Updated Feasibility Study for the Goose Gold Mine at the
100% owned Back River Gold District in Nunavut, Canada
March 2021
2 Forward Looking Information Statements relating to our belief as to the results of development studies, timing of receipt of necessary authorizations and licenses, the availability of project financing, the timing of the start of construction and the first gold pour, and the results of further optimization studies to the UFS, the potential tonnage and grades and contents of deposits and the potential production from and viability of Sabina’s properties are forward looking information within the meaning of securities legislation of certain Provinces in Canada. Forward looking information are statements that are not historical facts and are generally, but not always identified by the words “expects,” “plans,” “anticipates,” “believes,” “intends,” “estimates,” “projects,” “potential,” “opportunities,” and similar expressions, or that events or conditions “will,” “would.” “may,” “could,” or should occur. The forward looking information is made of the date of this presentation. This forward looking information is subject to a variety of risks and uncertainties which could cause actual events or results to differ materially from those reflected in the forward looking information, including, without limitation: the effects of general economic conditions; changing foreign exchange rates; risks associated with exploration and project development; the calculation of mineral resources and reserves; risks related to fluctuations in metal prices; uncertainties related to raising sufficient financing to fund the planned work in a timely manner and on acceptable terms; changes in planned work arising from weather, logistical, technical or other factors; the possibility that results of work will not fulfill expectations and realize the perceived potential of the Company’s properties; risk of accidents, equipment breakdowns and labour disputes; access to project funding or other unanticipated difficulties or interruptions; the possibility of cost overruns or unanticipated expenses in the work program; title matters; government regulation; obtaining and receiving necessary licenses and permits; the risk of environmental contamination or damage resulting from Sabina’s operations and other risks and uncertainties including those described in Sabina’s annual information form for the year ended December 31, 2019 available at www.sedar.com Forward looking information is based on the beliefs, estimates and opinions of Sabina’s management on the date the statements are made. Sabina undertakes no obligation to update the forward-looking information should management’s beliefs, estimates or opinions, or other factors, change, except as required by applicable law

Key Project Enhancements
This level of engineering significantly de-risks the Project, bringing a higher level of
certainty to capital and contingency estimates when compared to most feasibility studies
▪ An updated gold price of US$1,600/ounce and exchange rate of $C:US$ of 1.31:1.00
▪ 56% improvement on capital efficiency compared to the IFS (NPV/Initial CAPEX)
▪ Higher confidence in CAPEX and changes to project scope to de-risk execution & operations
▪ 1M of increase in reserve
▪ High-grade Umwelt underground earlier increases production profile (peak production of 312 koz Au in year 3)
▪ Process plant expansion from 3,000 tpd to 4,000 tpd at end of year two of production
▪ Echo open pit and underground, Goose Main underground, Llama underground added to mine plan
▪ No requirement for TSF, the most complicated and highest civil capital risk to the Project. Exhausted pits used for
tailings storage
▪ Pre-production mining at Echo and Umwelt pits place 2.2 Mt and 372K oz stockpiled material, prior to
commencement of milling operations (sufficient for two years of mill feed)
8
Key Project Enhancements Continued
▪ OP vs UG – 53%/47% (tonnes)
▪ Significant earthworks completed: box-cut for underground exploration ramp, 4 km of roads, airstrip extension,
and site prep for the process pad and accommodation complex
▪ Construction of Port and receipt of three sealifts successfully testing logistics and supply chain from the South
▪ Construction and operation of a 172km Winter Ice Road from the Port to the Goose Property, gaining valuable
experience in the Project’s key infrastructure
▪ Significant infrastructure including fuel tanks, batch plant, construction crushers and construction/mobile
equipment mobilized in 2019/2020 with two maintenance shops
▪ Basic engineering completed with detailed engineering substantially completed
▪ Constructability and operability review by third party Arctic construction team
▪ A prominent Original Equipment Manufacturer engaged to complete the process plant equipment design with a
fixed price contract
See slides 35,36 & 37 for QP information

UFS delivers a Project with a high degree of confidence compared to others
▪ The Project is fully permitted with no costly changes needed to accommodate future permitting requirements;
▪ The cost of Social License has been incorporated (IBA & Royalties);
▪ Detailed engineering is substantially complete based upon material take off quantities versus estimates and
factoring;
▪ Major logistics infrastructure and supply chain has been built and successfully tested;
▪ Substantial civil earthworks have been completed at Port and Goose Site;
▪ A third-party experienced Arctic contractor has provided a review on constructability and operability;
▪ Bonding amounts certain and agreed to by federal/Inuit Stakeholders and incorporated into the Project;
▪ Deliberate increase in CAPEX initiatives to provide lower operational/execution risk;
▪ Mineral Resource Estimates provide foundation for future reserves to extend mine life;
▪ Constructor has been involved in development of project schedule and resource loading;
▪ Framework for 3 year construction labour costs agreed to in principle;
▪ Additional capex has been allocated for operational readiness.
▪ Additional time for commissioning and ramp up has been added from IFS
