Groundrush Project ML 22934 Annual Report for the period 14 September 2022 to 13 September 2023

Abstract

This report describes exploration activities for gold completed by Northern Star (Tanami) Pty Ltd on ML 22934, between 14 September 2022 and 13 September 2023. The project is located approximately 600 km northwest of Alice Springs along the Tanami Road. The Groundrush Project forms part of a larger Joint Venture agreement between Tanami Gold (NT) Pty Ltd and joint venture partner and manager Northern Star (Tanami) Pty Ltd, a wholly owned subsidiary of Northern Star Resources Limited. Work completed during the reporting period comprised of diamond and RC drilling at the Groundrush North, Groundrush, Groundrush-Ripcord Link, Ripcord and Tandem prospects and included the continuation and extension of some of the holes reported previously. 107 new holes were drilled but all up work involved 119 holes for 19,630.5 m. This included 105 RC holes for 14,480 m, 13 DD tails for 4,268 m and 1 DD from surface hole for 882 m. The RC holes included 4 precollar holes for 699 m. Preliminary results confirm the prospectivity at Groundrush and Ripcord, warranting follow up work including underground and surface drilling. Logging, sampling, assaying and data validation will continue facilitating interpretation and geological model updates. While results at Tandem indicate a trend and plunge, the dimensions and grade are minimal. Additional drilling could aid in defining the mineralisation trend and plunge more thoroughly. ML 22934 will become the centre of production in the coming years once an underground drive can be established at Groundrush and underground exploration can commence.
