Big River

Big River Project – Overview

Exploration Strategy – Alexander River

Tenement: EP 60448

Area: 44.87km2

Ownership: 100%

Historical Production: Big River closed in 1942 due to WWII. Historical production of 136koz @ 34.1g/t Au (cut off grade ~15g/t Au). Mined to 560m from 12 levels

4km+ Anomalous Strike Length

The Big River gold project consists of 6 identical gold mineralised shoots across more than 500m of strike, with the potential to discover additional high-grade shoots.

Maiden Mineral Resource Estimate

Inferred MRE 105koz @ 3.94g/t Au at a 1.5g/t cut-off (Shoot 4 & A2 Shoot only).

The Big River deposit remains open in all directions with significant potential for increased gold resources from additional exploration drilling.

Historical Productions

  • Big River project lies 15km south-east of Reefton and includes the historic Big River Mine, which produced ~136,000 oz of gold at an average recovered grade of 34g/t between 1880 and 1942 down to 550m.
  • Four main ore shoots were mined (Shoots 1-4) with two potential unmined shoots; the A2 and Prima Donna, located east and west of the Big River mine.
  • The A2 shoot, Big River Mine and Prima Donna shoot combined cover a strike length of around 500m, which is overlaid by anomalous gold and arsenic soil geochemistry.
