NEWFIELD RESOURCES LIMITED ASX Announcement 30 April 2021 ASX : NWF ABN : 98 153 219 848 15 McCabe St North Fremantle WA 6159 T : +08 9389 8880 www.newfieldresources.com.au MARCH 2021 QUARTERLY ACTIVITIES REPORT Newfield Resources Limited ( ASX : NWF ) ( Newfield or Company ) is pleased to announce its activities during the March 2021 quarter . • ■ • ■ ■ Highlights Underground development of the return airway on the Kundu kimberlite continued A total of 648 m of underground development achieved to date Bulk sample of 100 tonnes collected from the Peyima kimberlite dyke for Mineral Resource estimation purposes 910,000 carat JORC compliant inferred diamond resource ( + 1.0mm cut off ) declared for the Panguma Kimberlite * 498 Loss Time Injury Free dates recorded during the surface and underground construction and development activities completed at the Tongo mine * Refer to the ASX announcement dated 27 January 2021 1. Tongo Diamond Mine ( Sierra Leone ) During the quarter , the underground decline development and infrastructure construction continued , although progress continued to be hampered by delays imposed upon the supply chain , which has significantly increased lead times and reduced capacity to bring in certain mining equipment and spares . In addition , strong water ingress was intersected in January , requiring the construction of a new pump station to manage and pump the water to surface . The activity to manage this water ingress slowed the underground development progress during the quarter and limited the decline development to 125m . The total decline development to date is 648m and a further 148m of development is required along Segment A RAW to reach the ventilation shaft . This , along with developing the Segment C RAW , will be the priority over the next three months ( refer Figure 1 ) . As a consequence of encountering the strong water ingress , the Company will commence its planned hydrological study . The study was foreshadowed as part of the FEED programme , once underground water was intersected , and has been budgeted in the mine plan . The study is expected to provide a more accurate assessment of the expected water ingress as the mine goes deeper . In the interim , the underground dewatering dam that has recently been constructed has the sufficient pumping capacity to maintain safe and dry underground working conditions . The water is clean and is gratefully received by the local farming community where it is being used to irrigate crops . Construction of the Refuge Bay is complete and awaits the installation of an air - line from surface to become operational .
