TORONTO, ONTARIO--(Marketwire - July 18, 2011) - Platinex Inc. (TSX VENTURE:PTX), is pleased to report the results of gold grain counts from 111 till samples substantiating the widespread gold in till glacial dispersion train on the Shining Tree property. Forty eight samples returned gold grain counts of 10 or more and fourteen samples returned gold grain counts greater than 25. Heavy metal concentrates from the samples contained up to 64.4 g/tonne gold. The fine fraction of the samples will be analysed for pathfinder elements and all priority sample locations are currently being targeted with detailed lodgement till and bedrock chip sampling. This will define the ensuing trenching, stripping and channel sampling phase this summer.
