Loncor makes further inroads in DRC gold belt

TSX listed Loncor Gold has applied for an exploitation permit for the development of its early stage Makapela gold resource in the Ngayu Greenstone Gold Belt in the northeast of the Democratic Republic of the Congo (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 grams per tonne of gold [g/t Au). 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, Loncor completed a Preliminary Economic Assessment (PEA) of the Adumbi deposit and announced the results of the PEA in December 2021.

Growing potential of Makapela  

The Makapela Project is located about 50km from Loncor’s flagship 3.66-million-ounce Adumbi deposit which already has a mining permit.

According to Loncor, Makapela 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) at a 2.75 g/t Au cut-off.

According to Loncor CEO John Barker, Makapela represents a high-grade opportunity either as a potential feed source for a future gold operation at Adumbi, or as an independent stand-alone high-grade project.

“The deposit remains open at depth, along strike, plus has a number of parallel zones that require further investigation. Within close proximity, there are a number of other deposits such as Mokepa and Mongaliema that historically have been drilled and could hold the potential of future ore feed for Makapela”says Barker.  

“The award of a mining permit at Makapela would create a second avenue to release value held within our deposits, and the company will continue to analyse both practical and corporate solutions to maximise the value attributed to all of Loncor’s assets,” says Baker.

Drilling core at Makapela

The Makapela mineralisation is hosted by a sequence of steeply-dipping basaltic volcanics containing thin BIF (banded ironstone formation) units. A total of 83 core holes have been drilled at Makapela with several significant drill intersections including 7.19m grading 64 g/t Au, 4.28m at 32.6 g/t Au, 3.47m grading 24.9 g/t Au, 4.09m at 21.7 g/t Au and 4.35m grading 17.5 g/t Au.

There are two principal, subvertical mineralised units at Makapela. Reef 1 is a quartz vein emplaced into a shear zone which crosscuts the basalt sequence at an acute angle and has an average true width and grade of 2.15m at 11.15 g/t Au and has been drilled over a strike of 480m and to a maximum vertical depth of 480m. Reef 2, an assemblage of brecciated quartz within a sheared BIF unit over a strike of at least 3km.

The best Reef 2 mineralisation occurs over a strike of 480m, where it has an average true width and grade of 3.52m at 8.44 g/t Au. Good potential exists for locating additional blind gold mineralisation along well-defined structures over an aggregate strike of over 5km.
