The Ermine Project consists of 3 main prospects; Ermine, Ermine North and Echidna. The project is located approximately 45km SE of Charters Towers.
Ermine Project Location
The Ermine area was first identified in 1992 as an outcropping gossan while following up coincident airborne EM and stream sediment anomalies. Historic exploration identified significant VHMS‐style, zinc‐rich mineralisation in two deposits along a combined strike length of about 250 metres at Ermine and 300 metres at Ermine North.
The host rocks to the Ermine group of prospects are interpreted to be the upper boundary of the Mount Windsor Formation with the lower boundary of the Trooper Creek Formation, the same stratigraphic position as the Thalanga groups of deposits.
Historically, Forty one drill holes have been drilled at Ermine prospect for a total of 5,294m. Three main styles of mineralisation have been identified; Pyrite‐rich disseminated and stringer mineralisation in footwall felsic volcanics, volcaniclastic sediment‐hosted stratiform semi‐massive to massive sulphide mineralisation, and transported sulphides clasts in altered dacitic and andesitic fragmental volcanics.
Significant intercepts include: ERCD14A; 6.8m @ 14.05% Zn from 20.4m, ERC1; 12m @ 6.08% Zn from 32m and ERC11 4m @ 9.2% Zn from 47m.
The ore grade intercepts from the Ermine drilling are currently interpreted to represent massive sulphide clasts within talus, an accumulation of rock fragments at the base of a paleo slope, suggesting the Ermine prospect is proximal to a larger coherent zinc rich deposit. Recent mapping in the Ermine area has confirmed that the favourable horizon continues to the north east to the Echidna prospect where strong Cu-Pb-Zn soil anomalies and coincident IP anomalies remain untested by drilling. The Echidna prospect presents as an attractive zinc rich VHMS target for Red River and future exploration programs are currently being developed.
