Twangiza Data

Twangiza Information

  • Mineralization 2015-08-03
    The Twangiza area is underlain by sediments of Proterozoic age that have been intruded by porphyry sills, folded into a series of broad anticlines and synclines and subjected to very low-grade metamorphism. The gold mineralization at the Main Twangiza deposit is hosted within mudstones, siltstones, greywackes and porphyries along the crest of a major anticlinal structure. Gold mineralization is of hydrothermal origin and is associated with sulfides which occur in quartz-carbonate veins, and disseminations throughout the host rocks. Unlike the Twangiza Main deposit, the mineralization at Twangiza North is associated predominantly with feldspar porphyry sills that have intruded westerly dipping shales and siltstones, with the mineralization in this lithology being non-refractory.
  • History 2015-08-03
    The Twangiza gold deposit was discovered by Miniere des Grande Lac (MGL) in the 1950s. The company followed the occurrence of alluvial gold deposits upstream from the Mwana River to the present-day Twangiza deposit. MGL tested the deposit through 8,200 metres of trenching and 12,100 metres of adits on seven levels, collecting a total of 17,400 samples. In the mid-1970s, Charter Consolidated undertook detailed exploration, including the excavation of numerous close-spaced adits into the mineralized zone. In 1996, Banro acquired control of the Twangiza property, and during the following year, undertook a US $9 million exploration program, which included 10,490 line-kilometres of airborne geophysics, 1,613 samples from 16 adits, and 8,577 drill core samples from 9,122 metres of core drilling along 800 metres of strike. This represented less than 20 percent of the identified mineralized trend.
  • General 2015-08-03
    Twangiza (Oxide) became Banro's first producing open pit gold mine when it entered production in October 2011, commencing commercial production in September 2012. With mill throughput at full capacity of 1.7 million tonnes per year, Twangiza (Oxide) is projected to produce upwards of 10,000 ounces of gold each month with an expected mine life of fourteen years from currently-defined reserves
