.

His new favorite for the rest of 2007 is -- like Virginia -- a "gold company with a difference." His new pick is Vista Gold Corp. (ASE: VGZ). He explains, "During the early 2000s, when the price of gold was weak, Vista acquired known gold resources, but ones that were uneconomic at the time.

"This enabled it to build reserves inexpensively, and rather than mining them when the price was low, it held on to the gold in the ground, building value as the price of bullion appreciated.

"Now Vista has 12 properties around the world in various stages of development, some economic at today's higher price. Together, it has over 13 million ounces of resource (proven, probable, and indicated), valued at just over $20 per ounce in the ground -- very cheap.

"In addition to the considerable exploration potential at many of its properties, it also has $20 million in cash. With strong leverage to rising gold prices, we would buy Vista as an option on gold, but one without an expiration date."

Canada-based Virginia Mines Inc. (TSX: VGQ) is the favorite speculative play for 2007 from resource expert Adrian Day. The editor of The Global Analyst, he says, "Gold and other precious metals have resumed their bull market. The best returns often come from junior companies, particularly companies that make a discovery. But in exploration, the odds are heavily against you. We have found a company, however, that combines the potential of the typical exploration company without the usual risk.

"Virginia Mines, the largest landowner in the Canadian province of Quebec, typically stakes prospective ground and undertakes initial exploration before bringing in partners, who typically spend all of the exploration dollars in return for a stake in any discovery.

"Though Virginia reduces its share of any one success, it increases greatly its odds of being successful. It is like have parts of multiple, non-expiring lottery tickets instead of simply one ticket in one drawing. Virginia has about a dozen active projects, including drill programs on at least four different properties over the next few months. It has top-quality management and a super strong balance sheet of C$45 million.

"Virginia may or may not succeed this coming year, but in the worst-case scenario, with no new success, the company will still be around, in a strong position, to fight another day. That's why Virginia is our favorite exploration company, and one we are comfortable owning for the long term."
