ATEX INTERSECTS 0.70% CUEQ OVER 964M IN A 200M STEP-OUT ALONG THE RECENTLY DISCOVERED HIGH-GRADE WESTERN PORPHYRY TREND

Atex Resources Inc. has released complete assay results for drill holes ATXD-22A and ATXD-23 from its phase III drill campaign at the Valeriano copper-gold project located in Atacama region, Chile.

Highlights include:

• ATXD-23 successfully extended the high-grade trend discovered in ATXD-11B, intersecting 964 metres of 0.70 per cent copper equivalent (CuEq) (0.48 per cent Cu, 0.24 gram per tonne Au and 78 parts per million Mo (molybdenum)) starting at 782 metres and including:
  • 602 metres of 0.80 per cent CuEq (0.50 per cent Cu, 0.37 g/t Au and 11 ppm Mo) from 1,130 metres;
  • 120 metres of 0.90 per cent CuEq (0.45 per cent Cu, 0.54 g/t Au and three ppm Mo) starting at 1,612 metres;
  • Additionally, ATXD-23 intersected 192 metres of 0.56 per cent CuEq (0.24 per cent Cu, 0.40 Au and four ppm Mo) from 1,858 metres to the bottom of the hole, ending in mineralization;
  • The newly discovered Western porphyry trend now has a strike length of approximately 700 metres and remains open. The phase IV program will include holes testing further extensions of this high-grade discovery.
• ATXD-22A (daughter hole), targeting the Eastern porphyry trend, intersected 546 metres of 0.45 per cent CuEq (0.32 per cent Cu, 0.08 g/t Au and 173 ppm Mo) from 921.4 metres down hole.
  • This mineralization continues from hole ATXD-22 (mother hole) grading 0.44 per cent CuEq over 292 metres from 630 to 922 metres (0.31 per cent Cu, 0.01 g/t Au and 108 ppm Mo) (see March 30 release) above the kick-off point for ATXD-22A.
• The final two holes of the program, ATXD-24 and ATXD-22B, reached depths of 1,842.4 metres and 1,615.05 metres, respectively, with ATXD-24 paused in early porphyry within the Central trend and ATXD-22B in potassic altered, mineralized rock milled breccia (RMB) approaching the Central trend extension.
  • Both holes were paused due to earlier-than-expected adverse weather conditions;
  • Samples for the partial holes ATXD-24 and ATXD-22B have been sent to the lab with results expected by late June or early July.

"We are incredibly happy and proud of how well our team and partners were able to execute throughout this campaign," stated Raymond Jannas, president and chief executive officer of Atex. "The phase III program has delivered on, and exceeded, its stated objectives, expanding the mineralized footprint, confirming continuity along the Central high-grade trend and testing new targets. This has led to the discovery of a new high-grade porphyry trend, the Western trend, where ATXD-11B, the highest-grade hole of the phase III, was drilled. The overall size of the system has grown to 1,000 metres long by 1,000 metres wide with a vertical extent of 1,000 metres. Within this footprint we have confirmed two high-grade porphyry trends and have demonstrated their continuity with multiple drill intersections in both. We are looking forward to completing a full review of these results and integrating them into our plans for phase IV, where we intend to continue demonstrating the enormous potential of the Valeriano porphyry system. We are also working towards an updated mineral resource estimate incorporating drilling up to and including phase III. We expect to update investors on this in the coming months."

Results

The intervals reported in ATXD-23 are interrupted by a 112-metre interval of intermineral porphyry (IMP) from 1,746 to 1,858 metres down hole. This interval of IMP grades 0.24 per cent CuEq (0.11 per cent Cu, 0.16 g/t Au and two ppm Mo). ATXD-23 was drilled at a subvertical angle (minus 83 degrees) and drilled along the intermineral porphyry before exiting back into the early porphyry. Phase IV drill plans for the Western trend will include drill holes with intersection angles planned to drill across the target geology and better test the width of the trend.

ATXD-22A (daughter hole) commenced at a depth of 921.4 metres and was drilled southeast to test the northern extension of the Eastern trend. It was targeted to intersect this trend approximately 400 metres north of VAL-16 (1,045 metres of 0.54 per cent CuEq (0.39 per cent Cu, 0.17 g/t Au and 54 ppm Mo)). The hole commenced in mineralized RMB from its start point at 921 metres down hole in ATXD-22. Mineralization and alteration in the hole decreased as the hole intersected a series of faults that ultimately cut-off mineralization.

