RHA comprised 50 mineral claim in the 1800 Ha, consisting of 10 owned by Prem and 40 under option.
Small-scale surface and underground mining was conducted at the site between 1931 and 1979, with total production from the mine is standing at 1 247,65 tonnes of WO3 in concentrate containing 65 percent APT.
Intermittent small scale mining was carried out at both RHA and the adjacent much smaller Tung mine (which Prem had an option over at the time) between 1931 and 1979. The mines jointly produced 1,247 tonnes of wolframite concentrate at an average concentrate grade of 65% WO3. So perhaps 80,000mtu was produced at RHA which today would have a sale price of just $210m.
The mine workings were almost entirely carried out during the 1930s where the underground mine which was accessed via the two adits in the sides of the ridge and a single vertical shaft down to the 845m level. Some open pitting was also carried out mainly in the western part of the strike.
During the mid to late 1970s Falconbridge Ltd, trading as Blanket Mines in Zimbabwe, carried out underground geological mapping and extensive channel sampling on the accessible parts of the underground workings, principally on the 926, 895 and 859 levels. Their exploration work had to be curtailed . But undoubtedly this mapping together with any previous data would have formed an integral part of Prems due diligence and would have helped in the preparation of RHA’s first Scoping Study which was to be completed later in 2013.
Prem joined the AIM market mid December in 2012 and by that time it had purchased RHA in a j.v. with the Governments Fund NIEEF by necessity.
