Empire also holds a portfolio of three precious metals projects located in a historically high-grade gold production region comprising the Rotgulden, Schonberg and Walchen prospects in central-southern Austria.
Empire has undertaken intermittent field work and confirmatory surveys at each project. At Schonberg the Company completed extensive soils surveys, underground chip and channel sampling, and surface reverse circulation drilling. A 3000m drill programme in 2014 tested for deep massive sulphide mineralization at three targets, with interesting results including, for example, 2m @ 2.26 g/t Au and 0.8% Cu from 129.5m
Walchen is a volcanogenic massive sulphide (VMS) deposit with historical production from the 1940’s which averaged 1.7% Cu, 3.2% Zn, 2.5% Pb, 83 g/t Ag and 0.5 g/t Au. Empire has completed surface sampling and other reconnaissance works at the project.
The Company has completed significant studies at the Rotgulden gold and precious metals project. This prospective 51 sq km licence area has four principal target areas – Rotgulden, Altenberg, Schurfspitze, and Wandstollen. Multiple targets were identified from aerial EM/magnetics surveys over a strike length of 27km. Empire has completed 1,335m of resource drilling in over 25 holes, with some excellent high-grade intercepts (eg. 3.9m @ 51.5 g/t Au, 238 g/t Ag, and 2.69% Cu), but grades are highly variable reflecting the complex nature of the mineralised structure.
In 2020 the Company completed a programme at Altenberg comprising sampling of old mine waste dumps, confirming and extending previous results with high grades of gold, silver, copper and lead. Estimation of mine dump volumes was also completed. The results indicate the presence of an extensive hydrothermal system with stockwork mineralisation and local enrichment zones. Of the 58 samples collected, 19 had gold grades between 4.79 g/t Au and 31.9 g/t Au.
