Nautilus Minerals
Nautilus Minerals bills itself as the first company to commercially explore the seafloor for massive sulfide systems, a potential source of high-grade copper, gold, zinc and silver. The company is developing a production system to commercially extract these metals using existing technologies adapted from the offshore oil and gas industry, and from the dredging and mining industries.
On April 10, Nautilus closed a $2-million private placement; more recently, on April 20, it delivered a $2-million financing notice for May. Last week, the company’s share price rose 8.7 percent to close at $0.25.
