MORNING STAR MINE
Morning Star is a historic underground gold mine located approximately 120km east of Melbourne, Victoria within the prolific Walhalla to Woods Point dyke swarm goldfield with historical production in excess of 6 million ounces of gold.
Morning Star Mine
The Walhalla to Woods Point gold field is one of the most significant in Australian history with gold production having exceeded 6 million ounces. In the late 1950’s Morning Star was one of Australia’s largest gold mines having reportedly produced in excess of 800,000 ounces at an average grade of 26.5 g/t over its lifetime. The mine was owned and operated by Gold Mines of Australia (GMA) later merged into Western Mining Corporation (WMC).
Morning Star has, by historical production, displayed potential to deliver low-cost, high-grade gold production upon which to found major corporate expansion.
AuStar Gold acquired Morning Star Gold NL (MCO) in 2015, including the Morning Star mine and a large tenement holding with numerous other historic mines. At the time of the acquisition, the Morning Star mine had been fully refurbished to 10 level with numerous development drives rehabilitated in the upper levels for preliminary bulk sampling and trial mining activities.
During MCO ownership, a new 80,000 tonne per annum processing plant and associated paste backfill facility had been constructed. With the acquisition of MCO, AuStar has 100% ownership of the plant and has established all necessary supporting infrastructure including a high-speed winder, surface and underground power supplies, site offices and accommodation quarters. The facilities are permitted for tailings placement underground via the paste backfill plant, giving Morning Star the enviable position of being the only permitted processing plant on the entire gold field.
The mine exhibits narrow quartz vein deposits hosted in a diorite dyke that is 700m long by 120m wide. The quartz veins are stacked and range up to 2m thick. Historic workings continue underground for 815m below the surface, to 25 Level, and the dyke remains open at depth.

Gold from Morning Star is traditionally free milling allowing for the production of coarse free gold and high-grade concentrate using simple and cost-effective gravity separation. The coarse free gold is recovered, then smelted and poured into Dore (bars) onsite whilst the high grade concentrate can be processed via various options both domestically and internationally.
