The Financial Post reports in its Thursday edition that Deep Sea Minerals is removing a series of promotional materials from the Web after the British Columbia Securities Commission raised questions about their accuracy. The Post's Gabriel Friedman writes that Deep Sea said it was launching a review of "all investor relations materials" to ensure they contained "balanced disclosure." That review extends to its own corporate presentations and social media posts, as well as a series of posts it paid an outside company to create through a contract worth $400,000. The company said it "may have overstated its growth potential and the certainty of its trajectory, omitting underlying assumptions and risks." Some of the material Deep Sea is removing occurred in a corporate presentation published last month in which it compared itself with other companies that already hold mining concessions -- essentially licences to explore the seabed -- and to companies that hold patents for subsea mining technology. Deep Sea has now said it does not hold either. "Furthermore, if the company acquires mineral rights, achieving commercial operations, if ever achieved, will require significant time and capital expenditures," it said.
