SnapshotNova’s flagship Estelle Gold and Critical Minerals Project contains multiple resource centers across a 35km long mineralized corridor of over 20 identified gold prospects, including two already defined multi-million ounce resources.

Scoping Study 2023 considers a development based on multiple open pit mines at the Korbel Main, RPM North and RPM South deposits feeding a Estelle central processing plant located in the Korbel Mining Complex area.

Updated Mineral Resource estimation for the Estelle Project is planned in 2025.

Deposit type

  • Intrusion related

Summary:

Nova Mineral is primarily exploring for Intrusion Related Gold System (IRGS) type deposit within the Estelle Gold Project.

Estelle Project includes 3 deposits - Korbel Main, RPM North, and RPM South. RPM North and RPM South deposits are within 800m of each other and are located 27km south of the Korbel Main deposit.

The Korbel Main pit is located in a valley between two mountain ridges. The topography is somewhat steep. The overburden consists of a thin layer of moraine. The RPM North pit is located partially on the side of a mountain ridge and partially in a valley. There is some overburden on parts of the deposit in the valley consisting of moraines, other parts on the ridgeline consist of bedrock outcrops. The RPM South pit is located on a mountain ridge, with mineralization outcropping on the surface with little to no overburden.

Dimensions
The Main zone domain extends over around 2.6 km of strike at an average width of around 370 m. Modelled estimates extend from near surface to around 820 m depth with around 80% from depths of less than 500 m.

The two steeply west dipping West and East mineralised domains interpreted for Cathedral are interpreted over around 780 and 420 m of strike respectively with average horizontal widths of around 340 m and 110 m. Estimates extend from surface to around 500 m depth with around 90% from less than 380 m depth.

The combined mineralised domains strike east-west over around 740 m and average around 155 m wide. Resource estimates extend from surface to around 360 m depth with around 90% from vertical depths of less than 280 m.
