Platinex Makes New Gold Discovery at Heenan Property in the Swayze Area of the Abitibi Greenstone Belt
Toronto, Ontario, November 09, 2023 – Platinex Inc. (CSE: PTX) (OTCQB: PANXF, Frankfurt: 9PX) (“Platinex” or the “Company”) is pleased to announce results from its exploration program on the Heenan Property, part of the Heenan Mallard Gold Project held through the South Timmins Mining Joint Venture (“South Timmins JV”) with Fancamp Exploration Ltd.
The Heenan Property is located in Heenan and Benton Townships in northeastern Ontario and lies within the Swayze area of the Abitibi Greenstone Belt (Figure 1). The Property is located on the fold nose of the Woman River magnetic high indicating a structural target favourable for gold which formed the basis for the exploration program. Heenan is immediately adjacent to Northern Superior Resources’ “October Gold” Property (recently optioned by Evolution Mining Ltd.) and along the northwest border of IAMGOLD’s soon-to-be-producing Côté Gold Project.
- Greenfield gold discovery generated through B-horizon soil geochemical surveys, prospecting, and channel sampling.
- 13 channel samples returning > 0.5 g/t Au with a high of 7.50 g/t Au, included in two channel samples that returned composite weighted averages of 4.05 g/t Au over 2.00 m and 2.39 g/t over 8.00 m in Trench 2.
- Gold mineralization is associated with narrow concordant felsic to intermediate intrusive dykes within the iron-formation and metavolcanic sequence.
Joerg Kleinboeck, P.Geo., South Timmins JV’s Exploration Manager, states, “This is an exciting development for the South Timmins JV. The stripping program is part of a systematic approach taken where initial geochemical and prospecting programs identified an area of interest that was targeted with the recent channel sampling program. This approach has led to a greenfield discovery in the emerging Swayze camp.”

The Company recently completed mechanized stripping of selected areas that focused on highly anomalous geochemical and follow-up prospecting results. A total of 618 m2 were mechanically stripped and washed in two areas.
A total of 41 selective channel samples were collected and submitted for analysis. Channels were cut at 1 m lengths, and, except for Channel 5 on trench 2, were cut perpendicular to geological contacts and were occasionally offset due to overburden or water.
Results ranged from <5 ppb to 7,500 ppb Au (7.50 g/t Au), with 13 samples returning > 0.5 g/t Au. Gold mineralization is associated with narrow concordant felsic to intermediate intrusive dykes within the iron-formation and metavolcanic sequence. Sample highlights are tabulated below (Tables 1 and 2) and shown in Figures 2 and 3.
The Company is currently planning a late fall or early winter Phase 1 drill program to follow up on these results. Details of the drill program will be provided shortly in a separate update.

Heenan is located within the Woman River anticline and is centered on the Woman River iron formation, which divides overlying mafic volcanic rocks of the October Lake formation to the northwest and west from underlying, calc-alkaline, felsic to intermediate volcanic rocks and sub-volcanic porphyries of the Strata Lake formation to the southeast. The Strata Lake formation occurs within the upper portions of the Marion Group which is thought to correlate with the Deloro assemblage of the southern Abitibi belt, based on U-Pb geochronology (van Breemen, et.al, 2006). Van Breemen, et.al., describe the upper portions of the Strata Lake formation as “dominated by variably chloritized and sulphidized volcanic rocks related to crackle breccia zones that are interpreted to represent paleo-hydrothermal conduits for iron-rich fluids that precipitated out of the overlying ironstones”.
The iron formation located at the west end of the Property appears to have been displaced at a possible fold nose for a distance of approximately 1.1 km by a dextral strike-slip fault, informally termed the Mallard Shear zone, a regional structure which is part of several northwest–southeast directed fault structures that may have provided conduits for hydrothermal fluids to deposit mineralization at favorable horizons within the stratigraphy, particularly at the contact of the felsic volcanic rocks with the iron formations (Flanagan, 2018).
The Property was acquired by Fancamp Exploration Ltd. in 2018 and greenfield exploration work including soil sampling, prospecting, and geophysics (Spectral IP) was carried out during the period from 2018-2020. In 2023, a 75% interest in the Property was acquired by Platinex through the South Timmins Joint Venture transaction with Fancamp Exploration Ltd.
Channel samples were collected and delivered by representatives of Platinex to Activation Laboratories Ltd. in North Bay, Ontario. Activation Laboratories Ltd. is an ISO 17025:2005 accredited testing laboratory. Platinex completes duplicate samples and inserts standards and blanks as part of its QA/QC program. As well, several samples are selected for check analysis. Activation Laboratories also performs an internal QA/QC program which includes the insertion of CRM’s, blanks, sample repeats, and duplicate samples. Samples were analyzed using the RX1, and 1A2 packages with a gravimetric finish (1A3) for samples that returned greater than 5,000 ppb Au.
True widths of the mineralization have not yet been determined.
