George Town & St Peter Port, June 28, 2017 - Endeavour Mining Corporation (TSX:EDV OTCQX: EDVMF) ("Endeavour") and Avnel Gold Mining Ltd. (TSX:AVK) ("Avnel") are pleased to announce that they have reached an agreement under which Endeavour will acquire Avnel in an all-share transaction for a total consideration of approximately US$ 122 million (CAD$ 159 million). The terms of the transaction have been unanimously approved by the Boards of Directors of both companies.

Avnel holds an 80% interest in the Kalana Gold project ("Kalana") in Mali and holds significant exploration permits in the surrounding area. Kalana is a fully permitted feasibility-stage project based on a 1.2Mtpa carbon-in-leach ("CIL") plant and a single open-pit constrained reserve of approximately 2.0Moz grading 2.8 g/t. According to the feasibility study, it has an 18-year mine life and an expected production of 101,000 ounces per year at an average All-in Sustaining Cost ("AISC") of $784/oz (with 148,000 ounces on average during the first 5 years at an average AISC of $589/oz). The initial capital cost is forecast at $196.3 million and Kalana demonstrates robust economics with an after-tax NPV_5% of $257 million, an after-tax IRR of 38% and a payback of 1.2 years based on a gold price of $1,200/oz^[1].

Avnel has pursued optimization scenarios that, if adopted, could provide Kalana with an after-tax NPV_5% of US$321 million and an after-tax IRR of 50%. In addition, such optimization scenarios could reduce average AISC to US$730/oz over the 18-year mine life and to US$561/oz over the first five years. Endeavour expects to take advantage of its construction expertise, operating synergies and exploration experience to re-design and optimize the current feasibility study, which is expected to increase the annual production profile and improve the project economics.

Sébastien de Montessus, President & CEO, said: "We are delighted to have reached this agreement with Avnel. We believe that Kalana fits well within our strategy of building a high quality portfolio of long-life, low AISC assets with exploration upside. Furthermore, this acquisition expands our footprint in Mali and reinforces our project pipeline, which will allow us to continue to leverage our in-house construction expertise.

Kalana adds a third high-quality project to our portfolio, which we intend to develop following the completion of our Hounde and Ity CIL projects. In the interim, we look forward to optimizing the current feasibility study which should unlock further value for both Endeavour and Avnel shareholders, as well as benefiting our partners, the State of Mali and the local communities around Kalana."

Howard Miller, Chairman and CEO of Avnel, said: "This transaction with Endeavour will deliver many benefits to all our stakeholders. Avnel's shareholders will receive an immediate premium and benefit from the Kalana project being part of a diversified West African gold producer with significant growth potential and an experienced operational team. With a strong track record of successfully building mines on time and on budget in West Africa, we are confident that Endeavour is the ideal partner to develop Kalana. As such, this transaction will benefit our shareholders, the local community and our partners in the Malian government."


A compelling Transaction for all shareholders

Benefits For Endeavour Shareholders

ABOUT ENDEAVOUR

Endeavour Mining is a TSX-listed intermediate gold producer, focused on developing a portfolio of high quality mines in the prolific West-African region, where it has established a solid operational and construction track record.

Endeavour is ideally positioned as the major pure West-African multi-operation gold mining company, operating 5 mines across Côte d'Ivoire (Agbaou and Ity), Burkina Faso (Karma), Mali (Tabakoto), and Ghana (Nzema). In 2017, it expects to produce between 600koz and 640koz at an AISC of US$860 to US$905/oz. Endeavour is currently building its Houndé project in Burkina Faso, which is expected to commence production in Q4-2017 and to become its flagship low-cost mine with an average annual production of 190koz at an AISC of US$709/oz over an initial 10-year mine life, based on reserves. The development of the Houndé and Ity CIL projects are expected to lift Endeavour's group production to +900kozpa and decrease its average AISC to circa $800/oz by 2019, while exploration aims to extend all mine lives to +10 years.

ABOUT AVNEL

Avnel Gold is a TSX-listed gold mining, exploration and development company with operations in southwestern Mali in West Africa. The Company's focus is to develop its 80%-owned Kalana Main Project from a small underground mine into a low-cost, high-grade, open pit mining operation. The Company is also advancing exploration on several nearby satellite deposits on the 387 km² 30-year Kalana Exploitation Permit.

On January 9, 2017, the Company reported the results of an Optimized Feasibility Study ("OFS") prepared by Snowden Mining Industry Consultants. The OFS outlines an 18-year open-pit mine life at the Kalana Main Project recovering 1.82 million ozs of gold at an average "all-in sustaining cost" of $561/oz over the first five years of steady state production and $730/oz over the life of mine with an initial capital cost of $171 million. Utilising a gold price of $1,200/oz and a 5% discount rate, the OFS reported a net present value ("NPV") of $321 million after-tax and imputed interest, and an internal rate of return ("IRR") of 50% on a 100% project basis.

FORWARD-LOOKING INFORMATION

This news release includes certain "forward-looking statements". Forward-looking statement include, but are not limited to, Endeavour's expectations regarding its ability to increase annual production profile and improve project economics of Kalana and the receipt of the required shareholder approval and court sanction of the Scheme. All statements, other than statements of historical fact, included in this release, including the future plans and objectives of Endeavour and Avnel, are forward-looking statements that involve various risks and uncertainties.

There can be no assurance that forward-looking statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from Endeavour's or Avnel's expectations include, among others, risks related to international operations, the actual results of current exploration activities, conclusions of economic evaluations and changes in project parameters as plans continue to be refined as well as future prices of gold and silver, as well as those factors discussed in the section entitled "Risk Factors" in Endeavour's and Avnel's most recently completed Annual Information Forms, which are available on SEDAR (www.sedar.com). Although Endeavour and Avnel have attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.


NON-IFRS FINANCIAL MEASURES

Avnel's audited consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board and the accounting policies adopted by Avnel in accordance with IFRS.

Management uses both IFRS and non-IFRS measures to monitor and assess the operating performance of Avnel's operations. In this press release, certain non-IFRS performance measures are used to provide additional information, as Avnel believes that certain investors use these measures to assess the performance and prospectus of gold mining companies. These non-IFRS performance measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Non-IFRS performance measures do not have standardized definition under IFRS and therefore may not be comparable to similar measures presented by other organizations:

- "All-in Sustaining Cost" or "AISC" is defined in the feasibility study as mine site cash operating costs, which include costs such as mining, processing, administration, plus transport and refining of metals, stamp duty, and royalties, mine management fees to be earned by Avnel, plus sustaining capital costs, which includes community and environmental. These costs are then divided by the number of ounces of expected production to be sold to arrive at "On-site All-in Sustaining Cost per Ounce Sold".
