Rakounga Gold Concession
Burkina Faso, West Africa

NexusGold GreenBelt Locator 20170908AfricaBurkinaFaso

The 250-square kilometre Rakounga gold property is contiguous to the Company's Bouboulou gold concession. The Property borders Bouboulou on the west and south sides and hosts the Bouboulou 1 gold showing, which is the southern extension of the Bouboulou 2 trend. Bouboulou 1 is an active orpaillage with shaft workings that extend down approximately 80 metres.

Two of the three known gold trends on the Bouboulou concession extend onto the Rakounga property.

Rakounga also features several additional orpaillages. Koaltenga is the largest with up to 800 metres of strike length.  The Porphyry orpaillage measures approximately 150 metres in length, hosted in plutonic rocks.  Gounga is the smallest, measure approximately 75 metre long. 

Early rock sampling done by the company has yielded positive results at each orpaillage.  To date, four rock samples were collected from the Porphyry orpaillage returning elevated gold values of 19.95 gram per tonne (“g/t”) gold (“Au”), 2.57 g/t Au, and 1.175 g/t Au, respectively. 

A total of eight samples were collected from workings from the Gounga orpaillage, located approximately 1000 metres south of the Porphyry orpaillage.  Samples GGA-05 and GGA-07 returned gold values of 14.90 g/t Au, and 5.30 g/t Au, respectively. 

Initial rock samples from dumps of the artisanal workings at the Koaltenga orpaillage returned values of 17.30 g/t Au, 2.33 g/t Au, and 1.45 g/t Au, respectively. 

Significant results were returned from drilling at the Koaltenga orpaillage where drill holes RKG-17-RC-008 returned 34 metres of 1.00 grams per tonne (“g/t”) gold (“Au”), including four metres of 5.60 g/t Au, and drill hole RKG -17-RC-009, which returned 22 metres of 0.57 grams per tonne gold, including four metres of 2.01 g/t Au. 

The RC drill program was designed to test three artisanal workings (“orpaillages”), Namely Koaltenga, Porphyry and Gounga.  A total of 10 holes were drilled on the Koaltanga while five holes were drilled on each of the Porphyry and Gounga orpaillages, respectively.  The program was designed to test for gold mineralization extent along strike and to depth of structures being worked by the artisanal miners.

Significant results of the completed 10-hole Koaltenga drill program are tabled below:

The workings at Koaltenga extend for at least another 300 meters to the northeast, with board intercepts containing zones running 4 to 6 grams suggesting a prominent primary structure which has permeated out into the surrounding schists and volcanic rocks.

Drilling from the Porphyry orpaillage located some 800 meters south east of the Koaltanga orpaillage was tested with five holes.  Gold mineralization was encountered in four of the five holes highlights are tabled below:

HOLE DIP FROM (metres) TO (metres) LENGTH (metres) GRADE (gram/tonne)
RKG-17-RC-013 -50 58 90 40 0.19
INCLUDES   68 78 10 0.29
RKG-17-RC-014 -50 108 148 40 0.19
INCLUDES   110 128 18 0.25
RKG-17-RC-015 -50 38 80 42 0.26

Gold values were not encountered as high as those at Koaltenga, but intersections of anomalous gold values over lengths of up to 38 meters attest to the gold enrichment occurring within this area of the permit and may be indicative of a larger gold system occurring around the intrusive rocks at the Porphyry orpillage.

HOLE DIP FROM (metres) TO (metres) LENGTH (metres) GRADE (gram/tonne)
RKG-17-RC-017 -50 124 168 44 0.11
RKG-17-RC-019 -50 30 48 18 0.11
RKG-17-RC-020 -50 152 174 22 0.19

Results from Gounga were generally low given the extent of the workings on surface.  Drill holes RKG-17-RC-17, RKG-17-RC-019 and RKG-17-RC-20 did return anomalous values from a black mudstone with abundant pyrite occurring along bedding planes. 

The 105-line nine kilometer soil sampling survey was designed to investigate the gold bearing potential on the permit ground occurring between the Koaltenga gold zone, located near the western boundary of the Rakounga concession, and Pelatanga-Rawema gold trend, on the Company's adjacent Bouboulou exploration permit. 

Results from the survey successfully identified an anomalous gold trend which extends for approximately 7,000 meters (seven kilometers) along the southwest-northeast axis and broadens to widths of 2,500 meters. The newly identified 7,000-meter gold trend at Rakounga aligns with the 5km Pelatanga-Rawema ("PR") trend previously identified on the adjacent Bouboulou concession, indicating the mineralized footprint at the combined Bouboulou-Rakounga concessions now exceeds 15km in length.

These resuts established continuity of the gold trends at Bouboulou onto the adjacent Rakounga concession. The results indicate a sizeable trend extends from the northeast of Bouboulou to the southwest of Rakounga.
