The Kalavassos Project comprises a single licence covering the entire Kalavassos Mining District on the southeastern flank of the Troodos Mountains (see ASX 29/05/2014). Thirteen (13) copper-rich pyrite bodies were discovered and mined from 1937 to 1977. Total production is recorded as 4,680,900 tonnes at between 0.5 and 3.0 %copper, including 4.62 million tonnes at >1.0 % copper. Gold and silver assays from the pyrite bodies are not known, but 61,450 tonnes of oxide material was mined between 1937 and 1943 to produce 16,490 ounces gold (8.3 g/t gold) and 34,740 ounces silver (17.6 g/t silver). Official records also refer to a combined total of 2.28 million tonnes of massive sulphide being left in some of the mines at unspecified copper grade. All of the stated grades and tonnages were collated by the Cyprus Geological Survey Department using historic annual production and reserve figures and do not comply with the JORC standard. A large amount of historic material, including surface and underground maps and plans, has been obtained from the Cyprus Geological Survey Department’s archive. Most of this material has been converted to digital format and captured in BMG’s GIS. The geological information is currently being verified and high-impact drill targets defined.
