Group Ten Metals Announces Priority Targets at the Iron Mountain Area

of the Stillwater West Project, Including Cobalt Zone

May 8, 2018 – Vancouver, BC - Group Ten Metals Inc. (TSX.V: PGE; US OTC: PGEZF; FSE: 5D32) (the “Company”

or “Group Ten”) is pleased to announce th e results from compilation and interpretation work focused on the

Iron Mountain area of the Company’s Stillwater West project in Montana , including the delineation of a large

cobalt target defined by highly elevated cobalt in soils and corresponding rock samples.

Work to date at the Stillwater West project has identified two broad target types – large-scale “Platreef-style”

mineralization and higher-grade “Reef-type” deposits – with 12 broad target areas across the more than 20

kilometre ( km) long main claim block, plus three satellite blocks w hich contain additional zones of interest .

Compilation and analysis by Group Ten shows the potential for multiple deposits and indications of a much larger

mineralized system than has been previously recognized. Of particular focus are those areas that show

characteristics of a “Platreef-style” setting in the lower Stillwater Complex stratigraphy that may be similar to

the large-scale high-sulphide PGE-nickel-copper type deposits seen in the lower Bushveld Complex in South

Africa1.

Three of the five identified zones in the Iron Mountain area are large-scale, high-sulphide PGE-nickel-copper

targets that are a priority for additional work based on the magnitude of the coincident geochemical and

geophysical conductor anomalies (see news releases from January 10 and F ebruary 26, 2018). As shown in

Figure 1, these three broad, conductive anomalies overlap with highly elevated platinum group elements, nickel,

copper and chromium values in soils across the entire 8km length of the Iron Mountain area. These targets have

been further prioritized due to the confirmation of significant PGE -Ni-Cu mineralization in drilling, mostly from

the 1970’s, that partially tested these areas for nickel and copper sulphides . The Company is currently

completing a systematic re -logging of existing core and reviewing detailed core logging records in order to

develop a predictive geologic model to drive future exploration efforts and follow-up drilling.

The Company also reports that it has identified elevated cobalt values in soil and rock samples covering an area

of more than 2.7km by 1.1km (see inset, Figure 1) that correlate closely with nickel values, including:

• Consistently high cobalt values in soil of 75 to 220 ppm Co; and

• rock samples with assays up to 0.14% Co in 155 samples with a cut-off of 0.005% (50 ppm).

Large magmatic PGE-Ni-Cu deposits, including the Bushveld, are commonly recognized to contain cobalt 2, and

generally produce cobalt as a by-product of nickel and copper production. Recognition of potentially significant

cobalt grades at Stillwater West may be an important additional element of value as the company continues

exploration on these polymetallic targets within the lower Stillwater Complex.

President and CEO Michael Rowley stated, “We are very pleased with the continued progress of our compilation

and interpretation work starting with the Iron Mountain area. We believe that our systematic approach to

evaluating this under-explored part of the Stillwater Complex can result in substantial new value-creating

discoveries, especially in light of the advancements in understanding of similar settings such as the Bushveld in

South Africa. The recognition of the potential for significant cobalt at Stillwater West, within the United States,

is an exciting development which expands our exposure in the technology and battery materials space at a time

when sources from the developed world are increasingly desirable and the US Government has defined cobalt

as a ‘critical commodity’. We look forward to providing further technical releases from the Iron Mountain target

area and other target areas at Stillwater West, as part of our 2018 exploration program, in the coming weeks.”

Upcoming Events

The Company will be attending the 121 Mining Investment conferences in London, UK on May 17 and 18, and

New York City on June 5 and 6, in addition to hosting guided web tours in the coming weeks. Interested parties

are invited to contact the Company for more details.

Forward Looking Statements: This news release includes certain statements that may be deemed "forward-looking statements". All

statements in this release, other than statements of historical facts including, without limitation, statements regarding potential

mineralization, historic production, estimation of mineral resources, the realization of mineral resource estimates, interpretation of prior

exploration and potential exploration results, the timing and success of exploration activities generally, the timing and results of future

resource estimates, permitting time lines, metal prices and currency exchange rates, availability of capital, government regulation of

exploration operations, environmental risks, reclamation, title, and future plans and objectives of the company are forward-looking

statements that involve various risks and uncertainties. Although Group Ten believes the expectations expressed in such forward-looking

statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or

developments may differ materially from those in the forward-looking statements. Forward-looking statements are based on a number

of material factors and assumptions. Factors that could cause actual results to differ materially from those in forward-looking statements

include failure to obtain necessary approvals, unsuccessful exploration results, changes in project parameters as plans continue to be

refined, results of future resource estimates, future metal prices, availability of capital and financing on acceptable terms, general

economic, market or business conditions, risks associated with regulatory changes, defects in title, availability of personnel, materials

and equipment on a timely basis, accidents or equipment breakdowns, uninsured risks, delays in receiving government approvals,

unanticipated environmental impacts on operations and costs to remedy same, and other exploration or other risks detailed herein and
