Marathon Gold Provides Update on Development Plans for the Valentine Gold Project

TORONTO, April 12, 2022 (GLOBE NEWSWIRE) — Marathon Gold Corporation (“Marathon” or the “Company”; TSX: MOZ) is pleased to provide an update on development planning for the Valentine Gold Project located in the central region of Newfoundland and Labrador (the “Project”). In this news release, Marathon is providing guidance on remaining regulatory approvals and permitting, the Project’s execution strategy and schedule, mineral resources and mine planning, capital and operating cost outlook, and project financing. Highlights are as follows:

  • Provincial Environmental Assessment (“EA”) completed. Federal EA approaching a ministerial decision. Site-specific permitting commenced.
  • Subject to this regulatory schedule, site early works to commence in the third quarter, supporting full site mobilization by the end of the year and first gold pour in late 2024.
  • Updated Mineral Resource estimate (“MRE”) to be completed by mid-year, incorporating the 2021 Reverse Circulation (“RC”) drilling at the Marathon and Leprechaun Deposits and 100,000 metres of exploration drilling at the Berry Deposit. An overall increase in open-pit Measured plus Indicated Mineral Resources is anticipated.
  • Life-of-mine capital and operating costs are estimated to have increased by between 15% and 20% compared to the April 2021 Feasibility Study, in line with market trends.
  • New technical report to be prepared for the fourth quarter of this year, incorporating the new MRE, new production schedule, updated capital and operating costs, and higher gold price environment.
  • US$185 million term loan credit facility closed and available for draw in alignment with Marathon’s project development strategy.

Matt Manson, President and CEO, commented: “Following the recent provincial Cabinet approval of the Valentine Gold Project, and the closing of our US$185 million term loan credit facility, we are providing guidance today on the development path for the Project for the remainder of this year and into principal construction. Upon the receipt of final regulatory approvals and site permits we intend to start early works activities in the third quarter of this year. This will support a schedule for first gold production in late 2024. At the same time, we will work to complete a new technical report and production schedule for the Project, for release later this year. This will incorporate a new project-wide mineral resource estimate, the most robust completed to date, that is expected to show an estimate of open-pit Measured plus Indicated Mineral Resources that is both larger and better constrained. The new technical report will also reflect the impact of both the higher capital and operating cost environment on the Project and the higher gold price environment. The net result of this program of work will be a Project permitted for construction, with site development activities underway, and a new longer-term vision for Atlantic Canada’s largest gold mine.”

Environmental Assessment and Permitting

On March 17, 2022, the Project received approval by the Cabinet of the Government of Newfoundland and Labrador, marking the completion of the provincial EA process. This has allowed Marathon to commence permitting for site activities pertaining to provincial jurisdiction, including the acquisition of the Project’s Mining Lease.

Concurrently, Marathon received formal notification from the Impact Assessment Agency of Canada (“IAAC”) overseeing the federal EA process that it had completed its technical review of the Project’s Environmental Impact Statement. This allows IAAC to complete and issue a draft EA Report for the Project, which will be available for public comment for 30 days. This is expected shortly. On the completion of this review period, the Minister of Environment and Climate Change Canada will be in a position to make a determination on the acceptability of the Project for development. Approval either directly by the federal Minister or, if he directs, in federal cabinet, would represent the completion of the federal EA process and allow permits to be acquired on site activities pertaining to federal jurisdiction.

Marathon anticipates completion of the federal EA process and the receipt of sufficient permits to allow site construction activities to commence in the third quarter of this year, as per previous guidance.

Execution Strategy and Schedule

2022 third quarter site activities are expected to include the upgrading of the Project’s access road and bridges from Millertown, construction of a 120 bed temporary construction camp, tree cutting and grubbing, pad development, and the installation of communications infrastructure. Mine pre-development at the Leprechaun Deposit will commence concurrently to provide construction materials. The Project’s main accommodation camp, which was purchased in 2021, is expected to be installed before the end of the year along with temporary workshops and warehousing. Once these early works have been achieved, principal site mobilization for the construction of the mill, major facilities, and the Tailings Management Facility will commence by the end of the year. This schedule supports first gold pour by the end of 2024. Full site mobilization will be subject to a construction decision by the Board of Director’s following the receipt of all regulatory approvals.

Project execution will be by way of an integrated team of specialized contractors under the overall management of Marathon’s project development team based in Grand Falls-Windsor, NL. Contracts for engineering, procurement and construction management roles are expected to be finalized shortly. Marathon will not proceed with a fixed price Engineering, Procurement and Construction contract (commonly referred to as “EPC”) for the Project’s mill and major facilities, as was previously guided. Marathon believes an integrated team strategy provides an overall lower risk approach in the current construction environment, and allows for better site coordination, initiative on potential cost and schedule efficiencies and, ultimately, better project delivery.

