Information from the link below which gives credence to Management Confidence that Adumbi Resources will have close to 5 m ounces ( 3.5 currently ) at its next update in late 2021 and that a significant underground resource will also have been defined.
One hole yet to report from initial 2021 drilling program and about 12 more holes from the new drilling program to begin shortly, if not already,,,

On April 27 2021, Loncor announced a 44% increase in mineral resources at its Adumbi deposit in the Imbo Project (Loncor 84.68%).
Compared to the inferred mineral resource of 2.19 million ounces of gold (28.97 million tonnes grading 2.35 g/t Au) outlined in April 2020 the inclusion of six holes from the 7000 metre 2020/21 program increased the Adumbi inferred mineral resource to 3.153 million ounces of gold (41.32 million tonnes grading 2.37 g/t Au), constrained within a US$1,500 open pit shell.
Drilling continues to assess the underground potential at Adumbi. Loncor believes that during 2021 Adumbi could delineate a significant underground resource.
Recent drilling has suggested that the ore body at Adumbi may have a shallower plunge than previously predicted, a potential positive for resource ounce generation if it proves to be the case.
Southeast of Adumbi there is ongoing exploration at Imbo East including gridding, soil sampling, trenching and channel sampling in order to generate potential drill targets (further detail can be seen within the Imbo East section of the website).
The addition of exploration targets in relative close proximity to Adumbi creates the potential of a larger mining district, with all the upside that such a development would offer.
In addition, two undrilled targets have been outlined close to the Adumbi deposit.
Both these target areas were identified from the compilation and interpretation of previous, historical exploration data including soil geochemistry, rock chip and channel sampling.
At Mambo Bado, 1.5 kilometres northwest of the Adumbi deposit, a prominent geochemical gold in soil anomaly is located on an extensional, E-W structural jog along the 14-kilometre northwest trending mineralized shear.
Two kilometres south of the Adumbi deposit, at Lisala, altered and brecciated BIF with anomalous rock sampling requires further follow up with gridding, soil sampling and additional channel sampling.
