Platinex Intersects Widespread Gold Mineralization in Maiden Drill Program at Heenan including 77.44 m of 0.40 g/t Au and 27.15 m of 0.55 g/t and Announces Board Reorganization

TORONTO, Feb. 21, 2024 (GLOBE NEWSWIRE) -- Platinex Inc. (CSE: PTX) (OTCQB: PANXF, Frankfurt: 9PX) (“Platinex” or the “Company”) is pleased to announce results from the first phase of diamond drilling on the Heenan Property, part of the Heenan Mallard Gold Project located in the Swayze Greenstone Belt of the Abitibi northeastern Ontario and held through the South Timmins Mining Joint Venture (“South Timmins JV”) with Fancamp Exploration Ltd.*Highlights:*

· The program totalled 611.50 m with three drill holes completed over 50 m spacing and one undercut hole. All cross sections for the four holes are on the website.· Several consistent wide zones of gold mineralization intersected from surface to 177m including:
· 77.44 m of 0.40 g/t Au in hole HE23-02 and,

· 27.15 m of 0.55 g/t Au in hole HE-23-03 with higher-grade intercepts within (see Table 1).
· An additional zone of mineralization, outside of the iron formation, was encountered in hole 2 grading 5.53 g/t over 1.00 m at 177 m.· The drill program is the first drill program completed on the project and was focused on results obtained from past geochemical and prospecting programs, including those from the mechanized stripping program completed in Q4 2023^1 that discovered gold occurrences in two channel sample composites including 4.05 g/t Au over 2.00 m, and 2.39 g/t Au over 8.00 m in Trench 2.· Gold mineralization is hosted mainly within the Woman River Iron Formation and is associated with pyrite mineralization, alteration, and minor quartz veining.

· The Heenan Mallard Property is located along the northwest border of IAMGOLD’s Cote Gold Project, which is set to commence production in March 2024 and Southeast of Evolution Mining’s October gold project.“We are encouraged with the results of the maiden drill program at Heenan which was not only completed successfully but also on budget, said Greg Ferron, President and CEO of Platinex Inc. “The distribution of gold mineralization is widespread and intersected gold in all four holes across a 100-metre strike length, demonstrating the potential of this emerging gold project.”

The Property is located in Heenan and Benton Townships lying within the Swayze area of the Abitibi Greenstone Belt and is found on the fold nose of the Woman River Iron Formation, a high-magnetic and structural target considered favourable for gold mineralization.

The South Timmins joint venture plans to continue its systematic approach to exploring the South Timmins JV properties and to follow up on this greenfield discovery at Heenan.

*Program Summary:*
During the months of December 2023 and January 2024, four diamond drill holes totaling 611.50 m were completed.

Drill hole HE23-01 was collared to drill underneath the surface mineralization encountered in Trench 2. The drill hole intersected numerous zones of gold mineralization, including:

· 0.64 g/t Au over a sampled length of 5.00 m,
· 0.27 g/t Au over a sampled length of 13.20 m, and
· 2.07 g/t Au over a sampled length of 1.00 m.Drill hole HE23-02 was collared approximately 50 m grid east to test the strike length of the Woman River Gold Zone southeast of Trench 2. The drill hole intersected:

· 0.40 g/t Au over a sampled length of 77.44 m, including higher grade intercepts such as 1.64 g/t Au over a sampled length of 4.00 m,  
· 2.08 g/t Au over a sampled length of 1.20 m,
· 2.20 g/t Au over a sampled length of 0.60 m, and,
· 5.53 g/t Au over a sampled length of 1.00 m.

Drill hole HE24-03 was collared 50m grid East of HE23-02, to test surface mineralization encountered from prospecting in Trench 1. The drill hole intersected:

· 0.55 g/t Au over a sampled length of 27.15 m, including 3.18 g/t Au over a sampled length of 0.40 m, and,
· 1.16 g/t Au over a sampled length of 6.70 m.

Drill hole HE24-04 was collared underneath HE23-01 at a steeper inclination and intersected anomalous gold throughout the hole, with the best intercept:  

· 1.00 g/t Au over a sampled length of 3.00 m.Significant results and collar information is provided in Tables 1 and 2 below.
