Press Release

Loncor to resume drilling on its 3.66 Million Ounce Adumbi Deposit and Four
Prospects on its Imbo Exploitation Licence

• Two rigs to target gold mineralisation below the open pit and an additional rig will undertake scout drilling of four exploration targets along the Adumbi mineralised structural trend

Toronto, Canada – August 13, 2024 – Loncor Gold Inc. ("Loncor" or the "Company") (TSX: "LN"; OTCQX: "LONCF”; FSE: "LO5") is pleased to announce that drilling equipment and personnel have arrived at the Adumbi camp to resume drilling on the Company’s flagship Adumbi gold project and at four prospects within the Imbo exploitation licence and where Loncor Gold has a 84.68% attributable interest.

Adumbi is situated approximately 220 kilometres from Africa’s largest gold mine, Barrick Gold/ AngloGold Ashanti’s Kibali Gold Mine, a hub for many mining related contractors in the DRC.

Two core rigs will focus on a 11,000-metre-deep drilling program below the Adumbi open pit where an indicated mineral resource of 1.88 million ounces of gold (28.185 million tonnes grading 2.08 g/t Au), and an inferred mineral resource of 1.78 million ounces of gold (20.83 million tonnes grading 2.65 g/t Au) have already been delineated within a USD1,600/oz open pit shell. 

The Adumbi resource remains open at depth below the USD1,600/oz pit shell with the favourable Banded

Ironstone Formation (BIF) host increasing in thickness.  As stated in the Company’s press release of December 19, 2023, the Company estimates the potential Adumbi underground exploration target below the USD1,600/oz pit shell as between 8.9 million tonnes to 9.6 million tonnes grading 4.7 g/t Au to 4.9 g/t Au to a depth of 800 metres (reference is made to the said press release, which can be found at SEDAR+ at www.sedarplus.ca, for additional information with respect to this estimate).  These potential quantities and grade are conceptual in nature as there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the Adumbi underground exploration target being delineated as a mineral resource.

Fifteen intersections are proposed below the pit shell in order to outline an inferred underground mineral resource (see Figure 1 below showing intended 15 drill interceptions below the Adumbi pit shell).  Of the fifteen proposed intersections, six interceptions will be wedged off nine deeper holes in order to save time and costs. 

In addition, a further core rig has been mobilised to undertake initial scout drilling on four exploration targets, 8 to 13 kilometres to the southeast from Adumbi on the same major structural shear across the Imbo river at Imbo East.  Geological mapping, soil geochemical, rock chips and channel sampling of old colonial trenches and artisanal workings have outlined four significant mineralized trends at Esio Wapi, Museveni, Mungo Iko and Paradis.  An initial 12 hole (2,400 metre) drill program will test these four targets.

Loncor’s Chief Executive Officer, John Barker, commented: “The imminent drilling below Adumbi’s 3.66 million ounce “in pit” resource has the potential to push the high-grade deposit aggressively towards Tier 1 status.  The drilling has been made possible by the cash raised by the Cdn$13.5 million asset sale announced in December 2023, without recourse to equity holders.” 

Loncor’s independent geological consultants Minecon Resources and Services Limited undertook the Adumbi underground exploration target tonnage and grade estimation ranges.  The Adumbi 3-dimensional

(“3-D”) model was constructed using cross sectional and horizontal flysch plans of the geology and mineralization and was used to assist in constraining the 3-D geological model.  This underground exploration target has been estimated to a maximum depth of 800 metres below surface.

Technical Report

Additional information with respect to the Company’s Adumbi deposit (and other properties of the Company within its Imbo Project) is contained in the technical report of New SENET (Pty) Ltd and Minecon Resources and Services Limited dated December 15, 2021 and entitled "NI 43-101 Preliminary Economic Assessment of the Adumbi Deposit in the Democratic Republic of the Congo".  A copy of the said report can be obtained from SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov.   

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 holds an indicated mineral resource of 1.88 million ounces of gold (28.185 million tonnes grading 2.08 g/t gold), and the

Adumbi deposit and two neighbouring deposits hold an inferred mineral resource of 2.090 million ounces of gold (22.508 million tonnes grading 2.89 g/t Au), with 84.68% of these resources being attributable to Loncor.  Following a drilling program carried out by the Company at the Adumbi deposit in 2020 and

2021, the Company completed a Preliminary Economic Assessment (“PEA”) of the Adumbi deposit and announced the results of the PEA in December 2021.  The Makapela Project (which 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).  On December 13, 2023, Loncor announced the sale of the Makapela Project, which sale is expected to be completed during the third quarter of 2024.
