Drill Results

Sudbury Platinum intersects near surface Ni-Cu-Co-PGM mineralization at

Aer-Kidd

Sudbury, March 5, 2018 –Sudbury Platinum Corporation (“SPC”) and Transition Metals Corp. (XTM –

TSX.V, “Transition”, “the Company ”) are pleased to provide a project update and to announce assay

results from fall drilling completed at the company’s Aer -Kidd Project, near Sudbury Ontario. During a

period from N ovember to December the company completed eight holes for a total of 1,371m designed to

evaluate the up-dip and down -dip potential of the past -producing Rosen and Robinson Mines which are

located on the property adjacent to Vale’s producing Totten mine . SPC is a private company that is 36%

owned by Transition.

Highlights:

• AK-17-020 intersected 12.35m containing 0.91% Ni, 0.28% Cu, 0.03% Co and 0.80g/t PGM

(Pt+Pd+Au) from 70.55-82.90m including a higher grade section of 2.05% Ni, 0.17% Cu, 0.05%

Co and 1.03g/t PGM over 2.60m immediately up-dip of the past producing Rosen Mine.

• Borehole Geophysics in AK -17-025, testing down-dip of the past producing Robinson Mine ,

indicate strong previously untested offhole EM conductors proximal to areas of known historic

high-grade Ni-Cu mineralization (U9-E2: 28.7m @ 1.48% Ni, 0.61% Cu4).

Scott McLean, P.Geo., CEO of SPC stated, The near surface mineralization that includes significant

intercepts of PGM’s and cobalt is encouraging and demonstrates that we are continuing to explore a highly

prospective part of the Sudbury Igneous Complex. The property remains wide open at depths where

drilling on the adjacent properties has discovered world class deposits at Totten and Victoria.”

This release only discloses assay results fro m two holes, AK-17-018 and AK-17-020, completed during the

previously mentioned winter drill program. The remaining assays are pending. Figure 1 is a long section of

the property looking northwest that includes the pierce points of recent drilling.

Discussion of Results

Aer-Kidd Property

Located within the SW corner of the prolific Sudbury Basin the Aer -Kidd Property consists of a 1.4 km

section of the Worthington Offset Dyke (WOD). The WOD hosts several high -grade Ni-Cu-PGM deposits

including Vale's Totten Mine (10.1Mt @ 1.5% Ni, 1.97% Cu, 4.8g/t PGM )¹ located 1.8 km NE of the Aer -

Kidd Property and KGHM’s Victoria Project (14.5Mt @ 2.5% Ni, 2.5% Cu, 7.6 g/t PGM)² located 3.0 km NW

of the Aer -Kidd Property. On the property the WOD consists of a NW -SE trending, steeply dipping

composite dyke ranging in width from 40 to 70m. The dyke displays a distinct zonation in both inclusion and

sulphide contents from the margin to the core of the dyke.

Locally, the dyke contains a core of inclusion -rich quartz diorite (IQD), which can be choked with inclusions

surrounded by high-grade semi-massive to massive sulphide mineralization. The orebodies within the WOD

are primarily hosted within discontinuous phases of the IQD that contains 10 to 80 percent amphibolite

inclusions (AIQD) that can range in size from less than 10cm to greater than 10m in diameter. Zones of

AIQD form discontinuous lenses with in the center of the dyke that can range in size from a few 10’s of

metres up to 100’s of metres in length and width while the vertical extents of these zones can be greater

than 1,000 metres.

Past Production

The Aer-Kidd Property hosts three past produci ng Ni-Cu-PGM mines, the Howland Pit, Robinson Mine and

the Rosen Mine all of which are associated with pipe-like zones of AIQD. The Howland Pit was a small

open pit operation that was discovered in 1884 and produce <1,000 tons of high-grade ore. The Robins on

and Rosen Mines were discovered in the late 1880’s and were eventually put into production in 1966. Pre -

production reserves at Robinson were estimated at 497,744 tons 3 grading 0.62% Ni, 0.71% Cu (above the

800ft level) while at Rosen the reserves were e stimated at 274,560 3 tons at a similar grade. Production

lasted for three years period from 1966 to 1968 during which an estimated 462,743 tons 3 of ore were

hoisted from the two deposits with the bulk coming from the Robinson Mine.

Work to date

Since 201 4, SPC has completed 18,768m of drilling in 27 holes testing the property for geological

environments similar to those that host ed the Robinson and Rosen Mines. The majority of the drilling has

focused on testing the deep (>1,000m) down -dip potential of the Howland, Robinson and Rosen mineral

trends, focusing on areas of know n or interpreted AIQD, borehole geophysical anomalies and known

historic drill intersections. Drilling to date has identified three new areas of mass ive sulphide mineralization

up-dip an d down -dip of the past producing Ho wland, Robinson and Rosen Mines, as well, detailed 3 -D

geological modeling has identified three additional high-priority target areas requiring further exploration.

