BOREALIS MINING ANNOUNCES ACQUISITION OF GOLD BULL RESOURCES

Borealis Mining Company Ltd. and Gold Bull Resources Corp. have entered into a definitive agreement signed on Dec. 9, 2024, whereby Borealis will acquire all of the issued and outstanding shares of Gold Bull, pursuant to a plan of arrangement, adding high-margin ounces in Nevada to Borealis's future gold production profile on its goal to become a mid-tier gold producer.

Transaction highlights:

• The transaction delivers to Borealis shareholders a highly advanced and robust Nevada gold project with a low capex and extremely high IRR (internal rate of return) and NPV (net present value), particularly at today's gold prices, that adds to Borealis's future production profile.
• The transaction delivers to Gold Bull shareholders a significant premium with an acquisition price of approximately 60 cents per Gold Bull share or a ratio of 0.93 Borealis share for each Gold Bull share, based on a 20-day volume-weighted price average.
• The Borealis mine and Sandman projects are synergistic in that the Borealis ADR (adsorption, desorption and recovery) facility can be used to process loaded carbon from the Sandman project as proposed in the 2023 PEA (preliminary economic assessment), which dramatically lowers capex and permitting risks.

Kelly Malcolm, chief executive officer of Borealis, stated: "We have been very interested in Gold Bull and, in particular, the Sandman project for many months now. Our team has internally validated both the existing 2021 mineral resource and the economics presented in the 2023 PEA, and have seen potential near-term upside opportunities in both. The Sandman project benefits from a great location close to Winnemucca, Nev., strong historical and recent metallurgical results, a massive historical data set, and robust proximal infrastructure. We look forward to rapidly advancing the project to production, especially in light of the sensitivity analysis of the 2023 PEA, which shows very exciting economics at current gold prices. Next steps will be validation of historical metallurgical results, which indicate non-refractory and readily recoverable gold mineralization, initiation of a feasibility study, and concurrent permitting. We hope to welcome existing Gold Bull shareholders to the Borealis journey, pending completion of the transaction, as we seek to grow into an established Nevada-focused gold producer."

Cherie Leeden, CEO of Gold Bull, stated: "We reviewed and analyzed numerous companies for potential mergers, and, of those, Borealis stood out to us as the ideal partner. The Borealis board boasts extensive experience in planning, financing, building and operating mines. The merger allows our shareholders to maintain exposure to our Sandman and Big Balds projects through a meaningful ownership stake in the combined company while gaining exposure to the Borealis mine, which is a fully permitted and near-term producing gold asset, also located in Nevada. We are convinced that combining forces with Borealis will unlock significant value for all shareholders, as Borealis has committed to advance the Sandman project through to feasibility study with the aim of getting Sandman into production as soon as possible. The intended outcome is to build the combined entity into a mid-tier gold producer. Today represents a significant milestone for all Gold Bull stakeholders and I would like to thank them for their support over the years, during a difficult period in the junior gold market."

Benefits to Borealis shareholders:

• Acquisition of an advanced PEA-level project in Nevada at a cost of $14.6 (U.S.) per indicated ounce (oz) of gold. Adds 433,000 indicated and 60,800 inferred gold ounces to the Borealis portfolio;
• The current (2023) Sandman PEA envisions a low initial capex ($31.5-million (U.S.)) operation with an IRR of 81 per cent (posttax) and NPV of $121-million (U.S.) (posttax discount rate of 6 per cent) delivering an average annual gold production of 37,900 oz of gold and average annual free cash flows (posttax) of $22.9-million (U.S.), at a price of $1,800 (U.S.) per oz of gold;
• The PEA envisions a scenario where a simple heap leach operation is built at Sandman and loaded carbon is shipped to an external ADR facility to process into dore bars. The Borealis ADR facility is fully permitted and fully equipped to process external carbon, thus resulting in the low projected capex;
• Internal review of the Sandman resource model and economic scoping study shows immediate upside opportunities;
• Large and underexplored Sandman land package provides exploration upside opportunity with a number of untested geophysical and geochemical targets;
• Additional Big Balds project provides an early-stage exploration project proximal to the Bald Hills gold mine near Elko, Nev.

Benefits to Gold Bull shareholders:

• Immediate and significant upside for Gold Bull shareholders with an acquisition price of approximately 60 cents per Gold Bull share, representing a significant premium of 86.3 per cent to Gold Bull's 30-day VWAP (volume-weighted average price) and 71.1 per cent to the 90-day VWAP;
• Share ratio of 0.93 Borealis share for each Gold Bull share, based on a Borealis 20-day VWAP;
• Meaningful ownership in the combined entity providing continued exposure to Sandman and Big Balds, as well as to Borealis's fully permitted Borealis mine;
• Increased trading liquidity, capital markets presence and enhanced combined value proposition;
• Near-term revenue generation from the Borealis mine may limit future dilution;
• Combined entity creates increased financing options to advance Sandman to production.

