High Priority Copper Drill Targets Defined at Sant Tolgoi

GlobeNewswire11-20 21:58

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.

Target 2 is outcropping copper (up to 2.1% Cu) mineralisation associated with coarse grained gabbro sill like body along the structure and covering a 300m x 50m area. Magnetics show a moderate remanent magnetic feature in 3D suggesting the target consists of an intrusive rock, or rock that has been altered or mineralised.  Gravity data shows a strong density contrast with surrounding rocks, indicative of a denser, potentially mineralised intrusive. A DDIP line that crossed the target shows a moderate 17mV/V IP chargeability anomaly directly below the geochemistry, indicative of disseminated sulphides. CSAMT data also shows a conductive zone, potentially massive sulphide in an intrusive.

Target 3 is a blind geophysical target under the cover. Target has high density and moderate magnetic features similar with targets have outcropping copper mineralization. The size of anomaly is 300m x 200m.

Target 4 is a blind geophysical target. Target has high density and moderate magnetic features similar with targets have outcropping copper mineralisation. The size of anomaly is 400m x 300m.

Geochemistry Sampling Results

The Sant Tolgoi surface sampling programme consisted of 519 surface rock-chip samples. Sampling was conducted over a 3km by 1km area (Field Area, Figure 2) covering two clusters of prospective rocks adjacent to the regional scale Khangai Fault System, interpreted to be channelling mineralisation in the area. Each sample consisted of numerous golf ball sized chips taken from a 2m-by-2m area. These samples identified outcropping copper mineralisation associated with coarse grained (1cm to 2cm grain size) gabbro dykes and stocks (Figures 2 and 3). Results confirm four distinct targets sitting in a 4-kilometre-long splay off the Khangai Fault System with elevated grade of copper up to 2.1% Cu and with association of <4g/t Ag; and <0.06% Ni at surface (Figure 3).

Geophysical Programme

Four geophysical properties have been measured to support drill targeting of surface geological and geochemical data. Magnetic data has been acquired to help identify and separate different rock types at depth. Gravity data has been acquired to potentially map denser intrusive bodies. CSAMT has been acquired to map conductivity which may correlate with linked sulphides (massive and veined) or structures containing water/conductive geological units. Dipole-Dipole Induced Polarisation data has been collected to identify disseminated sulphides (Figures 4 and 5).

Figure 5: Magnetic Inversions. See text for descriptions.

A total of 53-line kilometres of drone-based magnetics has been completed across the target area (Figure 4). This data has been inverted in 3D and processed to separate out the three component magnetic vector data. Amplitude data from the three components maps the true location of the magnetic susceptibility feature. The E-perpendicular component maps the remanent magnetic changes which occur after the host rock was formed. Processes like intrusives, alteration or mineralisation. The E-Projected component maps the background geology.

A total 530 stations of ground gravity survey completed over potential prospects of Sant Tolgoi Project. A moderate to high dense domains mapped the distribution of mineralized gabbro stocks or sills (Figure 4).

A total of 9 lines or 150 stations of CSAMT was completed over potential prospects of Sant Tolgoi Project. A low resistivity (conductive) feature mapps the gabbro stocks or sills in depth (Figure 5).

A total 4-line kilometres Dipole-Dipole Induced Polarisation survey completed over potential prospects of Sant Tolgoi Project. High chargeable and low resistivity features endorsing the above geophysics results in depth, where defined gabbro stock or sills (Figure 5).

Geology and Mineralisation

Mineralisation at Sant Tolgoi consists of copper oxides hosted within coarse grained gabbro. Copper is expressed as secondary, remobilised by weathering in fractures and as staining. This is interpreted to have been remobilised from primary disseminated and massive sulphides below the weathering profile. Figures 6 and 7 show polished slab photographs of the coarse-grained hornblende gabbro.

About Sant Tolgoi

The Sant Tolgoi Project covers two Exploration Licences, XV-17774 (Oyut) and XV-21887 (Sant Tolgoi) in the Zavchan Province of Western Mongolia with a combined area of over 40km2 (Figure 2), collectively referred to as the Sant Tolgoi Project or Sant Tolgoi Copper Project. The Tenement portfolio includes numerous advanced exploration targets with real prospectivity for the discovery of significant magmatic copper and nickel mineralisation. In the Zavchan Region of Mongolia, the Sant Tolgoi Project lies on the western extension to the of the deep seated Khangai Fault systems, a metalliferous fault network which hosts several significant mafic and ultramafic intrusions that are highly encouraging for intrusion hosted copper and nickel discoveries. Early signs of several copper-nickel systems have been encountered in both historical drilling.

Sampling techniques
  • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.
  • Samples were taken as surface rock chip samples.
  • 3kg of material was collected using geological hammer as numerous small golf ball sized chips over a 2m-by-2m area.
  • Samples were collected on a rough 50m- by-50m grid over areas of interest.
  • Samples were selected from as many rock types as possible.
Drilling techniques
  • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).
  •  No drilling has been completed on the project.
Drill sample recovery
  • Method of recording and assessing core and chip sample recoveries and results assessed.
  • Measures taken to maximise sample recovery and ensure representative nature of the samples.
  • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.
  •  No drilling has been completed on the project.
Logging
  • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.

Exploration
done by
other
parties
  • Acknowledgment and appraisal of exploration by other parties.
  • Previous exploration was conducted by Mongolian and Soviet Geologists. Limited other exploration has been conducted.
Geology

 
  • Deposit type, geological setting and style of mineralisation.
  • The mineralisation is characterized as Magmatic Cu-Ni mineralisation.
  • Magmatic Cu-Ni deposits are formed from magmatic hydrothermal fluids typically associated with mafic intrusive stocks or sills that have deposited metals as sulphides both within the intrusive and the intruded host rocks. The disseminated sulphides occurring both within the mafic intrusives and thought out the wall rock. The massive sulphides as lode may occur at the bottom of mafic intrusive bodies. Magmatic Cu-Ni deposits are typically low to high grade, moderate tonnage deposits are generally mined by shallow open pit mining method. The deposits at Sant Tolgoi are a typical in that they are associated with mafic intrusions of gabbro to hornblendite composition.
Drill hole
Information
  • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
  • Rock-Chip data, geological mapping, drone magnetics, gravity, CSAMT and DDIP data are the main sources of data for the project top date.
  • No Drilling has been conducted on the project to date.
  • See figures in ASX/TSX Announcement.
Data
Aggregation methods
  • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.
  • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.
  • The assumptions used for any reporting of metal equivalent values should be clearly stated.
  • No cut-offs or equivalent metal calculations have been used.


Relationship between mineralisation
on widths
and intercept
lengths
  • These relationships are particularly important in the reporting of Exploration Results.
  • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
  • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).
  • No drilling has been conducted.
  • No intervals have been reported.
Diagrams
  • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being  reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.
  • See figures in ASX/TSX Announcement.
Balanced
Reporting
  • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.
  • A full spreadsheet of the assay results received to date has been included in the body of the report.
