Vancouver, British Columbia--(Newsfile Corp. - June 17, 2024) - Onyx Gold Corp. (TSXV: ONYX) (OTCQX: ONXGF) ("Onyx" or the "Company") is pleased to announce results from four drill holes completed during its 2024 Spring Drill Program (the "Program") at its Munro-Croesus Project ("Munro-Croesus" or the "Project") in the Timmins gold camp, Ontario (Figure 1).
The four drill holes reported today were completed at the Argus Zone, a near-surface bulk tonnage target located three kilometers ("km") northwest of the past-producing Croesus Gold Mine. The Croesus Mine yielded some of Ontario's highest-grade gold ever mined and is where Onyx discovered the new near-surface, high-grade GM Vein earlier this year. Significant 2024 Argus drill results to date are reported in Table 1.
The latest drilling continues to show improved grade and width as the Argus Zone is tracked west toward its convergence with the Pipestone fault. The Pipestone fault is a key regional structure known to host material gold deposits, including Mayfair Gold's 3.5 million-ounce Fenn-Gibb deposit located 6.1 km to the southeast of the Argus Zone (Figure 2).
2024 Argus Drilling Highlights:
- Highlight Assay Results for Argus Zone:
0.99 grams per tonne gold ("g/t Au") over 63.3 meters ("m"), including 2.18 g/t Au over 17.4 m, and 0.83 g/t Au over 29.0 m, including 2.42 g/t Au over 8.2 m, in hole MC24-166
0.84 g/t Au over 22.9 m, including 2.23 g/t Au over 4.4 m, in hole MC24-164
0.44 g/t Au over 32.5 m, including 1.01 g/t Au over 7.5 m, in hole MC24-165
- The Argus Zone has now been defined over a strike length of 750 m and a width of 200 m and remains open in all directions.
- Drilling at the Argus Zone has focused on 50-meter step-outs from the previously reported intercept in hole MC23-140, which returned 0.96 g/t Au over 27.6 m") (See Company press release from January 23, 2024).
- Hole MC24-166 intersected two significant zones, returning 0.99 g/t Au over 63.3 m, including 2.18 g/t Au over 17.8 m, and 0.83 g/t Au over 29.0 m, including 2.42 g/t Au over 8.2 m. These intersections more than double the width observed in hole MC23-140 and highlight the increasing potential of expanding the Argus Zone to the west.
- Hole MC24-165, a further 150-meter western step-out along trend from hole MC24-166, returned 0.44 g/t Au over 32.5 m, including 1.01 g/t Au over 7.5 m, within the Porcupine sediments, south of the Pipestone fault with the characteristic fine quartz veining and specular hematite typically associated with the Argus Zone. This intercept has significant implications for continued exploration within this rock type, as all other intersections of Argus Zone mineralization are hosted in mafic volcanics north of the Pipestone fault.
- Assay results for a final fifth hole, MC24-163, are undergoing further check assays at the ALS Canada laboratory in North Vancouver, BC. and will be reported when results are received and reviewed to meet the Company's quality assurance and quality control protocols.
"MC24-166 is a great hole," said Brock Colterjohn, President & CEO. "We are very pleased with all the results we've received to date at our Timmins programs. The Argus results, along with the GM Vein results earlier this year, confirm that there is still ample opportunity for new discoveries in this historic camp. It has been our thesis that the Argus Zone could get stronger and thicker as we stepped out west towards the Pipestone Fault. Not only did our results from 2023 validate this by doubling the strike length of the zone, but this year's drilling further confirms our approach, increasing the zone by more than 250 meters within an area of considerably higher grade and width. We are excited about the potential for the Argus Zone to expand and are looking forward to going back in to continue drilling this impressive new zone further to the west."
Discussion of Results for the Argus Zone
The bulk-tonnage style Argus Zone is located three km west-northwest of the past-producing Croesus Mine (Figure 2). It is a broad zone of near-surface gold mineralization within the influence of the regional gold-bearing Pipestone Fault. The Argus Zone is characterized by silicified mafic variolitic volcanics cut by northeast-trending pyritic veinlets (with trace to minor arsenopyrite) within a broader halo of carbonate alteration and local development of specular hematite.
