• The Mineral Resource Estimate has been constrained to a preliminary optimized pit shell, using the following parameters: SG = 2.57 gm/cc based on testwork, mining costs = $1.50/tonne,

mining recovery =98%, mining dilution = 2%, process cost = $3.25 per tonne, G&A = $0.55 per tonne, gold price = $1,300 per troy ounce, throughput at 15,000 tpd., discount rate

= 7%. Top cut at 32 gpt.

• Conforms to NI 43-101, Companion Policy 43-101CP, and the CIM Definition Standards for Mineral Resources and Mineral Reserves. Inferred Resources have been estimated from geological

evidence and limited sampling and must be treated with a lower level of confidence than Measured and Indicated Resources.

• All numbers are rounded. Overall numbers may not be exact due to rounding.
