ANCHORAGE, Alaska -

Just over a month has passed since the Pebble Partnership lost its largest investor, Anglo-American.

Now a few organizations have joined up to try and add another hurdle to make sure the proposed mining project never takes off.

Leaders of three organizations have formed Bristol Bay United and will soon release a national television advertising campaign.

BBU wrote that it will "demand action from the Obama Administration and elected officials to stop the Pebble Mine and protect Alaska's jobs and way of life." 

The coalition is formed by Trout Unlimited, Bristol Bay Native Corporation and  the Bristol Bay Regional Seafood Development Association.

Jason Metrokin, CEO of BBNC, was not available to comment. Repeated calls to the other organizations by Channel 2 were not returned.

The campaign, however, will hit Alaska airwaves starting Thursday. 

Pebble Partnership spokesperson Mike Heatwole said the pro-mine group has not decided what the future holds for its ad campaign strategy.

"We haven't made any full determinations as to what we're going to do as a result of the recent withdrawal from Anglo-American," Heatwole said. "We have been evaluating all of our programs an projects and setting our objectives going forward."

The Pebble Partnership previously announced it was laying off an undisclosed number of workers.
