TORONTO, Nov. 20, 2024 (GLOBE NEWSWIRE) -- Xanadu Mines Ltd (ASX: XAM, TSX: XAM) (Xanadu or the Company) is pleased to announce strong surface copper assay results from its Sant Tolgoi Project located in Zavkhan Province of Western Mongolia (Figures 1 and 2). Geological mapping, surface rock-chip sampling and geophysics have confirmed the preference of several large anomalies associated with outcropping mafic intrusions. The objective of the multi-discipline exploration programme is to collect the data required to identify drill targets within the large Sant Tolgoi Intrusive Complex. Four targets have been identified and a total of 3000m of reconnaissance drilling has been planned to test all targets for high-grade massive sulphide copper and nickel.

Highlights

  • Reconnaissance rock-chip samples collected at the Sant Tolgoi project have returned high-grade results of up to 2.1% Cu from multiple gossan outcrops

  • Detailed mapping, geophysics and geochemistry defines at least 4 high-priority drill targets over a 4-kilometre-long splay off the Khangai Fault System

  • Follow-up drilling to commence in Q2 2025

Xanadu’s VP Exploration, Dr Andrew Stewart, said:

“We are very excited about the latest results from the Sant Tolgoi exploration program which was designed to collect data required to identify drill targets. Our exploration strategy at Sant Tolgoi focuses on outcropping mafic intrusions where anomalous assay results and detailed geophysics has defined four targets within 100-metres of surface.

“This project represents an exciting greenfields opportunity, and is potentially a new Magmatic Cu and possibly Ni-PGE District in an under-explored mineral province of Western Mongolia. These latest results validate and refine our exploration models providing our exploration team with a clear direction towards a significant discovery at Sant Tolgoi. Follow up drilling is planned for the first half of 2025.”

High-Priority Targets Identified

Four key targets have been identified, based firstly on favourable geology and co-incident strong geochemistry, supported by the geophysical properties indicative of mineral deposits.

Geochemistry defined four distinct copper targets at surface. Target 1 consists of outcropping copper oxides (Malachite and Azurite) up to 1% copper in assays with mineralisation associated with coarse grained gabbro stock covering a 500m x 300m area. This area sits within a fault jog on a splay off the Khangai Fault System, where dilation could have created space for mineralised intrusions. Magnetics show a strong remanent magnetic feature in 3D suggesting the target consists of an intrusive rock, or rock that has been altered or mineralised by hydrothermal fluids. Gravity data shows a strong density contrast with surrounding rocks, indicative of a denser, potentially mineralised intrusive. A Dipole-Dipole Induced Polarisation (DDIP) line that crossed the target shows a relatively strong 20mV/V IP chargeability anomaly directly below the geochemistry, indicative of disseminated sulphides in a mineralised intrusive. Controlled source audio-frequency magnetotellurics (CSAMT) data also shows a conductive zone associated with the center of this Induced Polarisation (IP) Chargeability anomaly, potentially massive sulphide, surrounded by a resistive halo.
