Canadian Gold Miner’s Option Partner IAMGOLD Obtains 5.5 g/t Gold over 3.3 metres from

Channel Sample Results at Jumping Moose

Sudbury, June 5 , 201 8 – Canadian Gold Miner (“CGM” or “the Company ) and Transition Metals Corp.

(“Transition Metals”, XTM.V) are pleased to report results from channel sampling completed on the Jumping

Moose property by option partner IAMGOLD Corporation ( “IAMGOLD”). Assay results from this work initiated

by IAMGOLD in late 2017 returned gold values from channel samples ranging from nil to 22.7 g/t gold including

5.50 g/t gold over 3.3 metres from a new trenched bedrock exposure of sheared gabbro hosting quartz veining

and disseminated sulphides.

Table 1 presents a summary of the results of this work.

Greg Collins, president and CEO of Canadian Gold Miner states, “We are encouraged by the results at

Jumping Moose. The elevated gold, silver and tellurium values are consistent with those observed in the

nearby boulder field in a manner that supports a thesis that the high grade boulders could have been derived

from the newly discovered bedrock source. We look forward to results from additional work on the property

planned by IAMGOLD over the summer.”

Discussion of Results

Historical work on the Jumping Moose property has sought to identify the source of a cluster of large angular

and extremely high grade gold -silver-tellurium bearing quartz vein boulders found on the east side of Jumping

Moose Lake in the 1950’s . The bedrock source of th ese boulders was presumed to be north based on

conventional assumptions for the region regarding ice transport directions . Recent glacial geology work

completed by the Ontario Geological Survey in the area now identifies that the last glacial transport direction at

Jumping Moose may have been oriented towards the west as opposed to the south. This implies that a

bedrock source for the boulders may be to the east of the cluster as opposed to being located to the north as

was previously thought.

In the 1980’s and 90’s, mineralized bedrock occurrences were discovered on the property near the western

shore of Jumping Moose Lake and along an east by northeast shear id entified 800 metres to the east,

immediately south of the high grade boulders. Diamond drilling on the east side of the lake targeting this shear

intersected narrow zones of sheared quartz veining with sulphides returning up to 6.9 g/t gold over 1.1 metres

(Argentex 1987) and more recently 4.76 g/t gold over 0.5 metres (Abalor 2013).

Prospecting during the fall of 2017 by IAMGOLD in an the area immediately east of this structural trend in the

vicinity of an anomalous induced p olarization ( IP) chargeability response returned an anomalou s gold grab

sample (2.72 g/t Au). This new target area was observed to occur along the same trend as the historical drill

intersections in a position that could be a prospective source area for the boulder cluster.

To test this hypothesis, IAMGOLD excavated a trench to expose bedrock in the vicinity to the elevated grab

values and to explain the associated IP chargeability anomaly. Assay samples this work returned significant

gold values including 5.50 g/t gold over 3.3 metres. The results from the trench channel sampling confirm the

discovery of a new high grade bedrock gold occurrence in a location that could be the long sought after source

area for the cluster of exceptionally high grade boulders.

Next Steps

IAMGOLD ha s confirmed its intent to maintain its options on both the Jumping Moose property as well as

another CGM property, the Elephant Head property into 2019 and is considering additional work on both

properties including additional trenching, focused geophysical surveys and drilling.

The Jumping Moose project

The Jumping Moose project is one of two projects (Jumping Moose and Elephant Head) optioned to IAMGOLD

by CGM in February of 2017 (see news release dated March 3, 2017) approximately 50 kilometres northeast of

IAMGOLD’s Côté Gold deposit near Gogama. The Jumping Moose property is underlain by volcanic rocks of

the southern part of the Abitibi Belt in an area thought to host a potential southwest extension of the prolific

Cadillac-Larder Lake Deformation Zon e (“CLLDZ”). The stratigraphy includes amphibolite grade massive and

fragmental metavolcanic rocks, with highly deformed interflow chemical and clastic meta -sediments and

intruded by ultramafic to mafic sills and late NW-trending diabase dykes.

Under the t erms of the option and joint venture agreement, IAMGOLD can earn a n initial 51% interest by

incurring $850,000 of expenditures and paying CGM $80 ,000 in cash over 3 years, with an option to increase

up to an 80% interest by incurring an additional $2,000,000 in expenditures and making additional $250,000 in

cash payments to CGM over 2 years following the initial 51% interest earn in. Upon earning a 51% or 80%

interest, as the case may be, the Option will convert to a joint venture with each party pro viding funding to

maintain its proportionate interest or be diluted down. Should a party be diluted to 10% or less, its interest

would be converted to a 2% NSR. The Jumping Moose property remains subject to an underlying 2% NSR to

the original land holder and a $1,000,000 commercial production payment to Transition Metals.

QAQC

All channel samples were collected in the field by trained personnel working for IAMGOLD following standard

industry practice and sent to AGAT Laboratories in Mississauga Ontario, a certified laboratory that conforms to

ISO 17025 standards. Samples were dry crushed until 90% passing 2 mm, split to 250 g, and pulverized until

85% passed 75 microns. Material was analyzed for a multi-element four acid digestion ICP/method. Gold

analyses were determined on a 30 gram aliquot by fire assay with an atomic absorption spectrometry finish. All

samples that returned >10 g/t Au were re-analyzed using a metallic screen that involved the complete analysis

of a 500 g aliquot with the gold determined by fire assay with a gravimetric finish.
