  • Results include 32.15 metres grading 6.17 g/t gold (including 1.46 metres grading 94.77 g/t gold) and 15.36 metres grading 3.73 g/t gold (including 5.89 metres grading 6.56 g/t gold)

Loncor Resources Inc. (“Loncor” or the “Company”) (TSX: “LN”; OTCQX: “LONCF”; FSE: “LO51”) is pleased to announce further significant assay results from its drilling program within its 84.68%-owned Imbo Project in the eastern part of the Ngayu greenstone belt in the Democratic Republic of the Congo. The deepest borehole drilled to date at its flagship Adumbi deposit, LADD009 intersected 32.15 metres grading 6.17 grammes per tonne (g/t) gold (including 1.46 metres grading 94.77 g/t Au), 15.36 metres grading 3.73 g/t gold (including 5.89 metres grading 6.56 g/t Au), 5.00 metres grading 3.17 g/t gold and 7.45 metres grading 1.48 g/t gold.

Mineralized sections for borehole LADD009 are summarised in the table below:

Borehole NumberFrom (m)To (m)Intersected
Width (m)
Grade (g/t) Au

Borehole LADD009 had an inclination of minus 75 degrees and azimuth of 218 degrees at the start of hole and regular measurements of inclination and azimuth were taken at 30 metre intervals down the hole. All core was orientated, and it is estimated that the true widths of the mineralised sections are approximately 82% of the intersected width. All intercepted grades are uncut with maximum internal dilution equal to or less than 4 metres of intersected width. Borehole LADD009 intersected the mineralization at a depth of approximately 140 metres below the open pit shell (see Figures 2 and 3 below). Boreholes LADD012 and LADD013 are currently being drilled (LADD011 was abandoned before reaching target depth due to mechanical problems and LADD013 is being drilled in its place).

Commenting on these latest drilling results, Loncor President Peter Cowley said: “Borehole LADD009 is the deepest hole drilled to date at Adumbi as well as the highest value in terms of the product of grade multiplied by true width for the multiple intersections (see Figure 2). These excellent results combined with previous results from the ongoing drilling program indicate that gold grades are increasing with depth. We continue to be excited by the results at Adumbi. The holes from our current drilling program have intersected significant widths and grades and will increase the current open pittable, inferred mineral resource of 2.19 million ounces (28.97 million tonnes grading 2.35 g/t gold) at the Adumbi deposit. Studies are underway to quantify this increase.”

The gold mineralization at Adumbi is associated with a thick package (up to 130 metres) of interbedded banded ironstone and quartz carbonate and chlorite schist with higher grade sections being found in a strongly altered siliceous unit termed “Replaced Rock” (RP) where structural deformation and alteration has completely destroyed the primary host lithological fabric. Disseminated sulphide assemblages include pyrite, pyrrhotite and arsenopyrite which can attain up to 20% of the total rock in places.

The objective of the current drilling program at Adumbi is to outline additional mineral resources to the current inferred mineral resource of 2.5 million ounces of gold on Loncor’s 84.68%-owned Imbo Project which contains the Adumbi, Kitenge and Manzako deposits (inferred mineral resources of 30.65 million tonnes grading 2.54 g/t Au).