ATXD-24 was drilled to the southeast across the eastern contact of the Western trend and toward the Central trend. The hole intersected chalcopyrite-bearing, mineralized RMB and a series of intermineral porphyries starting from a depth of 580 metres to a depth of 1,350 metres. Several chalcopyrite-bearing hydrothermal breccia units were observed from 1,350 metres to 1,525 metres down hole. Strong potassic alteration with intense stockwork and veining was intersected within the early porphyry from 1,525 metres to where the hole was paused at 1,842.4 metres. Assay results from ATXD-24 are expected in late June or early July.

ATXD-22B (daughter hole), targeting the Central high-grade trend extension, commenced at a depth of 444 metres down hole from ATXD-22 (mother hole). The hole intersected chalcopyrite-bearing argillic altered RMB from 595 metres to a depth of 1,100 metres. From 1,100 metres, to where the hole was paused due to weather conditions, potassic altered chalcopyrite-bearing RMB was intersected, including zones of veining with visible chalcopyrite and bornite mineralization. The hole has been left in a condition to be re-entered and completed, as an option in phase IV, and results are expected by late June or early July.

The phase III campaign commenced in October, 2022, and has been completed in late May, 2023. In total 12,513 metres of drilling were completed in eight drill holes, including four holes from surface and four daughter holes drilled from existing holes. There are two holes still to be reported from phase III, ATXD-24 and ATXD-22B, which are expected to be announced in late June or early July.

Phase III achieved a series of execution records for the project, including completing the deepest hole to date at a depth of 2,190.5 metres (ATXD-11B) as well as achieving a 100-per-cent completion rate on drill holes. Additionally, the utilization of directional drilling in phase III resulted in a saving of approximately 3,000 metres of drilling from surface. Phase IV, which will follow up on the success achieved in phase III, is expected to commence in October, 2023.

Outlook

Final assay results for the remaining holes of the phase III drill program are expected by the end of June or early July. The company intends to use these phase III results and data to update the copper-gold mineral resource statement for the Valeriano project and file an updated National Instrument 43 101 compliant technical report. Additionally, metallurgical test work using core from the phase III program is being undertaken by Atex in conjunction with Libertas Metallurgy and Base Met Labs of Kamloops, B.C. This work is expected to be completed in Q3.

Quality assurance/quality control

Drill holes are collared with a PQ drill bit, reduced to HQ and, sequentially, to NQ as the drill holes progressed deeper. Drill core produced by the drill rigs was extracted from the core tubes by the drill contractor under the supervision of Atex employees, marked for consistent orientation and placed in core boxes with appropriate depth markers added. Full core boxes were then sealed before being transported by Atex personnel to the Valeriano field camp. Core at the field camp is processed, quick logged, checked for recovery, photographed, and marked for specific gravity, geotechnical studies and for assays. From camp, the core is transferred to a secure core-cutting facility in Vallenar, operated by IMG, a third party consultant. Here, the core trays are weighed before being cut using a diamond saw under Atex personnel oversight. Atex geologists working at this facility double-check the selected two-metre sample intervals, placing the samples in seal bags and ensuring that the same side of the core is consistently sampled. Reference numbers are assigned to each sample and each sample is weighed. The core trays with the remaining half core are weighed and photographed. Additionally, core logs are updated, and the specific gravity and geotechnical samples are collected. The remaining core is stored in racks at the company's secure facility in Vallenar.

From Vallenar samples are sent to an ALS preparation facility in La Serena. ALS is an accredited laboratory which is independent of the company. The prepared samples were sent to the ALS assay laboratories in either Santiago, Chile, or Lima, Peru, for gold (Au-AA24), copper (Cu-AA62), molybdenum (Mo-AA62) and silver (Ag-AA62) assays as well as and multielement inductively coupled plasma (ME-MS61) analysis. No data quality problems were indicated by the QA/QC program.

About Atex Resources Inc.

Atex is exploring the Valeriano copper-gold project which is located within the emerging copper-gold porphyry mineral belt linking the prolific El Indio high-sulphidation belt to the south with the Maricunga gold porphyry belt to the north. This emerging belt, informally referred to as the Link belt, hosts several copper-gold porphyry deposits at various stages of development, including Filo del Sol (Filo Mining), Josemaria (Lundin Mining), Los Helados (NGEX Minerals/JX Nippon), La Fortuna (Teck Resources/Newmont) and El Encierro (Antofagasta/Barrick Gold).

Valeriano hosts a large copper-gold porphyry deposit overlain by a near-surface oxidized epithermal gold deposit. In 2022, Atex completed the company's first limited drill test of the copper-gold porphyry system that is now being followed up with campaign of directional drilling to extend the high-grade trend, test new targets and expand the mineralized envelope.
