RHA Project: Producing Tungsten Mine
The RHA Project is located in an area of historic production, approximately 270km northwest of Bulawayo. Premier ihas brought RHA from exploration status to production status. In 2016 we produced our first concentrate. RHA employs a simple gravity seperation process route for recovery of tungsten minerals. Sample head grade from recent sampling was 1.52% WO3, wolframite is the dominant tungsten bearing mineral with 1.28% of the recent sample being wolframite and 0.28% being scheelite. Furher met testwork is underway
The project comprises 50 Mineral Claim Blocks, covering 1,800 hectares, consisting of 10 owned by Premier and 40 which are under option. Small-scale surface and underground mining was conducted at the site between 1931 and 1979. Total production from the RHA and Tung Mines was 1,247.65 tonnes of wolframite concentrate, containing 65% WO3.
The deposit is approximately 800m in strike length and 300m wide. Historic non-compliant Exploration Target estimates of the surface open cast, low grade mineralisation, as well as low grade overburden and higher grade underground resources below the 926m level, suggest that approximately 100,000 tonnes of ore may be available, grading at 0.75% WO3.
Accessible from the main Bulawayo-Hwange tar road, RHA has good potential to be brought into production rapidly with a favourable stripping ratio.
