Wengfu, this is no surprice. The company has been spending about 40M per year. At the same time the value of their assets underground has more than doubled over the last two years. They also have no debt so they have the opportunity to leverage up. They also have not been issuing new stock.

I am interested in your concern about the company. But please give some more details....Why? Just please no generics, criticize the numbers, be specific, give examples, precedents.
