Notes
1. Estimated average price per carat of the Mineral Reserve in Renards 2, 3, 4 & 65 expressed in March 2016 terms.
2. Expressed in nominal terms, and excluding Renard Mine Road capital of $69.4 million. Initial Capital Cost in the January 2013 Optimization Study was estimated at $793 million based on $752 million of cost and contingency plus $41 million escalation allowance. In April
2014, prior to the commencement of construction, Initial Capital was estimated at $811 million based on $754 million of cost and contingency plus $57 million of escalation. The estimate of $775 million of Initial Capital in the March 2016 Updated Mine Plan includes all
costs, contingencies and escalation allowances and represents a reduction of $36 million on the April 2014 estimate.
3. Expressed in real terms.
4. Expressed in real terms. Assumes a 2.5% escalation in diamond prices between 2016 and 2017 and a US$ exchange rate of C$1.35
5. Net of all royalties, costs incurred under the Mecheshoo Agreement (IBA) and the effective revenue impairment associated with the Renard diamond streaming agreement. For further information see the Stornoway AIF dated March 30, 2016.
6. After tax.
Reserve and Resource categories are
compliant with the "CIM Definition
Standards on Mineral Resources and
Reserves". Mineral resources that are not
mineral reserves do not have
demonstrated economic viability. The
potential quantity and grade of any
Exploration Target (previously referred to
as a “Potential Mineral Deposit”) is
conceptual in nature, and it is uncertain if
further exploration will result in the
target being delineated as a mineral
resource.
