Group Ten Reports 4.3 Meters of 2.94 g/t Platinum, Palladium and Gold, Plus 0.24% Nickel and
Copper, at the Crescent and Cathedral Target Areas of the Stillwater West Project in Montana, USA
May 29, 2019 – Vancouver, BC - Group Ten Metals Inc. (TSX.V: PGE; US OTC: PGEZF; FSE: 5D32) (the “Company”
or “Group Ten”) announces results from the Crescent and Cathedral target areas on the east side of the
Stillwater West PGE-Ni-Cu Project, adjacent to Sibanye-Stillwater’s high-grade Platinum Group Element (“PGE”)
mines in Montana, USA . This is the fifth news release to report results of 2018 exploration programs and on-
going data synthesis and modeling work at the Company’s flagship project. Highlights include:
• Past shallow drilling at the Crescent target area includes 4.3 meters of 2.94 g/t platinum, palladium
and gold, plus 0.24% combined nickel and copper in drill hole IM2006-02, starting at 28.3 meters
depth. Mineralization in this interval is comparable to the observed grades on Platreef deposits in the
Bushveld Complex of South Africa at Anglo American’s Mogalakwena Mine and Ivanhoe’s Platreef
Mine, in a similar geological setting;
• Deeper historic drilling approximately 700 meters east of IM2006-02 includes hole CC2 which
intercepted 8.9 meters of 0.39% nickel and 0.12% copper, with no precious metals analysis;
• A total of ten past drill holes returned additional long mineralized intercepts, with a total of 15
intervals reporting greater than 25 gram-meter (g-m) grade thickness, ranging from 25.6 to 194.7
meters in length at base metal grades that are comparable to, or exceed, those of the Platreef;
• Historic drilling at the Cathedral target area includes drill hole IC01 which intercepted 6.2 meters of
0.15% nickel and 0.33% copper, with no precious metals analysis;
• 2018 and historic rock samples returned high-grade results with 12 samples over 2 g/t Total Platinum
Equivalent (“TotPtEq”) in the Crescent target area, and 22 at Cathedral. A total of 9 samples returned
over 5 g/t platinum, palladium and gold, with base metals ranging up to 0.39% nickel and 0.12%
cobalt;
• Sibanye-Stillwater controls a small block of claims in the Crescent area that host a historic resource of
approximately 260,000 ounces grading 2.39 ppm Pt+Pd1 along trend in the same conductive magmatic
target, demonstrating the potential for that target area to host significant PGE mineralization at grades
comparable to Platreef deposits;
• Results confirm that the airborne geophysical conductive highs are targeting high-sulphide
mineralization at both the Crescent and Cathedral target areas. Further, the scale of the conductive
anomalies, at 3.9 kilometers each, is equivalent to the scale of individual Platreef deposits in the
Bushveld Complex.
Michael Rowley, President and CEO, commented, "Even in the less-explored Crescent and Cathedral target areas
we continue to see correlating geophysical and geological data that confirms the potential for large-scale PGE-
Ni-Cu-Co mineralization within the Ultramafic and Banded Series along the 25 kilometer strike of the project.
Work to date demonstrates the presence of Platreef-style grade in these two target areas within conductive high
anomalies that, at nearly four kilometers each in size, show the potential for bulk tonnage scale. Like our other
target areas at Stillwater West, the strongest conductive anomalies have only seen limited drilling to date, and
the identified mineralization is open for expansion in all directions. We look forward to further announcements
including our exploration plans for 2019 in the very near future.”
Crescent and Cathedral are the two easternmost target areas of eight bulk tonnage targets identified in the
synthesis and modeling work by Group Ten Metals (see Figure 1), centering on geophysical conductive high
anomalies with mineralization confirmed by drill and rock sample results.

