Janet Mills has to be pragmatic. With the exception of the I95 corridor from Bangor south and immediate coastal area most of the Central, Northern and Eastern Maine is hurting. Although many optimistic things have been said of the future economic potential of the KWW national monument, the expected economic rush has not happened. Last thing I knew the Sherman Mills exit still consists of a Irving gas station on both sides of the highway and a motel court that gets wintertime snowmachine traffic. They were there before KWW. I havent heard of major economic revitalization in Patten. There was a high profile claim that the lack of signage on the highway was blamed by some to reduce traffic to KWW but really with a car nav in most cars and google maps on everything I doubt the lack of signage stops a lot of folks who want to visit from visiting. There was a initial demand for real estate along RT 11 and some movement on real estate in Millinocket but it I expect its mostly speculative. About the only land rush is by Menonites and possibly Amish families priced out of PA for the farmland along RT 11. The timber industry is not thriving, the tariffs on Canadian lumber help but it just keeps plants from closing. The big hope for Millinocket, a laminated structural lumber mill went away due to an IRS lien on the old mill site and headed down to Lincoln if it ever gets built (highly dependent on subsidies and changes in US policy to incentivize substantially increased building costs for structural wood buildings.)
Here comes a firm with a proposal to do a "clean" underground mine with a claim of far less environmental impact of an open put mine. The jobs and taxes associated with it are not seasonal tourist, these in theory are full time longer term jobs, in theory with benefits. Whether its true or not is for the experts to review. Nevertheless its a long term development that probably will not even be started by the end of the governors first term. That is a great place for a governor to be in it as it allows the promise of future prosperity to an area which has not seen much hope for years. The key is the large economically powerful southern counties are pretty clueless on what is going on north of Bangor, most would not even know where Patten is. If the project can stay off the radar of environmental groups its not a liability to the governor down south but a big plus up north. It could be an option is just buy off a few environmental groups like the powerline did.
Unlike the recent proposal farther north on Irving land, the claim is its not going to be open pit mine. I dont how they avoid acid mine drainage but the claim is they can and the claim is also that there will be no onsite upgrading of the ore which usually is most environmentally damaging aspect. Of course it has to happen somewhere but I expect there is some community somewhere that is desperate enough to get the short term benefits and not worry about the long term impact. Take a look on Google Earth of Fort McKay Alberta, Sudbury Ontario, or not that far away Asbestos Quebec.
