St George Gold-Antimony Project
The St George Gold-Antimony Project is located 70km west of Mt Carbine, North Queensland. The tenement package consists of 7 tenements comprising of 5 granted and 2 tenements in application for a total area of 905km2 within a developing Antimony province in the Hodgkinson Province.
Pacgold has the right to earn up to 100% interest in the project over a three-stage farm in agreement.
Project Geology
The St George Project lies within the Palaeozoic Hodgkinson Province of north-eastern Australia. The province consists of a clastic marine sediment sequence of which the Hodgkinson Formation is the most extensive unit. The Hodgkinson Formation consists of a thick, monotonous succession of very weakly metamorphosed greywacke, shale, slate, conglomerate, minor basic volcanics and chert, and rare limestone. The sediments commonly display turbidite-type sedimentary structures. The principal structural trend in the Province is NNW-SSE.
The Hodgkinson Province hosts widespread mineralisation with several main areas of past production including the Palmer and Hodgkinson goldfields, the Mt. Carbine tungsten field, and the Herberton tin-field. The Hodgkinson Goldfield was first mined for gold in 1876 and has a historic production of 0.3Moz gold and is located 40km to the SE of the St. George Project. The Palmer River goldfield was discovered in 1873 and has a historic production of 1.3Moz Au and is located 50km to the NNW of the Project. Mineral exploration for gold and antimony in the Hodgkinson Province has been undertaken sporadically over the past 150 years and was most prevalent in the 1980’s and in the early to mid-2000’s. A number of gold – antimony deposits were discovered and mined in the 1980’s, including the Tregoora and Northcote deposits which have since been mined by open cut.
St George Gold-Antimony Asset
The St George gold-antimony prospect contains mineralisation which occurs within a series of quartz-stibnite veins that crosscut a sequence of metasedimentary units of the Hodgkinson Formation, predominantly sandstones, greywackes, cherts and limestones. The veins are steeply dipping and occur in swarms up to 30m wide with individual veins mapped up to 3m in width at surface. The veins have been mined for stibnite in a hand dug open pit, a series of small shafts and pits and a shallow underground adit and workings to a depth of 30m below surface.
The mineralised vein system at St George has been mapped over a strike distance of at least 500m and is open along strike. No modern exploration besides rock chip sampling and mapping has been undertaken.
