Elizabeth Hill Silver Project Overview

Elizabeth Hill, one of Australia's highest-grade silver projects, has a proven production history outlined below:

· High-grades enable low processing tonnes: 1.2Moz of silver was produced from just 16,830t of ore at ahead grade of 2,194g/t (77.4 oz/t Ag).

· Previous mining operation ceased abruptly in 2000 because of low silver prices (US$5/oz)[1] and a dispute between the previous joint venture parties.

· Simplistic historical processing technique: native silver was recovered via low-cost gravity separation due to high grades and large silver nugget sizing.

· Untapped potential remains in and around the historic mine site, with limited, outdated drilling and geophysics deployed.

· Tier-1 Mining Jurisdiction - located on a mining lease with processing facilities adjacent at the nearby Radio Hill site.
