Democratic Republic of Congo – Gold explorer Burey Gold has begun a diamond drilling programme on the Kebigada Shear Zone at the Giro vein at the Giro prospect, located within the Kilo-Moto gold belt, in north-east Democratic Republic of Congo (DRC).

Highlights:

  • The 2 440 m diamond drill programme is aimed at identifying targets at the Giro, Peteku, Mangote and Kai-Kai prospects at the Giro gold project
  • A diamond drill rig is on site at Giro/Kebigada and has commenced drilling to test the vertical extent and identify structural controls on  mineralisation
  • Ongoing soil sampling and mapping programmes continuing along the NNW-trending structural corridor to identify new areas of gold  mineralisation
  • Extensive artisanal alluvial workings identified within the corridor enhance potential for discovery
  • Reverse circulation (RC) drill results received from the remaining 25 holes for 2 431 m from the periphery of  the 2 000 m long mineralised zone within Kebigada Shear  Zone
  • The results from diamond drill programme are expected in the first quarter of 2016.

The drilling is in an area which was previously successfully mined during Belgian colonial rule, and where significant drilling results have been reported by Burey Gold.

Additional holes will test the mineralised potential of the Peteku target as well as the true mineralised widths and grades of open pits and adits mined by the Belgians at Mangote and Kai-Kai respectively at the Giro project.

Recent RC drilling supported by the ground IP survey has defined a main zone of significant mineralisation which extends for more than 1 km x 400 m within the Kebigada Shear Zone at Giro.

Narrow zones of mineralisation extend for almost 2 km along the shear and will be followed up in future drilling programmes. RC drilling was carried out on 200-250 m line spacing and reached maximum vertical depths of 90 m. Interpretation of the gradient array in the recently completed IP survey suggests that best grades and widths of mineralisation were reported from the intersection of two main structural features, the NW trending regional fabric associated with the Giro vein and the NNW orientated structural corridor.

Latest work

Planned diamond drilling of 1 300m aims to confirm the continuity of mineralisation at depth below the RC drilling, where several high-grade zones were defined within a broader lower grade envelope of mineralisation. The drilling will also define structural controls on mineralisation and will define any plunge component associated with the intersection of the two dominant structural trends.

Two holes totalling 160 m will also test the Giro vein at depth. More than 300 m of strike along the Giro vein was mined during Belgian colonial rule, and although little information is available it is reported that a 6 m wide zone at a grade of approximately 15g/t of gold was mined. One RC hole drilled during Panex Resources’ first drilling campaign reported 8 m at 7.28g/t gold from 52 m including 3 m at 18.25g/t gold from 55 m.

All results have now been reported for Burey’s recently completed RC drilling programme at Giro. Results show that mineralisation within the Kebigada Shear Zone is open to the north and south and has been defined over approximately 2km. Best mineralised intercepts from these latest results included:

  • GRRC133 5 m grading at 2.73g/t gold from 15m
  • GRRC135 14 m grading at 1.35g/t gold from 38m
  • GRRC152 6 m grading t 2.35g/t gold from 4m.

Follow-up and infill drilling will define the mineralised depth potential of the Kebigada Shear Zone. An intercept of 3 m at 7.91g/t of gold from 85 m in GRRC143 is associated with a chargeability anomaly having the same orientation as the Giro vein albeit on the opposite side of the Kebigada Shear boundary.
