The US company plans to operate Dominion as a standalone business, appointing a new chief executive based in Canada.
The project, called Misery Deep, will require an investment of $6 million in 2018, $69 million in 2019 and $19 million in 2020.
The company has repeatedly offered to engage with Washington Corp on "customary terms," according to Chairman Jim Gowans, but that has not happened.
Strategy is part of Dominion's goal of securing the best deal possible for all its shareholders.
Montana-based Washington Co is offering 36% above the closing price of the Canadian miner’s shares on Friday.
The target group was the the top diamond consumer in 2015, a year in which most commodities plummeted, hitting the mining industry very hard.
More than 500 unionized workers are expected to ratify the agreement in an upcoming vote scheduled for March.
Brendan Bell, who has also resigned to Dominion's board, has agreed to stay on as CEO until June 30 to ensure a smooth transition.
Global rough diamond production will reach its peak in only three years before entering into a supply deficit by 2020, two separate reports show.

Investors have publicly called on the company’s independent directors to deal with the “misguided policies and missed opportunities” that have hurt their investment.
The company hopes to begin mining from the Jay pit before Ekati's existing reserves run out in 2020, and so avoid laying off workers.