Mineral Resources and Mine Plan

During 2021 Marathon completed an approximately 12,000 metres RC drill program at the Leprechaun and Marathon Deposits, and completed approximately 70,000 metres of new exploration diamond drilling at the Berry, Victory and Sprite Deposits.

The 2021 RC drill program was undertaken to test the Project’s Mineral Reserve block model within the Phase 1 pits of the Project’s mine plan (see Marathon news release dated February 23, 2022). The program gave good insight into areas of the block models that may be variously understated or overstated in gold content. It also provided strong confidence in the continuity and orientation of the Quartz-Tourmaline-Pyrite-Au veins that host the Project’s gold mineralization.

The 2021 exploration program was focussed principally on in-fill drilling at the Berry Deposit. An April 2021 maiden mineral resource estimate at Berry comprised 638,700 oz of Inferred Mineral Resources (11.33 Mt at 1.75 g/t Au) based on approximately 42,000 metres of drilling completed to the end of November 2020 (see Marathon news release dated April 21, 2021). By the end of November 2021 approximately 100,000 metres of drilling had been completed over the full 1.5 kilometres of the Berry Deposit’s length. Fire assays for approximately 93,000 metres of this drilling have been received and published, with the final data expected to be released shortly.

These new RC and diamond drilling data will be incorporated into a new MRE for the Project by mid-year. The estimate will be based primarily on metallic screen fire assays, as with previous convention, and utilize new, better constrained geological models for each deposit. Marathon expects that this work will result in an increase in the quantity and confidence of Mineral Resources at the Berry Deposit. At the same time, tighter constraints on the modelling of mineralised volumes prompted by the 2021 RC work is expected to result in a decrease in tonnes and ounces at the Marathon Deposit. Minimal changes are expected at the Leprechaun Deposit. At present, and subject to the completion of the MRE, the aggregate result of this work is expected to be an increase in the overall quantity of open pit Measured plus Indicated Mineral Resources and a decrease in Inferred Mineral Resources at the Project.

Following the MRE work, Marathon will complete a new NI 43-101 technical report for the Project, which will constitute an updated Feasibility Study (the “Updated FS”). This will reflect the updated MRE, an updated production schedule, the development schedule, and the current capital and operating cost environment. Marathon will also re-assess the optimum pit size for each deposit in the light of a sustained higher gold price environment since the pits were first designed in 2020. No changes are expected in processing and facilities design, infrastructure, mining methodology or tailings deposition strategy. The Updated FS is expected to be completed by the fourth quarter of the year.

Capital and Operating Cost Outlook

The Project’s April 2021 Feasibility Study (“FS”) estimated an initial capital cost of C$305 million, total life-of-mine (“LOM”) capital costs of C$662 million, total cash operating costs of US$704/oz and all-in sustaining costs (“AISC”) of US$833/oz. Since this time significant cost inflation and construction market volatility has impacted major capital projects globally. Based on the Project’s current scope and development timeline, Marathon forecasts that LOM capital costs at the Project will be between 15% and 20% higher than previously estimated principally due to higher materials costs and contractor rates. Cash operating costs and AISC are similarly estimated to be approximately 15% and 20% higher, principally due to higher consumables costs and labour rates. The April 2021 FS financial analysis (as well as the underlying estimates for Mineral Resources and Mineral Reserves) utilized a gold price assumption of US$1500/oz and a US$:C$ exchange rate assumption of 0.75. The Updated FS will contain a re-estimate of the Project’s capital and operating costs, and a gold price and exchange rate assumption reflecting the current market. Marathon also intends to re-characterize certain capital costs that were previously captured as early sustaining capital items to initial capital cost. This will increase the initial capital cost but reduce AISC and de-risk the Project’s ramp-up to positive cash-flow.

Project Financing

Marathon announced the closing of its US$185M term loan credit facility with Sprott Private Resource Lending II (Collector-2) LP (the “Facility”) on March 31, 2022. The proceeds of the Facility are to be used for the Project’s development costs and working capital requirements. The balance of the Project’s construction costs, working capital requirements, overrun funding provisions, corporate and financing costs, and exploration costs will be funded from existing cash reserves and new equity. At March 31, 2022, Marathon had cash and cash equivalents of approximately C$73 million.

Other than the Facility and equity funding, Marathon does not contemplate completing any additional debt, royalty, streaming, or gold offtake arrangements to finance the Project. An existing 2% net smelter returns royalty is held by Franco-Nevada Corporation, with a right in Marathon’s favour to repurchase 0.5% for US$7 million before December 31, 2022. On March 14, 2022 Marathon announced the purchase for cancellation of a 7.5% net profit interest royalty on certain mineral resource areas of the Project from the Reid Newfoundland Company Limited. Equipment-lease carve outs of approximately US$110 million are permitted under the terms of the Facility, and will be used to finance mobile and drilling equipment during the life of the Project.
