Vancouver-based Nexus Gold Corp. has announced the commencement of its phase two diamond drill program at the 178-square kilometer Niangouela exploration permit located approximately 85 kilometers north of Ouagadougou, Burkina Faso.
The 2000m phase two program is to test down the dip and strike extensions of gold mineralization identified by the company in its phase one program.
The program will also test additional targets identified through surface mapping and prospecting. Results will be released once received, reviewed and verified, the company said.
The first phase diamond drill program was designed to test ground defined by anomalous rock samples collected from underground artisanal workings and anomalous Rotary Air Blast (RAB) drilling completed by the Company in December 2016.
“This initial program successfully intersected gold mineralization in eight of the first nine holes drilled on the concession. The mineralization was contained in a silicified shear zone occurring in the host granite. Quartz veining is associated with the shear zone,” the company explained.
The disclosed that the initial assays from the first nine diamond drill holes at Niangouela, as announced in the Company’s March 7, 2017, news release, have undergone additional analysis.
The Company said it applied metallic screen analysis and bulk leach extractable gold (BLEG) analysis, in addition to gravimetric fire analysis.
“This additional analysis has resulted in the change in values of several intercepts originally released on March 7, including hole NGL-17-DD-008 which saw an increase from 8.50 g/t gold over .62 metre, to 11.7 g/t gold over .62 metre, and from 120 g/t gold over 1 metre, to 132 g/t gold over 1 metre. In addition, hole NGL-17-DD-009 increased from 2.61 g/t gold over 4 metres to 2.95 g/t gold over 4 metres. This hole also gained an additional 1 metre of 5.00 g/t gold.
“The presence of free gold and the results of the BLEG and metallic screen analysis has demonstrated the need for ensuring that the maximum amount of material is being analyzed,” said Senior Geologist Warren Robb. “The company will be employing the appropriate method to gain the most representative gold value as is possible.” Continued Mr. Robb.
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 said it 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.
About the Niangouela Gold Concession
The 178 sq km Niangouela gold concession is located on the Boromo Greenstone Belt and is proximal to the Kalsaka deposit and the Sabce Shear Zone. It is accessible by road and has one major orpaillage (artisanal workings).
In December 2016 the Company conducted an 802m rotary air blast (RAB) drill program that delineated an approximately 1,000-metre (1km) quartz vein and a 500-metre secondary strike, running oblique to the main vein. This vein has now been identified in trenches, artisanal workings and through RAB drilling. It remains open in all directions.
A total of 11 rock chip and grab samples were taken during the initial exploration phase. Sample NG005, taken directly from the primary quartz vein at 46m depth returned a value of 2,950 g/t gold. Sample NG007 contained coarse visible gold, and was taken from material extracted from a depth of approximately 60m, returned a value of 403 g/t gold. Sample NG008, a single large piece of primary quartz vein containing host rock inclusions and a cluster of visible, returned a value of 49.8 g/t gold.
The company then followed up with the first ever diamond drill program at the concession. Eight of the first nine drill holes successfully intercepted gold, with highlights including 26.69 g/t gold over 4.85m (including 1m of 132 g/t gold), and 4.00 g/t gold over 6.2m (including 1m of 20 g/t gold). All mineralization in these first nine holes was present at depths of 57m to 124m below surface.
