I would not borrow money from a credit card to invest in the stock market, and most definitely not in pennyland. Yes, KMAG is a rare company in the pinksheets and all the DD confirm that. I have been happy to put my hard earned money into KMAG and am confident long. But anything can happen in the wild west of stocks. Nothing is a sure thing, so going into debt to buy stocks (especially if you're new) is often bad news.
Borrowing to buy stocks also shows that you may not have the patience it takes to be an investor, and that you're hoping that you can make a ton of money so quickly that you'll pay off the credit card and be way in the plus side. This is dangerous thinking.
You have 100k shares. Be happy. Be patient. Financial health includes being debt free.
