Platinum Group Metals Ltd. Advances Resource Drilling at Waterberg; Multiple Thick, High Grade Mining Areas Targeted in Upcoming Pre-Feasibility Study
VANCOUVER, BRITISH COLUMBIA and JOHANNESBURG, SOUTH AFRICA--(Marketwired - Mar 17, 2016) - Platinum Group Metals Ltd. (TSX:PTM)(NYSE MKT:PLG) ("Platinum Group" or the "Company") is pleased to announce that over 90% of recent infill drilling on the Waterberg deposit has successfully intersected the "T" and "F" targeted layers. The deposit has been extended both up-dip and at depth.
New features from recent drilling include:
- Multiple High Grade "Super T zone" intercepts including 13.91 g/t platinum, palladium and gold ("3E") over 11.87 meters; and
- Multiple "Super F zone" intercepts creating targets for shallow resources at less than 300 meters vertical from surface.
Confirmation drilling has delineated large scale F zone blocks at grades higher than the deposit average which can be separately modelled and prioritized for mining in an ongoing Pre-Feasibility Study. New high grade T zone blocks are also emerging at depth. Additional drilling to offset these new high grade T zone intercepts has been approved by the Waterberg Joint Venture and is now underway. The Japan Oil, Gas and Metals National Corporation ("JOGMEC") is funding the current drilling and Pre-Feasibility engineering work.
R. Michael Jones, President, CEO and co-founder of Platinum Group Metals said "Definition drilling is allowing us to model Waterberg as a series of potential mining areas rather than as one 13 kilometer deposit. Given the scale of known resources, and being only 140 meters from surface, Waterberg is certainly big and shallow. The definition drilling results allow us to target the best grade in five large potential mining blocks, each at a scale typical of a stand-alone South African platinum mine shaft or decline complex. The new emerging high grade T zone adds a completely new dimension. Waterberg will now be considered a mining district to be prioritized rather than as a single deposit in the ongoing Pre-Feasibility Study."
The 27 new drill holes (15,500 meters of core) reported herein, plus results from 265 earlier holes (249,000 meters of core) completed for the previous July 2015 resource estimate, outline five potential mining areas: T zone, Super T, Central Super F, Boundary Super F and Northern Super F. A total of 7 holes and 6,000 assays are still pending at this time from the ongoing drill program.
Higher grade intercepts reported herein, combined with earlier higher grade cuts, create specific blocks to be considered in pre-feasibility mine planning and engineering work. An updated resource calculation is in progress, modelled on 2.5 g/t, 3.5 g/t and 4.0 g/t platinum, palladium, rhodium and gold ("4E") lower cut-off grades for the identified blocks.
New Highlight Drill Results
Super T borehole details are listed below. The term "Super" designates an intercept thickness of greater than 6 meters at over 5 g/t. In the F Zone "Super is used for an intercept of more than 10 meters. True thickness is approximately 79% of the reported intercept width. It is logical to consider intercepts at up to 6 meters vertical thickness for standard mechanized mining methods. At 6 to 10 meters thick other methods for mechanized extraction can be considered. Beyond 10 meters thick bulk underground mining methods may be considered.
To put the Super T and Super F intercepts into perspective, a common measure for mine planning comparison in layered deposits is thickness multiplied by grade measured in centimeter grams per tonne ("cmg/t"). An intercept of 10 meters of 3 grams per tonne or an intercept of 6 meters of 5 grams per tonne both have 30,000 cmg/t. By comparison a typical Merensky reef platinum mine would have 1 meter of 6 grams per tonne or 600 cmg/t.
New "Super" T - The following holes define an emerging Super T zone:
| Hole WB195 - 13.91g/t 3E over 11.87 meters (or 15.03 g/t 3E over 8.68 meters, from 898.32 meters to 907.0 meters); | |
| Hole WB186 - 5.84 g/t 3E over 19.00 meters from 812.00 meters to 831.00 meters (this hole announced December 4, 2015); and | |
| Hole WB200 - 5.92 g/t 3E over 7.56 meters from 938.44 meters to 946 meters. |
Earlier T zone drilling in this area up-dip from the Super T zone includes:
| Hole WB032 - 5.04 g/t 3E over 4.25 meters from 799.67 meters to 803.92 meters (this hole drilled November, 2011); | |
| Hole WB187 - 9.97 g/t 3E over 3.41 meters from 681.59 meters to 685.00 meters (this hole announced December 4, 2015); and | |
| Hole WB188 - 10.28 g/t 3E over 4.50 meters from 633.50 meters to 638.00 meters (this hole announced December 4, 2015). |

About Waterberg
Waterberg was newly discovered by the Company and its joint venture partners including JOGMEC the Japanese State Company in late 2011. Waterberg was hidden from previous exploration by 140m of sedimentary cover which is the reason it was not previously found. Waterberg has been studied since its discovery in co-operation with Witwatersrand University and its mineralogy and age date have suggested it is a Bushveld Complex deposit but in a new set of layers and geological domain. Waterberg is not aligned with the classic South African platinum reefs of the Merensky, UG-2 or the Platreef. The Waterberg has been metallurgical tested and found to produce a desirable concentrate with similar characteristics to the preferred Merensky Reef.
Resources at Waterberg total:
25.64 million 3E ounces Inferred plus 12.61 million 3E ounces Indicated
Inferred - 246 million tonnes grading 3.25 g/t 3E (0.98 g/t Pt, 2.11 g/t, Pd, 0.16 g/t Au, 2.50 g/t cut-off)
Indicated - 121 million tonnes grading 3.24 g/t 3E (0.97g/t Pt, 2.11 g/t, Pd, 0.16g/t Au, 2.50 g/t cut-off)
(See Independent Technical Report by C. Muller of CJM Consulting South Africa (Pty) Ltd. dated Sept 4, 2015 at www.sedar.com for details)
These resources will be updated with the results of the drilling announced today and other drilling completed before the end of March 2016.
