West Perth, WA / November 27, 2017 / JMN Wire / Xanadu Mines Ltd (ASX: XAM) (“Xanadu” or “Company”) is pleased to provide complete assay results for diamond drill hole KHDDH430 from the White Hill deposit at Kharmagtai where drilling is targeting extensions of copper and gold mineralisation along strike and below the current resources.
New geological interpretations of the White Hill deposit have identified a zone of undrilled down-dip mineralisation which could add a significant volume of mineralisation to the Kharmagtai resource base. Drill hole KHDDH430 was designed to expand mineralisation south of, and down-dip of the current resource. This hole has added over 380m of previously unknown mineralisation. Importantly, this new zone of mineralisation is higher-grade than the majority of mineralisation within White Hill (Figure 3). Complete assay results have been returned from KHDDH430 with 850m @ 0.32% Cu and 0.2g/t (0.45% eCu) from surface including 282 @ 0.44% Cu and 0.16g/t Au (0.55% eCu) from 560m. The deeper parts of KHDDH430 contained significant potassic alteration and bornite mineralisation (Figure 4 & 5) suggesting this hole is vectoring towards deeper, higher grade porphyry copper and gold mineralisation. Additionally, the hole was terminated within a post mineral dyke indicating mineralisation should be open at depth, below this dyke.
3D magnetic inversions at White Hill show a compelling picture of a deep seated magnetic anomaly, interpreted to be a mineralised polyphase intrusive stock, feeding the shallower mineralisation at White Hill (Figure 6). Further drilling is underway to test for high grade bornite mineralisation within the potassic zone beneath White Hill.
Highlights
- Extensional drilling returns additional broad zone of mineralisation at White Hill;
- KHDDH430 intersected 850m @ 0.32% Cu and 0.2g/t (0.45% eCu) from surface including 282 @ 0.44% Cu and 0.16g/t Au (0.55% eCu) from 560m;
- Mineralisation has been extended +380m below and south of existing resource;
- Grade of new mineralisation is higher than that within the existing White Hill resource;
- Potassic alteration with bornite mineralisation increasing down hole potentially indicating a high-grade source at depth;
- White Hill mineralisation open to the east, west, south and at depth.
Xanadu’s MD & CEO, Dr Andrew Stewart, said “We are excited by this new drilling beneath the maiden White Hill resource as it has extended the zone of mineralisation but more significantly, it has intersected bornite and extensive potassic alteration which could be the precursor to the discovery of a higher-grade system adjacent to the established resources”.
