December 3, 2020 Fredericton, New Brunswick - Northcliff Resources Ltd. ("Northcliff" or the "Company") (TSX: NCF), on behalf of Sisson Mines Ltd., is pleased to announce that the Minister of the Department of Environment and Climate Change ("DECC") has approved a two-year extension of the construction commencement timeline for the Sisson Mine Project to December 3, 2022.

"On behalf of Northcliff, we wish to thank the DECC for their co-operative approach towards the development of the Sisson Tungsten-Molybdenum Mine Project ("Sisson Mine") during these unprecedented and challenging times due to the COVID-19 pandemic" said Andrew Ing, Northcliff Interim CEO.  "The proposed Sisson Mine is a significant asset for the critical mineral1 tungsten -- an essential ingredient to modern economies and emerging technologies that has few substitutes and could face high supply risks."

Earlier this fall, the review of Sisson Fisheries Act Authorization application and Off-setting/Fish Habitat Compensation Plan was completed and approved. Pursuant to paragraph 35(2)(b) of the Fisheries Act the Minister of Fisheries and Oceans Canada has authorized the proposed work that will result in impacts to fish and fish habitat arising from the construction and operation of an open pit and tailing storage facility that will result in impacts to fish and fish habitat.

The Sisson Mine Project received Environmental Impact Assessment ("EIA") approvals from the provincial and federal governments in 2015 and 2017, respectively, and successfully completed the Metal and Diamond Mining Effluent Regulation Schedule 2 amendment ("MDMER") authorization process in July 2019. A Cooperation Agreement between Woodstock First Nation and Sisson Partnership is in place and the Province of New Brunswick has signed an Accommodation Agreement with the six Maliseet First Nations of the province.