Figure 1 – Fourteen Target Areas Across the 25-Kilometer Length of the Stillwater West Project
Crescent Target Area
As shown in Table 1 and Figures 2 and 3, ten shallow drill holes define an area approximately 250 meters by 500
meters on the western portion of the target area in which all holes returned significant mineralized intercepts
and mineralization remains open in all directions. Nine of those holes returned grade-thickness values of more
than 25 gram-meter (g-m) TotPtEq, and five over 100 g-m grade thickness. Grade-thickness values, determined
as grade x thickness, of 25 gram-meter or more are considered economically significant, and values of 100 to
300 gram-meter are considered exceptional. Grade-thickness values at the adjacent J-M Reef mines average
approximately 34 gram-meter palladium and platinum1.
Hole IM2006-02 returned 166 g-m grade-thickness TotPtEq including 4.3 meters of 2.94 g/t 3E (Pt + Pd + Au)
plus 0.24% Ni+Cu starting at just 28.3 meters depth, demonstrating grade that is directly comparable to that of
the Platreef over potentially minable width s. Hole IM2006 -02 also returned a number of other mineralized
intercepts including 1.0 meter at 11 g/t 3E and 4.7 meters of 0.68 g/t 3E plus 0.63% Ni+Cu.
Located approximately 700 meters to the east of IM2006-02, hole CC2 confirms mineral ization laterally along
the layered magmatic system, while also providing a deeper test to the Basal Series. Drilled by Anaconda in 1990,
CC2 reached 569 meters deep and returned multiple mineralized intervals including 1.2 meters grading 0.13%
Ni and 4.08% Cu, and 8.9 meters grading 0.39% Ni and 0.12% Cu, starting at 532 meters down hole. Precious
metals were not analyzed in this historic drill hole but would be expected to occur with these base metal
sulphides.
Reconnaissance rock sampling and geological mapping results from 2018 and previous campaigns confirm the
grade potential of the Crescent target area with 12 rock samples reporting greater than 2 g/t TotPtEq, ranging
up to 10.54 g/t TotPtEq . In addition, high-grade palladium results in rock samples include up to 5.74 g/t and
7.64 g/t Pd with strong base metal results of up to 0.377% and 0.391% Ni, and 0.12% Co.
As shown in Figures 2 and 3, historic drilling on a small block of adjacent claims held by Sibanye-Stillwater led to
the development of a historic resource of approximately 260,000 ounces grading 2.39 g/t platinum and
palladium, along trend of the same conductive magmatic target . While not on Group Ten’s claim block, these
results demonstrate the potential in that target area to host significant PGE mineralization at grades comparable
to Platreef deposits and confirm that the observed electro-magnetic conductive anomalies are targeting nickel-
copper sulphide mineralization.
Cathedral Target Area
Cathedral is one of the least explored target areas at Stillwater West, however existing data reports high-grade
PGE results in geological mapping which correlates with the conductive geophysical high noted above. Results

from the only drill hole with surviving data report significant base metal grade and width with 6.2 meters of
0.15% Ni plus 0.33% Cu in IC-01, confirming that the conductive highs are targeting significant nickel and copper
sulphide mineralization. Precious metals were not analyzed in this historic drill hole but would be expected to
occur with these base metal sulphides.
Reconnaissance surface sampling to date, presented in Table 3, returned 22 samples with over 2 g/t TotPtEq
with seven results over 5 g/t platinum, palladium and gold. Strong rhodium values are also noted, with five
samples returning more than 0.56 g/t Rh. Rhodium values have not been included in the calculation of metal
equivalents in the tables above and below.
Table 1 – Drill Results – Crescent Target Area
Intercepts with grade-thickness values over 25 gram-meter TotPtEq, plus select lesser intervals, are presented above. Total Platinum Equivalent (TotPtEq
g/t) and Total Nickel Equivalent calculations reflect total gross metal content using metals prices as follows (all USD): $6.00/lb nickel (Ni), $3.00/lb copper
(Cu), $20.00/lb cobalt (Co), $1 ,000/oz platinum (Pt), $ 1,000/oz palladium (Pd) , and $1 ,250/oz gold (Au) . Values have not been adjusted to reflect
metallurgical recoveries. Total metal equivalent values include both base and precious metals, where available. Results labelled ‘n/a’ were not assayed for
that metal. Total platinum equivalent grade-thickness was determined by multiplying the thickness (in meters) by the Total Platinum Equivalent grade (in
grams/tonne) to provide gram -meter values (g-m) as shown. Total nickel equivalent grade-thickness was determined by multiplying the thickness (in
meters) by the Total Nickel Equivalent grade (in percent) to provide percent-meter values as shown. IM series drill holes were conducted by Group Ten’s QP
and are not considered historic. CC series drill are considered historic and have not been independently verified by Group Ten.

Next Steps
Follow up target definition work is planned for both the Crescent and Cathedral target areas to develop and
allow prioritization of future targets for testing. Planning is currently underway for the next phase of drill testing
at the advanced target areas at Stillwater West project including Iron Mountain and Chrome Mountain with the
objective of offsetting higher-grade mineralized intercepts that show the potential to be rapidly advanced to a
resource delineation stage. Additional synthesis and modelling work is underway on less advanced areas at
Stillwater West to develop and refine targets for drill testing. News flow will be on-going to report on this effort
in addition to announcing exploration plans.
About Stillwater West
The Stillwater West PGE-Ni-Cu Project positions Group Ten as the second largest landholder in the Stillwater
Complex, adjoining and adjacent to Sibanye-Stillwater’s world-leading Stillwater, East Boulder, and Blitz
platinum group elements (PGE) mines in south central Montana, USA. With more than 41 million ounces of past
production and current M&I resources, plus another 49 million ounces of Inferred resources2,3, the Stillwater
Complex is recognized as one of the top regions in the world for PGE-Ni-Cu mineralization, alongside the
Bushveld Complex and Great Dyke in southern Africa, which are similar layered intrusions. The J-M Reef, and
other PGE-enriched sulphide horizons in the Stillwater Complex, share many similarities with the highly prolific
Merensky and UG2 Reefs in the Bushveld Complex, while the lower part of the Stillwater Complex also shows
the potential for much larger scale disseminated and high-sulphide PGE-nickel-copper type deposits, possibly
similar to Platreef in the Bushveld Complex4. Group Ten’s Stillwater West property covers the lower part of the
Stillwater Complex along with the Picket Pin PGE Reef-type deposit in the upper portion, and includes extensive
historic data, including soil and rock geochemistry, geophysical surveys, geologic mapping, and historic drilling.
