Roxgold (TSXV:ROG) reported final results from development infill drilling at the 55 Zone at its Yaramoko project in Burkina Faso.
As quoted in the press release, highlights of results included:
- 73.9 grams per tonne (“gpt”) gold over 5.5 metres (4.4 metres estimated true width) in diamond drill hole YRM-15-DD-368a;
- 91.2 gpt gold over 2.6 metres (2.1 metres estimated true width) in diamond drill hole YRM-15-DD-375;
- 20.4 gpt gold over 6.0 metres (5.2 metres estimated true width in diamond drill hole YRM-15-DD-352;
- 13.5 gpt gold over 8.8 metres (7.3 metres estimated true width) in diamond drill hole YRM-15-DD-354; and
- 24.3 gpt gold over 4.4 metres (3.6 metres true width) including 107.0 gpt over 1.0 metres (0.8 metres true width) in diamond drill hole YRM-15-DD-328.
The release also stated:
The 48 holes released today (DDH328 – DDH375) are the remainder of the Company’s infill drilling program at the 55 Zone, which commenced in Q1 2015. The entire program totalled 75 holes for a total of approximately 6,900 metres of diamond drilling, to depths of up to 150 metres.
These results, incorporated with the results for the 28 previously released holes (See Company disclosures April 14, 2015 and May 19, 2015), account for the completion of infill drilling for the upper 100 metres of the deposit along the entire strike length of the 55 Zone (See Figure 1). The continuity and the high grade nature of the results continue to support the feasibility resource model with intersections consistent with the Company’s expectations. Overall, the infill drilling program has highlighted places within the model where, with greater resolution in the data and geological context, the Company believes that localized improvements to the model may be realized. To the west of the deposit, where a small section of the 55 Zone bifurcates, results were more variable than to the east; however this variability is consistent with previous drilling in this part of the deposit.
The existence of a small number of historical voids believed to have been created by artisanal miners, were intersected in drilling in localized areas down to a maximum depth of 50 metres. Infill drilling below these voids did not encounter the continuation of these voids, and they appear to be limited laterally along strike as well. The voids are believed to be sub-vertically excavated tunnels from surface and are not expected to have any significant impact on mining activities. Voids intersected in holes YRM-15-DD-328, 329, 330 and 334 occur over a strike length of 50 metres at a depth of approximately 50 metres. The feasibility mine plan incorporated footwall development in this area and as such the voids are not expected to significantly impact ore recovery. Voids intersected within the western portion of the 55 Zone (YRM-15-DD-350, 359, 361, 368a, 371 & 372) were intersected mostly within 30 metres from surface and are not expected to impact mineral resources or planned mining activities in these areas.
The 55 Zone is no longer an active artisanal mining site and the Company has erected a secure perimeter fence around the surface expression of the 55 Zone.
Roxgold CEO, John Dorward, said:
The successful completion of this program is another milestone on the road to production for the 55 Zone. The integration of these results provides additional confidence in our mine plan as we move towards production in the second quarter of next year.
