Vancouver, British Columbia, July 9 , 2025: Aton R esources Inc. (AAN: TSX -V) (“Aton” or the “Company")
updates investors on the results of its diamond drilling programme at the Abu Marawat deposit (“Abu
Marawat”), located within the retained exploration areas of the Company’s Abu Marawat Concession (the
“Concession”) in the Eastern Desert of Egypt.
Highlights:
• The diamond drilling programme at Abu Marawat has now been completed, with 113 holes drilled for
a total of 9,642.7 metres. During the programme holes were predominantly drilled horizontally or at
shallow angles to test near-surface mineralisation in an area of steep and mountainous terrain that is
hard to access for conventional drilling rigs, and is largely undrilled;
• Results for a further 29 holes, AMD-167 to AMD-195, are now available, with significant high grade
polymetallic mineralised intersections including:
• 33.86 g/t Au, 419 g/t Ag, 38.51 g/t AuEq, 0.56% Cu and 6.51% Zn over a 2.50m interval from
the Fin Vein, from 151.80m downhole depth (hole AMD-190);
• 44.59 g/t Au, 103 g/t Ag, 45.73 g/t AuEq, 0.10% Cu and 0.21% Zn over a 1.60m interval from
the J Vein, from 10.40m downhole depth (hole AMD-191);
• 5.77 g/t Au, 96.7 g/t Ag, 6.85 g/t AuEq, 2.20% Cu and 0.96% Zn over a 6.10m interval from the
CVZ, from 54.90m downhole depth (hole AMD-181);
• 6.00 g/t Au, 252 g/t Ag, 8.81 g/t AuEq, 0.23% Cu and 1.61% Zn over a 4.70m interval from the
Fin Vein, from 159.50m downhole depth (hole AMD-192);
• 7.32 g/t Au, 42.9 g/t Ag, 7.80 g/t AuEq, 0.42% Cu and 3.63% Zn over a 4.90m interval from the
Fin Vein, from 9.00m downhole depth (hole AMD-170); and
• 4.50 g/t Au, 58.9 g/t Ag, 5.15 g/t AuEq, 0.67% Cu and 3.81% Zn over a 6.00m interval from the
Fin Vein, from 4.10m downhole depth (hole AMD-178).
“I am very pleased to be able to announce another set of really strong drill results, this time from the Abu
Marawat deposit. Along with the results we released from Semna last week these latest results again
demonstrate the presence of high grade mineralisation at the Abu Marawat Concession , and its undoubted
potential to support multiple gold mining operations ” said Tonno Vahk, CEO. “We are currently focussing on
Abu Marawat and Semna, as we look to bring then into the Hamama PFS, but in the coming months we are
planning to kick off maiden drill programmes at some of our other highly prospective target areas including the
second early 20 th Century gold mine on the concession at Sir Bakis, and the Bohlog prospect where we
trenched wide zones of surface mineralisation back in 2017. At Hamama it is all systems go where we have
both the RC and diamond drill r igs turning on geotechnical and metallurgical sampling drill programmes, as
we continue to drive the PFS forwards, and we are expecting drilling to resume again at Abu Marawat within
the next 2 weeks, following on from this latest set of great results. Aton will also be at the Egypt Mining Forum
in Cairo on 15-16 July, and we are very much looking forward to meeting and talking to some of you there!”
Abu Marawat gold-silver-copper-zinc deposit
The Abu Marawat gold-silver-copper-zinc deposit is located approximately 35km northeast of the Hamama
West deposit and 10km north-northeast of the Semna gold mine project, and is accessed via a well maintained
desert track from the Qena-Safaga highway, approximately 25km to the north (Figure 1). On March 1, 2012
Aton Resources, when formerly named Alexander Nubia International Inc , announced a maiden Inferred
Mineral R esource at Abu Marawat, prepared by Roscoe Postle Associates Inc. , in compliance with the
requirements set out in Canada’s National Instrument 43 ‐101. The resource was subsequently restated in an
updated Technical Report without amendment (see news release dated January 24 , 201 7), and which is
available online at Aton’s website at https://atonresources.com/investors/reports-and-presentations. This
Inferred Mineral Resource was based on 98 diamond drill holes totalling 19,573 metres. 19 of these holes were
drilled by a former property owner, Minex Minerals Egypt, a wholly owned subsidiary of Greenwich Resources
Plc during the late 1980’s, and the remainder were drilled by Aton in 2011. The Inferred Mineral Resource
comprises 2.9 million tonnes at an average grade of 1.75 g/t Au, 29.3 g/t Ag, 0.77% Cu and 1.15% Zn ,
containing 162 thousand ounces of gold, 2.7 million ounces of silver, 49 million lbs of copper, and 73 million
lbs of zinc, and was based on net smelter return (“NSR”) cut‐off grades.
