Platinum Group Metals Ltd. Reports Update on Waterberg Project Infill Drill Program
Vancouver, British Columbia and Johannesburg, South Africa--(Newsfile Corp. - January 26, 2023) - Platinum Group Metals Ltd. (TSX: PTM) (NYSE American: PLG) ("Platinum Group", "PTM" or the "Company") reports that an infill drill campaign (the "Infill Drill Program") underway since November, 2022, at the Waterberg Project, located on the Northern Limb of the Bushveld Complex in South Africa (the "Waterberg Project"), is well advanced. Before a scheduled break over the recent holiday period, 16 planned T Zone boreholes and 6 of 16 planned F Zone boreholes were completed. Drilling is once again underway on site. Drill core from completed boreholes has been logged, and mineralized intercepts recovered were sampled and sent for assay by Intertek Genalysis Minerals in Australia. Final assay results for all T Zone boreholes and one F Zone borehole have now been received as follows:
|T Zone||WB288||T0||Beyond Subcrop(3)|
|T Zone||WB289||TZ||Faulted Out(4)|
|T Zone||WB292||T0||Beyond Subcrop(3)|
|T Zone||WB293||TZ||Faulted Out(4)|
- TZ = T Zone T0 = T Zero Zone CSF = Central Super F Zone.
- The true width of the shallow dipping (30° to 35°) mineralized zones are approximately 82% to 87% of the reported interval from the vertical drill hole.
- Borehole collared east of where westward dipping T Zero Zone subcrops.
- At shallow depths near the T Zone and F Zone subcrops, it was anticipated that faults may be intercepted.
The Infill Drill Program is targeting near surface, inferred and indicated mineral resource blocks that have good potential for conversion to higher confidence levels, potentially identifying additional tonnage for inclusion in early mine plans; thereby, reducing early capital expenditure and the time to first mining. Some tonnage in the resource blocks drilled in the current Infill Drill Program was included in previous mine planning for the 2019 Waterberg Project Definitive Feasibility Study (the "Waterberg DFS"). The Waterberg DFS technical report entitled "Independent Technical Report, Waterberg Project Definitive Feasibility Study and Mineral Resource Update, Bushveld Complex, South Africa" was filed on SEDAR at www.sedar.com and on EDGAR at www.sec.gov on October 7, 2019.
Portions of the T Zone have previously been categorized as inferred, indicated, and measured resources and T Zone tonnage was included in mine planning. The T Zero Zone is a mineralized layer approximately 60 metres above the T Zone. Portions of the T Zero Zone have previously been categorized as inferred and indicated but were not included in mine planning. The T Zero Zone is well developed in certain areas and one objective of the Infill Drill Program is to upgrade the confidence level for targeted areas of T Zero Zone mineralization, thereby allowing the possible inclusion of shallow T Zero Zone tonnage into feasibility mine planning.
Copper grades per tonne for all T Zero Zone and T Zone intercepts listed above averaged 0.135% and for F Zone hole WB303 ran at 0.070% in the higher-grade section. Nickel grades per tonne for all T Zero Zone and T Zone intercepts averaged 0.074% and for F Zone hole WB303 ran at 0.213% in the higher-grade section.

Platinum Group President and CEO, Frank Hallam, said, "We are very pleased with results to date for our Infill Drill Program. Assay results meet or exceed expectations and are consistent with our modelled mineral resources. The shallow, thick, high-grade intercepts confirm the impressive nature of the Waterberg deposit. Project geologists will use the results of this drill program to update the Waterberg resource estimate, which project engineers will then use to optimize the Waterberg mine plan and development schedule. More assay results for F Zone drilling will be published once they become available."
As reported previously, on October 18, 2022, project operating company Waterberg JV Resources Pty Ltd. ("Waterberg JV Co.") approved in principle a pre-construction work program of approximately US $21.0 million over a 23-month period ending August 31, 2024 (the "Work Program"). From the Work Program an initial budget of approximately US $2.5 million was approved for expenditure by March 31, 2023, and this work, including the Infill Drill Program, is underway. The Infill Drill Program also plans several shallow geotechnical boreholes and one deep exploration borehole northeast of known reserves and resources.
After assaying is complete for all boreholes described above, the remaining material will be processed to determine dry-stack tailings characteristics and provide additional concentrate metallurgical data. If dry stack tailings methods are implemented, it is estimated that Waterberg mine water consumption could be reduced by 40% to 50%.
The Company is focussed on advancing the Waterberg Project to a development and construction decision. The Waterberg Project is planned as a fully mechanised, shallow, decline access platinum, palladium, rhodium, and gold mine and is projected to be one of the largest and lowest cost underground platinum group metals mines globally.
PTM is the operator of the Waterberg Project as directed by a technical committee comprised of representatives from joint venture partners Impala Platinum Holdings Ltd. ("Implats"), Mnombo Wethu Consultants (Pty) Ltd. ("Mnombo"), Japan Organization for Metals and Energy Security (formerly Japan Oil, Gas and Metals National Corporation) ("JOGMEC") and Hanwa Co., Ltd. ("Hanwa"). Shareholders are encouraged to see the Company's filings on SEDAR (www.sedar.com) or on EDGAR (www.sec.gov) and to visit the Company's website at www.platinumgroupmetals.net.

Quality Assurance and Quality Control
The Company and Waterberg JV Co. have instituted a complete quality assurance / quality control ("QA/QC") program, including the insertion of blanks, certified reference materials (standards), and field duplicates within the sample stream. Referee analyses are also completed. The program is being followed and is to industry standard. QA/QC procedures are overseen by a qualified person, and the data has been verified and is considered reliable in the opinion of the qualified person for this news release (as described below).
NQ (47.6mm diameter) drill core is cut in-half and quartered with a diamond saw, with one-quarter placed in sealed bags and shipped to the laboratory and the other three quarters retained on site. Third party laboratory checks on 5% of the samples are carried out as well. Chain of custody is maintained from the drill to the submittal into the laboratory preparation facility.
Analytical testing was performed by the Intertek Genalysis Minerals Global Centre of Excellence, located in Perth, Western Australia. The entire sample is dried and crushed to ~2mm, of which a 300 gram split is pulverized to at least 85% of material to 75μm or better. Grade for Au, Pt and Pd is determined by using a 25g lead collection fire assay with Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) finish. On samples where the Au, Pt and Pd grade was found to be above 1 g/T, 6E analysis (for all PGEs) was done using 25g nickel sulphide collection and Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) finish. Base metals and other major elements were determined by four acid digestion with Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) finish.
