LARGEST UNDEVELOPED SILVER MINE IN AUSTRALIA, page-470

UPDATED MINERAL RESOURCE ESTIMATE FOR BOWDENS SILVER DEPOSIT

HIGHLIGHTS

• The Bowdens Silver Deposit Mineral Resource estimate for all categories has been upgraded to:

  200 million tonnes @ 62g/t silver equivalent (‘Ag Eq’)1 (29g/t Ag, 0.37% Zn, 0.26% Pb, 0.07g/t Au at a 30 g/t Ag Eq cut-off) for 396 million ounces Ag Eq.

• Compared to the 2017 Mineral Resource estimate this resource represents a:  56% increase in total tonnes

   44% increase in total silver equivalent ounces

• Measured and Indicated Mineral Resource categories are 79% of total Mineral

  Resource estimate tonnage.

• The updated Mineral Resource estimate will be used to optimise open-cut mine

  studies and drive Mineral Resource to Ore Reserve conversion.

• The Mineral Resource estimate includes 19 million tonnes @ 0.31 g/t gold for 190,000

  ounces of gold (at a 0.2g/t gold cut-off).

• The addition of gold to the Mineral Resource estimate adds significant value to the

  project.
