Montreal, Quebec--(Newsfile Corp. - September 5, 2024) - Amex Exploration Inc. (TSXV: AMX) (FSE: MX0) (OTCQX: AMXEF) ("Amex" or the "Company") is pleased to announce that it has completed a Mineral Resource Estimate ("MRE") on the company's flagship Perron Project in the northwestern Abitibi region of Quebec. The majority of ounces come from the Company's High-Grade Zone ("HGZ"), with important contributions from the Denise Zone ("Denise"), the Gratien Zone ("Gratien"), the Grey Cat Zone ("Grey Cat") and the Team Zone ("Team"). The drillhole database for the resource was closed on June 30, 2024, meaning recent drilling has not been included in this resource iteration at Perron. All zones on the property remain open in multiple directions for further expansion and Amex's current continuing drill program is fully funded until the conclusion of 2025.

See Figure 1 for the location of the Perron Project, Figure 2 for a plan view of mineral resources at the Perron Project, Figure 3 for a sectional view of mineral resources of the Perron Project, and Table 1 for a summary of total mineral resources, Table 2 for summary of total mineral resources by zone and Table 3 for parameters used to constrain resources at Perron.

Amex will be hosting a webinar today with Victor Cantore, CEO and Aaron Stone, VP Exploration at 1:00pm EDT to discuss the MRE in more detail. Please register here:

MRE Highlights:

• Open pit and underground stope constrained 594,100 of measured and indicated ounces at 4.28 g/t Au and 1,049,650 of inferred ounces at 3.80 g/t Au.
• The MRE shows excellent continuity throughout the project with exceptional high grade throughout, specifically in the High-Grade Zone (HGZ) which alone hosts 336,170 of measured and indicated ounces at 12.05 g/t Au and 415,470 of inferred ounces at 10.49 g/t Au.
• Of important significance within the HGZ is with improved confidence, comes increased grade. With regard to the HGZ under Table 2, as drill spacing is tightened to upgrade resources from inferred to indicated to measured, the grade improves. This is rare in the gold industry and speaks to exceptional continuity of the zone.
• The MRE is a base case for the gold at Perron and includes drilling up to June 30, 2024. Approximately 600,000 m of accumulative fully funded drilling is expected to be completed by the end of 2025.
• All zones remain open at Perron, providing excellent future mineral resource expansion potential.
• Metallurgical test work by SGS Canada achieved an overall gold recovery of up to 99% in the HGZ and up to 95% in the Denise, Team, Gratien and Grey Cat Zones.
• Near by housing, roads, electricity and labour are expected to favourably impact the economics of the Perron project in the upcoming PEA expected later this year.
• The Perron project also hosts VMS (copper-zinc) mineralization which has not been included in today's MRE nor any of the silver credits that exist in some zones of the property. The Company plans to complete the modelling requirements surrounding these additional metals in the future, which is expected to enhance the economics of the project.

Jacques Trottier, PhD, Executive Chairman of Amex Exploration, commented, "I am very proud of our progress to date. Throughout my time at Perron, I was convinced that the project hosted a significant high-grade gold resource, so it is fantastic to have realised this. In my opinion, the high-grade nature of Perron is what truly sets its apart from its peers and we have just begun to scratch the surface of the potential. The grade at Perron compares very favourably to many of the recent world class projects in Canada and elsewhere. There is significant room for this resource to grow, as much of the property is yet to be explored. New machine learning and AI techniques have generated new high priority targets for us, some of which we have begun to test with success. Given the projects quality high-grade ounces, proximity to infrastructure and workforce, we look forward to releasing our project economics in the PEA, which remains on track for Q4 of this year. It should also be noted that this resource is purely gold focused. None of the silver credits that may exist across our zones have been modelled, neither have any of our copper-zinc mineralization of the QF Zone, Central Polymetallic Zone and Donna Copper Zone. We do plan on looking at these additional metals in future work, which should be accretive to the project."

Aaron Stone, P.Geo, Vice President Exploration of Amex Exploration, continued, "This resource is an excellent starting point for Amex. Drilling never stops at Perron and we continue to work diligently on expanding and defining our known zones as well as exploring for further discoveries. Work has begun at site to better understand the mineralization and structure of the Team and Denise Zones to better guide infill drilling to increase their ounce count. Recent work in western zones such as Gratien, Grey Cat and Alizée have also yielded some very interesting high-grade results which need to be followed up on with further drilling. Since discovery of the JT Zone only a few months ago, our understanding of gold emplacement at Perron has been rapidly evolving and we are starting to see some geological similarities with the Windfall project. The mineralized felsic to intermediate dike that was found has given us a lot to think about for the genesis of all gold-bearing zones within the Beaupré Block. Studies have begun to validify this new theory, but if gold enrichment at Perron does turn out to be intrusion related, this will change our approach on how we search for another High-Grade Zone on the property. I am personally very excited by this as we continue to work closely with our strategic partners to unlock the full value that we believe is still to be discovered at Perron."

Victor Cantore, President and CEO, Director of Amex Exploration, added, "There are limited projects around the world that are this high-grade in nature, and the grade of the HGZ puts the Perron Project in line with these world class assets. As we move forward our goal is to build ounces while simultaneously advancing the project towards production through advancing economic studies and permitting."

