Democratic Republic of Congo – Gold explorer Burey Gold has successfully completed a reverse circulation drilling programme testing potential bedrock mineralisation underlying the >200ppb gold in soil anomaly and the strong NNW trending chargeability anomaly identified at its Giro Prospect in the Kilo-Moto Gold Belt DRC.

Additional holes were also planned under significant artisanal workings at Giro and under selected IP chargeability anomalies identified adjacent to the Main Zone in the recent ground IP geophysical survey.

A total of 103 holes were completed for 9 823m since Burey Gold commenced drilling at Giro. Results for the first 78 holes have been received with results from an additional 25 drill holes pending.

 

Highlights:

  • Gold mineralisation confirmed from surface with strike length of 1 400m and widths of between 350 and 450m, co-incident with strong IP anomaly – the Main Zone
  • Best recent results from the periphery of the Main Zone include; 30m grading at 1.14g/t of gold from 12m, 1m grading at 7.53g/t of gold from 90m (GRRC106), and 70m grading at 1.11g/t of gold from 35m (GRRC111)
  • Confirmation of Main Zone of mineralisation associated with the dominant NNW trending IP chargeability anomaly associated with the interpreted Kebigada Shear Zone
  • 9 823 metres of reverse circulation drilling now completed over total Giro prospect area of 1500m x 1000m
  • A diamond drill rig will now test the main mineralised zone depth potential and structural controls on mineralisation
  • Exploration focus now moving to artisanal workings at Adoku, Peteku west of Giro and historic Belgian workings to the north at Tora
  • Commenced infill soil sampling for better coverage of several newly identified soil anomalies

 

The drilling programme has confirmed that the Main Zone of mineralisation is associated with the dominant NNW trending chargeability anomaly associated with the interpreted Kebigada Shear Zone.

Gold mineralisation was further confirmed from surface over a strike length of 1 400m over widths of between 350 and 450m. The grade of mineralisation decreases to the north suggesting a potential northerly plunge component to mineralisation.

Low grade mineralisation with occasional narrow high grade zones including 1m grading at 7.53g/t of gold from 90m (GRRC106), 2m grading at 4.13g/t of gold from 28m (GRRC122) and 1m grading at 11.65g/t of gold from 80m (GRRC128) was reported from holes east of the main chargeable IP anomaly with best intercepts of 30m grading at 1.14g/t of gold from 12m in GRRC106 and 29m grading at 0.90g/t of gold from 14m, including 10m grading at 1.22g/t of gold from 23m in GRRC123.

An apparent diorite was also intersected in GRRC111 which reported 70m grading at 1.11g/t of gold from 35m and lies along the eastern end of the strong chargeability anomaly on Line 5.

Giro Gold will now commence drill testing the mineralised potential of known regional targets as well as those identified from soil sampling programmes and artisanal mining on both PE 5046 and 5049.

A diamond rig will be mobilised to site on completion of maintenance repairs to a small section of the access road.

Initial focus will be to drill a series of diamond holes at the Giro Prospect which will define the true width of the mineralised zone associated with the chargeability anomaly and will test the depth extensions of the mineralisation intercepted at shallow levels in the reverse circulation drilling, identify controlling structures on mineralisation, and define any potential high grade mineralised chutes similar to those at the nearby Kibali mine, owned by Randgold Resources.

The area to the north at Tora on PE 5049 will be soil sampled and artisanal workings mapped in detail in preparation for a first pass diamond drilling programme to follow the diamond drilling on the Giro Prospect.

Previous Belgian exploration mined two main areas, Mangote and Kai-Kai, where diamond drilling records at Mangote reported 0.6m grading at 37g/t of gold and 0.35m grading at 485g/t of gold from quartz veins.

Wall rock was not sampled and there is no record of methods used to obtain these results. Subsequent sampling of wall rock adjacent to quartz veins currently mined by artisanal miners confirmed potential for a broader zone of mineralization surrounding high grade quartz veins.

Channel samples collected previously included 11.5m grading at 0.89g/t incl. 7m grading at 1.12 g/t of gold and 3m grading at 1.18g/t.

A coherent NW trending soil anomaly >100ppb gold was defined at Peteku. Detailed mapping and sampling programmes to better identify drill targets are ongoing. Channel samples from granites at Peteku reported up to 4m grading at 21.7/t of gold and is one of the targets that will be tested by drilling. Testing is expecting to intersect several zones of narrow but high grade mineralisation as indicated by channel sampling at Peteku located 2km to the SW of Giro.

A new area of substantial artisanal workings is located 4km to the south of Giro at Adoku within the interpreted structural corridor. Artisanal miners are recovering substantial gold quantities from a 3m thick lateritic profile which extends over 400m x 200m. Two pits have exposed a limonitic saprolite with prominent quartz veins and stringers sub-parallel to the ENE trending granite contact immediately to the south. Numerous clasts of banded iron formation were also found within the workings suggesting mineralisation is closely associated with banded iron formation. All in situ workings have been sampled and an infill soil sampling programme has been planned to better define the anomaly which potentially extends over more than 5km from two parallel zones.

Results of channel samples are expected in October 2015.
