DRILLING UNDERWAY AT RED MOUNTAIN PROJECT
27 March 2024
Xanadu Mines Ltd (ASX: XAM, TSX: XAM) (Xanadu or the Company) is pleased to advise an initial
5,000m diamond drilling programme to test five main target areas at the highly prospective 100% owned
Red Mountain copper and gold Project in the South Gobi region of Mongolia is now underway, with drilling
expected to be completed by mid-May, and all assays available by end-June.
Highlights
dot Exploration drilling focused on discovery of shallow high-grade gold and copper-gold deposit, akin
to the shallower parts of the Northparkes copper gold porphyry deposits in NSW, Australia .
dot Systematic diamond drilling program designed to test five high-priority targets, following up on more
recent trenching and previous drilling; compelling results from the latter are highlighted, below:
dot First results from the drilling program are anticipated late April.
Xanadu's Executive Chairman and Managing Director, Mr Colin Moorhead, said,
"Drilling has commenced at our 100% owned Red Mountain copper and gold project with an initial 5,000m
diamond hole programme targeting five of our highest priority targets. Red Mountain offers a rare
opportunity to access a large, under-explored mineral district. We are conducting a systematic
exploration program, including diamond drilling, that we expect will provide a new perspective on the
mineral potential of the Red Mountain district. Xanadu is entering an exciting period of new opportunities
for discovery and growth."

Current Drilling Program: Three shallow drill holes and one deeper drill hole are planned to follow up on
these results. Shallow holes are targeting around the high-grade copper intercept in OUDDH089 and are
designed to determine the orientation of this zone, with the aim of delivering further expansion. A single
deeper hole is planned to scissor the broad porphyry intercept in OUDDH090, testing the theory that this
is associated with a south dipping structure, clearly visible in the magnetics (Figure 5)

Nowie Porphyry Porphyry Cu-Au Target
No work has previously been conducted at Nowie by Xanadu. However, multiple drill hole collars and
trenches from previous explorers are visible at surface. Soil sampling at Nowie has defined a 500m long
copper in soil anomaly greater than 0.1% Cu and 0.25g/t Au. Geological mapping has identified strong
oxide copper at surface associated with porphyry veining.
Current Drilling Program: Three diamond drill holes have been designed to test beneath the 500m
strike of surface mineralisation.

Stockwork Porphyry Porphyry Cu-Au Target
Limited work has previously been conducted at Stockwork by Xanadu. However, like the Nowie propsect,
multiple drill hole collars and trenches from previous explorers are visible at surface. Soil sampling at
Stockwork has defined a 650m long copper in soil anomaly greater than 0.05% Cu. Geological mapping
has identified strong oxide copper at surface associated with intense porphyry veining and a
reinterpretation based on this mapping has suggested an alternative orientation to drill test for the system
at Stockwork.
Current Drilling Program: Three shallow diamond drill holes have been designed to test this target.
About Red Mountain
The 100% owned Red Mountain project, located within the Dornogovi Province of southern Mongolia, approximately
420 kilometres southeast of Ulaanbaatar (Figures 1 and 2).
The project covers approximately 57 square kilometres in a frontier terrane with significant mineral endowment and
has a granted 30-year mining licence. Red Mountain comprises a cluster of outcropping mineralising porphyry
intrusions which display features typically found in the shallower parts of porphyry systems where narrow dykes
and patchy mineralisation branch out above a mineralised stock. This underexplored porphyry district includes
multiple porphyry copper-gold centres, mineralised tourmaline breccia pipes copper-gold/base metal skarns and
high-grade epithermal gold veins.
Existing porphyry mineralisation at Red Mountain is hosted within narrow stockwork zones that have been focused
around several narrow structurally controlled monzonite porphyry dykes. Emplacement of mineralisation appears
to be controlled by intersection of northeast and north-northwest trending structures. The quartz-chalcopyrite-
bornite stockwork mineralisation is associated with strong reddening albite-sericite-biotite-magnetite (potassic)
alteration assemblage in the host lithology. The thin nature of the mineralising dykes, their irregular intrusion
geometry, and the patchy distribution of stockwork mineralisation are all features typically found in the shallower
parts of porphyry systems, where narrow dykes and patchy mineralisation branch out above a mineralised stock.
Similar orebody geometries are found in the shallower parts of the Northparkes porphyry copper-gold (Cu-Au)
deposits in NSW, where porphyry mineralisation has also been tightly focused along a controlling structure adjacent
to a felsic pluton. Like Northparkes, there is the potential for further mineralisation along the main structures at
Diorite Hill and Stockwork Hill, and the likelihood that mineralisation extends (and could amalgamate) at depth.

