Volume 14 • Issue 4 | 2017 | ASIA Miner | 29 THREE new large porphyry centres have been confirmed under shal- low cover at Xanadu Mines' Kharmagtai Copper-Gold Project in south- ern Mongolia. Recent drilling of high-potential copper-gold and gold targets has confirmed the centres. Detailed alteration and geochemical modelling has highlighted exten- sive system preservation while new gravity infill data is aiding under- cover targeting. The 19 high-potential copper-gold and gold targets generated during a recent bedrock drilling program are being tested with three core rigs drilling and only six targets tested to date. Outstanding initial drill results from the program indicate a 6km-long strike potential for mineralisation. The results have confirmed three of the targets as new large porphyry centres with at least one shallow drill hole in each target returning broad zones of porphyry alteration and mineralisation. Target 3 is a 650x550 metre porphyry target characterised by strong copper-gold anomalism and concentric porphyry veining and alteration zoning. Two shallow drill holes have been drilled with one hole returning 44 metres from 25 metres @ 0.19% copper and 0.27 g/t gold. Target 4 is a large circular porphyry target of 800x750 metres charac- terised by strong surface copper-gold with concentric porphyry veining and alteration zoning. Several shallow RC and DDH drill holes have been drilled at this target returning broad intercepts of porphyry-style mineralisation. Best results are 91 metres from 30 metres @ 0.22% copper and 0.26 g/t gold; 80 metres from 31 metres @ 0.19% copper and 0.21 g/t gold; and 90.1 metres from 26.9 metres @ 0.20% copper and 0.14 g/t gold, including 8 metres from 29 metres @ 0.44% copper and 0.50 g/t gold. Target 6 is a 1km-long x 400 metre-wide porphyry target characterised by anomalous surface copper-gold and zoned porphyry veining and alteration. One hole targeted the confluence of copper-gold geochem- istry and a bullseye magnetic anomaly encountering gold-rich porphyry style mineralisation returning 96 metres from 95 metres @ 0.35 g/t gold and 0.10% copper. It is believed this hole has tagged the edge of a significant porphyry system. Drilling continues and the remaining targets will be tested over the com- ing months before all targets are assessed to focus the drill rigs on the highest grade and largest systems. Xanadu confirms large porphyry centres Placement raises $15.4 million Xanadu has completed the bookbuild for a placement to institutional and sophisticated investors raising approximately A$15.5 million. The placement was heavily oversubscribed, reflecting the strong interest from a variety of existing and new investors. Xanadu said this was driven by its recent exploration success at the flagship Kharmagtai project. Xanadu's CEO Dr Andrew Stewart said, "The strengthening of our bal- ance sheet to now be debt free will allow Xanadu to vigorously pursue its drilling programs unencumbered, which puts us at a very advanta- geous position." Placement proceed will be used for exploration at Kharmagtai, Red Mountain and Yellow Mountain copper-gold projects. Tsurumi KTZ-series 15 kW Debut!! -- Tsurumi Submersible Heavy-duty Drainage Pumps -- Two 15 kW models have been added to Tsurumi's flagship KTZ-series of submersible pumps which support a product lineup of models ranging from 1.5 to 11 kW. The new models are available in two types: KTZ415 (4-inch) and KTZ615 (6- inch). These pumps provide a maximum head of 55 m and maximum capacity of 2.8 m3/min. Built with a cast iron body and high-chromium cast iron impeller, these pumps are advantageous in terms of durability and wear resistance. As the discharge design of these pumps, a top discharge side flow structure is used, which enables the slim body to be installed in a confined space and also ensures extended operation at a low water level. Owing to these features, the KTZ- series qualify as heavy-duty, highly- reliable and continuous duty pumps that are suitable for harsh work environments such as mining, quarrying, construction and tunnel work sites. Also, the Tsurumi's original (design registered) multi-directional hose coupling structure enables flexible on-site setup for either vertical or inclined discharge with just a wrench. Like all general submersible pumps from Tsurumi, these pumps are equipped with an anti-wicking cable, motor protector, dual inside mechanical seals with silicon carbide faces, and Oil Lifter as standard equipment. Furthermore, as found on 7.5 kW and higher motor output models of the KTZ- series, the 15 kW models have seal pressure relief ports in the pump unit, which prevent pump pressure from being applied to mechanical seals. In developing the new models, KTZ 15 kW, double bearings were provided at the bottom, as a thorough countermeasure against thrust load that may become a major factor of a pump fault. The shaft has undergone quenching treatment to increase hardness and ensure stability. These features are the results of original technologies and unmatched know-how that Tsurumi has cultivated over years of manufacturing pumps for construction purposes, so we firmly believe that you can assuredly use our pumps.
