Production Start...
White Rock continued ramping up operations at the Woods Point Gold Mine Project resulting in the pouring of the Project’s first gold bar poured in October and first on site bar in early December 2022.

March 21, 2023 - White Rock Minerals Limited (WRM) informs the market that it has reluctantly placed its MorningStar Gold Mine at Woods Point into Care and Maintenance. Due largely to funding pressures, it was decided that it would be imprudent to continue to operate the mine.

Summary:

The Morning Star area lies within the Woods Point – Walhalla Synclinorium structural domain of the Melbourne zone, a northwest-trending belt of tightly folded Early Devonian Walhalla Group sandy turbidites. The domain is bounded by the Enoch’s Point and Howe’s Creek Faults, both possible detachmentrelated splay structures that may have controlled the intrusion of the Woods Point Dyke Swarm and provided the conduits for gold-bearing hydrothermal fluids. The local structural zone is referred to as the Ross Creek Shear Zone (RSZ).

Most gold mineralisation in the Woods Point to Gaffney’s Creek corridor occurs as structurally-controlled quartz ladder vein systems hosted by dioritic dyke bulges. The Morning Star Gold Mine exhibits all these characteristics.

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. The dyke has been mined to a depth of 920m with the dyke open at depth below 1,000 vertical metres.


Mining Methods

  • Narrow reef drill & blast
  • Paste backfill


Summary:

Morning Star is a historic underground gold mine. AuStar Gold acquired Morning Star Gold NL (MCO) in 2015. 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.

Following the completion of a successful trial mining program in the first half of the financial year, AuStar recommencedmining and processing activities at Morning Star in March 2019.

Mining operations continued through the 2020 financial year from the McNally and Stones reefs. Mining operates as a rail and shaft operation, with airleg mining/drill and blast operations and movement of ore to surface via carting.

Throughout the year McNally Reef contributed the bulk of Morning Star production with development made more challenging by the reef developing down-dip towards the east of original intersection and development. This reef development resulted in longer and multiple staged haulage, up incline, to the Seven Level rail heading, impacting production volumes.

Recent geological work has identified a development opportunity to develop from Eight Level to Seven Level, providing for future production from McNally Reef to occur largely down incline. This development is expected to materially increase production from McNally within existing resources.

Mining continued in the Stones Reef throughout most of ........
