Summary:
The Mt Garnet base metal mineralisation occurs in a garnet-pyroxene-amphibole skarn-altered, northerly-trending, fossiliferous limestone and limey siltstone unit that hosts sphalerite-rich mineralisation. The skarn zone dips sub-vertically, is typically 30 metres to 60 metres wide, and extends beyond 550 metres below surface, which is the current limit of drill investigations.
High-grade massive and semi-massive sphalerite-rich mineralisation (notionally >10% Zn) is largely confined to two distinct, sub-parallel, shallow to moderately north-plunging “shoots”, termed the South Shoot and the North Shoot.
Summary:
Mining operations recommenced at the Mount Garnet mine in July 2017, with the mining of remnant ore from the existing Mount Garnet underground mine in parallel with new development to the newly discovered Mount Garnet Deeps deposit located 70m south of the Mount Garnet mine. The Company commenced decline development from existing workings at the Mount Garnet underground mine to access the Mount Garnet Deeps deposit. The first extraction of ore from the Mount Garnet Deeps deposit commenced in December 2018.
Current mining activity is occurring at both the Mt Garnet Mine and the Dry River South (DRS) Mine at the Surveyor Project.
Development of the new Mt Garnet Deeps decline continued during the last quarter of FY2019 in parallel with ore drive development. Ore from the old Mt Garnet Mine continued with small quantities of remnant ore from the upper levels.
Increasing quantities of development ore will continue to be mined from the Mt Garnet Deeps deposit with stope production commenced in the first quarter of FY2020.
Extraction of Mt Garnet Deeps underground employs Longhole Open Stoping as the mining method with 20 m to 25 m level spacing. Development is achieved using CSD owned Atlas Copco M2D twin boom Jumbos. Longhole production drilling is achieved using CSD owned Sandvik DL432i Production Drill. Teleremote loading in stope is done by CSD CAT R1700 and R2900 loaders and ore is hauled to surface using CSD CAT AD55 articulated dump trucks.
