NorZinc Ltd. provided an update on activities at the Prairie Creek Project ("Prairie Creek" or "the Project") located in the Northwest Territories, Canada. The Company announced that the amendment to the mine Water License ("WL") and Land Use Permit ("LUP") for the expansion from 1,600 tpd mining to 2,400 tpd mining has continued to move through the regulatory process and that the draft WL and LUP were distributed for comment on April 14, 2022. A final decision by the regulatory authority, the Mackenzie Valley Land and Water Board ("MVLWB"), is expected for the LUP with issuance in June 2022, along with a recommendation for the approval of the WL by the Government of the Northwest Territories Minister of Environment and Natural Resources to be undertaken within 90 days of the recommendation.

The Company has also made progress throughout 2022 working with the regulatory authorities, Parks Canada ("Parks") and the MVLWB, to clarify the additional requirements and advance the conditions of the license and permit to commence construction of the Phase 1 All-Season Access Road ("ASR"), also known as the Pioneer Winter Road ("PWR"). In particular, the Company and Parks have established a regular meeting schedule and are working closely to meet the necessary permit conditions and comply with all regulatory guidelines to a high standard. In November 2019, NorZinc received the necessary authorizations to construct, maintain and operate an ASR from Liard Highway to the Project from the appropriate regulatory authorities, including MVLWB and Parks.

Specifically, the authorizations received were the WLs and LUPs for the ASR. Conditions of the WLs and LUPs for the ASR include the completion, review and approval of various management plans ("MP") by the MVLWB and Parks. The company has been focusing efforts on the completion of these MPs for the Phase 1 ASR and as of this date, the Company received final or conditional approvals on over 70% of the MPs and is expected to complete all Phase 1 MP approvals by mid-year. Based on the continuous progress and ongoing engagement with the regulatory authorities it is the Company's expectation that final management plans approvals will be received by Third Quarter 2022.

Based on this timeline, the Company plans to commence construction of the PWR in Fourth Quarter 2022, when temperatures and conditions are suitable to start the required work. The PWR constitutes Phase 1 of the ASR which will be the first road access to the mine in over 40 years.
