VANCOUVER, BC / ACCESSWIRE / October 11, 2023 / Aton Resources Inc. (TSXV:AAN) ("Aton" or the "Company") is pleased to announce the completion of the reverse circulation percussion ("RC") programme drilling at its 100% owned Abu Marawat Concession ("Abu Marawat" or the "Concession"), in the Eastern Desert of Egypt, as well as the first results from the West Garida and Abu Gaharish prospects (Figure 1).

Highlights:

• 85 holes were drilled, for a total of 11,700m, during the regional exploration RC programme at the West Garida, Abu Gaharish, Semna and Zeno prospects;
• A further 628m was drilled from 3 groundwater exploration holes approximately 20km west of the Hamama project area;
• Significant flows were recorded from the groundwater exploration holes within Nubian Sandstone cover rocks, proving the concept that this unit could provide process water supplies for the planned Hamama West and Rodruin mining projects;
• Significant mineralised intersections from the Abu Gaharish prospect included 9m @ 2.10 g/t Au, 3m @ 4.61 g/t Au and 3m @ 3.27 g/t Au. The gold mineralisation was primarily concentrated in a broadly mineralised envelope at the Gaharish Main Zone;
• Narrow mineralised intersections at West Garida included 2m @ 3.66 g/t Au and 24.3 g/t Ag from Vein #1 and 1m @ 4.00 g/t Au from Vein #3.

"We are pleased to announce the successful completion of the regional RC exploration drilling programme at Abu Marawat, and to provide the first tranche of results" said Tonno Vahk, Interim CEO. "We are particularly happy with the results of the groundwater drilling in the Nubian Sandstone west of Hamama, designed to test the potential of these rocks to provide process water supplies to the planned starter heap leach mining project at Hamama West. The results were very encouraging with the drilling intersecting significant groundwater hosted in the Nubian cover. It is particularly encouraging that the drilling did not penetrate deep enough to intersect the main target, the basal Tarif Sandstone Unit of the Nubian, which suggests that this unit may host significant groundwater resources closer to Hamama than was previously anticipated. EMRA continue to review our submission to them detailing Commercial Discoveries at the Hamama West and Rodruin deposits, in accordance with the terms of the Abu Marawat Concession Agreement, and we are hopeful that this process is moving towards a successful conclusion and the issuance of the mining licence at Abu Marawat. The issuance of the first gold mining licence in Egypt to a publicly listed foreign investor since Sukari in 2005 would represent a very significant step forwards for Aton, as well as for Egypt, the Ministry of Petroleum and EMRA."

The exploration RC drilling, undertaken by Geodrill's Egyptian branch, Geodrill for Leasing and Specialized Services Freezone LLC, commenced at the West Garida prospect, 3km east of Hamama West. Prior to the rig being mobilised to Abu Gaharish, 3 groundwater exploration holes were also drilled to test the Nubian Sandstone aquifer approximately 20km west of the Hamama project. Drilling at Abu Gaharish, and subsequently at the Semna and Zeno prospects was supported by fly camps. The drill metres for the programme are summarised in Table 1.

Groundwater exploration drilling

2 holes HAW-01 and HAW-02 were drilled south of the Hamama access road approximately 20km west of the Hamama West mineral deposit to test the potential of the Nubian Sandstone Formation to produce sufficient volumes of process water for the proposed Hamama West. Hole HAW-03 was drilled approximately 4km further east of HAW-01, back towards Hamama. Details and locations of the holes are provided in Table 2.

Table 2: Collar details of groundwater exploration drill holes

The RC holes were drilled at 53⁄4" diameter, with holes HAW-02 and HAW-03 reducing to 51⁄2" diameter. Holes HAW-01 and HAW-02 were cased through the surface alluvial sheet wash deposits to 12m depth, and HAW-03 was cased to 30m depth.

Hole HAW-01 failed to intersect any water by its target depth of 100m, and was terminated. Holes HAW-02 and HAW-03 both intersected significant groundwater from about 120m depth, with the drillers unable to keep the holes and samples dry (Figure 2). Hole HAW-02 was terminated at 294m, and HAW-03 was terminated at 234m, due to the hole collapsing in water-bearing sandstones.

All holes were drilled through a variegated sequence of predominantly brown, red, grey and black shales and mudstones, with intercalated sandstone units interpreted as belonging to the Quseir Unit of the Cretaceous Nubian Sandstone Formation. The target basal Tarif Sandstone Unit of the Nubian Sandstone Formation was not intersected in any of the 3 holes.

