Agnico Eagle and Kirkland Lake Gold Announce Merger of Equals to Create Highest-Quality Senior Gold Producer

(All amounts expressed in U.S. dollars unless otherwise noted)

TORONTO, Sept. 28, 2021 /PRNewswire/ - Agnico Eagle Mines Limited (TSX: AEM) (NYSE: AEM) ("Agnico Eagle" or the "Company") and Kirkland Lake Gold Ltd. (TSX: KL) (NYSE: KL) (ASX: KLA) ("Kirkland Lake Gold") announced today that they have entered into an agreement (the "Merger Agreement") to combine in a merger of equals (the "Merger"), with the combined company to continue under the name "Agnico Eagle Mines Limited". The Merger will establish the new Agnico Eagle as the gold industry's highest-quality senior producer, with the lowest unit costs, highest margins, most favourable risk profile and industry-leading best practices in key areas of environmental, social and governance ("ESG"). Upon closing of the Merger, the Company is expected to have $2.3 billion of available liquidity, a mineral reserve base of 48 million ounces of gold, (969 million tonnes at 1.53 grams per tonne), which has doubled over the last 10 years, and an extensive pipeline of development and exploration projects to drive sustainable, low-risk growth.

The Merger will create a best-in-class gold mining company operating in one of the world's leading gold regions, the Abitibi-Greenstone Belt of northeastern Ontario and northwestern Quebec (the "Abitibi"), with superior financial and operating metrics. Consolidation within the Abitibi will also provide the new Agnico Eagle with significant value creation opportunities through synergies and other business improvement initiatives.  Additionally, the Company is established uniquely as the only gold producer in Nunavut and well positioned internationally with profitable and prospective assets in Australia, Finland, and Mexico.

The combination of Agnico Eagle and Kirkland Lake Gold combines each company's strengths by bringing together two industry leaders in growing per share value in key metrics such as production, mineral reserves, cash flow and net asset value. Both companies also share a strong commitment to returning capital to shareholders, with a total of $1.6 billion being returned through dividend payments and share repurchases since the beginning of 2020 (on a pro forma basis).

Under the Merger Agreement, which the Board of Directors of both companies have unanimously approved, the new Agnico Eagle will be led by a combined board and management team of experienced mining and business leaders, bringing together the proven cultures, strengths and capabilities of both companies. The transaction is expected to close in December 2021 or in the first quarter of 2022.

Pursuant to the Merger Agreement, Kirkland Lake Gold shareholders will receive 0.7935 of an Agnico Eagle common share for each Kirkland Lake Gold common share held (the "Consideration"). The Consideration to Kirkland Lake Gold represents approximately a 1% premium to the 10-day volume weighted average prices on the Toronto Stock Exchange, as at close of trading Friday September 24, 2021 and implies a combined market capitalization of approximately $24 billion.  Upon closing, existing Agnico Eagle and Kirkland Lake Gold shareholders will own approximately 54% and 46% of the combined company, respectively.

Sean Boyd, Agnico Eagle's Chief Executive Officer stated, "This merger starts a new chapter in Agnico Eagle's 64-year history and creates the leading low risk global gold company with growing production, low costs and strong ESG leadership.  The transaction creates a company with a strong platform of people, assets and financial resources to continue to build and operate a long term sustainable and self funding business.  Kirkland Lake is an excellent cultural fit with Agnico Eagle, and we look forward to working together to further grow our business through exploration, mine development and optimization of our high-quality asset base.  Over time, we believe that the gold industry will continue to evolve and consolidate and with this transaction we are well positioned take advantage of high-quality opportunities and be a true Canadian mining champion."