Figure 1: Geology plan of the Abu Marawat Concession, showing the location of the Abu Marawat deposit
The polymetallic mineralisation at Abu Marawat is interpreted as being mesothermal in origin, and occurs in a
series of discrete and roughly parallel N-S to NNW-SSE trending veins and structures, of which the Fin Vein
and the CVZ are the most significant, hosted within a sequence of intensely hydrothermally altered, felsic
metavolcanic rocks (Figure 2). The Fin Vein and the CVZ are about 50-100m apart and have been traced for
at least 800m in surface outcrop and drill holes. Aton’s previous drilling has demonstrated that these structures
extend to at least 200m in depth. The bulk of the Inferred Mineral Resource at the Abu Marawat deposit
encompasses parts of the CVZ and the Fin Vein, but there are also other subparallel mineralised veins to the
east and to the west of the se structures, such as the J Vein, the JVZ structure, and the Valley Vein zone
(Figure 2).
Figure 2: Geology plan of the Abu Marawat area, showing the location of Aton drill holes
The mineralisation at Abu Marawat comprises a series of steep to near vertical finely brecciated quartz-
carbonate-sulphide “veins”. At surface the Fin Vein and the Central Vein zone (“CVZ”) are expressed by quartz-
rich gossans, and all the larger structures display development of intense wallrock alteration in outcrop. Several
of the veins, notably the CVZ, were mined at surface in ancient times, apparently primarily for copper. The
mineralised system at Abu Marawat currently remains open both laterally and at depth.
Further to the north, the Abu Marawat deposit appears to be truncated by a large W NW-ESE trending fault
postulated to run beneath wadi sediments. To the east a prominent ridge composed of altered ultramafic rocks
is thought to represent a significant geological terrane boundary (Figure 2).

Abu Marawat diamond drilling programme
The diamond drill programme started in June 2024, and has now been completed with 113 holes (holes AMD-
101 to AMD-213) drilled for a total of 9,642.7 metres. During the programme holes have predominantly been
drilled horizontally or at shallow angles to test previously undrilled near-surface mineralisation.
Assay results are now available for a further 2 9 holes, AMD-167 to AMD-195, and the collar details of these
holes are provided in Appendix A. The holes were predominantly designed to test the Fin Vein, with some also
veins testing the CVZ, as well as other subsidiary structures including the V Ridge Vein, the J Vein and the
JVZ and JVZ West structures.

Table 1: Selected intersections from the Abu Marawat diamond drilling programme, AMD-167 to AMD-195
Significant high grade gold -silver-copper-zinc mineralisation was consistently intersected in the currently
reporting tranche of drill holes, over mineable widths of about 2-6 metres from the Fin Vein. These mineralised
intervals include 33.86 g/t Au, 419 g/t Ag, 38.51 g/t gold equivalent (“AuEq”, calculated using Au and Ag
only, with a Au:Ag ratio of 90), 0.56% Cu and 6.51% Zn over a 2.50m interval, from 151.80m downhole depth
(hole AMD-190); 6.00 g/t Au, 252 g/t Ag, 8.81 g/t AuEq, 0.23% Cu and 1.61% Zn over a 4.70m interval,
from 159.50m downhole depth (hole AMD-192); 7.32 g/t Au, 42.9 g/t Ag, 7.80 g/t AuEq, 0.42% Cu and 3.62%
Zn over a 4.90m interval , from 9.00m downhole depth (hole AMD -170); and 4.50 g/t Au, 58.9 g/t Ag, 5.15
g/t AuEq, 0.67% Cu and 3.81% Zn over a 6.00m interval, from 4.10m downhole depth (hole AMD-178).
