Loncor Gold Reports Multiple Gold Intersections from Its Deepest Drill Hole at Adumbi

Rhea-AI Summary

Loncor Gold (TSX: LN) (OTCQX: LONCF) has announced significant drilling results from its Adumbi deposit, which currently holds 3.66 million ounces of gold resources. The deepest drill hole LADD029 revealed multiple gold intersections including:

- 22.31 metres grading 3.05 g/t gold (including 4.64 metres at 5.83 g/t)
- 14.50 metres grading 4.24 g/t gold (including 10.17 metres at 5.23 g/t)
- 15.57 metres grading 3.35 g/t gold

The deposit currently contains an indicated mineral resource of 1.88 million ounces (28.185 million tonnes at 2.08 g/t Au) and an inferred mineral resource of 1.78 million ounces (20.83 million tonnes at 2.65 g/t Au) within a USD1,600/oz open pit shell. LADD029 extends gold mineralization to 805 metres below Adumbi Hill and intersected the thickest banded ironstone formation package ever drilled at Adumbi.

Positive

• Thickest banded ironstone formation package ever drilled (148m true thickness)
• Gold mineralization extended to 805m below surface

Negative

• None.

• Results from hole LADD029 reported 22.31 metres grading 3.05 g/t gold (including 4.64 metres grading 5.83 g/t gold), 14.50 metres grading 4.24 g/t gold (including 10.17 metres grading 5.23 g/t gold) and 15.57 metres grading 3.35 g/t gold

Toronto, Ontario--(Newsfile Corp. - April 25, 2025) - Loncor Gold Inc. (TSX: LN) (OTCQX: LONCF) (FSE: LO5) ("Loncor" or the "Company") is pleased to announce very encouraging drilling results from its deep drilling program at the Company's 3.66 million ounce Adumbi deposit, 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. Borehole LADD029 which is the deepest borehole drilled at Adumbi intersected 22.31 metres grading 3.05 grammes per tonne (g/t) gold (including 4.64 metres grading 5.83 g/t gold), 14.50 metres grading 4.24 g/t gold (including 10.17 metres grading 5.23 g/t gold) and 15.57 metres grading 3.35 g/t gold (see the table and Figures below).

Significant mineralized sections for borehole LADD029 are summarised in the table below:

Borehole Number	From (m)	To (m)	Intersected Width (m)	Grade (g/t) Au
LADD029	672.04	678.95	6.91	1.34
LADD029	713.00	727.50	14.50	4.24
LADD029 Including	717.33	727.50	10.17	5.23
LADD029	750.26	772.57	22.31	3.05
LADD029 Including	750.26 766.50	753.56 771.14	3.30 4.64	6.07 5.83
LADD029	802.20	817.77	15.57	3.35

 

Note 1: It is estimated that the true width of the mineralised sections for core hole LADD029 is 64% of the intersected widths in the above table. Regular measurements of inclination and azimuth were taken at 30 metre intervals down the hole and all the core was orientated. All intercepted grades are uncut with maximum internal dilution equal to or less than 4 metres of intersected width.
Note 2: Assay results still to be received for banded ironstone formation (BIF) from 817.77 to 855 metres.

Commenting on these latest drilling results, Loncor President Peter Cowley said: "LADD029 is one of the most significant boreholes drilled at Adumbi with multiple zones of gold mineralization over an intersected width so far of 145.73 metres and indicates the significant, underground mineral resource potential below the 3.66 million ounces of the Adumbi open pit. It is also the deepest hole drilled to date and extends the gold mineralization down to 805 metres below the elevation of Adumbi Hill (see Figures 1 and 2). In addition, LADD029 intersected the thickest banded ironstone formation (BIF) package ever drilled at Adumbi (148 metres true thickness) and demonstrates that the favourable, mineralized BIF host is still going strong and increasing in thickness with depth in the northwest of the deposit (see Figure 2). Gold mineralization at Adumbi is directly related to the favourable chemical and physical properties of the BIF."

Quality Control and Quality Assurance

Drill cores for assaying were taken at a maximum of one-metre intervals and were cut with a diamond saw, with one-half of the core placed in sealed bags by Company geologists and sent to the Company's on-site sample preparation facility. The core samples were then crushed down to 80% passing minus 2 mm and split with one half of the sample up to 1.5 kg pulverized down to 90% passing 75 microns. Approximately 150 grams of the pulverized sample was then sent to the SGS Laboratory in Mwanza, Tanzania (independent of the Company). Gold analyses were carried out on 50g aliquots by fire assay. In addition, check assays were also carried out by the screen fire assay method to verify high-grade sample assays obtained initially by fire assay. As part of the Company's QA/QC procedures, internationally recognized standards, blanks and duplicates were inserted into the sample batches prior to submitting to SGS Laboratory.
