LEADING INDEPENDENT ADVISORY FIRMS ISS AND GLASS LEWIS SUPPORT PLAN OF ARRANGEMENT BETWEEN ENDEAVOUR MINING AND TRUE GOLD MINING

George Town, April 11, 2016 - Endeavour Mining Corporation ("Endeavour") (TSX: EDV) (OTCQX: EDVMF) is pleased to announce that both Institutional Shareholder Services Inc. ("ISS") and Glass Lewis & Co. ("Glass Lewis"), two leading independent proxy advisory firms whose analyses and recommendations are relied upon by many major institutional investment firms, mutual funds and fiduciaries, have recommended that shareholders of Endeavour and shareholders of True Gold Mining, Inc. ("True Gold") (TSX-V: TGM) support the proposed plan of arrangement (the "Arrangement") between the two companies at their special meetings scheduled for April 21, 2016.

Endorsing the Arrangement, ISS noted that "the all-stock transaction makes strategic sense as it will create a stronger combined entity with better access to financial markets and result [in] potential operational and administrative synergies." Glass Lewis, in turn, indicated "that the proposed transaction is supported by a clear strategic vision and tangible benefit for Endeavour shareholders, who will gain exposure to the low-cost Karma gold mine."

In addition, both ISS and Glass Lewis have recommended to Endeavour shareholders that they vote for the approval of the issuance of shares to La Mancha Holding S.àr.l. ("La Mancha") and the increase in the authorized share capital. As noted by ISS, "the dilution of the share issuance appears to be reasonably limited," while the increase in the authorized share capital "is considered generally acceptable."

All Endeavour shareholders are encouraged to read the information circular with respect to the Arrangement, which was mailed to shareholders of record as of March 15th, 2016. It is also available on SEDAR at www.sedar.com and Endeavour's website (www.endeavourmining.com).

The Board of Directors of Endeavour has unanimously recommended that shareholders vote in favour of the resolutions outlined in the circular.

Registered Endeavour Shareholders are encouraged to vote by proxy, which must be received by Computershare by 10:00 a.m. (EST) on April 19, 2016.

If you have any questions or require assistance in voting, please contact our proxy solicitation agent,
