GIR's Zinc Co. Spin Off

All the talk in GIR.ASX at this moment is about their Zinc Co's Spin Off. I did not really know what actually these people are talking about, but looking at the share price, it seems to be a good thing for shareholder. I bought GIR about a month ago for $0.69 per share. It went down to $0.61 before it bounched back to (now) $ 0.83. I should have bought more, but I think the train have left the station now.

Searched on the internet, I found out a few facts about spin off:

• A spin-off is an attractive option when a company and its stakeholders realize that one or more of its subsidiaries are more valuable as a separate entity than as part of the parent corporation. Spinning off a business rewards investors because it makes it easier for the markets to recognize the full value of a smaller entity eclipsed by larger organization. It can also help a parent company exit non-essential businesses and focus on its core competencies.
• In a "spin-off," a parent company distributes shares of a subsidiary on a pro rata basis to the parent company's shareholders. As a result, the subsidiary becomes a separate company. State law and the rules of the stock exchanges determine whether a company must seek shareholder approval for a spin-off.

Will wait and see, what is going to happen to Giralia's share, once the announcement is released. (Yes, it hasn't been released yet... )