Tony Makuch, President and CEO of Kirkland Lake Gold, stated, "We are very pleased and excited to be entering into a combination with Agnico Eagle.  It is a unique 'strength-on-strength' transaction that combines the two global gold producers with the best track records for increasing per share value.  The deal creates an industry leader with a dominant position in the Canadian market that is deserving of a premium valuation and is poised to generate superior long-term shareholder value going forward.  The transaction represents a true merger of equals, with the business of both companies to benefit from the significant financial strength of the merged company, the extensive pipeline of development and exploration projects to drive future growth, and the potential to realize significant operational and strategic synergies along the Abitibi-Kirkland Lake corridor.  It is the right deal for our company and its shareholders, our people, the communities where we operate, and all of our key stakeholder groups."

Strategic Rationale for the Merger

Key strategic, financial and operational advantages of the combined business include:

• Creates the Highest Quality Senior Gold Producer – The Merger will create the industry's highest-quality and lowest-risk senior gold producer. With expected production of approximately 3.4 million ounces in 2021 at the lowest all-in sustaining costs per ounce amongst the senior gold producers, the Company remains focused in low-risk jurisdictions and regions with high geological potential.
• Maintains a Proven and Trusted Senior Leadership Team and Board with a Strong Track Record of Creating Value Per Share – The combined leadership team will maintain the consistent and proven strategy of growing both production and profitability per share.
• Extends Industry Leadership in ESG and Enhances the Capacity to Make Longer Term ESG Focused Investments – The combined entity will be a leader in energy performance and GHG emissions intensity, with a commitment to be Net Zero by 2050 or earlier.
• Enhances Position in one of the Most Prolific and Prospective Gold Regions in the World – The Merger solidifies the new Agnico Eagle as Canada's leading gold producer, with expected annual production in the country of approximately 2.5 million ounces in 2021 (on a pro forma basis).  The combined portfolio will be anchored by high-quality gold production in Ontario, Quebec and Nunavut in Canada, as well as at Fosterville in Victoria, Australia, Kittila in the Lapland region of Northern Finland and Pinos Altos and La India in Northern Mexico.
• Drives Fundamental Value Creation from Significant Unique Synergies Estimated at $0.8B over 5 Years and $2B over 10 Years (Pre-Tax) – The Merger provides a unique opportunity to unlock significant operational and strategic synergies along the Abitibi-Kirkland Lake corridor and to leverage sector-leading technical expertise to surface additional value across the portfolio.
• Highlights Track Record of Growing Mineral Reserves and Mineral Resources – The Merger combines the only two major gold companies to have grown mineral reserves and production per share over the last 10 years through consistent investment in exploration and value-added acquisitions, with total mineral reserves increasing by 127% from 2011 to 48 million ounces at December 31, 2020 (on a pro forma basis).
• Enhances and Adds Flexibility to an Attractive Minesite and Project Pipeline – The Merger combines a robust pipeline of growth projects and exploration opportunities. These projects are located in existing mining camps and will drive manageable, low-risk, high-return production growth over the next decade.
• Provides the Financial Strength to Increase Capital Distributions to Shareholders While Investing in Growth Projects – The Merger significantly enhances the financial flexibility to fund both the robust pipeline of growth projects and to build on a proven track record of growing sustainable capital returns to shareholders while maintaining a strong balance sheet. In combination, Agnico Eagle and Kirkland Lake Gold have collectively returned $1.6 billion to shareholders through dividends and share repurchases since the beginning of 2020 and expects to further increase returns to shareholders in the future.

Non-IFRS Measures

The information in this news release includes the following non-IFRS financial measures: all-in sustaining costs per ounce of gold sold ("AISC") and Adjusted EBITDA. These financial measures do not have any standardized meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other issuers, even as compared to other issuers who may also be applying the World Gold Council ("WGC") guidelines, which can be found at http://www.gold.org. Management of Agnico Eagle and Kirkland Lake Gold believe that the use of these non-IFRS measures will assist analysts, investors and other stakeholders of the companies in understanding the costs associated with producing gold, understanding the economics of gold mining, assessing the companies' operating performance, the combined company's ability to generate free cash flow from current operations and to generate free cash flow on an overall company basis, and for planning and forecasting of future periods. However, AISC does have limitations as an analytical tool as it may be influenced by the point in the life cycle of a specific mine and the level of additional exploration or expenditures a company has to make to fully develop its properties. Accordingly, these non-IFRS measures should not be considered in isolation, or as a substitute for, analysis of the companies; results as reported under IFRS. A reconciliation of certain the non-IFRS measures presented in this news release is contained in each of Agnico Eagle's and Kirkland Lake Gold's most recently filed annual MD&A, which are available under their respective profiles on SEDAR at www.sedar.com.

