Group Ten Metals Announces Discovery of Hybrid Zone as One of 14
Multi-Kilometer-Scale PGE-Ni-Cu Target Areas Identified at Stillwater West
December 17, 2018 – Vancouver, BC - Group Ten Metals Inc. (TSX.V: PGE; OTC: PGEZF, FSE: 5D32) (the
“Company” or “Group Ten”) provides an update on the Company’s flagship Stillwater West PGE-Ni-Cu project
(“Stillwater West” or the “Project”) in the Stillwater district of Montana, USA, including a summary of 2018
field work which resulted in the recognition of the new Hybrid Zone PGE-Ni-Cu-Cr target that is one of 14
multi-kilometer priority target areas identified by field and data analysis activities to date.
Dr. Craig Bow, Chief Geologist, stated “We are excited about the discovery of a fundamentally new type of
platinum and palladium mineralization within the Stillwater Complex. Termed “Hybrid Zone” due to the
complex mixtures of rock types and textures, this zone within the Chrome Mountain target area is
characterized by broad intervals (10 to 150 meters) of highly anomalous PGE levels associated with chromite
and base metal sulfide often in pegmatoidal Ultramafic Series lithologies. To date, mineralization has seen
scout drilling only and remains open in all directions, emphasizing the underexplored nature of the ultramafic
portion of the Stillwater Complex. We are committed to further exploration of this iconic mining district and
believe in its potential to host significant new deposits.”
Including the new Hybrid Zone in the Chrome Mountain target area, Group Ten has identified a total of 14
multi-kilometer-scale target areas along the approximate 25-km strike length of the property (see Figure 1).
These 3- to 8-km-long target areas have been defined by major high-level electro-magnetic conductors with
broad coincident soil geochemical anomalies, and are further divided into eight ‘Platreef-style’ bulk tonnage
PGE-Ni-Cu sulphide target areas (blue ellipses) and six ‘Reef-type’ higher-grade PGE target areas (red ellipses)
including the Picket Pin PGE reef deposit.
The eight ‘Platreef-style’ bulk tonnage PGE-Ni-Cu target areas occur within the ultramafic and basal part of
the Stillwater Complex and are highlighted by strong electro-magnetic conductive signatures that are
characteristic of large bodies of massive to extensively disseminated sulphides. These geophysical targets have
overlapping highly elevated palladium, platinum, gold, nickel, copper, and chromium values in soils and rock
sampling. Individual target areas have from a few drill holes to as many as 30 wide-spaced holes that have
intercepted significant levels of platinum, palladium and gold along with nickel, copper, cobalt, rhodium,
vanadium and chromium.
The higher-grade ‘Reef-type’ PGE target areas at Stillwater West, occur both above and below Sibanye-
Stillwater’s J-M Reef deposit, which hosts a Measured and Indicated resource of 31 million ounces at a grade
of 17.0 grams per tonne (g/t) Pt+Pd, plus an additional 49 million ounces at 16.6 g/t Pt+Pd in Inferred
resources1, plus past production of 10 million ounces at similar grades2 from three active mines. Less work has
been completed on these Reef-type targets by Group Ten to date however surface sampling and drilling has
reported significant mineralization that will be assessed in future work.
2018 Exploration Programs
The 2018 exploration program, the Company’s first at Stillwater West, confirmed the potential of the Project
to host multiple large-scale, disseminated, polymetallic bulk tonnage deposits across the 25-km length of the
claim blocks. Work was focused on exploration of the lower Stillwater Complex where the Company sees the
potential for much larger mineralized systems than has been previously recognized in the district based on
geological similarities with the northern limb of South Africa’s Bushveld Complex, a region which hosts Anglo
American’s world-leading Mogalakwena PGE-Ni-Cu Mine, and Ivanhoe’s Platreef PGE-Ni-Cu project, which is
currently under construction.

14 large-scale (multi-kilometer) target areas identified across 25-km long property:
• Target areas presented above are defined by major high-level electro-magnetic conductors with broad coincident Pt+Pd+Au and
Ni+Cu+Cr+Co soil geochemical anomalies:
• Eight large-scale, bulk tonnage PGE-Ni-Cu +/- Cr sulphide target areas which may host Platreef-Style mineralization, each one
2 to 4 km long with potential for large-scale magmatic sulphide-hosted deposits
• Six higher-grade PGE ‘Reef-type’ target areas that are 3 to 8 km long which may host multiple ‘Reef-type’ deposits
• Data from more than 215 drill holes totaling over 28,000 meters from across the property confirms the presence of significant
intervals of platinum group elements (PGE) with nickel and copper sulphides in the target areas
• Geophysical and geochemical signatures show potential for a much larger mineralized system than has been previously
recognized; systematic drill testing has yet to be completed on these targets

Work was conducted in the following key areas at Stillwater West in 2018:
• Significant mineralized intervals from over 11,000 meters of core inventory were re-logged for assay
and the application of new geologic models from the Platreef. Re-logging is now complete, with assays
pending;
• Surface prospecting and rock sampling of mineralized outcrops along approximately 20 km of the 25-
km strike of the project was completed. Assay results are expected shortly;
• Detailed surface mapping of the Basal and Ultramafic Series covering an approximate 7 km2 area was
completed to augment the historical database and better define the stratigraphy of this underexplored
portion of the Stillwater Complex;
• Physical rock property measurements were completed on representative core and grab samples
including magnetic susceptibility, conductivity/resistivity, IP (Induced Polarization) chargeability, and
density. Rock property analysis is expected to be instrumental in developing new geologic and 3-D
models for the different types of mineralization at Stillwater West;
• Entry of all core data into the first property-wide 3D geologic database for modeling and target
refinement. This effort is ongoing, with results expected in 2019;
• Development of a predictive geologic model to drive future exploration efforts and follow-up drilling
(ongoing); and prioritization of all targets along the 25-km-long strike length of the Project (now
underway).
Next Steps
Results of the 2018 field program will be released in the coming weeks, with results of the greater modeling
and mapping efforts expected to be on-going through Q1 of 2019. Group Ten will attend both the Vancouver
Resource Investment Conference and AME Round Up trade shows in January, including core display at the
latter.
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 production2 and current M&I resources1, plus another 49 million ounces of Inferred resources1, 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 Complex3. 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.
