Platinum Group Metals Ltd. (PTM-TSX; PLG-NYSE MKT) (“Platinum Group” or the “Company”) announces that new drill intercepts have doubled the strike length of the Waterberg discovery to a total of 5.5 kilometers. The newly discovered Waterberg platinum deposit remains open along strike and up-dip.
Results announced today include 24.00 meters grading 4.32 g/t 2E +Au within a larger intercept of 58.00 meters of 2.98 g/t 2E+Au (Hole WB027). Results also include 11.5 meters grading 7.18 g/t 2E + Au (Hole WB031) and 8.5 meters of 4.8 g/t (WB-034). These new F layer intercepts are located on strike to the north of the area where the previously announced 6.6 million ounce inferred mineral resource estimate (Initial mineral inferred resource estimate of 68 million tonnes at 3.01 g/t 3E, comprised of 0.94 g/t Pt, 1.71 g/t Pd, 0.37 g/t Au, Technical Report dated September 1st 2012 at www.Sedar.com) has been identified. The grade-thickness on the F layers is increasing as exploration progresses to the north.
Recent drilling has expanded the F mineralized layers for 2.7 kilometers beyond the initial resource area to the northern boundary of the current Waterberg Joint Venture (in which Platinum Group has a 49.9% effective interest; Japan Oil, Gas and Metals National Corporation (“JOGMEC”) has a 37% and the effective balance with a BEE company). Platinum Group holds an effective 87% interest in Prospecting Permit Applications over ground immediately to the north of the F layer intercepts announced today in Hole WB-034. Geochemistry and geophysical surveys all suggest a significant strike extension potential to the north under shallow cover.
The Waterberg Joint Venture has the Prospecting Permit to the east and immediately up-dip of the Waterberg deposit and up-dip of the intercepts announced today under, an application in process with the Department of Mineral Resources, “DMR”.
The initial inferred mineral resource estimate of 6.6 million ounces covers an area of approximately 2.5 million square meters with 3.7 million inferred ounces on the F layers (refers to the Technical Report dated September 1st 2012 at www.Sedar.com). The current intercepts provide a significant increase in the target area for high grade thickness platinum mineralization.
The T mineralized layers come to approximately 140 meters from surface in the initial resource area and the T layers are projected to be to the west of the F layer intercepts announced today. The T layers remain open for further drilling and resource definition along strike and down-dip and add to the target scale. The T layers have been intercepted to 1,375 metres deep in the main resource area and below it. The earlier resource estimate cut-off the mineralization using preliminary potential economic considerations at a depth of 1,000 meters. The added potential scale of the deposit from the current drilling may result in a re-consideration of this cut-off depth as the larger scale will affect the potential economic considerations positively. However, the focus of continued exploration will be on near surface mineralization. All mineral resource estimates and intercepts announced to date are on granted Prospecting Permits. The metal ratios and layering position of the new F layer intercepts are consistent with those found within the initial resource area.
The intercepts in the table above shown as “FH+FP” include the grade of the middling between the FH and FP layers. Consideration of the potential mineralized cut as one zone or two will depend on the size of the middling and will be determined with further work. Hole WB 033 did not intersect significant values. Interestingly, this is the first of 33 holes since the discovery at Hole WB 003 that did not have significant values. Re-logging and interpretation of WB 033 is being carried out. It is unclear at this time if WB 033 intercepted a pot hole, a fault or a geological interruption by a cross cutting unit. A deflection from this location is in progress.
The F and T layers are correlated in stratigraphic position within the newly outlined Bushveld Complex area and certain lithological and chemical markers also add to the correlation. In-fill drilling completed for holes WB 017 to WB 032 (not reported herein) have added confidence to the initial resource area. The metal ratios have reasonable consistency for a layered magmatic deposit style. The University of the Witwatersrand (“Wits”) has sent several senior geologists and students to site and have commenced several detailed geological studies on the new discovery. Initial thesis work in progress at Wits including rock and mineral identification detail has confirmed the Company’s “new Bushveld layered” discovery model.
Qualified Person, Quality Control and Assurance, Verification
R. Michael Jones, P.Eng, (CEO and shareholder), is the non-independent Qualified Person for this press release. He has relevant experience in platinum exploration for the past 10 years and precious metals exploration and mine operations over the past 25 years. Mr. Jones has verified the data and is satisfied that the confidence of the data, the geological interpretation and estimates are sufficient for this disclosure. He has visited the property and reviewed the core and sampling on numerous occasions in 2011 and 2012. Ken Lomberg is the Independent (as defined in NI-43-101) Qualified Person (“QP”) for the Inferred mineral resource estimate released on September 5, 2012.
Quality control and assurance was completed in the normal process for Platinum Group Metals RSA Pty Ltd. Standards, duplicates and blanks were inserted regularly in every assay batch. These assay results were checked and any results outside of two standard deviations were re-assayed. Strict control and documentation on the core from the drill rig to the site and the assay samples to the lab were maintained at all times under a chain of custody sign off system. The platinum group elements were assayed by fire assay using a nickel sulphide collection method at Setpoint Laboratories, Johannesburg, a SANAS accredited laboratory. Thys Botha, a qualified geologist and resource estimator in the full time employ of Platinum Group Metals RSA (Pty) Ltd., has supervised the work and compilation of the results.
