Patience is key. All, I feel the frustration with this stock as well, but we all need to be patient here, especially for penny stocks. They don't follow general market rules, and everything can get the SP skyrocket or collapse.
What you need to evaluate is the real value of the company. If you own this stock, it means you do believe in it, and the ressources under ground. We've seen a significant rally from the recent 23 cents decline, and good news are coming along the way with the drill results, we all know that. SP will move higher over time, but we need to be patient. Zinc price is not going anywhere, nor as all the ressources under ground.
Last, if you think this stock is frustrating, I invite you to look at NYX, completely different business, story, and SP, but you'll quickly realize that SP does not always follow logic rules. And often, when they don't, people take advantage of it. In NYX case, that was a 110% takeover premium.
Be patient.
