The Morning Star mining and exploration operations are centrally located within the Woods Point goldfield, about 116km north-east of Melbourne in Victoria. The mine was in production between 1862 and 1963. The main shaft, in-mine infrastructure, site-based processing facilities and haulage system at Morning Star have been undergoing refurbishment in preparation for full production that was scheduled to re-start in October 2011.
The Morning Star operations include the Hope, Cherry's Alps, North United and Age of Progress reefs. The mine workings extend across a vertical depth of 1100 metres and a strike length of 750m. The dyke ranges from 60m to 115m wide. The mine has been extensively worked from surface down to 50m, from 120m to 230m depth, and from 500m to 700m depth. The mine has been intensively mined in only 360m of the 1100 drilled depths, and these worked areas produced between 2000oz and 5000oz per vertical metre.
The quartz vein deposits of the Woods Point dyke swarm are considered to be particularly high-grade.
Operating. Shaft upgrade works involving reinforcing the shaft steelwork and installing ground support to ensure the structural integrity of the mine shaft were scheduled to be completed in first week of November 2011. Access back onto the levels enabled mine production at Morning Star to resume.