All four drill holes released today continued to intersect promising gold mineralization over encouraging widths. The results from hole MC24-166 highlight the continuation of the Argus mineralization system to the west with apparent improving gold grades and intersected widths as the zone approaches the northwest-trending Pipestone Fault and a prominent northeast-trending Barton Creek Fault. The Company is developing a follow-up drill plan with further holes planned to the west across the northeast-trending fault to follow the continuation of the Argus Zone.
Discussion of the 2024 Spring Drill Program
A total of 25 holes (MC24-143 to 167) totaling 3,311 m were drilled on the Munro-Croesus Project in March and April, including 20 holes totaling 1,731 m on the GM Vein and five (5) holes totaling 1,580 m on the Argus Zone. The remaining hole, MC24-163, will be released once the final assays results are received and reviewed to meet the Company's quality assurance and quality control protocols.
The Munro-Croesus Project
The Munro-Croesus Project is located along Highway 101 in the heart of the Abitibi greenstone belt, Canada's premier gold mining jurisdiction (Figure 1). This large, 100% owned land package includes the past-producing Croesus Gold Mine, which yielded some of the highest-grade gold ever mined in Ontario. Extensive land consolidation from 2020-2023 has unified the patchwork of patented and unpatented mining claims surrounding the Croesus Gold Mine into one coherent package (Figure 2) and enhanced the project's exploration potential.
The Project covers 93 km2 of highly prospective geology within the influence of major gold-bearing structural breaks. Bulk-tonnage gold deposits located in the immediate region include the Fenn-Gib gold project being developed by Mayfair Gold Corp. that contains an Indicated Resource of 3.38 Moz at 0.93 g/t Au and an Inferred Resource of 157 koz at 0.85 g/t Au, and the Tower Gold Project being developed by STLLR Gold Inc. that contains an open pit Indicated Resource of 4.46 Moz at 0.92 g/t Au and an Inferred Resource of 8.29 Moz at 1.09 g/t Au1.

Additional Notes:
Starting azimuth, dip and final length (Azimuth/-Dip/Length) for the four drill holes reported today are noted as follows: MC24-164 (000/45/347), MC24-165 (315/45/450), MC24-166 (325/45/225), and MC24-167 (000/45/249).
Samples of drill core were cut by a diamond blade rock saw, with half of the cut core placed in individual sealed polyurethane bags and half placed back in the original core box for permanent storage. Sample lengths typically vary from a minimum 0.2-meter interval to a maximum 1.5-meter interval, with an average 0.5 to 1.0-meter sample length. Drill core samples were delivered by truck in sealed woven plastic bags to ALS Geochemistry laboratory facility in Timmins, Ontario for sample preparation with final analysis at ALS Geochemistry Analytical Lab facility in North Vancouver, BC. ALS Geochemistry operate meeting all requirements of International Standards ISO/IEC 17025:2017 and ISO 9001:2015.
Gold is determined by fire-assay fusion of a 50-gram sub-sample with atomic absorption spectroscopy (AAS). Samples that return values >10 ppm gold from fire assay and AAS are determined by using fire assay and a gravimetric finish. Various metals including silver, gold, copper, lead and zinc are analyzed by inductively-coupled plasma (ICP) atomic emission spectroscopy, following multi-acid digestion. The elements copper, lead and zinc are determined by ore grade assay for samples that return values >10,000 ppm by ICP analysis. Silver is determined by ore-grade assay for samples that return >100 ppm. All ALS Geochemistry sites operate under a single Global Geochemistry Quality Manual that complies with ISO/IEC 17025:2017. ALS Geochemistry follows the quality management and operational guidelines set out in the international standards ISO/IEC 17025 - "General Requirement for the Competence of Testing and Calibration Laboratories" and ISO 9001 - "Quality Management Systems".
The Company maintains a robust QA/QC program that includes the collection and analysis of duplicate samples and the insertion of blanks and standards (certified reference material).