Appendix 2: Red Mountain Table 1 (JORC Code, 2012)
Set out below is Section 1 and Section 2 of Table 1 under the JORC Code, 2012 for the Red Mountain project. Data
provided by Xanadu. This Table 1 updates the JORC Table 1 disclosure dated 27 September 2022.7
1.1 JORC TABLE 1 - SECTION 1 - SAMPLING TECHNIQUES AND DATA
Criteria Commentary
Sampling
techniques dot The exploration results are based on diamond drill core samples, reverse circulation (RC)
chip samples and channel samples from surface trenches.
Drilling
techniques dot Representative one-half core samples were split from PQ, HQ & NQ diameter diamond drill core
Drill sample on site using rock saws, on a routine two metre sample interval that also honours
recovery lithological/intrusive contacts.
Logging dot The orientation of the cut line is controlled using the core orientation line ensuring uniformity
of core splitting wherever the core has been successfully oriented.
dot Sample intervals are defined and subsequently checked by geologists, and sample tags are
attached (stapled) to the plastic core trays for every sample interval.
dot RC chip samples are one-fourth splits from 1m intervals using a 75%:25% riffle splitter to obtain a
3kg sample.
dot RC samples are uniform 2m samples formed from the combination of two one-fourth split 1m
samples.
dot Trench samples are collected as 2m composite from 30m above the trench toe.
dot Sampling generally honours lithological contacts.
dot Trench samples are continuous along the length of the trench
dot The exploration results are based upon diamond drilling of PQ, HQ and NQ diameters with
both standard and triple tube core recovery configurations, RC drilling and surface trenching
with channel sampling.
dot All drill core drilled by Xanadu has been oriented using the "Reflex Ace" tool.
dot Diamond drill core recoveries were assessed using the standard industry (best) practice
which involves removing the core from core trays; reassembling multiple core runs in a v-
rail; measuring core lengths with a tape measure, assessing recovery against core block
depth measurements and recording any measured core loss for each core run.
dot Diamond core recoveries average 97% through mineralisation.
dot Overall, core quality is good, with minimal core loss. Where there is localised faulting and or
fracturing core recoveries decrease, however, this is a very small percentage of the
mineralised intersections.
dot RC recoveries are measured using whole weight of each 1m intercept measured before
splitting
dot Analysis of recovery results vs grade shows no significant trends that might indicate
sampling bias introduced by variable recovery in fault/fracture zones.
dot All drill core is geologically logged by well-trained geologists using a modified "Anaconda-
style" logging system methodology. The Anaconda method of logging and mapping is
specifically designed for porphyry Cu-Au mineral systems.
dot Logging of lithology, alteration and mineralogy is intrinsically qualitative in nature. However,
the logging is subsequently supported by 4 Acid ICP-MS (48 element) geochemistry and

The minimum allowed sample length is 30cm.
dot Core is appropriately split (onsite) using diamond core saws with the cut line routinely
located relative to the core orientation line (where present) to provide consistency of sample
split selection.
dot The diamond saws are regularly flushed with water to minimize potential contamination.
dot A field duplicate one-fourth core sample is collected every 30th sample to ensure the "representivity
of the in-situ material collected". The performance of these field duplicates is routinely
analysed as part of Xanadu's sample QC process.
dot Routine sample preparation and analyses of DDH samples were carried out by ALS
Mongolia LLC (ALS Mongolia), who operates an independent sample preparation and
analytical laboratory in Ulaanbaatar.
dot All samples were prepared to meet standard quality control procedures as follows: Crushed
to 75% passing 2mm, split to 1kg, pulverised to 85% passing 200 mesh (75 microns) and
split to 150g sample pulp.
dot ALS Mongolia Geochemistry labs quality management system is certified to ISO 9001:2008.
dot The sample support (sub-sample mass and comminution) is appropriate for the grainsize
and Cu-Au distribution of the porphyry Cu-Au mineralization and associated host rocks.
dot Trench samples by previous explorers between 2001 to 2007 were prepared and assayed
by SGS Mongolia.
dot All XAM samples were routinely assayed by ALS Mongolia for gold.
dot Au is determined using a 25g fire assay fusion, cupelled to obtain a bead, and digested with
Aqua Regia, followed by an atomic absorption spectroscopy (AAS) finish, with a lower
detection limit (LDL) of 0.01 ppm.
dot All samples were also submitted to ALS Mongolia for the 48-element package ME-ICP61
using a four-acid digest (considered to be an effective total digest for the elements relevant
to the MRE). Where copper is over-range (>1% Cu), it is analysed by a second analytical
technique (Cu-OG62), which has a higher upper detection limit (UDL) of 5% copper.
dot Quality assurance has been managed by insertion of appropriate Standards (1:30 samples
- suitable Ore Research Pty Ltd certified standards), Blanks (1:30 samples), Duplicates (1:30

dot Assay results outside the optimal range for methods were re-analysed by appropriate
methods.
dot Ore Research Pty Ltd certified copper and gold standards have been implemented as a part
of QC procedures, as well as coarse and pulp blanks, and certified matrix matched copper-
gold standards.

