FOR IMMEDIAT E RELEASE Aton reports further diamond drilling results from Abu Marawat , including 8.52 g/t gold and 88.7 g/t silver over 15.4 metres, and 6.06 g/t gold and 59.6 g/t silver over 17.3 metres

Drill Results

FOR IMMEDIAT E RELEASE

Aton reports further diamond drilling results from Abu

Marawat , including 8.52 g/t gold and 88.7 g/t silver over 15.4

metres, and 6.06 g/t gold and 59.6 g/t silver over 17.3 metres

Vancouver, British Columbia, May 20, 2025: Aton Resources Inc. (AAN: TSX -V) (“Aton” or the “Company")

updates investors on the results of its ongoing 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:

• To date 95 diamond drill holes have been drilled at Abu Marawat, for a total of 7,917m. All holes have

been 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 21 holes, AMD-146 to AMD-166, are now available, with significant high grade

polymetallic mineralised intersections including:

• 8.52 g/t Au, 88.7 g/t Ag, 9.50 g/t AuEq, 2.15% Cu and 0.59% Zn over a 15.40m interval on the

Central Vein zone (“CVZ”), from 23.50m downhole depth (hole AMD-151);

• 6.06 g/t Au, 59.6 g/t Ag, 6.72 g/t AuEq, 1.02% Cu and 1.24% Zn over a 17.30m interval on the

CVZ, from 32.80m downhole depth (hole AMD-146);

• 4.14 g/t Au, 40.7 g/t Ag, 4.59 g/t AuEq, 0.85% Cu and 0.17% Zn over a 13.90m interval on the

CVZ, from 13.30m downhole depth (hole AMD-149);

• 3.07 g/t Au, 33.7 g/t Ag, 3.44 g/t AuEq, 0.45% Cu and 0.43% Zn over a 16.50m interval on the

CVZ, from 8.00m downhole depth (hole AMD-148).

“This latest tranche of results from the horizontal diamond drilling programme at Abu Marawat is very pleasing,

and is indicating the presence of a significant near-surface core of high grade mineralisation on the CVZ” said

Tonno Vahk, CEO. “We are also seeing some nice looking mineralisation in the ongoing RC programme at

Semna, and we expect to be able to release the first results from this programme in the coming weeks. The

programme at Abu Marawat is approaching the finish line, and we are also now doing some additional drilling

there for a metallurgical testwork programme. The identification and delineation of high grade mineralisation

near to surface at both Abu Marawat and Semna is very positive as Aton looks to the long term development

of multiple mining operations at the Abu Marawat Concession. Work on the Hamama West PF S and ESIA is

continuing steadily, with the ongoing establishment of the environmental baseline, and we are planning to start

the next phase of hydro drilling at Hamama in the coming weeks, as we seek to establish a viable groundwater

supply for the mining projects.”

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).

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 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 current diamond drill programme started in June 2024, and to date 95 diamond drill holes (holes AMD -

101 to AMD -195) have been completed, for a total of 7,917.2 metres. All the holes have been drilled

horizontally or at shallow angles to test previously undrilled near-surface mineralisation.

Assay results are now available for a further 21 holes, AMD-146 to AMD-166, and the collar details of these

holes are provided in Appendix A. The holes were predominantly designed to test the CVZ, near to the surface,

with the drilling on west -southwesterly azimuths. Some holes were extended to intersect the Fin Vein further

to the west. The drilling was focussed on the central area of the Abu Marawat deposit (Figure 2).

Holes AMD-165 and AMD-166 were also drilled on west-south westerly azimuths towards the southern end of

the CVZ.

