Aton Reports the First Results from its Abu Marawat RC Infill Drill Programme, Including 17.13 g/t Gold, 307 g/t Silver, 0.82% Copper and 5.50% Zinc Over a 9 Metre Interval

VANCOUVER, BC / ACCESS Newswire / March 26, 2026 / Aton Resources Inc. (TSX-V:AAN) ("Aton" or the "Company") updates investors on the first results from its reverse circulation percussion ("RC") 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 results from the first 14 holes of the 2025 RC infill drilling programme at Abu Marawat, AMP-214 to AMP-227 are now available. Further significant high grade polymetallic mineralised intersections were returned from the Fin Vein, including the following:

  • 21.85 g/t Au, 178 g/t Ag, 23.83 g/t AuEq, 0.55% Cu and 5.21% Zn over a 20m interval from 31m downhole depth (hole AMP-225), estimated 5.5m true width;

  • 17.13 g/t Au, 307 g/t Ag, 20.54 g/t AuEq, 0.82% Cu and 5.50% Zn over a 9m interval from 77m downhole depth (hole AMP-218), estimated 6.5m true width;

  • 5.48 g/t Au, 60.5 g/t Ag, 6.15 g/t AuEq, 0.36% Cu and 2.07% Zn over a 14m interval from 54m downhole depth (hole AMP-216), estimated 10m true width;

  • 7.74 g/t Au, 109 g/t Ag, 8.96 g/t AuEq, 0.40% Cu and 4.07% Zn over an 8m interval from 48m downhole depth (hole AMP-223), estimated 3m true width; and

  • 7.01 g/t Au, 63.7 g/t Ag, 7.72 g/t AuEq, 0.68% Cu and 3.31% Zn over a 6m interval from 14m downhole depth (hole AMP-224), estimated 4.5m true width.

"We are pleased to release another set of very strong drill results from the Abu Marawat deposit, and are particularly pleased with the high grade polymetallic vein mineralisation we continue to intersect there. The previously reported metallurgical testwork programme has indicated that we will be able to successfully recover gold, silver, copper and zinc from the Abu Marawat mineralisation through a combination of conventional CIL, flotation and SART processing, so the continued delineation of near surface high grade polymetallic mineralisation is highly encouraging" said Tonno Vahk, Chief Executive Officer. "On other fronts we continue to push ahead with the development of the Hamama gold mine, with a new programme of metallurgical testwork currently ongoing in the UK, and we are also looking to appoint heap leach design and FEED contractors in the coming weeks, for the design and development of the Hamama West starter heap leach project. Our long-term consultants SLR Consulting and Cube Consulting are also making good progress on the updated mineral resources and mine design at Hamama, and will soon be switching their focus to updated and maiden MRE's at Abu Marawat and Semna as the final drill data becomes available, and we look forward to restating the mineral resources over the whole of the Abu Marawat Concession later this year, as we push on towards the development of Egypt's next gold mine."

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 Resource 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, 2017), 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.

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 these 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 the 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 WNW-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).

An infill RC drilling programme was completed at Abu Marawat in November 2025, with 71 holes (holes AMP-214 to AMD-284) drilled for a total of 6,647 metres. The programme was designed to infill previous diamond drilling, and to provide a sufficient drill density to allow for the estimation of an indicated resource at the Abu Marawat deposit. Assay results are now available for the first 14 holes, AMP-214 to AMP-227, which were mainly designed to test the northern part of the Fin Vein (Figure 3). The collar details of these holes are provided in Table 1 below.
