Sabina Gold & Silver Updates Progress For The Goose Mine Development: ~70% Procurement And 40% Overall Civil Works Completed

Press Release

May 16, 2022

VANCOUVER –Sabina Gold & Silver Corp. (“Sabina”) or (the “Company”) (SBB – TSX/ SGSVF – OTCQX) provides an update on advancements of the Goose Mine development at the Company’s 100% owned Back River Gold District in Nunavut, Canada. The Goose Mine is the Company’s first mine on the 80 km long Back River Gold District, a multi-generational mining district already with a high-grade world class gold endowment.

The first quarter of 2022 culminated in one of the most important milestones for the Company to date. Debt, streaming and equity financings were completed with a total of over C$800 million arranged, well in excess of the requirements of the 2021 Updated Feasibility Study (“UFS”).

More importantly, with financing in hand, pre-construction, logistical and procurement activities have accelerated. In anticipation of the financing, Sabina had prepared tender documents and purchase orders which enabled the Company to quickly procure critical components necessary for this year’s sealift.

The UFS CAPEX estimate was C$610 million. Of that, approximately C$218 million was identified as direct equipment and materials purchases. Since last year, Sabina has procured, or has committed agreements to procure, just over 70% of all direct purchases identified in the UFS. Reconciliation on purchases have seen an average overall inflationary escalation of 14% since March of 2021, with a 20% escalation on the purchases made in 2022. Efforts now focus on securing the remaining 30% (C$62 million) of materials and equipment.

Earthworks at the plant site are ~67% complete, which reflects an overall Project civil works completion rate of ~40%. To date, the Project is trending an ~10% quantity reduction from UFS estimates.

“Inflation and global supply chain issues have impacted all new capital investment projects and Sabina continues to monitor these potential impacts as we develop the Goose Mine,” said Bruce McLeod, President & CEO. “We are fortunate that our strategy of pre-planning and accelerating procurement efforts has reduced our exposure to inflationary impacts.”

Advancement Highlights and Schedule and Cost De-risking Events

Engineering

  • FLSmidth (“FLS”) has been chosen to supply the key equipment for the Goose Mine processing flowsheet. The equipment package is valued at approximately US$39 million and is due to be delivered by mid-2023, for implementation ahead of the mine start-up date of Q1, 2025;
  • CGT Industrial (“CGT”) has provided Sabina with a fixed priced proposal of C$130 million, with an agreed rise and fall mechanism, for materials and consumables for the process plant. These components make up approximately 85% of the direct works on site. The proposal is comparable to within 5% of the feasibility study estimate;
  • The team is preparing to move on to the design concept for the Echo open pit, which is intended to be pre-mined to enable initial tailings storage. The advanced mining of the Echo and Umwelt pits will also result in approximately two years of stock-piled feed for the mill prior to commencement of operations; and
  • Detail engineering is reaching 85% complete project wide with remaining engineering activities focused on vendor data updates as procurement activity progresses.

Procurement

Approximately C$157 million of C$218 million (72%) of materials and equipment required for the project (per UFS) has already been procured.

Purchased or committed items include:

  • 90% of mining fleet;
  • Entire process plant equipment at 4000 TPD;
  • Permanent accommodation complex (500 units) with kitchen and recreation center;
  • 95% of building envelope steel (by weight) and cladding;
  • 100% of project explosives required for construction;
  • Cranes and major construction support equipment;
  • 95% project cement & rebar – with concrete batch plant available on site;
  • 80% of secondary structural steel for the process plant and process piping;
  • 100% of all tailing, reclaim and freshwater piping for the project (~11.5Km of piping);
  • All conveyor galleries and arctic corridors;
  • Electrical E-houses complete with MCC and VFD (5 of 6 will be on 2022 sealift);
  • Electrical switch gear for the Powerhouse;
  • Water, sewer and waste systems;
  • HVAC unit and Dust collections systems;
  • Fuel dispensing and offloading system for Goose & Port sites;
  • All equipment for double heading winter ice road construction on site;
  • Fully functional aggregate crusher and washer unit on site;
  • 24 MW (N+2 configuration) Power plant cogeneration system with boilers and ancillary equipment from Toromont;
  • One ten-million and one five-million liter fuel storage tanks at each of Goose and Port sites, respectively; and
  • Liner requirements for all water management structures procured.

Sabina has approximately C$62 million remaining to be spent on procurement (based on the UFS) which will have exposure to the current inflationary environment. These items include:

  • Platework, pumps and tanks insulation -materials for which engineering is completed and quotes are being finalized;
  • Electrical bulks and cable tray;
  • Electrical miscellaneous equipment (process plant and powerplant);
  • PLC controls systems;
  • Instrumentation for the project; and
  • Communication systems.

Supply chain and Sealift

Supply chain resilience will continue to require expertise, novel solutions and strong collaboration among Sabina and its suppliers. Key strategies include diversification of suppliers, monitoring production capabilities and transportation processes, as well as finding alternative materials and nontraditional partnerships. To this end, Sabina has implemented the following:

  • Ensuring dedicated internal resources, including specialized expeditors, to monitor progress on fabrication of equipment procured;
  • Co-ordinating with CGT during the procurement phase of all critical fabrication items to de-risk the construction schedule at site;
  • Reviewing fuel supply proposals for 2022 sealift;
  • Securing sealift carriers at both East and West transport/consolidation points for the 2022 sealift program; and
  • Completing the installation of a fully functional hard wall camp at Port to support activities in 2022.

Although supply chain issues have impacted delivery dates, through advance planning, all major equipment required is anticipated to arrive in time for this year’s sealift.

Civil Works & Logistics

Considerable pre-development activities have already been completed at the Goose and Port sites. This work includes:

  • ~40% of overall project and ~67% of plant site civil works;
  • Construction of two 10 million-liter fuel tanks constructed (Port and Goose);
  • ~20km of all weather roads completed at Project;
  • Pads complete for permanent camp, plant and fuel storage;
  • Approx. 25,000m2 of additional laydown area created at the Port;
  • New hard wall camp at Port and forward camps established;
  • Esker harvesting and placement for sub-base prep along winter ice road route to improve future construction campaigns; and
  • 700 meters of underground exploration ramp completed at Umwelt.

With surface construction season commencing, Sabina is preparing to mobilize crews to further advance civil works on site. Budgeting and scheduling is nearing completion and will be announced in the coming weeks.

Planning is well underway for the marshalling of procured equipment and supplies, at both East and West transport locations, for the 2022 sealift campaign in the late summer of this year.
