New Zone Identified In Goldfields Project
Errawarra Resources Ltd (ASX:ERW) has identified a zone of gold mineralisation which is open at depth and along strike on its Binti Binti Gold Project located 75 km north-northeast of Kalgoorlie, Western Australia.
High-grade assay results have now been received from an aircore programme conducted at Binti Binti Project during March and April 2021m with the drilling programme successfully testing several areas of interest for gold mineralisation
Gold grades of more than 5 g/t Au were intersected in two holes. These holes were drilled in an area interpreted to be highly prospective due to its location beneath a shallow prospector’s pit, where previous grab sampling had returned significant gold results (227.2 and 1.2 g/t Au in two separate samples). The drill intersections were:
- EBBAC219: 8.0m @ 2.76 g/t Au from 26m, including 4.0m @ 5.09 g/t Au; and
- EBBAC218: 1.0m @ 6.61 g/t Au from 15m.
Hole EBBAC219 returned a peak assay of 8.4 g/t Au over one metre from 29m, while EBBAC218 also returned 0.13 g/t Au from 12m down hole.
The high-grade results were encountered in what appear to be steeply dipping quartz veins, indicating that the gold intersected relates to a bedrock gold system (rather than a surface upgrading) and may persist at depth. The results to date highlight a zone of gold mineralisation which is open at depth and along strike.
A further drill hole, EBBAC220, drilled along strike to the east from EBBAC219, intersected a number of intervals of low-grade mineralisation including 1.0 m @ 0.39 g/t Au from 15m down hole.
Interpretation of the structure from geological mapping in this area suggests that any shoots of gold mineralisation are likely to plunge very steeply. This is consistent with the orientation of the high-grade mineralisation interpreted from intersections in drill holes EBBAC218 and EBBAC219. The significance of these results is being assessed in the context of local structural controls and other drill results.
In addition to the high-grade intersections, a further 13 holes contained low-grade, yet significant gold mineralisation hits of >0.1 g/t Au. These intersections are broadly spread across the project area along interpreted mineralised trends. A number of these intersections occurred at end of hole (holes terminated due to intersection of hard bedrock) suggesting that deeper drilling in these locations may yield further gold-bearing intersections.
A further 36 aircore drill holes returned anomalous gold results of greater than 20 ppb Au. These intersections, while not of economic grades, have revealed (and confirmed) the location and orientation of fertile structures that may potentially host significant gold mineralisation somewhere along their length.
This will provide focus for future exploration targeting along with a number of other locations where low-grade gold mineralisation was detected.
