Name: Peak mine.

Location: The Peak mine is located in the northern part of the Cobar basin, in New South Wales, in Australia.

Mine Owner/s: Aurelia Metals.

Brief Description: Peak mine comprises several polymetallic underground mines, as well as a gold and base metals processing plant.

The primary areas being mined at Peak comprise the Chronos, Perseverance and Jubilee deposits. Chronos and Perseverance are accessed through a shaft and surface decline located at the Peak mine site. The Jubilee orebody is accessed through a decline near the base of the New Cobar openpit.

Brief History: Aurelia completed the acquisition of Peak mine from Toronto-listed miner New Gold in April 2018 for A$59-million. Through accelerated mining of the high-grade Chronos gold deposit, Aurelia achieved investment payback on this acquisition price within four months of acquisition completion.

Primary Metals/Minerals: The ore zones at Peak Mine are characterised as gold- and copper-rich.

Secondary Metals/Minerals: The ore zones are characterised as gold-rich, with copper/lead/zinc by-product credits in the southern mine corridor, and copper-rich, with gold/silver/lead/zinc by-product credits to the north.

Geology/Mineralisation: The Peak mine is one of a north-south cluster of structurally controlled gold, copper and lead/zinc deposits distributed along a linear, largely shear-controlled contact between two early Devonian units, the sandstones and siltstones of the Chesney Formation, and the overlying siltstones and mudstones of the Great Cobar Slate. This cluster of occurrences is distributed over an interval of about 11 km, with the Peak being near the southern end. This shear zone is close to the eastern margin of the Devonian rift into which these sediments were deposited.

Mineralisation at Peak is contained within the north-north-west-trending Peak shear, an anastomosing, thrust-type fault zone that is subparallel to the aforementioned contact described, and is about 3 km long and up to 300 m wide. It parallels the prominent regional cleavage and transects a series of parasitic folds on the regional anticline whose axis is to the west.

Reserves: Total mineral reserves as at June 30, 2020, were estimated at 3.33-million tonnes grading 2.3 g/t gold, 0.9% copper, 2.8% lead, 2.9% zinc and 16 g/t silver.

Resources: Total mineral resources as at June 30, 2020, were estimated at 11.35-million tonnes grading 1.5 g/t gold, 1.4% copper, 1% lead, 1.2% zinc and 10 g/t silver.

Mining Method: Mining is typically by open stope underground methods with backfill.

Major Infrastructure and Equipment: Mined ore is processed through an 800 000 t/y gold- and base metal-configured processing facility located at the Peak mine site.

Prospects: Drilling is currently focused on further extensions of the existing orebodies, further delineating the Kairos and Peak North deposits, and testing of potential high-value Peak line-of-lode targets.
