Mako Mining to Acquire Goldsource Mines Creating a Scalable Diversified Gold Producer with a Platform for Growth

VANCOUVER, March 26, 2024 - Mako Mining Corp. ("Mako") (TSXV:MKO) (OTCQX:MAKOF) and Goldsource Mines Inc. ("Goldsource") (TSXV:GXS) (OTCQX:GXSFF) are pleased to announce that they have entered into an arrangement agreement (the "Arrangement Agreement"), pursuant to which Mako will acquire all of the issued and outstanding common shares of Goldsource (the "Goldsource Shares"), in exchange for common shares of Mako (the "Mako Shares"), by way of a plan of arrangement (the "Transaction").

The Transaction will create a company that will combine Mako's highly profitable Nicaraguan gold operations and mine-building team with Goldsource's 100% owned Eagle Mountain Gold Project ("Eagle Mountain") in Guyana, South America. The combined company will bring together an experienced management team, proven in the construction and operation of scalable mines with low capital intensity profiles, and who have discovered new precious metal deposits across multiple jurisdictions over the last two decades. The new Mako will have the cash flow, project pipeline, proven management team, and district-scale exploration potential that will enhance Mako's current growth trajectory while creating a platform for rapid growth. Further details of the Transaction are outlined below.


Transaction Highlights

• Geographic diversification and enhanced growth pipeline by combining Mako's high-grade and low-cost mining operations with Goldsource's low capital intensity Eagle Mountain project. Significant combined mineral endowment with district-scale exploration potential in both Nicaragua and Guyana


• Leveraging Mako's proven engineering and construction teams to accelerate the development of Eagle Mountain. The January 2024 Preliminary Economic Assessment ("PEA") for Eagle Mountain demonstrated potential for robust economics via a phased development plan with an after-tax internal rate of return ("IRR") of 57% and an after-tax net present value ("NPV") discounted at 5% of US$292 million at US$1,850 per ounce ("oz").[1] The shallow open pit plan with an anticipated 15-year mine life is well suited for Mako's operating team


• Mako's robust free cash flow generation and access to capital help accelerate and derisk the development of Eagle Mountain. Upon completion of the Transaction, it is anticipated that cash flow from Mako's San Albino mine ("San Albino") in Nicaragua and its access to capital will be utilized to accelerate the development at Eagle Mountain and to reach a production decision as soon as practicable


• Geological similarities between assets leverages recent mine building experience with near term development opportunities. Both San Albino and Eagle Mountain benefit from the advantageous geological structure of shallow dipping ore bodies, allowing for streamlined extraction processes and maximizing resource recovery. The plant flow sheet recommended for Eagle Mountain is nearly identical to the plant that Mako designed, engineered and successfully built themselves, which is expected to greatly reduce operational risk and potential for capex overruns


• Proven team and Board of Directors unlocking synergies & creating value - Post Transaction, the consolidated company will be led by a strengthened board and management team to be comprised of Eric Fier (Chairman), Akiba Leisman (CEO), Steve Parsons (President) and Jesse Munoz (COO), with a proven track record and in-country expertise, including exploration success, mine building, operations, community engagement and monetization


• Expanded capital markets presence & institutional shareholder base including key strategic investors - Concurrent with the execution of the Arrangement Agreement, funds managed by Wexford Capital LP (collectively, "Wexford"), Mako's largest shareholder, have provided Goldsource with a C$2 million bridge loan (the "Bridge Loan") to fund anticipated activities at Eagle Mountain through the completion of the Transaction

Akiba Leisman, Chief Executive Officer of Mako, commented: "This Transaction is a true "hand-in-glove" partnership. The scalability of Goldsource's Eagle Mountain is a direct analogue to that of Mako's San Albino mine. Both properties have district scale potential, with the ability to unlock that potential through cash flow. The teams have worked together as colleagues going back nearly two decades, which is expected to make integration of the two companies seamless. Lastly, this Transaction is the establishment of a platform for growth. The combined attributes of both companies are significantly better than what each individually brings to the table, and we expect to utilize this platform to grow Mako accretively and significantly."

Goldsource Executive Chairman, Eric Fier, CPG, P.Eng, stated, "Mako's successful approach to the development of the San Albino mine is something we watched closely during the 2020-2022 period, due in part because it is analogous to our plans for the development of Eagle Mountain, but also because we know Jesse Munoz and his construction team from prior projects that we've been involved with. This team has a solid track record and many decades of experience building mines, which is a unique offering for a junior gold producer and one that we believe is a great fit for our phased development plans at Eagle Mountain."

Goldsource Chief Executive Officer, Steve Parsons, P.Eng, stated, "The business combination with Mako offers Goldsource shareholders direct exposure to gold production and cash flow from the San Albino mine. The significant broadening of technical bandwidth, including Mako's mine development and construction expertise, is expected to expedite the timeline for establishing the Eagle Mountain Project as a near-term, low capital intensity development opportunity. Additionally, the business combination affords Goldsource shareholders exposure to Mako's aggressive exploration program at the high-grade San Albino mine and to the district-scale exploration potential which covers 28 km of prospective strike."


Benefits to Goldsource Shareholders:

• Meaningful upfront premium of approximately 40.9% based on spot and approximately 52.1% based on Mako's and Goldsource's 20-day volume-weighted average price on the TSX Venture Exchange (the "TSXV") as at March 25, 2024


• Clear path to over 100,000 ounces per year of gold production with a demonstrated record of fiscal discipline and history of shareholder value creation


• Access to a strong balance sheet and robust cash flow generation to rapidly advance Eagle Mountain while funding exploration initiatives


• Exposure to the San Albino-Murra gold district with over 28 km of strike length, with orogenic style gold mineralization across hundreds of targets identified within the ~188 km² land package


• Backing by key strategic investors, notably Wexford, which will be providing the Bridge Loan to fund near-term anticipated activities at Eagle Mountain


• With the consolidation of management and resources, Goldsource's shareholders gain exposure to an accelerated timeline to Eagle Mountain development by securing access to a well-capitalized gold producer with mine building expertise

Benefits to Mako Shareholders:

• Addition of a high-quality gold asset in Guyana, a mining friendly country undergoing rapid growth and development, which is expected to enhance Mako's operating platform


• Exposure to robust project economics from the January 2024 PEA outlining an after-tax IRR of 57% and an after-tax NPV discounted at 5% of US$292M[2]


• Jurisdiction diversification reducing risk concentration associated with individual projects or regions


• Exposure to an expected 15-year mine life, with a phased development plan and resources of 1,183,000 ounces of gold grading 1.18 g/t in indicated mineral resources, and an additional 582,000 ounces of gold grading 0.98 g/t in inferred mineral resources[3].


• Accretive on key operating and financial per share metrics
