Platinex Extends Shear Zones With Discovery of New Zone on Shining Tree Property

TORONTO, Dec. 10, 2020 - Platinex Inc. (CSE: PTX) (Frankfurt 9PX) (the "Company" or "Platinex") is pleased to provide an update on the ongoing exploration program at Shining Tree Gold Project, Ontario which consists of a mechanical stripping and channel sample program in the Caswell area, geological mapping and sampling and a geochemical till sampling program in advance of IP surveys and a drilling program.

In this work, Platinex has located a previously unknown shear zone north of the known extent of the Ribble Vein. This shear zone trends at 060? and two grab samples collected along it have returned 5.18 g Au/t and 3.69 g Au/t. Current interpretation of sheared quartz-carbonate alteration zones on the eastern portion of its Caswell project (see map) have them trending in an ENE direction coinciding with subtle magnetic lows. This the new discovery provides evidence for the possible continuity between the Caswell and Ronda Mine areas thereby expanding the high potential area to to1800m by 700m.

The Ribble Vein is north-south trending and appears to be folded into a gentle S shaped feature by ENE trending shears zones. A.W. Beecham, 1994¹ noted in a quote by Percy Hopkins (a former Provincial geologist) that one of the best ore sections was on a cross-cut at 30m depth at approximately 060? which assayed 12.34g/t Au over 7.0m. In addition, Beecham noted another significant result was obtained in a channel sample on surface from a vein trending at 060? which assayed 9.09g/t Au over 5.4m.

James R. Trusler, Chairman and CEO of Platinex stated, “The Caswell Prospect is situated on the east side of a 3 km diameter circle of gold deposits and former producers where the Ridout-Tyrrell deformation zone intersects the major north-south trending Michiwakenda fault. The expanded sampling program on Caswell will yield both a view to the next steps on Caswell and the bigger picture. The channel sample results from the current program will be announced prior to commencement of the drill program.”