22 drill holes, GHP-001 to GHP-022, were completed at the Abu Gaharish prospect (Figure 1), for a total of 3,300m metres (Table 5 and Figure 4) in this first pass programme. Holes were drilled over a broad area covering c. 1.7km of strike length of mineralisation that roughly parallels the contact of the Gaharish alkali granite pluton with the surrounding metasedimentary and metavolcanic package of country rocks. 11 holes were drilled at the Gaharish Main Zone, which was the main focus of ancient and recent artisanal mine workings (GHP-001 to GHP-008, and GHP-015 to GHP-017), 3 holes were drilled to test shear structures located within country rock package (GHP-009 to GHP-011), 3 holes were drilled to test a possible stockwork and sheeted vein zone southwest of the Main Zone, and within the Gaharish pluton itself (GHP-012 to GHP-014), 4 holes were drilled to test an ionic leach wadi sediment geochemical anomaly (GHP-018 to GHP-021), and the final hole was drilled to test the North East Extension ("NEX") Vein structure, along strike and north-northeast of the Main Zone (GHP-022). The collar locations of all the drill holes are shown in Figure 4.

All mineralised intercepts from the Abu Gaharish drilling are provided in Appendix B, with significant intersections shown in Table 6. The drilling identified a broad mineralised envelope over a c. 350m strike length associated with the Main Zone, containing higher grade structures, which returned intercepts including 2m @ 8.16 g/t Au and 3m @ 4.61 g/t Au. Screen fire assay of a single 1m sample indicated the presence of coarse gold in these zones. Narrow lower grade intercepts were returned from the southern shear structures in the country rocks, and a broad low grade interval in hole GHP-012 indicated the potential for sheeted vein style reduced intrusion-related gold ("RIRG") style mineralisation to the southwest of the Main Zone.

The RC holes were drilled at 53⁄4" or 51⁄2" diameter, and the bulk percussion chip samples were collected directly into pre-written large plastic bags from the cyclone every metre, numbered with the hole number and hole depths, and laid out sequentially at the drill site. Between each metre of drilling the cyclone and top box were cleaned out with compressed air. The bags were logged on the drill sites by Aton geologists. The bulk 1m samples were weighed, and subsequently riffle split through a 3-tier splitter onsite by Aton field staff to produce an approximately 1/8 split, which was collected in cloth bags, numbered and tagged with the hole number and depth. The splitter was cleaned with compressed air between each sample. The reject material from this initial bulk split was re-bagged, labelled and tagged, and retained on the drill sites. A representative sample of each metre was washed and stored in marked plastic chip trays, each containing 20m of samples, photographed, and retained onsite as a permanent record of the drill hole.

The 1m split samples, weighing approximately 5kg each were then transported to the Rodruin sample processing facility, where they were 1/2 riffle split into 2 separate sub-samples, weighing approximately 2.5kg. One of these sub-samples was marked and labelled, and retained at the laboratory for storage. The second 1m sub-samples were then combined into 4m composite samples, weighing approximately 10kg. These were thoroughly mixed and again riffle split to produce nominal c. 250-500g 4m composite samples which were dispatched to ALS Minerals for analysis. Again the splitter was cleaned with compressed air between each sample. The 4m composite samples were allocated new sample numbers. The bulk reject material from the riffle split 4m composite samples was disposed of. QAQC samples were inserted into the 4m composite sample stream at a rate of approximately 1 certified reference material (or "standard" sample) every 60 samples, 1 blank sample every 30 samples, and 1 field duplicate split sample every 30 samples.

The 4m composite 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. 50g size, which was shipped on to ALS Minerals at Rosia Montana, Romania for analysis. The 4m composite samples were analysed for gold by fire assay with an atomic absorption spectroscopy ("AAS") finish (analytical code Au-AA23. Any high grade samples (Au >10 g/t) were re-analysed using analytical code Au-GRA21 (also fire assay, with a gravimetric finish).

Upon receipt of the final 4m composite assay results from ALS, a number of the retained 1m sub-samples were selected by a senior Aton geologist for re-assaying, corresponding to 4m composite assays deemed to be of significance. The selected 1m sub-samples were again riffle split to produce nominal c. 250-500g 1m split samples which were again allocated new sample numbers. These were dispatched to ALS Minerals for the same sample preparation at Marsa Alam, and for subsequent analysis at Rosia Montana. The bulk reject material from the 1m sub-sample splits was re-bagged and retained onsite for storage at Rodruin. QAQC samples were inserted into the 1m split sample stream at a rate of approximately 1 standard every 30 samples, 1 blank sample every 15 samples, and 1 field duplicate split sample every 15 samples.

The 1m split samples were again analysed for gold by fire assay (analytical code Au-AA23), and for silver, copper, lead and zinc using an aqua regia digest followed by an AAS finish (analytical code AA45). Any high grade gold samples (Au >10 g/t) were again re-analysed using analytical code Au-GRA21 (also fire assay, with a gravimetric finish). Any high grade Ag and base metal samples (Ag >100 g/t, and Cu, Pb and Zn >10,000ppm or >1%) were re-analysed using the ore grade technique AA46 (also an aqua regia digest followed by an AAS finish).

All intersections herein reported relate to 1m split samples.
