Era Resources Inc. (“Era” or the “Company”) (TSX VENTURE:ERX) is pleased to announce completion of resource drilling and further assay results from the 2016 Infill and Proximal Drill Campaign at the Yandera Project, the goal of which was to advance a large porphyry copper system in the highlands of Papua New Guinea.
Yandera Drilling Update
A total of 43 diamond drill holes comprising approximately 8,917 metres were completed at the Yandera Project during the 2016 drill program. The program was designed to infill and expand the Yandera resource, testing opportunities both within and around the margin of the known resource where discovery of additional mineralization can significantly impact the current resource estimate and positively affect potential open pit designs. Drilling focused on infill in the Dengru, Dimbi, South Dimbi, Gremi, Imbruminda, Gamagu, and Kauwo areas, as well as testing some proximal areas, including targets east of South Dimbi, east of Omora, at East Gremi and within the Benbenubu areas (Figure 1).
The company has received assay results for an additional 13 drill holes (see locations on Figures 1-7). Hole locations and significant intersections are shown below in Tables 1 and 2. Assay results for 18 holes are still pending.
A total of four holes for 924 metres were completed at Dengru (including YD578 and YD580). Drilling at Dengru (Figure 2) intersected copper mineralization in material previously classified as waste within preliminary open pit models based on the 2015 resource estimate. These results fill gaps in drilling data and are expected to increase the resource estimate locally and convert some in-pit waste to resource. Both YD578 and YD580 intercepted good copper mineralization within the current open pit shell, that could connect the Gremi and Omora areas in future pit designs.
A total of six holes for 1,210 metres were completed at Omora (including YD576). Drilling at Omora (Figure 3) intersected mineralization at the edge of the 2015 resource estimate. Results from YD576 may allow the boundary of the open pit to be expanded to the east to incorporate new resource.
A total of six holes for 1,358 metres were completed at Benbenubu (including holes YD582, YD584, and YD586). Targets at Benbenubu focused on mineralization to the east of known mineralization at the Dengru and Omora areas. Drilling intersected additional copper mineralization likely to add resource to the eastern side of the 2015 resource estimate (Figure 4).
Results from YD582 and YD584 show relatively shallow copper mineralization proximal to historical results that are likely to build the resource to the east. Results from YD586 show good copper mineralization likely to add resource between the Omora and Benbenubu areas.
A total of eight holes for 1,624 metres were completed at South Dimbi (including holes YD577 and YD581). Drilling at South Dimbi (Figures 5 and 6) has also intersected additional copper mineralization both within and beneath the open pit shells based on the 2015 resource estimate. Mineralization at South Dimbi appears to occur within structurally controlled zones of altered granodiorite with dikes of porphyritic quartz diorite and porphryritic dacite.
Results from YD577 show previously unknown copper mineralization within the model 2015 resource pit, which is likely to add resource and potentially locally increase the average grade in portions of South Dimbi (Figure 7). Results from YD581 show copper mineralization thought to be a further extension of a mineralized trend intersected in YD569, which may add resource to the eastern area of South Dimbi.
A total of five holes for 936 metres were completed at East Gremi (including holes YD583, YD585 and YD587). Targets at East Gremi focused on mineralized trends thought to extend to the southeast from known copper mineralization in the South Dimbi area. Drilling intersected copper mineralization likely to add resource along these trends outside of the 2015 resource estimate.
Results from YD583, YD585 and YD587 show copper mineralization thought to extend to the southeast beyond the South Dimbi area, which may add new resource to the East Gremi area (Figures 5 and 6).
Gremi, Dimbi, Imbruminda, Gamagu and Kauwo
At Gremi, two holes for 408 were completed (including YD579). Results for YD579 show mineralization at the northeastern edge of Gremi and constrain a geologic boundary for mineralization (Figure 6).
At Dimbi, six holes totaling 1,272 metres were completed (including YD574). Targets in the Dimbi area focused on converting material within the model 2015 pit to resource and testing for mineralization that may connect with the Gamagu area.
Results from YD574 at the southeastern edge of Dimbi did not intersect copper grades above 0.15% Cu; however, the hole did constrain an important geologic boundary for mineralization (Figure 7).
At Imbruminda, three holes for 611 metres were completed. At Gamagu, two holes for 407 metres were completed. At Kauwo, one hole for 167 metres was completed.
Results from the drilling completed at Yandera to date continue to be encouraging and are expected to allow conversion of some material classified as in-pit waste to resource and may add additional resource by allowing local expansion or deepening of the conceptual open pit design based on the 2015 resource estimate. Overall, these results are expected to expand the resource estimate and improve the waste to resource ratio in portions of the modelled open pit shells. An updated resource estimate for the Yandera Project incorporating all the results from the drilling campaign is planned to be completed by the end of 2016.

|Table 2. Significant intersections from assay results of the latest 13 holes of drilling at Yandera. Results are grouped by area. Composites were based on a 0.150% Cu cut-off, as used in the 2015 resource estimation and may include up to 10 metres internal waste. Intervals are based on drilled thicknesses and may not reflect true thickness. Note that ppm is parts per million and 1ppm = 1 gram per tonne. Note that YD574 is not listed in the table below as it had no intersections above 0.15% Cu.|

Analyses were completed by ITS (PNG) Limited, a laboratory independent of the Company located at Lae, PNG, utilizing fire assay and multi-element ICP-AES methods with internal checks, blanks, duplicates and standards at various intervals in the sequence of samples. Era also inserted standards and blanks within the sequence of samples of halved core. The results of quality control samples indicate that the assays are reliable. Intervals of core sampled were generally 3 metres in length.
