Provides Waterberg Project UpdateVancouver, British Columbia and Johannesburg, South Africa--(Newsfile Corp. - October 14, 2021) -  Platinum Group Metals Ltd. (TSX: PTM) (NYSE American: PLG) (\"Platinum Group\" \"PTM\" or the \"Company\") provides the following Waterberg Project update:Geotechnical DrillingA geotechnical drilling campaign at the Waterberg Project, which commenced in July 2021, is now in process of completion and demobilization. The geotechnical drilling campaign consisted of 46 boreholes drilled along the planned centerline of two sets of twin declines and box-cut positions. Approximately 11 holes were drilled vertically, and the remaining holes were inclined out of the plane to intersect all possible discontinuities. A total of 5,966 metres of drill core were recovered and a total of 2,696 metres of core were geotechnically logged from within the zone of interest. All boreholes except those in the planned box-cut areas were backfilled with cement upon completion. Downhole geophysical surveys were conducted consisting of optical and/or acoustic televiewer and gamma probes as well as caliper probes. Three packer tests were conducted in boreholes where groundwater strikes were encountered. Core samples of all the major geotechnical units encountered were collected and subjected to laboratory testing.The results of the drilling campaign confirm that the box-cut positions are in sandstone, and the central and southern declines transition from sandstone into a dolerite sill and back into sandstone before cutting into the igneous rocks of the Bushveld Complex. In general, results are as expected, and the rock mass is competent. Also as expected, some support will be required for both tunnel sets. No problem areas, where special mining methods or non-standard support would be required, have been identified. Groundwater inflow is also not considered a risk. The standard practice of probe drilling ahead of decline tunnel development will be important to monitor rock quality and identify correct support standards ahead of development. Geotechnical qualified persons monitoring the drill programme have stated that in general, the rock mass encountered along both decline routes can support the planned excavations with no major problem areas expected.Community RelationsOn and following March 5,...
