The mineralisation style is volcanogenic hosted massive sulphide (VHMS) which occurs as sub-vertical lenses within layered sediments and volcanics.

The Golden Grove deposits are located in the Murchison Province in the NorthWestern part of the Achaean Yilgarn Craton in Western Australia within the Yalgoo Greenstone Belt. Mineralisation occurs at the base of the Warriedar Fold Belt (“WFB”) within a sequence of felsic to intermediate volcaniclastic sediments, lavas and associated autoclastic breccias.

The Golden Grove Domain that hosts the Gossan Hill and Scuddles deposits lies along the northeast flank of the WFB. The Mougooderra Fault (west), recrystallised monzogranite (east) and post folding granites (north and south) bound the domain. The current interpretation of the structure places the Golden Grove Domain on the eastern limb of a syncline. The stratigraphy has a westerly younging direction and dips steeply west.

The primary sulphide mineralisation at Gossan Hill and Scuddles comprises multiple steeply dipping zones. Each zone varies from 200m to 400m along strike, 200m to 700m down-dip and 3m to 20m in thickness.

Oxide gold mineralisation is approximately 600m long and was reported above the 10200mRL.

Golden Grove is a Volcanic Hosted Massive Sulphide (“VHMS”) camp consisting of Gossan Hill and Scuddles underground mine operations made up of 20+ individual sulphide lenses in three mineralised horizons.

The Gossan Hill underground mine is served by an extensive ramp and drift system to access the ore. Ore from Scuddles is assessed by shaft and ramp. [https://sikaconcrete.co.uk/case-studies/golden-grove-mine-western-australia/]

Underground operations are contracted to Byrnecut Group Services.

Mining Method: sub-level open stoping. [https://www.minesandprojects.com/reports/GoldenGrove-article-09292017.pdf]

Ore is processed by crushing and grinding the ore to liberate the valuable minerals that contain the copper, zinc, lead, gold and silver. Ore throughput is 1.7Mt per annum producing three separate saleable concentrate products; copper concentrate, lead and precious metals concentrate and zinc concentrate.

Ore is transported by conveyor and stockpiled. Stockpiled ore is taken to the mill where it is broken down further using a two-stage wet grinding circuit that includes a primary semi autogenous grinding (SAG) mill and secondary ball mill, cyclone cluster and a pebble crusher to treat oversize material from the SAGmill.

In 2019 secondary crusher installed to enable initial production increase to 1.7mtpa expanding to 2mtpa. [https://www.emrgoldengrove.com/site-location-and-history/]

Concentration of valuable minerals occurs via standard froth flotation.
