Imbo East – Greenfields Exploration in Close Proximity to Adumbi Deposit

The focus of greenfields exploration at Imbo during 2020/21 has been along trend to the southeast across the Imbo river at Imbo East (84.68% owned by Loncor Gold).

The area is along trend and approximately 8-10 kilometres to the southeast from the expanding 3.466-million-ounce Adumbi, Kitenge and Manzako deposits previously delineated in the northwest of the 122 square kilometre project area.

In early 2021 analytical results were received for all soil samples from the completed 5.4 kilometre by 2.3 kilometre grid, east of the Imbo River where soil samples were collected every 40 metres on lines 160 metres apart. Geological mapping, soil geochemical, rock chips and channel sampling of old colonial trenches and artisanal workings outlined four significant mineralized trends - Esio Wapi, Museveni, Mungo Iko and Paradis (see Figures 1 and 2).

At Esio Wapi, soil geochemical results have outlined a number of plus 130 ppb Au (parts per billion) gold in soil anomalies with a maximum value of 2,230 ppb Au over a 1.9 kilometre long mineralized trend (see Figure 2). As announced previously (see Loncor’s press release dated September 21 2020), channel sample results from old colonial workings included 19.80 metres grading 1.58 g/t Au (open to the northeast), 8 metres grading 1.11 g/t Au and 5.0 metres grading 1.65 g/t Au in brecciated banded ironstone (BIF) and metasediment. Individual rock sample values included 15.10 g/t and 7.88 g/t Au in quartz veins, 6.39 g/t and 3.08 g/t Au in BIF and 9.06 g/t, 7.91 g/t and 3.24 g/t Au in metasediments.

On the Paradis trend, soil sample results have outlined a broad 1.0 kilometre trend (plus 130 ppb Au) with maximum value of 870 ppb Au. Significant channel samples along the Paradis trend include 6.8 metres grading 5.44 g/t Au (open to the southwest) in metasediments with quartz veins. Individual rock sample values included 22.40 g/t, 5.84 g/t and 2.31 g/t Au in quartz veins.

On the Museveni mineralized trend, anomalous soil samples and artisanal workings occur over a strike of 3.2 kilometres with a maximum value of 5,850 ppb Au in soils. Channel samples from the artisanal workings include 6.0 metres grading 4.37 g/t Au and 1.40 metres grading 62.10 g/t Au and represent high grade quartz veins in metasediment. Individual rock sample values included 53.90 g/t, 32.80 g/t and 32.60 g/t Au in quartz veins and 18.10 g/t Au in metasediment.

On the Mungo Iko trend, soil samples have outlined a 3.1 kilometre long mineralized trend (plus 130ppb Au) with maximum value of 1,540 ppb Au. Individual rock sample values include 12.30 g/t and 3.50 g/t Au in brecciated BIF, 14.20 g/t, 4.81 g/t, and 3.68 g/t Au in metasediments, and 1.97 g/t Au in quartz veins. Further mapping is required to determine whether the eastern part of the Mungo Iko trend represents a faulted extension of the Esio Wapi trend.

Additional infill soil sampling, augering and channel sampling will be undertaken at Esio Wapi, Paradis and Museveni to better define these mineralized trends prior to outlining drill targets later in the year.
