If you're holding junior exploration stocks here in this market, you know exactly what I'm about to tell you. The explorers and many developers are now retesting, and some are breaking to new lows following the sharp rally in the producers in August & September.

Is this a second chance to dump mining shares and forget we ever discovered the sector? Not according to the actions of two chairman and a billionaire, all of whom are invested in two of my favorite mining companies.

One chairman increased his preexisting position in the company he is leading by over $1.3 million, another chairman just invested another $100k in the company he runs, and a billionaire backing one of these companies just added another $1.8 million to his preexisting position in the company.

What's the moral of the story here? The most successful insiders and resource investors are upping their positions here in this market by multiples of $100k. No position can be timed perfectly, but by adding during periods of extreme distress---like many companies are still in---we accumulate the types of investments which pay off many times over when the "dumb money" returns to the bottom half of the mining sector.

I'm also using this period to add to my positions, and I strongly encourage you to call your favorite mining companies, and ask what's going on. Maybe you'll discover some great news amid a market which really seems bleak.
