Toronto, Canada -- June 5, 2018 -- Loncor Resources Inc. ("Loncor" or the "Company") (TSX: "LN") announces that it has applied to the Toronto Stock Exchange ("TSX") to extend the term of a total of 875,000 common share purchase warrants of the Company (the "Warrants"). These Warrants were issued as part of a private placement of securities of the Company which closed on June 29, 2016. Each of these Warrants (a) entitles the holder to purchase one common share of the Company at a price of Cdn$0.18, and (b) currently has an expiry date of June 29, 2018. The Company has applied to the TSX to extend such expiry date by one year to June 29, 2019. No insiders of the Company hold any of these Warrants, directly or indirectly. Finalization of this amendment to the Warrants is subject to the approval of the TSX. If such approval is obtained, this amendment will be effective ten business days from the date of this press release.

Loncor has been working with one of Africa's most successful gold mining companies, Randgold Resources (Nasdaq: GOLD), in its Ngayu Joint Venture whereby Randgold earns 65% to manage and sole fund an exploration program including delivery of a pre-feasibility study on any gold discovery that would meet Randgold's investment criteria (reference is made to Loncor's May 18, 2017 press release).
