Of the 74 kimberlites discovered, two (CH-6 and CH-7) form the foundation for the Phase One Diamond Development Program at Chidliak, as announced in the Preliminary Economic Assessment (PEA) completed by JDS Energy & Mining (JDS) in July, 2016. Chidliak is 100% owned
JDS was retained by Peregrine to lead their PEA for Chidliak. JDS developed a conventional open pit mine plan and cost estimate, rationalizing capital and operating costs.

The total planned mine life is 10 years with a production rate of 1.2M carats per annum, peaking at 1.8M carats per annum with a LOM head grade of 1.67 carats per tonne. LOM pre-tax cash flow is C$1.3B with an operating margin of 72%. Pre-production capital includes the construction of a 160 km all-weather road to connect to Iqaluit.
