Klondike Provides Update on Upgrades to Tailings Management Facility

May 27, 2021 - Vancouver, Canada – Klondike Silver Corp. (“Klondike Silver” or the “Company” )

(TSX.V: KS) is pleased to provide an up- date on the significant progress being made on remedial

measures to its Tailings Management Facility (“TMF”) in Sandon, British Columbia. As noted in

Klondike’s press release of February 26, 2021, the Company received notification from the Chief Gold

Commissioner for British Columbia that its Free Min er Certificate (“FMC”) had been cancelled. The

FMC is required in order for the Company to continue with underground exploration and development of

its Silvana underground mine property. The cancellation of the FMC resulted from a culmination of a

number of outstanding non-compliance issues associated with the Company’s TMF. The current TMF is

comprised of three distinct tailings ponds that are abutted against each other and are adjacent to

Carpenter Creek.

The Company is permitted to apply for renewal and reinstatement of the FMC once the following

conditions have been fulfilled:

• A 2020 Dam Safety Inspection report is to be completed, signed and sealed by a professional

engineer prior to the end of March 2021. THIS HAS BEEN COMPLETED . Klondike Silver

submitted to the Ministry of Energy Mines and Low Carbon Innovation (“EMLI”) the 2020 Dam

Safety Inspection (DSI) report (signed and sealed by a professional engineer) prior to the end of

Q1, 2021.

• A Geotechnical Site Investigation factual report and geotechnical assessment is to be completed

signed and sealed by a professional engineer. THIS IS IN PROGRESS. Tetra Tech Inc. (“Tetra

Tech”), a geotechnical and engineering consulting firm, has been commissioned to complete this

report with a target date for completion of August 2021. Tetra Tech has already completed a drill

program on the TMF to examine the embankments of all three tailings ponds, the tailings material

within the ponds and the characteristics of the subsurface of the TMF. As outlined in the

Company’s press release of April 19, 2021, Tetra Tech installed piezometers in the drill holes to

measure the depth of groundwater within the TMF throughout the year.

• An Erosion Protection Plan and an Erosion Protection As -Built Report is to be completed, signed

and sealed by a professional engineer. THIS IS IN PROGRESS . Tetra Tech has been

commissioned to complete this plan and report with a target completion date of September 2021.

The Protection Plan is expected to include armouring of the banks of Tri butary Creek and

Carpenter Creek through the placement of “rip- rap” or large loose rock, re- sloping of the

downstream angle of #3 dam and development of a catchment at the bottom of Tributary Creek to

provide surge capacity. In addition, the Company secure d approximately 1,000 tonnes of rip- rap

material for emergency use during the 2021 spring freshet. The 2021 spring runoff has not been

as extreme as 2020 and the Company does not expect to need to place this material.

As further background, the Company wa s in the process of remedying the non- compliance issues

identified above, when in April 2020 the Sandon mill and surface facilities received an in rush of water,

sediments and trees from upper Tributary Creek which originates above the facilities and captu res water

from the Idaho Peak watershed. Tributary Creek joins Carpenter Creek with the confluence of the creeks

meeting in close proximity to the three existing TMF structures and the mill. The volume of water and

sediments represented a 200- year flood event which exceeded the capacity of Carpenter Creek and

resulted in some erosion of the base of #3 Tailing Storage Facility (“ TSF”). Repairs to #3 TSF were

completed in June 2020. Klondike Silver is not responsible for maintenance of the access roads above

the mill location but based on the 2020 freshet Klondike Silver has committed to taking measures to

mitigate a similar result by taking pro-active measures in proximity to Carpenter Creek.

Klondike Silver and Tetra Tech continue to work closely with t he EMLI to ensure that the that the non-

compliance issues are remedied . The Company will provide a further update on progress by the end of

Q2 2021.

The scientific and technical disclosure in this news release has been reviewed and approved by David

Makepeace, P.Eng., Senior Geologist – Environmental Engineer at Geospectrum Engineering, who is an

independent consultant to the Company and Qualified Person as defined in NI 43-101.
