With an abrupt doubling of the share price since late November, Northern Dynasty Minerals (AMEX: NAK) has been on an absolute tear lately. Because it's a stock I've owned for several years, I may be in a position to offer some timely, Foolish context.

Northern Dynasty and Anglo American (OTC BB: AAUKY.PK) are equal (50%) equity partners in the monumental Pebble copper-gold-molybdenum project in southwestern Alaska. As the owners of other world-class ore deposits in North America can attest, the equity markets have a tendency to maintain heavily muted asset valuations on large-scale development projects until considerable visibility regarding mine planning, financing, and construction has been unveiled.

When the entire gold sector plummeted to ludicrous stock valuations during the financial crisis of 2008, for example, I noted that Seabridge Gold's (NYSE: SA) stock equated to $10 per measured and indicated ounce of gold in the ground at the company's KSM project in British Columbia. Those shares have tacked on 220% since that time; aided by rising gold and copper prices, a subsequent 40% resource expansion, and ongoing exploration success.

On the other hand, one could argue the market is well advised to keep valuations low on these high-stakes plays, where project financing, engineering, and permitting can each present daunting challenges. On a smaller scale, Taseko Mines (AMEX: TGB) shareholders were reminded of the risks involved with development-stage projects when the Prosperity project was denied its permit by Canadian federal authorities.

Because initial opposition to Northern Dynasty's Pebble project by environmentalists and the nearby salmon fishery was particularly vocal and intense, I believe the market has gone the extra mile to discount the permitting hurdle faced by the Pebble Partnership in their quest to construct this mine. Over time, however, as the timetable for selection of a specific mine plan and release of a prefeasibility study draws the project ever closer to the all-important permitting process, the stock may well attract buyers betting on eventual project approval.

The reality is that Pebble's 55 billion pounds of copper, 66.9 million ounces of gold, and 3.3 billion pounds of molybdenum (measured and indicated) are likely too vast a treasure to remain underground. The deposit is roughly comparable in scale to Ivanhoe Mines' (NYSE: IVN) celebrated Oyu Tolgoi project in Mongolia.

Along with the nearby Donlin Creek project -- which is owned jointly by NovaGold Resources (AMEX: NG) and Barrick Gold (NYSE: ABX) -- Northern Dynasty has expressed interest in a natural gas pipeline to significantly enhance the project's life-of-mine cost metrics. In addition to the mounting visibility for long-term copper demand from the likes of China and India, I believe these pipeline discussions may be sparking resuscitated interest in Northern Dynasty and the profit potential of its Pebble project.