Notes to Investors Regarding the Use of Mineral Reserves for Agnico Eagle

The mineral reserve estimates contained in this news release have been prepared in accordance with the Canadian securities administrators' (the "CSA") National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). These standards are similar to those used by SEC Industry Guide No. 7, as interpreted by the SEC staff. However, the definitions in NI 43-101 differ in certain respects from those under SEC Industry Guide 7. Accordingly, mineral reserve information contained in this news release may not be comparable to similar information disclosed by United States companies.  Under the SEC's Industry Guide 7, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.

For United States reporting purposes, the SEC has adopted amendments to its disclosure rules (the "SEC Modernization Rules") to modernize the mining property disclosure requirements for issuers whose securities are registered with the SEC under the United States Securities Exchange Act of 1934, as amended (the "Exchange Act"), which became effective February 25, 2019. The SEC Modernization Rules more closely align the SEC's disclosure requirements and policies for mining properties with current industry and global regulatory practices and standards, including NI 43-101, and replace the historical property disclosure requirements for mining registrants that were included in SEC Industry Guide 7. Issuers must begin to comply with the SEC Modernization Rules in their first fiscal year beginning on or after January 1, 2021, though Canadian issuers that report in the United States using the Multijurisdictional Disclosure System ("MJDS") may still use NI 43-101 rather than the SEC Modernization Rules when using the SEC's MJDS registration statement and annual report forms.

As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources."  In addition, the SEC has amended definitions of "proven mineral reserves" and "probable mineral reserves" in the SEC Modernization Rules, with definitions that are substantially similar to those used in NI 43-101.

The mineral reserve and mineral resource data set out in this news release are estimates, and no assurance can be given that the anticipated tonnages and grades will be achieved or that the indicated level of recovery will be realized.  The Company does not include equivalent gold ounces for by-product metals contained in mineral reserves in its calculation of contained ounces and mineral reserves are not reported as a subset of mineral resources.

Scientific and Technical Information

The scientific and technical information relating to Agnico Eagle's portion of the mineral reserves and mineral resources contained herein (other than the Canadian Malartic mine) has been approved by Dyane Duquette, P.Geo., Corporate Director, Reserves Development of the Company; relating to mineral reserves at the Canadian Malartic mine has been approved by Sylvie Lampron, Eng., Senior Project Mine Engineer at Canadian Malartic Corporation (for engineering) and Pascal Lehouiller, P.Geo., Senior Resource Geologist at Canadian Malartic Corporation (for geology), each of whom is a "Qualified Person" for the purposes of NI 43-101.

Assumptions used for the December 31, 2020 mineral reserves estimate at all mines and advanced projects reported by Agnico Eagle

NI 43-101 requires mining companies to disclose mineral reserves and mineral resources using the subcategories of "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources".  Mineral resources that are not mineral reserves do not have demonstrated economic viability.

A mineral reserve is the economically mineable part of a measured and/or indicated mineral resource.  It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at pre-feasibility or feasibility level as appropriate that include application of modifying factors.  Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified.  The mineral reserves presented in this news release are separate from and not a portion of the mineral resources.

Modifying factors are considerations used to convert mineral resources to mineral reserves.  These include, but are not restricted to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors.

A proven mineral reserve is the economically mineable part of a measured mineral resource.  A proven mineral reserve implies a high degree of confidence in the modifying factors.  A probable mineral reserve is the economically mineable part of an indicated and, in some circumstances, a measured mineral resource.  The confidence in the modifying factors applying to a probable mineral reserve is lower than that applying to a proven mineral reserve.
