Loncor Resources Inc. (" Loncor " or the " Company ") (TSX: "LN"; OTCQX: "LONCF"; FSE: "LO51") is pleased to announce further significant assay results from its drilling program within its 84.68%-owned Imbo Project in the eastern part of the Ngayu greenstone belt in the Democratic Republic of the Congo. The deepest borehole drilled to date at its flagship Adumbi deposit, LADD009 intersected 32.15 metres grading 6.17 grammes per tonne (gt) gold (including 1.46 metres grading 94.77 gt Au), 15.36 metres grading 3.73 gt gold (including 5.89 metres grading 6.56 gt Au), 5.00 metres grading 3.17 gt gold and 7.45 metres grading 1.48 gt gold.
Mineralized sections for borehole LADD009 are summarised in the table below:
| Borehole Number | From (m) | To (m) | Intersected Width (m) | Grade (g/t) Au |
| LADD009 | 559.76 | 564.76 | 5.00 | 3.17 |
| LADD009 | 581.90 | 614.05 | 32.15 | 6.17 |
| LADD009 including | 599.05 | 600.51 | 1.46 | 94.77 |
| LADD009 | 629.56 | 644.92 | 15.36 | 3.73 |
| LADD009 including | 632.00 | 637.89 | 5.89 | 6.56 |
| LADD009 | 650.50 | 657.95 | 7.45 | 1.48 |
Borehole LADD009 had an inclination of minus 75 degrees and azimuth of 218 degrees at the start of hole and regular measurements of inclination and azimuth were taken at 30 metre intervals down the hole. All core was orientated, and it is estimated that the true widths of the mineralised sections are approximately 82% of the intersected width. All intercepted grades are uncut with maximum internal dilution equal to or less than 4 metres of intersected width. Borehole LADD009 intersected the mineralization at a depth of approximately 140 metres below the open pit shell (see Figures 2 and 3 below). Boreholes LADD012 and LADD013 are currently being drilled (LADD011 was abandoned before reaching target depth due to mechanical problems and LADD013 is being drilled in its place).
Commenting on these latest drilling results, Loncor President Peter Cowley said: "Borehole LADD009 is the deepest hole drilled to date at Adumbi as well as the highest value in terms of the product of grade multiplied by true width for the multiple intersections (see Figure 2). These excellent results combined with previous results from the ongoing drilling program indicate that gold grades are increasing with depth. We continue to be excited by the results at Adumbi. The holes from our current drilling program have intersected significant widths and grades and will increase the current open pittable, inferred mineral resource of 2.19 million ounces (28.97 million tonnes grading 2.35 g/t gold) at the Adumbi deposit. Studies are underway to quantify this increase."
The gold mineralization at Adumbi is associated with a thick package (up to 130 metres) of interbedded banded ironstone and quartz carbonate and chlorite schist with higher grade sections being found in a strongly altered siliceous unit termed "Replaced Rock" (RP) where structural deformation and alteration has completely destroyed the primary host lithological fabric. Disseminated sulphide assemblages include pyrite, pyrrhotite and arsenopyrite which can attain up to 20% of the total rock in places.
The objective of the current drilling program at Adumbi is to outline additional mineral resources to the current inferred mineral resource of 2.5 million ounces of gold on Loncor's 84.68%-owned Imbo Project which contains the Adumbi, Kitenge and Manzako deposits (inferred mineral resources of 30.65 million tonnes grading 2.54 g/t Au).
Quality Control and Quality Assurance
Drill cores for assaying were taken at a maximum of one-metre intervals and were cut with a diamond saw, with one-half of the core placed in sealed bags by Company geologists and sent to the Company's on-site sample preparation facility. The core samples were then crushed down to 80% passing minus 2 mm and split with one half of the sample up to 1.5 kg pulverized down to 90% passing 75 microns. Approximately 150 grams of the pulverized sample was then sent to the SGS Laboratory in Mwanza, Tanzania (independent of the Company). Gold analyses were carried out on 50g aliquots by fire assay. In addition, check assays were also carried out by the screen fire assay method to verify high-grade sample assays obtained initially by fire assay. As part of the Company's QA/QC procedures, internationally recognized standards, blanks and duplicates were inserted into the sample batches prior to submitting to SGS Laboratory.

About Loncor Resources Inc.
Loncor is a Canadian gold exploration company focussed on the Ngayu Greenstone Gold Belt in the northeast of the Democratic Republic of the Congo (the " DRC "). The Loncor team has over two decades of experience of operating in the DRC. Loncor's growing resource base in the Ngayu Belt currently comprises the Imbo and Makapela Projects. At the Imbo Project, the Adumbi deposit and two neighbouring deposits hold an inferred mineral resource of 2.5 million ounces of gold (30.65 million tonnes grading 2.54 g/t Au), with 84.68% of this resource being attributable to Loncor. Loncor is currently carrying out a drilling program at the Adumbi deposit with the objective of outlining additional mineral resources. The Makapela Project (which is 100%-owned by Loncor and is located approximately 50 kilometres from the Imbo Project) has an indicated mineral resource of 614,200 ounces of gold (2.20 million tonnes grading 8.66 g/t Au) and an inferred mineral resource of 549,600 ounces of gold (3.22 million tonnes grading 5.30 g/t Au).
Loncor also has several joint ventures with Barrick (TSX: "ABX"; NYSE: "GOLD") in the Ngayu Belt. The joint venture areas are located approximately 220 kilometres southwest of the large Kibali gold mine, which is operated by Barrick. As per the joint venture agreements entered into between Loncor and Barrick, Barrick manages and funds exploration on approximately 2,000 km 2 of Loncor ground in the Ngayu Belt until the completion of a pre-feasibility study on any gold discovery meeting the investment criteria of Barrick. Subject to the DRC's free carried interest requirements, Barrick would earn 65% of any discovery with Loncor holding the balance of 35%. Loncor will be required, from that point forward, to fund its pro-rata share in respect of the discovery in order to maintain its 35% interest or be diluted. Loncor's Imbo and Makapela Projects do not form part of the joint ventures with Barrick.
