Loncor Reports Wide Gold Intercepts of 34.63 m Grading 3.12 g/t Gold and 29.82 m Grading 1.77 g/t Gold at its Infill Drill Program at Adumbi

Significant mineralized sections for borehole LADD023 are summarised in the table below:

Note: It is estimated that the true width of the mineralised sections for core hole LADD023 is 76% of the intersected widths in the above table. Regular measurements of inclination and azimuth were taken at 30 metre intervals down the hole and all the core was orientated. All intercepted grades are uncut with maximum internal dilution equal to or less than 4 metres of intersected width.

Commenting on these latest drilling results, Loncor President Peter Cowley said: "This infill core hole was situated within the central part of the open pit shell with the objective of converting a good part of the 3.15 million ounce inferred resource into a higher confidence category. Results received for this infill program demonstrate very good continuity of the mineralised, banded ironstone formation ("BIF") package. Drilling has now been completed within the pit shell as well as below the pit to outline potential underground resources at depth. The focus at Adumbi is now metallurgical, processing, mining and infrastructural and financial studies in order to complete the Preliminary Economic Assessment (P.E.A) in December of this year."

Quality Control and Quality Assurance re Adumbi Deposit Drill Results
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 Gold 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 3.466 million ounces of gold (42.996 million tonnes grading 2.51 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).

Cautionary Note Concerning Forward-Looking Information
This press release contains forward-looking information. All statements, other than statements of historical fact, that address activities, events or developments that the Company believes, expects or anticipates will or may occur in the future (including, without limitation, statements regarding drill results at the Adumbi deposit, mineral resource estimates, converting inferred mineral resources at Adumbi into a higher confidence category, potential underground mineral resources, completing the Adumbi Preliminary Economic Assessment, potential mineralization, potential gold discoveries, drill targets, exploration results, and future exploration and development) are forward-looking information. This forward-looking information reflects the current expectations or beliefs of the Company based on information currently available to the Company. Forward-looking information is subject to a number of risks and uncertainties that may cause the actual results of the Company to differ materially from those discussed in the forward-looking information, and even if such actual results are realized or substantially realized, there can be no assurance that they will have the expected consequences to, or effects on the Company. Factors that could cause actual results or events to differ materially from current expectations include, among other things, the possibility that future exploration (including drilling) or development results will not be consistent with the Company's expectations, the possibility that drilling programs will be delayed, activities of the Company may be adversely impacted by the continued spread of the widespread outbreak of respiratory illness caused by a novel strain of the coronavirus ("COVID-19"), including the ability of the Company to secure additional financing, risks related to the exploration stage of the Company's properties, uncertainties relating to the availability and costs of financing needed in the future, failure to establish estimated mineral resources (the Company's mineral resource figures are estimates and no assurances can be given that the indicated levels of gold will be produced), changes in world gold markets or equity markets, political developments in the DRC, gold recoveries being less than those indicated by the metallurgical testwork carried out to date (there can be no assurance that gold recoveries in small scale laboratory tests will be duplicated in large tests under on-site conditions or during production), fluctuations in currency exchange rates, inflation, changes to regulations affecting the Company's activities, delays in obtaining or failure to obtain required project approvals, the uncertainties involved in interpreting drilling results and other geological data and the other risks disclosed under the heading "Risk Factors" and elsewhere in the Company's annual report on Form 20-F dated March 31, 2021 filed on SEDAR at www.sedar.com and EDGAR at www.sec.gov. Forward-looking information speaks only as of the date on which it is provided and, except as may be required by applicable securities laws, the Company disclaims any intent or obligation to update any forward-looking information, whether as a result of new information, future events or results or otherwise.
