LATEST HOLE DRILLED AT LONCOR'S ADUMBI DEPOSIT INTERSECTS SIGNIFICANT WIDTHS AND GRADES IN MULTIPLE GOLD ZONES
Loncor Resources Inc. has released further significant assay results from its drilling program within its 84.68-per-cent-owned Imbo project in the eastern part of the Ngayu greenstone belt in the Democratic Republic of the Congo. Borehole LADD013 drilled at its flagship Adumbi deposit, intersected 20.00 metres grading 4.21 grammes per tonne (g/t) gold (including 11.00 metres grading 6.91 g/t Au), 17.30 metres grading 2.48 g/t gold (including 8.20 metres grading 4.71 g/t Au) and 7.04 metres grading 2.68 g/t gold.
Mineralized sections for borehole LADD013 are summarised in the table below:
Borehole Number From (m)To (m)IntersectedWidth (m)Grade (g/t) Au LADD013 394.06 401.10 7.04 2.68 LADD013 418.65 438.65 20.00 4.21 LADD013 including 419.75 430.75 11.0 6.91 LADD013 452.30 469.60 17.30 2.48 LADD013 including 457.35 465.55 8.20 4.71
Borehole LADD013 had an inclination of minus 72 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 85% of the intersected width. All intercepted grades are uncut with maximum internal dilution equal to or less than 4 metres of intersected width. Borehole LADD013 intersected the mineralization at a depth of approximately 65 metres below the open pit shell (see Figure 1 below).
Commenting on these latest drilling results, Loncor President Peter Cowley said: "Borehole LADD013 was targeting the northwest edge of the mineralization but encountered a better than expected thickness of the banded ironstone package as well as grades due to the increased higher grade zones of "Replacement Rock" drilled. This suggests a shallower northwest plunge to the mineralization than the previously indicated sub vertical plunge at depth (see Figures 1, 2 & 3 below). Our focus now is to outline substantial underground resources at depth below the 3.15 million ounce inferred resource pit shell where higher grades are being intersected."
The gold mineralization at Adumbi is associated with a thick package (up to a maximum of 130 metres) of interbedded banded ironstone formation (BIF) 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 3.46 million ounces of gold on Loncor's 84.68%-owned Imbo Project which contains the Adumbi, Kitenge and Manzako deposits (total inferred mineral resources of 43.0 million tonnes grading 2.51 g/t Au on these three deposits).
Barrick Joint Venture
Loncor received exploration reports from joint venture partner Barrick Gold, who are managing and funding the joint venture with Loncor that comprises several joint venture agreements and covers approximately 2,000 square kilometres of the Ngayu Archean greenstone belt (the "Joint Venture"). This Joint Venture area does not include Loncor's Imbo Project encompassing the Adumbi deposit, Loncor's Makapela deposit or Loncor's Yindi prospect. As announced previously, Barrick commenced a scout drilling program on a number of target prospects in the Ngayu greenstone belt, as well as continued to delineate additional priority targets for follow-up drilling. High priority targets were developed at Yambenda/Yasua, Mokepa and Mongaliema with scout drilling completed at Yambenda/Yasua and Mokepa. At Yambenda, four drill sections tested a 3.6 kilometre portion of the 9.5 kilometre long anomalous soil corridor. All the holes intersected mineralization associated to WNW shear structures developed at a contact zone between banded ironstone formation and volcano-sediments including conglomerates (similar host rock assemblage found at Kibali mine). Best drill intercepts included 14 metres grading 0.85 g/t Au in YBDD0001, 49 metres grading 0.52 g/t Au and 14.5 metres grading 1.38 g/t Au in YBDD0002 and 35.05 metres at 0.60 g/t Au in YBDD0006. At Mokepa, six scout holes were drilled with the best holes assaying 19 metres grading 1.04 g/t Au in borehole ADDD0001 and 46.7 metres grading 1.32 g/t Au in hole ADDD0002. Although large mineralized gold systems were delineated at both Yambenda and Mokepa, drill result grades were below Barrick's Tier 1 hurdle rates and, as a result, no further work is planned at these two targets.
At Mongaliema, the target area is a west-northwest trending shear zone hosted within altered metasediments with cherty units near the contact of a dolerite intrusive. Pitting has demonstrated that much of the area is covered by thick transported cover which hinders near surface exploration. Pitting was undertaken to the southwest of the trench which graded 32 metres grading 1.37 g/t Au. Results from pits in excess of 5 metres deep confirmed the southwestern extension, beneath thick transported alluvial material with an average high grade of 18.13 g/t Au from eleven samples. Further work is warranted from the results received to date at Mongaliema.
Barrick Gold has now informed Loncor that it will not be continuing exploration on the Joint Venture ground. Loncor will be assessing the results of the Barrick Joint Venture program to determine whether further exploration by Loncor on the Joint Venture ground is warranted. In particular, the Mongaliema target, which is only seven kilometres from Loncor's Makapela deposit, which 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), will be further explored by Loncor especially as this promising target has not been drilled by Barrick. Mongaliema will be evaluated to determine whether it has the resource potential to be combined with the nearby Makapela deposit. The high grade of the Makapela deposit also affords the potential for this resource to be transported to a central processing facility at Adumbi.
Loncor's aim is to continue to add and upgrade mineral resources to Adumbi's current 3.15 million ounce inferred resource (41.316 million tonnes grading 2.37 g/t Au), and commence a Preliminary Economic Assessment of Adumbi during this quarter.
