Name of the Mine
Tampia mine.

Location  
Tampia mine is located 12 km south-east of Narembeen, in the Western Australia wheat belt, and 250 km east of Perth.

Mine Owner/s  
Ramelius Resources.

Brief Description  
Tampia is a gold mine based on the staged development of a single openpit.

Brief History  
Mining started at Tampia in May 2021, with ore processing starting two months later.

Primary Metals/Minerals  
Gold.

Secondary Metals/Minerals  
None stated.

Geology/Mineralisation  
The Tampia mine area comprises a sequence of mafic and felsic granulite facies paragneiss and orthogneiss similar to the regional area, with the gold deposit hosted by an ovoid-shaped mafic gneiss sequence that has been mapped in detail using ground gravity data and drilling.

The gneiss sequence dips between 35° to 40° to the south-east and strikes 040°. The base of the gneiss sequence that host the Tampia gold deposit, as interpreted from the structural position of the host rocks, is a well-banded foliated and banded felsic feldspar/biotite/quartz augen gneiss that can also contain graphite and pyrrhotite. The original sequence for this unit is believed to be clastic sediment, wacke, arenite and graphitic shale. The next unit is a felsic feldspar/biotite/amphibole/pyroxene gneiss that appears to contain a mixture of sedimentary and mafic precursor lithologies.

Gold mineralisation at Tampia is spatially associated with tabular zones of intense silicification accompanied by microcline, hornblende and massive, green clinopyroxene. These zones also tend to be associated with a well-developed crenulation cleavage. Gold mineralisation occurs predominantly in the chemically reactive iron-rich mafic gneiss, but rarely in the late undeformed granites along their contacts; it also occurs as narrow lower-grade intersections with the undeformed granite. This confirms that gold mineralisation post-dates the intrusion of the granite sheets. From this, it is inferred that the metamorphic and structural architecture was established prior to gold mineralisation. No gold has been found to date in the lower felsic gneiss units.

Reserves  
Total mineral reserves as at June 30, 2022, were estimated at 1.9-million tonnes grading 1.9 g/t gold.

Resources  
Total mineral resources as at June 30, 2022, were estimated at 5.4-million tonnes grading 1.6 g/t gold.

Mining Method  
Openpit.

Major Infrastructure/Equipment  
Ore processing is undertaken at the Edna May mill using standard gravity and carbon-in-leach processes.

Prospects  
Tampia has become a key contributor to Ramelius’ production profile.
