Phase One Diamond Drill Program
A phase one 2000m diamond drill program at Niangouela began in January 2017 with the objective to test the primary quartz vein and associated shear zone at depth and along strike while targeting areas of gold anomalies identified from rock samples and RAB drilling. The drilling successfully intersected the shear zone for over 200 metres along strike and to depths of 105 metres below surface. The shear zone remains opens along strike and to depth.
Results from the phase one program delivered gold in eight of the first nine holes drilled, with several intercepts of note. They include NGL-17-DD-008, which returned 26.69 g/t gold over 4.85 metres (including 8.50 g/t gold over 0.62 metre, and 120.00 g/t gold over 1.03 metres). Hole NGL-17-DD-006 returned 4.00 g/t gold over 6.20 metres (including 20.50 g/t gold over 1.00 metre). NGL-17-DD-009 returned 2.61 g/t gold over 4.00 metres (including 5.92 g/t gold over 1.00 metre), and NGL-17-DD-003 returned 1.80 g/t gold over 5.10 metres (including 6.14 g/t gold over 1.10 metres).
The assay results from the phase one program are tabled below:
|Hole ID||Azimuth||Dip||FROM (m)||TO (m)||INTERCEPT (metres)||Au gram/tonne|
|NGL-17-DD-005||185||-70||NO SIGNIFICANT RESULTS|
¹ Denotes metallic screen analysis
² Denotes gravimetric fire assay analysis
3 Denotes bulk leach extractable gold analysis
Note all assay results represent intercept lengths and are not true widths
The sampled core was delivered to the independent Actlabs laboratory in Ouagadougou where the samples underwent analysis by fire assay with an atomic absorption finish. If samples returned values greater than 10 ppm gold the sample was re-analysed by gravimetric fire assay. Samples with identified visible gold were analysed using a fire assay metallic screen analysis. The Company employs a QA/QC program of inserting standards, blanks and duplicates into the samples stream as a supplement to the internal checks employed by Actlabs.