Transaction details

Pursuant to the transaction, each common share in Gold Bull will be acquired and exchanged for 0.93 Borealis common share, resulting in the issuance of approximately 13.8 million Borealis shares. Upon completion of the arm's-length transaction, existing Borealis and Gold Bull shareholders will own approximately 86 per cent and 14 per cent of Borealis, respectively. There are no finders' fees payable pursuant to the transaction.

The transaction will be completed pursuant to a court-approved plan of arrangement under the Business Corporations Act (British Columbia). The consummation of the transaction is subject to a number of conditions customary to transactions of this nature, including, among others, the adoption of a resolution approving the transaction at a special meeting of Gold Bull shareholders by: (i) at least 66-2/3rds per cent of votes cast by Gold Bull shareholders present in person or represented by proxy at the meeting; and (ii) a majority of the votes cast by Gold Bull shareholders present in person or represented by proxy at the meeting, excluding votes attached to any particular shareholder as required under Multilateral Instrument 61-101, Protection of Minority Security Holders in Special Transactions.

MI 61-101 provides that, in certain circumstances, where a related party (as defined in MI 61-101) of an issuer is entitled to receive a collateral benefit (as defined in MI 61-101) in connection with an arrangement transaction such as the transaction, such transaction may be considered a business combination for the purposes of MI 61-101 and subject to minority shareholder approval requirements. However, there are certain exceptions to these requirements. An independent committee of Gold Bull's board will conduct a collateral benefit assessment and applicable disclosure and any vote exclusions will be disclosed in the information circular for the meeting.

Gold Bull expects to hold the meeting in late January or early February, 2025, and the transaction is expected to close shortly thereafter, subject to court approvals and other customary closing conditions. In addition to shareholder and court approvals, the transaction is also subject to, among other things, obtaining customary regulatory approvals, including applicable court and stock exchange approvals.

Further details regarding the terms and conditions of the transaction are set out in the agreement, which will be publicly filed by Gold Bull and Borealis under their respective SEDAR+ profiles. Additional information regarding the terms of the agreement and the background of the transaction will be provided in the information circular for the meeting, which will also be filed on Gold Bull's SEDAR+ profile.

Sandman project overview

The recent 2023 PEA considered a conventional heap leach mining operation targeting 38,000 ounces of gold produced per annum over a nine-year operation. Given the nature of the Sandman deposits (outcropping), a 2.2-million-tonne-per-annum production rate and very low strip ratio of 2.2:1 extract an average gold grade of 0.73 gram per tonne (g/t) gold (Au) (majority oxide). The economics for this scenario are very robust, with an 81-per-cent IRR (posttax) and an NPV (posttax and discount rate of 6 per cent) of $121-million (U.S.), with only a 1.3-year payback period (posttax).

The capital required to build the proposed mining operation is very modest at an initial preproduction capital of $31.5-million (U.S.) and phase 2 capital of $19.7-million (U.S.), paid by phase 1 mining revenues. Total LOM (life-of-mine) capital is $51.3-million (U.S.), for an all-in sustaining cost of $1,337 (U.S.) per ounce of gold (posttax).

Sandman's economics are highly sensitive to the gold price. The 2023 PEA used a gold price of $1,800 (U.S.). As determined in the sensitivity study completed as part of the PEA, at a gold price of $2,600 (U.S.), the NPV jumps dramatically from $121-million (U.S.) to $323.1-million (U.S.), with an IRR of 171.9 per cent, all on a posttax basis.

In December, 2020, Gold Bull purchased the Sandman project from Newmont. Gold mineralization was first discovered at Sandman in 1987 by Kennecott and the project has been intermittently explored since then. There are four known pit-constrained gold resources located within the Sandman project, consisting of 21.8 million tonnes at 0.7 g/t gold for 494,000 ounces of gold, comprising an indicated resource of 18.55 million tonnes at 0.73 g/t gold for 433,000 ounces of gold, plus an inferred resource of 3,246,000 tonnes at 0.58 g/t gold for 61,000 ounces of gold. Several of the resources remain open in multiple directions and the bulk of the historical drilling has been conducted to a depth of less than 100 metres. Sandman is conveniently located circa 30 kilometres northwest of the mining town of Winnemucca in Nevada. Over its history, more than $30-million (U.S.) has been spent on the project and there is a comprehensive plan of operations for exploration in place, allowing for immediate exploration across the entire project.
