Burkina Faso - Industry News NEXUS GOLD COMMENCES DRILLING AT BOUBOULOU GOLD CONCESSION, BURKINA FASO, WEST AFRICA
Drilling has commenced at its 38-square-kilometre Bouboulou gold concession. Bouboulou is located approximately 75 kilometres north-west of the capital Ouagadougou, on the Boromo-Goren greenstone belt, and is bisected by the Sabce shear zone.
The 2,000 metre phase 1 diamond drill program at Bouboulou will target previously identified mineralized zones at the property, namely Bouboulou 2, Pelatanga and Rawema. In addition, the company will test the Koala zone, where recent samples ran as high as 66 grams per tonne gold, and the newly identified Rawema West zone.
New zone identified -- Rawema West
As reported in a June 6, 2017, news release, company geologists have now determined the presence of a new mineralized zone at Bouboulou through the observance of increased artisanal activity, and the result of rock sampling taken from the newly observed area.
The new zone, named Rawema West, occurs approximately 1,000 metres west of the main workings at the previously identified Rawema site. The artisanal workings extend approximately 150 metres in length and appear by observation to extend to depths of greater than 20 metres.
Company geologists collected seven select rock samples of dump material from the Rawema West workings. Of the seven samples collected there, four returned values greater than one gram per tonne gold, including BBL-004, which returned 9.49 grams per tonne.
The sampling results greater than one gram per tonne gold from both Rawema West and Koala, as reported June 6, 2017, are shown in the attached table.
Sample ID Gold Sample type (g/t) BBL-004 9.69 Select BBL-005 2.62 Select BBL-006 4.41 Select BBL-007 4.84 Select BBL-012 66.1 Select BBL-013 29 Select BBL-014 2.20 Select
The trend of the workings at Rawema West runs roughly parallel to the Pelatanga-Rawema (PR) trend that the company intends to test with its coming diamond drill program.

Bouboulou trends
The company has subsequently identified three distinct 5,000-metre-long (five kilometres) anomalous gold trends at the Bouboulou concession. Each of the three trends display strong coincidental geochemical and geophysical gold anomalies and extend from the four previously drill-identified mineralized zones, namely Rawema, Pelatanga, Bouboulou 2 and Koala. They are identified by numerous orpaillages and geochemical samples of greater than one gram per tonne gold. All three of the Bouboulou trends display similar coincidental anomalies. Each trend has substantial artisanal workings either directly on them or along trend.
A map of the three trends can be seen on the company's website.
