ESSA Pharma Announces New Listing on the TSX Venture Exchange Concurrent with Voluntary Delisting from the TSX

TSX VENTURE LISTING EXPECTED TO IMPROVE OPERATING EFFICIENCY, LOWER COSTS AND PROVIDE ENHANCED FINANCING FLEXIBILITY

COMPANY'S SHARES TO REMAIN LISTED ON NASDAQ CAPITAL MARKET

VANCOUVER and HOUSTON, Nov. 22, 2017 /PRNewswire/ - ESSA Pharma Inc. (TSX: EPI; NASDAQ: EPIX) ("ESSA" or the "Company"), a pre-clinical-stage pharmaceutical company focused on the development of novel small molecule drugs for the treatment of prostate cancer, today announced that the Company is listing its common shares on the TSX Venture Exchange (TSXV). ESSA expects that its common shares will begin trading under symbol "EPI" on the TSXV on or about November 27, 2017. Concurrently, the Company has applied for the voluntary delisting of its common shares, currently listed under symbol "EPI",  from the Toronto Stock Exchange TSX, which is currently anticipated to occur on or about November 25, 2017. ESSA's common shares will continue to be listed on the NASDAQ Capital Market under symbol "EPIX".

"Following a thorough evaluation, ESSA's  board of directors determined that it was in the best interests of the Company and its shareholders to list the Company's common shares on the TSXV, while concurrently voluntarily delisting from the TSX," said Dr. David R. Parkinson, President and Chief Executive Officer of ESSA. "We believe that a listing on the TSXV will allow for improved operating efficiency, lower costs and enhanced financing flexibility for the Company, while providing shareholders continued liquidity on a recognized stock exchange.

ESSA is not required to seek shareholder approval for the delisting of its common shares from the TSX, as an acceptable alternative market will exist for the common shares on or about the anticipated delisting date.

About ESSA Pharma Inc.
ESSA is a preclinical-stage pharmaceutical company focused on developing novel and proprietary therapies for the treatment of CRPC in patients whose disease is progressing despite treatment with current therapies. ESSA believes that its proprietary compounds can significantly expand the interval of time in which patients suffering from CRPC can benefit from hormone-based therapies, by disrupting the AR signaling pathway that drives prostate cancer growth and by preventing AR transcriptional activity by binding selectively to the NTD of the AR.  A functional NTD is essential for transactivation of the AR. In preclinical studies, blocking the NTD has demonstrated the capability to overcome the known AR-dependent mechanisms of CRPC.  ESSA was founded in 2009.