Howland Trend (down-dip)

Initial drilling was done to test a strong BHEM conductor that was identified in 2013 as part of the extensive

BHEM program that was completed across the property (see January 16 th, 2014 News Release). Initial

drilling intersected high -grade mineralization (see March 2 nd, 2015 News Re lease) within a thick and

extensive zone of AIQD. Highlights include AK -14-001A that intersected 8.1m @ 1.04% Ni, 0.75%Cu,

0.05% Co and 2.4g/t PGM from 900.8 -908.9m including a higher grade section of 2.47% Ni, 2.47% Cu,

0.12% Co and 10.18g/t PGM over 1.65 m. Drilling has outlined a 250m by 500m area of well-developed and

extensive AIQD containing numerous sulphide intersections as well many untested or partially tested EM

conductors that SPC feels remains to be fully evaluated.

Robinson Mine (down-dip)

Area was initially targeted to test for a potential down -dip extension to the Robinson Mine. Historic drilling

completed by Kidd Copper in 1968 returned 1.46% Ni, 0.6 1% Cu over 28.7m (U9-E2)4 approximately 150m

beneath the 95 0ft level of the Robinson Mine while Crowflight Minerals Inc. reported 1.4 2% Ni, 0. 62%Cu

and 1.76g/t PGM over 8.2 7m (W03-03AW1)5 approximately 500m beneath the 950ft level. In 2015, SPC

further tested this area with AK -15-003 and intersected 0.67% Ni, 0.99% Cu, 0.02% Co and 1.46g/t PGM

over 9.15m (see May 25 th, 2015 News Release). Mineralization within this area occurs as either Cu -rich

disseminated to blebby sulphides, as in AK -15-003, or as massive sulphides associated with well -

developed zones of AIQD, such as in W03 -03AW1. Borehole geophysical surveys in the area have

identified several high -conductivity anomalies that remain to be tested. As part of the 2017 winter drill

program, SPC completed hole AK -17-025 that was collared within the footwall to the Robinson Mine and

was designed to be a geophysical platform hole down to a vertical depth of 600m. The results of survey

indicate a strong offhole anomaly 25 to 50m down -dip of the intersections in hole U9-E2 and AK -15-003.

Drilling has outlined a 200m by 600m area extending from the b ase of the Robinson Mine of well-developed

and extensive AIQD containing numerous sulphide intersections as well many untested or partially tested

EM conductors that SPC feels remains to be fully evaluated.

Rosen Mine

Historical documents indicated that at the time of development (1966) the Rosen Mine was estimated to of

contained 274,560 tons of ore grading 0.62% Ni and 0.71% Cu (above 200m vertical). From 1967 to 1969

an undisclosed amount ore was extracted from the Rosen Mine on two main levels ( 350 and 650ft levels)

and one sub -level (500ft level). After a detailed review of the available mine sections and plans SPC

concluded that the bulk of the ore produced on the Aer -Kidd Property came from the Robinson Mine and

therefore potential existed for ore to remain in the ground at the former Rosen Mine. In the winter of 2017 ,

SPC drilled 554m in six holes to test for a possibly up -dip extension of the Rosen Mine as well as to assess

the overall potential of the past -producing Rosen Mine. Highlights of the program include AK -17-020 that

intersected 12.35m containing 0.91% Ni, 0.28% Cu, 0.03% Co and 0.80g/t PGM (Pt+Pd+Au) from 70.55-

82.90m including a higher grade section of 2.05% Ni, 0.17% Cu, 0.05% Co and 1.03g/t PGM over 2.60m.

Mineralization occurred as massive and semi -massive sulphides within a 23.0m thick zone of AQID that

contained >50% inclusions ranging in size from 0.2 to 2.55m in diameter. All of the remaining holes not

reported intersected smaller (typically <1m in core length) zone of massiv e and semi -massive sulphides.

SPC feels that the initial drill results up -dip of the Rosen Mine are positive and that further work should be

completed to fully evaluate the potential of the area.

Exploration Potential

Following a reinterpretation of the Aer -Kidd geological data, SPC has identified three high -priority target

areas between 750 and 2,000m vertical that are interpreted to represent the deep down -dip extensions of

the Howland, Robinson and Rosen mineralized AIQD trends. A newly recognized NW-SE trend SW dipping

normal fault has been interpreted to of offset the shallower portions of the AIQD trends by as much as 300

to 400m resulting in a repositioning of the down -dip extensions of the Howland, Robinson and R osen

trends. SPC intends on exploring these areas with diamond drilling and borehole EM surveys.