Table 2: Summary of Mineral Resources at the Perron Project by zone

Note: As ounces in the High-Grade Zone increase in confidence from inferred to indicated to measured, so does the grade. This is rare in gold deposits and displays the exceptional continuity of high-grade mineralization within this zone.

Note: Drilling on the JT Zone has tripled in amount since the drill database was cut off for the resource calculation. The Company is confident that the JT Zone will significantly grow in size and is especially buoyed by its potential geological implications for mineralization contained throughout the entirety of the Beaupré Block at Perron.

Cautionary statement: These mineral resources are not mineral reserves as they do not have demonstrated economic viability. The quantity and grade of reported Inferred resources in this Mineral Resource Estimate are uncertain in nature and there has been insufficient exploration to define these Inferred resources as Indicated or Measured, and it is uncertain if further exploration will result in upgrading them to these categories. Totals may not add up due to rounding of numbers.

Please note that the Company states this is not a Maiden Resource Estimate due to a previous resource estimate completed on the Gratien Zone in 2009 for 69,907 inferred ounces of gold (please refer to SEDAR filing submitted June 2, 2009. Report is titled Resource Estimate, Form 43-101F1 Technical Report, Project Perron, is dated May 10, 2009 and was authored by Qualified Person Jacques Marchand P. Eng).

Resource Estimation Methodology and Parameters

As part of the resource estimation process, the Company and GoldMinds compiled, verified and modelled all technical information available from the Project

Parameters used in the definition of cut-of grades, modifying factors to enable reasonable prospect of economic extraction, pit constrained and mineable shapes as per CIM 2019 Guidelines.

Table 3: Parameters used for constraining resources at Perron

Perron Gold project Mineral Estimate notes:

• The mineral resource estimate is compliant with CIM 2019 standards and guidelines for reporting mineral resources and reserves.
• Resources are presented undiluted and in situ and are considered to have reasonable prospects for economic extraction. The resources at surface are constrained by pit optimization surfaces and the underground resources are constrained by mineable shapes.
• The database comprised a total of 1,533 drill holes for 617,836.50 metres of drilling (which includes historical drilling completed by previous operators) in the extent of the mineral resource, of which (312,051.20 metres) 264,462 samples were assayed as of June 30th, 2024, grid spacing are variable (The Genesis file is Amex_24 Aout 2024_MR.gnft and where the database file is BD_AMEX_08 Jul 2024_MR.accdb).
• All NQ core assays reported by AMEX were obtained by analytical methods described below under "QA&QC".
• Geological interpretation of the deposits was based on lithologies, mineralized zones orientation and the mineral observations. Each zone has its own characteristic of mineral occurrence and amount of free gold.
• Interpretation was initially made from cross-sections at intervals, and then completed in GENESIS, a modelling software, where selections of mineralization intervals were combined to generate mineralization wireframes. Envelopes are generally subvertical with various plunges.
• The mineral resource estimate encompasses a total of 189 envelopes, sub-vertical gold-bearing envelopes/domains each defined by individual wireframes with a minimum true thickness of 2.0 metres.
• Samples were composited within the mineralization envelopes into 1.0 metre length composites. A value of zero grade was applied in cases of core not assayed.
• High grade capping was done on composite data and established using a statistical analysis on a per-zone basis for gold. Capping varied from 5 g/t Au to 200 g/t Au and was applied on composites within each specific envelope.
• Density values were applied on the different mineralized zones (t/m3) varied from 2.67 to 2.83 from core measurement.
• Inverse distance squared grade estimation is used. The trial of Ordinary Kriging (OK) was rejected due to smearing and non-effective representation of high-grade areas.
• Most of the estimates are based on a block dimension of 2m North, 2m East and 2m height and estimation parameters determined by variography. The High-Grade zone has blocks of 2.5m East x 5m Z (Elevation) x 0.5m North.
• The Perron mineral resource estimate is categorized as Measured, Indicated and Inferred mineral resource as follows:
  • The Measured mineral resource category is automatic & manually defined and encloses areas where drill spacing is generally less than 30m (search radius of 15m), blocks are informed by a minimum of three drill holes, and reasonable geological and grade continuity is shown.
  • The Indicated mineral resource category is manually defined and encloses areas where drill spacing is generally less than 60m (search radius of 30m), blocks are informed by a minimum of three drill holes, and reasonable geological and grade continuity is shown.
  • The Inferred mineral resource category is manually defined and encloses areas where drill spacing is less than 130m (search radius of 65m), blocks are informed by a minimum of two drill holes, and reasonable, but not verified, geological and grade continuity is observed.
• Estimates use metric units (metres, tonnes and g/t). Metal contents are presented in troy ounces (metric tonne x grade / 31.10348).
• GoldMinds is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues, or any other relevant issue not reported in the technical report, that could materially affect the mineral resource estimate.

Further details regarding the 2024 mineral resource estimate, key assumptions, parameters and methods used to estimate the mineral resources of the Perron Gold Project will be available on SEDAR Plus () under the Corporation's issuer profile within 45 days in accordance with NI 43-101. The resource estimate will be the basis for the ongoing PEA to be released in Q4, 2024.
