SRK Consulting of Denver, Colorado was retained to prepare a pit optimization report based on the block model prepared for the mineral resource estimate. A Whittle Shell pit was designed using the following parameters:

	Cost
Mining Cost ($/tonne mined)	US$ 1.84
Processing Cost ($/tonne of ore mined)	US$ 2.69
G&A Cost ($/tonne of ore mined)	US$ 1.61
Selling Cost ($/troy oz sold)	US$ 13.57
Royalty to Treasury Metals	3% of (Selling Price minus Selling Cost )
Overall slope angle (degrees)	50°
Gold Recovery (%)	60%
Gold Price ($/oz)	US$1,500

Based on the Whittle Shell defined incorporating the above criteria, measured and indicated resources of 33,000 ounces of gold and inferred resources of 1,300 ounces of gold lie within the Whittle Shell pits using a cut-off grade of 0.20 g/t Au.
