Ravenswood Project
The Ravenswood Project is located to the south and east of Charters Towers in North Queensland and consists of six granted EPMs covering an area of 370 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).
Ravenswood field work
Further reconnaissance mapping and rock chip sampling was undertaken around the Day Dawn, Old Man and Pinnacle. Mapping and prospecting was also completed on the newly granted Mabel Jane licence as well as Charlie Creek. Soil sampling programs were completed within the Mabel Jane licence and further soil sampling was undertaken to extend the major 5km x 4km Pinnacle gold-in-soil anomaly.
Ballymore completed an initial RC drill program at the Day Dawn prospect, 25 km east-southeast of Charters Towers, comprising 11 holes for 1,360m. Drilling encountered a number of quartz-carbonate-pyrite-arsenopyrite veins and andesite dykes in sheared granodiorite and volcanics, in line with what had been mapped in the area.
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.
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.
