ENCOURAGING results have been received from the 2016 drilling campaign at Era Resources’ Yandera Copper Project. The drilling may add extra resources with an updated estimate expected by the end of 2016.

A total of 43 diamond drill holes comprising 8917 metres were completed at Yandera during the program, which was designed to infill and expand the resource, testing opportunities within and around the margin of the known resource.
Drilling focused on infill in the Dengru, Dimbi, South Dimbi, Gremi, Imbruminda, Gamagu, and Kauwo areas, as well as testing proximal areas, including targets east of South Dimbi, east of Omora, at East Gremi and at Benbenubu.
At Dengru four holes for 924 metres were completed. Drilling intersected copper mineralisation in material previously classified as waste within preliminary open pit models based on the 2015 estimate. The results fill gaps in data and are expected to increase the estimate locally and convert some in-pit waste to resource. Two holes intersected good mineralisation within the current open pit shell that could connect Gremi and Omora areas in future pit designs.
Six holes for 1210 metres were completed at Omora. Drilling also intersected mineralisation at the edge of the 2015 estimate. Results from one hole may expand the open pit boundary to the east.
Six holes for 1358 metres were completed at Benbenubu. Targets focused on mineralisation east of known mineralisation at Dengru and Omora areas. Drilling intersected additional mineralisation likely to add resource to the eastern side of the 2015 estimate.
Results from two holes show relatively shallow copper mineralisation near historical results that are likely to build the resource to the east. Results from another show good copper mineralisation likely to add resource between Omora and Benbenubu.
Eight holes for 1624 metres were completed at South Dimbi. Drilling intersected additional mineralisation within and beneath open pit shells. Results from one hole show previously unknown mineralisation within the model 2015 resource pit, which is likely to add resource and potentially locally increase the average grade. Results from another show mineralisation thought to be a further extension of a mineralised trend intersected previously.
Five holes for 936 metres were completed at East Gremi. Targets focused on mineralised trends thought to extend southeast from known mineralisation in the South Dimbi area. Mineralisation here is likely to add resource along these trends outside the 2015 estimate.
