"Brown’s Range is expected to produce the equivalent 148.2 tonnes of Dysprosium in the first three years of operation in a total of 1,719 tonnes of rare earth oxide."

Northern intend to stockpile extracted ore for three years during the initial phase of construction, but as the primary pilot plant stage is essentially a fully producing mine running at 10% output, material awaiting processing will be piling up from the very beginning. This is a sensible approach and allows the development of the project to incorporate effective troubleshooting along the way. Larger operations will almost always throw up significant technical gripes that, without the proper time to resolve, can derail many moons of hard labour. Crucially, this period will wait out the slump in rare earth prices that is expected to lift over the next few years, with many stating that the price of Dysprosium will double by 2020."

148,200kgs*$250 = $37 Million or +- 12.3 Million during first year, at current prices.