All these intersections occur within the oxidised and weathered upper part of the F in Vein, which appears to
be replacive in origin. The Fin Vein mineralisation extends to the surface, and in outcrop it stands up as distinct
positive topographic feature . It typically displays a granular or brecciated quartz fabric, with a saccharoidal,
and honeycombed or vuggy texture when weathered, caused by the removal of granular carbonate minerals
and the oxidation of sulphides . It is primarily composed of quartz, carbonates, and iron oxides, as well as
copper, zinc and lead oxide mineral species in the weathered zone. See news release dated November 7,
2024 for more details about the Fin Vein.
Mineralisation was also intersected in many of the holes from some of the subsidiary structures, including the
V Ridge Vein, the J Vein , and the JVZ and JVZ West structures (Figure 3). The mineralisation was usually
sporadic and often occurred in narrow zones, but the J Vein did return a single very high grade mineralised
interval of 44.59 g/t Au, 103 g/t Ag and 45.73 g/t gold equivalent over 1.60m, from 10.40m downhole depth
(hole AMD-191).
Sampling and analytical procedures
The Abu Marawat diamond drill holes were drilled at a combination of either HQ3 size (61.1mm diameter)
and/or PQ3 size (83mm diameter). Core was loaded into metal core boxes by the drill crew under supervision
of Aton geologists. The core was metre marked onsite at the Abu Marawat camp , with basic geotechnical
measurements (total core recovery, solid core recovery, and rock quality designation) undertaken by Aton
geologists, as well as specific gravity measurements . It was also photographed in both wet and dry states at
Abu Marawat. The core was then carefully packed and transported to the Rodruin exploration camp, where it
was geologically logged by senior Aton geologists, and marked up for cutting and sampling at the Rodruin core
farm. Samples were typically selected over nominal 1m intervals, but as determined by the logged lithologies.
The core was half-cut by Aton staff at the onsite Rodruin sample preparation facility. After the core had been
cut, the relevant cut intervals were then photographed again.
The split half-core samples were collected and bagged up in cloth bags, weighed and crushed to -4mm onsite,
and split to a nominal c. 500-1,000g sample size. The coarse crushed reject samples are retained onsite at
the Rodruin sample preparation facility.
QAQC samples were inserted into the sample runs at a rate of approximately 1 certified reference material (or
“standard” sample) every 30 samples, 1 blank sample every 15 samples, and 1 duplicate split sample every
15 samples.
The dried, crushed and split samples were shipped to ALS Minerals sample preparation laboratory at Marsa
Alam, Egypt, where they were pulverised to a size fraction of better than 85% passing 75 microns. From this
pulverised material a further sub -sample was split off with a nominal c. 100g size, which was shipped on to
ALS Minerals at Rosia Montana, Romania for geochemical analysis. The reject pulp material was returned to
the sample preparation facility at Rodruin, where it is also retained onsite
The samples were analysed for gold by fire assay (30g charge) with an atomic absorption spectroscopy (“AAS”)
finish (analytical code Au-AA23). Any high grade gold samples (>10 g/t Au) were re-analysed using analytical
code Au-GRA22 (also fire assay, 50g charge, with a gravimetric finish).
Samples were also analysed for silver , copper, lead and zinc using an aqua regia digest followed by an AAS
finish (analytical code AA45). Any high grade silver and base metal samples (Ag >100 g/t, and Cu , Pb or Zn
>10,000ppm or >1%) were re -analysed using the ore grade technique AA46 (also an aqua regia digest
followed by an AAS finish).
About Aton Resources Inc.
Aton Resources Inc. (AAN: TSX-V) is focused on its 100% owned Abu Marawat Concession (“the Concession”), located
in Egypt’s Arabian -Nubian Shield, approximately 200 km north of AngloGold Ashanti’s world-class Sukari gold mine.
Aton has identified numerous gold and base metal exploration targets at the Concession, including the Hamama deposit
in the west, the Abu Marawat deposit in the northeast, and the Rodruin deposit in the south of the Concession. Two
historic British gold mines are also located on the Concession at Semna and Sir Bakis. Aton has identified several
distinct geological trends within the Concession, which display potential for the development of a variety of styles of
precious and base metal mineralisation. The Abu Marawat exploitation lease is 57.66 km2 in size, covering the Hamama
West and Rodruin mineral deposits, and was established In January 2024 and is valid for an initial period of 20 years.
The Concession also includes an additional 255.0 km2 of exploration areas, retained for a further period of 4 years from
January 2024. The Concession is located in an area of excellent infrastructure; a four -lane highway, a 220kV power
line, and a water pipeline are in close proximity, as are the international airports at Hurghada and Luxor.
