JDN - Silver Coin Project: Updated NI 43-101 Resource Estimate


Silver Coin Project - Updated NI 43-101 Resource Estimate (Minarco Mine-Consult, March 4, 2011)

At a .30 g/t Au cut-off grade:

Measured Resources:

4,372,225 t @ 1.55 g/t Au, 6.53 g/t Ag, .26 % Zn

= Au: 218,410 oz
= Ag: 918,417 oz
= Zn: 25,531,741 lb

Indicated Resources:

19,759,025 t @ .98 g/t Au, 5.57 g/t Ag, .15 % Zn

= Au: 624,006 oz
= Ag: 3,537,769 oz
= Zn: 65,642,277 lb

Inferred Resources:

32,443,840 t @ .78 g/t Au, 6.41 g/t Ag, .18 % Zn

= Au: 813,273 oz
= Ag: 6,691,185 oz
= Zn: 128,006,920 lb

At yesterday's gold, silver and zinc prices:

- Au: US$1432.80/oz
- Ag: US$35.67/oz
- Zn: US$1.1174/lb

The number of gold equivalents in the March 2011 NI 43-101 resource estimate is:

- Measured Resources: 218,410 oz Au-Eq. + 22,864 oz Au-Eq. + 19,911 oz Au-Eq. = 261,185 oz Au-Eq.  
- Indicated Resources: 624,006 oz Au-Eq. + 88,074 oz Au-Eq. + 51,193 oz Au-Eq. = 763,273 oz Au-Eq.
- Inferred Resources: 813,273 oz Au-Eq. + 166,579 oz Au-Eq. + 99,829 oz Au-Eq. = 1,079,681 oz Au-Eq.

Total: 261,185 oz Au-Eq. + 763,273 oz Au-Eq. + 1,079,681 oz Au-Eq. = 2,104,139 oz Au-Eq.

JDN's 80% interest = 1,683,311 oz Au-Eq.
MTB's 20% interest = 420,828 oz Au-Eq.
