Ravenswood Project
The Ravenswood Project is located to the south and east of Charters Towers in North Queensland and consists of five granted EPMs covering an area of 309 km2. The Ravenswood Project contains numerous prospects, historic drill intersections and geochemical anomalies located within the 17-million-ounce Charters Towers gold province including vein-hosted gold targets (e.g. Day Dawn, Pinnacle Creek) and Mount Leyshon style breccia pipe-hosted targets (e.g. Seventy Mile Mount, Matthews Pinnacle).
Tenements
The Ravenswood Project comprises five granted exploration permits - Mt Leyshon EPM 18424, Cornishman EPM 18426, King Solomon EPM 18637, Charlie Creek EPM 25466 and Birthday Hills EPM 25467.
Exploration Program
Day Dawn sits within the major east-northeast trending Mount Leyshon Corridor. The deposit was discovered by Ballymore and has reported high-grade gold, silver and lead mineralisation associated with stacked quartz veins. Rock chip samples have reported high grade results including:
- COR-270: 127.5 g/t Au, 708 g/t Ag & 2.83% Pb
- COR-305: 50.3 g/t Au, 7100 g/t Ag & 9.40% Pb
- COR-269: 71.8 g/t Au, 1460 g/t Ag & 2.76% Pb
- COR-267: 52.4 g/t Au, 1515 g/t Ag & 5.97% Pb
Rock chip sampling by Ballymore has defined an area of anomalous Au-Ag-Pb rock chip results over an area of 900m x 300m in the Day Dawn area. In addition, a soil sampling program has highlighted a large 1,400m x 300m gold-lead anomaly in the Day Dawn - Old Man area. Maximum soil results in the area include 1000 ppb Au, 1.97 ppm Ag, 330 ppm As, 29.4 ppm Bi, 360 ppm Cu, 372 ppm Pb, 75.5 ppm Sb and 498 ppm Zn.
Previous Mining
Mining within the Ravenswood District is dominated by Mount Leyshon, Ravenswood, Mount Wright, Hadleigh Castle and Charter’s Towers mines. The dominant mineralisation in the Ravenswood Project area is the Mount Leyshon gold-silver deposit. Mount Leyshon is located immediately adjacent to EPM 18424. Mount Leyshon operated from 1986 until 2002, and produced approximately 3.8 Moz of gold and 2.4 Moz of silver (Queensland Department of Mines and Energy, 2009). Much of the modern exploration in the region has been directed towards finding Mount Leyshon style mineralisation.
In addition, the Hadleigh Castle mine, is located 8 km east-northeast of EPM 18426. Hadleigh Castle is a complex swarm of quartz-polymetallic sulphide veins hosted in a major shear zone and has produced 350,000 oz Au from 3.15 Mt of ore averaging 3.45 g/t Au from underground and open pit operations.
Recent field work at the Day Dawn prospect, along strike from Hadleigh Castle has reported extensive veining in the area. Rock chip results have reported up to 127.5 g/t Au and 708 g/t Ag.
The Ravenswood Project tenements host numerous smaller scale hard-rock and alluvial gold mines.
