If you only have $5k, I would say look for an explorer which has; - substancial cash in bank. - a cornerstone investor. - multiple projects in different resources. - high grades and large JORC resources. - potential to expand asset bases through further acquisitions. - and most importantly, great management.
Then I would say park your money there. Watch and get to know the trading ranges of the stock to increase your holding. Studying technicals online will also increase knowledge and help with any trading of other stocks along the way (but paper trade for 6months+ at first). In a few years you should be very well rewarded. Although nothing is certain in the markets.
