Matt Manson, president and CEO, commented:

We are pleased that in our first year of production at the Renard Mine we are reporting carats, tonnes and grade results broadly in line with guidance. This is a strong testament to the dedication of our operating team and the quality of our Mineral Resource estimates. We continue to see a lower price environment for our diamond sales, in part due to what has been a challenging rough diamond market for a new producer, and in part due to the lower than expected quality and size attributes of our initial production as we process its recovery.
For the Stornoway team, 2018 will be a year of process improvement in diamond recovery, as well as focus on the initiation and ramp-up of our underground mine. It will also be a year with renewed focus on the future at Renard, with opportunities evident to us in processing expansion, resource conversion, and new exploration. Most importantly, we will seek to continue the excellent EH&S performance that we achieved in 2017, with no lost time injuries amongst Stornoway personnel or environmental derogations against permits recorded during the course of the year
