The public comment period related to the draft environmental impact statement for the Ambler Mining District Industrial Access road the project will need is due to close tomorrow (October 29) following which the Bureau of Land Management is due to complete the EIS process by year end or early 2020, following which Trilogy can commence permitting.
In what promises to be a busy start to 2020, Trilogy hopes to receive "a record of decision from the BLM and a permit in January, as it works to complete a feasibility study in the first quarter and will potentially see investment partner South32 exercise its option on the project at the end of January," a company official told Mining Journal. South32 owns 11.8% of Trilogy and has spent $30 million over three years on the project. If it exercises its option, it will need to spend $150 million to acquire a 50% interest.
