Loncor Resources Inc. announced initial bottle roll metallurgical testwork results at the Company's Makapela prospect, Ngayu Gold Project, northeastern Democratic Republic of the Congo. Bottle roll is a preliminary metallurgical test to determine how much and how easily gold may be liberated from an ore using cyanide. Exploration at Makapela is focusing on a quartz vein system within a sequence of basalts, thin units of banded iron formation, and dolerite sills. The veins are currently being exploited by artisanal miners in three large pits which are each between 170 metres and 290 metres in length, located along a strike of 2.2 kilometres. Soil geochemical results indicate that the mineralization continues between these three artisanal workings under a thick soil cover. Drill core assay results have been previously reported for 36 boreholes. For this preliminary metallurgical testwork, a number of core samples were used from the previously reported Vein1, Vein 2 and Sele Sele vein intersections. For Reef 1, ten core samples from two boreholes with grades from 2.50 g/t to 59.03 g/t Au (average grade 19.6 g/t Au) were used for the testwork and for Vein 2, 15 core samples from two boreholes with grades from 1.29g/t to 76.33 g/t Au (average grade 15.24 g/t) were utilised. From the Sele Sele area, 14 core samples from one borehole grading 2.54 g/t to 18.17 g/t Au (average grade 7.30 g/t Au) were used. For the bottle roll testwork, each core sample was crushed down to minus 2mm and pulverized down to 90% passing 75 microns. Triplicate samples were analysed by fire assay to determine the average head grade of each sample. A 1.5kg pulverised sample was then bottle rolled for 24 hours in a dilute cyanide solution to extract the gold.
