Loncor Continues To Drill High Grade Gold Intersections At Its Makapela Prospect, Ngayu Project

Results include 4.35 Metres Grading 17.55 G/T Au, 5.63 Metres Grading 13.79 G/T Au and 3.47 Metres Grading 24.94 G/T

TORONTO, May 16 /CNW/ - Loncor Resources Inc. (the "Company" or "Loncor") (TSX-V: "LN") (NYSE AMEX: "LON") is pleased to announce further high grade drilling results at the Company's Makapela prospect, Ngayu Gold Project, northeastern Democratic Republic of the Congo (the "DRC").

Exploration at Makapela is focusing on a quartz vein system being exploited by artisanal miners in three large pits (Main, North and Sele Sele) which are each between 170 meters and 290 meters in length, located along a strike of 2.2 kilometers. Soil geochemical results indicate that the mineralization continues between these three artisanal workings under a thick soil cover.

Results have been received for an additional 7 drill holes at Makapela and are reported in Table 1 below. Also, results are now available for additional vein intersections in two earlier reported drill holes, which are also included in Table 1. These boreholes intersected the mineralization at vertical depths of between 32 meters and 244 meters below surface. The holes were inclined at between minus 50 degrees and minus 71 degrees, and averaged 209 meters in depth with a maximum downhole depth of 356 meters. Core recovery averaged 98% within the mineralized sections.

From this additional drilling to date (total of 19 core holes), a better understanding of this mineralized system is becoming apparent. It is now interpreted that the main mineralised vein, now termed "Vein 2", occurs in the North artisanal pit over a strike length of at least 640 metres, while the mineralised vein in the Main pit, now termed "Vein 1", is a possible splay off Vein 2 in the footwall.

Vein 2 has been intersected on the North pit trend over a strike length of 640 metres down to a maximum vertical depth of 244 metres (open at depth and along strike). The average true width of Vein 2 intersected to date is 4.21 metres with an average grade of 13.09 g/t Au. The most significant intersection is 4.30 true thickness metres grading 64 g/t Au in drill hole NMDD005. Vein 2 tends to have a smokey grey brecciated texture with common disseminations and stringers of pyrite and locally pyrrhotite.  The vein appears to have followed a shear zone within and on the margins of a 2 - 4 metre thick unit of banded iron formation (BIF), and is parallel to the lithological strike.

Vein 1 has been intersected on the Main pit trend over a strike length of 320 metres down to a maximum vertical depth of 198 metres (open at depth and along strike). The average true width of Vein 1 intersected to date is 1.92 metres with an average grade of 13.95 g/t Au. The most significant intersection is 2.05 true thickness metres grading 24.94 g/t Au in drill hole NMDD014. Vein 1 tends to have a glassy, white massive texture and pyrite is much less common than in Vein 2.  The vein crosscuts the lithologic strike and is possibly a splay off Vein 2.

Two kilometres to the north of the North pit, the probable continuation of Vein 2 at the Sele Sele pit has been intersected over a strike length of 320 metres (open at depth and along strike). From the limited drilling to date at Sele Sele, the mineralization appears to be locally thicker but lower grade than further south at North and Main pits.

Although it was previously thought that this quartz vein system was found at the lithological contact of an intermediate and basic volcanic cycle, further mineralogical studies indicate that Veins 1 and 2 are located within a series of basalt flows and dolerite sills.  The presence of several thin units of BIF indicate periods of quiescence between volcanic episodes, and in the case of the Vein 2 structure, shearing has preferentially taken place at the BIF-basalt contact.

Detailed plan locations of the drill holes together with cross sections are published on the Loncor website with this press release (link: http://www.loncor.com/s/NewsReleases.asp?ReportID=457166).

A third rig is being mobilised to Makapela to accelerate the drilling of Veins 1 and 2 along strike and to a maximum depth of 400-500 metres.

Commenting on the latest drilling results from Ngayu, Peter Cowley, President and C.E.O. of the Company, said: "We continue to be encouraged by the number of high grade intersections at Makapela. The goal of our drilling campaign at Makapela for 2011 is to demonstrate continuity along strike and at depth and to begin delineating the mineral resource."

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 SGS Laboratory (which is independent of the Company) in Mwanza, Tanzania. The core samples were then crushed down to minus 2 mm, and split with one half of the sample pulverized down to 90% passing 75 microns. Gold analyses were carried out on 50 g aliquots by fire assay. Internationally recognized standards and blanks were inserted as part of the Company's internal QA/QC analytical procedures.