dot Diamond drill holes have been surveyed with a differential global positioning system (DGPS)
to within 10cm accuracy.
dot The grid system used for the project is UTM WGS-84 Zone 49N
dot Historically, Eastman Kodak and Flexit electronic multi-shot downhole survey tools have
been used at Red Mountain to collect down hole azimuth and inclination information for the
majority of the diamond drill holes. Single shots were typically taken every 30m to 50m
during the drilling process, and a multi-shot survey with readings every 3-5m are conducted
at the completion of the drill hole. As these tools rely on the earth's magnetic field to measure
azimuth, there is some localised interference/inaccuracy introduced by the presence of
magnetite in some parts of the Red Mountain mineral system. The extent of this interference
cannot be quantified on a reading-by-reading basis.
dot More recently (since September 2017), a north-seeking gyro has been employed by the
drilling crews on site (rented and operated by the drilling contractor), providing accurate
downhole orientation measurements unaffected by magnetic effects. Xanadu have a
permanent calibration station setup for the gyro tool, which is routinely calibrated every 2
weeks (calibration records are maintained and were sighted).
dot The project DTM is based on 1 m contours from satellite imagery with an accuracy of plus or minus0.1
m.
dot Trenching locations for trenches between 2001 and 2007 were located using a handheld
GPS.
dot Holes spacings range from <50m spacings within the core of mineralisation to +500m
spacings for exploration drilling. Hole spacings can be determined using the sections and
drill plans provided.
dot Holes range from vertical to an inclination of -60 degrees depending on the attitude of the
target and the drilling method.
dot The data spacing and distribution is sufficient to establish anomalism and targeting for
porphyry Cu-Au, tourmaline breccia and epithermal target types.

contained gold significant, and similar gold-rich porphyry deposits.
Drill hole dot Diamond drill holes are the principal source of geological and grade data for the Project.
Information dot See figures in this ASX/TSX Announcement.
Data dot A nominal cut-off of 0.1% CuEq is used in copper dominant systems for identification of
Aggregation potentially significant intercepts for reporting purposes. Higher grade cut-offs are 0.3%,
methods 0.6% and 1% CuEq.
dot A nominal cut-off of 0.1g/t AuEq is used in gold dominant systems like for identification of
potentially significant intercepts for reporting purposes. Higher grade cut-offs are 0.3g/t,
0.6g/t and 1g/t AuEq.
dot Maximum contiguous dilution within each intercept is 9m for 0.1%, 0.3%, 0.6% and 1%
CuEq.
dot Most of the reported intercepts are shown in sufficient detail, including maxima and
subintervals, to allow the reader to make an assessment of the balance of high and low
grades in the intercept.
dot Informing samples have been composited to two metre lengths honouring the geological
domains and adjusted where necessary to ensure that no residual sample lengths have
been excluded (best fit).
dot The copper equivalent (CuEq) calculation represents the total metal value for each metal,
multiplied by the conversion factor, summed and expressed in equivalent copper
percentage with a metallurgical recovery factor applied.
dot Copper equivalent (CuEq or eCu) grade values were calculated using the following formula:
o CuEq = Cu + Au * 0.62097 * 0.8235,
dot Gold Equivalent (AuEq or eAu) grade values were calculated using the following formula:
o AuEq = Au + Cu / 0.62097 * 0.8235
dot Where: Cu = copper grade (%); Au = gold grade (g/t); 0.62097 = conversion factor (gold to
copper); 0.8235 = relative recovery of gold to copper (82.35%)
dot The copper equivalent formula was based on the following parameters (prices are in USD):
o Copper price = 3.1 $/lb (or 6834 $/t)
o Gold price = 1320 $/oz
o Copper recovery = 85%
o Gold recovery = 70%
o Relative recovery of gold to copper = 70% / 85% = 82.35%.
Relationship dot Mineralised structures are variable in orientation, and therefore drill orientations have been
between adjusted from place to place in order to allow intersection angles as close as possible to
mineralisation true widths.
on widths dot Exploration results have been reported as an interval with 'from' and 'to' stated in tables of
and intercept significant economic intercepts. Tables clearly indicate that true widths will generally be
lengths narrower than those reported.
Diagrams dot See figures in this ASX/TSX Announcement.
Balanced dot Exploration results have been reported at a range of cut-off grades, above a minimum
Reporting suitable for open pit mining, and above a minimum suitable for underground mining.