Table 1: Selected intersections from the Abu Marawat diamond drilling programme, AMD-146 to AMD-166

This latest tranche of drill holes again returned significant polymetallic mineralised intersections from the CVZ,

in some cases carrying notably high grades of gold, silver and also copper over consistent widths . These

intersections including 8.52 g/t Au, 88.7 g/t Ag, 9.50 g/t gold equivalent (“AuEq”, calculated using Au and

Ag only, with a Au:Ag ratio of 90), 2.15% Cu and 0.59% Zn over a 15.40m interval, from 23.50m downhole

depth (hole AMD-151); 6.06 g/t Au, 59.6 g/t Ag, 6.72 g/t AuEq, 1.02% Cu and 1.24% Zn over a 17.30m

interval, from 32.80m downhole depth (hole AMD-146); and 4.14 g/t Au, 40.7 g/t Ag, 4.59 g/t AuEq, 0.85%

Cu and 0.17% Zn over a 13.90m interval, from 13.30m downhole depth (hole AMD-149). These intersection

widths effectively reflect the true width of the mineralised CVZ structure. Please refer to the news release dated

March 11, 2025 for further details about the CVZ mineralisation.

Hole AMD -165, drilled at the southern outcropping extent of the CVZ also intersected a wide zone of

mineralisation on the CVZ (0.69 g/t Au, 19.4 g/t Ag, 0.90 g/t AuEq and 0.21% Cu, over a 23.90m interval from

33.10m downhole depth), albeit at a lower grade. This phase of the drilling has indicated a continuous body of

near-surface mineralisation in excess of 250m strike length in the central part of the CVZ, with notably high

grades of gold, silver, copper and also zinc, particularly in its central core, although the grades diminish towards

the southern and northern ends of the structure. A further phase of reverse circulation percussion (“RC”) drilling

is planned to test the deeper parts of the CVZ and to infill and confirm the previous diamond drilling carried out

by Aton during 2011 and Minex during the 1980’s.

Activity Update

• The Company is continuing its discussions with its JV partners at the Egyptian Mineral Resources

Authority, and the Ministry of Petroleum and Mineral Resources, with regards to the proposed changes

to the Hamama West Pre-Feasibility Study (see news release dated November 8, 2024). The Company

intends to change the focus from the originally envisaged heap leach processing route, to a modular CIL

processing route to allow for the processing of mineralisation from Semna and Abu Marawat .

• The Company has engaged Wardell Armstrong International (“WAI”), part of the SLR Consulting Group,

to undertake a programme of metallurgical testwork on the different Abu Marawat mineralisation types.

Drilling is currently ongoing to collect whole PQ3 sized core samples at Abu Marawat for comminution

testing, as well as leach testing. Additionally further testwork will be undertaken to assess the viability of

SART (sulphidisation, acidification, recycling and thickening) processing to recover copper from the Abu

Marawat mineralisation.

• The initially planned c. 5,000 metre phase 3 RC drilling programme at the Semna deposit to follow up on

the 2023 phase 1 RC and 2024 phase 2 diamond drilling programmes, is ongoing, with 39 holes

completed for a total of 4,639 metres drilled to date. The Company expects to be able to release the first

results of this programme in the coming weeks.

• The Company plans to suspend the RC programme at Semna at the end of May 2025 and mobilise the

drill rig and crews to Hamama to carry out the next phase of hydro drilling as part of the plan to develop

a viable groundwater source for the Hamama project. RC drilling in January 2025, has confirmed that the

Nubian Sandstone aquifer has sufficient properties to yield adequate water for the Hamama West mine

project (WAI internal technical note, 17/2/2025). The next step will be the drilling, using mud rotary drilling

methods, and construction of a c. 300-350m deep monitoring well in June 2025. After this has been

completed a 300mm diameter pump test well will be drilled, and it is planned to construct this for future

use as a production well.

• Environmental monitoring programmes for the Hamama West Environmental and Social Impact

Assessment, also being undertaken by WAI, are ongoing at Hamama West . A weather station was

installed at Hamama in November 2024, and air quality and dust monitoring equipment have since been

installed.

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 prepa ration 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-GRA21 (also fire assay, 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 C oncession 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.
