Horizon Minerals (ASX:HRZ) said scoping studies found an "attractive" gold development opportunity with an average annual gold production of about 102,000 ounces at its Black Swan project processing hub in Western Australia, according to a Tuesday Australian bourse filing.

The company said that the study found a gold development opportunity with low capital intensity, utilizing existing mining and Black Swan processing infrastructure.

The company said that the mine plan contains approximately 74% measured and indicated resources, with the balance as inferred resources.

The majority of mineral resources are located on granted mining leases with major approvals either completed or well underway, which assists with expediting the commencement of mining activities.
